How to Add Car Refrigerant?

[EliasLynn]

Car refrigerant can be added by following these steps: 1. Prepare the necessary tools and materials, including a car refrigerant recovery and charging machine and refrigerant; 2. Connect the hoses of the car refrigerant recovery and charging machine to the high and low-pressure pipes of the car's air conditioning system; 3. Perform a vacuum process on the car's air conditioning system; 4. Set the charging capacity, time, and type on the refrigerant recovery and charging machine; 5. The refrigerant recovery and charging machine will then automatically begin adding refrigerant. Methods to determine if a car needs refrigerant: 1. If the air conditioning reaches the set temperature quickly after being turned on for a while, it indicates normal operation; otherwise, refrigerant needs to be added; 2. Use a thermometer to measure the temperature difference between the air inlet and outlet of the indoor unit—if the difference is below approximately 8 degrees Celsius, refrigerant needs to be added.
