Frozen condensate overflow line
Down here in Atlanta, I have had two friends call me recently with condensing furnaces that shut off during several days of freezing weather. It seems that the overflow line from the condensate pump taking flue moisture out ran heavily during the cold weather, froze solid at the end outside, causing the pump to back up and the overflow switch turned off the air handler.
Do any of you northern climate folks have a solution for this? One of them doesn't have an interior floor drain to run it to. What's the normal method in the north?

I have a crawl space with cold joints that are inadequately sealed and ooze water. How can I seal them.
