1. The outdoor unit of the air conditioner is "frozen" and the frost of the outdoor unit is cleaned. 2. If the heat energy is insufficient, add Freon. 3. There is too much dust in the filter screen, and the reason and solution for the air conditioner not heating after regular cleaning is the filter screen. 4. The air conditioner is damaged and strikes, and the air conditioner is repaired or replaced.
