When you're in the market for a new HVAC system, look for one that has an electronically commutated motor (ECM) outfitted for variable speeds as part of the furnace or air conditioner. These motors offer significant advantages over permanent split capacitor (PSC) motors because they use less electricity, run more quietly and adapt their speeds to conditions in your home. Also known as a variable-speed blower motor, an ECM with a motor controller can operate at whatever speed is needed to meet the conditioning needs of your home and the specific airflow and filtering factors in your HVAC system. For example, if your air filter is dirty, a variable-speed ECM will ramp up its speed to compensate for the restricted airflow.
