80% AFUE Rating
Upgrading your old model furnace with a new higher AFUE-rated furnace could save you significantly on your energy bills.
Variable Speed Blower While operating in continuous fan, variable speed can save up to 2/3 on electric usage. When properly matched to a condensing unit, variable
speed can increase the SEER rating of your cooling system, which saves you energy and money
Variable Speed Blower In continuous fan operation, variable speed provides more even temperatures in the home. During summer, the variable speed motor moves air slowly over the indoor coil to reduce humidity.
Two-Stage Operation Runs at low capacity during mild weather, saving you fuel and money. Automatically switches over to full capacity to keep you warm on colder days
