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 Company in Denver, CO
Air duct cleaning in Denver isn’t a one-size-fits-all job. Our city’s altitude, dry climate, and older housing stock all change how fast dust, pet hair, and construction debris build up inside ductwork. Cardinal Air Duct Cleaning handles all three core services – air duct cleaning, HVAC cleaning, and dryer vent cleaning – from our Denver office, and every job starts with a written price before any work begins. Call (737) 727-2314 to talk through your situation with a real person.
Why Denver Homes Are Different
Denver sits at 5,280 feet, and that elevation matters more than people expect. The air holds less moisture, so dust stays suspended longer and settles into duct runs faster than it would in a humid city. Homes in Washington Park, Berkeley, and Park Hill were mostly built between the 1920s and 1970s, which means galvanized steel ductwork that’s rigid and cleanable, but also decades of accumulated debris packed into return cavities. In newer developments like Central Park or Green Valley Ranch, builders often ran flex duct through unconditioned attics, and we regularly find drywall dust and sawdust from construction still inside those runs on first cleanings.
Winter heating season runs long here, sometimes late October into April. That’s five or six months of forced-air heat cycling through whatever is sitting in your ducts. Add in Denver’s spring wind season, when fine dust blows down off the Front Range, and you have a recipe for clogged coils and restricted airflow by midsummer. Homes near major arterials like Colorado Boulevard or Federal Boulevard pick up road dust more quickly than homes tucked into quieter streets in Highlands Ranch or Lakewood.
Our Main Denver Services
Most Denver homeowners reach out to us for one of three services. Here’s what each one involves locally, and each has its own dedicated Denver page with full pricing and process detail.
Dryer Vent Cleaning in Denver
Denver’s dry climate does one helpful thing: it keeps lint from clumping with moisture the way it does in humid cities. That said, lint still packs into dryer vent runs, especially in older Denver homes where vents route horizontally through basements or crawlspaces before exiting outside. We use rotary brush systems matched to your vent’s diameter and a HEPA vacuum at the exit point. If your dryer takes longer than one cycle to dry towels, that’s the signal to book. Full details on Dryer Vent Cleaning in Denver.

Air Duct Cleaning in Denver
Air duct cleaning in Denver is a two-part job: agitate, then extract. We use Rotobrush rotary brush systems to break debris loose from the duct walls, and Nikro HEPA-rated vacuums pull it out under negative pressure – meaning the loosened debris goes straight into the vacuum, not back into your living room. Denver homes with pets, recent remodels, or smokers in the house typically need this more than a checklist every few years. See Air Duct Cleaning in Denver for pricing and exact process details.

HVAC Cleaning in Denver
Your HVAC system has two components beyond the duct runs themselves: the blower motor and the evaporator coil. In Denver, that coil gets hit hard during cooling season because the system pulls in dry, dusty outside air. A coated coil drives up energy use and shortens equipment life. We open the air handler, clean the coil with professional-grade solutions, and service the blower assembly. Full scope and pricing are on the HVAC Cleaning in Denver page.
