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.

AfterFull System Cleaning in Naperville, IL
Full system cleaning is a complete cleaning of your entire forced-air HVAC system: every supply duct run, every return run, the main supply and return plenums, the air handler cabinet, the blower assembly, and each register grille. In Naperville, most homes built between 1990 and 2015 go 10 or more years between cleanings, long enough for a measurable layer of debris to settle into every horizontal duct run. A single-register “spot clean” won’t touch that. A full system cleaning does.
This page covers exactly what the service includes, what it costs in Naperville’s market, and what you’ll have in hand when we leave. If you’d like to start with the broader picture of how we approach duct work, our Air Duct Cleaning in Naperville page covers the full service category. Or call us directly at (331) 236-5490 – a live person answers every call, and a written price is ready before any work starts.
CleanRun Duct Repair & Cleaning has documented the inside of duct systems in Naperville homes since 2013. Every full system cleaning concludes with a photo record of every duct run – before and after – delivered to you as a standard job record, not an optional add-on. That’s what separates a documented cleaning from vacuum noise.
When You Need Full System Cleaning
There are clear, observable signals that a home’s HVAC system needs the full treatment rather than a partial service. Here’s what we see regularly in Naperville homes:
- It’s been more than 8-10 years since the last full cleaning. Naperville’s older neighborhoods – Hobson West, Cress Creek, and much of the area platted in the 1980s and 1990s – have duct systems that predate modern sealed construction. Older flex duct and fiberglass-lined rigid duct accumulate debris faster than newer systems, and the contamination tends to be layered rather than loose.
- You’re seeing fine dust on register faces within days of cleaning. When dust reappears that quickly, the source is upstream – inside the duct run, not on the surface. A camera inspection at the first elbow typically shows a packed debris shelf. That can’t be wiped off; it has to be mechanically dislodged and extracted under negative pressure.
- You recently completed a renovation, drywall work, or addition. Drywall dust – calcium sulfate, paper fiber, and silica – is extremely fine and migrates through the entire duct system. We photographed a home on Bauer Road in Naperville after a kitchen gut-and-rebuild where the main supply plenum held nearly two inches of compacted drywall dust that had bypassed the filter entirely during construction.
- You have a new allergy or respiratory diagnosis in the household. We’re not physicians, and we won’t claim that a duct cleaning cures anything. But when a pediatrician or allergist recommends reducing airborne particulates, documenting the current state of the duct system is a useful and measurable first step.
- Your HVAC equipment is running longer cycles than it used to. Debris accumulation at the blower wheel or evaporator coil face forces the system to work harder to move the same volume of air. A full system cleaning that includes the air handler cabinet – not just the duct runs – addresses that directly.
- You bought the home recently and have no service records. In Naperville’s resale market, it’s common to receive a home inspection report with no mention of duct condition. A pre-move-in full system cleaning with a documented photo record gives you a verified baseline. You know exactly what you started with.
Our Full System Cleaning Process
Each step below is part of the H.A.V.E.N. Standard – the operational framework every CleanRun technician follows on every job. The sequence matters: there’s no benefit to cleaning a duct run if the blower is going to push debris back through it an hour later.
- Pre-job inspection and written scope delivery. Before a panel comes off, we walk the system. We document the duct layout, identify flex-duct sections, note the equipment age and filter configuration, and log the number of supply and return runs. You receive a written price for the full scope at this point – Haven Standard Clause 1. That price doesn’t change when we’re done unless you’ve asked us to add something.
- Pre-cleaning camera documentation of every duct run. A camera goes into every run before we touch it. This takes time. We do it anyway, because the before photo is what makes the after photo meaningful. Without it, you’re taking our word for what was in there. A 3-inch debris shelf at the first elbow is a documented fact when it’s on camera. The photo record is yours at the end of the job.
- Negative-pressure establishment at the air handler. We connect our extraction unit directly to the main trunk line adjacent to the air handler, pulling the system into negative pressure (below atmospheric) before any mechanical agitation begins. This is the step that separates professional extraction from a shop vac. Negative-pressure extraction means that when debris is dislodged, it moves toward the collection unit rather than back into the living space. We use Nikro extraction equipment rated for commercial and residential duct systems.
- Mechanical agitation through each supply and return run. With the system under negative pressure, we work each duct run individually with a rotary brush system – Rotobrush equipment, specifically – sized to the duct diameter. For 4-inch flex runs common in Naperville split-level homes, the brush diameter matches the duct interior. For 10-inch or 12-inch rigid trunk lines, we size up accordingly. Each run gets the brush from the register opening back to the trunk. Debris that was packed against the duct wall gets mechanically broken up and pulled to the extraction point.
- Air handler cabinet, blower compartment, and plenum cleaning. The plenum is the main distribution box that connects your air handler to the duct tree – supply plenum on the high-pressure side, return plenum drawing air back to the unit. Both collect debris in ways that individual duct runs don’t. We clean both plenums, the interior of the air handler cabinet, and the blower wheel housing. If the evaporator coil face is accessible and shows debris buildup, we document it and discuss it with you before touching it.
- Post-cleaning camera verification and photo record delivery. Every duct run that was photographed before cleaning is photographed again after. You receive the complete before-and-after record. If any run doesn’t meet the standard, we go back in. That’s the 365-Day Done Right Promise in practice: if it’s not right, we make it right – in writing, not subject to a manager call.
BeforeAfterFull System Cleaning Pricing in Naperville
Full system cleaning in Naperville typically runs between $349 and $699 for a standard single-family home. That range covers the majority of homes in Naperville’s primary residential areas – Brookdale, Wheatland, Waubonsie Valley, and comparable neighborhoods – with 10 to 22 supply and return runs and a standard forced-air system.
The written price you receive before work starts accounts for the specific variables in your home. Here’s how the range breaks down:
- Number of duct runs (supply + return): This is the single largest factor. A 1,400-square-foot ranch with 10 runs costs less to clean than a 3,200-square-foot two-story with 24 runs. We count the runs during the pre-job walkthrough, and that count is in the written price.
- Duct type and condition: Flexible duct – the corrugated silver hose common in Naperville homes built between 1985 and 2005 – is more labor-intensive to clean than smooth rigid sheet metal because the inner liner accordion folds trap debris. Heavily contaminated flex duct with interior liner damage may be a candidate for replacement rather than cleaning; we’ll document what we find and tell you both options and both prices.
- Air handler cabinet access and blower condition: If the blower wheel is caked with debris and requires removal to clean properly, that adds time. If the cabinet is in a finished mechanical room with restricted access – common in Naperville’s finished-basement homes – that affects labor as well. Both are line items in the written scope, not surprises.
- System configuration: Homes with dual-zone systems or two separate HVAC units – increasingly common in Naperville new construction from 2010 onward – require two full cleaning passes. That’s priced as two systems, clearly stated before work starts.
What’s always included at no additional charge: pre-cleaning camera documentation of every run, the written price before work starts, the post-cleaning photo record, and the 365-Day Done Right Promise. These aren’t upgrades. They’re the standard.
We also offer a free second opinion on any written estimate. If you’ve received a price from another Naperville duct cleaning company, bring it. We’ll put our number next to it in writing, and you can compare both – line by line – before making a decision.
Call (331) 236-5490 to schedule a written estimate. There’s no “call for a rough range” here – that’s not how we operate. You’ll get a specific number for your specific home before we start.
FAQs – Full System Cleaning
How long does a full system cleaning take in a typical Naperville home?
A full system cleaning in a standard Naperville single-family home – between 10 and 22 runs, single system – typically takes 3 to 5 hours. Larger homes in Naperville’s newer northwest developments, where 26 or more runs are common, can run 5 to 7 hours. The camera documentation at the start and end adds time that a shop-vac crew skips; we don’t skip it. An accurate time estimate for your specific home is part of the written scope you receive before work begins. Call (331) 236-5490 and we can give you a realistic window based on your square footage and system layout.
Is a full system cleaning different from a “standard duct cleaning”?
Air Duct Cleaning services like our full system cleaning cover every component of the forced-air HVAC system: all supply duct runs, all return runs, both plenums, the air handler cabinet, and the blower housing. A “standard duct cleaning” at a discounted price – the $79-coupon variety common in Naperville and DuPage County broadly – typically means a technician vacuums the register openings and a few accessible duct sections without establishing negative pressure at the trunk line or cleaning the air handler cabinet. The difference shows up in the before-and-after photos. If a company can’t show you camera documentation of every run, ask why. Call (331) 236-5490 if you want to see what a documented cleaning record actually looks like.
How do I know the cleaning was actually done – and done completely?
The photo record is how you know. Every duct run is photographed before we touch it and again after we finish it. That record is delivered to you as a standard part of the job – a documented before-and-after for every run in the system. If a run isn’t clean when we photograph it the second time, we go back in. That’s what the 365-Day Done Right Promise is: written accountability, not a verbal assurance. If you’ve had a duct cleaning before and received nothing in writing and no photos afterward, you have no way to verify what was done. We think you should be able to verify it. Call (331) 236-5490 and we’ll walk you through what the job record looks like before you book anything.
Should I replace my filter before or after the full system cleaning?
After – always. Installing a fresh filter before cleaning means it will be loaded with the debris we dislodge during extraction. Install the new filter once the cleaning is complete and the system has been run for a short cycle to clear any residual fine particulates. If your system uses a higher-efficiency filter – a Honeywell or Aprilaire media filter rated MERV 11 or above – we’d recommend keeping a replacement on hand for the same day. We’ll note the filter configuration during the pre-job walkthrough and flag it in the written scope if a same-day change is advisable. For any questions on filter type or sizing before your cleaning date, call (331) 236-5490.
CleanRun Full System Cleaning: What You Have When We Leave
When a CleanRun technician finishes a full system cleaning at a Naperville home, you have four concrete deliverables: a clean system verified by camera, a before-and-after photo record of every duct run, a copy of the written price you were given before work started, and the 365-Day Done Right Promise backed in writing. If anything isn’t right within 365 days, we come back. That’s not subject to a manager call or a service fee – it’s written into every job.
Every technician operating under the H.A.V.E.N. Standard is background-checked, uniformed, and identified by name before they arrive at your home (Haven Standard Clause 3: Verified Crews). The equipment on the truck – Rotobrush brush systems and Nikro extraction units – is the same professional-grade equipment used in commercial duct cleaning. You can look up both brands independently before agreeing to anything.
Since 2013, CleanRun has served more than 52,000 homes with a written price before work started and a documented photo record when the crew left. That practice started on the first job and hasn’t changed.
If you’re in Naperville and want a written price for a full system cleaning – not a rough range, an actual number for your home – call (331) 236-5490. A live person answers. The estimate is free. The price is in writing before anything else happens.
