Arrive at the customer's house He was upset because less than a month ago, he said that a technician had come to do an Ac tune up and told him that everything was fine, and I charge him for making an acid wash condenser outdoor unit. Within a few days, the customer turned on his unit and the unit no longer cooled down. He scheduled a schedule to see what was going on, my diagnosis is that his minis split system has a leak. It is necessary to do a leak test with nitrogen and perform an evacuate and recharge afterwards. The customer says that a year ago he paid $3,000 for this problem and it is not fair that he still has it and has to pay for it again. He is very angry. Fix 2 flaps that were loose and add freon. The client was happy with the work. He wants to talk to the office in case he has this problem again, don't pay for a nitrogen leak test and evacuate
