Air duct inspection cost typically ranges from $100 to $600 for standard homes, driven by home size, inspection type, and accessibility. This article lists low-average-high pricing, per-unit rates where relevant, and the main factors that change a final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic visual inspection | $75 | $150 | $300 | Single-family, no cameras |
| Camera/video inspection (per run) | $100 | $250 | $600 | Includes report and images |
| Whole-house duct inspection | $150 | $300 | $600 | Up to 3,000 sq ft; add for complicated runs |
| Mold or contamination testing | $150 | $350 | $750 | Lab fees often extra |
Typical Total Price For a Whole-House Air Duct Inspection
Assumptions: Typical single-family home, 1–3 HVAC runs, normal attic/crawlspace access.
Most homeowners pay $150-$300 for a whole-house inspection; more thorough camera inspections cost $250-$600.
Low: $75-$150 for a basic visual and static check. Average: $150-$300 for camera inspection of main runs in a 1,500–2,500 sq ft home. High: $300-$600 or more when multiple systems, long runs, or contamination testing are required.
How The Quote Breaks Down By Materials, Labor, Equipment, and Disposal
Inspectors typically itemize inspection fee, equipment charge, lab/testing, and travel or minimum service charges.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $0-$50 (consumables) | $75-$200 (flat or hourly) | $50-$400 (camera rental amortized) | $0-$50 (rare) | $0-$100 (cleanup) |
Which Site Conditions And Specs Drive Price Changes Most
Accessibility, number of duct runs, and need for airborne testing are the top variables that change price substantially.
Examples with numeric thresholds: hard-to-reach attic/crawl access adds $50-$200; homes over 3,000 sq ft typically add $100-$300; each additional HVAC system/air handler adds $75-$250.
Special testing: mold spore or particle lab testing adds $150-$500 depending on number of samples; HVAC sealing or cleaning recommendations add inspection-to-repair conversions often doubling the bill.
Practical Ways To Lower Your Air Duct Inspection Price
Combining services and preparing spaces reduces time on site and lowers total cost.
- Bundle inspection with annual HVAC service or duct cleaning for a package rate: expect $100-$250 savings versus separate bookings.
- Clear attic/crawlspace access and label registers to cut technician time by 10–30%.
- Skip camera runs on short, visible trunks if a visual check is acceptable—saves $100-$300.
- Request hourly labor estimates and caps; typical rates: $75-$125 per hour.
Regional Price Differences: How Much More Or Less Will You Pay?
Urban and high-cost states run 10–30% higher than Midwest or rural markets for the same inspection scope.
Typical deltas: Northeast/West Coast +15–30% vs. Midwest baseline; Sunbelt metro areas +10–20% during peak HVAC season. Rural areas often have travel minimums ($75-$150) that raise the effective rate for small jobs.
Extra Fees, Add-Ons, And What Typically Isn’t Included
Expect extra fees for lab testing, confined-space work, long runs, and accessibility work.
- Camera video per run: $100-$600 depending on run length and resolution.
- Mold/contaminant lab samples: $150-$500 total; individual sample $30-$80.
- Detailed report with images and estimates: $50-$200.
- After-hours or emergency inspections: +25–50% surcharge.
Sample Real-World Quotes With Specs And Labor Estimates
Three representative quotes show how scope and access change price.
| Scenario | Specs | Labor Hours | Price |
|---|---|---|---|
| Basic visual, 1,400 sq ft home | Single system, attic access | 1–1.5 hrs | $100-$175 |
| Camera inspection, 2,500 sq ft | 2 systems, 3 runs, images | 2–3 hrs | $250-$450 |
| Full mold testing + camera, 3,500 sq ft | 3 systems, 6 samples, reports | 3–5 hrs | $500-$1,000 |
When An Inspection Turns Into Repair Or Cleaning: Cost Transition Points
Small fixes keep costs low; major cleaning or sealing shifts price into the hundreds or thousands.
Examples: minor sealing of gaps: $100-$400; professional duct cleaning for a whole house: $300-$900; full system repair or replacement sections: $200-$1,500 depending on materials and access. Ask for separate line items to compare inspection versus remediation.
