Need opinions re electronic zoning systems
I've got a 3800sqft, two story home with a Trane furnace and heat pump. Don't know much about HVAC, but I've got three main ducts that branch out of the basement furnace: 2 feed the main floor and 1 shoots up into the attic to feed the second floor.
Even using the dampers, the system has never run very efficiently and there is a big temp difference on the two floors, so a number of HVAC contractors have recommended electronic zoning systems.
I'm trying to decide between two systems. The first is an Arzel pneumatic damper system that I can have installed for about $2800. The second is a Green Zone mechanical damper system (made by Jackson Systems) that I can get installed for $1800. Both have 10 year warranties.
I know the Arzel's pneumatic damper system is superior, but is it worth paying an extra $1000? Any thoughts would be appreciated.
