The main goal when dismantling the indoor unit of the air conditioner is not to spill freon. Before removing the indoor unit of the air conditioner, you need to stock up on the necessary tools. The main tool is hex wrenches, which should fit the diameter of the valves on the tubes. We start the equipment for cooling and as soon as the cold air flows, you need to immediately screw 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 cut off the copper pipes with large nippers (the ends will be compressed, nothing will get inside).
We 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 in case of freezing and leaking of the indoor unit of the air conditioner
Often, freezing or leaks are caused by an illiterate installation and installation of the indoor unit of the air conditioner.
The reason may not be one, but a whole complex. Before removing the indoor unit of the air conditioner for repair, it is advisable to simply clean it.
A dirty filter and fan are the most common causes of frost formation.
You can independently check whether the compressor stops when the required temperature is reached in the room.
The rest of the 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 has appeared. Most often these are problems with the evaporator.
To ensure long-term and uninterrupted operation of the equipment, entrust the installation and installation of the indoor unit of the air conditioner only to specialists from the service center.
