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.
Fast, Reliable Air Duct Cleaning Across Clayton
Air duct cleaning in Clayton typically costs $425 – $695 for a standard single-system tract home, with a full written price agreed before any work starts. We work throughout Clayton, from the subdivisions off Marsh Creek Road up through the neighborhoods around downtown, and our process is built around one flat price per system, not a per-vent figure that climbs once the technician starts counting registers. The short version: we show up with professional-grade equipment, document your ducts with a camera before and after, and hand you a written price before a single duct is touched. If you want a straight answer on what your system needs, call (737) 727-2314.
Why Cardinal Air Duct Cleaning Is Clayton’s Preferred Air Duct Cleaning Company
Clayton homeowners call us because we treat a duct cleaning like what it actually is: a mechanical cleaning job with a defined scope, a defined price, and photographic proof. Most homes here are tract builds from the late 1970s through early 1990s, and the systems are original or first-replacement flex-duct runs that have rarely, if ever, been opened up. That is not a generic observation. It changes how we clean, how long the work takes, and what you should expect to pay. Our Air Duct Cleaning team runs Rotobrush agitation tools and Nikro HEPA negative-air machines specifically because Clayton’s flex-duct stock responds differently than rigid metal. You get an honest look at the ductwork, not a shop-vac pass and a bill.
Every Clayton job comes with a written price before work starts, background-checked techs in uniform, and before-and-after camera photos of your own ducts. The 365-Day Done Right Promise applies to every booking: if the work is not right within a year, we return and correct it at no charge. No fine print, no exclusions for the things we quoted. Omar Haddad runs the crew that serves Clayton, and the standard is simple: document, clean, prove it.
Commercial Air Duct Cleaning in Clayton
Commercial Air Duct Cleaning in Clayton covers offices, retail spaces, restaurants, and any building with a forced-air HVAC system larger than a single-family setup. The job here is source removal: we set up negative-pressure containment so loosened debris flows into a HEPA-filtered vacuum instead of back into occupied rooms, then work the ducts mechanically with Rotobrush agitation tools section by section. For a Clayton commercial space, the work includes supply and return runs, the air handler, coils, and the blower assembly. A typical Clayton commercial system runs $1,200 – $3,800 depending on square footage and the number of rooftop units or split systems involved.
Video Inspection Before and After
We run a camera through every commercial system we clean in Clayton before touching anything, then again after the job. The inspection shows exactly what is inside the ducts, including the ribbed lint accumulation that builds on older flex runs. You see the before-and-after footage from your own building, not a stock photo from a training manual.
Restaurant and Retail Systems
Clayton restaurants deal with grease-laden vapor that a residential system never sees, and retail spaces often run longer hours with more foot traffic pulling debris through returns. We adjust the cleaning scope for higher-use commercial equipment and can quote a flat per-system price for buildings with multiple units. A written estimate is always provided before work begins.
Air Duct Cleaning Services in Clayton
Our Air Duct Cleaning Services in Clayton cover residential full-system cleaning, supply and return duct cleaning, air handler and blower service, and video inspection of the entire run. A full system clean for a typical Clayton tract home runs $425 – $695, and that price is per system, not per vent. We agree on the number before the van arrives and it does not move once we count registers. The work includes the supply runs, return runs, air handler cabinet, blower motor, and coils. No compressed-air blow-and-go; we use negative pressure and mechanical agitation with HEPA filtration on every job.
Supply and Return Duct Cleaning
Supply ducts deliver conditioned air to rooms, return ducts pull it back to the air handler. Both collect debris, but Clayton’s 1980s-era flex return runs are often worse than the supplies because they pull from every room continuously. We clean both, document both, and show you the camera footage from both.

Full System Cleaning with Air Handler Service
The air handler is where the blower motor sits, and in Clayton homes with decades-old systems, that motor often carries a mat of gray lint that has never been removed. Source removal means cleaning that motor and cabinet, not adding it as a surprise line item. It is part of the flat per-system price.

Trusted Brands We Service in Clayton
We service and clean systems built around Honeywell and Aprilaire filtration components, and we run Abatement Technologies containment units on jobs where the ductwork needs isolation. We do not stock every part for every system on the truck, but for Clayton jobs we schedule work so that common Honeywell filter housings and Aprilaire media replacements can be on hand when the tech arrives. That cuts the turnaround for homeowners who need a filter upgrade or replacement during a cleaning visit. You will know the brands involved in your system before we start, and the written quote lists any parts separately from the cleaning scope.
Common Air Duct Cleaning Problems We See in Clayton Homes
- Ribbed lint accumulation on original flex duct: Clayton’s tract homes from the 1980s and early 1990s were built with flex-duct runs that have internal ribbing. Dust and lint catch on those ribs and build up in a pattern that rigid metal ducting does not show. Camera inspection reveals it clearly, and mechanical agitation is the only way to remove it fully.
- Caked blower motors in air handler closets: The blower motor is downstream of the filter in many Clayton systems, meaning everything the filter misses lands on the motor. Homes that have not been cleaned in 20 years often have a felt-like mat on the motor. This is a source-removal item, not an upsell, and it is included in the flat system price.
- Return duct neglect in two-story layouts: Two-story Clayton homes with long horizontal return runs collect dust along the entire length, but standard quote-by-register pricing often skips or under-cleans the return. Our per-system pricing covers the full return run, and the camera footage shows it was actually cleaned.
- Post-construction dust from remodels: Clayton has a steady pattern of kitchen and room remodels on the 1980s housing stock, and drywall dust settles deep into the duct system within days. A remodel is a good trigger for a full cleaning, even if the system was cleaned a few years earlier. The dust load is not gradual in those cases.

FAQs About Air Duct Cleaning in Clayton
Every 4 to 7 years for most Clayton homes, but you should not clean on a calendar alone. Homes with original 1980s flex duct, pets, recent remodels, or a visible dust film on the blower motor may need it sooner. A camera inspection is the honest way to know, and we provide that as part of the written estimate. Call (737) 727-2314 and we will walk you through what the footage shows.
Per system, always. You get one flat price for the full system including supply runs, return runs, air handler, and blower motor. Nothing is added when the technician counts registers or finds a long return run. Call (737) 727-2314 for a written quote before you commit.
You get camera footage from inside your own ducts, captured before any cleaning starts and again after the job is complete. The images show the same duct IDs side by side so you can see what was removed. We hand you the before-and-after set as part of the job, not as an optional add-on. That is the Relay Standard, and it applies to every Clayton booking.
Yes. We clean commercial systems in Clayton including offices, retail spaces, and restaurants. The process is the same: camera inspection, negative-pressure containment with HEPA filtration, mechanical agitation, and a written flat price per system before work starts. Commercial pricing in Clayton typically runs $1,200 – $3,800 depending on the system count and square footage. Call (737) 727-2314 for a site assessment.
It can reduce the dust load in the air if the ducts are genuinely the source, and many Clayton homeowners report less dust settling after a full cleaning. But duct cleaning is not an allergy cure, and we will not sell it as one. We clean what is in the ducts and show you exactly what came out. If your allergy issue persists, the next step is a filtration discussion, which we can help with using Honeywell or Aprilaire products. Call (737) 727-2314 and we will give you an honest read on whether cleaning is the right move for your home.
