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.
Lennox Air Duct Cleaning in Stonegate, CO | CleanRun Air Duct Cleaning Parker
We provide Air Duct Cleaning in Stonegate as independent Lennox service, not manufacturer-authorized work. The one thing that makes our Lennox work here different is the cohort effect: because Stonegate was built as a single master-planned community, entire blocks of homes hit the 20-to-30-year flex-duct failure window simultaneously, and we’ve cleaned enough of them to know exactly which Lennox Merit and Elite Series layouts sag first in these attics. Call (719) 259-4520 for a written estimate before any work starts.
Why Stonegate Residents Choose Us for Lennox Service
Tomas Reyes, our owner and lead technician, grew up in Queens and completed his HVAC training at New York City College of Technology before moving west. He’s spent well over a decade doing duct cleaning work, and his crew knows Stonegate’s housing stock intimately - the same flex-duct configurations, the same Lennox cabinet clearances, the same boot register placements repeating house after house in this master-planned community.
We carry Lennox sales & service parts knowledge but operate independently. That means no OEM markup when a certified equivalent flex duct or mastic will perform identically. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. Every job opens with a written price and closes with a Documented Photo Record of every duct run, before and after. We’ve held that practice since 2013.
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands customers can verify independently. We don’t ask anyone to trust us on reputation alone. “Show the duct first. Talk price second.”
Common Lennox Air Duct Cleaning Problems We Solve in Stonegate

- Sagging flex duct runs off Lennox air handlers in Stonegate attics. The semi-arid Front Range climate produces extreme attic temperature swings, and the low humidity at 5,900-6,200 feet accelerates outer jacket cracking on flex duct. We’ve replaced dozens of these runs in Stonegate homes where the inner liner has collapsed against itself, choking airflow to half the designed CFM.
- Deteriorating inner liner on builder-installed flex duct. Original to the 1990s-2000s Lennox systems common here, the liner sheds fiberglass fibers into supply air once the adhesive binding breaks down. The camera shows it clearly: a fuzzy white coating on the duct wall that wasn’t there at installation.
- Debris-packed boot registers from construction-era leftovers. Stonegate’s rapid Douglas County tract-building meant no standard post-construction duct cleaning protocol. Our techs regularly pull drywall dust, wood shavings, and insulation fragments from Lennox register boots - debris baked on since the early 2000s punch-out.
- Blower wheel imbalance and coil fouling on Lennox air handlers. Chinook winds push fine native soil particulates and, increasingly, wildfire smoke ash through return systems. Because Stonegate’s climate demands nearly year-round heating and cooling operation, these particles accumulate far more run-time hours than in lower-elevation Colorado communities.
- Cracked plenum connections on Lennox Merit Series furnaces. The thermal cycling in unconditioned Stonegate attics separates mastic seals at the air handler plenum. We reseal with fresh mastic and mechanical fasteners, then photograph the repair.

AfterLennox Service in Stonegate: What Local Conditions Mean for Your Equipment
Because Stonegate was platted as a single master-planned community, entire blocks of homes hit the 20-to-30-year flex-duct age threshold at the same time - so when one neighbor schedules a cleaning, often the whole cul-de-sac is dealing with the same collapsing liner and debris-packed boots. This cohort effect is unique to Stonegate’s planned-community origins. In Parker or Castle Rock, where development happened incrementally across decades, you’d see a mix of duct ages and failure modes. Here, it’s remarkably uniform.
On a recent job in Stonegate, our tech pulled a full shop-vac load of drywall dust and wood shavings out of the boot registers feeding a 2001 Lennox Merit furnace - debris that had been sitting there since the home was built. After running video inspection we found three sagging flex runs in the attic with cracked inner liner, which we replaced and sealed with mastic before cleaning the blower and evaporator coil. The homeowner said their system hadn’t moved that much air since move-in.
For Lennox owners, this means predictable problems with predictable solutions. We stock the flex-duct diameters, register boot sizes, and mastic types that match what Lennox systems in Stonegate were built with. No waiting on special orders.
Lennox Models & Products We Service in Stonegate

We work on the full range of Lennox forced-air equipment found in Stonegate’s late-1990s and 2000s housing stock:
- Lennox Merit Series furnaces - the builder-grade workhorse in most Stonegate tract homes, typically paired with basic flex-duct distribution.
- Lennox Elite Series furnaces and air handlers - higher-efficiency units with tighter cabinet clearances that demand precise duct sealing to maintain rated AFUE.
- Lennox Dave Lennox Signature Collection - premium systems where duct leakage directly undermines the variable-speed blower’s efficiency gains.
- Lennox XC and SL series air conditioners paired with matching indoor coils - coil fouling from Front Range particulates is a common issue we address during integrated cleaning.
We use OEM-spec or certified-equivalent flex duct, mastic, and register boots. If a Lennox heat exchanger or air handler cabinet is cracked or rusted beyond safe repair, we say so directly. Most duct-side problems are fixable without replacing the furnace.
Lennox Service Pricing in Stonegate
Whole-system air duct cleaning for Lennox equipment in Stonegate typically runs $420-$680 for a standard single-furnace home with 10-14 registers. Flex duct repair adds $180-$340 per run depending on attic access and length. Video inspection is included at no extra charge on every cleaning job - we don’t sell it as an add-on.
What drives the cost: register count, attic accessibility, and whether we’re cleaning only or also repairing sagging runs and resealing plenum connections. Every price is written and agreed before work starts, per Haven Standard Clause 1. No per-vent pricing, no coupon bait-and-switch.

FAQs - Lennox Air Duct Cleaning in Stonegate
Clean the ducts first. A fouled duct system makes any furnace, new or old, work harder and deliver less. We’ve cleaned original Lennox Merit systems in Stonegate that then performed well enough the owner deferred replacement another three to five years. The camera shows you exactly what’s restricting airflow before you commit to either path. Call (719) 259-4520 to schedule inspection.
No. Lennox does not mandate a particular duct cleaning protocol for warranty purposes, and we are not a Lennox-authorized dealer - we’re an independent service provider. We follow NADCA guidelines for mechanical cleaning and document every step with before-and-after photos. If your system is still under factory warranty, we note our methods in writing so you have a record.
Cottonwood seeds from the mature stands near Fox Run Preserve Park, combined with Chinook winds stirring native soil, overload return systems in April and May. Stonegate’s near-constant HVAC operation year-round means more hours for deposition. We find blower wheels coated with a felt-like mat of seed fluff and fine dust that wasn’t designed into the original system load. A thorough Stonegate Dryer Vent Cleaning with coil and blower service restores designed airflow.
Yes, in most Stonegate homes. The original flex duct runs branch off a hard-pipe trunk line, and we can replace individual sagging or cracked runs from the plenum or trunk tap to the boot register. We use mastic-sealed mechanical connections, not tape, and photograph each joint. Full trunk replacement is rarely needed unless the hard pipe itself is crushed or rusted through.
The camera reveals liner delamination, hidden sags that create debris-collection pockets, and disconnected joints behind finished basement ceilings - problems no brush or vacuum can diagnose. On one Stonegate job, the camera found a fully separated flex duct run blowing conditioned air into an attic corner for fifteen years. The homeowner’s “high utility bills” suddenly made sense. Call (719) 259-4520 to add video inspection to your service.
