Clean air conditioner at home for better cooling

A few days back the air conditioner in my bedroom was not performing well and it was not cooling properly like before. We could feel the inefficiency of the air conditioner (AC). We were feeling the higher temperature though it was set at a lower temperature that is 18-degree cent. We bought it one year back and operated continuously for 2-3 months in the summer season and after that, it was not in much use when the monsoon started. We forgot or you can say missed servicing or cleaning of air conditioner filters. After one year when again the summer season arrived with annoying hot temperature then again we switched to the air conditioner (AC). Now the air conditioner was not cooling properly. Then we thought of cleaning air conditioner filters which might be clogged with dirt resulting in malfunctioning of the air conditioner. There are several reasons if air conditioner not cooling properly mentioned below.

Reasons for air conditioner not cooling properly

  • Dirty air filter clogged with dust blocking air flow.
  • Too high room temperature causing longer cooling process.
  • Improper circulation of air due to blockage (like curtain etc) in front of the air conditioner.
  • Open door or ventilation points in the room through which cold air is escaped. 

In our case, the reason for not cooling properly was clogged air filter with dust. So we followed the below procedure and cleaned the air filters.

How to clean the air conditioner at home for better cooling step by step:

  • Switch off the power of the air conditioner and remove the power cord from the plug.
  • Open air conditioner by lifting up the front panel from both sides.

  • Once all the dirt is removed then clean the air filter with water.
  • Now the air filter is clean. Keep it for drying.
  • Cleaning the air filter is the major part of cleaning air conditioners for better cooling. Other than air filters there are various parts also (like an anti-allergy filter, plasma filter, 3M filter depending on the model type) which need to be cleaned from time to time. Refer the corresponding manual of the air conditioner for better understanding of these parts. 
  • Wipe air conditioner with a dry cloth or a blower to remove the dust or dirt from other sections.
  • Clean the back side of the outdoor unit which is clogged with dirt using forceful water. Avoid using water on the front side of the outdoor unit.

We cleaned our air conditioner using this procedure and it helped. After cleaning, the air conditioner cooling is better like it was before. Maintenance manual says to clean the air conditioner air filter once in two weeks and now I will follow the same to avoid the poor cooling.
