Evaporative (swamp) cooler service
Evaporative coolers work well in dry desert air but need regular care: new pads each season, a working pump and float valve, a tight belt, and clean water. Startup in spring and drain-down before freezing nights keep them reliable.
- Same-day appointments when available
- Licensed HVAC contractors
- Written price before any repair
Evaporative coolers are common in dry Western climates such as Arizona, New Mexico, Nevada, Utah, Colorado and West Texas, where low humidity lets them cool efficiently. Hard water in many of these areas builds scale on pads and pumps quickly.
Swamp coolers lose effectiveness when humidity rises, such as during the Southwest summer monsoon. A cooler that never feels cool on a dry day usually has dry pads, a dead pump or a slipping belt.

FAQ
Evaporative (Swamp) Cooler Service questions
Can I use a swamp cooler with central AC?+
Yes, many Western homes have both. Use the cooler on dry days and switch to AC during humid weather. Never run both at once with the cooler damper open.
How often should evaporative cooler pads be replaced?+
Aspen pads often need replacing every season in hard-water areas. Rigid media pads can last several years with a bleed-off kit.
