Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterResidential Duct Cleaning in Northbrook, IL
Residential duct cleaning in Northbrook, IL typically runs between $299 and $649 for a standard single-family home, depending on the number of duct runs, system age, and what the camera actually finds inside. CleanRun arrives with a written price before any panel comes off, photographs every run before and after, and backs the completed work with a 365-Day Done Right Promise – in writing, not just stated here.
Most Northbrook homeowners who call us have already noticed something: a dusty register face that reappears two days after wiping it, uneven heating between the front of the house and the back bedrooms, or a faint musty smell that only comes from one vent. Those aren’t decorating problems. They’re usually ductwork problems, and a video inspection camera placed inside the plenum – the main distribution box where conditioned air starts its trip through the house – tends to make that clear within the first few minutes of a job.
CleanRun Duct Repair and Cleaning has been doing this since 2013. We’ve completed documented residential cleaning jobs in over 52,000 homes, every one with a written price delivered before work started and a photo record of every duct run delivered when the crew left. If you want to see what that record looks like before committing to anything, call us at (224) 351-9772. A live person answers. Our broader Air Duct Cleaning in Northbrook page covers the full scope of services if you’re still comparing options.
When You Need Residential Duct Cleaning
There’s no universal rule that says ducts must be cleaned every three years. The National Air Duct Cleaners Association publishes general guidance, but the real answer depends on what’s happening inside your specific system. Here are the situations where Northbrook homeowners most commonly need residential duct cleaning – and where a camera inspection makes the case without anyone having to take our word for it.
- Visible dust accumulation at supply registers: If you’re wiping visible grey dust off your register grilles within a week of cleaning them, particulate is settling out of the airstream. That usually means debris has built up far enough inside the duct run to become a continuous source. We’ve pulled the camera back from registers in Northbrook’s older Shermer Road-area ranches and found three inches of compressed lint and drywall dust at the first elbow – exactly the kind of finding a photo record documents for you.
- Uneven airflow between floors or rooms: Northbrook homes with two-story layouts and single HVAC zones frequently develop airflow imbalances as duct interiors collect debris. Partial blockage at a branch takeoff reduces static pressure to the rooms furthest from the air handler, which shows up as temperature differences of four to six degrees between the main level and upper bedrooms during a cold January.
- Post-renovation or construction: Drywall dust is talc-fine and travels through an operating HVAC system during a remodel. Even with registers taped, fine particulate gets in. We regularly clean residential systems in Northbrook’s Techny and Waukegan Road corridor after kitchen and basement finish work – and the before photos consistently show a thin white coating inside every accessible duct run.
- Allergy or asthma symptoms that track with HVAC use: When symptoms worsen specifically during heating or cooling seasons, and improve when windows are open, the airstream is worth looking at. We’re not allergists and won’t diagnose anything – but we can photograph what’s circulating inside the system and let you take that to your doctor.
- Pet dander accumulation: A single large-breed dog can shed enough dander in one Northbrook winter to create a measurable layer of particulate on the walls of flex duct within eighteen months. Homes with two or more pets typically show visible accumulation at the first branch off the plenum within twelve to eighteen months of the last cleaning.
- Moving into a home you didn’t build or own previously: This one gets overlooked. If you bought a home in Northbrook’s Indian Hill, Clover Hill, or Walters Avenue neighborhoods in the last five years, you have no documented record of when the ducts were last cleaned or what’s inside them. A camera inspection costs nothing to schedule and produces a before photo you can actually look at.
Our Residential Duct Cleaning Process
The process CleanRun uses isn’t proprietary – it follows NADCA ACR standards and relies on equipment from Rotobrush and Abatement Technologies, brands you can look up independently. What makes it different from a $79 coupon job is documentation at every step and a written scope that doesn’t change after we arrive.
- Written price before any work starts (Haven Standard Clause 1): Before a single register cover is removed, your technician – uniformed, background-checked, and identified by name before arrival under Haven Standard Clause 3 – delivers a written price that covers the full scope of the job. That price doesn’t change unless you ask us to do additional work. “Call for a quote” doesn’t exist at CleanRun. The number is on paper before work begins.
- Pre-cleaning camera inspection and documentation: We insert a flexible borescope camera into the plenum and into each accessible duct run before we touch anything with a brush or vacuum. Every run is photographed. You receive those photos as part of your standard job record. In Northbrook homes with original 1960s and 1970s sheet-metal ductwork – common in the Greenbrook and St. Norbert areas – the before photos often show debris levels that a quick vacuum pass would never have addressed.
- Negative-pressure extraction setup: Negative-pressure extraction means we connect a HEPA-filtered collection unit to the main trunk line and create a controlled vacuum inside the duct system before agitation begins. Air – and everything in it – moves toward the collection unit, not back into your home. The Nikro and Abatement Technologies units we use are rated for residential systems and are HEPA-filtered at the exhaust, so no extracted particulate re-enters the living space during the process.
- Mechanical agitation of every duct run: With negative pressure established, a Rotobrush rotary brush system works through each supply and return duct run, breaking up adhered debris from the duct walls. This is the step that separates a documented cleaning from a shop-vac visit. The rotary brush contacts the interior surface. The vacuum pulls the dislodged material to the collection unit. We work every accessible run – not just the ones visible from the main level.
- Register and grille cleaning, blower compartment inspection: Every supply and return register grille is removed, cleaned, and reinstalled. The blower compartment and air handler cabinet are inspected and photographed. If the evaporator coil shows visible contamination that would affect airflow or indoor air quality, we document it and tell you before recommending anything. Honeywell and Aprilaire filtration components, if present in your system, are checked and noted in the job record.
- Post-cleaning camera documentation and job record delivery: After agitation and extraction are complete, the camera goes back in – same runs, same angles. You get a before-and-after photo set for every duct run, a written summary of what was found, and a copy of your 365-Day Done Right Promise in writing. The job record is yours to keep, share with a home inspector, or use as documentation if you ever sell the property.
BeforeAfterResidential Duct Cleaning Pricing in Northbrook
Residential duct cleaning in Northbrook runs $299 to $649 for most single-family homes. That range is real, not a floor designed to climb once we’re in the door. Here’s what moves the number.
| Home Type / Scope | Typical Price Range |
|---|---|
| Condo or townhome (8-12 runs) | $299 – $389 |
| Single-family home, standard (13-20 runs) | $389 – $499 |
| Larger home or two-system house (21+ runs) | $499 – $649 |
| Camera inspection only (pre-purchase or diagnostic) | $99 – $149 |
| Add-on: dryer vent cleaning at same visit | $89 – $129 |
What affects cost in Northbrook specifically:
- Duct count and linear footage – a sprawling 1970s ranch on Techny Road with 24 supply and return runs costs more to clean than a two-story townhome with 11.
- Duct material – original galvanized sheet metal holds debris differently than modern flex duct, and the agitation approach adjusts accordingly.
- Debris load – if the before photos show heavy contamination, the cleaning takes longer. The written price reflects that before work starts, not after.
- System accessibility – finished basements with enclosed duct chases require additional access cuts, which are quoted in advance and restored before the crew leaves.
- Add-on services – sanitizing with an EPA-registered product, dryer vent cleaning, or air handler coil treatment are quoted as separate line items so you can decide on each one independently.

FAQs – Residential Duct Cleaning in Northbrook
How much does residential duct cleaning cost in Northbrook, IL?
Residential duct cleaning in Northbrook typically costs between $299 and $649, depending on the number of duct runs, system configuration, and debris load found during the pre-cleaning camera inspection. A standard single-family home with 13 to 20 supply and return runs generally falls in the $389 to $499 range. CleanRun delivers a written price before any work starts – no exceptions. Call (224) 351-9772 for a written estimate delivered before we touch anything.
How long does a residential duct cleaning take?
Most Northbrook residential duct cleaning jobs take two to three hours for a standard home with one HVAC system. Larger homes with two systems, or homes with heavy debris accumulation documented in the before-camera footage, can run three to four hours. The technician gives you a realistic time estimate based on the written scope before starting. We don’t rush the camera pass or the mechanical agitation to hit a schedule – both steps have to be complete for the after photos to show a difference worth documenting.
Is residential duct cleaning actually necessary, or is it a sales tactic?
It depends on what the camera shows. CleanRun’s position is straightforward: if the before photos don’t show meaningful debris accumulation, we’ll tell you that and document it in writing. Northbrook homes that have been cleaned within the last four to five years, have no pets, haven’t been through a renovation, and use quality filtration regularly may not need cleaning yet. We’d rather show you a camera image that says “not yet” than sell you a job that doesn’t change anything. The inspection is what guides the recommendation – not a sales script.
What’s the difference between residential duct cleaning and a standard air duct cleaning?
Residential duct cleaning refers specifically to cleaning the forced-air distribution system in a home – supply runs, return runs, the plenum, registers, and the blower compartment of the air handler. It’s distinct from commercial duct cleaning, which involves different system types, larger trunks, and regulatory documentation requirements. When you see “air duct cleaning” on our home page, residential duct cleaning is the core service that phrase describes for homeowners. The process, equipment, and documentation standard are the same regardless of what you call it: camera inspection, written price, mechanical agitation under negative pressure, and a before-and-after photo record for every run.
Why Northbrook Homeowners Work with CleanRun
Northbrook’s housing stock is layered – 1950s and 1960s brick ranches in the Greenbrook area, 1970s and 1980s colonials near Sunset Ridge, newer construction in the developments off Pfingsten Road. Each decade of construction brought its own duct design, and each one ages differently. The galvanized sheet-metal trunk lines in a 1965 Northbrook ranch accumulate debris differently than the flex duct in a 2005 build, and a technician who’s been inside both – with a camera, not just a hose – knows the difference on arrival.
CleanRun has been documenting residential duct jobs in the Chicago North Shore corridor since 2013. Tomas Reyes built the company around one principle that the rest of the industry avoids: show the customer exactly what’s there before asking them to spend anything. The before photo isn’t a sales tool. It’s a record. The after photo is the proof that the work happened. The 365-Day Done Right Promise means that if something wasn’t done right, it gets made right – in writing, without a call to a manager.
If you want to compare that to a competitor’s written estimate, bring it. The Free Second Opinion is available at no cost, and CleanRun’s number goes next to theirs on paper before you decide. That’s Haven Standard Clause 1 applied to competitive pricing, not just to our own jobs.
Call (224) 351-9772 to schedule your written estimate or to ask what a before-camera inspection would show in your home. A live person answers every call. There’s no voicemail queue, no callback promise – just a direct conversation about what you’re seeing and what it might mean.
