What Your A/C’s Noises Could Mean

All Contractor Marketing • March 13, 2018

Air Conditioner Noises

Just like every other year in Cobb County, summer is coming. This year it doesn’t look like it’s going to be a mild one. It’s important to make sure your air conditioning unit is up and running. Often, an air conditioner that’s been off for the last few months will make some unusual air conditioner noises when it starts up. Here’s what these noises might mean and what you should do about them.

Mechanical Failures

“Mechanical Failures” are noises best described as clanking, thunking, banging, or clicking during operation. A persistent rattle may also be a sound you hear. These noises generally mean that something is loose or has fallen out of place inside the machine. It can also mean a part is simply broken and needs to be replaced, but it’s generally not due to wear over time. It’s usually more a sign of something simply breaking or coming loose.

Persistent Operation Air Conditioner Noises

If the A/C unit starts up without issue but starts to take on a noise while it runs, this can be due to debris or trash getting into the unit. Leaves can occasionally make their way inside, especially after a few months without it running. Operation noises can be things like a humming or buzzing, or even something more high-pitched like a screeching noise.

What To Do?

Aside from very straightforward cleaning options when the issue is obvious, it is highly recommended to have an HVAC expert look at the issue. Attempting to fix it yourself could lead to anything from making the problem worse to the risk of electrocution. Getting an experienced pair of eyes to take a look is the safest way for both you and your A/C unit to prepare for the scorching Marietta summer.
