The air conditioner does not work for heating, and it is cold and damp outside - this is a real problem for residents. Most often, they use the opportunity to warm the air during the off-season, when the cold has already arrived, and central heating is still not working. In terms of efficiency, heating with an air conditioner significantly exceeds all existing heat sources, because the air is blown out by powerful fans, therefore it cannot be said that the air conditioner does not heat. Heating is quick and cost-effective.
Air conditioning does not heat: severe frost
When the air conditioner does not warm in frosty weather, the problem is not in the equipment. He simply has nowhere to get a lot of heat from. This is due to the principle of the compressor and does not indicate a breakdown of the air conditioner. No more than 3 degrees will be added to the air temperature in the room. The most efficient heating is provided at a temperature from 0 to +5 degrees of atmospheric air.
Most models are designed to work for heating up to -10 degrees, some function at -20.
No heat: valve broken
If the air conditioner does not work for heat, but it blows from the indoor unit and the compressor works, the cause may be a breakdown of the four-way valve. This valve is very important, it is responsible for the transition from the winter mode to the summer mode and vice versa.
When the air conditioner does not work for heat, the compressor does not start when power is supplied, but an air stream blows from the internal module, probably the problem is in the compressor. It must be repaired or replaced.
The air conditioner does not heat: the defrost mode is frozen
When the air conditioner does not work for heating, but the cooling mode is operating normally, blowing from the indoor unit, the reason may be hiding in the absence of the defrost option or its violation.
Do not hurry!
Sometimes in frosty weather, the air conditioner does not work for heating when the power is turned on. The indication indicates that the system is operating normally, the fan does not start - this may mean that the indoor unit is warming up. It takes about 15 minutes to raise the temperature. In addition, the device needs time to tune in to work in the new mode. The secret is that the refrigerant flows in the opposite direction when heated. The system may not regulate the pressure well, so the air conditioner does not work for heat. No need to turn off equipment or do anything. Just wait. In some cases, an error code may even appear on the display. Also, do not rush. Even the red indicator on the board does not indicate problems.
