How to Install a Split System Air Conditioner

On hot summer days, air conditioning becomes one of the most important appliances in the home. The split system is one of the most popular types of air conditioners. It consists of two units: indoor and outdoor.

The indoor unit is installed indoors and the outdoor unit is outdoors. Below we will look at how to install a split-system air conditioner so that you don’t need ac repair or maintenance from ac services.

Step By Step Process To Install A Split AC

Prepare all the necessary tools

Before you start installing the air conditioner, you need to prepare all the necessary tools. These may include screwdrivers, pliers, hand tools, freon tubing, cable, cable conduit, bolts, and nuts.

You also need to purchase an installation kit, which usually includes all the necessary items for installation.

Determine where to install the indoor unit

Before you start installing the indoor unit, you need to determine where to install it. This can be a wall or a ceiling. It is important to make sure that the chosen location will not impede free access to the air conditioner and will not interfere with its operation.

The next step is to install the indoor unit. To do this, attach the fasteners to the wall or ceiling according to the installation instructions. After this, install the indoor unit on the fixing elements.

Install the outdoor unit

After the indoor unit is installed, the outdoor unit must be installed. To do this, you need to find a suitable place to install it. This can be on the balcony or the wall of the building.

Then it is necessary to fix the outdoor unit in the chosen place with the help of fasteners and connect it to the indoor unit with freon pipes and a cable.

Connect the air conditioner to the electric network

After installing both units, it is necessary to connect the air conditioner to the electric network. To do this, you need to connect the cable to the indoor unit and run it to the outdoor unit.

Then you need to connect the cable to the outdoor unit, which will then be connected to the socket.

Fill the system with freon

Once both units are installed and plugged in, you need to fill the system with freon. This can be done with a special hose and freon bottle. It is important to fill the system correctly, follow the instructions, and not let the freon leak.

Check the operation of the air conditioner

After the system is filled with freon, it is necessary to check the operation of the air conditioner. To do this, you need to turn it on and see if it is working properly. If everything is set up correctly, the air conditioner should run quietly and cool the air.

Additional recommendations

When installing a split-system air conditioner, you should also consider some additional recommendations:

When choosing where to install the indoor unit, make sure that the airflow is not directed toward a place that is frequented by people or animals. This can lead to undesirable effects, such as colds or other illnesses.

When installing the outdoor unit, make sure that it is installed in a stable location and will not be exposed to strong winds or other natural conditions.

All precautions, such as the use of insulating materials and avoiding damage to the cable, should be observed when connecting to the electrical grid.

The filters of the indoor unit should be cleaned regularly to ensure that the air conditioner works smoothly and avoid problems with the air exchange in the room.


Installing a split-system air conditioner is not a difficult task if you follow the instructions and recommendations. Proper installation and wiring will allow you to enjoy comfortable and cool air on hot summer days.

If you are unsure of your abilities or don’t want to take the risk, it is better to enlist the help of professional installers. This will ensure a reliable and safe air conditioner installation as well as a warranty on the work done.
