How do you recharge the air conditioning on a VanHool Coach?

To recharge the air conditioning on a VanHool Coach, first, locate the low-pressure service port, typically found on the A/C line. Connect a refrigerant gauge set to the port and check the system's pressure. If it's low, add the appropriate refrigerant, usually R-134a or R-1234yf, while monitoring the pressure until it reaches the manufacturer's specifications. Always ensure to wear safety gear and follow proper procedures to avoid overcharging the system.
