Your AC should be virtually noiseless when functioning correctly – save the quiet sound of clean, filtered air entering your home. Squealing and screeching sounds indicate your blower motor is malfunctioning, your bearing has issues, or your belt is damaged and might break.

Rattling, banging, clanging, or thumping typically means you have a blower motor issue. It’s best to seek air conditioning repair immediately if you hear these sounds.

Something might be stuck in the blower, blades, or housing surrounding your unit if you hear steady clicking, smacking, or ticking. Ensure you’ve completely shut off your device before attempting to clear the blockage.

When your fan starts up, rattling indicates a failing motor or loose hardware inside the unit. Tighten any loose screws and call a professional air conditioning repair service to ensure that your access panels are correctly aligned.

Clicking when you power on or off your device means you have a relay problem, which needs comprehensive air conditioning repair or replacement.
