My Lennox air conditioner air handler unit is forming condensate on the outside of the unit. How do I repair

Apple asked:
The unit is a heat pump and is about 1 year old. The air handler is mounted to the floor rafters for our second floor and hangs in our basement. The drain line is not blocked. The unit is dripping about one-half gallon per day of condensate to the ground. I normally run the air conditioning unit at 78 degrees. We do live in a humid environment.

The unit for the upstairs is operating fine with the air handler located in the attic.
The Lennox Customer Service Department will only talk to its dealers about service issues…so no luck there. The local Dealer has been out twice but unable to locate the problem.

There can be several causes. Dirty filters can cause low supply air temp and create sweating. Check you filter first. Also make sure the evap is not freezing up. Double check your drain pan for cracks.It is plastic and sometimes can get cracked during installation if the fittings are overtightened..Also check that the cabinet has all the factory insulation in place.Make sure your ductwork is sealed at the unit.Air leaks in the return duct in a humid condition can cause excessive sweating.Make sure your ductwork is properly insulated if the unit is in an unconditioned space. If that doesn’t help then please be more specific as to where exaxtly the water is leaking from,and does it drip more when the unit turns off.
