Why Is My Air Conditioner So Loud?


We rely heavily on our air conditioners from spring through autumn. No one wants to suffer through the heat because of a faulty air conditioning system, but that’s exactly what could happen to you if you don’t heed the warning signs of an air conditioner with a problem!

One of the most common questions we get at McGee Refrigeration is, “Why is my air conditioner so loud?” Often, this question is followed by, “Is that normal?” These are important and intelligent questions to ask, and it’s best to address them now and get quality AC repair in Visalia, CA right away if you have an issue with your unit. That way, you can be sure you and your family stay cool and comfortable as long as the hot weather lasts. Here are a few things you should know about a loud air conditioner.

Some noise is normal

No one has a completely silent air conditioner, so it’s not a problem if yours makes noise while it’s running. You might notice a variation in noise level depending on how old your unit is. Newer units have improved designs that help decrease overall noise while in operation. The bottom line is that some noise is just the usual order of business for a functioning unit.

However, if you notice new noises, or move into an apartment or home that has an existing unit that seems abnormally loud, you might want to have it inspected. At McGee Refrigeration, we are experts in AC repair and inspection, so give us a call if you have any doubts or concerns.

Noises can be benign—or indicate a problem

The noises listed below are common—to a certain extent. If they seem to be getting louder, or just have a bad quality to them, it never hurts to get the noise checked out. It’s best to get regular AC maintenance anyway, which will help ensure that potential problems are taken care of before they really get bad.

Common sounds, good and bad, include:

  • Grinding: This isn’t a good noise. It’s probably coming from a fan motor, and could indicate that a bearing is wearing out. Get the noise inspected right away.

  • Rattling: This noise could be nothing, or it could be a problem. AC units live outdoors, so it’s quite common to find sticks, leaves and other debris inside them, which can rattle around and create noise. However, it’s also possible that the noise is due to a screw or bolt that’s come loose. It could also be your compressor, if you have an older unit. Compressors, like any other component, wear down over time. Yours might just need to be replaced.

  • Hissing: This noise is also bad news. It frequently indicates that you have an issue with your ductwork, or that your unit is leaking refrigerant. This is not something that will go away, so take the time to call for AC repair as soon as possible. Get a certified HVAC technician out to your home as quickly as you can to prevent further damage or issues.

Remember, it’s important to keep your AC system in good repair if you want it to last a long time. Call McGee Refrigeration for regular inspections and AC repair in Visalia, CA.
