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.

AfterFast, Reliable Air Duct Cleaning Across Seguin
Air duct cleaning in Seguin typically runs $380-$680 for a full residential system, and every job starts with a written price before we touch a single panel. We’re CleanRun Duct Repair & Cleaning, and our crews serve Seguin from our San Antonio dispatch office, with scheduling coordinated for the Guadalupe County market. If your home sits near the pecan orchards off Highway 46, on a rural route outside city limits, or in one of the newer subdivisions along West Kingsbury Street, the particulate load inside your ductwork is different from what San Antonio homes experience. We account for that in how we scope the work, what equipment we bring, and what we tell you to expect. Call (830) 402-5110 for a free written estimate.
Why CleanRun Air Duct Cleaning Schertz Is Seguin’s Preferred Air Duct Cleaning Company
We’ve been in this trade since 2013. Every one of the 52,000+ homes we’ve served got a written price before work started and a documented photo record when the crew left. That hasn’t changed for Seguin.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We don’t send day laborers or subcontractors you can’t trace.
The 365-Day Done Right Promise applies here exactly as it does everywhere else we work. If the work isn’t right, we make it right. It’s in writing on every job, not just stated in marketing copy.
We’re familiar with Seguin’s housing stock: the historic-core homes near Court Street with chases retrofitted for central air, the mid-century slabs around Kingsbury, and the 2000s-2020s tract developments that filled in as I-10 growth pushed northeast from San Antonio. Each type presents different duct problems, and we scope accordingly.
Our Air Duct Cleaning Services in Seguin
Residential Duct Cleaning
Most of our Seguin calls are for single-family homes, and the work varies significantly by location. A ranch on a paved street near Seguin High School presents different challenges than a place on a rural route with a quarter-mile of caliche driveway kicking up dust that the return ducts pull straight inside. For orchard-belt and rural properties, we typically recommend cleaning every 18 to 24 months rather than the generic 3-to-5-year interval you’ll see on national sites. The pecan pollen loading is real, and standard HVAC filters don’t catch the fine, oily fraction that bonds to duct walls.
Commercial Duct Cleaning
Seguin’s commercial base includes downtown retail on Court Street, medical offices near the hospital district, and light industrial along Highway 123. We clean commercial systems under the same H.A.V.E.N. Standard as our residential work: written scope, written price, documented photo record. Commercial jobs in Seguin often require after-hours scheduling, and we coordinate that through our San Antonio office without charging overtime premiums for standard evening or weekend slots.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Seguin’s newer west-side subdivisions, we regularly find supply runs caked with that fine, oily pecan-pollen dust that bonds to flex-duct liner walls. A standard brush pass alone won’t remove it. We use agitation tools under negative-pressure extraction (suction that pulls dislodged debris into a sealed containment system, not back into your house) with HEPA filtration to actually clear the liner surface.
Return Duct Cleaning
Return ducts pull air back to the handler, and they’re the entry point for most of what accumulates inside a Seguin system. Homes near unpaved roads or open land see heavier loading. We photograph every return run before and after, and the photo record is included as a standard deliverable on every job - not an upsell.
Full System Cleaning
This is what most Seguin homes actually need. Full system cleaning covers supply ducts, return ducts, the plenum (the distribution box where air splits to individual runs), registers, and the air handler cabinet. In Seguin’s humid climate, debris accumulation inside the plenum and handler can support mold growth that isolated duct cleaning won’t address. We scope the full system and quote it as a single flat price per system, not per vent.
Video Inspection
Our Air Duct Cleaning team carries camera equipment on every truck. Video inspection lets us show you what the inside of your ductwork actually looks like before we quote, and verify the results after we finish. In Seguin’s historic-core homes with retrofitted chases, camera inspection is often essential to locate where the duct run is accessible and where it isn’t. The footage becomes part of your documented job record.

BeforeAfterTrusted Brands We Service in Seguin
We work with equipment from Rotobrush, Nikro, Honeywell, and Aprilaire - brands you can look up independently to verify specifications. Our trucks carry common replacement components for these systems so Seguin customers aren’t waiting on parts shipments for standard repairs. If your ductwork includes Honeywell electronic air cleaners or Aprilaire media filters, we factor that into our cleaning protocol and can advise on whether the filter housing needs attention as part of the scope.
Common Air Duct Cleaning Problems We See in Seguin Homes
- Pecan-pollen film that brush-only passes can’t remove. The fine, oily dust from Seguin’s thousands of pecan trees bonds to flex-duct liner walls differently than ordinary dirt. Standard brush passes leave a visible film that continues trapping moisture and producing musty odor. We see this failure mode regularly in homes that had “cheap clean” work done elsewhere.
- Sagging builder-grade flex duct in newer subdivisions. The 2000s-2020s tract homes on Seguin’s west and north sides were built with flex duct run near-continuously through brutal Central Texas summers. After years of thermal cycling, the duct sags between supports and pulls loose from boot collars, dumping conditioned air into attics. Cleaning can’t fix a disconnected run - we flag it during camera inspection and can repair under the same written price protocol.
- Undersized, leaky chases in historic-core homes. The late-1800s and early-1900s homes near Court Street and the historic district had central air retrofitted through chases never designed for ductwork. These chases leak at seams and junctions, and source-removal equipment can’t reach the full duct run without targeted access work. We photograph the limitations and explain what’s reachable before quoting.
- Mold-favorable conditions from Guadalupe River humidity. Seguin’s relative humidity runs higher than drier Hill Country towns just 40 miles west. When pecan-pollen debris accumulates inside ductwork, the moisture trapped in that film supports mold colonization faster than in comparable systems elsewhere. This isn’t a generic talking point - we document it with camera evidence on jobs where it’s present.
Pricing for Air Duct Cleaning in Seguin, TX
Here’s what air duct cleaning costs in the Seguin market:
- Full residential system cleaning: $380-$680
- Supply-duct-only cleaning: $220-$340
- Return-duct-only cleaning: $180-$280
- Video inspection with written report: $120-$180 (credited toward cleaning if you proceed)
- Commercial system cleaning: quoted per system after on-site scope
These are whole-system ranges, not per-vent teaser prices. What moves a job within the range: system size (number of duct runs, not number of vents - a single duct run can serve multiple vents), accessibility (crawl space vs. attic vs. conditioned space), and contamination level (standard dust loading vs. heavy pecan-pollen buildup requiring extended agitation time). Rural properties on longer drives from our dispatch point may carry a modest trip charge, which we disclose in writing before you commit.
Every price is delivered in writing before work starts - Haven Standard Clause 1. No exceptions. No “call for a quote” bait-and-switch. Bring a competitor’s written estimate and we’ll provide a Free Second Opinion, our number next to theirs.

FAQs - Air Duct Cleaning in Seguin
Every 18 to 24 months, not the generic 3-to-5-year interval. The pecan pollen loading and caliche road dust in rural Seguin properties overwhelm standard filtration and bond to duct walls faster than in urban San Antonio neighborhoods. Homes with wood heat or propane furnaces as secondary systems may need the shorter end of that interval due to additional combustion particulate. Call (830) 402-5110 and we’ll scope your specific situation in person - estimates are free.
The combination of pecan-pollen debris and elevated humidity from the Guadalupe River valley creates mold-favorable conditions inside ductwork that drier Hill Country systems don’t experience. The pollen film traps moisture; mold colonizes the liner surface; the HVAC system distributes the metabolite odor every time it cycles. San Antonio’s slightly drier air and lack of dense orchard particulate means the same contamination level doesn’t produce the same odor. We confirm mold presence with camera inspection and address it as part of full system cleaning, not with chemical fogging that masks the symptom.
Not reliably. On a 2000s tract home off West Kingsbury Street on the west side, our tech pulled supply and return ducts that were caked with fine, oily pecan-pollen dust bonded to the flex-duct liner walls. A standard brush pass left a visible film, so we switched to agitation tools under negative pressure with HEPA filtration, then ran camera inspection to confirm the liner was clean. The homeowner said the musty smell that had lingered every summer finally cleared. Brush-only cleaning is often the reason Seguin customers call us after a “cheap clean” elsewhere failed to solve the problem.
MERV 11 to 13, provided your air handler can handle the static pressure. The fine fraction of pecan pollen that causes duct problems is in the 10-20 micron range, which MERV 8 catches poorly. However, higher MERV filters restrict airflow; in Seguin’s near-continuous summer runtime, that can stress older blower motors. We check your system’s filter rack and blower specs during our pre-work inspection and recommend the highest rating your equipment can support without damage. Filter changes every 60-90 days during pollen season are more important than chasing the highest MERV number.
Yes - significantly. In Seguin’s climate, the air handler cabinet and blower wheel accumulate the same pecan-pollen debris and humidity-driven mold as the ducts. Cleaning ducts alone and leaving a contaminated blower means the system recirculates particulate from the handler into “clean” ductwork on the first cycle. Our Full System Cleaning includes the air handler cabinet, blower assembly, and plenum as standard scope, quoted as one flat price. We photograph the blower before and after so you can see the difference. Call (830) 402-5110 for a written estimate.
