The Condenser Fan Motor You Need Is on the Shelf

A condenser fan motor failure on a 95-degree day can't wait on a distributor's lead time. Our St. Louis warehouse keeps the most-specified HVAC motor replacement models in stock: PSC, shaded-pole, and high-efficiency ECM types.

Bring the old motor, the nameplate, or just a photo. Our counter staff matches air conditioner fan motors by frame size, RPM, voltage, and rotation, and can configure the wiring before you leave.

Questions

Frequently Asked Questions

How do I know which condenser fan motor I need?

Match horsepower, voltage, RPM, frame size, shaft size, and rotation direction from the nameplate. If the nameplate is unreadable, bring the motor in or send photos to our counter staff. We match motors daily that other shops give up on. Call (314) 531-1888.

Do you stock high-efficiency ECM motors?

Yes. We carry standard PSC motors, shaded-pole motors, and electronically commutated (ECM) motors for high-efficiency systems, plus the modules and accessories that go with them.

Can you replace just the motor instead of the whole condenser unit?

In most cases, yes. If the compressor and coil are healthy, replacing a failed condenser fan motor costs a fraction of a new unit. We'll help you confirm the right replacement spec before you buy.

Do you sell to homeowners or only HVAC contractors?

Both. No account needed. DIY-ers get the same commercial-grade motors and the same counter help contractors get.
