water in duct work when A/C runs
last summer when we turned on the central A/C we noticed water leaking from the flexible tubing that joined the trunk line that feed the second floor of our house (we have forced hot air so both A/C and heat run through it) - we have had this unit for about 10 years with no issues. We thought it was because the pump line was clogged and cleaned that. We replaced the 5ft piece with R6 flexible tubing and the problem happened again. This year we put up an uninsulated flexible tubing to see where the water was coming from. After running it for a few days we noticed that there was again water inside the trunk line. There is no evidence of it coming from the furnace and no visible drips/calcifacation from the trunk line. it seems to be forming in the 90 degree bend leading up to the second floor.
We do not have a problem with water on the floor but do get some condensation of the lines as the A/C is located in our unfinished basement.

Condensation problems usually occur on the outside of ducts, so I'm wondering if somehow you have a leak in the duct which allows condensation to come back inside the duct and then flow down to where you notice it.
