Depends alot on the layout of the home and cost/ability to run ductwork that is zoned with one system. Having 2 systems though allows for greater comfort than trying to do the whole house as one unzoned system.
What is the proper terminology when refering to two separate systems? I was under the impression that zoning was a single system with multiple thermostats and dampers to control where and when the air should go. Are two separate systems a type of zoning also?
I used to live in a townhouse and was never able to cool the 2nd floor enough. I can see if a system were in the attic with all local duckwork then I would have a much better chance.
I have a new house which I'm not totally moved in yet. I want to make sure that I can heat and cool to my comfort level. I would be willing to spend 5K or so beefing up the system if it does not do the job. As far as duct work goes If need be I can get a duct anywhere it's required. I'm comfortable with a reciprocating saw, Dry wall work and a paint brush. My wife does the spackling.
