Did you know there's
a motor in there?
The motor matters.

Yes, your home’s heating and cooling system has motors! They run the moving parts of your system, like the fans and blowers that circulate air throughout your house. Some motors are more energy efficient than others.

Two types of motors

 

PSC Motor

Many systems use a blower motor called a PSC (Permanent Split Capacitor) motor. The PSC motor is a basic motor included in some heating and cooling systems. It typically has only one setting: ON. It turns on when the thermostat tells it to, and turns off when the house’s internal temperature reaches the mark set on the thermostat.

 

Single-stage system disadvantages

  • Noise
  • Draftiness

ECM Motor

The ECM (Electronically Commutated Motor) is significantly more energy efficient than the PSC motor. The ECM is smart and efficient, designed to operate continually at low speed and then turn to high speed when the thermostat indicates. Running continuously keeps the air circulating in your house, which helps prevent temperature swings and draftiness in your home and makes your air filter and humidifier work better.

ECM benefits:

  • Quietly ramps up to its high setting
  • Uses 30-50% less electricity than PSC motors
  • Results in lower energy bills
