Should You Call An AC Repair Company For Intermittent Squealing Sounds? | Chandler, AZ

You’re sitting in your living room, trying to enjoy a nice, cool breeze from your air conditioner, when suddenly, you hear a loud squealing noise. Then, just as quickly as it started, the noise stopped. A few minutes later, it happens again. Although this problem might seem minor, it could indicate a serious issue. So, what’s causing this intermittent squealing sound from your AC unit? And more importantly, should you call an AC repair company to come to take a look at it? Read on for answers.

Possible Causes of Intermittent Squealing Sound from the AC

1. Age

One possible cause of intermittent squealing sounds coming from your air conditioner is age. As units get older, they start to experience more wear and tear. This can cause different parts to become loose, which results in squealing sounds when the unit is turned on. If your AC unit is starting to make more squealing than usual, it might be time for a replacement. You should call an air repair company to look at your unit and give you their professional opinion. They will recommend a new unit if age is the cause of the sound. You should get a new AC before the old one completely breaks down and leaves you without any air conditioning.

2. Loose Parts

Another common reason for intermittent squealing sounds from your AC unit is loose parts. As units get older or are not properly maintained, different parts can start to lose. The blower wheel or belt-driven pulleys are the most common areas where you might hear squealing noises. If you hear squealing noises coming from these areas, call an AC repair company in Chandler, AZ, for an inspection, tightening, or replacement of the parts.

3. Debris in the Unit

If there is debris in your AC unit, this can also cause intermittent squealing noises. Debris can build up over time and cause different parts of the unit to rub together, creating squealing sounds. To fix this problem, you need to clean out the debris so that everything can move freely again. Debris is especially likely to cause the squealing noise if there have been recent storms or high winds in your area. When left unchecked for long, debris can cause serious damage to your unit. For example, if debris is caught in the fan blades, this can cause the fan to become unbalanced and eventually break. Therefore, it is important you call an AC repair company to come and clean out your unit as soon as possible.

4. Lack of Lubrication

Lack of lubrication is another common cause of intermittent squealing noises from your AC unit. Different parts of the unit need to be lubricated to move smoothly. When these parts are not properly lubricated, they can start to make squealing noises. If you haven’t lubricated the different parts of an AC unit in a while, this could cause a squealing noise. You can try to lubricate the parts yourself, but it is best to call an AC repair company to do it for you. They have the proper tools and equipment to lubricate your unit’s different parts properly. Lack of lubrication is also a critical issue because it can cause parts to wear down more quicker, eventually leading to a replacement. It can also cause these parts to overheat and sometimes stop working completely. Therefore, if unexplainable shut-offs follow the squealing sounds, you should call an AC repair company as soon as possible.

5. Failed Bearing

Failed bearings are one of the most serious issues that can cause your AC unit to make intermittent squealing noises. The bearings help different moving parts rotate smoothly, so when they fail, these parts can start to grind against each other and create squealing sounds. In addition, failed bearings can cause these parts to overheat and sometimes catch fire. Therefore, if you think the squealing noise might be coming from a failed bearing, you must call an AC repair company immediately.

6. The AC Unit Is Not Level

If your AC unit is not level, this can also cause intermittent squealing noises. When a unit is not level, different parts can start to rub against each other and create squealing sounds. For example, it can cause fan blades to hit the housing, producing a squealing noise. It is important you call an AC repair company in Chandler, AZ, to level your unit as soon as possible.

If left unchecked, a unit that is not level can cause different parts to break or become damaged. For example, if the fan blades hit the housing hard enough, they can break and cause your AC unit to stop working completely. Therefore, if you think the squealing noise might be coming from a unit that is not level, you must call an AC repair company immediately.

Don’t Ignore the Squealing Noise Coming from Your AC Unit

If you hear a squealing noise from your AC unit, you must call an AC professional immediately. As you can see, different issues can cause your AC unit to make squealing noises. Some of these issues are not serious and can be easily fixed, while others are more serious and can cause extensive damage to your unit. Therefore, take caution and call an AC repair expert for diagnosis and fixing before any further damage is done.
