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.

AfterTrusted Air Duct Cleaning for Littleton Homeowners
Air duct cleaning in Littleton typically costs $350-$850 for a complete residential system and takes 2-4 hours from arrival to final photo documentation. CleanRun Duct Repair & Cleaning has served more than 52,000 homes since 2013, and every job starts with a written price delivered before any work begins. Call us at (720) 315-7291 to schedule your free estimate.
Littleton homeowners who bought between 2015 and 2025 are dealing with a specific set of duct conditions. Newer builds in neighborhoods like Roxborough Park and Ken Caryl Ranch often have construction debris still sitting in the plenum, the main distribution box where all duct runs connect. Older homes near downtown Littleton and along the South Platte River corridor show different patterns: rodent activity in crawl spaces, pollen infiltration from the dry Front Range winds, and the fine dust that settles when Chinook winds strip topsoil from the eastern plains. We’ve photographed it all. Our crews operate under the H.A.V.E.N. Standard, with Haven Standard Clause 1 requiring a written price before any panel comes off your system. Tomas Reyes established this practice when CleanRun opened in 2013, and it hasn’t changed.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential duct cleaning covers the complete network of supply and return runs in single-family homes, townhomes, and condos. In Littleton, we most often see homes with 12-20 duct runs, with debris concentrated at the first elbow, the angled fitting where airflow changes direction and particles drop out of suspension. CleanRun’s residential service includes negative-pressure extraction, a process that pulls dislodged debris through a sealed vacuum line so nothing escapes into your living space, followed by a documented photo record of every run. The written scope specifies exactly which registers, the visible vent covers in each room, are included and which, if any, require additional access.
Commercial Duct Cleaning
Commercial duct cleaning addresses the larger-distribution systems found in office buildings, retail spaces, medical clinics, and multi-tenant properties along Littleton Boulevard and in the Aspen Grove commercial corridor. These systems use thicker sheet metal, larger plenums, and often rooftop HVAC units with longer horizontal trunk lines. CleanRun’s commercial crews use Nikro portable HEPA equipment sized for extended duct runs, and every job includes a written scope with line-item pricing for each air handler zone. We schedule commercial work to minimize disruption to your operations, with photo documentation delivered as a standard job record for your facilities file.
Supply Duct Cleaning
Supply duct cleaning targets the runs that deliver conditioned air from your furnace or air handler to each room. In Littleton’s variable climate, where January nights drop below 10°F and July afternoons push 95°F, supply ducts work harder than in milder regions and accumulate more thermal cycling debris. CleanRun’s supply-duct service removes the register, inserts a rotating brush system, typically a Rotobrush unit, to agitate built-up material, and extracts it under negative pressure. The photo record shows the condition at the register opening, at the first elbow, and at the trunk connection, so you can verify the full length was addressed.
Return Duct Cleaning
Return duct cleaning focuses on the larger runs that pull air back to the furnace for reconditioning. These ducts are the entry point for most household contaminants: pet hair, skin cells, cooking particulates, and the fine silty dust that blows through Littleton during spring wind events. Return ducts are often larger and may include a central return grille rather than individual room registers, making them harder to access without proper tools. CleanRun’s return-duct service includes inspection with a borescope camera before agitation, so the technician can locate any structural issues or past rodent activity that would affect the cleaning approach.
Full System Cleaning
Full system cleaning encompasses supply ducts, return ducts, the plenum, the blower compartment, and the evaporator coil if accessible. This is what most Littleton homeowners need when they haven’t had service in 5+ years or are experiencing system-wide dust circulation. CleanRun’s full-system service follows a written sequence: register removal, register cleaning, duct run agitation and extraction, plenum vacuuming, blower compartment inspection, and final photo documentation of every component touched. The price is agreed in writing before work starts, with no per-vent add-ons or surprise charges for “extra dirty” sections.
Video Inspection
Video inspection uses a flexible borescope camera to record the interior condition of duct runs without disassembling the system. In Littleton, we recommend this when a homeowner suspects a specific problem, a persistent odor in one room, visible mold near a register, or airflow that doesn’t match the duct design, but isn’t ready to commit to full cleaning without evidence. CleanRun’s video inspection delivers dated, labeled footage of each run examined, with the technician narrating findings in real time. If cleaning is recommended, the inspection fee is credited toward the service. If the ducts are clean, you have documentation for your records.

Brands We Service for Air Duct Cleaning
CleanRun’s equipment roster includes professional-grade tools from trade-recognized manufacturers. We deploy Nikro portable HEPA extractors on jobs where space is limited or where multiple units are needed for large homes in Highlands Ranch and the broader Littleton service area. These units maintain negative pressure throughout the cleaning cycle, preventing cross-contamination between rooms. Our technicians also use Honeywell media filters and Aprilaire whole-house air cleaners as reference points when advising homeowners on maintenance intervals, since the condition of these installed components often indicates how much debris is moving through the system.
Abatement Technologies supplies our containment and filtration accessories for commercial jobs and remediation-adjacent work. We’ve serviced systems with factory-installed Aprilaire media cabinets, Honeywell electronic air cleaners, and Guardman UV-C installations, and we understand how these components interact with duct cleanliness. Whether your Littleton home has a standard 1-inch filter slot or a 5-inch media cabinet with a Honeywell, Aprilaire, or other recognized brand, we can assess how duct cleaning fits into your overall air quality maintenance. If you have a different make, our process adapts; the tools and the documentation standard remain the same.
BeforeAfterSigns You Need Air Duct Cleaning Right Now
- Visible dust puffing from registers when the system starts. This means debris has accumulated past the point where the blower can keep it settled, and each cycle redistributes particulates into your breathing air. In Littleton’s dry climate, this dust is often finer and more persistent than in humid regions, and it doesn’t take much to create a visible plume.
- Uneven heating or cooling between rooms on the same duct zone. A partially blocked duct run restricts airflow and creates temperature stratification. We’ve found collapsed flex duct, rodent nests, and construction debris completely occluding runs in Littleton homes, especially in crawl space and attic installations where access is limited.
- Persistent musty or stale odors that don’t source to any single room. Ducts can harbor organic material, pet dander accumulation, or moisture-related microbial growth in the evaporator pan or downstream plenum. The smell circulates when the blower runs and dissipates when it stops, which is a reliable indicator of duct-origin contamination.
- Increased dust accumulation on surfaces within 48 hours of cleaning. If you’re dusting more often and the layer returns quickly, your ducts may be acting as a reservoir, releasing stored particulates faster than your filtration can capture them. This pattern is common in Littleton’s newer subdivisions where construction debris was never fully cleared.
- Recent renovation or remodeling without duct protection. Drywall dust, insulation fragments, and sawdust enter open registers during construction and settle in trunk lines. Even “minor” projects generate surprising quantities of fine particulate that standard filters won’t remove once it’s inside the duct network.
Our Air Duct Cleaning Process - Step by Step
- 1
Written price agreement before work begins. Haven Standard Clause 1 requires that every customer receives a written, itemized price before any panel is removed or any tool is powered on. For Littleton air duct cleaning, this means we inspect your accessible ductwork, count your registers, note any access limitations like finished basements or sealed soffits, and deliver a flat price for the complete scope. No per-vent pricing. No “we’ll see how bad it is” estimates.
- 2
Register and grille removal with condition documentation. Each register and return grille is removed, photographed, and cleaned separately. We note corrosion, paint overspray, or physical damage that might affect reinstallation. In Littleton’s older homes near Main Street, we sometimes find original steel registers with decades of accumulated finish; we document before attempting any aggressive cleaning.
- 3
Mechanical agitation and negative-pressure extraction. A rotating brush system, typically Rotobrush equipment sized to the duct diameter, dislodges adhered debris while a Nikro HEPA extractor maintains continuous negative pressure at the point of disturbance. This combination prevents debris from escaping into the living space during cleaning. The technician moves methodically through each run, with the borescope verifying brush contact at elbows and transitions.
- 4
Plenum and air handler compartment cleaning. The plenum, the sheet-metal box where all duct runs converge at the furnace, is vacuumed and wiped. The blower compartment is inspected for debris accumulation on the squirrel cage, which can imbalance the wheel and reduce efficiency. If the evaporator coil is accessible without refrigerant line disturbance, we assess its condition and include light cleaning in the standard scope if appropriate.
- 5
Photo documentation, reassembly, and final walkthrough. Every duct run is photographed after cleaning and matched to its before image. Registers are reinstalled, the system is powered on, and the technician verifies airflow at each location. The complete photo record, labeled by room and run number, is delivered as part of your job documentation. The 365-Day Done Right Promise is activated in writing before the crew departs.
How Much Does Air Duct Cleaning Cost in Littleton?
A typical residential full-system air duct cleaning in Littleton runs $450-$750 for homes with 12-16 duct runs, the most common configuration in neighborhoods like Columbine Valley and Willow Creek. Smaller condos or townhomes with 6-8 runs may fall in the $350-$500 range. Larger homes in Cherry Hills Village or south Littleton with 20+ runs, multiple air handlers, or finished basement access limitations can reach $800-$1,100. Commercial systems are priced per air handler zone, with written line-item scopes.
Several factors move the price within these ranges. Access difficulty matters: crawl space ducts take longer than basement runs. The number of registers is fixed and countable, so there’s no ambiguity there. System configuration affects time: a single central return is faster than multiple bedroom returns. And the condition documented at inspection matters; heavy construction debris or rodent contamination requiring additional containment steps is noted in the written scope with any adjustment to price before work proceeds.
What you should watch for in competitor quotes: per-vent pricing that starts low and multiplies upward, “whole house” quotes that exclude the return side, and teaser rates that don’t include photo documentation or written warranty. CleanRun’s price includes every run, both supply and return, the plenum, the photo record, and the 365-Day Done Right Promise. We also offer a Free Second Opinion on any written estimate: bring us a competitor’s quote, and we’ll put our number next to it with no obligation.

Frequently Asked Questions - Air Duct Cleaning in Littleton
Air duct cleaning is the mechanical removal of accumulated dust, debris, and organic material from the interior surfaces of your HVAC duct network. The process dislodges settled particulates with rotating brushes or compressed air tools and extracts them under negative pressure so they don’t re-enter your home. What comes out varies by house: in Littleton, we commonly find fine silty dust, pollen, pet dander, construction debris in newer homes, and occasionally rodent nesting material in crawl space runs.
A typical residential full-system cleaning takes 2.5 to 4 hours from crew arrival to final walkthrough. Smaller systems or supply-only service may finish in under 2 hours; larger homes with access complications or multiple air handlers can extend to 5 hours. We schedule based on the written scope, not a fixed block, so you’re not charged for idle time or rushed through incomplete work.
Most Littleton homeowners pay $450-$750 for a complete residential system, with smaller homes starting around $350 and complex larger properties reaching $850-$1,100. The exact price depends on register count, system configuration, and access conditions, all of which are assessed and documented in your written estimate before work begins. Call (720) 315-7291 for your specific quote - estimates are free and carry no obligation.
Yes. CleanRun technicians are trained on systems with factory-installed Honeywell electronic air cleaners, Aprilaire media cabinets, and other major-brand components. We don’t service the electronic cells or replace media as a primary service, but we understand how these components integrate with duct cleanliness and can advise on maintenance intervals based on what our inspection reveals. For brand-specific component service, we refer to qualified HVAC contractors and focus on what we do: thorough duct cleaning with documented results.
We do not advertise same-day or emergency dispatch for air duct cleaning. This is a scheduled service requiring proper equipment loading, scope review, and adequate time for thorough work. For urgent situations, property transactions with closing deadlines, or health-related concerns, we maintain a cancellation list and will accommodate if a slot opens. All calls are answered by a live person, 24/7, who can discuss your timeline and find the earliest feasible appointment.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, documented in writing on every invoice. This is not a manager-discretionary policy but a written guarantee under the H.A.V.E.N. Standard. If you observe dust discharge, odor recurrence, or airflow issues within 365 days of service, we return to assess and correct at no charge. The photo record from your original service provides the baseline for any dispute.
Clear a path to your furnace or air handler and to any registers behind furniture. Our crews move light furnishings as needed, but heavy pieces should be shifted in advance if you want those runs fully addressed. Secure pets in a separate area; the equipment noise and door traffic disturb most animals. We’ll need access to a grounded electrical outlet and, for basement furnaces, clear stairway passage. The technician calls 30 minutes before arrival, identified by name, so you know who’s coming.
