At what temperature does the outdoor air conditioner not start in winter?

Generally, the air conditioner will not start at MINUS 5- 10 degrees.

In winter, when the ambient temperature is very low, the outdoor air conditioner can be started, but the heating effect below minus 5 degrees will be poor, and even heating cannot be achieved, and it consumes a lot of electricity. Therefore, the ambient temperature in northern China is very low in winter, so it is suggested to adopt other heating methods.
