Why Your AC System Is Making So Much Noise

An air conditioner should be relatively quiet. If you’ve noticed your AC system in Port Wentworth, GA, making more noise than usual, it could indicate one of several problems. Here are some common AC noises and what they mean:

Banging Noise

A loose compressor or fan motor part usually causes banging noises. This can be due to normal wear and tear or an installation error. If you hear this sound, turn off the system immediately and call for professional AC maintenance.

Gurgling Noise

If your AC system makes gurgling noises, this could indicate a refrigerant leak. Refrigerant is essential to the cooling process and must be at the proper levels. If it’s leaking, your AC system will struggle to cool your home efficiently.

Humming Noise

Worn-out wiring or loose connections can cause your AC system to make a low humming noise. Some humming noises result from electrical problems, such as faulty circuit breakers or wiring issues. If there is a burning smell, turn off your AC system and call us immediately because there may be a fire hazard.

Squealing Noise

Squeals in the duct system can result from a loose or broken belt, worn-out bearings or a damaged fan motor, indicating airflow problems. Sometimes the sound may be normal, especially when the system first starts up, but it should stop after a few minutes. Schedule an inspection to avoid further AC system damage.

Rattling Noise

A rattling noise from your AC system can indicate loose hardware or screws. Rattling also suggests that you may need to replace the fan blades or the blower wheel.

If your air conditioner makes any of these noises, take immediate intervention. Contact Old Coast Heating & Air Conditioning for AC repairs or a tuneup to ensure the system works efficiently. Our service technicians will diagnose the problem and repair your system before it worsens.
