Even with a perfect installation of the air conditioner, a certain amount of refrigerant evaporates from the line. You will need to replenish to the normal volume. The fact that freon is not enough is indicated by weak air cooling. Many owners fill the air conditioner with their own hands.

Next, it is necessary to check the tightness of the pipeline in order to identify the places of leakage. For this, the system is filled with an indicator, pressure is built up. In the rays of the ultraviolet lamp, the indicator glows in the places of leaks.
Now evacuation is carried out - removal of air and possible moisture from the system. An important point is calculating the required amount of freon.
Ways to refuel the air conditioner with your own hands
For those who want to try to fill the air conditioner themselves, the video will be a very good helper.
There are several ways to self-fill the air conditioner:
- by pressure;
- by weight;
- with a sight glass.
By pressure
Before you start filling the air conditioner yourself by pressure, you should read the instructions.
Here the manufacturer gives recommendations on the operating pressure of the system. You need to stock up on a gauge manifold. Through it, a freon cylinder is connected to the air conditioner. The refrigerant is supplied in small doses. After starting each of them, it is necessary to check the pressure on the pressure gauge. When the pressure coincides with the pressure recommended in the instructions, filling the air conditioner with your own hands is finished.
By mass
Those who do not know how to fill the air conditioner with freon themselves should turn to this method. Before refueling, the refrigerant is drained and the line is evacuated. When we fill the air conditioner ourselves, it is important to follow all the technology exactly.
The freon bottle is weighed on a scale (special) and refueled into the air conditioner as much as needed. When it is known exactly how much freon is needed, a filling cylinder is used. First, freon is pumped into the cylinder, and from it into the air conditioning system. Watch the video on how to fill the air conditioner yourself on our website.
Controlled through the sight glass
Before filling the air conditioner with freon yourself, you must carefully consider the state of the refrigerant through the glass. If it contains bubbles, refueling is necessary. Freon should be poured until the bubbles disappear.
