Evaporative Air Cooler Service: Cleaning, Checks and Repair

Use the manufacturer’s schedule and adjust checks to operating hours, water quality and dust. Inspect pads and the reservoir regularly during active use.

The manual may specify the reservoir, filter or pad, pump, float and exterior. Clean only components and with methods the manufacturer permits.

Dust or mineral scale can restrict pads and air passages, and a pump or water-distribution issue may affect operation. Inspect and service according to the manual.

Routine owner maintenance may be permitted, but electrical, plumbing and installed-system work should follow the manufacturer and applicable safety rules; use a qualified technician when needed.
