We had to remove the side-mounted evaporator cooler from the rear of the house because this location is the future space of the master ensuite addition.
These coolers are commonly referred to as swamp coolers or desert coolers. The device cools air through the evaporation of water. Evaporative cooling works by employing water's large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor, which requires much less energy than refrigeration. Unlike refrigeration, it requires a water source, and must continually consume water to operate.
We posted the swamp cooler on Craigslist in the free section. We had 9 phone calls in 30 minutes. I had to delete the Craigslist posting to stop the calls. I guess we should have asked at least $100.
A retired Canadian contractor came over and removed it from the building, which included disconnecting the electrical, plumbing and duct work. Giving it away saved us money from paying our general contractor to remove it, and we feel good that it will go to another home instead of a landfill.
In lieu of using an evaporator cooler, we plan to add insulation into all of the home's hallow walls.
