Aeroseal duct sealing costs typically include a combination of service fees, duct system size, and access conditions. The price you pay for an Aeroseal job depends on home size, duct length, number of vents, and whether testing or warranty is included. This article shows the actual cost ranges and what drives them, so buyers can budget accurately for a sealing project.
Assumptions: Midwest to Southeast labor rates, standard fiberglass or metal ductwork, normal accessibility, and a typical four-bedroom, two-story home.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total project | $450 | $900 | $2,000 | Residential duct sealing with Aeroseal method |
| Per-duct-seal estimate | $80 | $150 | $350 | Subject to duct length and complexity |
| Testing & verification | $50 | $150 | $300 | Pressure tests, airflow measures |
| Warranty options | $0 | $100 | $300 | 1–5 year terms |
Aeroseal Duct Sealing Price Snapshot by Home Size
Prices vary with home size and duct network complexity. A small home may fall on the lower end, while large or multi-zone systems reach the higher end of the range. Typical total pricing for a standard single-family home is $650-$1,400, with larger homes or complex layouts pushing toward $1,800 or more.
Major Cost Components in an Aeroseal Quote
Quotes break down into materials, labor, equipment use, and follow-up services. Materials and reagents are usually a small share compared to labor time and equipment setup.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $20 | $60 | $120 | Sealant, adapters, tapes |
| Labor | $250 | $520 | $1,050 | Qualified technician hours |
| Equipment | $60 | $120 | $350 | Sealant delivery system, testing gear |
| Testing/Verification | $50 | $150 | $300 | Airflow and pressure checks |
| Permits/Fees | $0 | $50 | $150 | Usually optional or regional |
| Delivery/Disposal | $0 | $10 | $60 | Transport and waste handling |
| Warranty | $0 | $100 | $300 | Limited coverage options |
Two numeric drivers commonly shift quotes: duct run length and number of vents. Longer duct runs add time and materials, increasing cost per zone.
Residential homes with 40–60 feet of ductwork per zone cost less than homes with 150+ feet per zone. A single-story, open-plan layout often seals faster than a multi-story maze. Expect per-zone pricing to rise with run length.
Hard-to-reach plenums or collapsed sections require extra labor and adapters, lifting the price. Limited access can add 20–40% to labor time.
Prices shift with regional costs and demand. In the Northeast and West Coast, higher labor rates and scheduling demand can push averages toward the upper end. Midwestern markets often show moderate pricing with stable demand.
West Coast: $800-$1,800; Northeast: $750-$1,600; Midwest: $650-$1,350; South: $600-$1,400. Assumptions: standard residential ductwork, normal access, standard warranty options.
Cost-conscious choices focus on scope, timing, and material options. Scheduling in shoulder seasons can lower crew availability costs.
Seal only active zones first, postpone optional testing, and bundle with other HVAC updates when possible. Consolidated projects reduce mobilization fees.
Use manufacturer-recommended components and limit extra adapters. Conduct pre-cleaning of ducts to shorten sealing time. Pre-work reduces post-inspection time and surprises.
Below are three representative quotes for common setups to help buyers anchor expectations. Each example assumes standard 8–10 vents and typical 60–100 feet of ducting per zone.
| Scenario | Total Price | Labor Hours | Per-Vent | Notes |
|---|---|---|---|---|
| Small 1,800 sq ft ranch, 2 zones | $650-$1,050 | 4–6 | $60-$90 | Standard metal ducts |
| Mid-size 2,400 sq ft two-story, 3 zones | $1,000-$1,650 | 6–9 | $80-$120 | Accessible plenums |
| Large 3,200+ sq ft with complex runs | $1,400-$2,300 | 9–14 | $100-$150 | Extended duct length, multiple zones |
Manual sealing with mastic or foil tape is typically cheaper upfront but may require ongoing maintenance. Aeroseal provides a one-pass sealing approach with quantified leakage reductions and a fixed service window.
Unexpected duct damage, non-standard sizes, or restricted access can raise quotes. Budget a contingency of 5–15% for field changes.
