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 The Woodlands, TX
Full system cleaning is a complete, source-removal cleaning of every component in your home’s forced-air system: supply ducts, return ducts, the air handler, blower assembly, evaporator coil housing, and every register and grille. In The Woodlands, where homes built between 2000 and 2022 commonly run 3,000 to 4,500 square feet with two or three air handlers and 20-plus duct runs per system, a partial cleaning leaves enough debris behind to recontaminate the sections you just cleaned within a single season. A full system clean addresses the whole circuit at once, documented in photographs from every run, with a written price in hand before any panel comes off.
If you’ve landed here after reading about our Air Duct Cleaning in The Woodlands services and want to know exactly what a top-to-bottom cleaning involves, this page covers the process, the pricing range, and what distinguishes real source-removal work from the shop-vac-and-blow visits that dominate the $79-coupon market. Questions before you read further? Call (346) 248-1474 – a live person picks up, any hour.
When You Need Full System Cleaning
- Your home is more than five years old and the ducts have never been cleaned. The Woodlands was built out in phases from the late 1990s through the mid-2010s, and many Village of Creekside Park and Sterling Ridge homes are now past the point where visible debris accumulation at the registers is a reliable warning sign. By the time you can see it at the grille, the buildup inside the plenum – the main trunk feeding all those runs – is often substantial. A camera inspection makes the actual condition visible before you commit to anything.
- You’ve completed a renovation or had contractor work done. Drywall dust, insulation fibers, and construction particulate travel fast in a duct system with a running air handler. Post-renovation contamination is one of the most common reasons The Woodlands homeowners call us, particularly in Alden Bridge and Panther Creek where older homes are regularly updated. A full system clean removes what settled during the project, not just what’s visible on the registers.
- Someone in the household has unexplained respiratory symptoms or allergy flares that worsen indoors. We’re not diagnosing anyone’s health, but we do know what a camera finds inside a duct system that’s been accumulating pollen, mold spores, pet dander, and humidity-related debris for a decade. The Woodlands sits in a humidity corridor that makes mold colonization inside duct liners more common than in drier Texas markets; if the camera shows it, the photo record shows it to you.
- Your HVAC system is being replaced or the evaporator coil was just serviced. Installing new equipment into contaminated ductwork shortens equipment life and immediately degrades air quality. A full system clean before or immediately after new equipment goes in is the only way to protect that investment from day one.
- You’re buying or selling a home in The Woodlands. In neighborhoods like Carlton Woods or Cochran’s Crossing, where homes frequently trade above $600,000, buyers are asking questions about duct condition as part of due diligence. A documented photo record of a completed full system clean – delivered to the customer as a standard job deliverable – answers those questions with evidence rather than seller assurances.
- Your energy bills have increased without an obvious explanation. Debris accumulation on the evaporator coil and inside supply runs forces the air handler to work harder to move the same volume of conditioned air. In a South Texas climate where systems run 10 to 11 months a year, that resistance adds up on every utility bill. A full system clean, particularly one that includes coil housing and blower cleaning, can restore airflow efficiency without a refrigerant call.
Our Full System Cleaning Process
-
Camera Inspection and Written Scope Before Any Work Starts
Before a tool touches the system, we run a camera through a representative sample of your duct runs and photograph what’s inside. You see the actual condition – debris depth, any visible mold growth or moisture staining, insulation breakdown, pest evidence – before we hand you a written price. This is Haven Standard Clause 1: written price before any work starts, no exceptions. In The Woodlands homes with flexible duct runs in attic spaces, this inspection also catches collapsed or kinked sections that a cleaning alone won’t fix, so we can quote any necessary duct repair at the same time rather than after the fact.
-
System Isolation and Negative-Pressure Setup
Negative-pressure extraction means the cleaning equipment creates a controlled vacuum across the entire duct circuit before any agitation begins. We seal off registers and grilles throughout the house, connect a Nikro negative-air machine to the system’s main trunk or the air handler cabinet, and establish consistent negative pressure before any brushing or air-washing starts. This matters because agitation without negative pressure simply redistributes debris – into the living space, into the air handler, or to cleaner sections of the system. Containment comes first.
-
Source-Removal Cleaning of Every Duct Run
With the system under negative pressure, we work each supply and return run individually using a Rotobrush system – a rotating brush on a flexible cable that travels the full length of the duct and dislodges adhered debris while the negative-air machine extracts it. Every run gets worked from register to trunk, not spot-cleaned near the opening. For rigid ductwork sections common in older Woodlands homes, we supplement with air-whip tools that reach corners and elbows where flex-brush contact is limited. This is the step that separates source-removal cleaning from vacuum-at-the-register cleaning – the debris comes out of the duct, not just off the grille face.
-
Air Handler, Blower, and Evaporator Coil Housing Cleaning
The air handler cabinet is where all return air converges before conditioning and redistribution, which makes it the highest-concentration point for biological debris, dust cake, and anything that bypassed the filter. We clean the blower wheel (the fan assembly that moves air through the system), the evaporator coil housing, and the interior cabinet surfaces. A clogged blower wheel or a debris-coated coil housing restricts airflow and strains the motor – both problems that show up later as higher utility bills or a premature service call. We photograph the blower and cabinet before and after as part of the standard documented record.
-
Register and Grille Cleaning
Every register face and grille is removed, cleaned, and reinstalled. In two-story Woodlands homes with 25 or more registers spread across multiple zones, this step takes longer than most homeowners expect – but it’s part of a complete system clean, not an add-on. Debris that accumulates in the grille slots recirculates the moment the system runs.
-
Post-Cleaning Camera Verification and Photo Record Delivery
After cleaning is complete, we run the camera through the same runs photographed at the start. The before-and-after photo record is delivered to you as a standard job document – the same format we’ve used on every job since we started in 2013. You can see what was removed and what the duct interior looks like now. If a run doesn’t meet the standard we set at the written quote, we go back in. That’s the 365-Day Done Right Promise, and it’s in writing on every invoice, not subject to manager approval.
BeforeAfterFull System Cleaning Pricing in The Woodlands
Air Duct Cleaning services in The Woodlands typically run between $450 and $950 for a single-system residential home. Two-system homes – common in larger properties in Carlton Woods, Creekside Park, and the Village of Research Forest – generally fall in the $800 to $1,600 range, depending on duct count, access conditions, and whether supplemental work (coil cleaning, sanitizing, duct repair) is needed. These are real ranges from real jobs in The Woodlands market, not teaser prices.
| Home Profile | Typical Price Range |
|---|---|
| Single system, up to 2,500 sq ft, standard access | $450 – $620 |
| Single system, 2,500 – 4,000 sq ft | $580 – $780 |
| Single system, 4,000+ sq ft or complex access | $750 – $950 |
| Dual system, standard access | $800 – $1,200 |
| Dual system, large home or difficult attic access | $1,100 – $1,600 |
| Add: antimicrobial sanitizing treatment | $80 – $150 per system |
| Add: dryer vent cleaning (same visit) | $95 – $145 |
What affects the final price:
- Number of duct runs and registers (each one gets worked individually)
- Attic access conditions – The Woodlands’ high-humidity summers create a difficult environment for flexible duct runs, and sections with moisture damage or partial collapse may require duct repair quoted separately
- Whether the air handler and blower cleaning are included (they are, by default, in our full system scope)
- Add-on services like antimicrobial application using Abatement Technologies-compatible products, or a Guardsman-grade sanitizing treatment for homes with documented mold presence
Your written price is delivered after the initial camera inspection and before any cleaning begins. There is no version of a CleanRun job where work starts before you have a number in writing. If you have a written estimate from another company, bring it – we’ll put our number next to it in writing, free, no obligation. That’s our Free Second Opinion policy, and it applies to any written quote.
Call (346) 248-1474 to schedule the camera inspection. The inspection itself is included in the job cost when you proceed – there’s no separate diagnostic fee.
What’s Included in the Documented Photo Record
Every full system clean produces a photo record that travels home with you as a standard document, not an optional upgrade. It includes:
- Before photos of each duct run, taken at depth with the inspection camera – not a phone shot of the register opening
- After photos of the same runs, taken from the same camera positions
- Photos of the blower wheel and air handler cabinet, before and after
- A written scope of work noting every run cleaned, every register serviced, and any conditions observed (debris type, moisture evidence, insulation condition, access restrictions)
- A copy of the 365-Day Done Right Promise, written on the invoice
This record has practical value beyond the day of the job. For homeowners in The Woodlands who plan to sell within a few years, it’s a concrete document that answers buyer questions about system maintenance. For households with allergy or asthma concerns, it’s documentation of what was removed and when. And if anything doesn’t look right six months from now, it’s the baseline against which we evaluate a return visit under the 365-Day Promise.
CleanRun has kept this documentation standard on every job since 2013, across more than 52,000 homes served. Not because it’s a marketing point, but because a technician who can show you before-and-after photos has no reason to be vague about what they actually did.
The Crew Showing Up at Your Door
Under Haven Standard Clause 3 – Verified Crews – every technician is background-checked, uniformed, and identified by name before arrival. You know who’s coming before the truck pulls in. In neighborhoods like Grogan’s Mill and Indian Springs, where residents know their neighbors and notice unfamiliar vehicles, that’s not a small thing. Tomas Reyes built CleanRun on the principle that a homeowner letting a crew into their attic and living space deserves to know exactly who that crew is before the door opens.
Equipment on the truck includes professional-grade tools from Rotobrush and Nikro – brands with established reputations in the duct cleaning trade that you can look up independently before agreeing to a job. No proprietary black-box systems, no truck-mounted vacuums passed off as negative-pressure rigs. The equipment roster is what it is, and we name it on the page so you can verify it before we arrive.
FAQs – Full System Cleaning in The Woodlands
How long does a full system cleaning take in a typical Woodlands home?
A full system clean on a single-system home in the 3,000-3,500 square foot range common in The Woodlands takes roughly 3.5 to 5 hours with a two-person crew. Larger homes with two air handlers and 40-plus total runs routinely run 6 to 8 hours. We don’t cut the job short to make it to the next address – every run on the written scope gets worked, and the post-cleaning camera verification happens before we pack up. If you’re scheduling around your workday, plan for a half-day minimum and a full day for larger properties. Call (346) 248-1474 and we’ll give you a tighter estimate based on your system’s specifics.
Is full system cleaning different from the $79 specials advertised in The Woodlands?
Yes, in almost every meaningful way. The $79 model is typically a loss-leader where a technician arrives, runs a shop-vac at the registers, and then prices individual duct runs at $25-$50 each until the job hits $400 or more with none of the source-removal work completed. Full system cleaning, as CleanRun scopes it, means negative-pressure extraction across the entire duct circuit, Rotobrush agitation through every run, air handler and blower cleaning, and a documented photo record – all for a written price you have before work starts. The difference isn’t in the marketing language; it’s in the camera photos before and after. Call (346) 248-1474 if you’ve received a low-number quote and want a second written number to compare.
How often should a full system cleaning be done in The Woodlands climate?
For most Woodlands homes, every 3 to 5 years is a reasonable interval under normal conditions. The humidity in Montgomery County accelerates biological growth inside duct liners relative to drier Texas markets, so homes with a history of moisture issues, prior mold remediation, or aging flexible ductwork may warrant a shorter cycle. Households with multiple pets, smokers, or a recent renovation typically see visible accumulation faster than the average. After your first documented cleaning with a photo record, you have a baseline – the next inspection camera shows you exactly how much has changed, rather than relying on a technician’s verbal description. Call (346) 248-1474 if you’re not sure where your system falls on that timeline.
What’s the 365-Day Done Right Promise, and does it actually cover a re-clean?
The 365-Day Done Right Promise means that if any portion of the work CleanRun completed doesn’t meet the standard described in the written scope, we return and make it right at no charge, for 365 days from the job date. It covers workmanship – if a duct run we documented as cleaned shows recontamination attributable to incomplete cleaning rather than new debris introduction, we go back in. It’s written on every invoice, not a manager-approval policy subject to interpretation. It does not cover new contamination from a subsequent renovation, pest intrusion, or external event – but those cases are distinguishable with the before-and-after photo record from the original job. Call (346) 248-1474 if you have a specific question about whether your situation is covered.
Do I need to do anything to prepare before the crew arrives?
Clear a path to the air handler – in most Woodlands homes that means attic access, garage access, or a utility closet depending on system location. Make sure pets are secured away from the work areas, since negative-pressure equipment moves a significant volume of air and the access panels being removed can be startling. We’ll take care of register removal and reinstallation, furniture protection near work areas, and filter replacement (if you want a new filter installed at the end of the job, have one on hand in the correct size). Everything else is part of the job scope.
A Note on Duct Repair and Full System Cleaning
In The Woodlands, attic duct systems face conditions that accelerate deterioration: sustained summer heat above 130 degrees in unconditioned attic spaces, high ambient humidity, and the weight of accumulated insulation on flex duct runs over time. Camera inspections on full system cleaning jobs regularly find collapsed flex duct sections, disconnected duct boots at registers, and plenum seams that have separated – conditions that reduce airflow efficiency and allow unconditioned attic air to enter the supply stream.
When inspection finds these issues, we price the repair on the same written scope, at the same appointment, before any work starts. A full system clean on a duct circuit with significant leaks or collapses is worth less than it should be – conditioned air leaving through a disconnected boot never reaches the room it’s meant to serve, regardless of how clean the duct interior is. Cleaning and repair, when both are needed, are best addressed together.
