    AC taking to long to cool house.
    I have a 3 ton r-22 system with straight air the cuction pressure is about65 and the discharge pressure is about 260. I have my t-stat set for 80 degrees Fahrenheit and the unit is putting out of various vent between 67 and 75 degrees. When feeling the suction line inside or hot it is nice and cool and is sweating.. I know I live in Northwest Florida and the outside temp is around 98 degrees, but why is my unit taking so long to cool. This problem just started the other day after I charged the unit. This unit is ten years old and I keep it in excellent shape.

    You have 13 degrees TD and it could be better at 15 to 18. Time to call a local professional and charge the system correctly.
