Preparing Your Swamp Cooler for Winter


If you own a swamp cooler in the local area, then you need to make sure that you take proper care of it to make sure it works properly when you need it. That is why you should winterize your swamp cooler. When the winter months roll around, you are not going to use your swamp cooler as much.

As a result, it is going to sit idle until the temperatures start to heat up again. When the swamp cooler sits around for a while, it might end up causing problems that could lead to issues not only for the swamp cooler but for the home as well. Therefore, it needs to be properly winterized.


Why Should I Winterize My Swamp Cooler?

When the winter rolls around, the swamp cooler is not going to be used for a while. Therefore, it is important to power it down and protects it from the winter appropriately. The first reason why people need to winterize the swamp cooler is that this is going to protect it from harm.

When someone going through the process of winterizing their swamp cooler, they are placing it in a position to ride out the winter months without collecting dust, debris, and damage. Some of the most common examples of how a swamp cooler might be damaged during the winter include mold, mildew, rust, and broken power lines.

The second reason why people need to winterize the swamp cooler is that this will protect the home as well. If the swamp cooler is damaged during the winter, this could lead to water leaks that might damage the home.

Furthermore, if the swamp cooler has an open vent, this could end up causing the house to lose heat to the outside. This could drive up the utility bills during the winter. Therefore, it is important for everyone to winterize the swamp cooler appropriately.

What Are the Benefits of Winterizing a Swamp Cooler?

There are several benefits that are going to come with winterizing a swamp cooler. Some of the main benefits of this process include:

  • First, winterizing a swamp cooler will help prevent a water line from freezing. If the water line freezes, then it could end up bursting. Therefore, the water supply valve of the swamp cooler has to be turned off

  • Next, winterizing a swamp cooler will also prevent the growth of mildew and rust. The base of the cooler has a lot of standing water and if this can sit there, this could lead to the growth of mildew and rust.


  • When the swamp cooler is winterizing properly, the amount of heat that is lost through the unit will be minimal. Closing the vent or putting a vent cover on it will help keep the heat inside the home during the winter.


  • If the swamp cooler is winterized properly, then it will be protected from the elements. If the swamp cooler has been exposed, this could cause dust and debris to build up on the motor and in the ducts.


  • Finally, when the swamp cooler has been winterized properly, this is going to extend its life by protecting it and the home from damage during the winter. As a result, homeowners will not have to replace their swamp cooler as soon.


These are just a few of the biggest benefits that come with winterizing a swamp cooler. By making sure the swamp cooler is ready to ride out the winter months, people are also making sure that it is ready for the summer as well.

What Do I Need to Do to Winterize my Swamp Cooler?

When it comes to winterizing a swamp cooler, it is important to do this properly. There are several steps that people are going to need to follow to winterize the swamp cooler.

  • First, it is a good idea to look at the valve that is supplying water to the swamp cooler itself. Shut off this valve to make sure that it does not freeze during the winter. Furthermore, it is a good idea to disconnect the water line where it meets the supply valve and the evaporative cooler.

  • Once this is done, leave the drain open to make sure that any rain that falls in the swamp cooler itself is going to drain out. Once the water is gone, look at the inside of the swamp cooler and clean out any dust and debris. A shop vacuum and a bit of running freshwater will take care of this debris and prevent mineral deposits from building up.


  • Replace the cooling pads as well. This will prevent rust from developing in the swamp cooler during the winter. Finally, install a cover for the swamp cooler itself.


A cover is going to prevent outside air from entering the home. If there is a damper on the swamp cooler, then it might be possible to close this as well.

By taking care of these steps, everyone is going to place their swamp cooler in a position to ride out the winter months in a safe environment. Then, the swamp cooler is going to be ready to go when people need it for the summer months once again. This can prevent damage from occurring both in the swamp cooler and in the home itself.
