Conventional swamp cooler pads
Single inlet cooler pad
Why does my Spring changeover cost more than my Fall changeover?
The answer is simple: more parts go into a Spring changeover. Usually for the Fall, the only thing that needs to be replaced is the filter on your heater. Sometimes cooler parts need to be replaced if they are broken or worn down, but generally only the heater's filter is replaced. In Spring, the pads on the cooler are changed and the waterline is replaced, as well as other parts that can include nuts, ferrules, the belt, and the float.
Frequently Asked Questions
What is the difference between a single inlet evaporative cooler and a conventional swamp cooler?
A single inlet swamp cooler uses one thick pad as opposed to a conventional cooler, which uses four smaller pads. The smaller pads of a conventional cooler need to be changed at least once per year; sometimes even more frequently if there is a lot of hard water. A single inlet cooler needs its pad changed after a few years of use, and cools 3-5 degrees cooler than a conventional cooler.
