I have a ducane 90% furnace...My dad and his HVAC buddy installed it for me about 7 years ago. Question I have is that I was looking over it the other day and it has two 3" pvc pipes running out of it. I know the is for the exhaust and the other is for ???(fresh air). It has plenty of returns...
I have a home that is 900 sq/ft and it currently has an attic furnace. I am looking to either replace it or go with electric baseboard heat. Just wondering if anyone could help me decide....attic is nonconditioned.
