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 Company in Seguin, TX
Air duct cleaning in Seguin typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the real cost is the local housing stock: from historic farmhouses with sagging fiberboard ductwork to tight-built new construction that depends entirely on clean ducts for breathable air. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Seguin from our San Antonio office. Call (361) 326-5060 for a written estimate before any work starts.
Why Seguin Homes Are Different
Seguin’s historic central neighborhoods were built on a grid of pecan orchards and cotton fields, and homes there still draw pollen and pecan aphid honeydew through HVAC returns at levels that would be unrecognizable in nearby San Antonio or New Braunfels. That makes duct cleaning a seasonal health necessity rather than a luxury.
The housing stock swings hard by era. Around the Guadalupe County Courthouse square, 1920s – 1950s bungalows and farmhouses often run on original galvanized supply trunks or early flex duct with multiple unsealed joints that trap debris. In the Highland Park and Woodlake subdivisions, 1970s – 1990s ranch homes have aging ductboard that sheds particulates. The 2010s – 2020s subdivisions on the west side along Highway 123 are tight-built and energy-efficient, but that means every contaminant stays inside unless the ducts are clean.
In the older neighborhoods near the Guadalupe River, we regularly find 1950s-era fiberboard ductwork under pier-and-beam floors that has sagged from decades of humidity, creating low spots where debris and moisture collect and mold blooms. That condition almost never appears in Seguin’s newer slab-on-grade west-side homes. The humid subtropical climate here means HVAC systems run 8 – 10 months a year, so ducts accumulate dust, pollen, and condensation-related microbial growth faster than in drier Texas cities. February through April, the pecan and oak pollen season floods our phone lines.
Our Main Seguin Services
Seguin homeowners call us for three core jobs, each handled with The Garrison Standard: written price, written guarantee, crew accountability.
Air Duct Cleaning in Seguin
We clean the full supply and return system with a Rotobrush rotary brush system or Nikro negative-air machine, depending on duct material and contamination level. In Seguin’s older homes near the river, we often start by assessing whether sagging fiberboard sections need replacement before cleaning can be effective. Every job gets a written price upfront and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Seguin details our full process.
Dryer Vent Cleaning in Seguin
Lint buildup in dryer vents is a leading cause of house fires, and Seguin’s long hot season means dryers work overtime. We pull the full lint column with professional-grade equipment, inspect the exterior termination for proper airflow, and verify the run meets code. Background-checked, uniformed technicians handle every call. Dryer Vent Cleaning in Seguin covers what we check and why it matters.
Duct Sealing in Seguin
Unsealed joints in Seguin’s older galvanized or flex duct systems leak conditioned air into attics and crawl spaces, driving up bills and drawing in humidity. We apply duct sealing mastic and mechanical fasteners to close gaps, then pressure-test the system to confirm results. Tight-built west-side homes especially benefit, since any leak is a direct hit on efficiency. Duct Sealing in Seguin explains our sealing protocol.
