Home Air Conditioning Systems: the Main Types and Their Peculiarities


Air conditioner has long ceased to be considered a luxury. Today it is a necessary thing in any house, because with the help of a properly selected air conditioning system you can maintain a good microclimate and create comfortable living conditions.

With the help of a good air conditioning system at home you can solve various tasks. In addition to cooling the air and maintaining a comfortable temperature, modern air conditioners can perform many other functions: moisturizing or dehumidifying, providing normal air exchange, cleaning the street air.

What do I need to know when choosing an air conditioning system for a private house?

In ideal circumstances, the selection of air conditioning system should be carried out at the design stage. At this stage it is possible to organize interaction of the air conditioning system with ventilation and heating systems. This is convenient and helps to reduce the cost of maintaining a comfortable microclimate in the house.

When choosing air conditioning and ventilation systems in an already built private house, a huge number of parameters are taken into account:

  • What condition the electrical wiring is in;
  • Architectural features of the house;
  • The performance of the systems;
  • The total area of the house and the number of rooms;
  • Climatic and weather conditions;
  • Matching equipment specifications to the specific room type and more.

In order for the air conditioning of a room to be really effective, it is necessary to take a responsible approach to the choice of the system. Most often in this matter can not do without the help of experts.


Split systems are probably the most popular type of air conditioning, consisting of one external and one internal unit. Such systems are chosen first of all because of their affordable price, practicality, ease of installation and maintenance, quiet operation of the air conditioner. However, split-systems have their disadvantages. The first of them is absence of fresh air inflow. The second disadvantage is the possibility to maintain the necessary temperature only in one room. That is, for each room it is necessary to install a separate split-system, which is not always convenient and rational. In addition, such a system of air conditioning in the house can spoil the facade with a large number of outdoor units.

More advanced variant are multi split-systems designed for air conditioning of the whole house. Such systems have only one outdoor unit and up to six indoor units. Thanks to this, the appearance of the building is not spoiled, and it is possible to maintain the desired temperature in different rooms.

Central air conditioning system

A central air conditioning system is a multifunctional system that is mainly installed in large-sized houses. Such systems clean, heat and cool the incoming outdoor air. After that, the purified air of the required temperature is evenly distributed to all rooms with the help of duct systems passing through all rooms.

The central air conditioner unit has large dimensions and needs regular maintenance. Earlier central air-conditioning systems were used mainly to maintain optimal microclimate in administrative buildings, airports, medical and shopping centers, sports arenas and so on. But lately they are gaining popularity among owners of private houses with the area from 100 m2.

This is due to a number of advantages of such systems:

  • Durability and reliability of installation;
  • High performance and energy efficiency;
  • There is a possibility of using a multi-zone system;
  • Multifunctionality, including CC systems can perform the function of ventilation;
  • High level of automation;
  • Can be used in any private houses, regardless of their floor and total area.

Ducted air conditioning

A ducted unit is a sub-species of a CC and is a modern home cooling system. Ducted air conditioning systems consist of a single indoor unit that is concealed under the ceiling. This unit is connected to a duct that leads to all rooms. Such systems work on the principle of recirculation: the exhaust air is taken from the room through the intake grille, passes through the internal unit, mixed with fresh street air and fed back into the room. At the same time, the desired room air temperature is set. In this way, air exchange and air conditioning are realized at the same time. Duct air conditioners can be combined with the supply and exhaust ventilation system not only by ducting, but also by control.

The main disadvantage of duct air conditioners is that it is necessary to choose a “reference” room, by which the optimal temperature will be determined. In other words, it is impossible to set an individual temperature mode in each room. The system will always be guided by one room, regardless of what the actual air temperature in other rooms will be. At the same time, it is impossible to stop air conditioning one particular room.

When choosing an air conditioning system for a private home, consider your own wishes first. When you decide what functions the air conditioner should perform, it will not be difficult to choose a suitable system.
