The 7 Most Common Bad AC Capacitor Symptoms

Homeowners can resolve some air conditioning problems with a quick DIY fix or repair. However, when it comes to a failed AC capacitor, your home’s HVAC system will need professional attention. How can you tell if your air conditioner’s capacitor is bad or experiencing failure? Here are some common symptoms of a bad AC capacitor.

1. AC Not Blowing Cold Air

An air conditioner that doesn’t blow cold air is one of the first signs of a problem many homeowners notice. Try turning your system off and back on again, and if the problem persists, you’ll need to call in for professional help.

Are your energy bills creeping upwards? An AC capacitor failure may be to blame. The harder your air conditioning system has to work to perform the job, the more energy the system will use.

3. Humming Noise

Listen to your AC system when you turn it on. If you hear a humming noise from your AC, or if it is hesitant to start, your capacitor may be failing.

4. Old HVAC System

An aging HVAC system will eventually stop working for one reason or another. If your AC units is several years old and goes through spurts of refusing to turn on, you may need to replace the capacitor.

5. AC Turns Off On Its Own

If your AC shuts off on its own every now and then, it may indicate something is wrong with your capacitor.

6. AC Doesn’t Turn On Immediately

Does your AC sometimes take a while to start once you turn it on? This is also a sign of a bad or failing AC capacitor.

7. AC Won’t Turn On

If your AC unit doesn’t start at all, a bad AC capacitor could be the culprit.
