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, NY | CleanRun Air Duct Cleaning
CleanRun Air Duct Cleaning provides independent Air Duct Cleaning - San Antonio for Lennox systems across the area. We are not a manufacturer-authorized dealer, and we do not pretend to be. What we are is a crew that has spent years pulling cedar pollen, caliche dust, and degraded fiberglass out of Lennox ductwork in this specific market, so we know exactly what these systems accumulate here and what it takes to remove it. Call (806) 606-6902 and we will put a written price in front of you before any panel comes off.
Why San Antonio Residents Choose Us for Lennox Service
We see the same Lennox air handlers, evaporator coil designs, and aging flex-duct layouts across San Antonio week after week. That repetition is the expertise. Tomas Reyes, Owner & Lead Technician, completed his HVAC coursework at Queensborough Community College before spending years working residential and commercial duct systems, and he has built CleanRun around one rule: camera inspection first, written scope second, no work until you have seen what is inside your ducts. For Lennox owners in San Antonio, that matters because the debris these systems collect here is not cosmetic. It is a dense, compacted layer of biological material and mineral dust that restricts airflow and loads your filter faster than the manufacturer’s maintenance schedule assumes. We also have Lennox sales & service knowledge that covers the full model range, from Merit Series budget installs to Signature Series variable-speed systems.
Common Lennox Air Duct Cleaning Problems We Solve in San Antonio
- Evaporator coil biofilm binding cedar pollen. Lennox evaporator coils in attic installations sit in humid, hot air for most of San Antonio’s 9-10 month cooling season. That condensation creates a sticky biofilm on the coil surface, and when cedar fever season hits from December through February, pollen sticks to that film and builds a mat that chokes airflow. Cleaning requires coil-specific treatment, not just duct vacuuming.
- Degraded fiberglass insulation inside return plenums. Lennox return plenums in San Antonio attics routinely bake at 150°F or higher in summer. The fiberglass insulation inside degrades and sheds into the airstream, adding debris that no filter catches. We photograph this before and after so you can see the difference.
- Flex duct joints separating at Lennox supply plenums. Homes built along the US 281 and Loop 1604 corridors from the 1970s through the 2000s have slab-on-grade, attic-ducted layouts. The original flex ductwork is now 20-40 years old, and heat sag separates joints. A separated joint pulls attic insulation and dust straight into your Lennox system’s airflow.
- Variable-speed blowers shaking loose more debris. Lennox Elite and Signature Series air handlers use variable-speed blowers that ramp up to compensate for dirty filters. That creates higher static pressure, which shakes debris loose from duct walls and pushes it toward your registers. If you have a Lennox variable-speed system and you are seeing more dust on furniture, the ductwork is likely the source.
- Caliche dust embedding in Lennox duct board. Northwest San Antonio neighborhoods along Loop 1604, especially 78249 and 78250, sit on raw caliche cuts. The fine calcium-carbonate powder from construction and exposed soil gets pulled into returns and embeds in the fiberglass interior of Lennox duct board. A standard vacuum pass will not remove it. It requires negative-pressure agitation.
BeforeAfterLennox Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio has a cooling season that barely pauses. The AC runs roughly 9-10 months a year, and from December through February, cedar fever season adds a layer of Ashe juniper pollen so heavy the air visibly hazes yellow. That combination means San Antonio Lennox owners deal with a debris problem unlike anything in higher-humidity Texas markets like Houston, where organic dust dominates, which is why our HVAC Cleaning in San Antonio targets these specific layered contaminants. Here in San Antonio, the debris is layered: cedar pollen bound to evaporator coil biofilm, fine caliche dust compacted in return plenums, and degraded fiberglass from attic heat. We documented this last March in a two-story home west of JBSA-Lackland, zip 78245. A Lennox Elite Series system had a return duct packed with gritty cedar pollen and caliche dust, an evaporator coil with a gray biofilm mat, and a 12-foot flex duct section that had separated at the plenum from heat sag and was actively pulling in attic insulation. Cleaning the coil and returns was step one. Sealing the separated joint and replacing the torn outer liner was step two. The video inspection after confirmed full airflow. The photo tells you what’s in there. Everything else is just paperwork.
Lennox Models & Products We Service in San Antonio
We service the full Lennox residential range: Elite Series (SL280, XP20), Merit Series (ML180, ML14XC1), Signature Series (SLP98, XC25), and Dave Lennox Signature Collection air handlers like the CBA25UH. For parts, our stance is simple. We use OEM-equivalent or upgraded aftermarket filters, access panels, and duct components that fit the exact cabinet dimensions. If an evaporator coil replacement is unavoidable, we insist on OEM Lennox coils. For everything else, a quality aftermarket option keeps repair costs down without sacrificing fit. If an access panel is rusted or a flex section is more than 15 years old and sagging, we tell you straight and seal or replace it during cleaning rather than letting it fail next summer, and for system issues beyond ductwork we can refer you to Lennox repair in Austin specialists.
Lennox Service Pricing in San Antonio
Lennox air duct cleaning in San Antonio typically runs $450-$750 for a whole-home system, depending on the square footage, number of duct runs, and whether the evaporator coil needs dedicated cleaning. A coil-only cleaning usually runs $220-$400. Duct sealing, if joints have separated, adds $90-$180 per access point. Every CleanRun job starts with a written price before any work begins. That is not a promotional gimmick. It is Haven Standard Clause 1, and it exists because the industry’s bait-and-switch reputation is earned. You will see the camera findings, you will see the written scope, and you will see the price in writing before a single panel comes off. Call (806) 606-6902 for a free estimate with no obligation.

FAQs - Lennox Air Duct Cleaning in San Antonio
The smell is the accumulated cedar pollen and caliche dust that built up during cedar fever season and got baked into the return ducts during early spring warm spells. March is the peak for this in San Antonio because the pollen load from December through February has had months to settle and compact. A return duct cleaning with negative-pressure extraction removes that material. Call (806) 606-6902 and ask us to show you the camera footage before we start.
Yes. The fine calcium-carbonate powder from construction along Loop 1604 is abrasive. When it embeds in duct board and then breaks loose, it cycles through the blower housing and accelerates bearing wear. Lennox variable-speed blowers are expensive to replace. Cleaning the ducts and sealing the return path before that dust reaches the blower is a far cheaper fix. We will put that in writing.
It can. A coil coated in biofilm and pollen mat transfers less heat, so the compressor runs longer to hit the same thermostat setpoint. That longer runtime is measurable on your electric bill, especially in San Antonio where the cooling season stretches nine to ten months. We cannot promise a specific percentage savings, but we can show you the before and after airflow readings. Call (806) 606-6902 for an exact quote on coil cleaning, and we will include the airflow measurement in the written scope.
If the flex duct sections are original from the 1990s, they are 25-35 years old and have been baking in San Antonio attic heat the entire time. The outer liner is likely brittle, and the inner liner may have degraded enough that cleaning will not restore it. We will inspect each run with a camera and tell you which sections are worth cleaning and which need replacement. We will not sell you a cleaning on ductwork that should be replaced. That is the whole point of the photo record.
Because most basic duct cleanings in rental properties near JBSA-Lackland, especially zip codes 78245, 78227, and 78250, only vacuum the registers and never touch the return plenum, the evaporator coil, or the duct interiors. Military tenant turnover on 2-3 year PCS orders means landlords rarely trigger a maintenance review, so these systems carry a decade or more of compacted cedar pollen, caliche dust, and mold from summer condensation. A proper cleaning requires camera inspection of every run and coil-specific treatment. Call (806) 606-6902 and we will document what is actually inside before quoting a price.
