Why Older Air Conditioners Keep Losing Refrigerant

In this video, I investigate a refrigerant leak on an older air conditioning system that had gradually lost its charge over time. After diagnosing the fault, I found the leak was coming from a common failure point on ageing systems, the service valves. Rather than replacing the entire outdoor unit, I cut out the leaking valves and soldered in copper, providing a reliable long-term repair. I’ll take you through the fault-finding process, the repair, pressure testing, evacuation, and recommissioning of the system. If you’ve got an older air conditioner that’s losing refrigerant, this is a fault worth checking before assuming the unit needs to be replaced. 📍 Sydney, Australia 🔧 Refrigeration & Air Conditioning Service & Installations 📹 New HVAC videos every week If you enjoy the video, please like, subscribe, and leave a comment with your thoughts or questions. #HVAC #AirConditioning #Refrigeration #Daikin #RefrigerantLeak #AirConditionerRepair #HVACTechnician #ServiceValve #MARACServices
