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 South Houston, TX
Air duct cleaning in South Houston runs $350 – $650 for a typical single-family home, with most jobs completed in one visit. The work here is different from standard suburban cleaning because South Houston’s heavy industrial corridor deposits a dark, sticky, chemical-laden dust that ordinary vacuums won’t touch. We’re Hollis Air Duct Cleaning, and our crews use Rotobrush rotary systems paired with heavy-duty degreasers and antimicrobial treatments built for this exact environment. Call (361) 326-5060 for a written estimate before any work starts.
Why South Houston Homes Are Different
South Houston sits in the shadow of the Houston Ship Channel and its surrounding refineries. That proximity matters inside your ducts. The particulate that settles here isn’t ordinary household dust; it’s oily, carbon-heavy, and often carries a faint chemical odor that standard cleaning methods just smear around. We’ve pulled registers in homes near Texas Avenue and found buildup that looks more like exhaust residue than typical lint and skin cells.
The housing stock compounds the problem. Most South Houston neighborhoods were built out between the 1950s and 1970s with rigid galvanized metal ductwork that wasn’t designed for today’s constant cooling loads. Those original systems run through hot attics and damp crawl spaces, pulling in humid air that lets mold colonize the same ducts carrying refinery fallout. Newer townhomes off Spencer Highway have flexible ductwork instead, but the humidity finds its way in there too, especially after the heavy rains and occasional flooding this flat, low-lying area sees.
We don’t walk into a South Houston job with the same approach we’d use in a suburban development thirty miles inland. The Garrison Standard requires us to assess what kind of contamination we’re dealing with before we quote, because the equipment and treatment change with it.
Our Main South Houston Services
These are the three jobs South Houston homeowners call us for most often. Each has its own page with full pricing, process details, and what to expect.
Air Duct Cleaning in South Houston
Our full-system cleaning covers supply and return ducts, registers, and the air handler. In South Houston, we start with a heavy-duty degreasing pass because of the industrial particulate load, then follow with rotary brush agitation from our Rotobrush system and negative-air extraction using Nikro equipment. We finish with an antimicrobial treatment where moisture has promoted mold growth. The work typically takes 3 – 5 hours for a single-story ranch. Air Duct Cleaning in South Houston has complete pricing and process details.
Dryer Vent Cleaning in South Houston
Dryer vents in South Houston clog faster than you’d expect. The same oily airborne residue that coats ductwork adheres to lint in vent lines, creating dense, stubborn blockages that restrict airflow and create genuine fire hazards. We clean the full run from dryer to exterior termination with rotary tools and high-velocity air, then verify flow rates before we leave. Most South Houston dryer vent cleanings run $120 – $200. Dryer Vent Cleaning in South Houston covers what’s included and how often to schedule.
Duct Sealing in South Houston
Leaky ducts are everywhere in South Houston’s older housing stock. We seal accessible joints and seams with mastic and reinforced tape, then pressure-test to verify the improvement. Sealing is often the right move when rooms won’t stay cool despite a running system, or when energy bills spike in summer. The work pairs well with cleaning, since we’re already accessing the plenum and trunk lines. Duct Sealing in South Houston explains when sealing makes sense versus when replacement is the honest recommendation.

What pushes South Houston prices toward the high end: heavy industrial buildup requiring extra degreasing time, mold contamination from chronic humidity, and inaccessible ductwork in slab-on-grade homes with limited crawl space. What keeps them predictable: we write the full price before touching equipment, and that number doesn’t move at your door. The 365-Day Done Right Promise covers every job in writing; if the work fails within a year, we return and make it right at no charge, including a free second visit.

FAQs About Air Duct Cleaning Company in South Houston
No permit is required for standard residential duct cleaning or dryer vent cleaning in South Houston. Duct sealing and HVAC modifications may trigger permit requirements depending on scope; we flag this during our written estimate if it applies to your job. Call (361) 326-5060 and we’ll walk through your specific situation.
Most South Houston homeowners get an appointment within 3 – 5 business days. We don’t promise same-day dispatch because duct cleaning is a scheduled, in-home service that requires proper equipment loading and crew assignment. Phones are answered by a live person 24/7, so you can book or ask questions anytime.
The chemical odor in South Houston ducts comes from ongoing external exposure, not from the ducts themselves. Our degreasing and antimicrobial treatment removes accumulated residue and kills active mold, but new particulate will settle over time. Most South Houston homeowners schedule cleaning every 3 – 5 years, with annual filter upgrades to slow redeposition. We recommend Honeywell or Aprilaire media filters rated for finer particulate capture. Call (361) 326-5060 for a maintenance schedule tailored to your home’s location and system age.
