People commonly pay between $300 and $1,200 for residential duct cleaning, with averages near $500–$700 depending on home size and system complexity. A duct cleaning cost calculator helps quantify the main price drivers, such as vent count, access, and any required mold remediation or dryer-vent work. This article outlines realistic ranges in USD and drills into how to price a typical duct cleaning job today.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| House size (2,000 sq ft typical) | $250 | $450 | $900 | Assumes standard ducts, no mold |
| Number of supply vents | $3 per vent | $5–$8 per vent | $15 per vent | Labor and materials per vent |
| System type (single furnace, central AC) | $250 | $350–$500 | $700 | Composite pricing by equipment |
| Accessibility (crawlspace/attic) | $150 | $300 | $650 | Hard-to-reach ducts raise cost |
| Add-ons (mold, odor, sanitization) | $50 | $150–$300 | $600 | Higher with remediation |
| Dryer vent cleaning | $75 | $125 | $250 | Separate service, often billed per vent |
| Sanitation or antimicrobial treatment | $0 | $50–$150 | $250 | Optional |
Typical Duct Cleaning Price by Home Size and System Type
Assumptions: Midwest labor rates, standard MERV-8 filtration, asphalt ducts, single-story home with attached garage. Prices reflect standard cleaning rather than mold remediation or extensive repairs. Assumptions: Midwest labor rates, standard materials, normal access.
- Small homes (under 1,000 sq ft) with a single-zone system: $250–$450
- Mid-size homes (1,000–2,000 sq ft) with 6–14 vents: $350–$700
- Large homes (over 2,000 sq ft) or multi-zone systems with access challenges: $600–$1,200
Note: The number of supply vents and return ducts drives a large portion of the final price. Cleaning typically charges per vent plus a base service fee.
| Price Component | Per Unit | Low | Average | High |
|---|---|---|---|---|
| Base service fee | flat | $100 | $180 | $260 |
| Per vent cleaning | per vent | $3–$5 | $5–$8 | $12–$15 |
| Duct smoke/mold remediation | per area | $50 | $150 | $400 |
| Dryer vent cleaning | per vent | $75 | $125 | $250 |
Main Cost Components in a Duct Cleaning Quote
Understanding the quote parts helps compare providers. The primary cost areas are Materials, Labor, and Equipment. Additional items may include Permits, Delivery/Disposal, and Optional Add-ons like sanitation. The table below shows a typical layout for a mid-range job in the U.S.
| Cost Component | Typical Range | Notes |
|---|---|---|
| Materials | $20–$60 | Brushes, sealants, disposable bags |
| Labor | $250–$400 | Technician hours; 2–4 hours common |
| Equipment | $60–$120 | Negative pressure, brushes, access tooling |
| Permits | $0–$100 | Typically not required for residential cleaning |
| Delivery/Disposal | $0–$50 | Waste handling fees |
| Add-ons | $0–$350 | Mold, odor control, sanitization |
| Warranty/Overhead | $20–$60 | Manufacturer or company coverage |
Two key thresholds often move the price. First, vent count: every 6–10 vents add about $30–$60 in typical pricing. Second, access difficulty: crawlspace or attic routes can double labor time, bump up to $300–$600 more in some cases. Regional labor-rate differences can shift totals by 10–25% across states.
- Vent count: 6–10 vents generally $180–$480 extra above base
- Access: easy attic access adds minimal cost; restricted crawlspace may add $150–$350
- System complexity: multi-zone or older ductwork may require more time and materials
- Mold presence: ongoing remediation or antimicrobial treatment adds cost
Smart planning can trim the bill. Focus on scope control, timing, and material choices. Avoid unnecessary upgrades, compare multiple quotes, and bundle services when possible. Pre-cleaning the area, removing bulky obstacles, and scheduling during non-peak seasons can shave 5–15% off the total.
- Limit add-ons to those with clear need
- Request per-vent pricing and verify the number of vents included
- Schedule in off-peak months when discounts may apply
- Ask for a written scope with exact vent counts and areas treated
Regional variations reflect labor markets and costs of living. Coastal states and large metros tend to be higher, while rural areas may be lower. Range adjustments commonly show a 10–25% spread between regions for similar jobs. A midwest city might land near $450 average, while a high-cost coastal market could approach $850.
- West Coast: higher due to labor and material costs
- Midwest: moderate, with regional competition
- South: often competitive pricing, variable by city
- Northeast: tends to be on the higher end due to demand and cost of living
Time is money in quotes. A standard 1,200–2,000 sq ft home with 6–12 vents usually takes 2–4 hours by a crew of 1–2 technicians. Expect hourly rates of $75–$125 per hour per technician, with a base service fee of $100–$180. Large homes or complex duct layouts extend both time and labor costs.
- Typical crew: 1–2 technicians
- Hourly rate: $75–$125 per hour per tech
- Job duration: 2–4 hours common for mid-size homes
Some services increase price significantly. Mold remediation, odor neutralization, sanitizers, or dryer-vent cleaning add-on fees. If ducts show significant mold growth, remediation could push the total well above the standard cleaning range. Sanitation and odor-control services commonly add $50–$150, with higher costs for extensive use of antimicrobial products.
- Mold remediation: $100–$600 depending on area
- Odor neutralization: $50–$150
- Sanitization/antimicrobial treatment: $0–$150
- Dryer vent cleaning: $75–$250
Compare quotes by line item and scope. A solid estimate lists base service, per-vent charges, any add-ons, and social proof like warranty terms. Ensure the quote confirms the number of vents treated, areas cleaned, equipment used, and expected turnaround time. A good estimate shows both total and per-vent pricing to facilitate comparison.
