When recharging AC is in the red?

If the AC refrigerant level indicator is in the red zone, it means that the air conditioning system is low on refrigerant. Refrigerant is the fluid that circulates through the air conditioning system and absorbs heat from the air. When the refrigerant level is low, the air conditioner will not be able to cool the air effectively.

The following are some of the reasons why the refrigerant level may be low:

- A leak in the air conditioning system

- A faulty compressor

- A malfunctioning expansion valve

- Incorrect charging of the air conditioning system

If the AC refrigerant level indicator is in the red, it is important to have the air conditioning system inspected and repaired by a qualified technician. Driving with a low refrigerant level can damage the air conditioning compressor and other components of the air conditioning system.
