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 252-247-5500 or contact us online 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 furnace 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.
