Installing an air conditioner is a process that can seem complicated, especially if you are doing it for the first time. It is advisable to contact professionals from air conditioning installation and maintenance companies, such as air condition services, to ensure the system is properly and safely installed. However, by following this step-by-step guide, you can successfully install your air conditioning system and enjoy the comfort of your home.

Air Conditioner Installation

Choose the right type of air conditioner

Before installing an air conditioner, choose the most suitable system for your home or office. Different air conditioners exist:

  • Window air conditioners;
  • Wall-ceiling air conditioners;
  • Wall-mounted split systems;
  • Multi-systems;
  • Mobile air conditioners;
  • Evaluate your needs and capabilities to determine which type of air conditioner is best for you.

Choose an installation location

Choose the best place to install your indoor and outdoor air conditioner units. The indoor unit should be installed so that the air is evenly distributed throughout the room, and the outdoor unit should be in a location with good ventilation and condensate drainage. Consider factors such as the availability of electricity, installation space, and obstructions such as windows and doors.

If you take care of the installation scheme beforehand, you will know what materials you will need for the installation of the air conditioner and their quantity (cables, wires, copper pipes, tape), what list of works you will need to do besides standard ones:

  • Pave chinks or lay a box;
  • Make additional holes in the walls if the units are on different sides;
  • Increase the freon amount due to the increased length of the connecting line, etc.

When starting to install an air conditioner, it is recommended to apply to competent specialists from air condition services who will provide quality installation and long-term operability of your air conditioning system.

Routing lines for connecting the equipment

Installation of the split system includes creating two mains – for freon and connecting the equipment to the electric network. The first line connects the indoor and outdoor units. On this main pipe, go:

  • Copper tubes;
  • Electrical cable;
  • Drainage hose.

The cables, pipes, and hose are laid in a box or in the grooves to make the line look aesthetically pleasing. It all depends on the interior design conditions and the owner’s wishes. The second line is intended for connecting the indoor unit to the mains. Sometimes, if the indoor unit is located near the socket, this line is not created, and the unit is simply connected with a cable with a plug.

Connecting the communications

Run the tubes and wires through the holes in the wall, then connect them to the appropriate connectors on the indoor and outdoor units. Now connect the communications between the units: copper tubing, electrical wires, and drain hose. Make sure all connections are tight and leak-free.

Starting and testing the system

Once the installation is complete and all the utilities are connected, turn on the air conditioner and check its operation. Pay attention to parameters such as temperature, air flow rate, and noise level. If the system is not working properly or there are problems, contact professionals for diagnosis and troubleshooting.


Following this step-by-step guide, you can install and set up the air conditioning system in your home or office. It is a reminder that to ensure a quality and safe air conditioning installation, it is advisable to contact professionals such as air conditioning services that provide air conditioning installation and maintenance services.
