Squealing

A high-pitched squealing noise can indicate a few issues. Some AC units rely on a belt to drive the fan. When the belt becomes worn out or broken, it can make a squealing noise. Bearings can also cause a similar sound. In either case, the squealing means your AC system will fail soon if you don’t obtain repairs.

Hissing

A hissing sound typically means that something is wrong with your AC unit’s refrigerant cycle. There could be a refrigerant leak at any point in the line, and you’ll need a professional to find it. The compressor valve is one of the most common points, with the high-pressure release creating a distinct hissing sound.

Clicking

You might notice a clicking noise during cycling as switches flick inside the AC. However, constant clicking is a sign that something is wrong. Rapid clicks likely mean an obstruction to the fan or other damage. There could also be electrical faults affecting switches.

Whistling

If your home has ductwork, a whistling or blowing noise is likely caused by a leak. That means you’re wasting additional energy cooling wasted air. There could also be an obstruction to airflow, which again causes efficiency issues.
