Why Is Your AC Making A Screeching Noise?

You’re not alone if you’ve noticed a screeching noise from your air conditioning (AC) unit. Many homeowners experience this issue, which can be annoying and concerning. As a trusted HVAC company, Green Guys Mechanical is here to provide the necessary answers. For comprehensive AC maintenance services in Ontario, NY, and the surrounding areas, look no further than Green Guys Mechanical. There are several reasons your AC may be making a screeching noise.

Let's Take A Closer Look At Some Of The Most Common Causes

Belt Issues: Many older AC units use belts to drive the blower motor or other components. These belts can wear out over time, become loose, or be misaligned. When this happens, the belts can slip or scrape against other components, creating a high-pitched screeching noise, similar to a car’s squealing belt. Belt issues can be caused by regular wear and tear or lack of maintenance, such as not replacing the belts as the manufacturer recommends.

Fan Motor Problems: The fan motor in your AC unit is responsible for circulating air throughout your home. If the fan motor is faulty or damaged, it can produce a screeching noise. This can happen if the motor bearings are worn out or if the fan’s blades are hitting against something, causing friction and resulting in the screeching sound. Fan motor issues can occur due to wear and tear, lack of lubrication, or dirt and debris buildup.

Compressor Troubles: The compressor is a vital component of your AC system that helps cool the refrigerant. If the compressor malfunctions or has internal damage, it can produce a screeching noise. This may indicate that the compressor is struggling to function properly, and the noise can be caused by the internal components rubbing against each other or due to excessive pressure. Compressor issues can occur due to wear and tear, electrical problems, or refrigerant leaks.

Refrigerant Leaks: Refrigerant is the substance that cools the air in your AC unit. A refrigerant leak can cause the AC system to work harder to maintain the desired temperature, resulting in increased pressure and stress on the components, including the compressor. This increased strain can lead to a screeching noise as the system struggles to maintain its regular operation. Refrigerant leaks can occur due to corrosion, aging components, or poor installation.

Blower Wheel Issues: The blower wheel in your AC unit pushes the cooled air into your home. If the blower wheel is dirty, clogged, or damaged, it can create a screeching noise as it spins against the debris or wears against the housing. Regular maintenance and cleaning of the blower wheel can help prevent this issue. Blower wheel issues can occur due to lack of maintenance, dirt and debris buildup, or normal wear and tear.
