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.

Our crew knows the difference between a Merit series plenum and a Signature Collection cabinet, and we carry OEM-compatible Lennox gaskets and transition hardware on our Greenwood Village trucks. Call (720) 799-2292 for a written estimate before any work starts.
Why Greenwood Village Residents Choose Us for Lennox Service
Tomas Reyes, our owner, learned ductwork at Apex Technical School in Manhattan and spent years in Queens apartment buildings before bringing that Northeast thoroughness to Denver. He and our crew have been in Greenwood Village homes for over a decade, including jobs in the Capitol Hill-adjacent neighborhoods where original galvanized runs and aging furnace systems keep the work honest. That background matters here because Greenwood Village’s 1975-1995 Tech Center-era housing stock presents duct geometries we have seen before - long multi-story trunk lines, finished basements with buried returns, and the kind of fiberglass-lined metal work that punishes careless technique.
We are not a Lennox dealer. We are an independent service company that happens to know Lennox cabinet geometry, coil placement, and plenum transitions well enough to clean them without damaging communicating controls or variable-speed blower assemblies. Our Lennox sales & service page details the full scope of what we handle. Every Greenwood Village job starts with a written price under Haven Standard Clause 1, proceeds with a video inspection you watch with us, and ends with a Documented Photo Record of every duct run - before and after - delivered as a standard job record. Our 365-Day Done Right Promise is backed in writing, not subject to manager approval. Here is what the camera found. Here is what it costs to fix it. You decide.
Common Lennox Air Duct Cleaning Problems We Solve in Greenwood Village
- Fiberglass liner degradation in original Tech Center-era trunks. Greenwood Village homes built during the 1975-1995 boom often have Lennox systems paired with fiberglass-lined metal trunk lines. The liner deteriorates with age, and aggressive brushing dislodges fibers directly into the living space. We run controlled negative-pressure extraction with soft tooling so the liner stays put while the debris comes out.
- Blower wheel choking from horse-lot return contamination. Greenwood Village’s preserved horse-keeping ordinance means ground-level returns on these properties pull hay chaff, equine dander, and sandy paddock grit straight into the Lennox blower wheel and secondary heat exchanger face. Owners call us thinking the furnace is failing. Usually it is breathing through a clogged wheel.
- Flex duct collar cracking at altitude. At roughly 5,600 feet, Greenwood Village’s chronically low humidity dries out mastic and cracks flex duct collars at Lennox plenum takeoffs faster than in lower-elevation markets. Return-side leaks pull unconditioned attic air and, increasingly, wildfire ash particulate directly into the system.
- Hidden evaporator coil blockage in communicating systems. Lennox XC/XP condensing units with matching indoor coils can trip high-limit or pressure faults when the coil is partially blocked behind an inaccessible cabinet panel. The board is fine. The coil needs cleaning, and the panel needs to come off properly without breaking OEM gaskets.
- Static pressure loss from long multi-zone duct runs. Greenwood Village’s 3,500-8,000+ square foot homes with finished basements have duct runs far longer and more branched than tract-home suburbs. A Lennox Elite variable-speed blower working against compacted returns cannot maintain design static pressure. Cleaning the full return path, not just the supply, is what restores register airflow.
BeforeAfterLennox Service in Greenwood Village: What Local Conditions Mean for Your Equipment
Greenwood Village’s executive housing stock presents a contamination profile that simply does not appear in neighboring Centennial or Lone Tree. The city’s longstanding residential horse-keeping ordinance, preserved since incorporation, means a meaningful share of our Lennox service calls come from homes off Orchard Road and similar horse-permitted lots where ground-level return trunks are packed with hay chaff, equine dander, and sandy paddock grit. This debris is denser and more fibrous than typical household dust. It compacts in the first elbow of the return trunk and chokes the blower wheel until the Lennox system throws airflow faults or the homeowner notices weak second-floor registers.
Our technicians learn to quote extra time on these Greenwood Village jobs because the material does not respond to standard vacuum pressure alone. We run video inspection first to locate the compaction point, then apply negative-pressure extraction with agitation tools selected for fibrous density. The fiberglass-lined metal trunks common in 1980s Lennox installations here require additional care - too much vacuum pull and the deteriorating liner lifts; too little and the hay chaff stays put. This is the Greenwood Village-specific knowledge that separates actual duct cleaning from shop-vac noise.
We serve the full Greenwood Village service area, from the Tech Center-adjacent neighborhoods to the horse-permitted lots east of I-25.
Lennox Models & Products We Service in Greenwood Village
Our Greenwood Village crews work on the full Lennox residential lineup: Elite series gas furnaces (EL/ELD and older G-series units still common in 1980s Tech Center-era homes); Dave Lennox Signature Collection variable-speed communicating furnaces with their proprietary control boards; Merit series air handlers and furnaces; and XC/XP series condensing units paired with matching indoor coils. We stock OEM Lennox gaskets, cabinet hardware, and transition pieces where fitment matters - a Signature Collection plenum gasket is not interchangeable with generic material - and use quality aftermarket flex, mastic, and insulated ducting where it performs identically for less. Our equipment roster includes Rotobrush, Nikro, and Abatement Technologies cleaning systems; Honeywell, Aprilaire, and Guardsman air quality components. You can look up every brand yourself before we arrive.
Lennox Service Pricing in Greenwood Village
Whole-system Lennox air duct cleaning in Greenwood Village ranges from $480 for a compact Merit-series system in a smaller home to $1,200 for large multi-zone Signature or Elite installations with finished basements, buried returns, or horse-lot contamination requiring extended cleaning time. This is one flat price per system, agreed in writing before any panel comes off. No per-vent pricing. No $79 coupon that becomes $800 on the invoice.
What drives the cost: square footage, number of HVAC zones, accessibility of the plenum and main trunk, and whether video inspection reveals the dense fibrous contamination typical of Greenwood Village horse properties. Every estimate includes the video inspection, the full negative-pressure cleaning of all supply and return runs, evaporator coil cleaning if accessible, and the Documented Photo Record delivered as a standard job record. Call (720) 799-2292 for a written quote - estimates are free, and Haven Standard Clause 1 requires the price in your hand before work starts.

FAQs - Lennox Air Duct Cleaning in Greenwood Village
It is almost always organic debris - hay chaff, equine dander, and paddock grit - compacted in the return trunk and breaking down on the blower wheel or in the plenum, which is why Greenwood Village Dryer Vent Cleaning alone won’t solve the odor. The smell releases when the blower disturbs the material. We see this specifically on Greenwood Village horse-permitted lots, where ground-level returns pull stable-area air directly into the system. Video inspection locates the source, negative-pressure extraction removes it, and cleaning the blower wheel separately eliminates the odor. Call (720) 799-2292 for a written estimate - we will scope it first so you see what we are quoting.
Yes, but only with controlled technique. The fiberglass liner in Greenwood Village’s Tech Center-era homes is typically 40-plus years old and fragile. We run negative-pressure extraction at reduced vacuum with soft agitation tools - brushes that contact the debris without scraping the liner surface. Aggressive rotary brushing or high-pressure air whips will shred the liner and blow fiberglass into your living space. Our Documented Photo Record shows the liner condition before and after so you can verify it stayed intact. This is standard procedure on every Greenwood Village job with original fiberglass-lined trunks.
It does. At 5,600 feet, the low humidity cracks mastic seals and flex duct collars at Lennox plenum takeoffs faster than in lower-elevation suburbs like Aurora or Thornton. Thinner air at altitude also keeps wildfire ash particulate suspended longer, so post-smoke-event contamination penetrates deeper into the system. We inspect these junctions with a borescope during every Greenwood Village job and reseal with fresh mastic where needed - included in the written scope, not added later.
Probably not. In Greenwood Village, we regularly find that a partially blocked evaporator coil - hidden behind the cabinet panel on Signature Collection and Elite communicating systems - is causing the fault. The control board reads abnormal pressure or temperature and trips protectively. Cleaning the coil, not replacing the board or the furnace, usually resolves it. We remove the panel with OEM-compatible gaskets, clean the coil, and verify static pressure returns to Lennox spec. Bring us a competitor’s replacement quote and we will provide a Free Second Opinion in writing under the Haven Standard.
Because Lennox cabinet geometry, coil placement, and plenum transitions are specific enough that generic “all brands” training misses critical details. The clearance around a Signature Collection evaporator coil, the gasket pattern on an Elite series plenum panel, and the communicating control protocols on variable-speed systems all require brand-familiar technique. Our crews are trained on Lennox specifically, not just “HVAC generally.” That matters most in Greenwood Village’s large custom homes, where a mistake on a communicating system can cost days of diagnostic time.
