Efficiency gains on both gas and electrical consumption can be achieved when installing multi-stage furnaces that meet new federal furnace-fan efficiency standards. A multi-stage furnace operates much the same way as a single stage furnace, except that the amount of heat it provides is not always at the higher design rate for the coldest day of the year. Fan efficiency is gained by replacing traditional PSC motors with one of two types of ECM motors: constant airflow or constant torque. Learn how these technologies are typically packaged together by manufacturers and how they can reduce energy costs and increase comfort for occupants.
