A malfunctioning component can significantly affect your air conditioner’s performance. One of the most crucial HVAC components is the capacitor, a cylindrical or cube-shaped battery that charges and starts the motor. How can you tell if your AC has a bad capacitor? By keeping an eye out for the following warning signs:
The AC Takes a While to Start
When an air conditioner has problems getting started, it’s called hard starting. This is when the AC’s compressor has trouble starting or randomly shuts down after it’s turned on. A bad capacitor is one possible culprit, but it isn’t the only one. For instance, issues with the compressor itself could be preventing the AC from starting. Only an air conditioning contractor can pinpoint the exact cause, however. If you experience this particular problem, it’s best to leave the troubleshooting and diagnosis to the professionals.
Higher Energy Bills
An AC unit that randomly turns on and off consumes more electricity. Remember: AC units use more energy during the start-up cycle. As such, it’d be a good idea to monitor your household’s electricity consumption and energy bills.
Clicking and Humming Noises
Clicking noises are a sign the AC’s capacitor is starting to fail. Keep in mind that even with a bad or failing capacitor, an AC unit might still be able to start. However, it won’t be able to run for long, and the motor might start to produce humming sounds. Left unattended, the motor might even burn out. That’s why if you hear or smell anything unusual coming from your AC unit, you need to turn it off and call an experienced air conditioning repair service company as soon as possible.
