Quick answer: Ductless mini-splits cost $3,000–$8,000 per zone ($8,000–$15,000 for 3–4 zones); ducted heat pumps cost $8,000–$18,000 whole-home. Have good ductwork? Ducted is usually cheaper overall. No ducts? Ductless wins — adding ducts ($5,000–$10,000) erases the ducted advantage.

Head-to-Head Cost (2026)

Head-to-head cost comparison of ductless versus ducted heat pumps in 2026

	Ductless (mini-split)	Ducted (central)
Typical installed cost	$3,000–$8,000/zone; $8,000–$15,000 multi-zone	$8,000–$18,000 whole-home
Needs ductwork?	No	Yes (add $5,000–$10,000 if none)
Install time	1–2 days	2–4 days
2026 federal credit	$0 (25C ended)	$0 (25C ended)

Efficiency Comparison

Diagram showing ducted systems losing 20 to 30 percent of energy through duct leaks versus ductless room-by-room delivery

Factor	Ductless	Ducted
Real-world efficiency	Higher — no duct losses (ducts leak 20–30% of energy)	Good, but duct losses are real
Zoning	Room-by-room (don’t heat empty rooms)	Whole-home (zoning dampers add $2,000–$4,000)
Filtration	Basic per-head filters	Whole-home filtration/humidification possible

Ductless typically uses 20–30% less energy for the same comfort — the savings come from zoning + no duct losses, not magic.

Aesthetics & Comfort Trade-offs

Ductless: wall heads visible in every room; some owners dislike the look (ceiling cassettes cost more). Room-by-room temperature control is genuinely better.
Ducted: invisible (vents only), even temperatures, better air filtration options. But you’re heating/cooling the whole house to condition one room.

The Decision Framework

Decision framework infographic for choosing between ductless and ducted heat pumps

Choose ductless if: no existing ductwork · you want room-by-room control · addition/garage/ADU · old house where ducts are impractical.

Choose ducted if: good existing ducts · you value invisible equipment + whole-home filtration · large open-plan home.

The math that decides it: Get both quotes. If (ducted quote) < (ductless quote + nothing), and ducts are in good shape → ducted. If you need $5,000–$10,000 of new ductwork → ductless almost always wins.

Hybrid Approach (Increasingly Common)

Ducted heat pump for the main house + one ductless head for the problem addition/garage. Costs $10,000–$20,000 combined but solves the “one cold room” issue permanently.
