So my 2nd story bathroom was flooded, resulting in water pouring down into my heating vents. I turned down the furnace for now until I knew what effects the water might have, but can't find any info about it on-line. My gut instinct says that it's fine, or they would have some kind of codes on how vents have to be installed in places where water is around (bathrooms, kitchens, laundry rooms, etc.). My gut instinct, however, isn't always right. Can anyone help me out with this? Thanks!
It's hard to guess how much water got into the duct. You may have some that is laying on horizantal runs. I believe the only thing you can do is to run the furnace fan on high and shut down the humidifyer. Any water left in the duct will evaporate much quicker. Check the furnace blower area and around the electronic controls for water. If they are dry, then you are ok there.
Any water in ducts will evaporate in time.
