HVAC Motors

HVAC motors serve as the electrical powerhouse behind blowers, fans, compressors, and other rotating equipment across furnace, air conditioning, refrigeration, and commercial HVAC systems. Motor type, torque, and capacity vary widely depending on the application.

Furnace Part Source carries a broad selection of HVAC motors for residential, commercial, and industrial equipment, covering multiple motor technologies and horsepower ranges.

Common HVAC Motor Types We Carry

Common motor types include:

  • Induction motors for durable, efficient operation in blower and fan applications.
  • Split-phase motors for equipment requiring quick starts at low speed.
  • Permanent split capacitor (PSC) motors for energy-efficient refrigeration and condenser applications.
  • Shaded pole motors for small fans and blowers.
  • Variable-speed ECM motors for higher-efficiency, modulating applications.

How to Find the Right Motor

Before ordering, check the motor nameplate and confirm the horsepower, voltage, RPM, frame size, and rotation direction. Many motors have been updated with newer replacement numbers, so the original motor may not always match the current replacement exactly.

For best fit, compare:

  • Original motor part number
  • Horsepower and voltage
  • RPM and frame size
  • Rotation direction and mounting style
  • Phase, such as single-phase or three-phase

Motors From Leading HVAC Brands

Our catalog includes motors from Carrier, Regal Rexnord (Century Motors and Marathon), MARS, Modine, York, Rheem-Ruud, Nordyne, Aaon, Greenheck, PEMS, and other major manufacturers, covering a wide range of HVAC and refrigeration applications.

Need Help Matching a Motor?

Not sure which motor you need? Use the motor nameplate information, along with your equipment model and serial number, to narrow the search, or contact Furnace Part Source for help identifying the correct replacement.

HVAC Motor FAQs

What is the difference between an induction motor and a PSC motor?

An induction motor uses a rotating magnetic field to drive the rotor and is valued for durability, while a PSC motor uses two capacitors for starting and running and is known for energy efficiency, often used in refrigeration and condenser applications.

What information do I need before ordering an HVAC motor?

Gather the horsepower, voltage, RPM, frame size, phase, and rotation direction from the motor nameplate, along with your equipment's model and serial number.

Can I replace a single-phase motor with a three-phase motor?

No. Single-phase and three-phase motors are wired and powered differently and are not interchangeable without significant electrical modification. Always match the original phase configuration.

What are shaded pole motors used for?

Shaded pole motors are typically used in small fans and blowers where simple, low-torque operation is sufficient, such as certain unit heaters and small circulation fans.
