What to Do When Your HVAC Unit is Making Noise

If you hear any unusual noise coming from your HVAC unit, please turn it off and call us. Don’t attempt any kind of repair without consulting an HVAC certified technician first. Call Precise Comfort and Climate Specialists, Inc. at 504-273-0522 or contact us online if you hear any of the following noises:


This can indicate that you need a new motor bearing or have a bad belt. Belts are a relatively cheap fix and often your motor just needs lubricating. This can be done at home or by a professional. Call our office at 504-273-0522 for more information.

Rattling/Thumping/Banging/Clanking from the Inside

Usually this means a problem with the blower or the motor. This can indicate that a part inside your heating unit or air conditioner has come loose. If the noise is louder than a rattling and more like a banging noise, you probably have a part that has broken or disconnected completely. At this point, turn your unit off and call our office.


If you hear a scraping noise, turn your unit off. This can indicate a dangerous situation. This sound usually means that something has broken completely and is moving around the inside of your unit.


If your unit is working the way it should, than this is probably just the transformer running loudly. If your unit isn’t working properly, this might be the motor fan or capacitor.
