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 Littleton, CO
Professional HVAC cleaning in Littleton typically runs $400-$800 for a complete system, with air quality treatments adding $200-$500 depending on the scope. CleanRun crews have worked the foothill zone long enough to know that Littleton’s combination of 40-year-old duct board, Chinook wind events, and recurring wildfire smoke creates contamination patterns we don’t see in flatter Denver suburbs. Call (720) 799-2292 for a written estimate before any work starts.
Why Littleton Homes Are Different
Littleton sits directly at the base of the Front Range foothills, making it ground zero for Chinook-driven dust surges that funnel fine particulates into home duct systems far more aggressively than flatter Denver suburbs to the east. The semi-arid climate at roughly 5,350 feet keeps winter humidity below 20%, so dust stays suspended longer and penetrates deeper into duct runs.
The housing stock compounds the problem. Ken Caryl Ranch, built out between 1979 and 1990, and the Columbine-area subdivisions are filled with ranch and split-level homes whose original forced-air systems include fiberglass duct board and early flex duct now 35-45 years old. Technicians regularly find delaminated duct board along interior seams, loose fiberglass fiber migration, and heavy debris accumulation from decades without professional cleaning. Wildfire smoke from the foothills has also left residual combustion particulates that standard filter changes cannot touch.

Before
AfterHVAC Cleaning in Littleton

Complete HVAC Cleaning in Littleton addresses the contamination that accumulates in 40-year-old systems exposed to foothill dust and wildfire smoke. The evaporator coil and blower assembly are the primary collection points for fine particulates that bypass standard filters, while the air handler housing often harbors debris from original construction that has never been removed.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow from registers, or a musty odor when the AC cycles on.
What it costs in Littleton
Evaporator coil cleaning typically runs $250-$450 depending on accessibility and contamination level.
How we do it
We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling, or dust puffing from registers at startup.
What it costs in Littleton
Blower assembly cleaning ranges from $200-$350 for standard residential units.
How we do it
We remove the blower wheel and housing, clean each blade with compressed air and solvent, balance the assembly, and document with photos.
What HVAC Cleaning Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower assembly cleaning | $200-$350 |
| Complete HVAC system cleaning | $400-$800 |
How often should HVAC cleaning be done in Littleton?
Every 3-5 years for most homes, but every 2-3 years if you have pets, recent wildfire smoke exposure, or original 1980s duct board. Call (720) 799-2292 and we’ll assess your system.
Does HVAC cleaning help with wildfire smoke residue?
Yes, but only when the evaporator coil, blower, and duct runs are all cleaned together, combustion particulates adhere to wet coil surfaces and redistribute through the home.
Air Quality & Sanitizing in Littleton

Air Quality & Sanitizing in Littleton targets the biological and particulate contamination that foothill dust and wildfire smoke leave behind in aging duct systems. The delaminated fiberglass duct board found in Ken Caryl Ranch homes can harbor mold spores and bacteria that standard cleaning does not address, while residual smoke odor compounds require targeted treatment beyond filtration.
Mold Treatment
Signs you need it
Visible growth near registers, persistent musty odor, or aggravated allergy symptoms when the system runs.
What it costs in Littleton
Mold treatment for duct systems ranges from $300-$600 depending on extent and access.
How we do it
We apply EPA-registered antimicrobial through the duct system, treat the source area with contact spray, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold or bacterial growth, frequent coil contamination, or occupants with respiratory sensitivities.
What it costs in Littleton
UV-C lamp installation runs $400-$800 including hardware and mounting.
How we do it
We mount a Honeywell or Aprilaire UV lamp at the coil location, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Mold treatment | $300-$600 |
| UV light installation | $400-$800 |
| Complete air quality package | $500-$1,000 |
Is UV light effective against wildfire smoke particles?
No, UV light targets biological growth on the coil, not particulate matter, smoke particles require filtration and duct cleaning instead.
How do I know mold treatment was actually done?
CleanRun provides before-and-after photos of treated areas and a written scope under Haven Standard Clause 1, the 365-Day Done Right Promise covers any recurrence.
