I currently have a 4,000 sq. ft home (including finished part of basement) that is split into two zones for heating and cooling. The zoning is accomplished via an electronic damper (there is a single furnace and a single outdoor A/C unit).
The bedroom level is one zone; and the 1st floor and basement are combined as the other zone.
The split between the zones is 40% for the bedroom zone; with the 1st floor/basement being 60%.
Now the basement has a self-contained home theater room. I have determined that due to the hot air being put out by the projector -- and the heat from 4 or more people's bodies in the room -- that the theater room really needs its own heating/cooling -- separate from the other zones.
This theater room is 16 x 20 (with a 7' 9" ceiling). The rest of the basement is about 500 sq feet (total for basement -- including theater room -- about 850 sq feet).
Would it be possible to take my existing Carrier Infinity zoning and add another zone -- JUST for the theater room. Giving me 3 zones: 1. bedrooms; 2. 1st floor and most of finished basement 3. basement theater room
Also, would it be possible to make the basement AND the theater room each have its own zone. In other words -- keep the bedroom level as one zone; make the main floor its own separate zone; then split the basement into two zones -- 1 for the main part of the basement and the other for the theater room?
Is this possible? Note that all ductwork is accessible via a drop ceiling in the basement.
If possible I can approach the HVAC company that installed everything for this house. But I wanted to see if this was even worth bringing up.
