Showed up because the system was sweating opened up air handler. All the insulation is soaked static pressure was high. Homeowner did want maintenance done because he installed the system about a year ago so I did a routine maintenance on the system washed condenser cleaned out drain line checked running amps on compressor check the run capacitor check the fan. Everything is working to manufacturer specs. I advised the homeowner of that. The big thing is their ductwork is undersized for that system. Homeowner had a 4 ton before upstairs gets really hot. I did advise them to solve the issue we would need to replace the ductwork. Homeowner is not happy due to the fact, they said they feel like they were ripped off would like a manager to reach out to them and explain everything again to them and go over their options. I advise them on replacing of the ductwork. Also, what a membership would cost. Homeowner would like for someone to reach out to them most likely a manager.
