I am having a new gas furnace (95 percent efficient) installed on Friday and am undecided on whether to have combustion air piped from outside or drawn from basement.
The contractor is willing to do both and it is my preference. Intake pipe will be neatly run next to the exhaust pipe. I will have to put some vents in the door to the mechanical room in order to meet the volume/BTU requirement if I go with inside air. Not a big deal, have already purchased the vents.
Anyone have quick thoughts on this matter?
