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.

Our Air Duct Cleaning Services in Centennial
Residential Duct Cleaning
Most Centennial homes were built between the late 1970s and early 2000s, which means most carry duct systems that have never been professionally cleaned. Our residential service starts with a video inspection of your full system, then performs source removal using Rotobrush agitation tools under negative pressure with HEPA filtration. We photograph every duct run before and after. The photo record is yours as a standard deliverable, not an upsell.
Commercial Duct Cleaning
Centennial’s commercial buildings along Arapahoe Road and near the Centennial Airport corridor face the same High Plains dust loading as residential structures, often with more complex rooftop HVAC configurations. We clean commercial supply and return systems with the same documentation standard: written scope, written price, photo record of every run. Our equipment includes Nikro and Abatement Technologies negative-pressure systems sized for larger ductwork.
Supply Duct Cleaning
Supply ducts push conditioned air to your registers, and in Centennial’s 1980s-era homes with finished basements, they often include long flex-duct runs to remote rooms. We’ve found crushed and disconnected supply lines behind finished ceilings in Willow Creek and Piney Creek homes more times than we can count. Our supply duct service includes camera inspection to locate these failures, agitation cleaning of the full run, and documentation of what we found and what we fixed.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in Centennial’s slab-on-grade and crawl-space ranch homes, they’re where the clay dust collects. Technicians working eastern-facing neighborhoods near the Cherry Creek corridor consistently find heavy reddish-brown accumulation in return plenums even in homes with 30-day filters changed on schedule. That’s the signature of upslope wind events pushing High Plains soil dust through foundation and rim-joist gaps. We clean the full return path and photograph the before and after. If we find gaps pulling unfiltered air, we note them in writing so you can decide on sealing.
Full System Cleaning
A full system cleaning covers supply ducts, return ducts, the plenum (the central distribution box), and accessible components of the air handler. In Centennial’s three-zone homes with basement additions, this means cleaning more duct footage and more connection points where flex duct meets hard pipe. We quote this as one flat price per system, agreed in writing before we start.
Video Inspection
Our video inspection service uses a camera on a flexible snake to show you the inside of your ducts before any cleaning decision. In Centennial’s older homes, this often reveals sagging flex duct, debris traps at low points, or disconnected runs that explain weak airflow to specific rooms. The video becomes part of your documented job record. We recommend this for any 1980s-1990s home with airflow complaints or rooms that never reach temperature.
Our Air Duct Cleaning team serves the full metro area with the same documentation standards.

BeforeAfterTrusted Brands We Service in Centennial
We clean and service duct systems connected to all major HVAC brands, and we use professional-grade equipment you can verify independently: Rotobrush agitation systems, Nikro and Abatement Technologies negative-pressure extractors, and Honeywell and Aprilaire air quality components. These aren’t consumer tools. They’re trade-recognized brands specified for source removal under NADCA guidelines. If your Centennial home has an Aprilaire media air cleaner or a Honeywell electronic air purifier, we inspect and document its condition as part of the full system clean. We don’t sell equipment we can’t name and show you.
Common Air Duct Cleaning Problems We See in Centennial Homes
- Original 1980s flex duct sags at low points in Colorado’s chronically low humidity, creating debris traps and mold-friendly moisture pockets that restrict airflow to finished-basement zones. The camera often shows a 2-3 inch buildup where the duct belly has lost support.
- Foundation and rim-joist gaps in slab-on-grade ranch homes admit fine reddish-brown clay dust during Chinook upslope events, loading return plenums even with clean 30-day filters. This isn’t a filter failure. It’s a building envelope issue that duct sealing addresses.
- Wildfire smoke seasons drive ultrafine particulate deep into ducts where low humidity causes it to bind to interior surfaces rather than remaining suspended. Surface wiping of registers misses this contamination; source removal with agitation and negative pressure is required.
- Long flex-duct runs to remote basement registers get crushed during finishing work or degrade at connection points, cutting airflow to the rooms that need it most. We find this in Piney Creek split-levels and Willow Creek ranches with basement rec rooms added in the 1990s.
Pricing for Air Duct Cleaning in Centennial, CO
A typical residential full-system duct cleaning in Centennial runs $380-$680 for a single-zone home, $520-$890 for a two-zone system, and $680-$1,150 for a three-zone home with finished basement.

FAQs - Air Duct Cleaning in Centennial
The reddish-brown dust is High Plains clay soil, and it enters through foundation and rim-joist gaps rather than through your filter. Centennial’s eastern neighborhoods sit on exposed prairie where upslope wind events push fine soil dust directly into crawl spaces and slab edges, then into return-air intakes. Changing your filter more often won’t stop this because the dust isn’t coming through the duct system; it’s coming in around it. We document these gaps during our video inspection and note them in your written scope so you can address sealing separately from cleaning. Call (720) 799-2292 for a free estimate.
Not automatically. We inspect first. The 1980s flex duct used in Centennial’s ranch and two-story homes degrades in Colorado’s low humidity, sagging at supports and sometimes cracking at connection points. During cleaning, we camera-inspect every run and photograph what we find. If a section is crushed, disconnected, or degraded beyond cleaning, we note it in writing with a repair price before doing any replacement work. Most systems clean successfully without replacement. Some need one or two runs reconnected or supported. The written scope you approve before we start includes exactly what we’ll do and what it costs. Call (720) 799-2292 for an inspection.
We clean each zone separately, sealing off the others to maintain negative pressure in the active zone. The basement zone typically has the longest flex-duct runs and the most connection points, so it takes the most time. We access the plenum through the air handler, run agitation tools through each supply and return line, and capture debris with a HEPA-filtered negative-pressure collector. Every run is photographed before and after. In Centennial’s three-zone homes, the job typically takes 4-6 hours. The flat price covers all zones; we don’t add per-vent charges. Call (720) 799-2292 for a written quote.
Yes, because of Centennial’s higher elevation and lower humidity. At roughly 5,900 feet, Centennial’s drier air causes ultrafine wildfire particulate to bind more tightly to duct interiors than in Denver’s slightly more humid conditions. When homeowners seal up and recirculate indoor air during smoke events, that bound particulate accumulates in layers that standard surface cleaning won’t remove. Our source removal process with agitation and negative pressure is designed for this. We’ve documented heavy accumulation in Centennial return plenums after particularly active smoke seasons. Call (720) 799-2292 to schedule post-season inspection.
Every 3-5 years for homes with standard fiberglass filters, or every 2-3 years if you have pets, allergies, or have completed recent remodeling. Homes in this build era that have never been cleaned should start with a full inspection and cleaning, then establish a schedule based on what the camera shows. Centennial’s combination of aging duct infrastructure and high particulate loading from prairie winds means these systems accumulate debris faster than newer, tighter construction. The photo record from your first cleaning becomes the baseline for comparing future accumulation. Call (720) 799-2292 to set up an initial inspection.
