The ECM Motor: How It Boosts Your HVAC System's Energy Efficiency
Today, many HVAC systems are no longer manufactured with the older Permanent Split Capacitor (PSC) motors, and instead use the new Electronically Commutated Motors, or ECMs. Motors are used in furnace fans, condensers, and air handlers, and HVAC systems with ECMs use less electricity and, therefore, get better energy savings.
