Floor-ceiling air conditioners are irreplaceable in cases where there is a lack of power of a wall split system, and the installation of cassette air conditioners is impossible due to the lack of a suspended ceiling. Floor-ceiling air conditioners are intended for installation in relatively small rooms. Such types of air conditioners have a rectangular shape up to 20-25 cm thick and resemble a heating radiator. Many people think that air conditioner maintenance is only cleaning the filters, but this is not true. Poor or complete service can lead to a gradual deterioration in the operation of the air conditioner, and subsequently to various breakdowns, up to and including compressor failure, which entails repair. Service is a sequence of various measures to maintain the operating parameters of the air conditioner at a level. Only a company with the appropriate certificates and experience can provide services for the maintenance of floor-ceiling air conditioners. The Server-Service company is just such an organization.
