Which option is right for you?
No ducts, an addition, finished basement/attic, hot/cold rooms, or you want best-in-class efficiency.
Existing ductwork is solid, you prefer the look of vents, and you want one thermostat for the whole house.
Multi-zone (one outdoor, multiple indoor) saves wall space; multiple singles offer redundancy if one fails.
