The main goal when dismantling the indoor unit of the air conditioner is not to spill freon. Before you remove the indoor unit of the air conditioner, you must stock up on the necessary tools. The main tool is hex wrenches, which should fit in diameter to the valves on the tubes. We start the equipment for cooling and as soon as the cold air starts, you need to immediately tighten the fitting on the tube of a smaller diameter (freon supply). The air gradually warms up, and as soon as it warms up noticeably, close the second tube (you need to wait a couple of minutes). Then turn off the device. We bite the copper tubes with large nippers (the ends are compressed, nothing gets inside).
Turn off the switch and disconnect the wires. We remove the modules from the brackets and the dismantling of the indoor unit of the air conditioner is completed.

What to do when freezing and leaking the indoor unit of the air conditioner
Freezing or leaking is often caused by illiterate installation and installation of the air conditioner indoor unit.
The reason may not be one, but the whole complex. Before removing the indoor unit for repair, it is advisable to simply clean it.
A dirty filter and fan are the most common causes of frost.
You can independently check whether the compressor stops when the required temperature is reached in the room.
Other manipulations are available only to professionals. They will test the operation of the control board, temperature sensors, the amount of refrigerant in the system and indicate why this problem appeared. Most often these are problems with the evaporator.
To ensure long and uninterrupted operation of the equipment, trust the installation and installation of the indoor unit of the air conditioner only to specialists from the service center.
