I have a two story house and a single HVAC unit with the thermostat and air intake in the upstairs hallway. Our downstairs always lags the upstairs (downstairs is colder in winter, hotter in summer), and I was looking at multi-zone solutions. All ducting is in the attic, so if I wanted to, I could do a legit dual-zone retrofit with automated dampers (like this: http://www.homedepot.com/p/Suncourt-10-in-A, utomated-Damper-Normally-Closed-ZC110/203227241) and whatever controls I need and static pressure issues I induce. Or I could just take the easy way out and buy an ecobee3 which has external wireless sensors, but forces all air through the attic and incurs whatever losses that involves. Thoughts? Up front cost of dual-zone retrofit vs. long term cost of running fan to force air through hot/cold attic ducting?
