Your Furnace Replacement: All About the ECM

An ECM is a brushless blower motor with fully controllable speed and torque. The blower portion of the furnace is a major contributor to the electrical consumption of your heating system. Yet, blowers are not figured into the energy-efficiency ratings published by the furnace manufacturer. Therefore, a new higher-efficiency furnace mated with a conventional PSC…
