Why Is My AC So Noisy During Cooling Cycles?

Sometimes air conditioners operate louder than they should. This may be a specific problem that needs to be addressed, but sometimes certain air conditioning units are simply louder than others. The good news is, you can do something about it either way.

Reading to learn more about how air conditioning repair in Salem can help with a noisy air conditioner. We can also offer other solutions if your AC is operating perfectly normally albeit louder than you would like. 

Clicking Sounds

If your air conditioner is making persistent clicking sounds throughout the operation, this can signal that something is wrong with your AC starting up or turning off for a cooling cycle. Clicking is completely normal as long as it only happens a few times when your air conditioner first turns on or winds down from cooling your home. 

Persistent clicking should be treated as a red flag. Even if your home still feels comfortable, something is wrong inside of your air conditioner that needs to be addressed before it breaks down completely.

Humming Sounds

Humming is another problematic sound. If you hear your air conditioner humming, the capacitor may be going bad. The capacitor is a fairly small and inexpensive component located on the outdoor portion of your AC unit. It offers a little power boost during the start-up of a cooling cycle. This helps to eliminate some of the strain from the motor and ensures safe operation. 

Unexpected Noises

Outside of these two sounds, any other loud or unexpected noises should also be concerning. Your AC unit should never be particularly loud during operation. If it is, you need to schedule service and get down to the root of the problem.

Banging, rattling, or screeching can all mean that something major is going wrong inside of the system. Either a part is coming loose from its secured position or a fan blade is warped and scraping against a side wall.

Loud Airflow

It’s also possible that your air conditioner simply has louder than normal airflow during a cooling cycle. This usually points to a problem with the sizing of your AC unit. If it is too large for the square footage of your home, it may sound louder than it should. 

You do have some options for soundproofing your AC unit to help it seem quieter during cooling cycles. If you want to invest in additional insulation or a soundproofing blanket for your AC, just reach out to us for help. We can ensure you get the right soundproofing option that doesn’t block airflow into your system.

Then, when it is time to upgrade your current unit, be sure to ask about proper sizing so you don’t end up with another air conditioner that is too large for your home. A properly sized AC will also lower your energy costs and help to cool your home more effectively.
