We are thinking of buying this 100 yera odl house. The 2nd floor has 4 bedrooms but none of them have a heat register. The furnace was replaced in 2002 with a hi eff F/A. Someone told us that there is enough heat coming up the stairs to keep the 2nd floor warm I don't think so but my husband does. Sorry there is 1 register on 2nd floor but it is the hallway and is about a foot square. Running ducts upstairs would be very pricey. Is the person correct It is a ig stairway with a hallway.
Any thoughts? Who is right??
