What size sheet metal pipe should I use for my apartment building
8 unit apartment building. Each unit has 2 bedroom, kitchen and living room. I need to start putting the ductwork together. I will be buying 80,000 btu furnaces. each unit has its own furnace in the kitchen.
Some people said 6 inch pipe but some said 8 inch, i need your opinion.
