I have a BRAND NEW LENNOX split system. It's hot here right now and the new system is still working properly as in it is still cranking out ice cold air and keeping my house at the temp that I set it at but both of the ducts that feed the house with the cool air are sweating profusely and dripping all over the floor.
Obviously I will be calling the Lennox dealer who installed the unit but I would love for you to give me a bit of education so that when they come out, they don't try to blow smoke up my butt and tell me that this is normal. I know that it is not because with the system that I had for the last twenty years, those same supply feeds never even got moist, let alone so soaking wet that they are dripping all over the floor.
The only thing that I've read so far is the possibility of a clogged line on the condensation pump. I can't imagine that in only one months time, that there could be enough algae to be clogging anything.
