Lennox Air Duct Cleaning in Austin, TX | Bellows Air Duct & Vent Co. of Texas
Our Air Duct Cleaning in Austin for Lennox systems typically runs $350-$650 for a complete residential system, with most jobs finished in one visit. What sets our work apart is how we account for Austin’s Cedar Fever season and caliche dust loads that standard cleaning protocols miss. If you need your Lennox system inspected and cleaned right, call us at (866) 347-2063 for a free estimate with upfront pricing.
We are Bellows Air Duct & Vent Co. of Texas, an independent Lennox service provider - not manufacturer-authorized or factory-affiliated. Our technicians have worked on Lennox equipment across Austin for over a decade, from the Merit Series heat pumps in 78702 bungalows to the Signature variable-capacity systems in newer Hill Country builds. We know where these units fail in Central Texas conditions, and we stock the parts to fix them without waiting on factory shipping.
Wade Kellerman, our owner, grew up watching his grandfather repair heating systems out of a converted garage on Zang Boulevard in Oak Cliff. He learned the trade at Eastfield College in Mesquite and has spent the better part of three decades doing residential duct work. That background shows in how our Austin crews operate: camera inspection before and after every job, airflow numbers checked before we leave, and pricing disclosed before a single tool is lifted.
Why Austin Residents Choose Us for Lennox Service

Camera-verified results. And our 90-Day Done Right Promise - if it’s not right, we make it right, no paperwork, no arguing.
Our Austin technicians carry OEM-compatible Lennox parts and professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, and Aprilaire, plus specialized tools for Dryer Vent Cleaning - Austin homes need too.

Most jobs complete in a single visit by background-checked, uniformed techs who’ve seen what Austin’s climate does to ductwork.
We stand behind it - and around here, that has meant something for a long time.
Common Lennox Air Duct Cleaning Problems We Solve in Austin
- SLP98V modulating gas valve corrosion from humidity. Austin’s humidity swings - wet springs, then brutal dry summers - create condensation in venting runs that corrodes the SLP98V’s precision gas valve. We inspect the venting slope, clean accumulated moisture debris from the duct path, and verify valve operation before the next heating season.
- XC25 condenser coil fouling from caliche limestone dust. That white, powdery caliche from post-2010 construction sites gets pulled through return ducts and cakes onto the XC25’s outdoor coil. We’ve pulled filters in Mueller development homes that looked like they’d been dipped in chalk. Coil cleaning restores efficiency without the refrigerant charge games some shops play.
- ML14XC1 refrigerant leaks from thermal-cycled Schrader valves. Austin’s cooling season runs nine to ten months. That near-constant compressor cycling fatigues Schrader valve cores in the ML14XC1. During duct cleaning, we pressure-test the lineset and replace worn cores with OEM-spec parts before they become a full leak.
- Variable-speed blower motor bearing wear from cedar pollen buildup. Mountain Cedar pollen is ultra-fine and electrostatic - it clings to blower wheels in Signature and Elite series furnaces. The imbalance wears bearings and creates that low rumble homeowners describe as “a helicopter in the attic.” We remove the wheel, clean it properly, and check runout before reassembly.
- Post-construction drywall dust and debris in new-build ductwork. Austin’s 2010s-2020s boom means thousands of homes with Lennox systems that have never had their ducts cleaned after construction. We find drywall compound, insulation scraps, and caliche grit packed into trunk lines. Our video inspection shows you exactly what’s in there before we touch it.
Lennox Service in Austin: What Local Conditions Mean for Your Equipment
Austin sits in the Central Texas “cedar corridor,” where Ashe juniper releases pollen from December through February in concentrations that allergy researchers consistently rank among the nation’s worst. Locals call it Cedar Fever, and it creates a demand pattern for duct cleaning that doesn’t exist even ninety miles away in San Antonio. The pollen is uniquely fine - smaller than ragweed or oak - and penetrates standard return air filters. It accumulates in ductwork, on evaporator coils, and particularly on the variable-speed blower wheels of Lennox Elite and Signature series systems.
We serviced a 2021 Lennox ML14XC1 system at a bungalow on East 5th Street in 78702. The return ducts were choked with cedar debris from the last Cedar Fever season, causing the ML14 evaporator coil to ice over. Our tech cleaned the coil, sealed a leaky flex duct joint with mastic, and restored airflow to 1100 CFM. That job took four hours. The homeowner had been told by another company she needed a new compressor.
This seasonal reality shapes how we schedule Austin work. Late January through March is our busiest window - after the pollen peak, when residents who’ve suffered through Cedar Fever start connecting lingering symptoms to their duct systems. We stock extra evaporator coil cleaner and blower wheel assemblies through that period because demand is predictable. If you own a Lennox system in Austin, timing your duct cleaning for late February or early March, before the summer heat load hits, prevents the compounded load of pollen debris plus peak AC runtime.
Lennox Models & Products We Service in Austin
We work on the full Lennox residential lineup: Signature Series (SLP98V modulating furnace, XC25 variable-capacity heat pump), Dave Lennox Signature Collection (SL280V two-stage furnace), Elite Series (EL16XC1 single-stage heat pump), and Merit Series (ML14XC1, ML180UH). Our Austin warehouse stocks OEM Lennox parts where fit is critical - gas valves, control boards, pressure switches - and we source high-quality aftermarket equivalents from approved suppliers where they match OEM specs at lower cost.
Our standard Lennox sales & service protocol includes video inspection of the full duct run, evaporator coil cleaning with foaming cleaner safe for aluminum microchannel coils, and mastic sealant application at joint gaps. We don’t use duct tape. It fails in Austin’s attic heat.
For Austin’s older housing stock - the 1940s-1970s bungalows and ranch homes in 78702, 78703, 78704, and 78705 - we carry adapters for original uninsulated metal trunk lines and early-generation flex duct. Newer tract homes get attention to post-construction debris and caliche dust filtration. Either way, we show you the camera footage before we quote.

FAQs - Lennox Air Duct Cleaning in Austin
Yes. Mountain Cedar pollen is smaller and more penetrating than other regional pollens, and it accumulates in Lennox return systems from December through February. We’ve found cedar debris packed into blower wheels and coating evaporator coils by late January. If you’re still congested after the pollen peak ends, your ducts may be recirculating what collected. Call (866) 347-2063 for a free inspection - we’ll show you on camera.
Sometimes, but not always. If the SLP98V’s modulating gas valve has corroded from humid venting conditions - common in Austin - duct cleaning alone won’t restore heat. However, restricted airflow from debris-filled ducts can cause the furnace to lock out on high limit. We diagnose first, clean second, and replace only what’s actually failed. Our Free Second Opinion applies if you’ve already gotten a replacement quote.
We use OEM Lennox filters when they’re the right match for your system and MERR rating needs. We also stock high-quality aftermarket filters that meet or exceed OEM specs at lower cost. We never install a filter that doesn’t fit the rack properly - a gap around the edge defeats the point in Austin’s pollen environment.
Absolutely. Central Austin’s older housing stock is our regular work. Those uninsulated metal trunk lines from the 1940s-1970s often have gaps at joints and rust spots from decades of humidity cycling. We clean them with rotary brushes sized for metal duct, seal accessible joints with mastic, and flag any sections that need repair. The new Lennox blower will perform better with clean, sealed ducts behind it.
Lennox uses aluminum microchannel coils in many models - lighter and more efficient, but easier to damage with aggressive cleaning. Our techs use foaming cleaner and low-pressure rinse, not acid or high-pressure wands. In Austin, where coils ice over from restricted airflow (cedar debris, caliche dust), proper cleaning technique matters. We’ve serviced enough Lennox systems here to know the difference.
