General information

Multi-split systems with 5 air-conditioning units are designed for cooling, heating and cleaning the air in five rooms. The air conditioners can be operated simultaneously, and the temperature can be adjusted separately in each of the rooms.

This air conditioning system consists of one outdoor unit, which is mounted on the facade or roof of your house, and five indoor units. Indoor units are often referred to simply as air conditioners. They can be wall mounted and channel.

Wall units are more familiar and easier to install. Channel and cassette versions look more aesthetically pleasing and fit better into the interior, but you need to design the location for them in advance.

Depending on the capacity, one indoor unit can cool or heat a room with an area of 10 to 100 square meters. But keep in mind that the more powerful the air conditioning system, the more expensive it is.

It is also important to carry out regular maintenance (at least twice a year), which will cost at least 10 thousand rubles;

  • High price. A split system consisting of one outdoor unit and five indoor units will cost 150 thousand rubles or more. It all depends on the power. However, such an air conditioner will never be cheap either when purchased or used;
