To add refrigerant to your home AC system, you should first turn off the system and locate the service valves on the unit. Then, connect a refrigerant charging hose to the low-pressure service valve. Slowly open the valve on the refrigerant canister and allow the refrigerant to flow into the system. Monitor the pressure gauge to ensure you do not overfill the system. Once the correct amount of refrigerant has been added, close the valve on the canister and disconnect the hose. Restart your AC system and check for proper cooling.
