Why Georgetown Residents Choose Us for Lennox Service
We’ve cleaned Lennox ductwork in Georgetown since 2012 — over 4,500 jobs on units ranging from 1990s Merit Series gas furnaces to new Signature variable-capacity systems. Michael Brown, our owner, still leads every job personally. He grew up in Dallas’s Oak Cliff neighborhood, trained hands-on at Eastfield College in Mesquite, and spent years refining his technique before launching Summit eight years ago. That background matters when he’s crawling through a Sun City attic at 2 PM in July, reading the sag pattern on a 2001 Lennox flex run.
We don’t send crews. We don’t subcontract. The owner shows up and does the work, equipped with Rotobrush and Nikro systems — the same tools commercial restoration contractors use, not shop vacs with brush attachments. Our 4.9-star average across 775 verified reviews reflects what happens when one person owns the outcome from phone call to final walkthrough.
For Lennox owners specifically, we maintain detailed records of duct layouts, failure patterns, and filter configurations across Georgetown’s distinct housing zones. We stock OEM Lennox filter media and replacement flex duct through Johnstone Supply, so we’re not waiting on shipping while your system runs dirty. Eight years focused on one trade means we’ve seen how Lennox designs age in Texas attics — and we know the difference between a cleaning job and a repair job that cleaning alone won’t fix.
Common Lennox Air Duct Cleaning Problems We Solve in Georgetown
- Collapsed flex duct at unsupported mid-spans. In Sun City’s 1995–2012 builds, original Lennox flex duct was run across 20- to 25-foot joist spans with inadequate support straps. Decades of 140°F Georgetown attic heat soften the inner liner until it collapses, trapping cedar pollen, insulation fibers, and dust into a dense mat that chokes airflow. Standard filter changes never reach this. Our video inspection catches it before we quote.
- Warpered CleanAir filter cabinets on Merit Series units. The 1990s–2000s Lennox Merit systems common in early Sun City phases used plastic media frames that warp under thermal cycling. Once the seal gaps, attic insulation pulls straight through and coats the evaporator coil. We replace with OEM Lennox cabinets or retrofit properly sealed aftermarket frames — never tape-and-pray fixes.
- Return plenum baffle cracks on Signature two-stage systems. The internal baffle in Lennox Signature Series return plenums can crack from years of heating and cooling cycles, creating a hidden debris reservoir. Without video inspection, this reads as “dirty ducts” when it’s actually a structural failure collecting particulate. We’ve found this on multiple SLP98V units in Georgetown Village and Teravista.
- Construction debris in new Wolf Ranch and Teravista builds. Post-2015 Lennox systems in Georgetown’s new-construction zones often have duct boots that were left uncapped during drywall sanding. The supply plenum pulls fine drywall dust from day one, coating coils and blower wheels before the homeowner’s first filter change. We clean the full pathway — plenum to register — and seal boots with OEM Lennox collars and mastic.
- Cedar pollen loading in return systems. Georgetown sits on the Balcones Escarpment at the eastern edge of the Ashe juniper belt. December through February, ultra-fine cedar pollen coats return-air grilles and duct interiors. Lennox systems with standard 1-inch filters can’t capture it. We find pollen mats 2–3 inches thick in duct trunks during late-winter cleanings — a burden Round Rock and Taylor systems simply don’t face.
Lennox Service in Georgetown: What Local Conditions Mean for Your Equipment
Georgetown’s Sun City Texas development — over 7,000 homes built between 1995 and 2012, almost entirely with attic-run Lennox flex duct — creates a market reality no neighboring city replicates. These systems are now 15 to 28 years old, serving a demographic that’s immunologically vulnerable and particularly sensitive to indoor air quality. The long horizontal duct runs, often 40 feet or more across slab-on-grade single stories, sag at strap points after decades of thermal cycling. We’ve video-inspected homes on Catamaran Drive where collapsed inner liners had been pulling 140°F attic air into living spaces for multiple cooling seasons, the homeowner unaware because the register still blew — just weakly and hot.
This isn’t a maintenance lapse. It’s a Georgetown-specific failure pattern driven by housing stock age, attic geometry, and Texas heat intensity that contractors from Cedar Park or Pflugerville don’t encounter at this density. When we quote a Lennox duct cleaning in 78633, we’re already planning for the probability of structural repair — not because we’re upselling, but because we’ve seen what 4,500 Georgetown jobs have taught us. Clean ducts to sealed ducts to healthier air: that’s the full pathway we cover, no second contractor needed.
Lennox Models & Products We Service in Georgetown
We service the full Lennox residential lineup, with particular depth on the units most common in Georgetown’s housing stock:
- Signature Series: SLP98V modulating gas furnace, XC25 variable-speed heat pump — two-stage and variable-capacity duct layouts with complex return plenums
- Dave Lennox Signature Collection: EL296E high-efficiency furnace, CBX32MV variable-speed air handler — early 2000s installs concentrated in Sun City’s Phase 1–3
- Elite Series: EL16XC1 single-stage AC, EL195UH090XE gas furnace — mid-range systems in Teravista and Georgetown Village transitions
- Merit Series: ML14XC1, ML195UH090E — the workhorse line in 1990s–2000s Sun City builds, often paired with CleanAir filter cabinets
We source OEM Lennox filter media, boot collars, and flex duct through Johnstone Supply, with R-8 insulation rated for Georgetown attic conditions. For repairs, we specify Lennox OEM mastic tape and collars over aftermarket alternatives — the thermal expansion rates match, and the seals hold through Texas summer. When flex duct is aged beyond repair, we say so transparently. No cleaning-only upsells on ductwork that needs replacement.
Lennox Service Pricing in Georgetown
Lennox air duct cleaning in Georgetown ranges from $280 for a compact single-system Sun City home to $520 for larger multi-zone Signature Series setups with video inspection and evaporator coil cleaning included. Flex duct repair adds $180–$340 per section depending on accessibility and R-value requirements. CleanAir cabinet filter replacement runs $85–$140 with OEM media.
What drives cost: system age (older Merit units need more disassembly), attic accessibility (steep-pitch trusses versus walkable scuttle), and whether video inspection reveals structural failures requiring repair before cleaning is worthwhile. Our free estimate includes full video documentation, airflow testing at key registers, and a written scope — no charge, no obligation. Call (844) 886-2161 for exact pricing on your Lennox system.

FAQs — Lennox Air Duct Cleaning in Georgetown
No. Summit Air Duct Cleaning Service Texas is an independent service provider with no manufacturer affiliation. We’ve serviced Lennox systems in Georgetown since 2012 and maintain detailed records of their duct layouts and failure patterns, but we don’t perform warranty repairs or installation. For warranty issues, contact your installing Lennox dealer directly. For duct cleaning, repair, and air quality work, call (844) 886-2161.
Sun City Texas HOA guidelines focus on exterior maintenance and contractor insurance verification, not duct cleaning methods specifically. We carry general liability and workers’ compensation documentation that satisfies their vendor requirements, and we protect flooring and furnishings during indoor work. The only “special” consideration is the age of your Lennox flex duct — most Sun City systems need video inspection before cleaning to rule out collapsed sections. Call (844) 886-2161 to schedule; we’ll handle HOA documentation if needed.
It’s likely neither the filter nor the unit alone. In Georgetown’s cedar pollen zone, standard 1-inch Merit filters load rapidly December through February. But if filters soil unusually fast year-round, check for a warped CleanAir cabinet frame or a return plenum leak pulling attic debris — both common on 2008 Merit installs in Sun City. Our video inspection identifies the source; cleaning without fixing the bypass just wastes money. Call (844) 886-2161 for a diagnostic estimate — free, with footage you can see.
Sometimes. Musty odors in new-construction Wolf Ranch homes often stem from drywall dust and moisture trapped in the supply plenum since build-out — duct cleaning removes this. But if the evaporator coil has microbial growth or the condensate pan drains poorly, coil cleaning and pan treatment are needed too. We inspect both before quoting. For a precise diagnosis on your Lennox system, call (844) 886-2161.
Yes. We stock and install OEM Lennox CleanAir media in the correct MERV ratings for your system. We don’t substitute aftermarket filters that don’t seat properly in Merit and Elite Series cabinets — improper fit gaps the seal and lets debris bypass. Replacement typically runs $85–$140 depending on cabinet size and media type.
Start with video inspection. Restricted airflow codes on newer Signature systems often trace to duct boots left uncapped during construction, now partially blocked with drywall debris — common in Teravista’s 2018–2022 build phases. But we’ve also found crushed flex duct from trades stepping on runs during finish work. Cleaning helps if the restriction is debris; repair is needed if the duct is structurally damaged. We determine which before quoting. Call (844) 886-2161 for same-day diagnosis.
