How Much Does Air Duct Cleaning Cost in Rockford, IL?
Short answer: for a typical single-family home with one HVAC system, duct cleaning at Clean Air Duct typically runs $350β$500, and $525β$750 for a home with two systems. The number moves with home size, vent count, and how hard the ducts are to reach. The table below is a planning guide, not a price list. The only way to get a real number is an inspection.

What Changes the Price
- Home size and vent count. More vents and longer duct runs mean more work.
- Number of HVAC systems. A home with two furnaces is usually two jobs.
- Access. Tight crawlspaces, finished ceilings, and hard-to-reach trunk lines take longer.
- Condition. Heavy buildup, pests, or renovation debris add time.
- Add-ons. Dryer vent cleaning or sanitizing treatments are priced on top.
Why a Very Low Price Deserves a Question
A full-system cleaning takes real equipment and real time. When an advertised price is far below the going rate, it is fair to ask what it actually covers. Some low prices cover only a few vents. Others are a starting point that grows after the technician arrives. Neither is a good surprise.
Ask this before you book: “Is this the full price for the whole system, including every vent and return, with nothing added on arrival?”
What a Fair Quote Should Include
- A written scope that lists what will be cleaned
- The total price, with any extras clearly separated
- An inspection or walkthrough before work begins
- A walkthrough after the job showing what was done
Commercial and Dryer Vent Pricing
Commercial buildings vary too much for a flat rate, so those jobs are quoted after a walkthrough. See commercial air duct cleaning for what affects those quotes. Dryer vent cleaning is priced separately and depends on vent length, bends, and where the vent exits the home.
Request an estimate and we will explain the scope before any work begins.
Common Questions
Is the estimate free?
That depends on the company. Ask up front whether the estimate or inspection costs anything, and get the answer in writing.
Should I pick the lowest quote?
Compare what each quote covers, not just the number. Two quotes are only comparable if the scope is the same.
Does price change if I have two furnaces?
Usually yes. Each system has its own ductwork, so a two-system home is typically priced higher than a one-system home of the same size.
