Hardwood floor buckling from HVAC duct underneath
Duct is about 8X5 rigid, and its insulated, its pretty much almost up
against the floor. Thers no way to lower the duct because the floor
joists are 2X8's, so the duct would sit lower than the ceiling. I use
forced hot air, no humidifier in the house , basement is dry, whole
house is dry, so I don't think it's humidity or moisture related.
