Why Is My Air Conditioner Making a Strange Noise?

One of the more common complaints that homeowners in the Central Florida area have with regards to their air conditioning systems relates to the system making a loud or unusual noise. While the system may appear to be functioning, an unusual noise can be alarming. Additionally, it can signal that something is not working properly and requires professional repair. There are a few common causes of a loud HVAC system.

Old Compressor

When an HVAC system’s compressor gets old or is close to wearing out entirely, it may make a loud noise. Some compressors can continue to function well for several months or more after the noise starts, but this is not always the case. To prevent a full breakdown, schedule an appointment for a diagnostic and repair service.

Broken Fan Motor

Although the fan motor in an HVAC unit is lubricated, this lubrication can break down over time. When this happens, the unit can make a funny noise when it operates. Re-lubricating the fan motor is usually not an option, so contact a professional for a fan motor replacement.

Damaged Fan Blade

A damaged fan blade can also make noise. Breaks can happen with age or if the fan blade comes in contact with the housing when the system turns on.  Avoid more costly repairs that can be caused by a broken fan blade shearing apart and damaging other components in the unit.   A broken fan blade will require a replacement rather than a repair, so contact a certified HVAC technician for options.
