Simplifying SEER and Understanding Your HVAC Unit

 

The Definition of SEER

What is SEER? The short and simple explanation of SEER is that it’s a number assigned to an AC unit indicating its energy efficiency. The higher the SEER number, the more energy efficient the system is, which is important because an energy-efficient unit will not only reduce your monthly utility bills, but will also reduce your carbon footprint, thereby benefitting the environment. Naturally, then, it would make sense to purchase an AC unit with the highest SEER rating available, right? Well, not necessarily. As we explain a little more about the SEER rating, you’ll understand why a high-rated SEER unit may not be the right one for you.

 

S-E-E-R – Breaking it down

SEER stands for “Seasonal Energy Efficiency Ratio.” The key word to remember in this acronym is “Seasonal,” as the SEER number is determined by measuring an AC unit’s efficiency as it operates over a period of time with varying degrees of temperature and humidity levels, which mimic a typical summer season for most areas in the U.S. This is typically referred to as the “cooling season.”

SEER ratings are calculated by measuring the amount of cooling provided (energy output, measured in BTU’s), during a cooling season and dividing it by the amount of energy consumed (energy input, measured in watts), over this same period of time. An AC unit that uses less energy to produce the same amount of cooling than another unit over the cooling season, operates more efficiently and will have a higher SEER number. Of course, the higher the SEER number, the more expensive the unit, but oftentimes the savings recouped from a more energy-efficient unit make up for the higher upfront cost. For example, if you replace a SEER 10 unit with a SEER 13 unit, then the same amount of cooling will be produced while using 30% less energy! That’s a 30% reduction in harmful emissions and a 30% reduction in your utility bill.  If you have a unit with a SEER rating that’s less than 10, and you upgrade to a SEER 13, or higher, then the energy and cost savings will be even greater.

When shopping for a new AC unit, the SEER rating is an important piece of information that allows you to compare the energy efficiency of air conditioners and help determine an AC unit’s approximate annual operating costs.

 

SEER vs. EER

Oftentimes alongside the SEER rating, you will see an EER rating. EER stands for “Energy Efficiency Ratio” and is a number that measures an AC unit’s energy efficiency at a specific temperature, instead of over a period of time with different temperatures (hence, no “S” for seasonal). EER was created in 1975 by the Air Conditioning, Heating & Refrigeration Institute (AHRI) as a way of measuring the cooling efficiency of HVAC units. To determine the EER rating, the amount of cooling provided (energy output) is divided by the amount of energy consumed (energy input) while operating under a singular set of weather conditions, which is typically an outdoor temperature of 95^°F, an indoor temperature of 80^°F, and a humidity level around 50%.

Realizing that the EER rating doesn’t take into account certain variables, such as seasonal weather fluctuations and the resulting heat loss or gain that occurs when a system frequently cycles on and off, the SEER rating was developed in 1978 to more accurately gauge a unit’s efficiency during a typical summer season. The SEER rating, then, differs from an EER rating in that it is an average calculated over time; SEER is a measurement of an AC unit’s efficiency as it maintains a constant indoor temperature over the course of a cooling season with varying outdoor temperatures ranging from a low of 65°F to a high of 104°F with humidity levels ranging from 30% to 80%.

Just as with SEER ratings, a high EER rating indicates a more energy-efficient system and is a useful way to determine the efficiency of an AC unit when comparing across brands. However, the SEER number is a better indicator of an AC unit’s overall operational cost as it takes into account how well the unit works under a variety of weather conditions over the course of typical year. Just remember to always compare one unit’s EER to another’s EER, and SEER number to SEER number when looking at multiple units.

 

 

SEER by the Numbers (13/14 SEER, 16 SEER, 18 SEER, 21 SEER)

As previously mentioned, a SEER 10 unit replaced with a SEER 13 unit results in a 30% energy savings. What if you wanted to go even higher? Below is an example of the potential energy savings and cost savings of replacing a SEER 10 unit with a higher SEER-rated unit.

Based on a 3-ton AC with a SEER 10 rating that consumes around $1,323 in electricity per year:

• A SEER 18 unit will produce 44% in energy savings per year and consume around $735 in electricity per year.
• A SEER 21 unit will produce 52% in energy saving per year and consume around $630 in electricity per year.
• A SEER 25 unit will produce 60% in energy savings per year and consume around $529 in electricity per year.

 

What does SEER have to do with MPG?

It’s important to note that an AC unit’s SEER rating represents the maximum efficiency of that particular unit. This means that an AC unit with a SEER 22 rating can reach an efficiency level as high as 22, but may not always operate at a 22. So, just like Miles Per Gallon (MPG), which is used to measure the gas efficiency of a car, the higher the MPG rating, the more miles per gallon you can get out of it; but only when it’s being driven under ideal travel conditions (good weather, safe speeds, level ground, etc.). If, on the other hand, you drive your 36 MPG rated car like one of the characters from the Fast and the Furious, then your car’s average MPG number will be much lower, perhaps in the 20s.

There are things you can do to help your AC unit run at its most efficient rating, such as maintaining a regular temperature in your home, keeping the air filters clean, and checking for leaks in the ductwork.

 

Benefits and Regulation

Created and regulated by the Department of Energy in 2008, the SEER rating helps consumers cut down on energy consumption and costs while providing better cooling for their home. Also, by raising the minimum SEER rating across the U.S., the depletion of natural resources will be reduced as will the emission of harmful gases into the environment. It is required by law that all central air conditioning units be evaluated, rated, and assigned a SEER number by the manufacturer in accordance with efficiency tests stipulated by the U.S. Department of Energy.

 

FTC and the US Department of Energy

In 2015, the DOE established new minimum efficiency ratings for three different portions of the U.S. – the North, the South, and the Southwest. For new central air conditioners manufactured and sold in the warmer, southern regions, the minimum SEER was raised to 14. For northern regions, the minimum remains a SEER 13. The standard SEER breakdown across the nation is as follows:

SEER 13 minimum: Alaska, Colorado, Connecticut, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota, Missouri, Montana, New Hampshire, New Jersey, New York, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, Washington, West Virginia, Wisconsin and Wyoming

SEER 14 minimum: Alabama, Arizona, Arkansas, California, Delaware, Florida, Georgia, Hawaii, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Nevada, New Mexico, Oklahoma, South Carolina, Tennessee, Texas, and Virginia.

It is not required that consumers immediately upgrade to a more efficient unit, rather the minimum rating only applies to new units being manufactured and sold in the U.S. after January 2015.

Also, the Federal Trade Commission’s EnergyGuide label (the yellow “hang tag” attached to heating and cooling systems), will now display a range of numbers representing the lowest and highest SEER rating for split-system air conditioners, instead of a single rating.

 

Types of AC

Now that you know about SEER and EER ratings and how they relate to an AC unit’s efficiency, understanding the different types of air conditioning systems available will help you decide which option is the best one for your home.

Window Units: Also known as “room air conditioners,” this type of system contains all the necessary AC components (compressor, condenser, evaporator, and cooling coil) into a single box that is placed either in a window or wall of a room. Blowing cool air directly into a room, this type of system is effective for cooling small spaces and homes. Window units only have an EER rating.

Central Air Conditioners: Distributing cooled air via a system of ducts, Central AC systems work best for larger homes and buildings.The two most common types of Central Air Conditioning systems are split or packaged units.

Split systems: A split system has an indoor component, which includes the evaporator coil and blower, and an outdoor component, which includes the condenser coils, condensing fan, and the compressor housed in a metal case. This type of system is economical because it shares the ductwork used by the heating system.

Packaged units: A packaged unit is usually located outdoors and combines the evaporator coil, condenser, and compressor into a single cabinet. Air is drawn from the inside through ducts in the wall or roof and returned, cooled, to the inside of the house. Packaged units also typically include heating coils eliminating the need for a separate indoor furnace.

Ductless Mini-Split Systems: Ideal for houses with no ductwork, the mini-split system uses tubing to combine the outside compressor and condenser to indoor air-handling units, which are typically mounted high on a room’s interior wall and circulates the cooled air with a fan. Each room, however, will have its own air handler, much like a window unit, with the ability to cool a room to a temperature different from other surrounding rooms.

When determining the type of air conditioning system for your home, it’s important you choose a system that’s best fits the size of your home. A system that is too large or too small will not adequately cool or dehumidify your home.

What Is A Condenser On An AC Unit?

An air conditioning unit has several vital components in it that work together to maintain a comfortable temperature inside the property. If all of these components are of good quality, you can trust your system to deliver a good performance. That’s why it’s a good idea to investigate how air conditioning units work and understand the function and purpose of every component. There are four essential components in an air conditioning unit and they are compressor, condenser, meter, and evaporator. All of them work together to ensure the temperature inside your property is cool and comfortable.

What is a Condenser?

A condenser is a component that turns heated and pressurized refrigerant vapor into a cool liquid. This conditioned liquid runs through the air conditioning system and helps cool the indoor temperatures. It also soaks up the heat drawn from the room and transports it back to condenser. Without a good quality condenser, your air conditioning unit won’t cool your property efficiently.

Different Types of Air Conditioner Condenser

AC condensers come in different shapes and forms. Some perform better than others but require a higher upfront investment. Here’s a brief introduction to the options available to you:

1. Air Cooled Condenser

Air cooled condensers are common in residential applications because they’re quite affordable and efficient for cooling small spaces. They’re relatively easy to install and maintain as well, which makes them very appealing to homeowners and small business owners. Here are some of the primary components of it:

•    Condenser Fan Blade – Air cooled condensers draw air from the outdoors and use it to reject heat trapped in the superheated refrigerant vapor. The condenser fan pulls the outside air in and blows it out the heated air.

•    Condenser Motor – The motor is responsible for the fan. It will control the fan’s speed and operation to ensure it blows the air over the coils at the right time and for the right duration.

•    Condenser Coils – They are the most important aspects of the condenser unit. These coils are made from copper, which is a great heat conducting metal. The system pushes the refrigerant through the coils and ensures the vapor cools down to a liquid form.

•    Compressor – Most air-cooled condensers have the compressor in the casing. This saves a lot of space and makes the unit smaller. Unfortunately, that comes at the cost of efficiency. These units take more power and time to cool the refrigerant compared to the other options available in the market.

There are two types of air cooled condensers available in the market and both have their advantages and disadvantages.

•    Fin and Tube Condensers

•    Plate Condensers

2. Water Cooled Condenser

Water cooled condensers are more popular in commercial and industrial applications because they can cool large areas efficiently and consume relatively low amount of electricity. They’re considered more energy-efficient but they have a higher upfront cost and the installation process is a little more complicated as well.

Water is naturally cooler than the air around the AC unit, which helps with the heat transfer process. This system operates at a much lower condensing temperature so it takes less time to cool and consumes very little energy. However, there are some disadvantages of this system as well. You need to have regular supply of water in order for the system to work. You also need to make sure the water is clean and non-corrosive. It should also be of a specific temperature to ensure the refrigerant cools effectively.

Water cooled condenser units are much more likely to develop pitting, algae, mold, scaling, mineral deposits, etc. All of these factors can compromise the efficiency of the system.

•    Tube-within-a-tube – This is one of the most commonly used water-cooled condenser systems because it’s very easy to manufacture. That makes the appliance affordable as well. The double tube design consists of a small tube within larger tube. The small coil carries cool water while the larger tube surrounding it carries the vapor refrigerant. The water and refrigerant run in opposite directions to ensure the latter is cooled effectively. The water draws heat away from the refrigerant and the air conditioning unit and discards it outside.

•    Shell and Coil – This is also a very commonly used condenser system though it’s not as efficient as the double tube system. It consists of a metal shell and a copper coil. This coil contains the cool water while the shell houses the refrigerant. The superheated vapor floods the shell as the system runs cold water through the coils. This process brings the temperature of the vapor down and turns it into a liquid. Unfortunately, shell and coil systems aren’t easy to clean and maintain you need to use chemical agents to flush the debris out of the shell. No matter how clean the water is, it will leave behind some mineral deposits and they need to be removed for the system to work efficiently.

•    Shell and Tube – This is one of the most effective water cooling condenser designs. It consists of several copper tubes placed inside a steel shell casing. These tubes contain the cool water that reduces the temperature of the refrigerant. This unit can be taken apart to clean so it’s easy to maintain. The repair technician can simply remove the shell and clean the coils manually without the need for any mineral and debris deposits.

3. Evaporative Condenser

The evaporative condenser is a combination of air and water cool condensing systems. It’s not as efficient as water cooled condensers but it is a good option for large-scale cooling requirements. Here’s a brief introduction to how these systems work:

•    The superheated vapor from the compressor is circulated through the coils in the system.

•    The water present in the container wets these copper tubes and partially cools the refrigerant inside.

•    The coils emerge from the water container and are exposed to cool air, which causes some of the water on the coils to evaporate. That also works to cool the refrigerant inside until it’s in liquid form and ideal.

There are several advantages of this system that can make it worth the high initial investment. You save a lot of water and don’t have to deal with the common problems of water cooled condensing systems like scaling, mineral build-up, and algae build-up, etc. As the water evaporates as it’s exposed to the air, there’s little to no mineral deposit present on the coils. This system is quite efficient for large-scale industrial appliances and is almost always installed in big commercial buildings and factories.

Evaporator condensers come in two different forms; combined flow and counter flow. In combined flow systems, both the fill surface and condensing coils are used together. The air moves in from the upward direction and passes through the water. The combined flow of both air and water cools the refrigerant and pushes the heat towards the bottom of the tank.

In the counter system, the water moves from the upward direction towards the bottom while the air moves from the bottom to the upward direction. The direction of the flow of water and air is handled by the fans controlled by an external motor. These systems can have two different kinds of fans. The centrifugal fans are considered more efficient because they’re quieter, suitable for both indoor and outdoor applications, and offer compensation for external static. Axial fans require less energy to operate so if cost savings are a concern, you should choose a system with these fans. They’re less efficient and louder than the centrifugal fans because they have large blades that move vigorously through the air. Evaporator systems are a little more complex and sophisticated compared to water cooled and air cooled systems, which is why they’re often used in large scale applications.

You can also use earth cooled condensers but they’re known to be less reliable and more expensive. They’re not easily available in the market so if you have room in your budget, you should consider water cooled systems. They offer the most value for money, especially if you intend to use them to cool large areas.

Detailed Explanation of How the Condenser Works

As explained before, the condenser is responsible for the heat exchange and cools the refrigerant vapor until it’s in liquid form. This is where most of the heat exchange takes place. Here’s a more in-depth explanation of how the condenser works:

•    The primary function of the condenser is to turn the gaseous refrigerant vapor into a cool liquid. When the superheated, high-pressure vapor arrives at the condenser, its passes through narrow condenser coils.

•    At this stage, the blowers blow cool air over the coils to forcefully lower the temperature of superheated vapor. During this process, the vapor turns to high pressure liquid and rejects heat. In water cooled systems, the vapor is cooled by water.

•    The rejected heat is expelled from the air conditioning unit and you can feel the temperature if you place your hand in front of the blow in the external air conditioning unit.

•    The conditioned liquid is transported to the meter and then to the evaporator. In the evaporator, it’s circulated through the coils as a fan blows air past them. This cools the blowing air and helps cool the indoor environment. During this time, the refrigerant reabsorbs the heat from the room and turns back into the vapor state.

This cycle happens repeatedly when the air conditioner is switched on. This entire process is the transfer of heat from your indoor space to the outdoor space.

How Do Air Conditioning Units Work

All components of the air conditioning system play a vital part in this process. For the heat transfer to happen successfully, the unit must follow the laws of thermodynamics. The temperature of the refrigerant should be higher than the temperature of the environment. Here’s a brief glimpse into how it happens:

•    Cooled Refrigerant in the Evaporator – The evaporator component is closest to your indoor environment. The cooled refrigerant liquid passes through the evaporator coils as the fan in the unit blows air past the coils. The air blowing past the coils is quite cool and will bring the temperature of the room down to comfortable levels. The cold liquid will also draw the heat from the room and slowly absorb it. The refrigerant is very reactive and when it’s subject to heat, it quickly turns into the vapor form and moves on. This gives room for newly cooled liquid refrigerant to enter the evaporator once again.

•    Warm Refrigerant Vapor in the Compressor – The vapor travels to the compressor and moves through increasingly smaller tubes. This applies pressure and increases the temperature of the refrigerant vapor until it’s superhot and pressurized. If the compressor doesn’t force the refrigerant to become superhot, the condenser won’t be able to reject the heat and transfer it to the surrounding environment. Heat only transfers from high intensity environments to low intensity environments as per the laws of thermodynamics. If the temperature of the refrigerant is lower than the surrounding temperature of the environment, the condenser won’t work.

•    Heat Rejection in the Condenser – As explained above, water, air, or other components in the condenser draw the heat away from the refrigerant vapor and eject it. This cools the refrigerant and turns it back to a liquid form. The temperature of the refrigerant entering the condenser can be 90 to 105°F higher than the temperature of the surrounding areas. If you touch the copper tubes that carry this vapor, you’ll burn your hand.

•    Controlling Speed and Pressure through the Meter – The meter is simply a checking mechanism that controls the speed at which the refrigerant liquid travels through the system. If the refrigerant travels too quickly through the system, the AC won’t cool the room efficiently. It directs the cooled air to the evaporator and the whole cycle begins once again.

Things to Consider Before You Shop for Condensers in Air Conditioning Units

As you might have noticed, air conditioning units rely heavily on the efficiency of the condensers. However, you don’t need the most sophisticated system available in the market in order to get the cooling you need. Here are some considerations you need to keep in mind before you purchase any appliance air conditioning appliance:

•    Small Areas and Limited Budget – ACs with air cooled condensing systems work efficiently for up to 2 tons. If you just want to cool a small office or a comfortably sized room, you don’t need to invest in the more expensive systems. These air conditioners will work just as you expect them do and deliver a reliable performance. They’ll have a slightly shorter lifespan and the compressor is likely to give up quicker, but the initial investment is quite low so it’s suitable for residential and small commercial applications. Your AC unit will comfortably last for several years.

•    Large Areas – If you want to cool a large house, a small commercial store or shop, or an office floor or building, you should consider AC units with water cooled condensing systems. They’re more efficient and offer better cooling with low energy consumption. In large properties, power consumption is a big concern and inefficient system can add to your monthly expenses. These AC units are worth the larger initial investment because you’ll save a lot of money in the long run. Unfortunately, water cooled systems do require more maintenance so you’ll have to hire a professional to clean, repair, and maintain your air conditioning unit at least twice a year.

•    Big Buildings – Air conditioners with evaporator condensers are a good option for large properties like factories, big office buildings, etc. They consume less power and utilize less electricity. They don’t cool as efficiently as water cooled condensers, but the long-term benefits make them a good choice. They require specialized installation and a lot of space so if you’re on a tight budget and don’t have space to spare on your property, this might not be an option for you.

So if you’re in the market for a new air conditioning unit, you need to consider your budget, the size of the space you need to cool, the amount of outdoor space available, maintenance expenses, power and water bills, cooling capacity, etc. Once you understand your requirements, you’ll have an easier time with the number of options available in the market.

If you understand how the air conditioning unit works and know what role each component of the system plays, you’ll be able to make the right decision during the time of the purchase. If you’re still uncertain, it’s a good idea to ask a professional for advice. They’ll consider your personal requirements and budget before they recommend an air conditioning system that works well for you. They’ll also be more familiar with the popular appliances available in the market.

How Do I Reset My Air Conditioning Unit?

An air conditioning system works to keep your home environment comfortable and cool during hot weather. Like most appliances, this system is prone to problems as well, and sometimes doesn’t function as well as you expect it to. Most people instinctively call the air conditioning repair service provider when they face problems with their unit. But there are some steps you can take to resolve the problem on your own. For example, if your A/C replacement isn’t functioning as you expected it to after a power outage, you can try resetting it.

Why Do You Need to Reset?

You need to reset the air conditioner because the circuit breaker is engaged and isn’t allowing the compressor to start. The circuit breaker will pop if there’s a surge in power supply or if there’s a sudden black-out or brown-out. This part of the system works to protect the air conditioning unit and prevent problems like fires and explosions. The circuit breaker is an essential component of any unit and shouldn’t be bypassed. You might also need to reset your whole air conditioning unit if the thermostat is malfunctioning and isn’t set to cool.

How Do You Reset the Air Conditioning System?

Before you attempt to reset the air conditioner, ensure that you have regular power supply and the current is flowing uniformly. If you have experienced a recent brown-out, switch on a light and check the brightness to ensure you’re receiving full power. Once you’re certain, you can move on and reset the unit. Here’s what you need to do:

Find the Reset Button – Many air conditioning units will have a reset button on them. The button is usually red in color and fairly small in size. It should be marked clearly as a reset button. You can consult the instructions manual to determine if your air conditioning unit has that button, and find its location.

Press The Button – Once you find the button, press it continuously for 3 seconds and release it. After a few moments, press the button again for 3 seconds. Your air conditioning unit will respond with three beeps. The system should be reset immediately.

If your AC Doesn’t Have a Reset Button

If your air conditioner doesn’t have a reset button, you need to reset it manually. That doesn’t take too much time or effort. Manual reset isn’t complicated, and all you need to do is follow the steps mentioned below:

• Shut the Power Supply Off – There should be a shut off panel next to your outdoor compressor unit. The main AC wire will be plugged into this unit and it will always be switched on in normal circumstances. Flip the switch off and move on to locate the 240-volt circuit in the main electrical panel in your home. You need to switch that off as well. That will completely cut all power supply to your air conditioning unit.
  
• Unplug – Just as an added precaution to ensure the AC unit is completely off the grid, unplug it from the power supply board and disconnect the system.
• Wait for 30 Minutes – You don’t have to wait too long to reconnect the system but it’s a good idea not to reconnect it too quickly either.  You need to make sure all the lingering charge in the system dissipates before you reconnect the air conditioner back to the power grid. 30 minutes is enough time for the internal systems to reset completely.

  Plug it In – Plug the system in after a few moments have passed. You don’t need to switch the air conditioner back on immediately at this point.

  Switch on the Power Supply – Once the air conditioner is connected, go back to the main 240-volt switchboard and switch it on. Then come back to the plug point near the external unit and switch it on. Make sure your thermostat is set to “cool” before you switch the power on completely.

If you follow these steps, your air conditioner will work as you expect it to. If your air conditioner still doesn’t cool effectively, try to check the thermostat and clean the filter. Dirty filters can obstruct airflow and compromise the cooling efficiency of the machine. Once the thermostat is on the right setting and the filter is clean, run the air conditioner once again to test if it cools effectively.

When Do You Need to Call a Professional?

You need to call a professional if your air conditioning unit’s circuit breaker keeps tripping and is slow to cooling down. This is an indication of a more severe problem that should be addressed quickly. You should also call a professional if the breaker panel doesn’t have its protective covering and wires leading up to the outdoor compressor unit are exposed.

If you reset the air conditioner in such conditions, you’ll put your safety at risk. Exposed wires can create sparks and cause fires. A loose connection or exposed wire inside the system can also cause surge in the power and trip the circuit breaker often. These surges can damage the air conditioning unit permanently and force you to purchase an AC replacement.

You can’t keep resetting your air conditioner repeatedly without causing problems to the system. A professional will examine your air conditioner carefully and determine why it needs to be reset so often. They will also check the refrigerant levels, examine the compressor, and clean all fans and filters.

Regular Maintenance is Important

You should also maintain your air conditioning unit regularly to ensure it functions without interruption. A poorly maintained air conditioner will develop problems more frequently. Experts recommend that you get your unit serviced at least once in a year.

The service technician will spot any frayed and damaged wires and replace them. That will decrease the likelihood of the air conditioner’s circuit breaker tripping or the unit not cooling efficiently. You can also do some at-home maintenance by cleaning the filter regularly as well.

Furnace & Air Conditioner Size For 2-Story Home

A furnace or an air conditioner for your 2-story home represents a significant investment and this makes it important to buy systems of the right size. Not only will it work more efficiently, but will be able to maintain a comfortable indoor atmosphere. It’s crucial to keep in view that if an air conditioner is too large, it will use an excess amount of electricity and the air in your house will also feel too cold and clammy. On the other hand, if the air conditioner is too small, it won’t be able to keep your indoor temperatures at comfortable levels. If you want to choose the right size of air-conditioning system, you’d have to follow some basic math.

Aspects to consider

Regardless of the number of stories your home has, the air conditioner or furnace size would be dependent on the total square footage that has to be cooled. A number of other factors also come into play when estimating the size of either a furnace or AC system, such as:

• • The amount of exposure to the sun & the outdoor air
  • Type of outer wall insulation
  • Thickness of the insulation
  • The type, size & number of exterior doors and windows
  • Ceiling height
  • Other

   

• Effects of undersizing or oversizing your furnace or air conditioner

  As mentioned earlier, oversizing or undersizing can impact the efficiency and performance of the system and will affect the comfort levels in your home, regardless of whether you are getting a furnace or an AC installed. Undersizing results in the system being unable to meet the required temperature settings. Aside from the comfort aspect, when you undersize your AC or furnace system, that can most likely lead to a premature failure of the units.

• Most people are also under the misconception that larger units will also be more efficient and provide more cooling; but as discussed at the outset, this is a misconception. When we talk about the heating ability of a furnace or the cooling ability of an air conditioning unit, uniform distribution is of utmost importance and that becomes the optimum operational time of the system. When you opt for oversized units, they may be able to cool your home much quicker, but it won’t run for the optimum length of that cycle and will not provide a uniform temperature in your 2-story home. This means you will notice that there are cold and hot spots across your home.
• When you use an oversized furnace that can cause the system to get stressed and overheated. The ducting network that exists on your property would be unable to support the large air flow volume, which will result in a pressure buildup within the return air duct and cause the furnace to overheat. In addition to erratic air distribution, when you oversize your air conditioner that results in higher humidity levels in your home. Air-conditioners are meant to dehumidify the air as well as cool the indoor spaces. The indoor evaporator coil removes water vapor and moisture from the air that’s passing through. If your property has an oversized air-conditioner, it will cycle faster and won’t be effective in dehumidifying the air to the right levels. The other factor to keep in view is the energy-efficiency of the system.
• The furnace or the air conditioner can provide optimal efficiency only when it has been sized correctly. When you either oversize or undersize your furnace or air conditioner, it impacts the energy-efficiency and you will be saddled with higher utility bills.

• One Unit or Two?

  This is one more question you should be asking yourself. If you live in a 2-story home, a single Ac unit might not be able to cut it. If you set the thermostat to a lower temperature to offset the warming that occurs naturally in the living spaces on the upper stories, that can cause the lower floors to become chilly and vice versa. The best way to solve the problem is to install 2 separate units, each dedicated to one level. While you do end up paying a higher upfront cost as well as operating and maintenance costs, you would be able to control the cooling or heating on the different levels more effectively. These 2 smaller units will perform the job of a single larger unit, but in a more effective way.

  The additional cost of the 2nd unit may easily be offset by sizeable energy savings in the long term. A lot of this depends on how the structure of your house is and the manner in which you use your air-conditioners. There is another distinct advantage to getting 2 units installed in your two-story home. In case there is a downtime on one system, you might just be able to maintain a certain level of cooling in the house till the time you get the dysfunctional one fixed.

  Install A Good Zoning System

  If you prefer to install a single AC system, you should consider zoning. When you divide the system into various zones that have individual thermostats, it adds to the cooling or heating capacity of the unit. The motorized dampers within the ductwork respond to the signals from the system’s central controller to direct the cool air to one zone when it reaches the temperature set on that specific thermostat.

  It will simultaneously decrease/shut down the air-flow to another zone which doesn’t need that level of cooling. A zone dampener opens and closes independent of other similar systems that are installed on the property. This allows a single AC to effectively maintain the temperature in the lower and upper floors. You have the option to turn off the cooling or heating zone on one story while the system heats only the zone/s that is being using. This functionality also makes a zoned furnace or AC system extremely cost-efficient.

  As you can see, there are a number of variables that come into the picture when you are purchasing a furnace or air conditioner for your 2-story home. This means you would have to hire the services of a professional installer to estimate what type of system would work best for your needs.

   

How Can I Choose an Air Conditioner?

Choosing the right air conditioner can be a challenge because there are many products available in the market today. You have to research different brands, cooling capacities, energy star ratings, performance reviews, and other such factors before you make your decision. The entire process can be a bit daunting so most people just settle for the first product that they find with good ratings, and call it a day.

Most end up regretting their hasty purchase when the energy bills start to flow in. If you want to choose a good air conditioner, you should spend some time on research or ask for assistance from a professional. We’ve put together a comprehensive guide to help you choose an air conditioner that’s perfectly suited for your requirements.

What Factors Do you Need to Consider?

Before you shop for air conditioners, make sure you have a list of factors to consider. These factors will help you understand if the appliance is suitable for your needs. Here’s a list of factors you should take into account:

•    Consider the Noise – Many people don’t consider the air conditioning unit’s potential for causing noise. Most modern ACs are quieter and more comfortable, but they still make some noise and that can disturb light sleepers. If that’s a concern for you, you should check how much noise the air conditioning unit generates. You should also consider the different types of air conditioners carefully if you’re particularly sensitive to noise.

•    Look for Intelligent Cooling Options – Modern air conditioning units come with smart cooling options. You can interconnect different air conditioning systems in your home, access the unit remotely through your mobile phone, set timers to automatically switch the AC unit off or on, etc. This will help you conserve energy and get the most out your unit. For example, you might be able to remotely switch your AC off if you forget to before you left your home.

•    Consider the Warranty – All household appliances require maintenance and can develop problems. Air conditioners are no exception to this rule and can develop problems, which is why you should consider the warranty carefully. You can check the manufacturer’s website for all warranty information or ask the retailer for advice. They’ll list the brands with the best warranties and customer service available.

•    The Filter Position Matters – The filter collects dust and debris over time. This can block the air flow and compromise the quality of air in your home. Fortunately, it’s very easy to clean filters as you just need to remove them and brush the accumulated dust away. Unfortunately, some air conditioning units don’t have easily accessible filters so you need to call in professionals to clean them every time. Before you purchase an AC, be sure to check you can clean it well.

•    Where you Intend to Install – Most window and split units will blow cooled air in one particular direction so it’s important to consider where you intend to install the unit. Window ACs can only be installed in windows so you need to consider the location of the window and determine if the unit will blow air to the center of the room. If you intend to install a split unit, you need to consider it’s placement on the wall before you make the purchase.

•    Budget – Your budget is the ultimate deciding factor and will help you narrow down the list of products. Make sure you set a firm budget in advance before you search for air conditioning products online or in stores.

Determine the Size of the Unit You Will Need

The next step is to determine the size of the unit you will need for your room. If you purchase a unit that’s too big, your room will cool unevenly, the AC will consume more power, and the compressor will cycle too often. If your AC unit is too small, the compressor will have to struggle to maintain the set temperature and will remain switched on for a long time. That would also lead to increased utility bills.

So how do you determine what size you need for your room? You can ask an experienced retailer or call a professional to assess your property and offer recommendations. However, if you want to determine the capacity you need yourself, you should look at the points mentioned below:

•    The Size of the Room ¬– Every square foot of your room requires 20BTUs or British Thermal Units. If your room is 300sq feet, you’ll need an air conditioning unit that provides at least 6,000 BTUs. You can measure the room area by multiplying the length and width of the space. This will help you establish a baseline but there are other factors you need to consider as well.

•    The Number of Windows and Doors – The number and size of your doors and windows is also an important factor in this calculation. Doors and windows are leak points. They let the conditioned air out and bring the hot air in. No matter how well they’re sealed, some of the air will slip past them. You also need to factor in just how much light seeps into the room through those doors and windows. If your room is very bright and sunny, you need to increase the estimated BTU amount by 10%. To follow the previous example, you’ll need an air conditioning unit of at least 6,600BTUs for bright and sunny rooms. You can lower the BTU amount by the same percentage if the room is dark and shaded.

•    The Height of the Ceiling – You would also have to consider the height of the ceiling when you shop for an AC unit. If you have tall ceilings, the air conditioner will have to cool a larger area. You need unit of slightly higher capacity.

•    Where You Intend to Place the Unit – Your air conditioning unit should direct air towards the center of the room for maximum effectiveness. If you’re forced to place the unit in a corner and away from the center of the room, you might need to invest in ACs with higher cooling capacities. We recommend that you add a fan in order to circulate the air comfortably throughout the room.

•    Number of People – People generate body heat and that increases the temperature of the room just by breathing out warm air. If a room is usually occupied by 2 to 3 people, you should increase the BTUs count by 600 units per person. In the example mentioned above, you need increase the BTU count to 7,200 units if you add another person to the room.

•    Kitchen – the kitchen environment is very warm and your air conditioning unit will need to work more to maintain a comfortable temperature. The AC should compensate for the heat emitted by kitchen appliances like stoves, ovens, refrigerators, etc. We recommend that you increase the BTU account by 4,000 in if you intend to install an air conditioning unit in your kitchen.

How to Choose the Right Model?

It can be tempting to save money and purchase a small window air conditioning unit. Unfortunately, that can have consequences in the long run because you have to deal with higher energy bills and a short unit lifespan. You can enjoy lower ownership costs by paying a little more money up front. There are a number of options available to you in the market so you don’t have to spend more than you can to get a good unit that fits your requirements perfectly.

1. Window Air Conditioners

Window air conditioners are ideal for smaller rooms and offices. They’re available in different sizes and capacities as well. Here’s a small introduction to your options:

•    Small Window Units – Small window units are the most affordable air conditioners available in the market. They’re light-weight, discreet, and usually don’t make much noise. They don’t consume as much energy so the cost of ownership is low as well. However, smaller units can only effectively cool around 100 to 300 sq feet of space easily. They’re not ideal for bigger rooms as they provide only 5,000 to 6,500BTUs/hr and that’s insufficient for larger rooms.

•    Medium Sized Window Units – Medium sized window units can easily cool rooms ranging from 250sq feet to 400sq feet in size. These appliances provide 7,000 to 8,200BTUs/hr and are slightly more expensive compared to the smaller units. They also consume more electricity and are more difficult to install. These units are bigger in size and heavier than small air conditioners.

•    Large Air Conditioning Units – Larger air conditioning units provide 9,800 to 12,500 BTUs/hr and can easily cool around 350sq feet to 650sq feet of space. Unfortunately, they’re also the most expensive air conditioning units in this category. They’re also very heavy and bulky, which is why most people hesitate to install them in their homes. The weight and bulk can make installation and repairs difficult and expensive. These units also compromise the overall aesthetics and beauty of your home.

2. Portable Air Conditioners

If your home’s architecture or building regulations prevent you from installing regular air conditioners, portable air conditioners will be a great option for you. However, before you invest in these appliances, pay attention to their performance and effectiveness. Here are some things you need to know about portable air conditioners:

•    They provide cooling within the range of 5,000 to 15,500 BTUs. That’s enough to cool a good sized room or office easily.

•    Unfortunately, portable units don’t perform as well as regular air conditioning systems. You will need a unit of higher capacity and BTUs rating to cool the required amount of space.

•    Portable units aren’t as energy efficient and will consume more electricity. You will have to spend more money on them in the long run.

•    These units are also noisier that traditional window units, which can be a big disadvantage to light sleepers.

•    Portable air conditioning units are quite big and visible so they stand out like a sore thumb on your room. They’re also very heavy and difficult to move around.

As you can see, portable units aren’t very portable or affordable. However, they’re a good option if you intend to move regularly or can’t install other air conditioning systems in your home.

3. Split Ductless Air Conditioners

Split units are a great way to condition the air in a small number of rooms at the same time. You don’t need to install a separate duct systems or invest in a central air conditioning. These units deliver a reliable performance and are easy to maintain as well. You will have to invest in a professional installation, but split units are generally considered to be a better alternative to the two air conditioning systems mentioned above. Here are some of the biggest advantages of split units:

•    They’re excellent at cooling and will maintain a comfortable temperature in two or more rooms. This depends largely on the capacity of the compressor unit. Smaller units can only cool smaller rooms.

•    They’re quieter than window or portable air conditioners because the compressor unit is separate and located away from the room. You’ll only hear the faint noise of the fan blowing and air circulating through the system and the room. This unit is ideal for light sleepers who can’t bear the excess noise of window air conditioning units.

•    They require a higher initial investment. Most units cost more than $1,000 and you need to spend some money on a professional installation as well. However, they do consume less energy so you will save money in the long run. Split units are also more durable and come with better warranties.

•    While split units will cool a couple of rooms easily, they won’t cool the entire house. If you need air conditioning in a large space, you should consider investing in central units.

If you have room in your budget and want something that will deliver a reliable performance, split units are your best bet.

Special Features in Modern Air Conditioning Units

Modern air conditioning systems provide a number of features and settings that can help you save money on electricity bills and keep the internal environment comfortable. Before you purchase the system, consider these features carefully:

•    Controls – Most modern air conditioning systems come with on-appliance and remote controls. These controls help you adjust how the air conditioning system works. Poor quality controls can be a constant annoyance and hamper your user experience. Make sure all buttons are easy to use and all controls work as you expect them to.

•    Direction of Air Flow – The conditioned air should reach the center of the room and circulate around to ensure all areas of the space are cool and comfortable. Check the controls to see how the unit manages air flow. Most air conditioning units allow you to control the direction and speed of the air flow and that has an impact level of cooling.

•    Energy Saving Features – Air conditioning units provide energy saving features like timers, automatic shut offs, scheduled operation, etc. These features will help you keep your indoor environment comfortable without consuming too much energy.

•    Dehumidifying – Some air conditioners also have dehumidifying capabilities and can remove excess moisture from your room. You won’t have to invest in a separate dehumidifier to maintain a comfortable environment in your home.

•    Ventilation Without Cooling – This feature ensures your room doesn’t feel stale. The air conditioner can take the stale air from the room and circulate fresh air from outside. This improves the overall quality of the indoor air.

The Brands Available in the Market

There are several brands available in the market and most of them have a large product range as well. Here’s a brief introduction to all of these brands:

•    Friedrich – This brand manufactures high quality window air conditioners that deliver a reliable performance. These air conditioners are a little more expensive compared to the products available today, but they’re all Energy Star certified,

•    Frigidaire –They have air conditioners ranging from 5,000BTUs to 25,000BTUs so you will definitely find something that suits your requirements. These air conditioning units generally have a good reputation.

•    GE – GE is a well-known and well-established brand with a wide range of products. They also sell air conditioning units with 5,000BTUs to 25,000BTUs and all their products are energy star certified.

•    Haier – Haier has some highly rated and popular air conditioning products in the market. They offer units that provide 5,000BTUs to 24,000BTUs and all their products are also Energy Star rated.

•    LG – LG manufactures a number of high quality household appliances and has a large collection as well. The units provide BTUs ranging from 5,000 to 25,000 as well.

Taking all these factors into consideration might seem like a lot of work, but you will have a great air conditioning system in your home as a result.

How To Buy an Air Conditioner

What is a BTU in Air Conditioning?

If you want to cool your home efficiently, you need to choose an air conditioning system of the right capacity. If you make the wrong choice, you might end up spending more money on energy bills. If you choose an air conditioner of lower capacity, your room won’t be sufficiently cool or comfortable. Most people don’t understand how heating and cooling systems work. They look at the technical information provided in the user manual or product description but don’t really consider what those technical terms mean. One of those technical terms is BTU.

What is BTU?

BTU stands for British Thermal Unit and it’s used to assess how much thermal energy an appliance can generate. One BTU unit equals the amount of energy a system needs to raise the temperature of one pound of water by 1°F if it’s at sea level.

You might wonder how this relates to air conditioning as ACs are used to lower the room temperature instead of increasing it. In air conditioners, this unit of measurement is used to determine how much heat the appliance can remove from the air in the room every hour of use. The BTU is directly proportional to the cooling power of your appliance. Most customers skip past this unit of measurement when they look for suitable air conditioners and that can be a mistake. You should consider BTU carefully before you think of an AC replacement.

Does Higher BTU Mean it’s Better?

It’s important to find just the right amount of BTU’s for your requirements. Too many or too few BTUs can cause problems in the long run and damage your air conditioner. If the BTU is too high, your room will cool too quickly and that can cause the air conditioner to cycle more often. That places a considerable amount of load on the compressor and can shorten the lifespan of the air conditioning unit.

Air conditioners with higher BTUs can also consume more energy and that can have an impact on your monthly expenses. If you want to extend the lifespan of your air conditioner and ensure you don’t spend too much on energy bills, make sure you opt for a system with the right amount of BTU’s. You can consult with experts like installers or store owners to determine just how many BTU’s you might need.

What Happens if You Purchase a System with Insufficient BTU’s?

If your air conditioner has lower BTU’s, it won’t cool your room enough and you’ll never attain the level of comfort you need. But that’s not the only consequence of insufficient BTU’s. The struggle to reach the desired temperature will place an excessive load on the air conditioning unit and can cause problems in the long run. Eventually, the compressor will buckle under the pressure from the heat generated, and you’ll have to replace the unit entirely. If your air conditioner doesn’t cool efficiently enough to reach the set temperature, it won’t cycle at all. That means that it will consume excess energy and you’ll have to deal with higher electricity bills every month.

How Many BTU’s Do You Need?

It’s a good idea to ask an expert to measure your home or assess your requirements and offer recommendations. They’ll make sure you get the right unit for your requirements. You can also use online calculators to determine the right size. Most wholesale air conditioner vendors will have calculators or recommendations listed on their website. However, here’s a general recommendation that can help you determine how many BTU’s you need to cool your room or office based on their size in square feet.

•    Areas between 150 sq. ft to 350 sq. ft – 5,000 to 8,000 BTU
•    Areas between 400 sq. ft to 700 sq. ft – 9,000 to 14,000 BTU
•    Areas between 1000 sq. ft to 1600 sq. ft – 18,000 to 25,000 BTU
•    Areas between 1900 sq. ft to 2700 sq. ft – 28,000 to 36,000 BTU

There are several other factors to consider; so just going by the room size will not lead you to the most efficient system. You need to consider the number of rooms, windows, and other such factors as well. For example, if you have too many windows that let ample sunlight in, your air conditioner will have to work harder to get the desired result. In such cases, you’ll benefit from a unit with a higher BTU measurement.

If you want to install air conditioners in hot rooms with large windows or too many heat generating appliances like a kitchen, you can add around 10% more BTUs to your estimate. You can also reduce the amount of BTUs if the area you want to cool is already relatively cool and dark like the basement.

Other Factors

You need to consider what kind of unit you want for your property. Portable and window units differ from central air conditioning systems so you need to calculate the BTU’s based on the system. Central air conditioning will require more BTUs to cool your property comfortably in many cases because they cover a large area that includes both hot and cold spots.

How to Choose the Right Air Conditioner Based on BTUs

A sales representative can help you determine the best option for you but here are some tips that can help you choose the best air conditioner for your requirements:

•    Consider the area you want to cool carefully. Measure the room, count the number of windows and doors, look for any additional heat sources, etc.

•    Determine your budget for air conditioning units and make sure there’s some room to overspend if needed.

•    Look at the technical reference charts carefully and compare the BTU’s and prices of air conditioners from different brands.

•    Look at the performance reviews of all air conditioning units in your shortlist and compare the reviews to price and BTU’s.

This will help you choose the best product for your needs. If you want professional installation and expert consultation on air conditioning systems, don’t hesitate to contact Pricefixer or call us at 877 774 2334. We’ll be happy to help.

 

How Does An Air Conditioner Work?

Most residential and commercial properties have some form of HVAC system installed and the basic principle of all of them is the same- the heat from one area is replaced with cold air while the former gets expelled from that space; typically to the outdoor atmosphere.

ACs and refrigerators function in the same way. While the latter cools the insulated space within the refrigerator, an air conditioning unit cools rooms, the entire house or even a residential or commercial structure. An air conditioner uses chemicals which easily get converted from a gaseous state to a liquid state and back in to the gaseous state. This chemical transfers heat from the indoor air into the outdoor air.

There are different types of air conditioning systems:

Central Air Conditioners Heat Pumps Evaporative Coolers Room Air Conditioners Ductless Mini-Split ACs State of the Art Cooling

Air conditioner- the working

The ambient air gets pulled over the condenser that contains the refrigerant gas. As the air moves across the system, there are 3 main stages in the working:

• The evaporator holds the sub-cooled

refrigerant

.

• The air then blows right through the network of veins and releases the cooled, dry air into the indoor spaces. The condenser hold the high-temperature gas, which moves through the network of veins, collects the heat as it moves through and then gets expelled in the outdoor air. The system contains a chemical

refrigerant

•  that absorbs all the heat and then pumps it through a network of pipes to the coil that’s positioned outdoors. The fan is located in the outdoor unit and it blows the outdoor air all over the hot coil; this transfers the heat the

refrigerant

 contains, to the outdoor environment.

The components of an air conditioner

Most replacement AC systems have 5 components:

• The condenser A

compressor

•  Evaporator coil The blower The chemical

refrigerant

A central air conditioning unit functions via a split unit; these systems have the condensing unit which is the hot side (this includes the compressor, condensing coil and the fan). This entire unit is installed in the outdoor spaces of your home.

The other unit which is the cold side is positioned in the indoor spaces of your home. This unit is made up of the cold coil and the expansion valve; this is typically a part of an air handler like a furnace. It blows air right through the evaporator coil that cools the air. The cold air then gets circulated across all the spaces in your home via a network of ducting.

Functioning of a window AC

If you have a window unit, that too functions on the same principle. The only difference is that this system doesn’t have a split system and the hot and cold sides are located in a single window unit and housed within one unit.

• The thermostat controls the

compressor

• , which is the core of the AC system.  The

compressor

• ’s pumping motion causes the

refrigerant

•  to easily flow right through the system. It draws in the

refrigerant

• , which is a low-pressure and low-temperature gaseous state substance. When this gas gets compressed, it raises the

refrigerant

• ’s temperature. This high-temperature, high-pressure gas eventually flows into the

condenser coil

• . This coil is made up of a network of pipes that has a fan, which pulls in the outdoor air across the coiling. When the

refrigerant

•  passes through this coil and the cooler air from the outdoors moves through the coil, the heat from the

refrigerant

•  gets absorbed by the air. This condenses the

refrigerant

•  and turns it from a gaseous state to a liquid state. From this point, the high-temperature, high-pressure liquid finally reaches the expansion valve. The network of pipes that connects to an air–handler or furnace is the

evaporator coil

• . The air handler blows the indoor air all across this coil due to which it begins absorbing heat from the air. This cooled air then gets delivered into the house via the ducting. Post this, the

refrigerant

•  flows into the

compressor

. This cycle continues over & over & over until the indoor spaces reach the desired temperature. When the thermostat senses that the indoor temperature has reached the correct setting it turns- off the air conditioner. When the room starts to warm up, the thermostat then turns the AC back on till the room/s reaches the set temperature.

Air Conditioner Filters

The one way to ensure that your AC unit work efficiently and in a consistent manner is to ensure that its filters are either regularly replaced or cleaned.  If the filters are dirty or clogged, they will block the normal airflow and significantly impact the efficiency of the system.

When the normal airflow gets obstructed, the air which moves past the filter can get into the evaporator coil and the dirt can affect the heat-absorbing capacity of the coil. The air-conditioning system’s filters are positioned somewhere along the length of the return duct. They are commonly located in furnaces, ceilings, walls or in the AC unit itself.

Types of filters

Some air conditioning units have reusable filters while others just have to be replaced when there is too much dirt and debris trapped in them. These are also available in a number of efficiencies and types. If you want your AC system to function well, you should either replace or clean the filters at least every 1-2 months in the cooling season.

While this is the thumb rule, in case the Ac unit sees heavy use, or if it has to operate in very dusty conditions, or if you have furry pets in the house, the filter would have to be cleaned more often. If your system uses disposable type filters, it’s a good idea to keep multiple spares in your house.

When you are buying a wholesale air conditioner, you would have to take a number of aspects into account. The type of AC system you choose will be dependent on the location and size of the space to be cooled and a number of other conditions.

 

FAQs About Air Conditioning and Heating

A ductless heat pump is a very efficient and simple heating system replacement for traditional furnaces and electric heaters; it performs the functions of heating as well as cooling. A ductless system offers very easily-controlled air-conditioning and heating that can keep the temperature in the indoor spaces of your home at comfortable levels, right round the year.

What is a Ductless Heat Pump System?

This type of system is also referred to as a ductless mini-split system and is a highly-effective way of heating and cooling your home. It becomes an excellent primary HVAC system in homes that also have electric furnaces and wall heaters. A ductless heat pump system is specifically designed to provide comfort right round the year and it works noiselessly as well. Apart from that, it allows you control & efficiency even as it cuts your electric heating expenses by almost 50%.

How Does a Ductless Heating System Work?

This system functions differently from a standard electric heater, which creates its own heat. A ductless system pulls the heat from the outdoor air and uses it in heating your home. This process can be reversed within the system, to cool your home. A ductless heat pump distributes cool or warm air far more efficiently and quietly than a conventional electric heater.

Ductless Heat Pumps- The Facts

If you are looking for a furnace replacement, a ductless system is an excellent option. Most people are aware of what these systems are, and you may have also seen the indoor units installed on the walls in homes, restaurants as well as office premises. Here is some detailed information and facts about them:

1. Highly Flexible Option

A conventional heat pump & air-conditioning system forces heated and cooled air via ducts. In comparison, a ductless system delivers air directly from the indoor units, into different zones or rooms. These are typically made of an outdoor unit and one/more indoor units, depending on the cooling and heating capacity of the system. The indoor units aren’t connected to the outdoor unit via ducting. Instead they are connected via small pipes that run through a small hole in the wall to the outdoor unit. These kinds of installations make these systems a very flexible option. The indoor units only require mounting units and access to electricity.

They may also be referred to as multi-split, split or split –ductless systems and they are a very cost-efficient way to replace space heaters, electric baseboard heaters and window units that aren’t as efficient. They can be easily installed in new construction, home additions, apartments and condos and are provide you the flexibility to control the temperatures in these individual spaces. A ductless heat pump can also be installed in structures that currently use a ducted heating system.

2. Cost-Efficiency

One of the main reasons why many homeowners opt for these as their furnace replacement is because the ductless systems are highly efficient and can significantly reduce your utility bills. They consume far less power compared to other heating systems, and are more compact in size as well. Since they deliver the heated or cooled air directly in to the room, there is no loss of efficiency.

The multi-split system can also give you the flexibility to create various zones in your home and you don’t have to cool rooms which aren’t occupied. This becomes a distinct money saver. Aside from the money you save, when you install a ductless heating pump, you may also be eligible for utility rebates/tax credits for the year during which you install this system. Regardless of how you look at it, installing a ductless heating system is a win-win for you.

3. Improved Air Quality

Since we shut the windows and doors of our homes in the colder months, often times the indoor air quality is lower than the outdoor air quality. When you have a ducted system, you have to ensure the ducting is cleaned with regularity by professionals. Despite having done this, there are times when allergens and dust tend to linger in the indoor air. In comparison, a ductless system offers multi-stage filtration, which is extremely effective in reducing bacteria, dust, allergens and pollen from the air.

4. Easy and Quick Installation

It can take several weeks to install a ducted system and the work can disrupt the daily activities in your home or office. In comparison, the installation of a ductless system is far less intrusive, based on the total number of outdoor & indoor units that have to be installed. In most instances, it doesn’t take more than a day to install the system and get it running.  This means you have less hassle to deal with and don’t have to go through the inconvenience of staying without heating or cooling depending on what the outdoor climate is like.

In these systems, small pipes connect the outdoor unit with the indoor unit, and only a 3” hole is required to be made. Very simply, you don’t have to worry about any damage and rebuilding of walls and ceilings, like the kind that occurs when you get a ducted heating installed in your home or office space.

5. Environment-Friendly

Since these systems are smaller and are used to cool individual rooms or specific zones, they are very energy-efficient and the ones from the best brands always have a high-energy rating. The refrigerant used in these systems is called R410A, which is a zero-ozone depletion refrigerant. This means the ductless heating systems has a very low impact on the environment right through ‘its lifespan and it’s a great way of reducing your carbon footprint.

A ductless system is an ideal heating system replacement as well as a supplemental heating and cooling system for any other HVAC unit that is currently installed on your property. With this unit, you are assured of a comfortable indoor environment right through the year. You should discuss various options with your HVAC contractor to choose the system best –suited to your needs.

What is a Portable Air Conditioner?

A portable air conditioner is an appliance that takes in the room air and then redirects it into the room after cooling it. The warm air from the outside is vented via an exhaust pipe that you would have to install in your window. The unit has in built controls that allow you to access settings such as temperature and fan speed.

This is very versatile and simple alternative to window air-conditioners and central HVAC units. A portable air conditioner is specifically designed to cool individual rooms; it has a small footprint and is an excellent option for rooms you don’t need to be cool all the time, or those that don’t have a cooling system. In fact, they can also be used to complement any larger air-conditioning systems you have on your property.

If you live in a rental apartment and are unable to install permanent units, a portable air-conditioner is the ideal option for you. These units also have wheels and a compact design, which makes it easy for you to move to unit from one room to another if necessary; and it can be reinstalled with minimal effort.

The Money Saving Aspect

As mentioned at the outset, these units can either supplement your existing HVAC system or used as an AC replacement. Most property owners are very conscious about the manner in which they use electricity in their homes or commercial establishments. In the warmer months, the air-conditioning unit is run for a longer period of time and you find your utility bills soaring during this time.

Fortunately, you can use a portable air-conditioning unit to cool individual rooms in your house and will notice a significant reduction in your energy bills. Here is a detailed look at how you benefit

Portable Air-Conditioning Units are Money Savers

1. Cools One Single Room at a Time

Regardless of whether you live in a large home or studio apartment, installing a portable air conditioner can help reduce cooling costs, as it targets one room at a time, rather than maintaining the temperature of your entire house at a standard level. In smaller apartments, these units can be used in place of central HVAC units as well.

In larger structures, the unit can be moved from one room to another as required. For instance, if you want air-conditioning in your bedroom, on particularly warm summer days, you can use this unit in that area at night; in the day time, the unit can be moved into your home office or any other space as required. When you cool only one room at a time, you end up using far less energy which helps reduce your energy bills.

2. Supplement Your Existing Unit

There are 2 primary reasons why you may want to consider operating a portable air conditioner in addition to your existing central HVAC system. It helps you keep your costs at manageable levels right round the year and you can cool one room in a more effective manner when the weather is too hot.

If you run the central unit on your property all year round, you aren’t going to be too happy with the way your utility bills look at the end of every month.  However, when you have a portable unit, you can operate the central system at a higher temperature and then use the former to maintain a cooler temperature in a specific area or room.

You may sometimes find that you want your bedroom to be cooler than the rest of the house, but don’t want to lower the temperature of the central unit just to accommodate that single room. You should consider placing a portable air conditioner in the bedroom, so you won’t have to pay to cool the entire house to that lower temperature.

3. Interesting Features

Most modern and advanced portable units come with various interesting features that help reduce costs. For instance, many of these systems have programmable timers that allow you to operate the units in the manner you want, right through the day. You can set the timers to run the unit at lower temperatures when you’re at home, and then raise the temperature when you are out. You can program these units to power on just an hour before you get back home and will have a very cool and comfortable space to return too, instead of a claustrophobic and stifling one.

4. Dual Functionality

While most people need these units only for cooling their homes, portable air-conditioning units are able to do much more. You can also find models that serve as heaters in the colder months, have a dehumidifier function for rainy weather and a fan function for days on which you only want some ventilation in the room. If you live in a region that experiences temperature swings across the seasons, you may want to consider investing in a portable air conditioner to accommodate these climatic changes.

5. Use It To Replace Your HVAC Unit

A portable air conditioner runs far more efficiently than a standard central unit; which means you don’t have to burn a hole in your pocket to maintain a comfortable indoor temperature in your home. A central HVAC system can significantly up your utility bills. So even if you have this installation in your home, investing in a portable unit can prove to be major cost saving. In some apartments, a central AC isn’t an option and a portable or window unit is the only solution. A portable unit is far more convenient and cheaper than a window unit and doesn’t require any special installations, so you save on those costs as well.

In Closing

Regardless of which way you look at it, opting for a portable air-conditioner can save you a significant amount of money, trouble of installation and maintenance. You can use it to complement an existing system or to replace it altogether. Look for wholesale air conditioner units that have features such as a programmable thermostat as that too saves you a considerable amount of money. If you feel you may need the room dehumidifying/heating functions, choose models that offer those.

Note- Before purchasing a portable air-conditioning unit, check whether your window’s structure would be able to accommodate it. These Units fit varying window sizes and the ones designed specifically for single/double-hung as well as sliding windows won’t be compatible with casement windows that open by swinging outward.
