I cycled and monitored the system for proper pressures and temperatures. It’s overcast and about to rain. It’s not the best time to check the pressures, but I measured 56 degree supply temperature at this time. I recommend coming back during the early afternoon to recheck the pressures. Customer informed me the evaporator coil was replaced last year. The duct system is not in the best shape and lose of efficiency. Customer would like a quote for the duct system replacement.
