How to Shut Down Your Evaporative (Swamp) Cooler for Winter

Evaporative coolers (sometimes known as swamp coolers) are really common in our area because the typically-dry air actually makes them an ideal cooling installation. With too much humidity in the air, they won’t work properly, but in our climate, they tend to be efficient, durable, and the ideal cooling installation.

But when winter comes, you must get your evaporative cooler ready in order to prevent freezing, mold, and damage to the system that may mean more work and money for you in the spring. This also helps your evaporative cooler to last longer. Here’s what you should do:

  • Shut It Off – Don’t just turn it off. Unplug the power supply to make sure it doesn’t start up by accident in the winter.
  • Cut Off Water Supply – Shutting off the water valve that leads to the evaporative cooler is the first step. We also recommend that you drain the hose that moves water in. If there is water left inside, it can freeze, causing the hose to expand and contract which can damage it and lead to leaks. Many people recommend blowing in it to drain it.
  • Drain and Clean the Tank – Now you’ll have to drain the tank which should have a drain located at the bottom. You’ll need a toolbox to get this open; it usually requires pliers or a wrench. And you can soak up the remaining water with a rag, as this helps to prevent mildew and mold. If you notice mineral build up, try soaking the pump in vinegar.
  • Cover It – We recommend covering the swamp cooler and tying it down, as well as sealing the vent leading into the home with some sort of damper.
