The deciding factor is almost always your existing ductwork. A home with a furnace and sound ducts can usually add a central AC coil to what is already there, which is the lower-cost path. A home with baseboards, radiators, or an addition the ducts never reached is better served by ductless heads, because running new ductwork often costs more than the equipment.
When does ductless win?
Ductless earns its premium where ductwork is absent, inadequate, or expensive to extend, and where room-by-room control genuinely matters.
- Homes with electric baseboards or hot water heating and no ducts
- Additions, suites, and converted attics or garages
- Heritage homes where opening walls for ducts is invasive
- Households wanting different temperatures in different rooms
- Rental suites where separate control matters
When does central air win?
If the ducts are already there and in good condition, central is usually less expensive per unit of cooling, it is invisible, and it conditions the whole house from one thermostat. It also handles filtration for the whole home in one place, which matters during smoke season.
What do people get wrong?
The most common error is assuming existing ducts are adequate because they exist. Ducts sized for heating alone often cannot carry the airflow cooling needs, so a central AC added to marginal ductwork underperforms and can freeze.
The second is head count on ductless. One oversized head fighting to condition three rooms will short cycle and dehumidify poorly. Correct design usually means more heads at lower capacity.
Because we fabricate ductwork ourselves, we have no incentive to steer you toward ductless to avoid duct work, or toward central to sell metal. We measure what your ducts can carry and tell you.
