Gas Furnaces
Today's new high efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that can be sold in the United States today is 80% for the Southeast and Southwest, with 90% being the minimum in the North.
Our current product offering starts at 80% AFUE and goes all the way to a very efficient 98%+ AFUE rating. Depending on your average usage, higher AFUE rated furnaces can significantly reduce your gas bill.
The DOE’s regional breakdown by state is as follows:
- North – 90% AFUE
- Southeast – 80% AFUE
- Southwest - 80% AFUE

Let Bill Mohn Heating And Cooling Help Pick The Right Furnace For Your Home
We offer many furnaces with variable and multi-speed features that can provide enhanced indoor comfort by slowly ramping up to your thermostat setting rather than simply turning on at full speed. This alleviates the "cold air blow" often associated with single speed furnaces, and dramatically reduces system noise. Call us now at (484) 796-1685.
