Central Air: Attic Ductwork Layout for Single Zone.
My other thread was: Central Air Questions for Old Home.
I am going Single Zone with unit placed in attic.
What is the best way to run the ductwork from within the attic? I’ve heard several ways. One said ductwork around perimeter of attic then tap off that for different rooms. Another said a strait branch with shoots for different rooms off that. Are those the same?
I’d like to keep some storage in the attic if I can.
I asked if they can run from the blower outside, whatever they normally up the side of the house, through the house instead. Is this okay? I’m also asking that they put registers in the walls from closets rather than the ceiling, if possible. This all makes my head dizzy. I don't want to lose the character of the home.
I just don’t want to say to myself…I should have done it this way instead.
BTW – I’m going 16 SEER Rheem
unconditioned attic space with HVAC in NJ
Wow a lot of information here, I have a somewhat similar situation... Thanks to the original poster and all the contributions.
Here is my situation;
I have a gas furnace (~80%) forced hot air and AC in the attic. It is an unconditioned space and in New Jersey (zip 08534). Also I have ridge and soffit vents. The ductwork is all insulated - main branch is ductboard and the individual supplies are round flexible ductwork.
Correct me if I'm wrong, but It appears from what I read I should seal off the attic or at least build a room around the furnace - correct? My next question would be where would the combustion air come from? (the furnace is not a direct vent.) Any leads on contractors who specialize in this type of work on central NJ? or DIY?
