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.
Air Duct Cleaning in Centennial, CO
HVAC cleaning in Centennial typically runs $350-$650 for a whole-system service, with most jobs completed in a single scheduled visit. We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Centennial from our Denver office to clean duct systems in neighborhoods where the housing stock was built during the 1970s-1990s suburban expansion. Our written price arrives before any work starts, and every duct run is photographed before and after. Call (720) 513-5159 for a free estimate.
Why Centennial Homes Are Different
Centennial was incorporated in 2001 from unincorporated Arapahoe County, so nearly every home here dates to the 1970s-1990s build-out. In Willow Creek, Foxridge, and Piney Creek, we’re working with original fiberglass-lined ductwork that is now 30-50 years old. Colorado’s chronically low humidity, sitting at roughly 5,900-6,200 feet on the semi-arid high plains, degrades that fiberglass lining. It sheds fibers and traps decades of Front Range prairie dust plus wildfire-smoke particulates that standard filters cannot catch.
The typical Centennial home is a two-story, single-family tract house with a finished basement, creating large multi-zone duct systems. Basement return-air chases pull in concrete dust and soil particulates from the slab level. Chinook winds and increasingly frequent wildfire seasons push fine particulate matter deep into ductwork. In Foxridge and Willow Creek, crews regularly open trunk lines to find fiberglass liner crumbling from the sheet metal after 40-plus years of dry-air cycling. That turns what looks like routine cleaning into a liner integrity call, and we quote a liner inspection before committing to a flat price in those ZIP codes.
Our Main Centennial Services
Centennial homeowners call us most often for these three services:
Air Duct Cleaning in Centennial
We clean the full supply and return network in Centennial homes, from the plenum, the main distribution box, through every duct run, the individual branch lines, to each register, the wall or floor vents. In older neighborhoods like Piney Creek, we assess fiberglass liner condition before starting because brittle liner cannot withstand aggressive agitation. Every job ends with a Documented Photo Record of every duct run. Air Duct Cleaning in Centennial is scheduled by the system, not by the vent.

Dryer Vent Cleaning in Centennial
Dryer vent blockages are common in Centennial’s two-story tract homes where the vent run spans a finished basement and an exterior wall. We remove lint accumulation with rotary brushing and negative-pressure extraction, then verify airflow at the termination. Our written price covers the full run from appliance to exterior hood. Dryer Vent Cleaning in Centennial includes a photo of the blockage before removal.

Duct Repair & Sealing in Centennial
Centennial’s aging duct systems develop leaks at trunk-line seams and register boots, especially where thermal expansion has stressed connections over decades. We seal accessible leaks with mastic or metal-backed tape and replace damaged sections when liner degradation has compromised the duct wall. A written scope and price precede any cutting or sealing. Duct Repair & Sealing in Centennial carries the 365-Day Done Right Promise.

Before
AfterHVAC Cleaning in Centennial

Centennial’s 1970s-1990s housing stock runs HVAC systems hard through dry winters and wildfire-smoke summers, and the evaporator coils and blowers in these units accumulate a unique mix of prairie dust, wildfire ash, and degraded fiberglass fibers. We clean the full mechanical system, not just the ducts, because a clean coil and blower mean nothing if the air handler is circulating debris back into freshly cleaned ductwork. HVAC Cleaning from CleanRun includes the components competitors often skip.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or a musty smell when the AC cycles on in July.
What it costs in Centennial
Evaporator coil cleaning in Centennial typically runs $180-$320 as a standalone service, or $120-$200 when bundled with a full HVAC cleaning.
How we do it
We access the coil through the plenum, apply foaming cleaner from Nikro equipment, rinse with low-pressure water, and photograph the coil before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating across zones, or dust puffing from registers when the system starts.
What it costs in Centennial
Blower cleaning in Centennial typically runs $150-$280 as a standalone service, or $100-$160 when bundled with a full HVAC cleaning.
How we do it
We remove the blower assembly, clean the squirrel cage and housing with compressed air and contact vacuum, balance the fan, and photograph all stages.
What HVAC Cleaning Costs in Centennial
| Item | Typical range in Centennial |
|---|---|
| Full HVAC cleaning (coil, blower, air handler) | $350-$650 |
| Evaporator coil cleaning (standalone) | $180-$320 |
| Blower cleaning (standalone) | $150-$280 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your registers blow clean air but the system runs longer than it used to, or you smell must when the AC starts, the coil or blower is likely fouled. We inspect both with a borescope before quoting. Call (720) 513-5159 for a free estimate.
Can HVAC cleaning fix hot and cold spots in my Centennial home?
It can help if the spots are caused by restricted airflow from a dirty coil or unbalanced blower, common in Piney Creek’s two-story systems. If duct leaks are the cause, we quote duct sealing separately. Call (720) 513-5159 for a free estimate.
Air Quality & Sanitizing in Centennial

Centennial’s combination of 30-50-year-old fiberglass duct liner, chronically low humidity that keeps particles airborne, and recurring wildfire smoke creates conditions where biological growth and persistent odors take hold in ways standard cleaning cannot address. We treat the source, not the symptom, with applications that target what the camera shows inside the ductwork. Air Quality & Sanitizing from CleanRun is quoted with a written price before any chemical is introduced.
Mold Treatment
Signs you need it
Visible dark growth on register boots, a wet cardboard smell when the system runs, or recent water intrusion in the basement return chase.
What it costs in Centennial
Mold treatment in Centennial typically runs $400-$750 depending on the number of affected duct runs and whether liner replacement is needed.
How we do it
We apply an EPA-registered antimicrobial through a fogging system, let it dwell per manufacturer specification, then extract residue and photograph treated runs.
UV Light Installation
Signs you need it
Recurring mold or biofilm growth despite cleaning, or a household member with respiratory sensitivity to airborne contaminants.
What it costs in Centennial
UV light installation in Centennial typically runs $450-$850 including the lamp, housing, and electrical connection to the air handler.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and show the customer the installation photo.
What Air Quality & Sanitizing Costs in Centennial
| Item | Typical range in Centennial |
|---|---|
| Mold treatment (whole system) | $400-$750 |
| UV light installation | $450-$850 |
| Bacteria sanitizing (whole system) | $300-$550 |
Is UV light worth it in Centennial’s dry climate?
Low humidity does not prevent mold in ductwork; it prevents moisture from weighing spores down so they circulate instead of settling. UV-C at the coil kills what lands before it colonizes. Call (720) 513-5159 for a free estimate.
Will sanitizing chemicals leave residue in my ducts?
We use products formulated for HVAC application that break down to inert compounds; we extract liquid residue and verify dryness with a moisture meter before closing the system. Call (720) 513-5159 for a free estimate.
Brands We Service in Centennial
We stock parts and service equipment from Honeywell, Aprilaire, Rotobrush, and Nikro, with common filters, UV lamps, and cleaning heads carried on every Centennial truck. Most replacement parts arrive next-day if not stocked. See our brands for the full roster.

FAQs About Air Duct Cleaning in Centennial

No permit is required for standard residential duct cleaning in Centennial. If our inspection reveals degraded liner requiring duct modification or replacement, we handle any necessary permitting under the H.A.V.E.N. Standard and include those costs in the written scope.
Wildfire smoke carries ultra-fine particulate matter, particles smaller than 2.5 microns, that embeds in fiberglass liner and passes through standard filters. Standard household dust is coarser and settles in trunk lines. Smoke residue requires targeted treatment, not just extraction, and we assess for this during our initial camera inspection.
Most Centennial HOAs do not regulate indoor maintenance scheduling, though some gated communities require contractor vehicle registration at the gate. We carry general liability and workers compensation documentation and provide proof on request. Ask your HOA about any specific contractor requirements when you book.
