So if they ask people to cut back on electricity use, can you cut back AC to just a few rooms to chill in? Or are you stuck with the whole house?

    Cool. Do the dampers have automatic controls on them? Does it work with heat too?

      Typically it’s a single air handler and one set of ductwork for both the furnace and the AC, so the damper is used in both cases.

      The control board is the brain behind everything working together…it knows what zones are calling for service, opens/closes the appropriate dampers, tells the HVAC unit what to do and how fast to run the blower.

      It’s all automated, I just set the heating/cooling thresholds and schedules on the thermostats.

      The main problems are the single points of failure…the HVAC unit and the control board primarily. Lose either one and you have no climate control at all.

      Mini-Split ductless systems are becoming more popular here tho. It wouldn’t surprise me if they become the standard for new builds in 20 years.
