The Goodman GMS80603AN is a 1.5-3 ton single-stage, multi-speed gas furnace with a patented aluminized steel tubular heat exchanger and high-efficiency hot surface ignition system. This means you get comfort and cost savings from this energy saving furnace. You set the multi-speed motor to operate at the level most comfortable for you and your home. This furnace has a rating of up to 80% AFUE (Annual Fuel Utilization Efficiency), meaning that 80 cents of every dollar of heating energy expense heats your home, compared to some older central heating systems which can be rated at only 60% AFUE.
These furnaces are run-tested for heating or combination heating/cooling applications. With a heavy-gauge, reinforced, wrap-around insulated steel cabinet and durable baked enamel finish, these gas heaters can be installed in a utility room, closet, alcove, basement or attic. (Not intended for use in mobile homes.)
Operates as a natural gas furnace out of the box, and can be easily converted to a propane furnace with optional propane conversion kit (see Accessories tab).
