Buyers typically pay $4,000-$12,000 for a complete ducted split system installation, with size, ductwork condition, and brand driving most of the variation. This article explains ducted split system price ranges, per-ton and per-square-foot assumptions, and the specific line items that appear on a contractor quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete 2–3 Ton System Installed | $4,000 | $7,500 | $12,000 | Assumptions: Single-story 1,200–2,000 sq ft, existing ductwork in good condition. |
| Per Ton Installed | $1,500 | $2,500 | $4,000 | Includes equipment and labor, varies by efficiency and brand. |
| New Ductwork (per sq ft) | $4 | $7 | $12 | Assumes moderate complexity and average insulation. |
| Zone Dampers / Controls (per zone) | $300 | $600 | $1,200 | Per zone installed; smart thermostats extra. |

Typical Installed Prices For Ducted Split Systems by Size
Most homeowners pay by system tonnage: 2–3 ton for small homes, 3–5 ton for medium homes, 5+ ton for large homes.
2.0–3.0 ton complete installed: $4,000-$8,000 (common for 1,000–2,000 sq ft). 3.0–4.0 ton: $6,000-$10,000 (2,000–3,000 sq ft). 5.0+ ton: $9,000-$16,000 (3,000+ sq ft or homes with high ceilings). Assumptions: Standard 13–16 SEER equipment, typical access, normal ducting.
Line-Item Cost Breakdown Contractors Usually Quote
A full quote typically separates equipment, ductwork, labor, permits, and disposal so buyers can compare line-by-line.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $1,500-$6,000 (units, coils, controls) | $1,200-$4,000 | $300-$1,200 (cranes, lifts, bracketing) | $50-$600 (local) | $100-$800 (old unit removal) |
How Ductwork Condition Changes the Final Price
Replacing or sealing ducts is one of the costliest add-ons and can double labor and material costs compared with using existing ducts.
Minor repairs/sealing: $300-$1,200. Partial replacement (select runs): $1,500-$4,000. Full duct replacement: $4-$12 per sq ft installed, or $6,000-$15,000 for an average home. Assumptions: typical 8–10 supply/return runs, attic or crawlspace access.

Technical Variables That Strongly Drive the Quote
Two variables with clear numeric thresholds are unit tonnage and total duct linear footage; each increases cost at predictable breakpoints.
Unit tonnage: moving from 3.0 to 4.0 ton often adds $1,000-$2,000 in equipment cost. Duct length: runs under 100 linear ft add little; 100–300 linear ft add $1,000-$3,000; over 300 linear ft may add $3,000-$7,000 due to materials and labor. Other drivers: SEER rating (each 1–2 SEER upcharge ≈ $200-$800) and number of zones (each extra zone $300-$1,200).
Practical Ways To Reduce the Ducted Split System Price
Controlling scope — reuse ducts, choose moderate SEER, and schedule outside peak season — yields the largest savings without sacrificing basic performance.
Tips: reuse existing ducts if sealed and insulated; select 14–16 SEER instead of premium 20+ SEER; bundle with other home projects to negotiate labor; get 3 written quotes; schedule installation in spring or fall to avoid summer rush. Typical savings: $500-$3,000 depending on scope choices.
Regional Price Differences Across the U.S.
Regional labor and permit costs create predictable deltas: expect 10–25% higher prices in coastal metro areas versus the Midwest.
Example deltas: Midwest baseline. Northeast/West Coast: +10% to +25%. Mountain/Rural areas: -5% to +5% depending on access. Urban installs may add $300-$1,000 for parking, lift permits, or traffic logistics.

Common Add-Ons, Timing, and Labor Time To Budget For
Typical install time ranges 8–24 hours for straightforward jobs; complex replacements with ductwork can take 2–5 days.
Diagnostics/inspection fee: $75-$200. Minimum service charge or trip fee: $75-$150. Overtime or rush: +25%–50%. Crew size: 2–4 technicians. Labor rates: $75-$125 per hour commonly; total labor hours usually 10–40 depending on complexity.
