The Annual Fuel Utilization Efficiency, or AFUE, is used to determine how effectively furnaces use gas energy to heat an area. The higher the AFUE, the greater the furnace efficiency. Comfortmaker offers oil and gas furnaces ranging in AFUE ratings from 80% to 95%. Most of these models are Energy Star qualified and come with extensive warranty coverage.
