Lennox Air Duct Cleaning in Colleyville, TX | Summit Air Duct Cleaning Service Texas
Independent Lennox air duct cleaning in Colleyville, TX typically runs $280–$550 for a full system cleaning depending on square footage and duct condition, with most jobs completed in a single visit. What sets our work apart is the intersection of real Lennox system knowledge with Colleyville’s unique contamination profile—jet exhaust particulates from DFW International Airport, 20–40 year old flex duct in oversized HVAC systems, and Cross Timbers pollen loads that generic cleaners simply don’t account for. Call (844) 886-2161 for a free estimate and video inspection.
Why Colleyville Residents Choose Us for Lennox Service
We’ve cleaned more than 1,200 Lennox systems in Colleyville over eight years, and we’ve learned what the manufacturer’s manual won’t tell you: how that Elite Series air handler performs after two decades of North Texas attic heat, or where the G20 furnace’s downflow plenum traps debris that standard equipment can’t touch.
Michael Brown grew up in Oak Cliff and built Summit Air Duct Cleaning Service after hands-on coursework at Eastfield College in Mesquite and years refining technique in Texas homes. He still leads every job personally. “I’ll show you what’s in there before I tell you what to do about it”—that’s how we work. Customers see their own ductwork on our video inspection before we recommend a thing.
Our equipment fleet includes Rotobrush and Nikro systems, the same tools commercial restoration contractors use, plus Abatement Technologies HEPA vacuums. No shop vacs. No subcontracted crews. When you book Summit, you get Michael Brown on-site with equipment built for this job.

Common Lennox Air Duct Cleaning Problems We Solve in Colleyville
- Sagging flex duct with jet-exhaust residue. Lennox thin-wall flexible ductwork from 1990s installations pools debris in low spots, especially in Colleyville’s oversized systems with low airflow velocity. DFW Airport’s eastern departure corridor deposits ultrafine particulates that bond with Texas dust into a dense, oily mat. Our video inspection spots the sag; our Rotobrush system breaks it loose.
- Fiberglass duct board delamination. Lennox plenum connections in Colleyville attics face summer temperatures exceeding 140°F. The fiberglass duct board separates at seams, releasing glass fibers into your airstream. We replace degraded boots with sealed collars—OEM when available, high-grade aftermarket with equivalent R-value when not.
- ‘CleanAir’ filter cabinet corrosion. Those 1990s Lennox filter frames corrode as rubber seals degrade, pulling unfiltered attic air straight through gaps. We stock replacement cabinet frames and seals for proper restoration.
- G20 furnace ‘well’ plenum compaction. The downflow design of Lennox G20 and G26 series creates a sediment well beneath the heat exchanger. Decades of accumulation form a dense mat that consumer-grade vacuums can’t extract. Our Nikro system with whipping attachments breaks it free.
- Evaporator coil fouling from Cross Timbers pollen. Live oak and cedar elm seasons in Colleyville coat Lennox coil fins with biological debris that restricts heat transfer. Coil cleaning is standard on our full-system jobs, not an upsell.
Lennox Service in Colleyville: What Local Conditions Mean for Your Equipment
Colleyville’s position immediately east of DFW International Airport means its homes, especially those between Glade Road and John McCain Road under the eastern departure route, accumulate jet-exhaust particulates in return-air systems at levels two to three times higher than neighboring cities like Keller or Southlake. Our video inspections consistently reveal dark, oily residue on Lennox coil fins and black staining on flex duct interior walls that we simply don’t see in communities farther from the runways.
This isn’t theoretical. On a recent job in the Shady Valley Country Club Estates off Glade Road, our crew inspected a 2002 Lennox Elite Series system where the homeowner reported reduced airflow. Our video inspection revealed sagging flex duct runs in the attic coated with black jet-fuel residue from years of DFW exposure, and a delaminated fiberglass plenum boot at the air handler. We stabilized the flex, replaced the degraded boot with a new sealed collar, and performed a full HEPA vacuuming of the trunk lines, restoring static pressure within factory specs.
The large custom homes built throughout Colleyville’s 76034 ZIP—most 3,500 to 6,000 square feet, constructed 1985 to 2005—compound this problem. Oversized HVAC systems were spec’d for prestige square footage, not proper airflow engineering. Low velocity through long horizontal flex runs lets particulates settle instead of staying suspended. Your Lennox system works harder, your filters clog faster, and your indoor air carries a contamination signature unique to this corridor.
Lennox Models & Products We Service in Colleyville
We handle the full range of residential Lennox equipment found in Colleyville’s housing stock: G20 and G26 gas furnace series, Elite Series air conditioners, CS7 and CS8 air handler lines, and XC/YX split-system heat pumps. Eight years focused on one trade means we’ve seen the evolution of Lennox flex-duct specifications, filter cabinet designs, and coil configurations across production years.
For critical components—filter frames, plenum seals, cabinet hardware—we prioritize OEM Lennox parts to ensure proper fit and longevity. When OEM flex duct is unavailable or discontinued, we use high-grade aftermarket material with equivalent R-value, and we’re transparent about the choice. We never recommend full duct replacement when cleaning and targeted repair will restore performance. Our Colleyville inventory includes common Lennox seals and cabinet components for same-day completion.

FAQs — Lennox Air Duct Cleaning in Colleyville
Every two to three years for most Colleyville homes, versus the three-to-five-year standard for inland North Texas cities. The DFW Airport jet-exhaust particulates accelerate buildup in return-air systems, and our video inspections show visibly heavier residue here than in Keller or Southlake. Homes between Glade Road and John McCain Road typically need the shorter interval. Call (844) 886-2161 and we’ll assess your specific system.
Yes—often measurably. The downflow well beneath the G20 heat exchanger compacts sediment into a dense mat that restricts airflow and forces the blower motor to work harder. Our Nikro system with mechanical whipping attachments removes material that standard vacuums leave behind. We’ve restored static pressure to factory specs on dozens of Colleyville G20 units.
We replace them when corroded or when seals have degraded enough to allow unfiltered attic air infiltration—common in 1990s Lennox installations. We stock OEM-compatible filter cabinet frames and hardware for same-day completion in Colleyville. If your cabinet is sound, we clean and reseal it instead.
Most sagging can be repaired. We stabilize flex duct with proper support straps, eliminate low spots where debris pools, and seal connections. Replacement is only necessary when the duct material itself has torn, delaminated, or degraded beyond structural integrity. Our video inspection shows you the difference before you decide. Call (844) 886-2161 for a free assessment.
The combination of DFW jet-exhaust particulates and heavy Cross Timbers pollen creates a sticky, layered fouling on coil fins that dry-brush methods won’t remove. Colleyville’s near-continuous AC operation May through September bakes this residue onto the coils. We use foaming cleaners and low-pressure rinsing specific to Lennox coil fin spacing, followed by verification with our video borescope.
