Winterizing the evaporative cooler saves maintenance and repair costs during summers and spring. Furthermore, it also increases the lifespan of the system. But why shut it down for the winters?
Remember that physics class in the 6th or 7th grade where we learned about the harmful impact of standing water? From mildew and mold development to corrosion and rust –the effects were long-lasting and costly. Not to mention, how the freezing of water expands and bursts the pipes and causes additional expenses.
To avoid all that from happening, this article will help readers to shut down their evaporative coolers themselves without having to call a professional. Let’s start.
Cut Off the Power Source
Since you won’t need any of the evaporative cooler’s assistance during winters, it is best that you switch if off. This is the first step to shutting it down. Doing so will increase the level of safety as you move on to the next steps.
Clear the Water Pipe
Next, drain any standing water in its base. The pipes, valves and water pan at the bottom must be clear of any moisture or dampness as we have already discussed how ponding can harm the appliance and add to your repair and maintenance costs. Use sponges to get rid of that last drop of water and leave the system open so that any remaining water can dry.
Clean the Cooler
The next step involves the cleaning of the sides of the vent off any dirt and debris that may have latched onto it. A shop vac can also be used in case of excess dirt. The pressured air will blow away and dirt, especially from the vent.
Change the Pads
Moving on, change the pads of the evaporative cooler. Most people like to change the pads during the winterizing process. This allows them to begin using their evaporative cooler right away during springtime. This allows for a quick hook up of the water pipe and the system is good to go. However, this step is completely optional and can be postponed until springtime.
Buy an Evaporative cooler cover
Next, invest in an evaporative cooler cover. A cover will protect the system from many unwanted elements during winters such as rain, fog, and snow. Leaving it uncovered can easily allow water to enter the unit and create a swamp. This will damage and critical wiring and also jumpstart rusting.
Evaporative cooler covers are cheap and easy to install. They simply fit snugly over the unit with multiple threads that can be tied down to prevent it from sun rain, dirt, and snow.
Cover the Vent
The final step to winterizing the evaporative cooler is covering the vent. Leaving it opens can lead to the loss of possible heat from inside the house. This will overburden your HVAC unit and expect it to perform better and ultimately increase your utility bills. Covering the vent will limit the blowing of air inside the house so that it remains sealed and warm throughout the winters.
