Built a house in CS recently, and we have two AC units.
One unit heats/cools common areas (kitchen, dining, laundry, great room, game room) in roughly half of the house.
The other unit is split into separate zones for 4 bedrooms and an office. Each of these rooms has its own thermostat and return air. Cost $700 to add this functionality.
Best investment ever. Our kids or guests can set their bedroom to whatever temp they like, and it's contained to that room. I can hang out in my office/man-room comfortably while my wife chills the master BR down to sub-zero.
They install an electronic circuit board in the attic that controls how much air each room gets -- and for how long -- to keep it at the desired temp.
Pete Morgan with Morgan Air Conditioning did the work.
$700 seems really cheap. A good control board and 4 dampers cost that alone.
Do you know what brand the control board and dampers are ?
Keep in mind this was new construction. The total AC/heat package (installation, ductwork, etc.) was just over $30k for a large single story just under 4kSF. The initial zone estimates were $1,200 each, but the common area side of the house didn't need one. And he was able to zone the other one with less control boards, etc than he originally thought, and it saved me $500, for a net zone cost of $700.
The AC brand was Bryant, and it was their evolution series.
