Loud Noises Your AC is Making and What They Mean

Sometimes, you might happen to hear strange noises coming from your central air unit. While these could seem ordinary to some homeowners, it’s essential to have them checked out by a professional. Before you panic, here’s what some of the most common noises could mean.

Bumblebee Buzzing

Luckily, there’s a slim chance of having an actual bumblebee in your unit — but if you happen to hear any sort of buzzing, that could signal that your system has some loose parts that are moving around. Think of it like this: if you put a nut or bolt on top of your washing machine while it’s running, you’d hear the parts buzzing around the top. The same concept applies to your AC when it has parts that are on the loose.

Ear Piercing Noise

One of the most alarming sounds that any AC could make is one that resembles a high pitched screaming noise. Granted, it could be a horror movie playing in the other room but that’s usually a slim chance. If you happen to hear this noise, there’s a chance that your AC could have a refrigerant leak. This is extremely dangerous and can take a toll on your unit, as well as the well-being of your home.

Constant Clunking Around

Another possible suspect that your air conditioner needs repair is if you hear a loud, aggressive clunking noise — almost as if someone took a hammer and started hitting the compressor outside. While this could signify that you have a broken or loose part (just like the buzzing), it could also mean that there is something wrong with the fan inside of your unit. The blades on this part could be loose or hitting up against another piece of the AC, which could spell disaster.

Are Strange Noises Coming From Your AC Unit?

While these are only a few of the many strange noises you can hear from your AC, it’s essential to have regularly scheduled air conditioner maintenance to help eliminate any potential problems that you may run into.
