Lennox Air Duct Cleaning in Greatwood, TX | Summit Air Duct Cleaning Service Texas
We provide independent Lennox air duct cleaning and HVAC cleaning service across Greatwood’s master-planned neighborhoods, from Brighton Lakes Drive to Riverbrooke Way. The one thing that makes our Lennox work here different: we’ve spent eight years learning how the Brazos River flood plain’s humidity and Hurricane Harvey’s lingering mold legacy specifically attack the flex-duct systems and evaporator coils in Greatwood’s 1988–2005 housing stock. Call (844) 886-2161 for a free video inspection and estimate.
Why Greatwood Residents Choose Us for Lennox Service
We’re not a general HVAC company that cleans ducts between installation jobs. We’re Summit Air Duct Cleaning Service — owner Michael Brown and our small crew — and Lennox systems in Greatwood are what we’ve built our reputation on over eight years and 775 verified reviews.
Michael grew up in Oak Cliff and cut his teeth on Texas HVAC systems through hands-on coursework at Eastfield College in Mesquite. He’ll crawl your attic himself, run the Rotobrush or Nikro rig, and show you phone-camera footage of what’s actually inside your ducts before recommending a thing. “I’ll show you what’s in there before I tell you what to do about it” — that’s how he’s worked since day one.
We carry Lennox OEM filters, coils, and motor parts for the G60, G71, and SLP98 furnace lines plus XC-series condensers and CBX air handlers commonly found in Greatwood homes. When OEM isn’t cost-effective, we source high-quality aftermarket duct boots and R-8 flex duct. No waiting on Dallas-area distributors to ship what we should already have.
Our 4.9-star average across 775 reviews didn’t happen by accident. It happened because the owner shows up and does the work.
Common Lennox Air Duct Cleaning Problems We Solve in Greatwood
- Premature evaporator coil fouling. The Brazos River valley pumps ambient humidity 15–20% higher than Sugar Land’s upland neighborhoods. Lennox XC20 and XC25 coils in Greatwood develop mold slime within two seasons, choking airflow and freezing the system. We pull and clean coils with foaming cleaner, then check drain pan slope — a detail others skip.
- Original flex-duct liner tears at support straps. Greatwood’s 1988–2005 flex duct runs have now endured 20–35 years of thermal cycling. The inner liner cracks at strap points, especially in attics that absorbed Harvey’s August 2017 flood vapor. Our video inspection catches tears standard cleaning misses; we seal with mastic or replace with R-8 flex when the damage is too far gone.
- CleanAir filter cabinet bypass from foundation settlement. Greatwood’s clay soils shift. Gaps open around Lennox filter cabinets, sucking attic insulation and dust straight past the filter and onto the blower wheel. We reseat cabinets and seal with foil tape — not duct tape, which degrades in attic heat.
- Return-air plenum mold from unremediated Harvey vapor. Homes that never saw interior flooding still had attic-mounted air handlers and return chases breathing humid, microbe-laden air for weeks in August 2017. We find silt and active mold colonies in Lennox plenums that post-storm inspections never touched.
- Blower wheel clogging from bypassed debris. Once insulation gets past a compromised filter cabinet, it wraps the CBX32M or CBX40U blower wheel like felt. We clean wheels in place when possible, pull and soak when necessary. Michael’s done enough of these to know which approach saves you money without cutting corners.
Lennox Service in Greatwood: What Local Conditions Mean for Your Equipment
Greatwood’s master-planned layout means homes on Brighton Lakes Drive and Riverbrooke Way share nearly identical flex-duct trunk-and-branch configurations — the same builder specs, the same attic pathways, the same failure timeline. That’s not generic. That’s local intelligence we use to your advantage.
We pre-map attic runs from street to street and stock pre-cut flex lengths before we arrive. A crew that treats every house as unique spends an hour figuring out what we already know. We spend that hour cleaning your Lennox system instead.
The humidity factor is real and measurable. Greatwood sits in the Brazos River bottom, where ground-level moisture pushes dew points higher than Fort Bend County communities even a few miles inland. Your Lennox system runs nine to ten months yearly, and without whole-home dehumidification, condensation forms inside flex ducts at support points and low spots. Mold colonizes there. Dust mites thrive. We’ve pulled flex duct sections from Riverbrooke Way attics where the inner liner was more biology project than airway.
Here’s what that looked like on one job: We cleaned a Lennox SLP98V system on Riverbrooke Way where the flex supply ducts had torn at the support straps due to 25 years of thermal cycling. Our video inspection showed mold colonies inside the torn sections from Harvey’s 2017 flood vapor. We sealed the tears with mastic and replaced two damaged runs with R-8 flex duct, restoring full airflow to the second-floor bedrooms.
Lennox Models & Products We Service in Greatwood
We maintain independent expertise — not factory-authorized, factory-dependent — across the Lennox model families most common in Greatwood’s 1988–2005 builds:
- G60 and G71 gas furnaces — mid-efficiency and two-stage units; we clean heat exchanger faces, inspect for cracks, replace inducer motors and pressure switches with OEM or matched aftermarket parts.
- SLP98V modulating gas furnace — premium variable-capacity unit; we service blower assemblies, clean condensate traps, and address the complex duct sealing these high-efficiency systems demand.
- XC20 and XC25 air conditioners — variable-speed condensers; coil cleaning and refrigerant line insulation checks are critical given Greatwood’s humidity load.
- CBX32M and CBX40U air handlers — attic-mounted workhorses; we clean blower wheels, replace OEM filters, and reseat filter cabinets compromised by foundation shift.
We stock Lennox OEM replacement filters, coils, and motor parts locally for same-day Greatwood turnaround. For duct repairs, we use high-quality aftermarket flex duct and boots when the job doesn’t demand factory components — saving you money without sacrificing performance.
Lennox Service Pricing in Greatwood
Our Lennox air duct cleaning and HVAC cleaning service in Greatwood typically runs $299–$549 for a complete duct system cleaning, depending on home size and duct count. Add $180–$340 for evaporator coil cleaning when needed. Flex duct repair or replacement runs $85–$220 per run, and video inspection is included with every estimate — no separate charge.
What drives cost: square footage, number of supply and return vents, accessibility of attic ductwork, and whether we’re cleaning, repairing, or replacing components. A 2,400-square-foot home on Brighton Lakes Drive with original 1995 flex duct and a dirty CBX32M blower takes longer than a newer build with cleaner access.
Every estimate starts with our video inspection. You’ll see what we see. Call (844) 886-2161 to schedule — estimates are free, and we often have same-day openings for Greatwood calls.

FAQs — Lennox Air Duct Cleaning in Greatwood
No. We’re an independent service provider with NADCA-certified technicians and Lennox-specific training on G60, G71, SLP98, XC, and CBX model lines. We source OEM and quality aftermarket parts, but we don’t represent Lennox or its dealer network. This keeps our pricing straightforward and our recommendations unbiased. Call (844) 886-2161 with questions about your specific unit.
We use low-RPM Rotobrush contact cleaning with soft poly bristle whips, not high-pressure air whips that tear aged liner. Our video inspection first identifies weak points — support strap tears, sagging low spots, Harvey-era moisture damage — and we mark those sections for hand cleaning or repair rather than aggressive agitation. For ducts past saving, we quote R-8 flex replacement before touching anything. Call (844) 886-2161 for a video inspection — we’ll show you exactly what condition your 1992 ducts are in.
Very possibly. The Brazos River’s record crest in August 2017 pushed flood vapor — not liquid water, but saturated, microbe-laden air — into attics and crawl spaces across Greatwood for days. Attic-mounted Lennox air handlers and return-air plenums breathed that air continuously. We’ve found silt deposits and active mold in plenums from homes that never took interior water. Our video inspection checks these cavities specifically. Call (844) 886-2161 if your system was running during Harvey and hasn’t been thoroughly inspected since.
Because coil cleaning alone doesn’t fix the root cause in Greatwood’s humidity. Lennox XC-series coils here foul quickly due to the Brazos flood plain’s ambient moisture load. We clean the coil, yes — but we also verify drain pan pitch, check blower wheel condition, inspect flex duct for tears that reduce return airflow, and evaluate whether your system needs better dehumidification. Restricted airflow from damaged Greatwood flex duct is the hidden culprit behind half the freeze-ups we diagnose. Call (844) 886-2161 and we’ll trace the full pathway.
Usually, yes. The CBX32M’s blower compartment opens from the side, and with the right access panel clearance — which we verify first — we can extract, clean, and rebalance the wheel in place. Tight attic spaces or severe buildup may require partial disassembly, but we avoid full unit pulls when possible. Michael Brown assesses access during our initial video inspection and tells you upfront which approach applies. Call (844) 886-2161 to schedule.
Yes. We run borescope cameras through the full return pathway — floor grille, chase cavity, attic plenum connection — not just the visible duct runs. In Greatwood, we’ve found mold in chase cavities that standard duct cleaning completely misses, especially in post-Harvey homes where vapor entered from attic penetrations. The inspection is included with every estimate. Call (844) 886-2161 to book.
