Are you contemplating purchasing evaporative coolers in Phoenix, AZ? First, let’s review what these pieces of equipment do. Then, since colder weather is on the horizon, we’ll offer tips on how to prepare your new evaporative cooler for winter.

What is an evaporative cooler?

An evaporative cooler is a piece of equipment that cools the air through the water evaporation process. Specifically, during the evaporative cooling process, which differs from traditional air conditioning systems that use a vapor-compression system, water vapor is added into the air, resulting in a lower air temperature.

An evaporative cooler can be especially effective in dry climates, such as what we experience in Phoenix, as it conditions the air with more moisture than a traditional air conditioner. An evaporative cooler is also more energy efficient than an air conditioning unit.

How should I get my evaporative cooler ready for winter?

It’s likely you won’t need to use your evaporative cooler all year round. Take a look at the tips below to learn what to do before winter hits to ensure that your equipment will be in good working order once summer is here again.

First, turn off the power supply before you begin the winterization process. Then, follow these steps:

  • Shut off the valve that provides water to your evaporative cooler: This will ensure that freezing does not occur during the winter. You’ll also want to disconnect the water line at the supply valve and the evaporative cooler. If you notice that the water line does not rest on one level plane, you will need to perform an additional step to drain the water. At the highest end of the slope, blow through the line to push the water out.
  • Remove any debris: Drain your evaporative cooler and leave the drain open so that any rain that falls during the colder months can escape through the cooler. You will likely notice that dirt and minerals remain in the bottom of the pan. You can clean these out by using a device such as a shop vacuum and then running fresh water through the pan to make sure all debris is gone.
  • Replace the cooling pads: Performing this task before winter arrives will help prevent rusting from occurring during the winter.
  • Install a cover for the evaporative cooler: A cover will prevent outside air from the evaporative cooler from entering your home. While most coolers will have a damper, which you can close to stop air from entering the ducts and making its way into your home, not all coolers have this feature. Alternately, if your evaporative cooler does have a damper, it may not be tight enough to prevent outside air from coming in.
