3 Sounds Your AC System Makes When It Needs Repairs

July 11, 2022

Strange noises from an air conditioner are a warning sign that something is amiss. Don’t ignore the issue and deal with costlier repairs later. A noisy AC means that it’s faulty and requires urgent professional repairs. Here are some weird AC noises you might hear in your Pigeon Forge, TN, home and what they mean.

Loud Banging

Loud banging noises signify that you need an expert to check the air conditioner. An issue with the blower assembly could explain the loud banging noise inside your air conditioner or loose parts inside the blower assembly. Broken or loose parts can stress the AC motor, causing it to fail permanently.

Prompt AC repairs are paramount when you notice a loud banging noise to prevent costly air conditioning replacements. Turn off the air conditioner if you hear a banging noise and call for professional help.

Squealing Sounds

If your air conditioner produces a squealing or screeching noise, it’s a sign of a broken motor in the AC compressor. It could also indicate a faulty fan motor, bearings or fan belt. Deactivate your AC system if you hear a screeching or squealing noise and hire a qualified air conditioning expert for inspection and repairs.

Humming Noises

The contactor relay switch starts the outdoor condenser after receiving a signal from the thermostat. A defective contactor relay switch can cause humming noises, and it might be impossible to turn on the AC system. Hire a licensed service technician to inspect and fix the issue because ignoring electrical problems could damage your AC system.

Maintaining the AC system can prevent the problems that cause a noisy air conditioner. If you notice these AC noises, don’t panic. Schedule professional AC repairs. Call LB Chase Mechanical to learn about our preventative maintenance services and schedule an appointment with our experts.
