The Bottom Line
Whole-Home Duct Cleaning Typically Runs $450–$1,000+
If you're researching air duct cleaning cost in Central Illinois, the honest answer is that most whole-home jobs land somewhere between $450 and $1,000. The exact number depends on how many vents you have, how many HVAC systems serve the house, and whether the quote includes the main trunk lines and furnace.
We won't throw a number at you without those details. What we will do is give you a free, written estimate with the scope spelled out — and that estimate is the price you pay. No upsells on the driveway.

What Affects Your Quote
Six Things That Change Your Duct Cleaning Price
01
Number of vents
Supply and return count is the biggest driver. A 12-vent ranch is a different job than a 28-vent two-story with basement returns.
02
Number of HVAC systems
Two furnaces means two blower compartments, two return drops, and twice the trunk line. It also means twice the labor.
03
Trunk lines included?
Some quotes only cover the vent openings you can see. Cleaning the main trunk lines and return drop is where the real debris lives.
04
Equipment type
Truck-mounted vacuums pull far more air than portable units. That extraction power is part of what you're paying for.
05
Access difficulty
Tight crawlspaces, sealed basements, attic ductwork, and rooftop dryer vents add time and sometimes specialized tools.
06
Condition of the system
Post-construction dust, heavy pet hair, years of neglect, or prior water damage can add significant cleaning time.
Common Add-Ons & Related Services
| Service | Typical Range | Notes |
|---|---|---|
| Dryer vent cleaning | $75 – $175 | Depends on length and termination point. |
| Furnace/blower cleaning | Included in full-system quote | Priced as part of the complete clean, not a hidden add-on. |
| Second HVAC system | $250 – $450 | Added to the base whole-home price. |
| Sanitizer / deodorizer | $50 – $150 | Optional treatment. |
Watch Out For The $49 "Whole House" Coupon
No company can dispatch a truck, two trained technicians, and truck-mounted equipment for several hours at $49. Those ads get a foot in the door, then upsell extra vents, "mold treatment," sanitizer, and trunk-line cleaning once the crew is in your basement. The final bill often exceeds a fair upfront quote.
At Bennett, the price we write down is the price you pay. If a competitor gives you a lower written quote for the same scope, we'll beat it by 10%.
Why Truck-Mounted Costs More — And Is Worth It
Portable Units Can't Pull What A Truck Can
Our truck-mounted systems pull far more air than the portable units most coupon cleaners bring into your home. That power matters because it actually removes debris from the ductwork instead of stirring it around.
We also put the entire system under negative pressure before we open anything, so dust and allergens exit through the truck hose instead of escaping into your living space. That's the difference between a cleaning that looks good and one that actually improves your air.
What You're Paying For
- Truck-mounted vacuum extraction
- Negative-pressure containment so dust stays contained
- All supply vents, return vents, and main trunk lines
- Furnace cabinet, blower compartment, and return drop
- Written quote before work starts — no hidden add-ons
Pricing FAQs
Common Questions About Duct Cleaning Costs
How much does air duct cleaning cost in Central Illinois?
+
Most whole-home duct cleanings in Peoria, Bloomington-Normal, Champaign-Urbana, Springfield, and Decatur fall between $450 and $1,000. A small ranch with one system and 10–14 vents is usually on the lower end; a large two-story home with 25+ vents or two HVAC systems is on the higher end. Dryer vent cleaning is typically a separate, lower flat fee.
Why is there such a wide price range?
+
The number of supply and return vents, the number of furnaces, whether the main trunk lines are included, how accessible everything is, and the type of equipment used all change the time and labor. A coupon company that quotes $49 is not doing the same job as a truck-mounted crew that spends 2–4 hours in your home.
What does a whole-home duct cleaning include?
+
At Bennett, a full residential clean includes all accessible supply vents, return vents, the main trunk lines, the return drop, and the furnace cabinet and blower compartment. We put the system under negative pressure so debris leaves the house instead of circulating inside it. We show you what came out before we close up.
Is furnace cleaning included, or extra?
+
Furnace cleaning is part of how we quote a complete system clean. We don't treat the blower wheel and burner compartment as a surprise add-on. When you call, we'll talk through the specs of your system with you and give you one written number that covers everything we discussed.
How much does dryer vent cleaning cost?
+
Dryer vent cleaning is typically the least expensive service we offer. A straightforward first-floor through-the-wall vent is at the low end; long runs, rooftop terminations, or multi-story vertical vents cost more because they take longer and need specialized tools.
Do you charge for estimates?
+
No. Estimates are always free, in writing, and there's no obligation. Call (309) 472-5036 and we'll talk through the specs of your system with you, then give you an honest price up front.
How do I know I'm getting a fair duct cleaning price?
+
Get the scope in writing: vent count, trunk lines, furnace components, equipment type, and total price. Ask whether the crew uses truck-mounted extraction. If the price is far below the market range, expect upsells. A fair quote doesn't change once the truck is in your driveway.
How often should ducts be cleaned?
+
Every 3 to 5 years for most Central Illinois homes. Go sooner after remodeling, if you have pets that shed heavily, or if someone in the home has allergies or asthma. Anyone pushing annual cleanings for every household is selling, not advising.

What People Ask Dave About Price
Dave, what would my house actually cost?
+
Without those details — the vent count, how many HVAC systems, and whether the dryer vent is included — I can only give you a range, and the honest range for Central Illinois is $450–$1,000 for a whole home. Use the estimator above for a closer number, or call (309) 472-5036 and we'll price your exact system in a couple of minutes.
Why is your price higher than the coupon company down the road?
+
Because it's a different job. Truck-mounted extraction, negative-pressure containment, every return and trunk line, the furnace cabinet and blower, and a crew that's usually in the house 2–4 hours. The coupon price covers a shop vac on a handful of supply vents, and the rest gets added once they're inside.
Are there any add-on charges once you arrive?
+
No. The written quote is the price. If we open the system and find something we didn't discuss on the phone — a second furnace nobody mentioned, an inaccessible run — we stop and talk to you before doing anything that changes the number.
Do you price-match other duct cleaning quotes?
+
Yes. Bring us a comparable written quote from a licensed competitor and we'll beat it by 10%. Just make sure you're comparing the same scope — vent count, trunk lines, furnace components, and equipment type. Call (309) 472-5036.
Is duct cleaning worth the money?
+
If your ducts are genuinely dirty — construction debris, heavy pet dander, years of buildup, a house you just bought — yes, and you'll see it in the collection bin. If you had it done two years ago and nothing has changed, save your money. I'd rather tell you to wait than sell you a cleaning you don't need.
