Head-to-Head Cost (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

| 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

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.
