do you have any links on how to splice up a HVAC to multiple zones?
You might be happy with very cheap, minimal effort battery & timer-controlled "vent-misers":

For the basic (manually adjusted) dampers, you can see the first segment of this video:

And the last 5 minutes of this one:

For an automatic zoning retrofit, it's easiest to find one of the forced-air zoning retrofit kits like the Honeywell TrueZone:

Though you can really do the same thing by buying a few line-level thermostats and motorized dampers, separately instead of depending on their expensive and advanced multi-zone thermostat systems that are part of the kit.

The high-tech pneumatic retrofit options might be easier to install (and therefore worth the extra expense) in some situations:

Well, at least that should be enough to get you started.
