I Hear A Lot Of Talk About High-Efficiency Heating Systems. How Do You Determine A Heating System’s Efficiency?

Submitted by admin on

One indicator is Annual Fuel Utilization Efficiency (AFUE). All heating equipment manufactured after 1980 has been required to have a label indicating its AFUE. The AFUE ratio is a measurement of a heating system’s seasonal efficiency, taking into account how well the system performs over an entire season of starts and stops. Modern heating systems can range in efficiency from 81% to 95%. If your system’s AFUE is lower than this range, talk to us about your replacement options.
