Gas Furnace
A gas furnace is one of the most efficient ways to heat your home.
Furnace Efficiency
How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher that percentage, the more heat the furnace can wring from each therm of gas—and the lower the environmental impact of its emissions.
