Did you know that Americans spend more than $22 billion to cool their homes every year? When the summer months hit, air conditioning is necessary to cool down your home and make the blazing heat bearable.

You want to make sure your air conditioner is up and running and that you know the common noises it makes to catch any issues early. Keep reading, and we will walk you through your air conditioner making noise and when it becomes a problem.

Silence is Golden

The summer of 2019 was the hottest on record for the Northern Hemisphere. June through August was so hot, the heat shrunk the Arctic sea ice coverage.

With last summer being so hot, you want to prepare for the summer of 2020.

New air conditioning systems today are built to work efficiently and quietly. The efficiency helps lower your energy bills and will help with minimal need for AC repairs.

New systems are quieter; you should still be aware of when your AC makes noise so that you can catch an issue early.

Air Conditioner Making Noise

We are going to walk you through 5 everyday noises your AC makes and get right to the source.

You will most likely need to have a technician come check out the following noises because they can lead to more severe issues.

Five Common AC Noises and The Source:

You have probably heard a variation of these 5 common AC noises coming from your air conditioner.

However, you can reference back here if you ever forget the source behind the sound.

1. Loud Banging Noise

If you hear a loud banging noise, that sounds like something is slamming against the machine, it is most likely the compressor.

Your air conditioner may have normal wear and tear over time, and the compressor faces this too because parts inside can become loose and rattle around, which causes the banging.

2. Buzzing

You may hear buzzing from your outdoor AC unit or near the air handler. This is usually because of an electrical issue.

These issues can range from a failing motor, loose wiring, to a malfunctioning compressor. It would be best if you had a technician take a look because these could be critical issues.

3. Hissing

If you hear a hissing noise, similar to the sound of a snake, this is most likely the sign of the refrigerant leaking. The hissing is due to wear and tear on the copper lines that carry the refrigerant and you will need to fix or replace the wires.

4. Clicking

If you hear clicking, it could be because there is a small object in your blower, so it’s hitting the fan as it spins. If your AC won’t start and you hear the clicking, it’s usually a sign of an electrical issue with your thermostat, compressor, or capacity.

5. Squealing

If you hear a noise that sounds like metal grinding on metal or a squeal, coming from outside could be due to a bad compressor or issues with your outdoor fan motor. If you hear it coming from the inside, it could be a broken blower motor.

Test Run

Before June, you should give your AC a test run to ensure everything is working correctly.

Be aware of your air conditioner making noise and the potential issues it could cause. Now, you will be able to relay the problem to your technician.
