Why Is My Air Conditioner Making a Banging or Clanking Sound?

Posted on

It’s a fact: air conditioners are rarely totally silent, even if you have a newer model that operates relatively quietly. While your New Jersey home’s air conditioning unit will never be completely quiet, there are a few noises that it definitely shouldn’t be making. If you hear your air conditioner making a banging or clanking noise that is disruptive, there could be a few different problems at play—none of which are good news for your AC.

If you’ve been hearing this noise for a while and you are ready to schedule air conditioner repair in your Hunterdon County, Somerset County, Mercer County, Middlesex County, or Warren County home, call Air Professionals at ​908-284-2422 today!

The Most Likely Reason Your AC Is Making Banging or Clanking Noises (& How to Fix It)

We often get calls from our New Jersey neighbors about hearing a banging, clanking, or knocking noise from the air conditioning unit. A lot of the time, our neighbors tell us that they experience the issue when the outdoor unit is running, but that they stop hearing the noise if they switch their thermostat to “Fan” mode.

What this indicates to our team at Air Professionals is that there is likely something caught in the fan of your cooling system’s outdoor unit—or, at least, that the fan is hitting something. This could be debris from your yard that has become lodged in the fan (such as sticks or leaves), or it’s possible that the fan itself has become loose and, while it’s running, it’s hitting the exterior of its cage when it shouldn’t be.

If this accurately describes the issue that you are experiencing in your home, you should not continue to run your air conditioner! Doing so could worsen the issue and make for a much more costly and time-consuming repair.

Another reason your air conditioner could be making a clanking, banging, or knocking noise could be some part of your unit’s blower assembly or motor has come loose, and it’s now hitting against other parts of your system. Again, if this is the case, you should not continue to run your air conditioner!

It’s important to call us to repair this issue before the part disconnects altogether, at which point you’d hear even louder banging noises, because the part would just be rattling around somewhere in your system. This is dangerous and should be resolved as quickly as possible.

The best course of action is to schedule an air conditioner repair appointment with the Air Professionals team. We’ll diagnose the issue and repair it as quickly, efficiently, and affordably as possible so you can continue to keep your family cool in peace and quiet.
