If you live in a hot climate, you know that an AC is a must. Unfortunately, when an appliance gets used as often as your AC, problems may arise. One of the issues is when your AC starts to make squeaking noises, which can be incredibly distracting or annoying.

Air conditioners consist of several components, which include the compressor and blower motor, the evaporator coil, and the condenser coil. Because these components work together, they may wear out over time. Here are five common reasons why your AC may be making squeaking sounds.

1. The Fan Belt Is Worn Out or Misaligned

The fan belt is an essential part of an AC system. Without it, the electricity that powers your AC would not reach the compressor. A fan belt can wear out or become misaligned because of its age or if has been damaged. When a fan belt wears out, it makes a squealing noise when it spins because the belt is aligned incorrectly on the AC’s pulley system, which causes squeaking noises.

2. The Bearings Are Worn Out

Your AC has bearings that keep the fan in place. These bearings can wear out over time and cause a lot of noise. When the bearings wear out, the fan starts to wobble and squeak as it rotates because it cannot stay in position. The most common cause of worn-out bearings is damage from corrosion.

3. Your Compressor Is Failing

If your AC starts to make a loud noise, there is a good chance that its compressor is failing. The compressor can get old and worn out, or the bearing and belt could be damaged. In either case, the AC will no longer be able to produce cold air. If your compressor has failed, it will tend to make the same squeaking noise as a fan and belt. The sound of bearings on an AC-driven fan can be similar to the sound produced by a broken air conditioning unit.

4. The Refrigerant Is Leaking

The refrigerant that is used in air conditioning is a highly pressurized substance. If it was improperly installed or if there was a leak, the refrigerant could start to escape out of the AC. If your AC has leaks in the tubing, you might start to hear strange noises coming from your system. A leak can also cause the refrigerant to escape into your room and overheat, causing another noise. If your AC leaks, you need to call an HVAC repair service to address the problem because refrigerant is toxic. Do not attempt to repair it yourself as this could put you in serious danger.

5. The Blower Motor Burned Out

The blower motor is a vital part of an AC system because it delivers cold air throughout your home. If it starts to fail or the bearings and belts wear out, you will start to notice strange noises. When the blower motor burns out and falls apart, it can also produce a squeaking sound as the pieces move around in the system. Make sure that you have someone check your AC if you notice strange noises coming from inside of it.

A malfunctioning blower fan can make a variety of strange noises and sounds. These can include a low humming, buzzing, whining, or squeaking sound. If your blower fan makes these noises, the motor is wearing out and needs to be replaced.

Faulty parts can lead to an AC that will not cool your home. They can also be disruptive to your day because they could make a lot of noise. It is crucial to have a professional check out your AC if you notice strange noises. There are many reasons why an AC would produce strange noises, and all of them should be addressed right away.
