Even today, many people do not know whether it is possible to turn on the air conditioner for heating in winter. It is believed that air conditioning is needed in the heat, and the rest of the time it is idle. It is also believed that turning on the device in the winter can lead to a breakdown of the unit. This is due to the fact that older models could not work at low temperatures.
Read on if you are interested in whether it is possible to turn on the air conditioner in winter, to what temperature the air conditioner can be turned on and why the heating of the air conditioner does not work.
Is it possible to turn on the split system in winter. Let's answer right away - yes, you can.
There are two types of air conditioners: non-inverter and inverter.
The first can work up to -7 degrees Celsius, they are sharpened for cooling, so working at lower temperatures will lead to device failure.
The second type of air conditioners is gaining popularity. They are designed to operate at relatively low temperatures with high humidity. Inverter models are best for working in the winter. They are able to heat the air at a temperature of -20/+15 degrees, and cool in the range of +18/+45.
As for monoblock air conditioners, it is not recommended to run them in severe frost. If the air temperature is below -5 (or 0 degrees, but high humidity) degrees Celsius, then the equipment may fail. The operating range of the air conditioner in heating mode is -5 / +25 degrees Celsius, and in cooling mode - from +18 to +25.
It is worth noting the latest models of Mitsubishi air conditioners - they are equipped with inverter compressors and fans. This means that such devices can operate at temperatures down to -35 degrees Celsius.
Budget models can withstand a fifteen-degree frost.
Cooling in winter. Why cool a room in winter? Few of the users thought that they would use the air conditioner in cooling mode in winter. There are a number of sanitary and hygienic standards, including cooling with air conditioning in winter. Most often, this is used in commercial and medical institutions - MRI rooms, services, stations with television and radio equipment.
There is an opinion that in order to work in winter, the air conditioner must be equipped with a winter kit. This is false. Winter kits are something like a jacket for air conditioning. They are equipped with older models so that they can withstand lower temperatures. But modern systems already operate at such temperatures.
The heating mode of the air conditioner does not work. Most split systems are equipped with an automatic defrost system. Temperature sensors are installed on the heat exchanger: if it is covered with ice or the temperature is too low, then a signal is given to the control system. It includes defrosting of the outdoor unit. At such moments, it may seem that the air conditioner does not work or does not work correctly, but everything is in order. The principle of operation is as follows: the device switches to cooling mode and turns off the fan, cold air does not enter the room, but the components, in particular the heat exchanger, heat up and the ice melts. After the normal temperature is restored, the air conditioner continues to operate normally.
If a sufficiently long time has passed, and the heating has not started, then a breakdown may have occurred. Self-repair can be dangerous for you and damage the equipment. It is recommended to call a professional.
Reasons why the heating mode does not work. Their list includes:

The previously considered auto-defrost of the external unit. Give the air conditioner 10-20 minutes and it will work normally again.
Clogged filtration system or heat exchanger. It is necessary to disassemble the indoor unit and wash the filters. Rinse them only under cold water, because of the hot they are deformed. If the heat exchanger is clogged, you need to disassemble the outdoor unit and clean it. If this is not done, the compressor will break.
The device is operating at an unacceptable temperature. Each model has limitations on use, we described them at the beginning. To find out exactly at what temperatures the unit can operate, refer to the instructions.
Not enough freon. It could be a leak, or it just evaporated. In any case, we advise you to call a specialist to refuel the air conditioner with freon.
Breakage of components. The compressor/fan, temperature sensors, or valve may be broken. If you do not have experience in repairing air conditioners, it is recommended to contact the service or call the master.
