Especially in hot and humid areas as well as polluted cities, air conditioners have become an important part of our homes (read our AC Buying Guide For India). It is during the summer that air conditioners are most commonly used, and at that time you would want your air conditioner to be in perfect working order so that it doesn't fail or break down when you need it most. Each air conditioner, whether it is a split air conditioner or a window air conditioner, can break down and develop problems if not properly serviced. In this article, we will discuss the most common split air conditioner problems and possible solutions.

How to Fix the Most Common Split Ac not cooling Problems

The most common split AC problems are caused by irregular maintenance, and most of those problems could be prevented.

There is a lack of cooling

Cooling down the room to the required temperature does not take long with split air conditioners. It definitely has some issues if your Split Ac not cooling as fast as it used to despite being on for hours. If your air conditioner isn't cooling, it could be due to a dirty air filter, a blocked condensate drain, or ice building on the evaporator coils.

Air filters that are clogged

Air filters are designed to protect the AC from dust, debris, and hair. If they are not cleaned frequently (once every six months), they can become clogged and affect the AC's cooling performance. In addition, clogged filters increase electricity bills and slow down cooling, as they force the AC to work harder (and consume more power) to cool the same room. In order to clean or unclog an air filter, you should remove it from the split air conditioner (check your AC's manual for instructions) and clean it using a low-power vacuum cleaner or warm water.

For better performance and to avoid clogged air filters that result in slower cooling and higher electricity bills, have your air conditioner serviced twice a year.

Evaporator coils ice up

It is also possible that ice is forming around the evaporator coils, which could be causing the lack of cooling. If you do not maintain your AC regularly, ice can form on its evaporator coil, which also leads to dirt, dust, and fungi collecting on its air filter and other parts. An ice sheet on the evaporator coils slows down the AC's cooling performance when it is unable to absorb latent heat. The problem should go away if you clean your air filters regularly. If it doesn't, we recommend calling an experienced service professional for assistance.

A split AC's evaporator coils can also form ice when the refrigerant level drops due to gas leakage.

It is also possible that ice is forming around the evaporator coils, which could be causing the lack of cooling. If you do not maintain your AC regularly, ice can form on its evaporator coil, which also leads to dirt, dust, and fungi collecting on its air filter and other parts. An ice sheet on the evaporator coils slows down the AC's cooling performance when it is unable to absorb latent heat. Make sure that you clean the air filters at regular intervals. Most people should be able to resolve this issue with regular air filter cleaning, but if not, call an experienced service professional.
