We're remodeling our Atlanta, GA, house, which means replacing the HVAC system. The house has a 1500 sf main floor with a 1500 sf daylight basement (only one wall is fully against ground). I would like to use a dual-fuel heating system (heat pump/gas) with regular a/c. The stairwell between the two floors will be open.
We found this article (attached) in the summer 2008 Fine Homebuilding that recommended this setup as a possible replacement for a zoned system. The HVAC contractors we've spoken with say they've never heard of such a setup.
My questions: Could this work? Is this setup common in other parts of the country? Or should I stop buying Fine Homebuilding and get a zoned system?
Thanks to everyone for your help!
