Answer:
Removing a mini split system without losing freon involves safely recovering the refrigerant into the system’s outdoor unit or a recovery cylinder. In our experience, the process starts with connecting a manifold gauge set to the service ports on the outdoor condenser unit. Set the system to cooling mode, then slowly close the liquid line valve to direct refrigerant into the condenser. Monitor the pressure gauge and, when the suction line pressure drops to near zero, quickly close the suction line valve to trap the freon. Turn off the system, and you’re ready to disconnect the components without releasing refrigerant.

Why This Process is Important
In our opinion, safely containing refrigerant during removal is essential to comply with environmental regulations and protect the refrigerant for reuse. Proper handling prevents damage to the system and reduces costs associated with refrigerant replacement.
Step-by-Step Guide:
- Prepare the Equipment:
- Gather a manifold gauge set, wrenches, and any additional tools specified by the manufacturer.
- Set the System to Cooling Mode:
- Cooling mode ensures the refrigerant is circulating and can be directed into the outdoor unit.
- Connect the Manifold Gauges:
- Attach the hoses to the service ports on the outdoor condenser unit.
- Close the Liquid Line Valve:
- Slowly close the valve to restrict refrigerant flow to the indoor unit. This step begins moving the refrigerant to the outdoor condenser.
- Monitor the Suction Line Pressure:
- Observe the manifold gauge. When the suction line pressure approaches zero, quickly close the suction line valve.
- Turn Off the System:
- Once both valves are closed, power down the system to complete the refrigerant containment process.
- Disconnect Components:
- With the refrigerant safely contained, proceed to disconnect the system’s electrical and refrigerant lines.
Tips for Safe Removal:
- Always follow the manufacturer’s instructions for handling refrigerant and disconnecting components.
- Use proper safety equipment, including gloves and goggles, to avoid exposure to refrigerant.
- Check local regulations for refrigerant handling and disposal requirements.
By following these steps, you can safely remove a mini split system without losing freon, ensuring compliance with environmental standards and preserving the system for future use.
