I have a gas hot air furnace and my question is, when my heater is on hot air comes out of the supply duct while cool air blows out of my return ducts. Is this how it works?0 -
cold air
hold a piece of paper or tissue over the return duct. it may feel like it is blowing but the paper should get sucked in. if not then i think somehow a duct is disconnected and you are pulling in cold outside air.
