How Much Does It Cost to Redo Ductwork: Typical Price Ranges 2026

Redoing ductwork typically costs $2,000-$12,000 for most U.S. homes depending on scope, with materials, labor, and access driving price. This article explains typical ductwork cost ranges, per-foot rates, and the key factors that change a duct replacement price so buyers can budget and compare quotes.

Item	Low	Average	High	Notes
Full house duct replacement (1,200–2,500 sq ft)	$2,000	$6,000	$12,000	Assumptions: single-story or attic access, mix of flex and metal ducts.
Per linear foot (new duct)	$4 per ft	$8 per ft	$15 per ft	Depends on material and installation difficulty.
Register/boot replacement	$25	$75	$200	Per register, includes new collar and trim.
Sealing & repairs	$200	$800	$2,500	Includes mastic, tape, targeted repairs.

Typical Total Price For Full-Home Duct Replacement

Most whole-home duct replacements cost $2,000-$12,000 with a U.S. average near $6,000 for a 1,500–2,000 sq ft house. Expect roughly $4-$10 per linear foot installed for standard flex duct and $8-$15 per linear foot for sheet metal.

Assumptions: Midwest labor rates, standard materials, normal access.

Breakdown Of Major Quote Components

A standard contractor quote separates material, labor, and equipment charges plus disposal and permits where required. Understanding each component helps compare line-item quotes accurately.

Materials	Labor	Equipment	Delivery/Disposal	Permits
$300-$4,000 (flex, metal, insulation)	$500-$6,000 ()	$50-$600 (scissor lifts, ducts crimpers)	$50-$700 (debris haul)	$0-$800 (local codes)

How Material Choice Changes The Price

Material selection shifts both unit price and longevity: flex duct is cheapest, sheet metal is durable and expensive, and pre-insulated or ductboard adds cost. Typical per-foot installed: flex $4-$8/ft, sheet metal $8-$15/ft, pre-insulated $10-$20/ft.

Assumptions: includes connectors, collars, basic insulation.

Site Conditions That Drive Large Price Swings

Access and location add big variability: attic or crawl access is cheaper than inside finished ceilings or walls. Expect a 20%-50% premium when ducts run through walls or require drywall repair.

Key numeric thresholds: jobs under 100 linear feet tend to have minimum charges ($500-$1,200); jobs over 500 linear feet may drop per-foot rate by 15%-30%.

Specific Technical Variables That Change Your Quote

HVAC tonnage, number of runs, and register count alter labor and material needs. Two niche drivers: replacement for systems 3+ tons typically needs larger trunking and costs an extra $500-$1,500; more than 12 supply runs often raises labor by $300-$1,200.

Also consider required airflow balancing (CFM tuning) or re-sizing: rebalance services commonly add $150-$600.

Practical Ways To Reduce Duct Replacement Price

Control scope, timing, and materials: stage work during off-season, keep existing trunk if usable, choose flex ducts where appropriate, and do basic prep like clearing attic obstructions. Removing unnecessary register relocations, bundling with HVAC work, and getting three itemized bids often saves 10%-25%.

Avoid costly last-minute changes and request contractor schedules to minimize overtime or rush fees.

Regional Price Differences And What To Expect

Prices vary by region: urban coastal areas run 10%-30% higher than Midwest and rural markets. Typical adjustment: add 15%-25% in West Coast and Northeast metro areas relative to national averages.

Region	Low	Average	High
Midwest/Suburban	$2,000	$5,500	$9,000
Northeast/West Coast	$2,500	$7,000	$12,000
Rural	$1,800	$4,500	$8,000

Typical Job Durations, Crew Size, And Labor Rates

Most full-home duct redos take 1-5 days; small repairs are a few hours. Expect crew sizes of 1-3 techs and hourly labor rates of $75-$125 per hour depending on skill and region.

Example: 2 techs × 24 hours × $95/hr ≈ $4,560 labor.

Real-World Quote Examples With Specs

Concrete examples help set expectations. Each example lists materials, labor hours, per-unit costs and total.

Scenario	Specs	Labor	Per-Unit	Total
Small repair	40 ft flex, 4 registers	4 hours, 1 tech	$6/ft installed	$400-$600
Standard full replace	300 ft mixed flex, 12 registers	24 hours, 2 techs	$8/ft avg	$3,500-$6,500
High-end remodel	500 ft sheet metal, custom boots	48 hours, 3 techs	$12/ft installed	$8,000-$12,000

Common Add-Ons That Increase Final Price

Frequent extras include aerosol sealing, insulation upgrades, smoke/combustion air changes, and register replacement. Add-on pricing: aerosol seal $400-$1,200, insulation wrap $1-$3 per ft, register replacement $25-$200 each.
