6 Signs Your Capacitor Needs to Be Replaced

When To Call an HVAC Technician

Picture of a man diagnosing an AC unit.

Nowadays, a cooling device is generally a part of most American homes, and without it, hot days can become unbearable. Air conditioning units are the only efficient air-cooling tools most homeowners can get. Air conditioning (A/C) units need to be well-maintained and kept in tip-top shape as they're used pretty frequently in homes. As with most devices, there comes a time when your air conditioner's capacitor ends up faulty or even damaged. Most homeowners fail to recognize when their air conditioning device has a bad capacitor.



Damaged Air Conditioner Capacitor Effects:


Humming Sounds

When trying to identify the condition of your air conditioner's capacitor, consider listening to the device when you switch it on. If you hear your A/C emitting a humming noise, your capacitor may be falling short.


The Air Conditioner Isn't Blowing Cold Air

The A/C failing to blow cold air right into your residence is just one of the very first indicators that there's something wrong with its capacitor. With that in mind, attempt turning your system on and off once again to see if anything changes. If the problem lingers, get in touch with a specialist so they can check out the AC and figure out if the capacitor is the issue.


The Air Conditioner Turns Off On Its Own

According to specialists, most air conditioning devices nowadays will suddenly turn off on their own if they detect any problems with their parts. For that reason, if you see that your air conditioner shuts down on its own from time to time, this can be an indicator that there's an issue with its capacitor. To properly evaluate your air conditioning unit, it's best to work with an AC repair technician.


Your Energy Costs are Climbing

If you notice that your energy expenses are rising despite taking the necessary actions to save energy, the failure of your air conditioner's capacitor might be the problem. The explanation for the increase in expenses is that when your A/C has a faulty capacitor, it works less efficiently than usual to perform its task, leading to the unit utilizing more energy than needed.


The Air Conditioner Does Not Turn On Quickly or Won't Turn On At All

If your air conditioner is slow to begin or takes a long time to switch on, it's likely that its capacitor has already stopped working or is getting ready to. If this occurs, you'll need to change the capacitor to get it to work again, which can cost you a significant amount.                                                                                                                                                                                                                                                                                                          Having read the above, do you require a specialist to repair your home's cooling system?
