- 1Hot, dry outside air is pulled into the cooler through its side pads.
- 2Water soaks the pads A small pump keeps them wet. As water evaporates, it takes heat from the air.
- 3Cooler, moister air is blown down a short duct into the house.
- 4An open window lets that air leave. With the house shut, the cooler cannot push air in.

Why coolers fit here
Built for hot, dry afternoons
The Department of Energy says evaporative coolers work well where air is hot and humidity is low. Grand Junction is a semi-arid valley, and the NOAA normals show it.
- Days at 90 F or more, per year
- 64.5
- National Weather Service station digest
- June average humidity
- 22.8%
- The driest month in the NOAA normals
- July average high
- 94.5 F
- 25.6 days at 90 F or more
- Energy vs central air
- About 1/4
- Department of Energy, 2011 guide
Humidity climbs in July and August, so late summer brings more days when any evaporative cooler struggles. See the month-by-month comparison with refrigerated air.

Towns across the valley
Each town page has what is different there: the water provider, the permit office, and the neighborhoods it covers.
The ground rules
Safe checks, then a clear stop
Safety first. Roof work, the inside of the cooler cabinet and anything electrical are jobs for a cooler technician. Every check on this site is done from inside the house or standing on the ground. Nothing here asks you to climb a ladder, open the cabinet or touch wiring. If you see smoke, sparking or fire, get everyone out and call 911.
Honest availability. GJ Swamp Coolers has no published hours and does not promise a response time. Mark a request urgent and say what is happening, and protect the house first.
