Aeroseal cost for typical U.S. homes usually ranges from $600 to $3,500 depending on duct size, leakage level, and access. Buyers pay a base price per job plus possible add-ons for repairs, HVAC diagnostics, or complex duct runs; the main drivers are square footage served, number of leaks, and whether a full system test (blower door/duct blaster) is included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Aeroseal Duct Sealing (Whole-House) | $600 | $1,200-$1,800 | $3,500 | Assumptions: 1,200-2,500 sq ft home, accessible ducts, standard return/supply layout. |
| Partial/Single-Duct or Trunk | $200 | $400-$700 | $1,200 | Assumptions: single trunk or few registers, easy access. |
| Pre-seal Repairs & Access | $0 | $150-$600 | $1,200 | Assumptions: minor taping vs. sheet metal repair. |
| Testing (pre/post) & Diagnostics | $100 | $200-$350 | $600 | Assumptions: includes blower door and duct leakage test. |
Typical Total Price For Whole-House Aeroseal Duct Sealing
Most contractors quote a total Aeroseal price per job rather than strictly per sq ft; typical whole-house totals fall in a predictable band based on system size and leakage. Expect $1,200-$1,800 for an average 1,500–2,500 sq ft home with accessible ducts and moderate leakage.
Lower-priced jobs ($600-$900) are usually small systems, mild leakage, or promotional regional rates; high-end jobs ($2,000-$3,500) involve large homes, extensive pre-repair, attic/ crawlspace complications, or bundled HVAC upgrades.
Breakdown Of Main Quote Components for Aeroseal Jobs
| Materials | Labor | Equipment | Delivery/Disposal | Permits |
|---|---|---|---|---|
| $10-$60 (sealant, tapes) | $300-$1,200 | $150-$600 (machine amortized) | $0-$75 | $0-$150 |
Labor and machine time are the biggest cost components—expect crews to spend 2–6 hours on-site for typical homes.
How System Size and Leakage Rate Change the Final Quote
Two variables dominate price swings: ducted area (sq ft served or total linear feet) and pre-seal leakage measured in CFM25 or percent of conditioned floor area. Jobs under 1,000 sq ft with leakage under 20% of norm often cost $600-$900; systems over 3,000 sq ft or leakage above 40% can exceed $2,000-$3,000.
Numeric thresholds contractors use: less than 200 CFM25 (low), 200–500 CFM25 (medium), over 500 CFM25 (high). Another threshold is linear footage: under 100 linear ft (small), 100–300 (medium), over 300 (large) which affects access time and labor.
Repairs, Access Work, and When Prices Jump
Pre-seal repairs like replacing collapsed duct, sealing major gaps with mastic, or removing insulation add $150-$1,200 depending on scope. If technicians find sheet-metal damage, expect $300-$1,000 extra rather than a simple tape fix.
Limited access (buried ducts, narrow crawlspaces, ceilings) increases labor time and can add $200-$800 in access charges or require additional openings and re-sealing work.
Practical Steps To Reduce Aeroseal Price On Your Quote
Owners control scope and timing to lower cost: consolidate service with other HVAC work, schedule off-season service, and complete simple prep. Sealing or taping obvious visible gaps before the contractor arrives can lower pre-repair labor and reduce the total quote by $100-$400.
Additional cost-saving choices include accepting a targeted trunk-only seal ($200-$700) instead of whole-system sealing, and bundling with filter upgrades or HVAC tune-ups to negotiate package pricing.
Regional Price Differences And What To Expect Locally
| Region | Typical Range | Delta vs. National Average |
|---|---|---|
| Northeast / Metro | $1,200-$2,500 | +10% to +35% |
| Midwest / Suburban | $900-$1,600 | -5% to +5% |
| South / Sunbelt | $800-$1,700 | -10% to +5% |
| West Coast / High-Cost Cities | $1,400-$3,500 | +20% to +60% |
Assumptions: local labor rates, permit costs, and market demand. Urban areas typically run higher due to labor and travel. Expect the largest premiums in high-cost metro areas and the deepest discounts in lower-wage rural markets.
Real-World Quote Examples With Work Scope
| Example | Specs | Labor Hours | Price |
|---|---|---|---|
| Small Condo | 800 sq ft, 1 trunk, low leakage | 2 hours | $600 |
| Average Home | 1,800 sq ft, full system, moderate leakage | 4 hours | $1,500 |
| Large Home | 3,200 sq ft, multiple zones, high leakage, repairs | 6–10 hours | $2,800-$3,500 |
These examples reflect realistic mixes of labor, prep, and testing that shape most Aeroseal quotes.
