Our home is on a concrete slab, and we live at sea level. We have forced air heat with ducts under the slab. A couple of times each winter, we hear water gurgling when the heating system is on (through 3 vents near the back of the house). Is there any other way to fix this problem other than tearing up the flooring and slab to repair the ducting.
Answer:
About the only way is to tear up the floor and it would be a good idea to do this as soon as you can because that water is sending various mould spores into the house and you don't really want that.
