Evaporative Cooler Service in Grand Junction, CO
Startup, shutdown, pad replacement, and repair to keep your swamp cooler ready for Grand Junction summers.
Evaporative coolers need a bit more seasonal attention than standard AC: pads wear out, pumps fail, and a unit that sat all winter usually needs a proper startup before it'll run right. GPS Plumbing & Mechanical handles spring startup, fall shutdown and winterizing, and repairs for pumps, motors, and water lines in between.
If your cooler's blowing weak or musty-smelling air, it's usually a quick fix rather than a sign you need a new unit.

Evaporative Cooler Service questions
When should I start up my swamp cooler?
Usually in spring once nights stay above freezing and before the first hot stretch. A proper startup includes new pads when needed, a pump check, and clearing the water lines.
How often do evaporative cooler pads need replacing?
Often every year or two, and sooner if your water is hard and minerals cake onto the pads. Worn pads reduce cooling and can cause musty smells.
Why does my swamp cooler smell musty?
Old or dirty pads, stagnant water, and mineral buildup are the usual causes. New pads and a cleaning typically fix it. See our winterizing guide for fall care.
Do I need to winterize my evaporative cooler?
Yes. Water left in the lines and pan can freeze and crack parts. Draining the unit and shutting off the water supply each fall protects it.
Is the work warranted?
Our labor is warranted for one year. Parts and equipment are covered by the manufacturer's warranty. We do not cover or offer a warranty on customer-supplied material or equipment.
