Hi, I'm in the process of remodeling my basement and as such have completely redone the ducting of my forced hot air furnace in the bottom floor. I am looking for three recommendations to upgrade the system to a "zoned" configuration. A little bit about what I have: two stories on top of a full basement. All of my ducting is open in the basement and I can get to the runs going to the 1st and 2nd floor. My plan is to put in 4 zones: 1st floor, 2nd floor, Basement playroom, Basement family room. There is one thermostat on the 1st floor and can put another on the 2nd floor plus the two in the basement. Additionally, I plan on having an unrestricted zone (1st floor living room, kitchen, bath), to dump any excess from the furnace. Plus, I'd put in a static damper between the plenum and the air return if necessary. Here are my three questions:
a) there are many, many companies that manufacture "zoning systems" -- I need perhaps three that I can research and pick the one I go with. Thus my question is: what is perhaps the most "home user friendly" system out there? One that is relatively easy to install and maintain for someone who is handy but not an HVAC professional.
b) Can anyone point me to resources, tools or calculation tables where I can plug in the btu output of my furnance, volume of the blower, number and size of my ducts and zone plan to determine if my system is properly configured?
c) Barring all else, a place where I can get a good recommendation on an HVAC contractor in Seattle who can act as a consultant on my project?
