Why is Recharging Your Split AC System Important?
An air conditioning system only works correctly if there is sufficient refrigerant. If refrigerant is low, the system won’t cool properly and can even be damaged. Regular checking and recharging are therefore essential for the lifespan and performance of your air conditioning system.
What Do You Need for Recharging?
Before you start recharging, you should make sure you have all the necessary materials and tools ready. This includes:
- Refrigerant bottle for your AC model
- Manifold gauge with charging hose
- Adapter for your AC model
- Safety glasses and gloves
When buying refrigerant, make sure it is suitable for your specific AC system model. You can usually find information about this in your AC system’s owner’s manual.

- Preparation: Make sure your AC system is turned off. Put on safety glasses and gloves.
- Connect the Gauge: Connect the manifold gauge to the refrigerant bottle and then attach the charging hose to the appropriate port on your AC system.
- Recharge the System: Open the valve on the refrigerant bottle and slowly allow the refrigerant to flow into the system. Monitor the pressure using the manifold gauge.
- Pressure Check: The correct pressure for your AC system depends on the model and the outside temperature. You can usually find information about this in your AC system’s owner’s manual or on the nameplate.
- Completion: Once the correct pressure is reached, close the valve on the refrigerant bottle. Then carefully detach the charging hose from the AC system.
Common Mistakes When Recharging an AC System
- Using the wrong refrigerant
- Incorrect pressure during recharging
- Not detecting leaks in the system
These mistakes can lead to damage to your AC system. Therefore, it is advisable to inform yourself thoroughly before recharging or to have the work performed by a professional.
When Should You Have Your AC System Serviced?
It’s advisable to have your AC system regularly serviced by a professional. This ensures that it always functions properly and provides full performance. Maintenance is recommended every 1-2 years or as needed, for example, if there are unusual noises or a drop in performance.
