HVAC Fan Motor Replacement and Capacitor Replacement

Your heating and cooling systems are made up of many parts, which together work to keep your home as comfortable as possible. Two of these parts, the fan motor and capacitor, are responsible for circulating air throughout your system. Without them, there would be no hot or cool air in your home. Definitely not ideal.

Time for a Fan Motor and Capacitor Replacement

What causes issues with your HVAC fan and your capacitor? It could be anything from clogged air filters blocking airflow or an obstruction between the fan blades having damaged the motor to a swollen or overheated capacitor, or even a tripped circuit breaker. If one or more of these events arise, your HVAC system will probably suffer.

How do you know it’s time to replace your fan motor and capacitor? The signs of a failed HVAC fan motor and capacitor can be pretty obvious. If your HVAC system isn’t running properly, is making a rattling noise, or won’t turn on, you have a faulty HVAC fan motor or capacitor on your hands. If these parts have worn out or failed, you’ll need to have them replaced.

Signs it’s time for a new HVAC fan motor and capacitor

There are a couple of ways to tell it’s time for a fan motor and capacitor replacement. Here are a few signals to look out for:

  • Fan motor is running slowly

  • Motor overheats and runs intermittently

  • Circuit breaker to the unit trips often (you should only reset a breaker once — if a trip reoccurs, a service call is needed)

How Does an HVAC Compressor and Capacitor Replacement or Installation Work?

Get an assessment of your heating or cooling system

An HVAC specialist will assess your system — whether that’s your heating or cooling system⁠ — to find the source of the issue. If the fan motor or capacitor is at fault, your technician will discuss replacement as the next step. Often when it comes to failed fan motors and capacitors, replacing your entire system could actually save you money in the long run. Your technician will discuss that option if it makes sense for you.

Review the estimate with the specialist

Your quote will be based on the type of HVAC system you have, and the type and size of fan motor and capacitor it requires. You have options, like replacing the fan blade as well. Don’t be afraid to ask questions!

Install your HVAC fan motor and capacitor

An HVAC technician will come to your house to replace your system’s old parts with new ones. This typically takes between 1 to 2 hours, depending on the service provider.
