For many people, a functioning air conditioner is essential for comfort during the hot summer months. But when something goes wrong with your ac unit and it starts producing an annoying squeal, it can be extremely frustrating.
Fortunately, there are steps you can take to identify the source of the sound and repair or replace parts as necessary so that your system runs quietly again. Read on to find out more about why outside ac units squeal and what you can do about it!
Causes Of Squealing Sounds
We’ve all heard it – a loud, shrill squeal coming from the outside of our home. Whether we’re relaxing in the living room after a long day, or just getting ready to go to bed, it’s an unwelcome distraction.
But what causes this ac unit squeal?
The most common cause of ac unit squealing is due to a worn-out motor bearing. Over time, the bearings that support the motor shaft start to wear down and eventually fail, causing vibration and a high-pitched noise.
This can be especially noticeable at night if you have your windows open and the sound is carried into your house.
In other cases, the cause of the squealing sound could be due to debris stuck inside the fan blades. This can happen when leaves or other debris get sucked into the fan blades and then become lodged there, preventing them from spinning freely and causing a high-pitched sound as they scrape against each other.
No matter what caused it, dealing with an ac unit squeal is not something anyone wants to do – especially not in their own home. Thankfully, there are some troubleshooting tips we can use to help identify and fix this issue quickly.
Troubleshooting Tips
Now that you know what could be causing the squealing noise from your outside AC unit, it’s time to troubleshoot. There are a few easy fixes you can try before calling an HVAC technician.
The first thing to do is check for any debris or dirt buildup around the fan blades and coils. If there is any build-up, use a vacuum cleaner to remove it from the fan blades and coil fins.
This will help ensure that air can freely flow around the system. It may also alleviate the squealing sound if it was caused by debris accumulation.
Another simple fix would be to lubricate any moving parts with a lubricant specifically designed for HVACs. This includes things like bearings and joints in drive motors, blower fans, and other components that could potentially cause a squeal if they are not properly lubricated. Make sure to follow the instructions provided by the manufacturer when applying any lubricants to avoid potential damage or injury.
Once these steps have been taken, you should be able to tell if there are signs of damage or wear and tear that need further attention from an HVAC professional. If so, then contact an expert right away as ignoring the problem could lead to future issues with your AC unit down the line.
Signs Of Damage Or Wear And Tear
Squealing coming from an outside AC unit can be a sign of damage or wear and tear. After all, it is exposed to the elements, so it’s bound to suffer from some issues along the way.
Here are some signs of damage or wear and tear that could be causing your AC unit to squeal:
- Loose fan belt
- Debris caught in the fan blades
- Worn out bearings in the motor

These are all difficult problems to diagnose and fix without professional help. Even if one of these issues is causing your AC unit to squeal, it could require special tools or experience in order to make the necessary repairs.
Before you call a specialist, make sure you check for any visible debris around the outside of your unit. If that doesn’t solve the problem, then it’s time to bring in a professional.
