How much does duct cleaning cost in 2026?
Typical range
$300 – $700
per home (typical)
Professional duct cleaning costs $300–$700 for a typical residential home in 2026. NADCA-certified service running 4–6 hours with truck-mounted equipment runs $450–$700. Beware $99 'duct cleaning specials' that almost universally are upsell traps.
Why the range is wide
Real duct cleaning involves negative-pressure truck-mounted vacuum, agitation tools fed through every supply and return register, full system inspection, and HEPA filtration. The legitimate market price for that work is $300–$700 for a typical 4-bedroom home with 10–15 vents. Sub-$200 specials are loss leaders that exist to upsell into AC tune-ups, mold remediation, or imaginary problems.
Factors that affect price
Number of vents
10 vents (standard 3-bedroom): $300–$500. 15 vents (4-bedroom): $400–$650. 20+ vents (large home): $550–$900.
System type
Single zone: standard pricing. Multi-zone with separate plenums: +20–40%. Commercial systems quote separately.
NADCA certification
NADCA-certified contractors charge premium ($450–$700) but follow industry standards. Non-certified can be cheaper but quality varies wildly.
Add-on services
Sanitizer fog: +$50–$150. Coil cleaning (separate from duct): +$150–$300. Dryer vent cleaning: +$100–$200.
Fraud / bait-and-switch risk
Sub-$100 'whole home duct cleaning' ads almost always upsell on-site, often using fake mold or rodent claims. Stick to NADCA-listed contractors with verifiable reviews.
Regional variation
Pricing is regional but doesn't vary dramatically. Markets with high allergy concerns (Pacific Northwest, Florida) have higher service penetration; markets with lower concerns (interior West) have less competition and slightly higher per-job pricing.
DIY vs pro
DIY vent-register cleaning (vacuum the visible portion, wash the registers) is fine and worth doing twice a year. Real duct cleaning — getting into the trunk lines and branch ducts behind drywall — requires equipment most homeowners don't have. The midpoint: replace your filter on the manufacturer's schedule, vacuum visible registers, and only call for full duct cleaning when there's a documented contamination event (renovation dust, water damage, rodent intrusion).
