- Solution: Replenish the refrigerant and eliminate leaks in the system.
2. Four-way valve failure
- The function of the four-way valve is to switch the flow direction of the refrigerant to achieve air conditioning cooling or heating. Convert.
- When the four-way valve fails, the air conditioner cannot switch to heating mode.
- Solution: Replace the four-way valve.

- In a low temperature environment, the evaporator of the outdoor unit may frost.
- Frost will hinder the heat dissipation of the outdoor unit and affect the heating effect.
- Solution: Defrost regularly or replace antifreeze.
4. Filter clogged
- The air conditioning filter can filter dust and impurities in the air.
- When the filter is clogged, it will affect the air inlet volume of the air conditioner and reduce the heating efficiency.
- Solution: Clean or replace the filter regularly.
