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.
How Much Does HVAC Cleaning Cost in Littleton?
HVAC Cleaning services in Littleton, CO typically cost between $320 and $780 for a standard single-family home, depending on system size, duct count, and how long it’s been since the last cleaning. Most Littleton homes we service fall in the $400-$600 range – that covers a full negative-pressure extraction of all duct runs, a documented photo record of every register before and after, and a written price delivered before any panel comes off. At CleanRun, every job includes that written price upfront and the 365-Day Done Right Promise in writing – not as a policy subject to manager approval, but as a documented commitment.
HVAC Cleaning Cost Breakdown (2026)
These are the actual line-item ranges we quote in the Littleton market. Every number below reflects what we put in writing before work starts, under Haven Standard Clause 1.
| Service Component | Typical Price Range (Littleton, 2026) | Notes |
|---|---|---|
| Standard air duct cleaning (supply + return runs) | $320 – $520 | Covers homes with 8-15 duct runs; negative-pressure extraction with Nikro or Rotobrush equipment |
| Large home duct cleaning (16+ runs) | $520 – $780 | Common in Littleton’s larger footprint homes in Ken Caryl Ranch and Columbine Valley areas |
| Dryer vent cleaning (added to HVAC job) | $89 – $149 | Priced separately; often bundled; access from roof adds to cost |
| Furnace/air handler compartment cleaning | $75 – $140 | Includes blower wheel, evaporator coil access area, and plenum – the central chamber where conditioned air collects before distribution |
| Sanitizing treatment (EPA-registered) | $95 – $180 | Applied post-extraction using Abatement Technologies-compatible foggers; recommended after mold findings or pet occupancy |
| Duct sealing (Aeroseal or mastic, per zone) | $400 – $950 | Quoted separately after camera inspection; common in Littleton homes built before 1995 |
| Full HVAC cleaning package (ducts + furnace compartment + dryer vent) | $499 – $850 | Most common complete-service quote for Littleton single-family homes |
What the Price Actually Covers
When CleanRun quotes $450 for a duct cleaning job in Littleton, here is exactly what that price includes: a technician who arrives uniformed and identified by name before entering the home (Haven Standard Clause 3: Verified Crews), professional-grade negative-pressure extraction using Rotobrush or Nikro equipment, photographs of the interior of every duct run before and after the work, a written scope delivered before any work begins, and the 365-Day Done Right Promise on the finished job. The photo record is not optional or an upsell – it is part of the standard deliverable on every CleanRun job, the same practice we have followed since our first job in 2013.
What it does not include: a technician walking through your home with a shop vac and calling it done. That is what the $79 coupon jobs look like from the inside. The camera documentation makes the difference visible – and verifiable.
Why Littleton Pricing Runs Slightly Higher Than Some Denver Suburbs
A few local factors consistently push prices in Littleton toward the middle and upper end of the metro range. First, the soil. Littleton and the surrounding Arapahoe and Jefferson County areas sit in a high-plains semi-arid zone where fine particulate – clay dust, pollen from the cottonwood corridors along the South Platte – works its way into duct systems faster than in wetter climates. Homes near Chatfield Reservoir or along the Mineral Avenue corridor regularly show thicker debris builds than comparable-age homes in higher-humidity Denver neighborhoods. That means more extraction time per run, which means honest pricing reflects more labor.
Second, housing stock. A substantial portion of Littleton’s single-family homes were built between 1975 and 1995 – the flex-duct-and-fiberglass-liner era. Those systems require more careful extraction to avoid liner damage and frequently reveal debris compaction at elbows that newer rigid-metal systems don’t. The camera finds it. The written price reflects it.
What Affects HVAC Cleaning Pricing in Littleton

- Number of duct runs and registers: This is the primary cost driver. A 1,400 sq ft townhome in downtown Littleton might have 9 supply registers and 3 returns. A 3,200 sq ft two-story in Columbine Valley could have 22 supply runs and 6 return chases. Each run is photographed and extracted individually, so run count directly affects time and therefore price.
- Duct material and age: Rigid sheet metal ducts clean faster and tolerate more aggressive extraction than older flex duct or fiberglass-lined systems. Homes in Littleton built before 1990 disproportionately have older duct materials that require slower, more careful work. The camera inspection before quoting identifies this – and the written price reflects it before work starts, not after.
- Access difficulty: Duct runs that travel through finished basement ceilings, crawlspaces common in older Littleton ranch-styles, or tight attic chases take longer to reach. Homes in the Columbine and Bow Mar neighborhoods often have this configuration. Access difficulty is assessed at the inspection and written into the quote.
- System contamination level: The Rotobrush camera tells us what’s actually in there before we price the job. A duct run showing a 2-inch compacted debris layer at the first elbow off the plenum takes more extraction passes than a lightly dusty system. Littleton homes that have gone 8-10 years without cleaning – or that have never been cleaned since construction – typically fall in the upper third of the price range for their system size.
- Presence of pets, recent renovation, or moisture: Dog and cat dander compacts differently than construction dust – it mats against liner surfaces and requires more aggressive agitation. Post-renovation cleaning, which we see frequently in the Governors Ranch and Heritage Hills areas, involves drywall particulate that settles deep into supply runs. Moisture or mold findings trigger a separate sanitizing quote.
- Seasonal demand in Littleton: October through December, when homeowners are switching from cooling to heating season and discovering dust blowing from registers, is our highest-demand window in the Littleton market. Scheduling 4-6 weeks outside that window – late January through March, or June through August – typically means faster availability and no surge conditions.

AfterThe $79 Coupon Problem – What It Costs You in Littleton
This section exists because Littleton homeowners ask about it directly, and the honest answer is more useful than pretending the low-cost offers don’t exist.
The $79 duct cleaning coupon that circulates through Littleton area mailers and deal sites represents a specific business model: a technician arrives with a portable shop vac, accesses two or three registers, creates audible suction noise, and leaves. No camera. No negative-pressure extraction that creates a sealed pressure differential across the entire duct system – a technique called source-removal method cleaning, where a large collection unit is attached to the main trunk and all debris is mechanically dislodged toward it. No photo record. No documentation of what was inside the ducts before or after. Often, an on-site upsell to a “full cleaning” at a price well above what a complete, documented job would have cost from the start.
We have photographed the inside of duct systems in Littleton homes immediately after a low-cost cleaning was performed by another company. The camera showed debris still present at the first elbow because the shop vac suction did not reach that far. That photograph – which we show to the homeowner before quoting our work – is the clearest explanation of what a written price and a photo record actually protect you from.
CleanRun’s HVAC Cleaning in Littleton service includes the photo record as a standard deliverable. Not an option. Not an upsell. Every run, before and after, delivered to you as part of the job.
How to Save on HVAC Cleaning in Littleton

Bundle Services on the Same Visit
Dryer vent cleaning, furnace compartment cleaning, and air duct cleaning all share the same setup cost – the truck, the equipment staging, the technician’s travel time. When you schedule all three together, the per-service cost drops because that fixed overhead is spread across more work. For a typical Littleton home, bundling dryer vent cleaning with a full duct cleaning job saves between $60 and $110 compared to scheduling each separately.
Get a Free Second Opinion Before You Commit
If you have a written estimate from another company, CleanRun puts its own number next to it in writing – at no cost. This is not a sales call. It is a literal line-by-line comparison of what each quote covers. Bring the other company’s written estimate to (720) 315-7291 and we will tell you exactly what our price is for the same scope. If the other quote is genuinely better for comparable documented work, we will tell you that too. The free second opinion is available to any Littleton homeowner with a written estimate in hand.
Schedule Outside Peak Season
In Littleton, the highest-demand windows for HVAC cleaning are October through December (heating season startup) and late April through May (cooling season preparation). Scheduling in February, March, or July typically means faster scheduling with no demand-driven delays. The price itself does not change by season – CleanRun does not use surge pricing – but your choice of appointment windows is wider outside those peaks.
Know What You’re Buying Before Anyone Arrives
The single most effective way to avoid overpaying for HVAC cleaning in Littleton is to ask for a written price before anyone starts work. Haven Standard Clause 1 is non-negotiable at CleanRun: a written price is delivered before any work begins, every time, with no exceptions. If a company will not give you a written price before opening your duct system, that is relevant information about how the rest of the job will go.
Call (720) 315-7291 to get a written estimate for your Littleton home – square footage, duct count, and system age are the main inputs, and we can give you a number in the first conversation.
What the CleanRun Process Actually Looks Like – Start to Finish
Understanding the process helps you evaluate any quote you receive, including ours.
A CleanRun technician arrives at your Littleton home at the scheduled time, uniformed and identified by name in advance. The first step is a camera inspection of the main trunk line – the large central duct that feeds the branch runs – and representative supply runs to document baseline conditions. You see the photos before anything else happens.
The written scope and price are delivered based on what the camera found. If the inspection shows 14 supply runs with moderate debris and a furnace compartment with blower wheel buildup, the quote reflects exactly that scope. No surprise add-ons after work begins.
Once you approve the written price, negative-pressure extraction begins. A Nikro or Rotobrush collection unit is connected to the main trunk – the plenum side – creating a controlled pressure differential across the entire duct system. A technician works each supply and return run in sequence, using rotary brush agitation to dislodge debris toward the collection unit. Every run is photographed after extraction.
If sanitizing was included in the scope, it is applied after extraction using Abatement Technologies-compatible fogging equipment, with EPA-registered solution appropriate for residential duct systems. The blower is run briefly to distribute treatment through the system.
At the end of the job, you receive the documented photo record – every run, before and after – as a standard deliverable. The 365-Day Done Right Promise is in writing on the job record. If anything is not right within 365 days, CleanRun makes it right.
HVAC Cleaning vs. Air Duct Cleaning – Are They the Same Thing?

In Littleton, homeowners use “HVAC cleaning” and “air duct cleaning” interchangeably, and most of the time they are describing the same core service: extracting accumulated debris from the supply and return duct network that distributes conditioned air through the home. But there is a meaningful difference in scope worth understanding before you request a quote.
Air duct cleaning, strictly defined, covers the duct runs themselves – the metal or flex passages from the air handler to each register. HVAC cleaning in its full sense extends into the mechanical components: the air handler or furnace compartment, the blower wheel (the fan that moves air through the system), the evaporator coil access area (the heat-exchange surface where dust buildup directly reduces efficiency), and the plenum – the transition chamber between the air handler and the main duct trunk.
When CleanRun quotes HVAC cleaning for a Littleton home, the written scope specifies exactly which components are covered. If the quote covers only duct runs, it says so. If it includes the furnace compartment and blower wheel, that is in the scope. The written price covers what the written scope describes. Nothing more, nothing less, and no revision after work begins.
You can learn more about what the full service includes on our HVAC Cleaning in Littleton page, which walks through each component in detail.
How Often Should Littleton Homes Have HVAC Cleaning Done?
The EPA and NADCA both cite a general guideline of every 3-5 years for residential duct systems under normal occupancy conditions. In Littleton specifically, a few factors push toward the shorter end of that range for many homes.
The Front Range climate delivers distinct spring wind events – the kind that push fine clay particulate through weatherstripping and window seals – followed by extended dry summers where HVAC systems run for months without significant moisture to suppress dust suspension. Homes near Chatfield State Park or in the South Suburban corridor near C-470 see higher ambient particulate loads than the general guideline assumes. Homes with dogs or cats, or homes that have undergone remodeling, should plan on cleaning closer to every 2-3 years.
Older systems in Littleton’s pre-1995 housing stock also tend to accumulate debris faster because the flex duct and fiberglass-liner configurations used in that era have more surface texture for particles to adhere to than smooth-walled rigid metal. When the camera shows a 1.5-inch debris layer at the first elbow after 3 years, that is the duct material, not neglect.
FAQs – HVAC Cleaning Cost in Littleton

How much does HVAC cleaning cost in Littleton, CO?
HVAC cleaning in Littleton costs between $320 and $780 for most single-family homes in 2026, with the majority of jobs falling in the $400-$600 range. That range covers full negative-pressure extraction of all duct runs, furnace compartment access, and a documented photo record of every run before and after. Larger homes in neighborhoods like Ken Caryl Ranch or Columbine Valley with 16 or more duct runs typically fall toward the upper end. A written price is available before any work starts – call (720) 315-7291 for a specific number for your home’s configuration.
Is a $79 duct cleaning deal worth it in Littleton?
No. The $79 price point in the Littleton market consistently represents a shop-vac operation: audible suction at a few registers, no camera documentation, no negative-pressure extraction across the full duct system, and frequently an on-site upsell to a full cleaning at a price higher than what a documented job would have cost. CleanRun has photographed Littleton duct systems immediately after low-cost cleanings were completed by other companies; the camera showed debris still present at the first elbow because the suction never reached it. A written price, a photo record, and a documented guarantee are the baseline for real work – and they are priced accordingly in the $320-$780 range above.
Does HVAC cleaning actually improve air quality in Littleton homes?
Yes, in measurable terms – though the degree depends on baseline contamination. The Littleton area’s semi-arid Front Range climate means duct systems accumulate fine clay particulate, cottonwood pollen, and soil-based particles at higher rates than homes in more humid climates. When the camera shows a 2-3 inch debris build at the first elbow off the plenum – which is common in Littleton homes that have gone 6 or more years without cleaning – that material circulates every time the blower runs. Negative-pressure source-removal cleaning removes it. The before-and-after photo record shows the difference between what was there and what is not. That is the documentation; the air quality improvement follows from it.
Can I get HVAC cleaning and dryer vent cleaning done on the same visit in Littleton?
Yes, and bundling both on one visit typically saves $60-$110 compared to scheduling them separately, because the fixed setup costs are shared. For Littleton homes where the dryer vent exits through the roof – a common configuration in older ranch-style homes in the Bemis Heights and Governor’s Ranch areas – the roof access adds $30-$60 to the dryer vent portion. That is reflected in the written price before the technician goes up. Call (720) 315-7291 and tell us your home’s square footage, approximate duct count if known, and whether the dryer vent exits through the roof or an exterior wall – we can give you a written range in the first conversation.
How long does HVAC cleaning take for a typical Littleton home?
A standard Littleton home with 10-15 duct runs takes 2.5 to 4 hours for a complete documented cleaning. Larger homes in the 16-22 run range run 4-6 hours. The variation comes from duct count, access difficulty, and baseline contamination level – a heavily loaded system takes more extraction passes per run. The photo documentation adds time to each run, because each run is photographed before extraction begins and again after. That time is built into the quoted price. You are not paying separately for documentation – it is part of what the price covers.
Key Takeaways
- HVAC cleaning in Littleton, CO costs $320-$780 for most single-family homes in 2026, with most jobs falling in the $400-$600 range.
- The primary cost drivers are duct run count, duct material and age, access difficulty, and contamination level – all of which are assessed before the written price is delivered.
- Littleton-specific factors – Front Range particulate loads, pre-1995 flex duct systems, and seasonal wind events – push cleaning frequency toward the shorter end of the 3-5 year general guideline for many homes.
- Every CleanRun job includes a written price before work starts, a documented photo record of every duct run, and the 365-Day Done Right Promise – in writing, on every job.
- The $79 coupon model does not represent real HVAC cleaning. Camera documentation and negative-pressure extraction are the difference between verified work and vacuum noise.
- Bundling dryer vent cleaning with HVAC cleaning saves $60-$110 on a single visit. Scheduling outside October-December and April-May gives wider appointment availability.
- A free second opinion on any written estimate is available at no cost – call (720) 315-7291 with the other company’s written quote in hand.
