There can be several reasons why an air conditioner is not cooling and windy, and here are some possible reasons and solutions::
1.The air conditioner will have a defrosting process before it starts heating. If the air conditioner is out of refrigerant, you can ask a professional to add some refrigerant. If the four-way valve is broken, you can turn off the power of the air conditioner and find a professional to come to the door for inspection and repair.
2.The air conditioner is not refrigerated and windy, which may be due to the fact that the inner filter and the condenser of the external unit are not cleaned properly. The pressure of the system is low, and it will be more difficult for the air conditioner to work in a low temperature environment.
3.It may be that the pressure of the system is low, and it will be more difficult for the air conditioner to work in a low temperature environment. The temperature can be increased appropriately, preferably at about 20 degrees, so that the air conditioner can be cooled normally.
4.It may be that the internal filter and the condenser of the external unit are not cleaned properly, the pressure of the system is low, and it will be difficult for the air conditioner to work in a low temperature environment. You can clean the inner filter and the condenser of the external unit, or add more pressure pumps to the low pressure of the system, so that the air conditioner can work normally.

10.It may be that the internal filter and the condenser of the external unit are not cleaned properly, the pressure of the system is low, and it will be difficult for the air conditioner to work in a low temperature environment. You can clean the inner filter and the condenser of the external unit, or add more pressure pumps to the low pressure of the system, so that the air conditioner can work normally.
The above are some possible causes and solutions about the air conditioner not refrigerating and windy, I hope it will help you!
