80% AFUE – Downflow Air Direction
Our 80% AFUE downflow gas furnaces are metal-vented, non-condensing units designed for homes with ductwork beneath the floor with supply air going downwards. They offer reliable heating performance, easy installation, and long-term durability using standard B-vent or single-wall venting.
The AFUE (Annual Fuel Utilization Efficiency) rating indicates how effectively the furnace converts fuel into heat. An 80% AFUE model transforms 80% of its fuel into warmth, with 20% lost through exhaust—providing a balance of efficiency and affordability.
Built for quiet, consistent performance, these furnaces are ideal for both residential and light commercial applications.
