For this cooling tune-up I inspected the air handler and condenser. While inspecting the air handler I noticed a small leak from the Schrader core of the suction line connecting to the EVAP coil. I leak detected and was getting positive Hits on that Schrader indicating there was in fact a leak coming from that spot. When I gauged up the saturation temp was 33° and superheat was 34, I charged the unit to 14° super heat which is what my chart was telling me based off the wet bulb and ambient outdoor temperature. When I left I set the thermostat to 72° and the air coming out was 51°, and 69 in the house giving me a 18 degree Delta.
