Ways to Prevent Your Air Cooler from Getting Damaged

Last updated Nov. 24, 2017

Even though evaporative air coolers are sturdier than the standard air conditioner, they still break down and get damaged. No machine is perfect, and all sustain damage after a while.

To be able to prevent breakage to the system there are necessary care and maintenance procedures that need to be taken. There is nothing worse than losing your source of cool air on a hot and dry day.

Evaporative air coolers are very low maintenance and there are steps that can be taken as preventative measures to ensure that your system will remain running at optimum performance throughout the hot season. Here are a few tips to clean and maintain your air cooler to try to keep it running powerfully smooth.



Most of the problems caused in the air cooler are due to dirt build-up. Evaporative air coolers need to be cleaned once or twice a year. Many owners haven’t cleaned their coolers for years and it really affects the system’s performance. To perform a simple cleaning:

  • Turn off your system and unplug it from the wall.
  • Using a clean cloth, wipe down the fan blades.
  • Remove the pads and run them under water to clean away all the dirt. You can use a mild dishwashing detergent in a small amount, as well. There are also air cooler cleansers on the market that you can use if desired. After the pads are cleaned, lay them out to dry thoroughly before they are placed back into the system. If they look frayed or torn they may need to be replaced with new pads. Now is the time to do so.
  • Remove the water tank and clean it under running water. Wipe it dry.
  • Make sure all components are cleaned and dry before assembling your system again.



Apart from keeping the system clean you also need to keep the motor well maintained. This is easy to do with an air cooler. Check all wiring. There shouldn’t be loose wires. Check to see that the switches are tight and there aren’t any water leaks coming from the system, tank or pipes used.

Is the insulation in good condition? These things can be quickly checked to ensure your system is working properly.

Most problems can be handled by the homeowners themselves and other more serious ones might need professional help if the damage is extensive. One of the most common problems associated with this type of damage is damage created by a dry run.  



Evaporative air coolers use centrifugal action to pump the water. The pump is not operated on oil or grease to keep it working. It relies solely on water. Dry run is when the water stops flowing into the pump. When this happens, friction builds up within the other internal components. This built up friction will begin to wear down the other components causing major damage to the pump.

This wear is caused by overheating and accelerated friction. Dry run pumps are a common problem, but the good news is that they are entirely preventable. It happens when the tank runs out of the water. When the tank runs out of the water it has nothing to send to the pump which then runs dry.

Water acts as the lubrication for the pump. Without the water, the pump will continue to run but will build up friction and overheats which causes damage. It is a simple thing to keep an eye on the water level in the tank.

There are several ways to accomplish this and make the chore convenient for you. Here are a few ways:

  • Larger Reservoirs: Evaporative air cooler owners can purchase an air cooler with a larger water tank depending on their needs. This allows for more water to be stored and less of a chance of dry run damage.
  • Continuous Water Supply: This option allows you to hook up the pump to your water tap. The only warning with this method is to keep the water flowing in the tap. If the tap is shut off, then it can cause damage to the pump in very little time.
  • Automatic Indicator: Air cooler models like these also come with an automatic indicator that will fill the water when the level gets low. Others monitor the water levels and will alert you when water levels get dangerously low.
  • Automatic Shut Off: This is a new feature that saves a lot of wear, tear, and concern. The automatic shut off will shut the system off when the water level is low preventing damage. This way the owners will not have to worry about their system as the smart inbuilt technology will prevent the damage.

Evaporative air coolers are the most efficient cooling systems on the market. They are easy to use and easy to repair. It is also easy to prevent damage to the system. Air coolers are pretty robust and can work sufficiently for years to come with regular maintenance and cleaning.

Newer models are just as reliable as the new state of the art technology that makes the operation of the cooler even more convenient and nearly damage free.

The evaporative air cooler is a sturdy system and works on natural energies of water and air. Air coolers are monumentally less expensive to purchase than air conditioners. They also cost massively less to use.

These systems break down less frequently than air conditioners and they cost less to repair as they are composed of a simple system that the owner themselves can fix.

The air cooler is the best there is for cooling the air in the home or business especially in areas that experience hot and dry weather. The system is full of benefits and modern technology producing clean and cool air all year long.
