How to clean the external unit of the air conditioner?

The split system consists of two major components-the outdoor and indoor units connected to each other. Many people mistakenly believe that for the proper operation of the entire air conditioning system, it is enough to clean only the indoor unit, but this is not the case. The outdoor unit also needs regular maintenance. In this article, we will tell you in detail how to clean the air conditioner, or rather its external unit.

How often you should clean up? There is no clear indication, as the frequency of cleaning is affected by many factors. In our experience, the outdoor unit needs to be cleaned at least once a year, before the start of the summer season. And even better, if you clean it after the end of the season.

Please note! Often, the external unit of the air conditioner is installed on the facade of the building at a high height from the ground. Be careful when cleaning the block. We recommend that you use the help of a specialist at all and do not risk your health.

Self-cleaning of the outdoor unit

Before cleaning, it is important to understand what components the outdoor unit consists of and what you will have to deal with:

  • Fan. It is easy to notice when removing the protective panel, since it takes up most of the space;

  • The capacitor. It is made of thin copper tubes, often located along one of the internal walls of the unit;

  • Compressor. It can be located in different places depending on the model of the air conditioner. It looks like a small barrel-shaped device;

  • Control board. Located on one of the internal walls of the unit, it is present only in inverter air conditioners;

  • Operation mode change valve. It is only present in devices with a built-in air heating function;

  • Filter. It is installed next to the compressor, designed for cleaning from dirt.

We remind you that self-cleaning of the outdoor unit can be dangerous for your health and life. In addition, after inept disassembly and maintenance, the split system may not work properly. Entrust this work to professionals!

Cleaning
