Is Your AC Blower Fan Making a Strange Noise? DIY Diagnostics

A noisy indoor unit can keep you awake at night. Rattling, clicking, or vibrating sounds are common signs that something is loose or out of balance inside the blower assembly.

What to Check

Verify that the front grill panel is fully closed and locked in place. Check if filters are bent or loose. Look inside the blower wheel using a flashlight to ensure no debris or dry leaves are trapped.

When to Call Lourds

If the noise persists, it could be a worn-out fan motor bearing or a cracked blower wheel. Lourds Aircool stock genuine replacement parts and can restore quiet operation in under an hour. Call us to book a repair visit.
