Air cooler problems and Solutions

Air Cooler Problem and Solution: Dirty Filter

A dirty air filter causes the air cooler to work harder, which increases wear and tear on the fan and causes the motor to overheat. A dirty air filter is one of the common problems of an air cooler.

A dirty filter blocks the air and also fails to filter the air.

Something that has been on my mind lately, and I have a feeling many others are experiencing the same thing, is dirty air cooler filters. It’s well known that when these filters aren’t often cleaned they can cause a variety of problems for homeowners, from causing allergens to build up in your home to even clogging your air conditioner unit.

Many people may have heard about this before, but just didn’t realize how easy it was to clean an air cooler filter. 

You should clean the filter with detergent and water and then leave it to dry.

You should clean the dirty filter with water and some regular detergent every 15 days.

Air Cooler Problem and Solution: Water tank Leak

Air coolers are used to draw fresh air from outside the building into an enclosed space where it can be cooled by passing through a cooling medium. They are particularly prevalent in homes, shopping malls etc.

The first thing that may cause spilling is simple over-filling of water—this will result in a messy accident until it evaporates on its own! So keep watching the water meter while you are filling the tank.

There could also be more serious causes for spillage such as leaks from either the tank not being fastened properly or broken connections due to rust around fittings which has resulted in small holes.

You can plug those holes with an m-seal, but before application make sure surfaces under sealer have been thoroughly cleaned and dried out!

For the water tank, you should be adding distilled water every 15 days into the tank so that all impurities get washed down as well as any dirt from previous use.

It’s unfortunate that not all air coolers are perfect. There are often problems with the device, such as a foul smell, which can be difficult to fix. Here is what you should do if your air cooler has an issue:
