Gas Furnaces
Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER/SEER2 and EER/EER2) can vary widely. For air conditioners, the Department of Energy’s (DOE) new minimum efficiency standards vary by region, so your choice of AC units will depend on where you live.
The DOE’s regional breakdown by state is as follows:
- North – 80% AFUE
- Southeast – 90% AFUE
- Southwest – 90% AFUE

Gas Furnace Product Offering

Let Schaef Air Heating & Air Conditioning 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 (909) 944-5111.
