How To Winterize A Swamp Cooler?

However, it is essential to winterize a swamp cooler before the cold winter months set in.
Below you go with the several steps to winterizing a swamp cooler.

Leaving these dirty can lead to corrosion of the coils over time, which will affect performance. Once the coils are clean, it’s best to blow dry them with an electric leaf blower to remove any remaining moisture. And allow the coils to dry thoroughly before sealing up the unit for winter.
If not properly cleaned, the coolant may mix with moisture, which will form clumps of frost on the inside of the unit leading to cause costly repairs. Thus a thorough cleaning process can eliminate this problem by sealing all potential leaks.
