Upon arrival spoke with customer. He explained no issues at this time. We started with upstairs system. Turned stat on and went into attic. Customer is still aware of drain needing a trap with a safety, disconnect to shut main power off and the heat strips in backwards. Customer explained he still plans to do it on his own, I explained we could get it done today but he is not concerned. Unit is level. Duct is all tight. Wires are tight and heat strips are working properly. Drain seems to be clear. Coil showing no signs of leaks at this time. Indoor is working properly. Went outside, coil is clean. Contacter and capacitor checked within range. Fan and compressor amped within specs. Refrigerant levels checked within specs. Disconnect wires are tight, system has no surge protectors but main panel has one so customer is not worried about them at this time. Basement system. Turned stat on. Filter is clean. Went to indoor unit. Coil is clean no leaks. Blower is clean. Wires all tight. St
