Upon arrival system was not operational. System is 21 years old and has had a couple repairs done to it. Testing found the capacitor had failed. Inspected fuses and they are were hot to the touch. Installed new capacitor and tested motor amps. They were almost at max and the compressor is in danger of failing. Went into attic and inspected indoor unit. System is not on a proper platform and is just resting on 2x4s. There is no emergency drain pan installed and the condensate lines are tied together. System is a 5 ton unit running on 3 tons of ducting. Extremely inefficient. Made repair options and talked about replacement. Clients went forward with repairs. Clients are aware of the condition of the unit and that this isnâ€™t a long term repair. This repair is to buy more time before either replacing the compressor or system. Clients moved forward with maintenance program. Unit is operational upon departure.
