Bottom Line
Verdict
Ducted systems ($6,000–$14,000) cost more to install but provide consistent whole-home heating and cooling with no visible indoor units and superior aesthetics. Split systems ($800–$5,000 for multi-head) are cheaper, easier to install in existing homes, and can be zoned by room. Ducted is better for new builds and homes with good roof space access. Split systems are better for apartment retrofits, homes with concrete ceilings, or situations where only some rooms need climate control.
Choose ducted for new constructions, renovations with accessible ceiling cavities, or homes where consistent temperature across all rooms is a priority. Choose split systems for apartments, homes without ceiling access for ductwork, situations where budget is a primary constraint, or where only 2–3 rooms need air conditioning. For whole-home coverage in an existing home with good roof access, ducted is generally the better investment once the higher installation cost is justified by improved aesthetics and comfort consistency.
Comparison FAQ
ActronAir is cheaper on average in this comparison, but the right answer depends on your specific requirements including house size, number of zones, existing ductwork condition, and local installer pricing.
House size, number of heating zones, existing ductwork condition, gas vs reverse cycle technology choice, star energy rating, and installer experience usually affect the total cost and value more than a blended average. Always confirm what is included in the supply-and-install price, the warranty terms, and ongoing service availability.
