Upon arrival, I found the customers Daikin mini split not cooling properly due to a low refrigerant charge. The system was almost completely out of refrigerant. It holds a little over 2 pounds. I sent an estimate for 2 pounds. The estimate was approved. After adding 2 pounds of refrigerant the system started cooling properly . I then performed an electronic leak search. But the wind and rain was so bad outside. My leak detector was trying to hit outside in the condenser, but I will have to do a follow up and return when the weather is better so I can be positive. We will call to schedule a follow up. The customer is also interested in prices on a new mini split. Your system is cooling properly at this time. There is no guarantee to how long the refrigerant will last.
