Homeowner had us out today because the system is not cooling, and he believes that the system has a leak. Upon arrival, homeowner greeted us with his own personal technician that he had known for years. The technician informed us that he’s been here multiple times and cannot find the leak. However, every time he adds refrigerant, the system leaks out. We were able to perform a quick leak search and only got small hits around the service valves of the liquid and suction line. We were not able to 100% pinpoint exactly where the leak was coming from. Within a 15 to 20 minute span we lost 0.9 psi. Recommended homeowner to look at options of replacement due to the age and condition of the system. Homeowner will contact technician or office to schedule quote at a later date.
