Right now, the last thing on your mind is making sure your swamp cooler is working properly. It’s cold, so you’re more worried about heating your home. However, next summer when you turn your swamp cooler on, you’ll be praying cold air comes out. There will always come a time when your swamp (or evaporative) cooler breaks down. However, prepping your swamp cooler for winter can help your unit work longer, and more efficiently. Believe us when we say that one of the most common problems we see as a home warranty company is a lack of maintenance that causes major breakdowns. Winterizing your swamp cooler can save you thousands of dollars in repairs and replacements (that a home warranty might not cover).
