Homeowners typically pay between $300 and $3,800 for air duct sealing and Aeroseal cost depending on house size, leak severity, and access. The main cost drivers are the chosen method (manual mastic/foil vs. Aeroseal aerosol), total duct leakage (CFM lost), crew time, and whether repairs or insulated replacements are needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Manual Duct Sealing (whole house) | $300 | $800 | $1,800 | Assumptions: 1,500–2,500 sq ft home, minor access work. |
| Aeroseal Whole-House | $800 | $1,800 | $3,800 | Assumptions: 1,500–2,500 sq ft, moderate leaks (15%–40% leakage). |
| Per-Unit / Per-Register | $75 | $150 | $400 | Per register or short run for targeted sealing. |
| Per Linear Foot (manual) | $4/ft | $6/ft | $9/ft | Assumptions: exposed main/branch ducts, standard materials. |
Typical Air Duct Sealing Price For a 1,500–2,500 sq ft Home
Most U.S. quotes cluster around $300-$1,800 for manual sealing and $800-$3,800 for Aeroseal on a typical 1,500–2,500 sq ft single-family home. Expect Aeroseal averages to be about 2–3× the cost of a basic hand-seal job but often deliver larger leakage reductions.
Assumptions: Midwest labor rates, standard HVAC access, no major duct replacement.
Line-Item Costs For Materials Labor Equipment Disposal
| Materials | Labor | Equipment | Permits | Disposal |
|---|---|---|---|---|
| $20-$200 (mastic, foil, tape) | $150-$1,200 (labor hours × hourly rate) | $0-$1,500 (Aeroseal machine rental or contractor fee) | $0-$200 (local permits if required) | $0-$150 (minor debris) |
Labor is often the largest line item; expect $75-$125 per hour for certified HVAC techs in many markets.
Assumptions: job requires 2–10 labor hours, Aeroseal equipment fees included in contractor price when used.
How Leak Area Duct Length And Access Level Change Price
Leak area measured in sq in or percent of total CFM, duct length in linear feet, and access level (attic vs. basement vs. duct chase) are primary variables. If total leakage exceeds ~20% of system CFM or access requires tearing ceilings, prices jump sharply.
- Small leaks (<10 sq in total or <10% leakage): add $0-$400 to a service call.
- Moderate leaks (10–40 sq in or 10%–30% leakage): typical Aeroseal or combined approaches $800-$2,000.
- Severe leaks (>40 sq in or >30% leakage): $2,000-$3,800+, possible duct repair or replacement required.
Assumptions: CFM-based thresholds assume 1,000–2,000 CFM system capacity and standard residential ductwork.
Reduce Air Duct Sealing Price By Controlling Scope And Materials
Buyers can lower the final price by limiting the sealed area, prepping access points, and choosing targeted register sealing instead of full-system Aeroseal. Doing homeowner prep (clearing attic space, labeling returns) can cut contractor time by 1–3 hours.
- Target only high-leak runs instead of whole-house sealing to save 30%–60% on total cost.
- Opt for mastic and foil on exposed mains ($4–$9/ft) instead of full Aeroseal when leaks are localized.
- Schedule work off-peak season to find lower hourly rates or discounts.
Assumptions: homeowner willing to accept smaller leakage reduction in exchange for lower cost.
Regional Price Differences Between Urban Suburban And Rural Markets
Prices vary by region: urban coastal areas and high-cost metros run 10%–40% above national averages; rural areas often undercut by 10%–25%. Expect $900–$2,500 average Aeroseal prices in expensive metros and $700–$1,600 in lower-cost regions.

What Aeroseal Adds To Cost Per Duct And Per Home
Aeroseal pricing is commonly quoted as a whole-home package or per major run. Typical Aeroseal per-home pricing is $800-$3,800, while per-duct or per-register treatments run $75-$400 each for targeted jobs.
- Whole-home Aeroseal: $0.50-$2.00 per sq ft; thus $750-$2,500 on a 1,500–1,800 sq ft home.
- Per run or trunk sealing: $150-$600 for a major trunk depending on length and leakage.
- Minimum call/diagnostic fee often $75-$200 applies before Aeroseal work.
Assumptions: Aeroseal dealer pricing includes setup, pre/post leakage testing, and labor for machine operation.
Typical Labor Time Crew Size And Hourly Rates For Sealing Jobs
Most duct sealing jobs take 2–10 hours. Aeroseal whole-house jobs typically require 3–6 hours plus setup. Typical crew: one technician with an assistant; larger HVAC remodels may need 2–3 techs and more time.
- Hand-sealing: 2–6 hours, 1–2 techs.
- Aeroseal whole-house: 3–8 hours, 1–2 techs.
- Hourly rates: $75-$125/hour; emergency or weekend rates may be higher.
Assumptions: standard residential systems, no major access demolition required.
Three Real-World Quote Examples With Specs And Totals
- Small bungalow, 1,200 sq ft: Manual sealing of visible trunk runs, 3 labor hours, materials $50 — Quote $350. Assumptions: attic access easy, minor leaks.
- Suburban 1,800 sq ft home: Aeroseal whole-home to reduce 25% leakage, 5 hours, Aeroseal fee included — Quote $1,600. Assumptions: average access, includes pre/post test.
- Larger two-story 3,000 sq ft with poor access: Trunk repairs $900 + Aeroseal $2,200 — Quote $3,100. Assumptions: attic tight, significant branch leakage.
These examples show how square footage, access difficulty, and whether repairs are needed push totals across the low-average-high ranges.
