The ECM Motor In the simplest terms, an ECM motor lowers the total electrical consumption of an AC or furnace and helps to maintain proper air flow through the system. ECM motors contain a microprocessor, which is the key component of what makes them able to provide higher efficiency.

An ECM has an expected lifespan of roughly 10 years, while a PSC motor only has an expected lifespan of eight years.

How Furnace ECMs will affect you. Climate Control Company and other HVAC maintenance contractors were able to the old-style motors if the furnaces were already in stock but going forward all furnaces installed will have the ECM fan motors.

Some older ECM motors will overheat and even fail when constantly running in over-amped conditions. Newer models are designed to drop airflow but time will tell on how well they will hold up. Other consequences of high static installations include noise at the registers from higher air velocities.

What Is The Difference Between Variable Speed And ECM Motors? The largest difference between variable speed motors and ECM motors is that a variable speed motor is much more efficient. While ECM motors are efficient enough to be legally acceptable, they still have certain limitations.

The term "Variable Speed" actually refers to the blower motor inside the furnace or air handler. It's an Electronically commutated motor, or (ECM). ECM's are DC motors that function using a built-in inverter and a magnet rotor, and as a result are able to achieve greater efficiency than most AC motors.
