Adding zone for forced air
My wife and I recently built a cape cod style home with the upstairs unfinished. I plan to finish the upstairs soon. My biggest concern is getting hvac zoned correctly. I have the shoot to get the hvac upstairs I'm just not sure if I can zone the upstairs separately or if I need a separate furnace for upstairs. Would anyone know the proper and most efficient way to do this. The downstairs is 1500 sq/ft. The upstairs will be another 1000 sq/ft. I would appreciate any help. Thanks
You could start here. http://www.energystar.gov/index.cfm?fuseaction=find_a_product.showProductGro up&pgw_code=EP#buying
And I just finished with a class on air/ heat pumps for up north here, I am impressed with these numbers they are getting for heat pumps.
The Quaternity is impressive, but only if you fix the actual home leakage issues first.
You could rent some room heaters to get an idea of how many upstairs BTUH you need to maintain X degrees F indoors while the nighttime temp is Y F.
Real numbers make contractors/suppliers sit up and pay attention. It enhances your credibility.
