What Are the Signs That My AC Capacitor is Failing?

A failing AC capacitor can cause your AC unit to be inefficient and unresponsive. It can also be a contributing factor behind blown fuses or tripped circuit breakers.

Your HVAC technician will check for these symptoms when assessing your AC's condition, but if they notice other problems as well, a bad capacitor may be the culprit. Common signs of a failing capacitor include unusual odors from the outside unit, persistent humming noises, and insufficient cooling.

When you have a problem with your AC capacitor, it's important to catch it early to save money on repairs. Taking time to learn the basics of your AC's components and knowing how to spot problems early can help you avoid high repair costs and costly repairs down the road.
