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 Katy, TX
Air Duct Cleaning in Katy, TX typically runs between $299 and $599 for a standard single-family home, and most jobs are completed in three to five hours with a documented photo record of every duct run included. CleanRun Air Duct Cleaning Katy has served homeowners across Katy since 2013 – 52,000+ homes across the metro, every one quoted in writing before a panel comes off and photographed before and after the work is done.
Duct cleaning, done right, is not a shop-vac and an invoice. It is negative-pressure extraction (think of it as putting the duct system under a vacuum so debris travels toward the equipment, not back into your living space), combined with mechanical agitation that breaks up the compacted dust, pollen, and microbial buildup clinging to duct walls. CleanRun uses Rotobrush and Nikro equipment – professional-grade tools you can look up independently – because the equipment determines whether the debris actually leaves the house or just gets redistributed.

When You Need Residential Duct Cleaning
Katy’s climate does most of the work here. Long humid summers mean HVAC systems run hard for eight or nine months of the year, cycling the same air through the same duct runs thousands of times before the weather gives them a rest. That cycle accumulates debris faster than in drier climates, and homes built in Katy’s major expansion phases – Grand Lakes, Cinco Ranch, Firethorne, LaCenterra-area subdivisions – often have longer duct runs and more elbows than older, smaller floorplans, which means more surfaces for debris to cling to.
- Visible dust at registers within a day of cleaning. If you wipe a register grille and it’s coated again within 24-48 hours, the duct system upstream of it is shedding debris into the airstream. That’s not a dusting problem; it’s a duct problem.
- Musty or stale odor when the system kicks on. In Katy’s humidity, condensation inside duct runs – especially in attic-run sections where temperature swings are severe – creates conditions where microbial growth takes hold. The smell is the first sign, and a camera inspection will confirm it.
- Recent renovation or construction work. Drywall dust is one of the most damaging things that can enter a duct system. It’s fine enough to pass through some filters, and it coats coil fins and duct walls with a layer that doesn’t vacuum off easily. Homes in newer Katy developments that went through finish-out work often show heavy drywall debris at the first elbow of every run.
- Allergy or respiratory symptoms that worsen indoors. Katy’s spring cedar and ragweed seasons push allergen loads that accumulate inside duct systems. If symptoms are noticeably worse inside the house than outside, the duct system is a reasonable place to look.
- More than five years since the last documented cleaning. The EPA and NADCA reference a general guideline of three to five years for most residential systems under normal use. In Katy, with high system runtime and humidity, five years is the outer edge – not the starting point.
- A new home purchase. A pre-owned home’s duct history is usually unknown. Sellers rarely disclose the last cleaning date, and CleanRun’s camera inspection shows exactly what’s inside before you make any decisions. Several Katy homebuyers have called us after discovering the previous owner’s pets had been pushing dander through the system for years.
Our Residential Duct Cleaning Process
Every CleanRun job in Katy follows the same documented sequence. Nothing is skipped based on the size of the job or the age of the house. Haven Standard Clause 1 means the written price is delivered before step one begins – no surprises at the end.
- Pre-job camera inspection and written scope. Before any equipment enters the system, a camera goes into the main supply plenum (the distribution box that feeds all supply runs from the air handler) and each accessible duct run. What the camera finds is photographed and noted in the written scope. This is how CleanRun establishes a baseline – not an assumption about what’s inside. If a duct run is clean, we say so in writing. If the camera shows a debris build-up at the first elbow, that goes in the record too.
- Written price delivered before work starts. After the inspection, the written price is on paper. Haven Standard Clause 1 is not marketing language – it means the number you see before work starts is the number on the invoice when work ends. No “we found more than expected” add-ons without your written approval first.
- Source-removal extraction using negative-pressure equipment. A Nikro or Rotobrush collection unit is connected to the system and puts the duct network under negative pressure. Each duct run is then worked from the register back toward the plenum using rotary brush agitation, which breaks up compacted debris that suction alone cannot move. The debris travels toward the collection unit, not into your living space.
- Plenum and air handler cabinet cleaning. The supply and return plenums are cleaned by hand and by tool – they’re the largest debris collection points in the system and the ones most cleaning companies skip because they require more time. The air handler cabinet interior is also inspected and cleared of accessible debris accumulation around the coil housing.
- Post-cleaning camera documentation. Every duct run that was photographed before the cleaning is photographed again after. The before-and-after photo record is delivered to you as a standard job deliverable – not an optional add-on. This is the evidence that separates documented work from a truck visit with a receipt.
- Written job summary and 365-Day Done Right Promise confirmation. The job summary lists every run cleaned, every finding from the camera inspection, and confirms the 365-Day Done Right Promise in writing. If anything is not right within 365 days of the job, CleanRun makes it right – not subject to manager approval, backed in writing on every invoice.
BeforeAfterResidential Duct Cleaning Pricing in Katy
Residential duct cleaning in Katy costs between $299 and $599 for most single-family homes. That range covers the documented photo record, the written price before work starts, the 365-Day Done Right Promise, and the full extraction process described above – not a baseline service with add-ons attached. Here’s what moves the number within that range:
| Factor | Typical Impact on Price |
|---|---|
| Home size (square footage / number of vents) | Primary driver – more duct runs mean more time and documentation |
| Number of HVAC systems (single vs. dual zone) | Dual-system homes in Katy’s larger floorplans add $80-$150 to the range |
| Duct material (flex duct vs. sheet metal) | Flex duct common in Katy construction requires adjusted agitation technique; minimal price difference, but noted in the scope |
| Debris load found at inspection | Heavy build-up (post-renovation, 10+ years uncleaned) may add time; always disclosed in writing before work begins |
| Sanitizing treatment (optional) | EPA-registered antimicrobial fogging adds $75-$125 if requested after inspection |
What you will not see on a CleanRun invoice: charges that weren’t on the written price before work started. Haven Standard Clause 1 makes that a structural promise, not a customer-service gesture.
For an exact written price on your Katy home, call (346) 666-7165. The estimate is free, the number is fixed before we start, and if you have a written quote from another company, CleanRun will put its own number next to it in writing – at no cost to you.
What the Documentation Looks Like
A lot of duct cleaning companies talk about thoroughness. CleanRun photographs it. After every job in Katy, you receive a photo record showing the interior of each duct run before the cleaning started and after it was completed. Not representative shots – every run, documented individually.
This matters for a specific reason: duct cleaning is one of the few home services where the customer cannot see the work happening. A technician can run a vacuum for two hours and leave the debris exactly where it was. The only way to verify the difference is a camera image. CleanRun has produced this documentation on every job since 2013 – it is part of the standard job deliverable, not an upgrade tier.
The written job summary you receive also includes the technician’s name (background-checked, uniformed, identified by name before arrival under Haven Standard Clause 3: Verified Crews), the scope of work completed, any findings noted during the pre-job inspection, and the written confirmation of the 365-Day Done Right Promise.
Katy-Specific Considerations
Katy’s housing stock has a few characteristics that affect how residential duct cleaning plays out in practice.
Most homes built in Katy after 2000 use flexible duct (flex duct) rather than rigid sheet metal – it’s faster to install and works fine when properly supported, but it develops sags and low points over time where debris and moisture collect. A camera run through a sagging flex duct in a Katy attic often shows a debris pocket at the low point that a straight shop-vac pull would miss entirely. Rotobrush agitation followed by negative-pressure extraction is the correct approach for these sections.
Attic-run duct systems in Katy also face severe thermal stress. Attic temperatures in Harris County regularly hit 140-160°F in July and August, which accelerates flex duct degradation and can cause separation at fittings. CleanRun’s camera inspection catches these separations – a disconnected duct run is an air quality and energy issue that cleaning alone won’t fix, and it gets noted in the written scope. Duct repair is a separate service, but you’ll know about it in writing before anyone suggests adding it to the job.
Homes in areas like Cinco Ranch, Firethorne, Cross Creek Ranch, and Seven Meadows tend to have larger square footage and longer duct runs than the Katy average. These homes almost always have dual-zone HVAC systems, which means two air handlers, two sets of supply and return plenums, and roughly twice the number of duct runs to document. The written price reflects that accurately.
FAQs – Residential Duct Cleaning in Katy
How long does residential duct cleaning take in a typical Katy home?
Most single-family homes in Katy take three to five hours from the start of the camera inspection to the delivery of the photo record. Larger homes – 3,500 square feet and above, or dual-zone systems common in Cinco Ranch and Cross Creek Ranch – run closer to five to seven hours. The time is driven by the number of duct runs that need to be individually agitated, extracted, and photographed. A job that wraps in 90 minutes almost certainly skipped steps. Call (346) 666-7165 and give us your square footage; we’ll put a time estimate in writing alongside the price.
Is duct cleaning worth it, or is it just a scam?
Duct cleaning is worth it when the work is actually done – and that’s the part the industry has a documented credibility problem with. The EPA notes that duct cleaning has not been shown to prevent health problems by itself, but also that ducts can harbor contaminants that it makes sense to remove. The honest answer is: a Video Inspection first. If the camera shows significant debris build-up, biological growth, or post-renovation dust, cleaning addresses a real condition. If the camera shows relatively clean duct walls, CleanRun will tell you that in writing and not push a service you don’t need. The photo record is what separates a documented result from a truck visit. Before agreeing to any duct cleaning in Katy, ask the company to show you the camera footage before and after. If they can’t or won’t, that tells you what you need to know.
How often should ducts be cleaned in a Katy home?
Every three to five years is the general guideline for most residential systems; in Katy, with high system runtime and elevated humidity for much of the year, three to four years is a more practical interval for homes under normal use. That interval shortens if you’ve had renovation work, if there are pets in the home, if anyone in the household has respiratory sensitivities, or if the previous cleaning wasn’t documented. A camera inspection is the only way to know for certain where your system sits – and CleanRun will show you the footage before recommending anything.
What is the 365-Day Done Right Promise, and what does it actually cover?
The 365-Day Done Right Promise means that if the work CleanRun performed is found to be incomplete or not done correctly within 365 days of the job, CleanRun returns and makes it right at no additional charge. It’s in writing on every invoice – not a verbal assurance, not subject to manager review. It covers the cleaning work performed: if a duct run that was documented as cleaned shows the same pre-cleaning condition within that window, that’s covered. It does not cover new debris accumulation from normal system operation over time, which is a different thing entirely. The distinction is clear in the written job summary. If you have questions about what’s covered in your specific situation, call (346) 666-7165 and ask – you’ll get a straight answer.
