ECM TECHNOLOGY
ECM (Electronically Commutated Motor). This new technology is a brushless DC motor with all of its speed and torque controls built right in. This allows the motor to adjust its speed to ensure optimal airflow at all times. In addition, ECMs are considerably quieter and less expensive to operate than conventional furnace fans.
ECMs use significantly less electricity to deliver the warm air from the furnace and the cool air from the central air conditioner throughout the home. With their adjustable speed design, furnaces with an ECM operate with as little as 80 watts of electricity. That's as much as 75% less energy than standard fan motors which run on high most of the time.
Forced Air Furnaces (gas, electric, propane, oil) equipped with an Electronically Commutated Motor (ECM) inside have lower annual operating costs (25–75% less) depending on how you use the furnace fan. Some homeowners choose to run their fan continuously to help even out warm and cold spots in their home or to provide extra air filtration which may be valued due to health concerns.

What are the benefits of an ECM in a Forced Air Furnace or Heat Pump Air Handler?
- Lower annual operating costs (25–75% per year) based on usage
- Energy savings every time your HVAC system is operating (every unit of energy (kWh) saved is one less you have to pay for)
- As little as 80 watts of power required for operation—that's less than a standard electric light bulb
- Reduced temperature fluctuation
- Quieter running system
- Easier to maintain an even temperature throughout the home
- Increased comfort
- Lower drying effect of indoor air during the winter heating season
- Reduced stale air and improved air quality
