An evaporative cooler, also known as the swamp cooler, can be used to keep your home or business cool in hot, dry places with low humidity. The box-shaped cooling device can be used to cool your home and is highly efficient in terms of energy consumption. Evaporative cooling systems are more efficient than conventional air conditioners, which use refrigerants to cool air. Instead, they rely on water evaporation to cool air. It also adds humidity.

Although evaporative cooling requires more maintenance and servicing than air conditioning, it is also cheaper to operate and maintain. This results in significant energy savings. You can make your evaporative cool last longer by choosing the right size and maintaining it properly.

Servicing Evaporative Coolers

Evaporative coolers must be serviced by professionals every year or bi-annually to ensure that they function properly and all parts are in great condition. This allows you to catch problems early and makes it easier to repair them quickly. Failure to attend regularly can result in costly repairs.

Usually, an evaporative chiller service includes:

  • Testing the drain valve or float valve
  • Complete unit cleaning
  • Inspection of switches and wires
  • Water pump testing and cleaning
  • Monitoring the water level within the reservoir
  • To ensure proper function, it is important to check fan operation, the airflow output, or filter pads.
  • The unit should be tested for correct operation and performance.

A professional check is not necessary. Homeowners should maintain a clean water tank and change any damaged cooling pads.

Many indicators indicate that your evaporative chiller needs to repair.

The Unit Fails at THE Start

Evaporative coolers that refuse to start indicate a problem. Most likely, the problem is caused by a blown circuit fuse. A blown fuse can also be the cause of system failure. An AC professional can replace the fuse. They will also inspect the wiring and determine the extent of the damage.

Poor Airflow

Airflow problems are usually the first sign of an evaporative cooling system. A blocked exhaust vent or worn-out metal parts can cause poor air circulation. To restore optimal functioning, a technician can clear the blockage or replace the damaged components.


It is a sign the evaporative chiller needs to be fixed if it begins leaking. It’s usually due to improper storage of the unit during winter. You need to drain the unit completely and remove any pads. Clean your tank. Cover the system correctly when you are not using it for an extended time. You should call a professional in order to identify and repair the source.

Foul Odor

The evaporative cooling system can become stale from water stagnation or mildew. It could be due to a lack of maintenance, stagnant water, or prolonged periods of standing water. You should contact a technician to find out the root cause and fix it. It is possible to cause serious damage to the evaporative cool and even pose a health risk by ignoring the issue.

Regular inspections, service, timely repairs, and regular maintenance by a professional can help your evaporative cooling system function efficiently, maintain comfort, and have a longer life expectancy.
