Aeroseal duct sealing cost typically ranges from $300 to $3,500 depending on home size, total leakage, and access. Buyers usually pay most often in the $700-$1,800 band for an average single-family home; major drivers are total leakage in CFM and the complexity of the duct network.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full-home Aeroseal | $300 | $1,200 | $3,500 | Assumptions: 1,200-2,500 sq ft home, typical leakage, Midwest labor rates. |
| Per Register / Room | $50 | $150 | $400 | Small localized sealing or single-branch runs. |
| Per Linear Foot (if quoted) | $4/ft | $7/ft | $12/ft | Used by some contractors for long runs or commercial ducts. |
What Homeowners Usually Pay For Full-Home Aeroseal Service
Typical total price for a whole-house job is $700-$1,800 for a 1,500-2,200 sq ft home with moderate leakage (4-8 air changes per hour prior to sealing). An average single-family Aeroseal job hits about $1,200 under normal access and no major repairs.
Assumptions: 1500-2200 sq ft, 10-16 registers, no major duct replacement, normal attic/crawl access.
Line-Item Quote Breakdown: Materials, Labor, Equipment, Permits
Typical contractor quotes include distinct line items; understanding them helps compare bids. Equipment and technician time are the largest single components on an Aeroseal invoice.
| Materials | Labor | Equipment | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $30-$200 | $300-$1,200 | $200-$800 | $0-$150 | $50-$400 |
| Sealant, tape, minor mastic | 2-8 hours per tech at $75-$125/hr | Aeroseal machine allocation or rental | Rare: old duct disposal | Repairs or extra access work |
How Specific Variables Like CFM50 Leakage and House Size Change Price
Two of the strongest price drivers are measured leakage (CFM50 or CFM@25) and conditioned floor area. Jobs with pre-seal leakage under 200 CFM typically fall in the low range, while 500+ CFM can push costs to the high end.
Numeric thresholds to expect: sealing improvement targets often aim for a 40%-90% reduction; contractors may charge more when pre-seal leakage exceeds 300-400 CFM or when house size is above 3,000 sq ft.
How Access, Duct Material, And Location Raise Or Lower Quotes
Access (attic vs. crawl vs. finished basement), duct material (flex vs. sheet metal), and how many sealed returns versus supply runs matter. Hard-to-reach ducts or ducts behind finished walls add $200-$1,000 in access work.
Assumptions: attic access is standard; sealed returns require more technician time.
Practical Ways To Reduce Your Aeroseal Price Before The Technician Arrives
Prepare ducts, consolidate access points, and do minor repairs: sealing obvious large gaps, clearing attic walkways, and labeling registers. Simple homeowner prep can reduce technician time by 1-3 hours, saving roughly $75-$375.
Other cost controls: bundle Aeroseal with a tune-up, compare 3 quotes, schedule off-peak season, and avoid unnecessary premium upgrades such as cosmetic return modifications.
Real-World Quote Examples With Specs And Pricing
Three example quotes clarify ranges and assumptions. These examples show how size, leakage, and access produce different totals for similar homes.
| Scenario | Specs | Labor Hours | Per-Unit Rate | Total |
|---|---|---|---|---|
| Small condo | 800 sq ft, 120 CFM pre-seal, 6 registers | 2 hrs | $120 per register | $300-$500 |
| Typical suburban home | 1,800 sq ft, 350 CFM, 12 registers | 4-6 hrs | $7/ft or $100-$150/register | $900-$1,500 |
| Large home with attic access issues | 3,200 sq ft, 700 CFM, complex runs | 8-12 hrs | $7-$12/ft or higher | $2,200-$3,800 |
Seasonal Timing, Labor Rates, And Typical Job Duration
Labor rates and scheduling affect final price: expect peak-season premiums in summer/fall for HVAC pros. Average job duration is 2-8 hours per technician; multiple technicians can shorten elapsed time but not total labor cost.
Typical hourly rates used in quotes: $75-$125 per hour per technician; single-tech jobs cost less in quoted hours but may take longer on-site.
Common Add-Ons, Repairs, And When Replacement Beats Sealing
Contractors commonly add costs for disconnected ducts, collapsed ductwork, major insulation replacement, or code-related repairs. If more than 25%-30% of the duct system needs replacement, replacement may be more cost-effective than sealing.
Expect repair add-ons of $200-$1,500 for moderate fixes; major duct replacement can exceed $4,000 and change the cost-benefit analysis.
