How To Maintain Your Evaporative Cooler
Evaporative coolers are a great, low-cost alternative to air conditioning, particularly in arid climates. In addition, since many evaporative coolers are mechanically-simple, you can perform maintenance yourself with just a little know-how. Here are some essential maintenance tasks that you should do to keep your unit running smoothly: Pad replacement and cleaning Evaporative coolers use pads that become saturated with water that continuously recirculates inside the cooler. This water trickles down through the pad material, while incoming air flows through the wet pads; the hot, dry air is cooled by evaporation, and a fan forces the cool, moist air into the home.
