Why is My A/C Rattling? 4 Top Reasons Explained

Midland and Odessa are experiencing one of the hottest summers in years! That’s why it’s critical that your air conditioning stays running properly to keep you cool. In this post, we’ll talk about some of the signs that something could be going wrong, including a loud rattling sound that can sometimes be heard while the system is running.


First, it’s important to know that any sort of unusual noise coming from your HVAC is never a good sign. One possible culprit of a rattling sound is that debris has found its way into your system. That could include sticks, rocks, or leaves that may have fallen into your exterior unit. Keeping the area around the unit clear of debris will help prevent this.


Another common cause of a rattling sound could be loose panels. These panels enclose your outdoor unit and are screwed into place, but can loosen over time. A standard screwdriver can fix the problem, but if the noise continues, be sure to keep searching for the source or have an expert come out to evaluate.


The fans and blowers inside your unit are what move the air to and from your home. They will eventually wear down or malfunction, and if they do, you may hear a loud rattling noise. This is not something that should be fixed on your own. It’s important to contact a licensed HVAC technician, like ours at The Bosworth Company, right away to take a look.


You can see the giant blade in your exterior unit, but there are fan blades in your interior unit as well. These can work themselves out of place, and potentially hit the inside of their compartment continuously while running. If that’s the case, you’ll definitely hear what sounds like a rattling, or even a clanging. This type of issue should absolutely be repaired by a professional, as it may require a full fan replacement.
