AC Blower Motor replacement:
The cost of your motor replacement will vary based on these 4 main factors($225 to $800) :
Motor type
Torque, speed and power usage
Motor brand
Other installation factors
These are the cost factors that will determine the overall price of a new A/C motor:
Motor type: Though there are many types of HVAC motors, most air conditioning systems’ default motor is a PSC (permanent split capacitor). However, they are not the most efficient or controllable motors on the market. ECMs (electronically commutated motors) are an increasingly popular motor upgrade, but they are more expensive. ECMs are more energy efficient than PSC motors (70% compared to 45%) and don’t require as much maintenance. So even though the initial cost of an ECM can be high, the overall energy savings typically balance out that price in the long run.
Torque, speed and power usage: Though motor construction may vary by type, all share the characteristics of torque, speed and power usage. As a general rule of thumb, more expensive motors will have higher torque (measured in foot-pounds), offer variable speeds and have more efficient power usage.
Motor brand: Some motor brands are more expensive than others. Common motor manufacturers include A.O. Smith, Manetek, Emerson, General Electric and Fasco. When you replace your motor, your technician will check your system or its user manual to determine if you have to use an OEM (original equipment manufacturer) motor or if you can use a generic replacement motor.
Other installation factors: If your blower is in a hard-to-reach spot, you might have a higher labor cost because it will take longer to replace the motor. Your technician could also find another issue in your system connected to the motors that needs to be repaired, which would also raise the cost.
