The reasons for the appearance of dirt in the climate device

Often the air conditioner works indoors constantly. As a result, the split system is largely clogged with dirt from the air. The main reasons for this effect are the following factors:

  • The device draws in untreated air, and after processing it releases fresh and clean into the room. All dirt settles in the outer and inner block. To remove it, you should know how to clean the split system.
  • Humidified air that enters the air conditioner releases condensed moisture. It is she who causes the development of harmful microorganisms, the appearance of fungus, mold and unpleasant odors in the room. An air conditioner clogged in this way can not only malfunction, but also cause a violation of the health of the occupants of the room.
  • The low height of the device is also one of the reasons for the clogging of the split system. Such placement increases the load on the air conditioning compressor. Dust from the street and exhaust gases in large quantities fall into the external unit of the device, especially if it is located on the lower floors of multi-storey buildings.

Important! The best solution to this problem would be to install an external air conditioning unit at the highest possible height.

  • In the summer, the factor that causes rapid contamination of the device is poplar fluff. If you do not remove fluff particles from the device in a timely manner, it can provoke blocking the operation of the entire system.
  • Various midges, ticks and other parasites very quickly appear and develop on the dirt accumulated in the air conditioner.
  • The lack of cleaning procedures in the block responsible for the accumulation of dirty water leads to overflow and the formation of blockages. This liquid will enter the room through the grille, and thus the air conditioner will not clean and freshen the air, but will clog it.

Important! If you’re not so confident in yourself that you can completely clean the entire system, including the outdoor unit, read about how much does a professional air conditioner cleaning cost.

Refrigerant control

It is necessary to constantly monitor not only the cleanliness of the split system, but also to control the level of refrigerant in the device, because a decrease in this substance also significantly worsens the operation of the climate device. The main refrigerant in the air conditioner is freon, which is subject to natural evaporation.

Important! About 9-10% of the substance evaporates per year.

In order to avoid serious damage, the control of the freon level must take place constantly, and the device must be filled in time.

The fact that the device does not have enough refrigerant is evidenced by several factors:

  • Establishment of a room temperature different from the set temperature

At the first appearance of such signs, it is necessary to disconnect the air conditioner from the network and fill the device with freon.

Important! In the instructions for the device, you need to clarify which particular gas station your split system supports. If the air conditioner cannot be partially charged, you should pump out all the remaining refrigerant and refill the appliance with freon.
