Why CleanRun Air Duct Cleaning Is Centennial’s Preferred Air Duct Cleaning Company
Centennial homes weren’t built yesterday. Most of the housing stock between Arapahoe Road and Orchard went up between 1975 and 1995, and the ductwork inside those attics has baked through 30-plus Colorado summers. Our crews have run camera inspections in hundreds of these houses and the failure patterns repeat block after block: embrittled flex liner, disconnected boots at the supply runs, return ducts pulling from wall cavities that were never sealed. We know what we’re going to find before we open the first register because we’ve worked the same floor plans in Willow Creek, Fox Hill, and Heritage Hills for years. Tomas Reyes, who leads our Centennial crews, can tell you exactly what your 1987 two-story likely has in the attic before he climbs the ladder.
Every Centennial job concludes with a Documented Photo Record. You get photographs of the inside of every duct run, before and after. You see what was in there and what it looks like when we’re done. That record, along with your written scope of work and the 365-Day Done Right Promise in writing, is yours to keep. If something isn’t right within a year, we make it right. Not as a courtesy. As a contract term.
Our Air Duct Cleaning Services in Centennial

We perform full-system source removal, not just register vacuuming. Here’s what that means for Centennial homeowners. We also run a complete Air Duct Cleaning operation, and every service below starts with a written price. Get the details on what each job covers before you commit.
Residential Duct Cleaning
The standard Centennial single-family home has 10 to 18 duct runs, most of them flex duct snaking through an unconditioned attic. We clean the supply side, the return side, the plenum, and the registers. The work uses negative-pressure extraction with a HEPA-filtered vacuum, so what we dislodge leaves the house rather than circulating through it. A typical residential job in Centennial takes four to seven hours depending on system size and accessibility.

Commercial Duct Cleaning
Centennial’s commercial buildings line Arapahoe Road, Dry Creek, and the I-25 corridor. The work differs from residential: larger trunk lines, multiple rooftop units, and often stricter scheduling windows. We coordinate with property managers and handle jobs before or after business hours when needed. Written pricing still applies, and every commercial run gets the same before-and-after documentation.

Supply Duct Cleaning
Supply ducts push conditioned air into living spaces. In Centennial homes with original flex duct, the supply side is where we most often find collapsed runs and tears at the boot connections, because supply runs take the hottest attic air during summer. We photograph each run’s interior and clean it back to the plenum, not just the first few feet visible from the register.

Return Duct Cleaning
Return ducts pull air back to the furnace. In 1980s-era Centennial construction, return ducting was frequently assembled from wall cavities and floor joists, not sealed metal or flex. That means return air drags dust from inside wall spaces, around framing, and through gaps in the original construction. If we clean only the supply side and ignore the return side, the dust comes back within months. We clean both, every job, no exception.

Video Inspection
Before we clean, we look. A camera inspection shows what’s actually inside your duct system: collapsed flex, disconnected boots, moisture staining, debris build-up, failed liner. In Centennial’s 30-to-45-year-old housing stock, skipping this step is how you pay for a cleaning that does nothing. We include a video inspection as part of the written scope on every residential and commercial job so you know what we found and what we did about it.

Centennial HVAC systems skew toward mid-1990s to mid-2000s equipment: Carrier and Lennox furnaces are common, along with Aprilaire media cabinets and Honeywell bypass humidifiers that were popular in tract builds of that era. Our teams carry familiar trade equipment including Rotobrush and Nikro negative-pressure systems, plus Abatement Technologies HEPA units for source-removal work. You’re welcome to look up any of those names before we show up. If your system uses a Guardsman or Aprilaire filter housing, we inspect and clean it as part of the full-system job.
Common Air Duct Cleaning Problems We See in Centennial Homes

- Delaminated flex duct in attic runs. Original flex from the 1980s and early 1990s has a plastic inner liner that becomes brittle after decades of 130°F+ attic heat. The liner cracks and separates from the insulation wrap, leaving bare fiberglass exposed to the airstream. The outer plastic jacket hides the damage from the outside, so the homeowner never sees it. We’ve documented this in homes across Piney Creek, Smoky Hill, and Willow Creek.
- Disconnected boots at the supply registers. The connection between the flex run and the register boot loosens or separates over time, especially in attics with extreme temperature swings. Conditioned air spills into the attic while attic dust gets pulled into the system. A camera inspection finds this in minutes; a standard cleaning without inspection misses it entirely.
- Return-side contamination from wall-cavity returns. Original construction in many Centennial subdivisions used panned joists and stud cavities as return-air paths. Those cavities are not sealed. The return side pulls dust from inside walls, around framing lumber, and from the basement or crawlspace. Cleaning supplies without fixing the return path means the system stays dirty.
- Fine alkaline dust accumulation from High Plains winds. Centennial’s low humidity and constant westerly wind keep fine dust airborne longer and push it into return-air systems. This dust is finer than what most Front Range cities deal with further north or west because the terrain east of Centennial is open and dry. It settles deep in duct interiors, which is why surface vacuuming at the registers doesn’t address it.

FAQs - Air Duct Cleaning in Centennial

Because the inner liner of the original flex duct has disintegrated. After 30 to 40 years in a Colorado attic, the plastic liner inside flex duct becomes brittle and separates from the insulation wrap. The outer jacket holds its shape, so the damage is hidden, but the exposed fiberglass sheds directly into the airstream. A basic cleaning that only vacuums the register openings will never touch this. The fiberglass is inside the return runs and the supply runs, not just at the registers. We find this in Centennial tract homes regularly. The fix is source removal under negative pressure plus replacement of failed flex. If you’re seeing white dust on furniture despite changing filters, call (806) 606-6902 for a written inspection scope; free estimates are standard.
Usually yes. Centennial condo and apartment buildings have shared duct systems or shared dryer vent stacks, and accessing the equipment often requires coordinating with a property manager for roof access, mechanical room access, or entry to multiple units. In some buildings, the HOA is responsible for the common ductwork, while the unit owner handles runs inside the unit. We work with HOAs and property managers throughout Centennial to schedule multi-unit access efficiently. Bring us the building rules and we’ll coordinate the rest.
Unraveled flex duct with exposed fiberglass. The inner liner has embrittled and split, the insulation has separated, and the outer wrap is the only thing holding the shape together. From the living space, it looks like a normal register. From the camera the attic, it looks like fiberglass is feeding directly into the air supply. Homeowners in Piney Creek and Smoky Hill regularly tell us they had no idea until we showed them the before photo. Call (806) 606-6902 and we’ll put that same camera inspection on your written scope.
Centennial’s dust is finer and stays airborne longer because humidity here runs much lower than in Denver’s urban core or in cities further north like Thornton where irrigation and tree cover moderate things slightly. The open terrain east and south of Centennial throws fine alkaline dust into the air on windy days, and that dust settles deep inside duct runs rather than clumping near registers. Most Centennial homes need a full cleaning every 3 to 5 years, more often if the home has original flex duct or if residents run the HVAC system continuously during wildfire smoke season. If you’ve noticed dust returning within months of a previous cleaning, the return side likely wasn’t done. We do both sides, every time.
Yes, and in shared-stack townhome configurations this matters more than in single-family homes. Lint from one unit’s dryer accumulates in the common stack, and if one unit’s run is partially blocked, it increases backpressure on every unit sharing that stack. Cleaning your own dryer vent removes your lint contribution and reduces the load on the shared duct, but the stack itself may also need cleaning if the building has gone years without it. In Centennial townhome communities, we coordinate multi-unit dryer vent cleaning with the HOA so the entire stack is cleared in one visit.

One More Thing About Centennial Ducts
Our crew worked a two-story colonial in Willow Creek where the homeowner reported persistent white dust on furniture despite replacing filters every 60 days. The camera inspection showed the return ducts were original flex, and the inner liner had disintegrated in three attic runs. Exposed fiberglass batting was shedding directly into the air handler. We performed full source removal under negative pressure, replaced the failed flex runs, and sealed the boots at the plenum. The dust stopped within a week. That is not an unusual story for Willow Creek, Fox Hill, or any of Centennial’s 1980s-era tract neighborhoods. It is what happens when duct systems age past three decades in unconditioned attic space, and it is exactly the kind of failure a filter change will never fix.
Our Air Duct Cleaning process exists for this specific situation: find the failure, document it, clean it, and repair what’s failed. If you live in Centennial and your home was built before 2000, there’s a good chance your ducts have never been inspected. You can keep wondering, or you can get a camera inside the system and know. Call (806) 606-6902 for a written estimate. We’ll show you the before photo before we quote you the after.
