Upon arrival looked at stat and all readings where within a degree of stat set point. Went threw and made sure dampers where working. Made sure wires where tight. Blower and coil are clear. Drain line is clean. All duct is attached. Went outside, wires are tight. Contacter checked out ok, capacitor is within spec. Fan amped at .57amps compressor amped at 5.65amps. Refrigerant levels where 116/325. 10° subcool. I have a 18° split from return to supply. System is working within the limits. Explained customer system was working well, I recommend some window shades, only windows upstairs have thin covers over them. System is working well at this time. This is not a call back
