    We currently live in a 3200SF home serviced by 2 HVAC's. We are in the process of relocating to a similar climate and don't want to go back to a single HVAC. We are looking for a similar sized house or bigger. We believe the two zones offer great advantages to one. My question is: If we found a house that didn't have two separate units, is it possible to retrofit a house to have two separate zones and units?

    Thanks,

    Gretchen

    Usually ,yes,if a single story with a large attic,like in our area.If the duct system is even partially between floors then probably not without removing the drywall.


    Also check into "zoning" systems,one unit with 2 or more zones each with it's own stat.Carrier's Infinity Zoning with two stage heating and cooling is one the best for existing duct systems.

    Try Zoning, why do you like two systems?

    You can do anything you want if you have the time and money. You ask a tough question to answer. But to your hypothetical question the answer would be yes you can...

    My question is: If we found a house that didn't have two separate units, is it possible to retrofit a house to have two separate zones and units?

    To what degree of perfection and to what level of efficiency is just a guess.
