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.

Why Schertz Residents Choose Us for Lennox Service
We’ve been pulling flex duct and cleaning plenums in Schertz for several years now. The runs off Roy Richard Drive, the subdivisions along FM 78, the newer builds near Seguin Road - we’ve worked them all. Tomas Reyes, our owner and lead technician, started this trade at Apex Technical School in Long Island City and spent the better part of two decades documenting what actually lives inside residential HVAC systems before bringing that practice to Schertz in 2013.
Our Lennox sales & service covers Merit, Elite, and Dave Lennox Signature Collection equipment. We stock OEM-compatible blower motors, control boards, and coil cleaners for fast turnaround, and we carry aftermarket flex duct and mastic sealant from Guardsman and Abatement Technologies for repairs that don’t require factory parts. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The before photo does the talking. We just bring the camera.
Common Lennox Air Duct Cleaning Problems We Solve in Schertz
- Delaminated flex duct liner shedding fiberglass. Schertz attics routinely exceed 150°F in July and August. After two decades of that heat, the inner liner on builder-grade flex duct - common in Lennox systems installed during the 2000s building boom - separates from the wire helix and releases fiberglass particulate directly into your airstream. We photograph the damage, repair or replace the affected runs, and document the fix.
- Undersized return ducts pulling attic dust. Subdivisions along the FM 78 and Seguin Road corridors frequently used regional HVAC subcontractors who ran returns too small for the system tonnage. The restricted opening increases static pressure, which pulls attic dust past loose seams at higher velocity. Your Lennox air handler works harder, your filters load faster, and your ducts contaminate sooner than the home’s age would suggest.
- Evaporator coil fouling from Ashe juniper pollen. Schertz sits on the eastern edge of the Hill Country transition zone, which means December through February brings some of the most intense Mountain Cedar pollen events in the country. Fine particulate bypasses standard 1-inch filters and coats the Lennox evaporator coil, reducing heat transfer and raising head pressure. Coil cleaning is standard on our full system service.
- Blower wheel imbalance from particulate buildup. Lint, pollen, and construction debris accumulate on the blower wheel of Lennox air handlers over years of deferred maintenance. The resulting imbalance strains the motor, reduces delivered airflow, and can trip high-limit safeties. We remove and clean the wheel as part of every full system cleaning - not a separate upsell.
- Deferred maintenance in military rental properties. Schertz’s adjacency to Joint Base San Antonio-Randolph means an unusually high share of housing cycles through PCS orders every 2-3 years. Tenant occupants don’t invest in HVAC upkeep; landlords address visible failures between tenants. We regularly find 5-10 years of buildup in Lennox systems that should have been cleaned every 3-5 years.
BeforeAfterLennox Service in Schertz: What Local Conditions Mean for Your Equipment
Here’s the Schertz factor that shapes our Lennox work more than any other: the military rental churn. Homes near the base - and that’s a significant slice of Schertz’s housing stock - turn over fast. A family arrives on orders, lives in the house for a two or three-year tour, and leaves. The next family does the same. Nobody calls for Air Duct Cleaning - Schertz because nobody plans to stay long enough to care. The landlord swaps the carpet, patches the walls, and rents it again. The Lennox system in the attic keeps running, and the ducts keep accumulating.
We’ve cleaned Merit Series air handlers in these properties where the return plenum held three inches of compacted dust and pet dander - not from neglect by any one occupant, but from systemic deferral across multiple tenants. The flex duct liner had started to delaminate from years of attic heat with no inspection. This pattern is concentrated in Schertz in a way you simply don’t see at the same density in Converse or Universal City. It’s not a moral failing; it’s a structural condition of the local housing market, and it means Lennox owners in Schertz need to verify their duct status independently rather than assume prior tenants handled it.
Lennox Models & Products We Service in Schertz
We regularly service three Lennox product tiers. The Merit Series - units like the ML14XC1 heat pump and ML180 gas furnace - represents the bulk of Schertz’s installed base from the 2005-2015 construction period. These systems use standard PSC blower motors and fixed-orifice metering devices; straightforward to clean, but the flex duct connections are where we find the most deferred damage.
The Elite Series, including the EL16XC1 and EL296V, adds variable-speed blower technology and more sophisticated control boards. These components require careful handling during duct cleaning - we use OEM Lennox parts when control boards need replacement, and we document coil condition with the photo record because variable-speed systems are more sensitive to airflow restriction.
The Dave Lennox Signature Collection - the SL28XCV and SLP98V - represents the premium tier with modulating gas valves and communicating thermostats. We service these systems with the same documentation protocol, and we stock compatible OEM components for repairs that arise during cleaning. For consumable materials like flex duct and sealant, we use aftermarket equivalents from Honeywell and Aprilaire that meet or exceed Lennox specifications.

FAQs - Lennox Air Duct Cleaning in Schertz
Every 3-5 years for owner-occupied homes; every 2-3 years for rental properties near Joint Base San Antonio-Randolph due to higher turnover and deferred maintenance. Consider our Dryer Vent Cleaning in Schertz on the same schedule. If your flex duct was installed during the 2000s building boom, add an inspection for liner delamination - the 150°F+ attic temperatures in Schertz accelerate that failure mode. Call (830) 402-5110 to schedule an inspection with photo documentation.
Yes. The December-February Mountain Cedar events in Schertz produce fine particulate that passes through standard 1-inch filters and adheres to the evaporator coil. A coated coil reduces heat transfer efficiency and can cause the system to run longer cycles. We inspect and clean the coil as part of our full system service, and we document the condition with before-and-after photos.
Partial delamination can often be repaired with liner reinforcement and proper mastic sealing; complete separation or widespread brittle cracking requires run replacement. We make this assessment with the borescope camera, show you the footage, and quote both options in writing before proceeding. No work starts without your written approval of the price.
Attic location is standard in Schertz and does not add to our base pricing. We bring portable staging and lighting rated for unconditioned space work. The documented photo record is especially valuable for attic systems because you can’t easily inspect the work yourself - we deliver the images as part of your standard job record.
Yes. We seal accessible duct seams with mastic from Guardsman and Abatement Technologies, and we test for leakage with a smoke pencil. For homes with the undersized returns common along FM 78, sealing is often more critical than cleaning alone - restricted airflow pulls unfiltered attic air through every gap. The sealing scope and price are written before work begins. Call (830) 402-5110 for an assessment.
