Why Is My Air Conditioner Making Loud Noises?

Have you noticed your air conditioner making loud noises, possibly waking you up throughout the night, or making strange noises in general? If you have, there are a few things to consider; older air conditioning systems will be louder because they do not have the sound dampening technology that some of the newer systems have. So if its generally louder but isn’t making strange noise then you may want to talk to your certified HVAC contractor about options to help control the volume of your air conditioner. If, however, you hear rattling, popping, hissing, grinding, or any high pitched screech coming from your air conditioner then take the following steps.

Turn off power to your Air conditioner.

Letting the air conditioner run with any of these noises means that you could cause major mechanical issues. The noise itself means that there could be a breakdown or broken part already, cutting power will reduce the likelihood that other parts of your system will be affected.

Call a Certified HVAC Contractor.

Once you have turned off all power to your air conditioner, call your local certified air conditioning contractor to have a technician come and diagnose the issue causing the loud noise. In most cases the technician will not be able to repair your system in one visit if there is a mechanical issue. Once the source of the problem is found the technician will have to order replacement parts and then return to install them. However, if the loud noises coming from your air conditioner are not mechanical, the technician should be able to clean out any debris or obstructions that may be causing the problem.

Check Your Air Filter.

An easy step that you can do right away is check your air filter. A clogged air filter can cause your air conditioning system to go into overdrive and work very hard to get air into your home. This can cause your air conditioning system to operate loudly and even cause major breakdowns. Checking your air filter regularly helps prevent this issue.
