Is it OK to buy HVAC equipment online? Many DYI-savvy homeowners are tempted to do so but wonder if it’s the right choice for their homes. It’s NOT a bad idea to purchase HVAC equipment online (often at a lower price) if you do research ahead of time. The most important aspect of buying a gas furnace, air conditioner, or heat pump online, is to consider the safety of you and your family and if the equipment will retain a warranty from the manufacturer. We recommend consulting with a qualified HVAC professional before any major HVAC project in your home. Seek their advice and DO NOT attempt to do this project on your own. An HVAC professional will have the know-how and tools to properly install your unit and calibrate it to the needs of your home. Be sure to have it cleaned and serviced annually to keep it running like new.
