    dirty indoor coil?

    pls help

    In my opinion you've left out quite a bit of important information. Whats you indoor metering device (this determines the method for verifying correct refrigerant charge)? Once you've determined method for checking charge, what is the required superheat or subcooling. What are you indoor and outdoor temps (wetbulb and drybulb)? The past few days where I am its been very cool for august (79 degrees high temp) and very dry. I've had 53 degree suction lines that aren't sweating simply because with the low temp and humidity they suction lines are above the dew point.
