Another frequent breakdown of equipment is a refrigerant leak. As a result, the air conditioner ceases to function fully or only part of the functions is not produced. The leak, as a rule, occurs due to the fault of the persons who carried out the installation of equipment. It is with this that the requirement to entrust the installation and installation of air conditioners is connected only to professionals. Poor installation can also lead to the formation of ice traffic jams due to the presence of water and air in the contour of the unit.
