It’s another hot Texas summer, and your air conditioner is under a lot of pressure to keep your home cool when the air outside heats up to the triple digits. It has to work hard to draw the warm air out of your house, cool it, then send it back in to make your environment more comfortable. This extra workload can cause an AC unit to overwork itself and start to break down. When that happens, you might notice some signs of an impending failure, like funny noises coming from your unit.

AC Noises: What They Could Mean
If your AC unit was quiet before, but now it’s obnoxiously loud, we recommend getting it looked at right away by a professional. It could need repairs. Putting them off will only make the problem worse, and might require you to purchase a new unit in the long run. The sooner you can figure out what’s causing the noise and get it fixed, the better.
Here are some common AC noises and what they could mean.
Banging and Clinking
These noises usually indicate a loose or broken part. They could also mean there’s a part of the system that is out of balance. Fan blades could be unbalanced and striking other parts, or your compressor could need to be replaced.
Buzzing Sounds
Buzzing could indicate a number of problems. Loose parts could be vibrating at a high speed. Dirt and debris in the unit could be rattling around. Buzzing could also be a sign that your fan blades are about to fail, or that your blower is going bad. Hopefully it’s something that can be fixed by cleaning the compressor.
Frequent Clicks
AC systems click when they’re starting or ending a cycle. If your is clicking on and off too often, there could be a problem with your control or thermostat. This could be an easy fix if caught early enough, but ignoring the problem could lead to electrical issues in your home.
Squealing
Blower and fan squeals may be transmitted through your ventilation system. Indoor and outdoor motors tend to squeal loudly when they’re going bad. The blower wheel and housing will also squeal when they malfunction. If this sound is something you’ve never noticed before, get it checked out right away.
Humming
A humming sound could signal that something inside your air conditioner is loose or unbalanced. Loose parts and refrigerant piping can cause vibration. If this vibration goes unaddressed, it can cause more serious maintenance issues down the road. Loose wiring, a dying motor, or a stalling compressor can all make buzzing or humming sounds.
When You Should Call for Help
Loud whistling or screaming noises could be caused by a refrigerant leak or high pressure within your compressor. This is a potentially dangerous situation. If you hear these sounds, turn off your AC and call a professional immediately. Refrigerant leaks can cause harmful fumes to escape and pose a hazard to you, your family, and your pets.
