Question about Heating & Cooling
Hi, this is a 10 ton a/c unit, more then likely has 2 stages of cooling. You say the copper suction line is wrapped with insulation already, and the problems continue? What you need to do next as the evaporator coils are in the ceiling, is to have a condensation pan made to cover the bottom of the unit to catch any moisture that drips from the suction line and evaporator coils and have a 3/4" drain that will drain into existing condensate line. You can't prevent the suction line from sweating has thee cold temperatures are reaching its dew point and will always drip. The line should be wrapped with a black cork type insulation that has a sticky back that is made for this suction line. All you can do is have a sheet metal pan made to put under this unit to catch the moisture and let it drain or evaporate if its not real bad. I have seen this many times with units that are in the ceiling, which will destroy the tiles. Keep in mind that the suction line will reach temperatures of 40*F and will drip condensation when it is cooling so they should have put a pan under this unit when it was installed. This will solve the problem, and that's about all that you can do. Please don't forget to rate me as I know you will be kind. I wish I had other ways to solve this, but this is the only way, and the way it should have been done to begin with.
