How Much to Charge for Air Duct Cleaning
Air duct cleaning typically runs $300–$700 per system for an average home, priced per system or by vent count (around $25–$45 per vent) with a job minimum. System size, number of returns, and access drive the base, and dryer-vent cleaning, sanitizing, and second-system homes are priced as separate lines.
Base pricing
$300–$700 per system for an average home, or $25–$45 per vent with a job minimum. Vent count, system count, and access move the number.
Per system vs. per vent
- Per system — cleanest for a whole-home clean.
- Per vent — suits partial jobs or unusual layouts.
Keep a minimum either way so a small home still covers equipment and travel.
Add-ons that raise the ticket
- Dryer-vent cleaning — its own run and tools; a fire-safety upsell.
- Sanitizing / anti-microbial fog — a separate applied treatment.
- Second HVAC system — essentially a second job, its own line.
Access and contamination
Heavy contamination and hard-to-reach returns add real time. Price difficult access and badly fouled systems above a routine clean rather than absorbing the extra labor.
Frequently asked questions
Per system or per vent?
Per system is cleanest for a whole-home clean; per vent suits partial jobs or unusual layouts. Either way, keep a job minimum so a small home still covers your equipment and time.
Should dryer-vent cleaning be separate?
Yes. The dryer vent is its own run with its own tools and safety value (lint is a fire risk), so it's a natural add-on priced separately from the HVAC duct system.
What raises the base price?
More returns and supply vents, multiple HVAC systems, difficult access, and heavy contamination all add time. A second system in a large home is essentially a second job, priced as its own line.
