- 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.
How to recharge car ac- Conclusion:
Recharging the car’s AC system is a simple process that can be done at home or at a local repair shop. Follow the steps outlined in this article, and take the necessary safety precautions. Remember to check the pressure in the system before adding refrigerant and stop adding refrigerant when the pressure reaches the recommended level. With a properly functioning AC system, you can enjoy a comfortable ride, even in hot weather.
How to recharge car ac- FAQ
Is it okay to refuel your own car’s ac?
