Why Is My Air Conditioner Making a Weird Noise?

If you’ve recently noticed an odd noise coming from your air conditioner, don’t ignore it! The longer you put off calling Apollo Beach AC Repair to look at the problem, the more you risk the chance of something even worse happening to your unit down the road.

While some noise issues are minor and fixable, others can indicate severe problems with your system that could result in thousands of dollars in repair bills and lost business income if left unattended for too long. Many factors contribute to the noises your air conditioner makes, and there are even more ways to fix them so that your unit can return to its regular operation.

Dirty Blower Wheel

What is that high-pitched screeching sound coming from your air conditioner? This may be what you’re hearing, and it’s usually an indication that there is dirt in your blower wheel. The blower wheel takes air from outside your home and blows it through cold coils to cool it down. If there is dirt in your blower wheel, some of that dirt can wear away at your blades, causing them to vibrate against one another as they spin.

Blocked Air Filter

Noisy air filters may sound like a minor annoyance, but they indicate something more serious. A clogged filter keeps your system from operating as efficiently as it should. Instead of pulling hot air in and pushing cool air out, your system is trying to force cool air through an impassable layer of dirt and debris. After a while, you’ll notice your unit starting to run longer than usual or even shutting off without any explanation—both are signs that your filter needs to be replaced.

A Leaky Evaporator Coil

Leaky evaporator coils, also known as refrigerant leaks, can be either damage caused by condensation in your unit or a problem with your thermostat. When condensation occurs on your coil, you may hear its noises during regular use. This is typically normal. However, if you aren’t hearing any unusual sounds and are noticing strange odors coming from your air conditioner unit, it could signify an evaporator coil leak.

The Compressor has Been Seized

Your compressor may have seized if your air conditioner suddenly starts making strange noises or behaving erratically. This happens when dirt and dust get into its bearings and clog them up. Usually, you can fix it yourself by removing and cleaning out its bearings; if not, you’ll need to replace it with a new one. It’s important to have an HVAC technician inspect your unit before trying these repairs yourself.

Calling in a Professional HVAC Technician

If you’re hearing strange noises coming from your air conditioner, first off, don’t panic. Not every noise is a cause for alarm, and plenty of things can be done to solve these issues without having to call in an HVAC professional.
