Protecting Evaporative Coolers During Arizona Monsoon Season

Every summer, the winds shift in Arizona. The hot weather creates low pressure zones along the desert floor that draw air and moisture up from the Gulfs of California and Mexico. This is the cause of Arizona’s monsoon season. Using an evaporative cooler during Arizona monsoon season requires some extra care. The storms last from June through September and can cause a lot of problems. Your cooler may not function right and it can get clogged with dust and debris. If you want to keep using them, here’s what you need to know.

Humidity              

Monsoons cause rain and thunderstorms all over the southwest. Places like Arizona experience sudden spikes in humidity and moisture that can interfere with the evaporative process. Evaporative coolers work best in warm, dry conditions, so whenever a storm occurs, their effectiveness drops.

Owners need to monitor humidity levels as best they can throughout the day. If they climb up close to 60 percent, it’s best to disable the cooling function and your evaporative cooler operate as an ordinary fan. All of the Luma coolers – the Luma Comfort EC45S, the Luma Comfort EC110S, and the Luma Comfort EC220W – have a fan mode. If humidity gets too high, the best way to use them is to place them in front of an open door or window and create a cross breeze. As their fans push air out the building, it draws more air in to keep you refreshed. Follow this link to learn more about evaporative coolers and home ventilation.

Haboobs

Another common feature of monsoon season are the dust storms. They’re called “haboobs,” Arabic for “blown,” and they occur whenever thunderstorms break and push out the air they’ve gathered. Wind speeds inside a haboob can reach 60 miles an hour and cover the ground in a foot of sand.

If dust gets sucked up into your cooler, it can stick to the cooling pads and prevent evaporation. Check the air flow from your cooler after a storm hits. If it’s sluggish, there’s probably been some dust contamination. To clear it out, remove the filters and cooling pads. Wash them out running water and then wipe down the water tank and the casing. You may also want to use a can of compressed air to get rid of any dust around the motor and fan blades.
