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
HVAC cleaning in Littleton typically runs $380-$620 for a full system, with most jobs scheduled within a week and completed in a single visit. The combination of 1950s ranch-era fiberglass-lined ductwork in historic Littleton and the massive wave of aging flex-duct systems in Highlands Ranch subdivisions creates a unique local demand for documented, thorough cleaning rather than coupon-grade vacuum passes. Call (720) 315-7291 and we’ll deliver a written price before any work starts.
CleanRun crews coordinate dispatch from our Denver office and serve Littleton homes directly. Every visit includes a Documented Photo Record of every duct run, before and after, as part of the standard job record. That’s been our practice since 2013.
Why Littleton Homes Are Different
Littleton sits at roughly 5,360 feet on the semi-arid Front Range, where Chinook winds off the Rocky Mountain foothills push fine particulate dust through home envelopes year-round. Low humidity keeps that dust airborne rather than settling, so it circulates through HVAC systems continuously.
The housing stock splits into two distinct pressure zones. Historic Littleton proper, neighborhoods like Old Littleton and the streets near Main Street, holds compact 1950s-1970s ranch homes with original fiberglass-lined sheet-metal ductwork that is now brittle, degrading, and often heavily contaminated after 50-70 years of use. Meanwhile, the vast Highlands Ranch development, where zip codes 80126, 80129, and 80130 all carry Littleton mailing addresses, contains thousands of 1990s-early 2000s tract homes whose builder-grade flex-duct systems are simultaneously hitting the 25-35-year mark. Technicians working Highlands Ranch cul-de-sacs routinely find identical flex-duct layouts across adjacent homes installed by the same crews in the same year. When one system is inspected and found full of debris, every neighbor on the street has the identical problem at the same age. No neighboring suburb replicates this concentrated wave at this scale.
Wildfire smoke seasons have grown increasingly severe across the metro area. Once smoke odor is pulled into ductwork, it recirculates until the system is properly cleaned.
Our Main Littleton Services
Littleton homeowners call us most often for these three services:
Air Duct Cleaning in Littleton
We clean the full duct network, from the plenum, the main distribution box, through every duct run, the individual supply and return lines, to each register, the visible vent cover. In Littleton’s older ranch homes we often find degraded fiberglass lining that has begun to shed particles into the airflow. In Highlands Ranch flex-duct systems we document sagging runs and accumulated debris at the low points. Every job ends with a photo record of every run. Air Duct Cleaning in Littleton is scheduled as a flat-price system clean, never per-vent.
Dryer Vent Cleaning in Littleton
Dryer vent blockages are a genuine fire hazard, and Littleton’s dry climate means lint buildup is especially combustible. We clean the full vent path from the back of the dryer to the exterior termination, using rotary brushes and negative-pressure extraction, suction that pulls debris out rather than pushing it deeper. The work is photographed before and after. Dryer Vent Cleaning in Littleton is quoted as a flat price before we start.
Duct Repair & Sealing in Littleton
When ductwork is too damaged for cleaning alone, we repair or replace sections. In historic Littleton homes we seal leaks in aging sheet metal and replace degraded fiberglass lining. In Highlands Ranch we address punctured or sagging flex duct. Every repair scope is written and priced before work begins. Duct Repair & Sealing in Littleton includes the same photo documentation as our cleaning work.

BeforeAfterHVAC Cleaning in Littleton
HVAC cleaning in Littleton addresses the full mechanical system, not just the ducts. The city’s elevation and dry winds mean coils and blowers accumulate fine dust faster than at lower, more humid elevations. In Highlands Ranch homes with identical builder-grade systems now aging out simultaneously, we see blower wheels caked with debris and evaporator coils restricted by dust that has bypassed clogged filters for years. HVAC Cleaning from CleanRun includes every component in the air path, photographed before and after, with a written flat price agreed before any panel comes off.
Evaporator Coil Cleaning
Signs you need it
Weak airflow from registers, ice formation on the coil cabinet, or cooling bills that rise without thermostat changes.
What it costs in Littleton
Evaporator coil cleaning in Littleton typically runs $180-$320.
How we do it
We access the coil through the plenum, apply foaming cleaner, then rinse with low-pressure water and document the before and after with photos.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling between rooms, or dust puffing from registers when the system cycles on.
What it costs in Littleton
Blower cleaning in Littleton typically runs $160-$280.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and contact cleaner, balance the assembly, and photograph every stage.
What HVAC Cleaning Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Full HVAC system cleaning | $380-$620 |
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $160-$280 |
How do I know my HVAC system needs cleaning, not just the ducts?
If rooms heat or cool unevenly, the blower makes noise, or your energy bills climb despite normal usage, the mechanical components are likely restricted by debris. Call (720) 315-7291 for a free estimate and we’ll inspect the full system.
Can HVAC cleaning fix wildfire smoke odor in my Littleton home?
Cleaning the coils, blower, and ductwork removes smoke particles that have settled in the system, but persistent odor may also require sanitizing treatment. We’ll photograph what we find and quote both options in writing.
Air Quality & Sanitizing in Littleton
Air quality and sanitizing in Littleton addresses what cleaning alone cannot remove: live microbial growth, persistent odor, and biological contaminants. The combination of dry, dusty conditions and decades-old ductwork in both historic Littleton and Highlands Ranch creates environments where mold and bacteria can establish in areas of moisture accumulation, around coils and in low spots of sagging flex duct. Wildfire smoke seasons add another layer, embedding odor compounds deep in porous duct lining that recirculates whenever the system runs. Air Quality & Sanitizing from CleanRun uses application-specific treatments, each chosen after inspection and documented with before and after photos.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible growth near registers, or family members with unexplained respiratory symptoms that worsen at home.
What it costs in Littleton
Mold treatment in Littleton typically runs $280-$450 per affected zone.
How we do it
We apply an EPA-registered fungistatic agent to affected duct runs and the plenum, then verify with post-treatment photos and air sampling if requested.
Odor Removal
Signs you need it
Persistent smoke, pet, or cooking odors that return within hours of standard cleaning, or new odors after wildfire season.
What it costs in Littleton
Odor removal treatment in Littleton typically runs $220-$380 for a full system.
How we do it
We fog a neutralizing agent throughout the duct network using a commercial atomizer, then run the system to distribute and verify elimination with post-treatment inspection.
What Air Quality & Sanitizing Costs in Littleton
| Item | Typical range in Littleton |
|---|---|
| Mold treatment (per zone) | $280-$450 |
| Odor removal (full system) | $220-$380 |
| UV light installation | $340-$520 |
Is mold treatment safe for my family and pets?
We use EPA-registered products applied with the home unoccupied, then ventilate the system before occupants return. The treatment is fully documented with photos and product data sheets provided as part of the job record.
Will odor removal eliminate wildfire smoke smell permanently?
If the source is removed and the ductwork is properly treated, yes. If new smoke continues to enter the home during active fire season, the odor may return until outdoor air quality improves. Call (720) 315-7291 and we’ll assess whether your system needs cleaning, treatment, or both.
