Cleaning of the home air conditioner with your own hands

Air conditioners in apartments and offices have become a natural attribute of a comfortable life and work. But it is worth remembering that the air conditioner is a technically complex device that needs regular maintenance. The only thing you can do for your split system at home is to carry out a comprehensive cleaning and disinfection.

But the outdoor unit can have its own difficulties. However, in this article we will tell you how to clean the split system at home, and do it with maximum benefit.

General information

The more technologically advanced the device, the more attention it requires. And air conditioners are no exception. They require regular maintenance, which must be carried out at least twice a year if you use the unit only in cooling mode, and four times a year if the split system is operated in heating mode.

Most of the work can only be done by a professional, but you can also do something with your own hands. For example, get rid of dirt, dust and mold in the interior of the air conditioner.

If you regularly use the device and have never cleaned it, it’s time to open the air conditioner with your own hands and perform a number of simple tasks. If you ignore them, sooner or later you will have to call the service. It is for this reason that it is so important to know how to clean the air conditioner at home yourself. After all, it is not always possible and willing to invite a third-party specialist to solve problems.

Next, we will tell you in detail how to clean the outdoor and indoor unit of your split system yourself.

Cleaning the indoor unit

Preparatory work

Cleaning air conditioners with your own hands begins with the indoor unit. Usually it is installed directly on the wall, it is difficult to confuse it with something. Let’s figure out how to clean the indoor unit of the air conditioner yourself.

To clean the indoor unit, you will need a small set of tools that can be found in any apartment:

  • Soft cloth, sponge for washing dishes, brush;

  • Warm water;

  • Wide deep water tank;

  • Disinfectant for air conditioners;

  • Vacuum cleaner and a narrow nozzle;

  • Protective mask, gloves.

Before cleaning, the air conditioner must be disconnected from the mains and the decorative cover must be removed.


The filter is the first place to start. After removing the decorative cover, you will immediately find it. The filter is a large mesh plate made of dense plastic. It can be washed repeatedly. Other types of filters installed in your air conditioner will most likely need to be replaced immediately.

cleaning the air conditioner filters

Remove the filter from the housing by snapping the latches around the perimeter. Pour warm water into the container, add detergent. Use special cleaning agents for air conditioners. Now the most important question: how to clean properly? There is no wisdom here. Rinse the filter in a container of water, remove stubborn dirt with a sponge and rinse under running water.

Put the filter on a towel and leave it to dry in the living room. Do not use a hair dryer to dry the filters!

While the filters are drying, you can also clean the other components of the indoor unit. First, vacuum the air conditioner from the inside using a nozzle with a narrow nozzle. Try to get to the most inaccessible places. And then proceed to a more detailed cleaning.

Dissolve a little detergent in warm water and use a soft cloth to apply it to the radiator and fan. Usually at this stage, there are many questions about how to wash the fan blades and not harm the air conditioner. Proceed with caution. Pour the water with the cleaner into the spray gun and apply the mixture to the blades, wait for 15-20 minutes, and then use a sponge if the cloth does not help to get rid of dirt.

Drainage cleaning

Cleaning the drainage system is a separate topic of conversation. In some models, the drainage is not located in the most convenient place, and sometimes it is difficult to clean and disinfect it. And insects often get stuck in the drainage pipes.

You can do the following. Take the unnecessary tight wire and insert it into the drain tube, then push it forward until the end of the wire comes out of the other end of the tube. So you are at home cleaning it from insects.

Also clean the tray. It has an oblong shape and is located in the wall unit, in its lower part. Be careful when removing the tray, it may contain water and mold. Clean it in the same way as the filters. But be sure to use a brush to remove even the most difficult-to-remove dirt.

Cleaning the air conditioner will be incomplete if you forget about the decorative cover. It also needs to be wiped with detergent to get rid of dust and dirt.

This is the end of the self-cleaning of the home air conditioner. If you are not ready for this amount of work, you can use the help of a specialist. But this service is usually paid.
