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.

AfterLennox Air Duct Cleaning in San Antonio, TX | CleanRun Air Duct Cleaning San Antonio
CleanRun provides independent Lennox service across San Antonio, not manufacturer-authorized work. The difference that matters here: our crews have cleaned thousands of Lennox systems in this market specifically, and we know how Ashe juniper pollen from the Edwards Plateau coats duct interiors from December through February while most other markets are slow. For a full overview of our Air Duct Cleaning - San Antonio services, call for details. Call (726) 600-7155 for a written estimate before any work starts.
Why San Antonio Residents Choose Us for Lennox Service
We’ve worked on Lennox equipment in San Antonio since 2013, from the 1970s-90s tract subdivisions in Stone Oak and the Helotes corridor to the pre-WWII craftsman bungalows in Monte Vista and Lavaca. Our technicians carry OEM-equivalent Lennox flex duct, mastic, and coil cleaning chemicals on every truck, and we source genuine Lennox control boards and motors when the repair calls for them. We’re not authorized by Lennox. We’re an independent shop, which means no brand loyalty is steering our recommendation when a straight repair-vs-replace read is what you actually need.
Tomas Reyes, who leads our crew, trained in HVAC systems technology at Queensborough Community College and spent years doing hands-on ductwork across the Northeast before shifting focus to San Antonio. He and his team have logged thousands of cleaning hours here. The camera goes in first. Then we talk. Every job starts with a written price delivered before a single panel comes off, and every duct run is photographed before and after as part of our standard deliverable. That’s Haven Standard Clause 1, and it’s been non-negotiable since our first San Antonio job.
Common Lennox Air Duct Cleaning Problems We Solve in San Antonio
- Flex-duct seam separation in 150°F attics. Lennox air handlers installed in unconditioned attic space on north-side San Antonio homes - Stone Oak, Cibolo, Converse - cook attached flex duct until the inner liner cracks and insulation sags. We find separated seams pulling attic air straight into the supply stream, sometimes dropping delivered airflow by 30% or more before a homeowner notices anything wrong.
- Evaporator coil fouling from caliche and limestone dust. Southwesterly dust events off the western plains deposit fine particulate into Lennox Merit and Elite series systems, especially where return plenums are undersized or poorly sealed. The coil fins clog, pressure drop rises, and the compressor starts working harder for less cooling.
- Blower motor and wheel contamination from cedar pollen. During San Antonio’s Cedar Fever season, Lennox return-air grilles pull enormous volumes of Ashe juniper pollen into the system. It sticks to blower wheels, throws off balance, and can trigger nuisance high-limit trips when airflow drops below spec.
- Failed mastic and brittle foil tape at plenum takeoffs. On 1990s-2000s Lennox installs, thermal cycling in San Antonio’s unconditioned attics turns mastic hard and foil tape brittle. Gaps open at the plenum-duct connection, and the system starts leaking conditioned air into the attic while pulling dust and insulation fibers back in.
- Collapsed flex duct on long attic runs. Lennox systems in two-story San Antonio tract homes often have 20-foot-plus flex duct runs across hot attics. Over time the wire helix fatigues, the duct kinks or collapses entirely, and rooms at the far end of the house stop getting airflow while the system runs longer cycles trying to compensate.
BeforeAfterLennox Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio sits at the southern edge of the Edwards Plateau, and that geography creates a duct cleaning demand pattern you won’t find in Houston, Dallas, or Austin. Ashe juniper - what locals call mountain cedar - releases pollen from December through February that produces some of the highest pollen counts recorded anywhere in the United States. While most markets see their slow season in winter, San Antonio Lennox systems are pulling that pollen through return-air grilles on every heating cycle, coating duct interiors and recirculating allergens with each fan start.
Last January we pulled the return drops on a 2005 Lennox Merit system in a Stone Oak two-story and found the flex duct interior coated in a thick, greenish-yellow film of cedar pollen. The homeowner had been waking up congested every morning. After full system cleaning and sealing several separated flex seams in the attic, their blower amp draw dropped and they stopped calling us about “the house smelling like the outside.” We also offer our Dryer Vent Cleaning in San Antonio for comprehensive home air quality. That’s a San Antonio problem, not a generic duct problem, and it’s why we schedule more Lennox cleanings here in January than we do in April.
Lennox Models & Products We Service in San Antonio
We clean and service the full current and recent-production Lennox lineup, including Merit Series units like the 14ACX and ML14XC1, Elite Series systems including the EL16XC1 and XC21, and the Dave Lennox Signature Collection models such as the XC25 and SL28XP. We also work on iComfort and iHarmony zoning systems, where dirty ductwork throws off the balanced airflow these controls are trying to manage.
Our trucks stock OEM-equivalent Lennox flex duct, mastic, foil tape, and coil cleaning chemicals for same-day repairs. When a control board, blower motor, or other proprietary component has failed, we source genuine Lennox parts rather than universal substitutes that don’t match the OEM spec. Because we’re independent, we can also tell you when a repair doesn’t make financial sense on an aging Merit or Elite unit, something an authorized dealer with sales quotas sometimes won’t.
Lennox sales & service across all model lines is our focus, not a sideline.
Lennox Service Pricing in San Antonio
Whole-system Lennox air duct cleaning in San Antonio typically runs $450-$850 for a single residential system, depending on total duct run length, accessibility of the attic or crawl space, and whether evaporator coil cleaning and duct sealing are included. A standalone coil cleaning on an accessible Lennox Elite or Signature unit generally falls in the $280-$420 range. Duct sealing with mastic and proper mechanical fastening adds $200-$400 depending on how many takeoffs and joints need attention.
Every estimate starts with a camera scope of the duct interior, and we deliver a written price before any work begins. No per-vent pricing. No coupon that triples once the truck is in your driveway. The price we write is the price you pay.

FAQs - Lennox Air Duct Cleaning in San Antonio
Ashe juniper pollen from the Edwards Plateau peaks December through February, and your Lennox return-air grilles pull it directly into the ductwork. Unlike spring pollen that gets filtered by outdoor vegetation, cedar pollen is fine enough to pass through standard filters and coat duct interiors, then recirculate on every heating cycle. A full system cleaning in January or February typically removes the buildup that’s been accumulating since the first freeze. Call (726) 600-7155 for an exact quote - estimates are free.
Yes, and it’s one of the most common problems we find in San Antonio. The flex duct attached to Lennox air handlers in unconditioned attics degrades faster than in any climate-controlled space. The inner liner cracks, insulation compresses, and mastic fails. We inspect these connections first on every Lennox job in Stone Oak, Helotes, and similar north-side builds.
Often we can. Many Lennox Elite and Signature cabinets have access panels designed for coil cleaning, and our Rotobrush and Nikro equipment allows us to clean in place when the coil is accessible and not heavily impacted. If the coil is plugged with caliche dust or biological growth, we may need to cut access or recommend pulling it - we’ll show you the camera image and give you a written price for either approach before proceeding.
We use genuine Lennox parts for proprietary components like control boards, blower motors, and iComfort zone dampers. For duct repairs - flex duct, mastic, foil tape, mechanical fasteners - we use OEM-equivalent materials that meet or exceed Lennox spec, sourced from trade-recognized suppliers. Because we’re an independent shop, we’re not restricted to Lennix-only supply chains, which often means faster turnaround and lower parts cost passed through to you.
For most San Antonio homes with Lennox equipment, every 3 to 5 years is the right interval. Homes near active construction, with multiple pets, or in the direct path of cedar pollen exposure may need cleaning every 2 to 3 years. The definitive answer comes from the camera scope - we can show you exactly what’s inside your ductwork and whether it’s time. Call (726) 600-7155 to schedule a look.
