I think I'll have to break down and hire an HVAC company to setup a zoning system. Our 2nd floor and 1st floor are never the same temp. Plus, with fully sealed up rooms in the basement I think it is wise to bite the bullet. I know these questions will be answered by a HVAC contractor, but of course I want to tap into the AVS wisdom.
I checked out our current furnace, the
Bryant 310AAV066135AAJA. There are two, three, four, and eight zone systems identified in the specs as compatible. At a minimum I'd like to go with three zones (one per floor). However, I'd prefer to have eight unless it doubles the cost.
Specs:
Input Btuh - 132,000
Output Btuh - 107,000
AFUE - 80.0
Certified Temperature Rise Range 40-70
Certified External Static Pressure (Heat/Cool) - 0.20/0.50
Airflow CFM (Heating/Cooling) - 1850/2110
Blower Direct-Drive Motor HP (PSC) - 3/4
My eight zone example...2nd floor
Zone 1 - kids bedrooms, bathroom
Zone 2 - bonus room, guest bedroom
Zone 3 - master/bath/closet
1st floor
Zone 4 - kitchen/nook, family room, dining room, living room, bathroom, hall
Zone 5 - office
Basement
Zone 6 - theater
Zone 7 - studio/control room
Zone 8 - hall, bathroom
Questions:
1) Does it look like my furnace will be able handle an additional ~1,000 sqft on top of the current ~3100 sqft?
2) Is my desire for eight zones a little bit ridiculous? Would a zone for each floor be acceptable for most people?
