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.

AfterAir Duct Cleaning in Littleton, CO

Littleton’s position at the foot of the Front Range puts its homes first in line when wildfire smoke rolls out of Jefferson County’s foothills. The city’s large stock of 1970s-1990s homes in Ken Caryl Ranch and Columbine Valley still runs original ductwork that has never seen professional cleaning. Our crews coordinate dispatch from the Denver office and serve Littleton locally.
Why Littleton Homes Are Different
At roughly 5,350 feet, Littleton’s semi-arid climate produces exceptionally fine, lightweight dust that stays airborne longer and penetrates deeper into duct systems than in lower, more humid markets. The wildfire smoke season, now routinely May through October, adds distinct fine-particulate loading events multiple times per year.
The housing stock compounds this. Ranch-style homes from the 1950s-1970s near historic downtown often have slab-on-grade foundations with supply and return runs snaking through unconditioned crawl spaces. In Ken Caryl Ranch, technicians regularly encounter original late-1970s and 1980s flexible ductwork that has sagged and kinked at joist hangers, creating low-point pockets where wildfire ash and construction debris pool. These sections frequently need repair or resupport before cleaning can fully clear the line.
Our Main Littleton Services
Most Littleton homeowners who call us need one of these three services:
Air Duct Cleaning in Littleton
We clean the full supply and return network with negative-pressure extraction, agitation, and rotary brushing. In Littleton, we pay particular attention to smoke particulate embedded in older flex duct and galvanized systems. Every run is photographed before and after. Air Duct Cleaning in Littleton includes the full documented photo record as standard.
Dryer Vent Cleaning in Littleton
Lint accumulation accelerates in dry climates, and Littleton’s hard water minerals can cake onto mesh screens, restricting airflow further. We clean the full vent run from appliance to termination, verify airflow with a meter, and photograph the before condition. Dryer Vent Cleaning in Littleton is quoted upfront with a written price.
Duct Repair & Sealing in Littleton
Sagging flex duct, disconnected joints, and rodent damage are common findings in Littleton’s crawl spaces and attics. We resupport, reconnect, or replace sections as needed, then seal with mastic and metal tape. Duct Repair & Sealing in Littleton is documented with photos of every repair.

BeforeAfterHVAC Cleaning in Littleton
HVAC cleaning in Littleton addresses what standard filter changes cannot: fine particulate from wildfire smoke seasons and decades of accumulation in original systems. We clean the full mechanical assembly, not just the ducts, using Rotobrush and Nikro equipment. HVAC Cleaning from CleanRun includes the 365-Day Done Right Promise on every job.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or a musty odor when the AC first cycles on.
What it costs in Littleton
Evaporator coil cleaning typically runs $180-$340 in Littleton.
How we do it
We access the coil through the plenum (the main air distribution box), apply foaming cleaner, 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 across rooms, or dust puffing from registers at startup.
What it costs in Littleton
Blower cleaning typically runs $140-$280 in Littleton.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the assembly, and reinstall with torque verification.
What HVAC Cleaning Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $140-$280 |
| Full HVAC system cleaning | $280-$520 |
How often should HVAC cleaning be done in Littleton?
Every 3-5 years for most Littleton homes, or sooner after heavy wildfire smoke exposure. Homes with original 1970s-1990s ductwork often benefit from more frequent inspection. Call (720) 513-5159 to schedule.
Does HVAC cleaning help with wildfire smoke residue?
Yes, but only when the full mechanical system is addressed, not just the ducts. Smoke particulate embeds in coils, blowers, and plenums where standard filters cannot reach. Our photo record shows what was removed.
Air Quality & Sanitizing in Littleton
Air quality and sanitizing in Littleton targets what remains after mechanical cleaning: microbial growth in humid coil pockets, smoke odor compounds absorbed into porous duct liner, and biological loading in homes with pets or water intrusion history. Air Quality & Sanitizing uses Guardsman and Honeywell products applied with documented coverage verification.
Mold Treatment
Signs you need it
Visible growth near registers, a persistent earthy odor, or recent water intrusion in crawl spaces common in Littleton’s older ranch homes.
What it costs in Littleton
Mold treatment typically runs $220-$450 in Littleton.
How we do it
We apply EPA-registered antimicrobial through the full duct network, fog unconditioned spaces where mold originates, and verify coverage with UV fluorescence inspection.
UV Light Installation
Signs you need it
Repeated microbial growth after cleaning, high allergy symptoms indoors, or a home with chronic humidity control issues.
What it costs in Littleton
UV light installation typically runs $320-$580 in Littleton.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and verify irradiance at the coil surface with a meter.
What Air Quality & Sanitizing Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Mold treatment | $220-$450 |
| UV light installation | $320-$580 |
| Whole-system sanitizing | $180-$360 |
Is sanitizing necessary after wildfire smoke?
Smoke odor compounds bind to porous duct liner and can recirculate for months. Sanitizing breaks these compounds down; we verify results with before-and-after odor assessment. Call (720) 513-5159 for an evaluation.
Are UV lights effective in Littleton’s dry climate?
Yes, because the target is the evaporator coil, not ambient humidity. Coils generate their own moisture during cooling cycles, creating a microclimate where mold grows regardless of outdoor conditions.
