Slowly add refrigerant to the system. The pressure gauge and stop adding refrigerant when the pressure reaches the recommended level.
Close the valve on the AC recharge kit and remove the canister.
Check the pressure and that it’s within the recommended range.
Disconnect the AC recharge kit from the low-pressure port and replace the cap.

Step 7: Test the AC System

After adding refrigerant, it’s time to test the AC system. Follow these steps:

Turn on the car’s engine and set the AC to the maximum cool.
Check the air coming out of the vents. It should be cold.
If the air is not cold, or the pressure in the system is too low, the AC system may have a leak or other issue that needs repair.
