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.

AfterVideo Inspection in Northbrook, IL
Duct video inspection is a camera-based diagnostic service where a flexible, high-resolution camera travels through your duct runs – the individual branches of sheet metal or flex duct that carry conditioned air from your furnace or air handler to each room – and records exactly what is inside. In Northbrook, a standard residential inspection covers the supply trunk, return plenum, and accessible branch runs, and takes roughly 60 to 90 minutes. The result is a documented record of actual conditions, not a technician’s verbal summary.
Most homeowners in Northbrook who contact us for Air Duct Cleaning in Northbrook start here, because the camera tells both of us what we are dealing with before anyone quotes a scope of work. That is how Haven Standard Clause 1 works in practice: a written price cannot be honest unless it is based on verified conditions. If you want to schedule a video inspection or have questions before booking, call us at (224) 351-9772 – a live person answers every call.
Tomas Reyes started CleanRun in 2013 with a straightforward premise: customers should be able to see what is inside their ducts before agreeing to pay for cleaning. We have held that standard on every job since – more than 52,000 homes served, every one of them documented with a photo and camera record before and after the crew left.
When You Need Video Inspection
Some situations make a camera inspection the obvious first step. Others are less obvious but equally important. Here is what we see most often in Northbrook:
- You bought the home between 2015 and 2025 and have no service history. A large share of Northbrook’s housing stock in neighborhoods like Shermer Road Estates and the streets east of Waukegan Road was built in the 1970s and 1980s with galvanized steel ductwork that has never been internally inspected. A camera confirms whether you have intact lining, debris accumulation, or early corrosion – before you commit to anything.
- Uneven room temperatures that HVAC adjustments haven’t fixed. When one room runs noticeably warmer or cooler than the thermostat target, the cause is often a partial blockage or a disconnected duct run – both of which a camera locates in minutes. Guessing without visual confirmation wastes time and money.
- Musty or mildew-like odor that returns after filter changes. Northbrook sits close enough to the North Shore’s drainage patterns that basement mechanical rooms can pull humidity into return plenums. A camera inspection locates the moisture source and any microbial growth so remediation targets the right section of duct.
- Recent rodent activity or signs of pest intrusion. We find nesting material, droppings, and entry gaps in ducts more often than homeowners expect – particularly in older homes with crawlspace or basement ductwork near the foundation. The camera locates every affected run so the cleaning scope is precise, not approximate.
- Post-renovation dust that persists weeks after construction is complete. Drywall compound, fiberglass particulate, and construction dust migrate into supply registers during renovation work. Video inspection confirms how far the material traveled and whether it reached the air handler or filter housing.
- You received a duct cleaning quote and want a second opinion on the scope. CleanRun offers a free second opinion on any written estimate. A camera inspection is how we put a verifiable number next to a competitor’s claim – the footage either supports their scope or it does not.
Our Video Inspection Process
Every inspection follows the same documented sequence. Nothing is skipped to save time, and the camera footage is part of the deliverable you receive when we leave.
- Written price before any panel comes off. Before we open a single access point, you receive a written price for the inspection under Haven Standard Clause 1. The price does not change based on what the camera finds; if the findings require a different scope of work, that is a separate written quote.
- System map and access point identification. We trace your duct layout from the air handler through the supply trunk and into each branch run, noting register locations, duct material (sheet metal, flex duct, or duct board), and any existing access panels. In Northbrook homes with finished basements, this step confirms which runs are reachable without drywall cuts.
- Camera insertion and documented sweep. Our camera – a flexible inspection unit with LED illumination – enters through the register or an existing clean-out port and travels the full length of each accessible run. We record continuous footage, not spot photographs, so the full interior condition is documented. The camera resolution is sufficient to identify debris type, liner condition, and joint separations.
- Plenum and return-side documentation. The return plenum (the large chamber that draws room air back to the furnace) is inspected separately. This is where Northbrook homes with older fiberglass-lined plenums often show liner deterioration – the fiberglass fragments and releases into the airstream. The camera catches it; a visual-only inspection frequently misses it.
- Findings review with the homeowner, footage included. We walk through the footage with you on-site. You see the debris location, the measurement at the worst accumulation point, any joint gaps or liner damage, and any moisture staining. We describe what we found in plain terms: “the camera showed a 2-inch debris layer at the first elbow off the trunk, and a 4-inch section of separated flex duct in the northeast bedroom run” – not a general assessment.
- Written scope and photo record delivered. The inspection closes with a written summary of findings, a recommended scope of work with a written price, and the camera footage as part of your documented record. The 365-Day Done Right Promise is attached to every subsequent job that starts from this inspection.
BeforeAfterVideo Inspection Pricing in Northbrook
Duct video inspection in Northbrook typically ranges from $95 to $195 for a standard single-system residential inspection. Here is what moves the number:
- $95 – $130: Single-story home, one HVAC system, accessible ductwork in an unfinished basement or utility room. Straightforward layout with no flex-duct runs longer than 20 feet.
- $130 – $165: Two-story home or a single-story with a partially finished basement. Multiple return drops, some runs requiring access through finished wall registers. Common in Northbrook’s Techny Road and Meadowbrook neighborhoods.
- $165 – $195: Two-system homes (separate HVAC units for upper and lower floors), homes with dual-trunk layouts, or properties with documented prior pest activity requiring careful access management. Older Northbrook homes near the forest preserve corridors often fall here.
If CleanRun performs the air duct cleaning near me in Northbrook, IL based on the inspection findings, the inspection fee is applied toward the cleaning total. That is standard, not a conditional offer. The written price you receive before work starts reflects the credit already built in.
A note on free estimates: the estimate for any subsequent cleaning or repair work is free. The inspection itself has the fee structure above because it is a documented technical service – footage, written findings, and a scope recommendation are tangible deliverables, not a sales visit. If you have a written quote from another company and want us to review it, call (224) 351-9772 – the second opinion is free, and we put our number in writing next to theirs.
What the Camera Actually Finds in Northbrook Ductwork
This is where generic content fails homeowners and where documented inspection earns its cost. Northbrook’s housing stock has specific patterns we have catalogued across hundreds of inspections since 2013.
Homes built in the 1970s and early 1980s in areas like Greenbrook and the blocks north of Dundee Road frequently have original fiberglass duct liner – a blanket-like insulation bonded to the interior of sheet metal ducts. Over 40-plus years, that liner deteriorates. The camera shows it as a textured, flaking interior surface rather than a smooth metal or clean-flex interior. Deteriorated liner releases glass microfibers into the supply airstream. That is not a theoretical risk; the footage makes it visible.
Homes built in the late 1990s through the 2010s in Northbrook’s newer subdivisions near Sanders Road more commonly use flexible duct – corrugated plastic tubing encased in insulation. Flex duct runs that were installed with insufficient support sag between joists, creating low points where condensate and fine debris accumulate. The camera shows a pooled debris column at each sag point. Abatement Technologies extraction equipment reaches these points with purpose-built flex-duct tools; a standard shop vacuum does not.
Post-renovation inspections in Northbrook routinely find drywall compound and fiberglass insulation particulate in supply runs that were left open during construction. We have found it as far as 30 feet from the nearest open register, carried by supply air pressure during the heating season. The camera locates the extent so cleaning starts and stops at the right points.
How Video Inspection Connects to Cleaning
The inspection and the cleaning are separate services with separate written prices. This is intentional. A camera inspection is diagnostic; an Air Duct Cleaning job is remediation. Combining them into a single package before the camera has run means the scope is estimated, not verified – and an estimated scope is how $79 coupon companies end up charging three times that amount at the point of service.
When the inspection confirms cleaning is warranted, we quote a commercial duct cleaning scope based on what the footage documented: which runs need mechanical agitation (Rotobrush rotary brush systems for sheet metal runs), which sections need negative-pressure extraction (Nikro or Abatement Technologies equipment pulling air through the system under negative pressure – essentially a controlled vacuum that prevents dislodged debris from re-entering living spaces), and whether the air handler and plenum need separate attention.
The written cleaning quote references the inspection footage by run and section. You are not approving a general service; you are approving work on documented conditions in specific locations.
FAQs – Video Inspection
How long does a duct video inspection take in a typical Northbrook home?
A standard single-system inspection in a Northbrook home takes 60 to 90 minutes from camera insertion to findings review. Two-system homes or properties with complex layouts – split-level construction, dual-trunk systems, or runs that require access through multiple registers – run 90 to 120 minutes. We do not schedule inspections back-to-back; the time block is reserved for documentation, not just camera movement. If your home is in the Shermer Road or Techny Road area and you want a precise time estimate before booking, call (224) 351-9772 and we can give you a range based on your system description.
Can I watch the camera footage during the inspection?
Yes, and we expect you to. The technician carries a display that shows the live feed, and we walk through the footage together before writing any scope recommendation. This is not a courtesy; it is the whole point. You should be able to see the debris layer, the liner condition, and any gaps or separations before anyone discusses what comes next. The recorded footage is included in your written job record when we leave.
Is video inspection necessary if my ducts were cleaned a few years ago?
It depends on what documentation came with that cleaning. If you have a photo record showing the interior of your duct runs before and after the prior cleaning, the footage tells us the starting point for current conditions. If you received a verbal confirmation or a generic invoice without footage, the prior cleaning is unverifiable – and in Northbrook homes where we have followed other companies, we have found systems described as clean that still carried substantial debris in branch runs and at elbows. A camera inspection is the only way to confirm actual current conditions rather than assumed ones.
What happens if the camera finds something that needs repair, not just cleaning?
The camera footage becomes the basis for a written repair scope, separate from any cleaning quote. Common findings in Northbrook homes include joint separations where sections of sheet metal have pulled apart at the seam (losing conditioned air into the attic or basement before it reaches the register), collapsed flex duct sections, and corroded fittings at register boots. Each issue is documented by run and location in the footage. The written repair quote references the footage so you know exactly what is being fixed and where. CleanRun handles both duct repair and cleaning, so the scope can be addressed in one visit if the findings warrant it – but you receive separate written prices for each scope of work, not a combined number you cannot parse.
