Why is your swamp cooler squeaking?

A swamp cooler may squeak due to several reasons, including worn-out or misaligned fan belts, loose components, or dry bearings in the motor. If the water reservoir is low, it can also cause the pads to dry out, leading to increased friction and noise. Regular maintenance, such as lubricating moving parts and checking for proper alignment, can help resolve these issues. If the squeaking persists, it may be best to consult a professional for further inspection.
