Refueling of air conditioners: split, mobile, household

Any air conditioner running on freon requires periodic refueling. For a properly installed split air conditioner, refueling is required approximately once every 24 months. Monoblock mobile air conditioners charge even less often. Read more about the features of refueling air conditioners of various types.

Refueling split systems

Filling domestic air conditioners with freon is one of the most popular services of service centers.

When refueling is required:

  • after compressor repair;
  • after replacing the 4-way valve;
  • after repair of the filling port;
  • after repair of the condenser or evaporator;
  • after replacing part of the cold track.

If the air conditioner operates on multi-component freon, it will not work to refuel.

The components of this freon have various physical qualities and volatilize unevenly. It is necessary to carry out a complete drain and fill in new refrigerant.

Filling of household air conditioners with freon is carried out by the following methods:

  • by weight;
  • by pressure;
  • by the method of hypothermia;
  • with visual control through the control window.

Any of the above methods of refueling household air conditioners requires certain skills and knowledge. It will also require special equipment, which not everyone can use. The procedure takes about 30 minutes. For refueling, the home air conditioner is not removed.

If the refrigerant leak is large, a diagnosis is made and leak points are identified. An excess of refrigerant and high pressure in the route badly affect the operation of the equipment. Therefore, you should not try to refuel your home air conditioner yourself.

Refueling mobile and window air conditioners

Mobile and window air conditioners are monoblocks. Their freon pipeline is filled in the factory and is absolutely tight. The question of refueling a mobile air conditioner may arise after many years of operation or when the pipes are damaged, which happens very rarely.

If the split air conditioner is charged at the place of its installation, then window and mobile air conditioners are charged with refrigerant only in service centers. Most manufacturers do not solder filling ports at all. Therefore, if there is no port, you won’t do anything at home with air conditioning. Solder nipples in service workshops.

To refuel a domestic air conditioner of a monoblock, it will be necessary to almost completely disassemble its case, which threatens to break some parts.
