With temperatures starting to go up quickly, it won’t be long before you kick on the AC to stay cool. You may have already turned on the air conditioner to make sure everything is working properly. If you heard some noises coming from your AC unit, you may be concerned, but fortunately not all noises mean that your AC unit is breaking down or falling apart. Let’s take a look at some of the most common noises that an AC unit can make and why they might be occurring.

Air Conditioner Making Clicking Sounds

With many units, you may hear clicking. If the clicking is occurring when your unit kicks on or turns off, then it’s completely normal. But, if the clicking is repetitive, then it might be an issue with a relay or thermostat. We recommend contacting an HVAC professional before a serious issue arises. Early fixes and prevention are key to avoid massive repair bills. 

Banging or Rattling Coming From Your Air Conditioner

Banging and rattling noises often mean that a part is broken or loose inside your HVAC unit; not a noise that should be ignored! Unfortunately, you probably won’t be able to ignore it because of how loud or annoying it is. We recommend that you contact an HVAC professional rapidly to address the problem. Hopefully, it’s something that can be easily replaced. If you ignore the problem, the loose or broken part could easily rattle around and break other parts as well.

If Your AC is Buzzing

If you hear your air conditioner buzzing, it can be difficult to diagnose because there can be many different causes. It could be a loose part, a dirty condenser coil, a loose motor, or a bad blower. With a buzzing sound, it’s best to contact an HVAC tech who can properly diagnose and address the problem. 

Squealing Noises Coming from Your AC

Squealing is a horrible noise to hear coming from your air conditioner. Squealing is often a sign that the belt that connects to the motor has slipped or the condenser fan motor bearings may be going bad. As with most other noises, it’s best to contact your air conditioner technician to have the problem rapidly resolved. 

If Your AC is Humming

Humming isn’t always serious, but it could indicate a potential problem. Loose parts or piping could cause enough vibration to lead to humming. It could also be related to the compressor, which you may notice if the compressor starts to hum but won’t actually start. Loose wiring or a bad compressor can cause this issue. Humming could also indicate a potential electrical issue, which should be remedied quickly. An HVAC tech will be able to quickly find the issue and get you up and running in no time.
