Upon arrival the AC was not working at all. The thermostat would not go down below the temp in the house so I couldn’t call for cool. I went and jumpered the system on from the control board and then checked refrigerant levels and found the system was empty. I added 300psi of nitrogen to try and locate the leak. I was unable to find it. The added 1 lbs of refrigerant and the did a leak search with my refrigerant sniffer and I found the leak in the bottom left side of the indoor coil. Nick presented option to repair vs. replace for the customer. Customer then stated he was going to move out and let his contractor fix the problems. I only charged for the trip and diagnostic fee of $120. Put the system all back together before leaving. They can still use the heat but no AC. Customer knows the AC is not fixed.
