The average cost to replace a condensing fan motor is $400 dollars depending on the HVAC company it may be more or less. The motor by itself usually runs between $50 and $150 dollars.
The reason for the high cost is having a HVAC service technician come out and replace the motor which is usually $50 dollars an hour plus the motors price which is often marked up since they bought it and took it out to your house.
For the Do-It-Yourself type person replacing a condensing fan motor is not a hard job. Some electrical and mechanical skills will be needed but buying a motor and changing it yourself is really not that hard.
Finding a place to buy the motor may be the hardest part since places like Home Depot and other hardware stores don’t carry condensing fan motors. The best place for a home owner to buy a condensing fan motor is online at Amazon or eBay. I like to use Amazon personally but it is a personal choice.
The way you can tell which motor you will need is by looking at the motor itself for a model number.
Sometimes model numbers will not be able to be found and a compatible replacement fan motor will have to be used.
HVAC technicians often carry universal motors that depending on how they are wired can run at different voltages and speeds.

A new Start Run Capacitor should also be ordered since a bad or one going bad can prematurely wear out your motor. They are usually not more than $30 dollars to replace. To buy a new start run capacitor read the micro farads (uf) and the voltage.
