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.

AfterAir Duct Cleaning in Seguin, TX
Complete HVAC cleaning in Seguin typically runs $380-$620 for a whole-home system, with air quality and sanitizing treatments adding $180-$340 depending on whether mold, bacteria, or odor issues are present. The combination of heavy pecan pollen loads, Guadalupe River valley humidity, and near-continuous summer runtime from May through September means Seguin ductwork accumulates debris faster than systems in drier Hill Country towns just 40 miles west. CleanRun crews coordinate scheduling from our San Antonio office and serve Seguin homes with documented photo records on every visit. Call (830) 402-5110 for a written estimate before any work begins.
Why Seguin Homes Are Different
Seguin’s identity as the self-proclaimed “Pecan Capital of the World” is not decorative. Commercial orchards and mature shade pecans blanket the city, and the spring pollen bloom plus fall harvest debris create a particulate load that overwhelms standard HVAC filters. The material that reaches the ductwork is finer and more adhesive than ordinary dust; our technicians in west-side and north-side subdivisions regularly pull sections caked with an oily pecan-pollen film that bonds to flex-duct liner walls.
The Guadalupe River bottomlands keep relative humidity elevated year-round. Where dry dust might settle and sit, Seguin’s moist air turns debris accumulation into a mold-favorable environment inside duct runs. This is not a generic warning; it is a recurring local pattern we document in photo records.
Housing stock compounds the issue. Historic-core homes from the late 1800s and early 1900s were retrofitted with central air through chases never designed for ductwork. Mid-century ranch slabs have decades of accumulation. And the 2000s-2020s tract subdivisions built along I-10 northeast of San Antonio used builder-grade flex-duct that sags or pulls loose from boot collars after years of near-continuous summer runtime.
Our Main Seguin Services
Seguin homeowners contact CleanRun most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Seguin
We clean the full duct network, from return plenum (the sheet-metal box that collects air before it reaches the furnace) to every supply register, using negative-pressure extraction (a vacuum system that pulls debris out while agitation tools loosen it). In Seguin’s newer subdivisions, we account for the pecan-pollen film that standard brush passes can leave behind. Every run is photographed before and after. Air Duct Cleaning in Seguin has full details.
Dryer Vent Cleaning in Seguin
Lint accumulation in dryer vents is a fire hazard and extends drying cycles. We clean the full vent run from appliance to exterior termination, verify airflow with a meter, and document the before-and-after condition. Seguin’s humidity can cause lint to clump and adhere more stubbornly than in drier climates. Dryer Vent Cleaning in Seguin covers pricing and scope.
Duct Repair & Sealing in Seguin
Sagging flex-duct, disconnected boot collars, and chased-in retrofit ductwork in older homes leak conditioned air into attics and crawl spaces. We repair or replace damaged sections and seal joints with mastic or metal-backed tape, then pressure-test to verify results. Duct Repair & Sealing in Seguin explains our approach.

BeforeAfterHVAC Cleaning in Seguin
Complete HVAC cleaning in Seguin addresses the components that move and condition air but are not part of the duct network itself. The evaporator coil, blower assembly, condenser, and air handler all collect the same pecan-pollen debris that fills ducts, plus condensation that turns that debris into a microbial growth medium. CleanRun’s HVAC Cleaning service documents every component with before-and-after photos, and every quote is written before work starts under Haven Standard Clause 1.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow from registers, or the system running longer to reach set temperature.
What it costs in Seguin
Evaporator coil cleaning in Seguin typically ranges from $180 to $320.
How we do it
We access the coil through the plenum, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the full surface before reassembly.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust puffing from registers when the system cycles on.
What it costs in Seguin
Blower assembly cleaning in Seguin typically ranges from $140 to $260.
How we do it
We remove the blower motor and wheel, clean each blade and the housing interior, balance the wheel, and reinstall with torque verification.
What HVAC Cleaning Costs in Seguin
| Item | Typical range in Seguin |
|---|---|
| Evaporator coil cleaning | $180 - $320 |
| Blower assembly cleaning | $140 - $260 |
| Full HVAC system cleaning (coil, blower, condenser, air handler) | $380 - $620 |
How do I know my HVAC components need cleaning, not just my ducts?
If your ducts were cleaned recently but rooms still heat or cool unevenly, or the system runs longer than it used to, the coil or blower is likely clogged with the same debris. We inspect both during any duct cleaning quote and show you the photo evidence. Call (830) 402-5110 for a free estimate.
Can HVAC cleaning reduce my summer electric bills in Seguin?
Yes, a clean coil and blower move air more efficiently, which can reduce runtime; in Seguin’s near-continuous summer cooling season, even a 10% efficiency improvement adds up. We measure static pressure before and after to document the change. Call (830) 402-5110 for a written quote.
Air Quality & Sanitizing in Seguin
Air quality and sanitizing in Seguin targets the microbial growth that Guadalupe River valley humidity breeds inside debris-laden ductwork. The same pecan-pollen film that coats ducts provides a nutrient source for mold and bacteria, and the musty odor that results is a common complaint in Seguin homes, particularly in historic-core properties with retrofit ductwork and newer subdivisions with sagging flex-duct. CleanRun’s Air Quality & Sanitizing service treats the source, not the symptom, with documented photo records of every treated surface.
Mold Treatment
Signs you need it
Visible mold at registers, a persistent musty odor when the system runs, or recent water intrusion in the duct run.
What it costs in Seguin
Whole-system mold treatment in Seguin typically ranges from $280 to $480.
How we do it
We apply an EPA-registered fungistatic coating to affected duct surfaces after mechanical cleaning, with before-and-after photo documentation of every treated run.
UV Light Installation
Signs you need it
Recurring mold growth despite previous cleaning, or a household member with respiratory sensitivity to microbial allergens.
What it costs in Seguin
UV-C light installation in the plenum or air handler in Seguin typically ranges from $340 to $580.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the air handler to irradiate the coil and plenum surfaces continuously, with annual bulb replacement scheduled.
What Air Quality & Sanitizing Costs in Seguin
| Item | Typical range in Seguin |
|---|---|
| Mold treatment (whole system) | $280 - $480 |
| Bacteria sanitizing | $180 - $340 |
| UV-C light installation | $340 - $580 |
Is mold in my ducts really a Seguin-specific problem?
Yes, the combination of pecan pollen debris and Guadalupe River valley humidity creates conditions we do not see in drier Hill Country towns; our Seguin photo records show mold colonization in ducts that were “clean” by visual inspection two years prior. Call (830) 402-5110 for an inspection with written findings.
Does UV light actually prevent mold, or just slow it?
Properly installed UV-C at the coil and plenum prevents mold colonization on irradiated surfaces by breaking cellular bonds; it does not clean existing debris, so we always pair installation with mechanical cleaning first. Call (830) 402-5110 for a written scope and price.

FAQs About Air Duct Cleaning in Seguin
No permit is required for standard residential duct cleaning or sealing in Seguin; only structural modifications to the HVAC chase or new duct installation trigger permit requirements with the City of Seguin Development Services Department. We handle any necessary documentation if repair work crosses into permitted territory, and we note this in your written scope before starting.
We typically schedule Seguin appointments within 3-5 business days, with emergency mold treatments prioritized based on photo evidence. All calls are answered by a live person, 24/7, and we confirm your technician’s name and arrival window by text the evening before.
Yes, we regularly work in Seguin’s late-1800s and early-1900s historic core, where retrofit ductwork through original chases requires careful access planning and smaller-diameter tools.
