Furnace Vent Condensation Concerns
We had a new HVAC systems installed a little over a year ago. I was in the crawlspace this morning, and noticed that the concrete wall was damp with some efflorescence right beneath where the furnace vent enters the base of the chimney. See attached image.
I've already scheduled an HVAC tech to come out to the house tomorrow morning, but I'm wondering if I should also get a chimney inspector involved? I just want to make sure that I'm not getting a band-aid solution or incorrect solution.
I don't beleive we had this issue prior to the new furnace. I've done some research, and it seems that perhaps the higher efficiency furnace may be the culprit and that the exhaust isn't exiting the flue prior to condensing. If that is the case, what are the potential solutions? Is there an active element that can be added to the path to force the exhaust out more quickly?
