What Changes the Price
What Affects the Cost of Air Duct Cleaning?
Two homes of the same size can get different quotes. These are the main reasons.
Number of HVAC systems
A home with two independent systems means more ductwork and more work than a one-system home.
Home size
Larger homes generally have longer duct runs and more registers to clean.
Number and layout of vents
More supply and return vents, and longer or more complex runs, take more time.
Accessibility
Ducts in tight attics, crawlspaces or hard-to-reach areas can add time to the job.
Condition of the ducts
Heavy buildup takes more work to remove than a light layer of dust.
Scope of the job
Dryer vent cleaning is a separate service. See our dryer vent cleaning page.

What You Are Paying For
What Is Included in a Full-System Cleaning
A full residential cleaning covers the whole duct system, not just the vents you can see.
- Cleaning of all supply vents and return ducts
- Cleaning of the blower compartment, including the blower wheel, and inspection of the evaporator coil when accessible
- A truck-mounted 12,000 CFM vacuum pulling debris out of the system
- Two technicians, typically 3 to 5 hours for a single-furnace home
- Before-and-after photos reviewed with you at the end of the job
See the full six-step process on our residential air duct cleaning page. Prices above do not include dryer vent cleaning, which is a separate service.
Comparing Quotes
How to Compare Air Duct Cleaning Quotes
Two quotes can look very different because the work is not always the same. Before you compare numbers, ask each company:
- How many HVAC systems does the price cover?
- Are all supply vents and return ducts cleaned, or only the main lines?
- Is the blower compartment included?
- Are there extra charges for additional vents, extra floors, or larger homes?
- What is the full price once the technician has seen the system?
- What equipment is used, and what is photographed or documented?
Market context. Published prices vary a lot, mostly because of scope. As of October 2026, one Rockford-area company advertises a starting price of $199 for homes up to 2,000 sq ft with one furnace and adds charges for larger homes and extra floors, while another lists $599 for up to 15 ducts plus $15 per additional duct. National guides such as Angi report an average of about $389, with most jobs between $271 and $509. These figures are not Clean Air Duct prices and cover different scopes, so compare what is included rather than the headline number.
