Unlike air conditioning units which use refrigerants, evaporative coolers cool through the natural process of evaporation. As the water vapor evaporates, it takes heat with it, cooling the surrounding air. The process also removes humidity and leaves a fresher, more comfortable environment. As a result, evaporative cooling repairs is more effective in dry climates and uses only about a quarter of the energy that A/Cs require to operate.

What is the cooling maintenance?

However, evaporative coolers still need regular maintenance to keep them in good working order. Those repairs should include cleaning the cooling pads, emptying and refilling the water tank, examining the fan for any signs of wear and tear, and testing and oiling the motor and recirculating pump. Ideally, homeowners should have their swamp coolers professionally serviced before the start of the cooling season and again halfway through summer.

If a swamp cooler is not cooling, the most likely problem is blocked air flow. This can be caused by a clogged filter, dirty pads or too much dust. Alternatively, the fan may be failing to turn, possibly due to a broken motor, a ruptured pulley or a loose fan belt.

It is recommended to drain and scrub the water reservoir, scrub the pad surfaces with a brush and a mild soap solution or plain water, check the pump for any leaks and clean the filters. In addition, it is essential to make sure that the power switch in the house is turned off and to disconnect the electricity at the evaporative cooler. A ladder and harness should be used when servicing a roof-mounted swamp cooler, as it is unsafe to work at heights without one.
