Indoor air quality, HVAC energy efficiency, and long-term system health all depend on clean air ducts. Yet the first question every homeowner asks is the same: “What is the average cost for duct cleaning?” At CountBricks, we answer that every day—instantly—through our AI voice estimating platform. Below we break down current price ranges, key cost drivers, and smart ways to leverage CountBricks.com to keep your project budget on track.
National snapshot
• Small condo or townhome (up to 1,000 sq ft): \$300 – \$425
• Mid-size single-family home (1,000 – 2,500 sq ft): \$425 – \$650
• Large custom residence (2,500 – 4,000 sq ft): \$650 – \$900
• Luxury estate or multi-system home (4,000 sq ft+): \$900 – \$1,400+
San Diego adjustment
Local labor runs 8-12 % higher than the national average. CountBricks real-time pricing engine automatically applies that factor the moment you request a quote.
1. Home square footage: More ducts equal more labor hours and disposal fees.
2. Number of HVAC zones: Each additional air handler adds 20-25 % to the invoice.
3. Contaminant level: Heavy pet hair, remodel dust, or wildfire ash extends equipment run time.
4. Access complexity: Attic crawl spaces and finished basements increase set-up and takedown costs.
5. Antimicrobial treatments: Post-clean fogging ranges \$0.10-\$0.30 per square foot.
6. Permit and HOA requirements: Some gated communities mandate certified negative-pressure documentation.
Our AI listens to your spoken site notes—“3,100-square-foot split-level, two furnaces, remodel completed last month”—and instantly selects matching material and labor assemblies from our database. The result is a line-item estimate that reflects today’s material index and local wage rates. Explore a demo at CountBricks.com/services.
