Upon my arrival in La Grange, I found that the voltage enhancement system was faulted. Spoke with the customer about their different options for repair and they chose to go with HN13D. Installed new voltage enhancement system, voltage distribution system, performance enhancement system, redid wire terminals, washed the outdoor condenser and tested the system. Found everything operating properly at this time. Spoke with the customer about our maintenance program and they weren’t interested at this time.
