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.

AfterLennox Air Duct Cleaning in Littleton, CO | CleanRun Air Duct Cleaning Littleton
Air Duct Cleaning in Littleton for independent Lennox systems typically runs $380-$620 for a complete residential job, depending on whether your home is a historic ranch with original fiberglass-lined ductwork or a Highlands Ranch tract with aging flex duct. We clean the full air path on every Lennox model line, from Merit Series furnaces to Dave Lennox Signature Collection systems, and we photograph every duct run before and after so you see what changed. Call (720) 315-7291 for a written price before any work starts.
Why Littleton Residents Choose Us for Lennox Service
We’ve cleaned ductwork on thousands of Lennox systems across Littleton since 2013. Our techs know the cabinet layouts, coil configurations, and plenum designs specific to Lennox Merit, Elite, and Signature Series furnaces, so we don’t disturb factory components or create warranty complications for homeowners who still hold coverage.
Tomas Reyes, our owner, grew up in the Bronx and learned his trade fundamentals at BOCES Suffolk before heading west. He’s been running jobs in Littleton for years, including plenty of work in the Columbine Knolls neighborhoods where older homes carry duct liners that tell a longer story than the listing price suggests. Tomas pulls the inspection camera before quoting anything, then walks homeowners through exactly what the footage shows - debris load, flex duct condition, register seal gaps - in plain terms, not sales language. He keeps a printed price sheet in his truck because he got tired of customers wondering whether the number changes based on who answers the phone.
We stock Lennox-compatible aftermarket filters, flex duct, mastic, and sealing components where they meet or exceed OEM spec. For blower wheels, coils, and control-specific items, we use genuine Lennox parts when a system still warrants the investment. We tell customers honestly when a furnace or coil is at end of life versus when cleaning and sealing will restore performance for years. Every job carries a written price before work begins, a Documented Photo Record of every duct run, and our 365-Day Done Right Promise backed in writing.
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands customers can verify independently. All technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
Common Lennox Air Duct Cleaning Problems We Solve in Littleton
- Cased coil loading from Front Range dust and wildfire smoke. Lennox A-frame coils in the Dave Lennox Signature Collection and Elite Series have tight fin spacing that traps fine particulate. In Littleton’s semi-arid climate at 5,360 feet, Chinook winds push dust through home envelopes continuously, and increasingly severe wildfire smoke seasons pull odor into ductwork that recirculates until cleaned. We see restricted airflow and wet, dirty coil faces that must be addressed before any duct sealing.
- Return flex collapse in Highlands Ranch tract homes. Lennox downflow and horizontal furnaces common in 1990s-2005 Highlands Ranch builds pull return air through builder-grade flex duct that has sagged, kinked, or torn after 25-35 years. The blower runs dirty and starves the coil. In 80126 and 80130 zip codes, identical layouts across adjacent homes mean when one system shows this failure, neighbors typically share it.
- Fiberglass liner degradation in historic Littleton ranches. Original Lennox supply trunks in 1950s-1970s homes near downtown have fiberglass lining that sheds fibers into the airstream. Vacuuming alone won’t stop it; the liner must be removed or encapsulated. We document the condition with camera footage before recommending either approach.
- Variable-speed blower motor strain from dust loading. Lennox variable-speed motors in Signature and Elite furnaces draw heavy amperage when the blower wheel is caked with dust. Homeowners sometimes replace a healthy motor when cleaning the wheel and evaporator coil would restore normal draw. We measure amp draw before and after to show the difference.
- Smoke odor persistence in post-wildfire seasons. Once wildfire smoke particulate enters a Lennox system’s ductwork, standard filter changes won’t remove it. The odor recirculates through the supply plenum until negative-pressure extraction and coil cleaning pull the residue out. We see this annually in Littleton now, not as an exception.
BeforeAfterLennox Service in Littleton: What Local Conditions Mean for Your Equipment
Littleton’s housing market creates an unusual concentration of aging ductwork that no neighboring suburb replicates at this scale. The historic core holds compact 1950s-1970s ranch homes with original galvanized or fiberglass-lined ductwork growing increasingly brittle. Meanwhile, the vast Highlands Ranch subdivisions - despite carrying Littleton mailing addresses across 80126, 80129, and 80130 - contain dense tracts of 1990s-2005 builder-grade homes whose original flex duct is now sagging, punctured, or loaded with debris. For Lennox owners, this means two completely different failure patterns depending on which side of the city you’re on.
The synchronized construction in Highlands Ranch creates something we haven’t seen elsewhere. Cul-de-sacs in 80126 and 80130 were built by the same crews in the same years, so adjacent Lennox systems often share identical flex-duct layouts, identical sag points, and identical debris loads at the same age. A duct cleaning route in those zip codes frequently turns into a block-wide pattern, not a one-house anomaly. In a 1998 Highlands Ranch cul-de-sac off Wildcat Reserve Parkway, we cleaned a Lennox Elite EL296V system whose return flex had collapsed at two elbows, dumping dust straight onto the cased coil. Our tech pulled the blower, cleaned the wheel and coil, replaced the crushed flex runs, and mastic-sealed the plenum; the homeowner’s static pressure dropped and the upstairs rooms finally held temperature. We also checked the Littleton Dryer Vent Cleaning needs while on site, since adjacent homes in these 1990s builds often share identical venting risks too. Three doors down, the identical builder-grade layout had the same failure at the same age. The camera doesn’t negotiate - it just shows what’s there.

FAQs - Lennox Air Duct Cleaning in Littleton
No. Duct cleaning performed by a qualified technician does not void a Lennox factory warranty. We are an independent service provider, not a Lennox-authorized dealer, and we document our methods so any warranty claim remains clean. We do not modify factory wiring, control boards, or safety limits during cleaning. If your system is still under warranty, we’ll note the coverage in your job record and work accordingly.
It depends on what the camera shows. Fiberglass liner that is intact and adhered can sometimes be cleaned and encapsulated. Liner that is shedding, delaminated, or water-damaged needs removal or full duct replacement. We photograph the condition and quote both options in writing before any work starts. Many historic Littleton ranches near downtown have ductwork from the 1960s that is now at end of life; we’ll say so directly if that’s what we find.
Wildfire smoke particulate enters your return ductwork, deposits on the evaporator coil and blower wheel, and recirculates whenever the fan runs. Standard filters don’t capture the odor-bearing particles. The smell persists until the full air path - ducts, coil, and blower - is cleaned with negative-pressure extraction and coil treatment. In Littleton’s increasingly severe smoke seasons, this is now an annual maintenance consideration for many homeowners, not a one-time fix.
We measure static pressure across the coil and inspect the fins with a borescope. If pressure drop returns to spec after cleaning and the fins are structurally sound, cleaning is sufficient. If the coil is corroded, leaking, or the fins are deteriorated to the point that cleaning won’t restore heat transfer, we’ll show you the footage and quote replacement. We don’t sell coils to solve a dirt problem. Call (720) 315-7291 for an inspection and written assessment.
Yes. While we specialize in Lennox configurations, our technicians carry equipment and parts for all major residential brands. If your home has a Lennox furnace paired with a different-brand air handler, or multiple systems across the property, we clean and document everything in one visit with one written price.
