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.
Lennox Air Duct Cleaning in Cibolo, TX | CleanRun Air Duct Cleaning Schertz
Independent Air Duct Cleaning - Cibolo for Lennox systems runs $280-$520 for a complete duct system cleaning, depending on home size and whether the evaporator coil needs attention. We’re not a Lennox dealer or authorized servicer - we’re an independent company that works on Dave Lennox Signature, Elite, and Merit systems in Cibolo every week, and we document every duct run with before-and-after photos. If your Lennox system was installed in a post-2000 tract home here, there’s a strong chance the ductwork still holds construction debris from the day you moved in. Call (830) 402-5110 for a written estimate before any work starts.
Why Cibolo Residents Choose Us for Lennox Service
Tomas Reyes, our owner, grew up in Queens and learned the trade at Apex Technical School in Long Island City. He’s spent the better part of two decades pulling flex duct, cleaning plenums, and documenting what actually lives inside residential HVAC systems. The crew has been working the Schertz area for several years now - everything from newer builds off Roy Richard Drive to older homes where the ductwork hasn’t been touched since installation. Cibolo service area coverage means we’re routinely on roads like the Purple Heart Trail and 90th Infantry Division Highway, often multiple times per week.
We know Lennox equipment because we encounter it constantly in Cibolo’s housing stock. The Dave Lennox Signature Collection variable-speed furnaces, the Elite Series two-stage units, and the Merit Series single-stage workhorses - we’ve cleaned ducts and coils on all of them. We carry OEM-equivalent aftermarket parts that meet Lennox specs for common repairs (blower motors, flex duct, mastic sealants) and source OEM Lennox components when proprietary control boards or blower assemblies are required. Every job starts with a written price under Haven Standard Clause 1. No exceptions. The before photo does the talking. We just bring the camera.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is backed in writing on every job. And every customer receives a Documented Photo Record of every duct run, included as standard since our first job in 2013.
Common Lennox Air Duct Cleaning Problems We Solve in Cibolo

- Construction debris in post-2000 flex duct. Cibolo’s explosive growth from 3,000 to 30,000+ residents meant builder-grade Lennox systems were installed fast, with unsealed flex-duct joints that were never cleaned before first use. We regularly pull out drywall dust, caliche limestone particulate, and spray-foam particles that have been circulating since move-in day.
- Collapsed flex runs in caliche-heavy environments. The fine caliche dust along corridors like Roy Richard Drive gets drawn into HVAC intakes, accumulating in return trunks and adding weight to flexible ducting. Lennox Merit and Elite series horizontal attic returns are particularly vulnerable - the dust load can partially collapse a flex run, choking airflow and causing the PSC or variable-speed blower to overwork.
- High static pressure from dirty coils during 100°F summers. Cibolo’s cooling season runs nearly continuously from May through September. Any particulate load in Lennox ducts circulates constantly, coating the evaporator coil and raising static pressure. Variable-speed air handlers throw low-airflow faults and shortened cooling cycles as a result.
- Cedar pollen film on coils and duct interiors. From late November through February, Cibolo sits in one of the heaviest mountain cedar pollen zones in North America. The sticky pollen penetrates return vents and coats Lennox evaporator coils and duct walls, creating an adhesive layer that traps additional dust for months after the season ends.
- Attic insulation fibers through pinhole leaks. Post-2000 flex duct in Cibolo’s newer builds develops pinholes over time, particularly where it contacts framing or where caliche dust has abraded the outer jacket. The negative pressure in Lennox return systems pulls attic insulation fibers directly into the airstream - visible as a gray, fibrous buildup at the plenum connection.

AfterLennox Service in Cibolo: What Local Conditions Mean for Your Equipment
Here’s the specific dynamic that shapes our Lennox work in Cibolo, and it wouldn’t be equally true even fifteen minutes away in San Antonio. Because so many Cibolo homes were built between 2000 and 2020 during the city’s explosive growth, their Lennox systems were often installed with unsealed flex-duct joints that were never cleaned after construction - meaning the first duct cleaning in these homes typically removes drywall dust and caliche particulate that has literally been in the system since day one. We’ve opened return plenums in Comal Community subdivisions and found a quarter-inch layer of beige-gray caliche settled at the low point, undisturbed for fifteen years because no prior technician had run a camera through - a problem our Cibolo Dryer Vent Cleaning customers often report in their laundry ducts too. The Lennox blower wheel on these systems is often coated with the same material, reducing efficiency in a climate where the air conditioner already runs hard enough. When we clean a Lennox system in Cibolo, we’re not performing routine maintenance on a used system - we’re often completing the construction cleanup that should have happened before the homeowner ever turned the key.

FAQs - Lennox Air Duct Cleaning in Cibolo
The filter only catches what reaches it. In Cibolo’s post-2000 builder-grade homes, unsealed flex-duct joints and construction debris in the return trunk bypass the filter entirely, circulating drywall dust and caliche particulate through your living space. We see this on Lennox Elite and Merit systems weekly - the filter looks clean while the duct interior does not. Call (830) 402-5110 for a video inspection and written estimate.
Yes. We use low-pressure rotary brushing and controlled negative-pressure extraction, not aggressive mechanical agitation that can tear thin flex duct. Our techs inspect each run with a borescope before selecting the tool - if a section is too degraded to clean safely, we’ll show you the photo and quote repair before proceeding. The 365-Day Done Right Promise covers our workmanship.
We start with a video inspection of the return trunk, supply plenum, and at least two branch runs. Many military families near Randolph AFB inherit systems with zero maintenance history - we treat every unknown system as potentially holding construction debris until the camera proves otherwise. The inspection itself is part of our free estimate process.
Significantly. From late November through February, mountain cedar pollen penetrates return vents and coats Lennox evaporator coils and duct interiors with a sticky, adhesive film. The pollen layer then traps additional dust through spring and summer, compounding airflow restrictions. Cleaning after cedar season ends - typically March - removes the accumulated film before the heavy cooling load begins. Call (830) 402-5110 to schedule post-season service.
Individual flex-duct runs and plenum joints are repairable in most cases. We replace damaged flex sections with new insulated duct, mastic-seal all connections to the plenum, and pressure-test the repair. Full duct replacement is only necessary when multiple runs are degraded or the main trunk itself is compromised - we’ll show you the camera evidence and give an honest repair-vs-replace assessment with both options priced in writing.
