Always ensure that the water in the water tank is clean and free from impurities. Rare occasions of using mild additive agents for the purpose of freshening the air or for preventing corrosion are allowed. However, you should exercise caution when choosing such a cleaning agent. Regularly clean and replace the water if need be. If by chance the water tank is rusty, you should gently scrape off the rust and repaint using spray cooler coating.

3. Unplug the Cooler When Not In Use

Most of the time, your evaporative cooler will not be in use during the winter season. Therefore, it is best to clean the unit thoroughly and cover it to avoid the buildup of dirt. This will ensure that your unit is ready to resume work after the cold season has passed.

4. Clean the Water Pump
In general, cleaning the swamp cooler every 6 months is advised. Ensure that the water pump impeller rotates freely by manually turning it. Remove any debris by cleaning the pump screen. Call for evaporative cooler repair if you find that the pump shaft is stuck.

You can ensure the free rotation by manually turning the blower wheel and giving it some few rotations. Call for servicing if you notice the rotations are hard to make.

6. Adjust Float
The float should shut off the water at about ½ an inch below the top of the drain tube. Check and tighten any nut in case of leakages. If the float valve is not working properly, you can get an inexpensive repair kit to fix this problem DYI or get a trusted HVAC contractor to do it for you.

7. Corrosion Control
In hard water areas, it can be a good idea to install a bleed-off kit, which helps to minimize corrosion by flushing minerals out of the cooler. You can also do this by draining and refilling your reservoir at least twice a month or by adding a mineralizing agent neutralizer to help remove minerals from the water.
