Here’s a little secret for those of you who may be looking for a home and are energy conscious. Newer, high efficiency furnaces do not have an exhaust pipe that rises vertically (up through the roof of the house). The exhaust is actually sent out usually through a PVC pipe at an angle towards a side of the house. It may rise up from there, but it never goes straight up from the furnace like older, inefficient units.
