What is involved in converting a single zone HVAC to a dual zone system using one compressor? Given all my existing parts will remain and no new condensor or evaporators will be added, I assume it will require a baffle/damper to direct the air to up/down/both areas depending on which thermostat get triggered. What parts best suit this type conversion? Is there an intermediate circuit board which would be required?
