I have an HE gas Lennox 92AF1UH that seems to be leaking from the exhaust moisture collector (not the technical term). When we opened it up initially the filter was completely waterlogged & moldy. We blew out the hoses and dried everything out, but there is still moisture accumulating after its run. The unit is five years old. Any thoughts?


While water is difficult to track the source/problem via the internet, I can say that a 5-year-old Lennox may well still have a parts warranty so if you get a tech you might only have to pay labor. Your heat exchanger definitely has a warranty if it's the issue.
