5 Common Air Conditioner Sounds & What They Mean

Banging & Clanking Sounds

Banging and clanking sounds coming from an air conditioner typically mean there’s a mechanical issue within the system. These sounds most often occur when internal components break or have come loose. For example, some possible causes of banging sounds include compressor issues, a detached blower wheel, or a loose fan blade. So, what should you do if your AC’s making loud banging sounds? First, turn off your air conditioning to prevent further damage. Then, call our trusted AC repair technicians! Because these sounds are usually indicative of serious mechanical issues, it’s best to call a professional to check out your system right away. Our team can quickly diagnose the problem and get your air conditioner back up and running in no time!

Buzzing Or Humming Noises

While the soft hum of moving air is entirely normal during daily operation, a loud humming or persistent buzzing sound is most certainly not. Consistent buzzing noises are usually a sign of an electrical issue and should be addressed immediately. Some common causes of buzzing sounds include loose wiring or connections, a failing capacitor, a faulty motor, or debris in the outside unit. Since electrical problems pose serious safety risks, we highly recommend avoiding any DIY work and instead having one of our trained HVAC technicians inspect your system.

Clicking Sounds

Hearing a brief clicking sound whenever your air conditioning system turns on and off is to be expected. However, if your air conditioner is making a loud or persistent clicking sound, it could be a sign of faulty electrical components, a failing thermostat, loose parts, or problems with the compressor. As with buzzing noises, scheduling professional air conditioning repairs is recommended for clicking sounds since the problem could be electrical in nature. Don’t wait — if your AC is making clicking noises, prompt service is essential to preventing further damage.

High-Pitched Screeching Or Squealing

On top of being obnoxious and distracting, high-pitched screeching or squealing noises typically mean there’s an issue with your air conditioner’s moving parts. Whether due to worn-out motor bearings or belt issues, if left unchecked, these issues could eventually result in total system failure, leaving you and your family without air conditioning. Obviously, that’s the last thing anyone wants. If you hear screeching or squealing from your AC unit, the best course of action is to turn it off and call a professional HVAC technician immediately.

Rattling Or Vibrating

Rattling or vibrating sounds aren’t quite as concerning as those listed above, but that doesn’t mean they can be ignored. These noises are most commonly caused by issues like loose components or debris in the air conditioning system. While those issues may sound minor, they can still impact your system’s performance and energy efficiency over time. If you’re hearing rattling or vibration from your unit, it’s most likely time to schedule a professional AC tune-up!
