Aeroseal Duct Sealing Cost: Price Guide 2026
Aeroseal duct sealing costs typically depend on system size, home layout, duct accessibility, and whether a whole-house or targeted application is performed. The main cost drivers are equipment use, labor time, and any required prep work or testing. This article presents cost ranges in USD and explains where the money goes for a standard USA project.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total project | $1,200 | $2,500 | $6,000 | Factors include home size, number of ducts, and access |
| Per-duct zone pricing | $150 | $400 | $900 | Typically applies when only portions are sealed |
| Audit & testing | $100 | $300 | $600 | Blower door tests or thermography may be optional |
| Labor | $800 | $1,800 | $4,000 | Includes setup, sealing, and clean-up |
| Materials & equipment | $100 | $350 | $800 | Adhesives, inspection tools, and dye |
Assumptions: region, house size, duct layout, and crew availability.
Overview Of Costs
The Aeroseal cost range for a typical US home falls between $2,000 and $5,000, with common projects landing around $2,500-$3,800 for an average-sized house. For smaller homes or compact ductworks, costs can dip toward the low end, while larger residences, complex duct networks, or multi-zone sealing can push above $5,000. The exact price hinges on duct length, number of runs, accessibility, and whether prior sealing attempts were made. Total project ranges and per-unit estimates are provided with clear assumptions.
Cost Breakdown
Sealing projects combine labor, equipment use, and potential testing; a table below shows typical allocations.
| Components | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $100 | $350 | $800 | Sealant, dye, and consumables |
| Labor | $800 | $1,800 | $4,000 | Typically 8–20 hours depending on size |
| Equipment | $50 | $150 | $350 | Air-sealing unit rental or use |
| Testing & verification | $100 | $300 | $600 | Airflow, pressure, and leak check |
| Permits & inspections | $0 | $0-$150 | $300 | Region-dependent |
| Delivery/Removal of debris | $0 | $50 | $200 | Clean-up after service |
Pricing Variables
Key price drivers include duct length, number of zones, and accessibility. Longer runs increase material usage and labor time, while multiple zones multiply setup and sealing steps. HVAC specifics such as duct size and complexity affect per-unit pricing. For example, larger homes with extensive duct networks and difficult access typically push costs toward the high end, whereas straightforward, single-story layouts stay closer to the average range. Labor hours × hourly rate is a helpful formula for rough estimates.
Regional Price Differences
Prices vary by region due to labor markets and demand. In the Northeast urban markets, projects may run 5–15% higher than national averages. The Midwest tends to align with national averages or slightly below, while the South and rural areas can be 5–12% lower on typical jobs. These deltas reflect local wage rates, travel time, and contractor availability. Assumptions: region, property age, and access levels.
Labor, Hours & Rates
Labor is a major portion of the cost; sealing crews commonly bill by crew size and hours. Typical crews of 2–3 technicians work 6–14 hours for a standard home, with longer hours for larger or multi-zone systems. Hourly rates commonly range from $85 to $160, depending on region and crew experience. When scheduling, ask for an estimate that itemizes labor hours and per-hour rates. Labor hours × hourly rate offers a practical cross-check.
Additional & Hidden Costs
Some projects incur extra charges beyond base sealing. Access fees for attic or crawlspace work, extra sealant for stubborn leaks, or post-work adjustments may appear. If a thermography scan or blower door test is requested, expect additional fees. Permits and inspections are region-dependent and can add 0–$300. Reserve a contingency of 5–10% for unforeseen access issues or additional sealant needs. Assumptions: project scope and access constraints.
Ways To Save
Smart planning can reduce Aeroseal costs without compromising results. Bundle duct sealing with other HVAC services to reduce mobilization fees. If only certain zones are leaky, seal those zones first rather than the entire system. Obtain multiple quotes, ensuring each estimate includes a detailed breakdown of labor, materials, and any testing. Scheduling during off-peak seasons may also yield modest price relief. Assumptions: scope definition and contractor selection.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes for different home profiles.
- Basic – Small, single-story home with 1,000–1,200 sq ft, few duct runs, straightforward access. Assumptions: 8–10 hours, one zone, standard ducts. Labor: 8–10 hours @ $100/h; Materials: $150; Equipment: $100; Total: about $1,800–$2,200; per-duct: $180–$220.
