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.
Fast, Reliable Air Duct Cleaning Across Seguin
Air duct cleaning in Seguin typically runs $380-$720 for a whole-home system and always starts with a written price before any panel comes off. We’re the crew that drives out to Seguin from our San Antonio scheduling office, and we’ve been working the river-adjacent streets, the east-side subdivisions, and the newer commuter tracts long enough to know what the housing stock here actually delivers into the ductwork.
Seguin sits at a convergence point: eastern-edge cedar pollen loads from the Ashe juniper belt, Gulf humidity pushing up the Guadalupe River corridor, and a housing inventory that spans pre-WWII downtown conversions through 1970s-1990s tract homes with original duct systems that have never seen a professional cleaning. That combination produces a contamination pattern - allergen settle followed by microbial bloom - that higher-ground metros in the San Antonio-Austin corridor simply don’t experience in the same sequence. Our crews know to probe for it. Call (830) 549-6847 and we’ll put a written estimate in your hand before any work starts.
Why CleanRun Air Duct Cleaning New Braunfels Is Seguin’s Preferred Air Duct Cleaning Company
We’ve served Seguin homeowners since our founding in 2013, and the 52,000+ homes in our record all share two things: a written price agreed before work began, and a documented photo record of every duct run delivered at job completion. That includes the pier-and-beam homes near the Guadalupe River bend where flood moisture intrudes into subfloor cavities, and the 1980s tract houses on the east side where deteriorating fiberglass liner sheds into the airstream.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The equipment roster includes Rotobrush agitation systems, Nikro negative-pressure extractors, and Honeywell and Aprilaire air quality components. Customers can look up every brand independently before agreeing to a price.
The 365-Day Done Right Promise applies to every Seguin job in writing, not as a verbal assurance. If the work isn’t right, we make it right. No manager approval required. We also offer a Free Second Opinion on any competitor’s written estimate - bring us the paper and we’ll put our number next to it.
All calls are answered by a live person, 24/7, and scheduling is coordinated from our San Antonio office with crews dispatched to Seguin directly.
Our Air Duct Cleaning Services in Seguin

Residential Duct Cleaning
Seguin’s residential mix demands different approaches depending on where you live. Downtown homes near Courthouse Square with early forced-air conversions often contain oversized metal plenums with deteriorating fiberglass liner - material that sheds particulate into the airstream once the adhesive fails. Newer subdivisions on the outer edges, built for Austin-San Antonio commuters, typically have cleaner flex-duct systems but may still harbor construction debris and cedar pollen from their first few seasons. Our residential cleans include full register removal, agitation of every supply and return duct, and negative-pressure extraction so debris leaves the house entirely rather than resettling.

Commercial Duct Cleaning
Seguin’s commercial base - medical offices along King Street, retail along Court Street, industrial facilities near the highway corridors - runs systems that accumulate load faster than residential due to operating hours and occupant density. We quote commercial jobs with the same written-price protocol: scope documented, price fixed, no per-vent add-ons. Our crews work after-hours to avoid disrupting operations, and every job concludes with the standard photo record showing before-and-after condition of each duct run.

Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Seguin they often carry more than temperature - cedar pollen from December through February, mold spores from damp crawl spaces in spring, and ordinary dust load compounded by the area’s clay-heavy soils. We remove each supply register, mechanically agitate the full run with Rotobrush tools, and extract under negative pressure so nothing blows back into the living space during the process.

Return Duct Cleaning
Return ducts pull air back to the air handler, and they’re the primary collection point for airborne contaminants. In Seguin’s river-adjacent homes, returns are where we most often find evidence of moisture intrusion - musty odors, discolored flex duct, or visible mold at the plenum connection. We inspect every return with a camera before quoting cleaning, because a saturated flex run needs source removal, not just vacuuming. This is where our Air Duct Cleaning team spends extra time on Seguin jobs.

Full System Cleaning
A full system clean addresses supply ducts, return ducts, the plenum (the central distribution box), and the air handler cabinet - the complete path air travels. In Seguin’s 1970s-1990s homes, this is often the first time these components have been opened and inspected. We find deteriorating liner, disconnected flex runs, and occasionally rodent intrusion in pier-and-beam crawl spaces. The full system scope lets us catch these issues before they become bigger problems, and the photo record documents every finding.

Video Inspection
We run a camera through the ductwork before quoting any Seguin job. The video shows you what we see - debris buildup, moisture damage, liner deterioration, or collapsed flex - so the scope and price are based on documented evidence, not assumptions. For 1960s-1990s tract homes on Seguin’s east and south sides, this step is non-negotiable: original fiberglass liner in these homes is reaching end of life, and cleaning without inspecting first can release material into the airstream.

AfterTrusted Brands We Service in Seguin
Our equipment roster includes professional-grade tools from Nikro, Honeywell, Aprilaire, and Abatement Technologies - brands customers can research independently before agreeing to a price. We don’t use shop-vacs or consumer-grade extractors. The Nikro negative-pressure systems we deploy on Seguin jobs are the same units specified in NADCA cleaning standards, and our Honeywell and Aprilaire air quality components integrate with existing HVAC systems for whole-home filtration upgrades when the ductwork is clean enough to support them. Parts for common Seguin installations are stocked locally, so if a video inspection reveals a compromised duct run that needs replacement, turnaround is measured in days, not weeks.
Common Air Duct Cleaning Problems We See in Seguin Homes

- Flood-moisture intrusion in river-adjacent neighborhoods. Homes near the Guadalupe River bend on Seguin’s north side experience periodic high-water events that force moisture into subfloor duct cavities. The result is collapsed or discolored flex duct, musty odors at registers, and mold colonization behind years of ordinary dust accumulation. Standard cleaning without a mold assessment first misses the actual problem.
- Cedar pollen loading in return systems. Seguin’s position at the eastern edge of the Ashe juniper belt means December through February brings some of the heaviest cedar pollen counts in Texas. That pollen settles into return ducts and air handler cabinets, then gets redistributed each time the system cycles. A surface wipe won’t remove it; mechanical agitation and negative-pressure extraction will.
- Deteriorating fiberglass liner in 1960s-1990s tract homes. The east and south side subdivisions built during this era used fiberglass-lined metal duct or early flex duct with adhesive-bound liner. After forty-plus years, that liner delaminates and sheds visible fibers into the airstream. Cleaning without video inspection risks accelerating the release.
- Construction debris in newer commuter subdivisions. Seguin’s rapid growth has produced homes built quickly for Austin-San Antonio corridor demand. We’ve found drywall dust, wood chips, and even discarded lunch wrappers in duct systems that were never properly protected during construction and never cleaned before occupancy.
Pricing for Air Duct Cleaning in Seguin, TX
A typical residential full system cleaning in Seguin runs $380-$550 for a single-system home up to about 2,500 square feet, and $520-$720 for larger homes or systems with multiple air handlers. Commercial jobs start around $680 and scale with system complexity and access conditions. Video inspection is included in the estimate process; there’s no separate charge to look before we quote.
What moves a Seguin job toward the higher end: deteriorating liner requiring careful handling, collapsed flex duct needing replacement, or mold contamination requiring source removal rather than standard cleaning. What doesn’t affect price: number of vents. We price per system, not per register, so the written quote you receive is the full scope - Haven Standard Clause 1.

FAQs - Air Duct Cleaning in Seguin

Because flood moisture from periodic river-rise events intrudes into subfloor cavities and air handler closets, creating mold colonization in duct runs that standard vacuuming won’t address. In a 1970s pier-and-beam home near the river bend on Seguin’s north side, our crew once found collapsed flex duct with visible discoloration - not routine dust - that would have been redistributed throughout the house if we’d cleaned without replacing the compromised run first. A mold assessment identifies whether source removal is needed before any agitation begins. Call (830) 549-6847 for a free inspection and written quote.
Yes - Seguin sits at the eastern edge of the Ashe juniper belt, and December through February pollen loads are among the heaviest in Texas. That pollen enters through return grilles, settles in duct runs and air handler cabinets, and gets redistributed with each system cycle. We see the accumulation on camera inspections every March and April, and mechanical agitation with negative-pressure extraction is the only method that removes it rather than pushing it deeper. Call (830) 549-6847 to schedule a post-season clean with documented before-and-after photos.
A real duct cleaning mechanically removes debris from every duct run using agitation tools and negative-pressure extraction, with photo documentation of the results. A fogging ‘sanitiser’ sprays a chemical mist into the ducts without removing the source material - it’s the equivalent of deodorizing a dirty carpet instead of extracting the soil. In Seguin’s moisture-prone river-adjacent homes, fogging is particularly misleading: it doesn’t remove mold from a saturated flex run, and the moisture in the fog can actually worsen the problem. We don’t sell fogging as a standalone service, and we’ll tell you when source removal is needed instead. Call (830) 549-6847 for an honest scope and written price.
Expect significant debris accumulation and possible material degradation. Seguin’s 1970s-1990s housing stock on the east and south sides often contains original fiberglass liner that has reached end of life, plus flex duct that may be collapsed or disconnected in crawl spaces. We start with a video inspection to document condition before quoting any work. The photo record becomes your baseline for deciding whether cleaning is sufficient or whether duct repair or replacement is the smarter investment. Written price before work starts, every time. Call (830) 549-6847 to schedule.
Every three to five years for most Seguin homes, with two local exceptions: homes near the Guadalupe River should be inspected after any flood event that reaches the foundation, and households with cedar pollen sensitivity often benefit from annual post-season cleaning (March-April) to remove the accumulated allergen load. The 1960s-1990s tract homes with original liner may need more frequent inspection as that material deteriorates. We don’t sell maintenance contracts or push unnecessary frequency - the video inspection tells you what the ducts actually need. Call (830) 549-6847 for a free assessment and written recommendation.
