Hi Folks.. I have a question. Its been a very wet and humid late June and early July here in central NC. I noticed that the 'stand up' crawl space was quite wet and found that the water was coming from the sheet metal supply plenums and the flex ducts. They were all sweating bullets. The system is a Carrier 48XT Infinity dual fuel with 2 speed compressor so its running quite a bit dehumidifying. I tried drying the ducts off and running a fan in the crawl space which made little difference. I then discovered that the condensate drain was plugged. Could the plugged drain explain the sweating issue? Could the excess water be getting picked up by the fan and blown thru the supply ducts? Condensate did seem to be exiting the system around the base of the unit. The drain is now fixed and Ill be watching what happens under the house.
