The AC Noises It’s Best Not to Ignore

You don’t need to have lived in College Station, TX too long to know that heat and humidity can quickly arrive here and make air conditioning pretty much a necessity. When temperatures rise, the last thing you need is an air conditioner that’s on the fritz. This is a risk that can be reduced if you stay on top of potential AC problems by paying attention to signs of an issue. One of the telltale signs suggesting it’s best to call us for HVAC service is hearing certain sounds as your system runs that aren’t considered normal. Below, we explain some of the AC noises it’s best not to ignore.


Rattling is never a good sign with anything mechanical. This is also true for the cooling system you’re using. It could mean something is stuck in the condenser fan if it’s coming from your outdoor AC unit. Rattling can also be caused by loose screws or parts that are no longer properly secured. This applies to the outside unit as well as the inside air handler.

Bubbling or Gurgling

These are AC noises that could be a sign of a refrigerant leak or low refrigerant levels. This is an issue best addressed sooner rather than later. We say this because low levels of this essential liquid can contribute to poor system performance and the possibility of a spike in related utility costs. A money-saving way to catch refrigerant issues early is with routine AC maintenance that includes a check of refrigerant levels.

Squealing or Squeaking

Loose fan belts or worn bearings in your AC unit can result in noises of this nature. If you’re just hearing occasional squeaking or high-pitched squealing when your system is running, it’s usually an easy fix an HVAC technician can take care of fairly quickly. But if you hear a loud screeching noise or really loud squeaks, it could be an issue with the condensing unit or an indication that the compressor may be failing.

Persistent and Recurring Clicking

It’s not unusual to hear clicking briefly when your cooling system is turned on or off. What warrants professional attention is hearing a series of clicks that’s more consistent and lasts longer. This is often a sign of a bad switch or problems with other electrical or mechanical components. Due to the potential safety risks involved, these are issues that should only be addressed by an experienced HVAC technician.
