Evaporative (Swamp) Coolers
Affordable, efficient cooling for the dry Antelope Valley climate.
Why Choose Evaporative Cooling?
In high-ambient desert climates, swamp coolers are useless. But here in the high desert, where humidity is often below 10%, they are incredibly effective. A modern Mastercool unit can lower the air temperature by 20-30 degrees for a fraction of the electricity cost of central AC.
Mastercool vs. Standard Coolers
- Standard (Aspen Pads): The classic metal box. Cheap to install, but requires new pads every year and frequent maintenance.
- Mastercool (Rigid Media): Uses thick 8-inch or 12-inch honeycomb pads. More expensive upfront, but cools much better, uses less water, and pads last 3-5 years.
Seasonal Start-Up & Shut-Down
Swamp coolers need love twice a year. In Spring, we connect the water, install new pads, and oil the bearings. In Fall, we drain the water, disconnect the line to prevent freezing, and install a cover to keep out drafts.
