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.
Trane Air Duct Cleaning in Houston, CA | Hollis Air Duct Cleaning
Air Duct Cleaning - Houston for a typical Trane single system runs $425 to $780, and on a two-story home with two air handlers you’re looking at $680 to $1,150. The single biggest factor in Houston isn’t dust, it’s the humidity that keeps duct interiors wet nine months out of the year, so we approach Trane systems here as a biological cleanup, not a vacuum job. We’re an independent Trane service provider serving Houston with written pricing before we touch anything. Call (361) 326-5060 for a free estimate.
Why Houston Residents Choose Us for Trane Service
We’ve worked on Trane residential equipment in Houston long enough to know which parts of these systems fail here first. Roy Castellanos, our owner, came up through the Los Angeles Trade-Technical College sheet metal and air conditioning program and spent years doing hands-on duct work before starting Hollis. That means when we open a Trane air handler in a Houston attic, we’re not guessing at what we’re looking at.
We handle the Trane XR, XB, XLi, and variable-speed XV lines, and we understand how each one behaves in this climate. The XB series builder-grade systems that went into so many 1990s and 2000s Houston tract homes have a specific set of weaknesses we look for every time. The XV variable-speed units sweat differently than single-stage equipment, and we adjust our cleaning approach accordingly. For full details on what we do across the brand, see our Trane sales & service page.
Every Houston job gets a written price before work starts, background-checked and uniformed technicians, and our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge. That’s The Garrison Standard, and it applies to every Trane system we touch in Houston.
Common Trane Air Duct Cleaning Problems We Solve in Houston
- Musty odor from biofilm on Trane all-aluminum evaporator coils. Trane XR and XB systems run 9 to 10 months a year in Houston, and the coil never really dries out. Condensate pan biofilm builds up fast, and that smell travels straight through the supply ducts into living spaces. Cleaning the coil and treating the pan is part of our full system cleaning.
- Mold substrate in flex duct from 130°F+ attic heat. Houston attics bake. The flex duct liner in a slab-on-grade ranch or two-story home absorbs humidity every time the AC cycles off, and standard vacuum-only duct cleaning won’t kill what grows in that liner. We use negative-air extraction and, where the liner is saturated, replacement.
- Return-side air leaks from mastic shrinkage. Trane cabinet and plenum connections in Houston attics get sealed with mastic that shrinks in the heat. Cracks open up, and humid attic air gets pulled straight into the supply stream. We seal those leaks with fresh mastic so the air moving through the system is actually conditioned air, not attic air.
- Wet supply ducts on Trane XV variable-speed systems. The slow ramp-down on XV air handlers leaves the indoor coil and the first 10 to 15 feet of supply duct wet longer than a single-stage system would. In Houston’s dew point conditions, that’s enough time for biological growth to take hold. We account for this when cleaning variable-speed Trane equipment.
- Post-storm contamination. After a hurricane or tropical storm, Houston homeowners ask one question: did water get into the ducts? We offer a post-storm duct inspection in Houston that checks for standing water, debris, and mold growth in the duct runs and at the plenum.
Trane Service in Houston: What Local Conditions Mean for Your Equipment
Houston’s summer dew points sit in the mid-70s, and that single fact shapes every Trane duct cleaning job we do here. When a Trane system cycles off, the cold coil and the nearby flex duct interior drop below the dew point and sweat. In Dallas or Austin, winter temperatures give the system a genuine dry reset. Houston doesn’t get that. The mild winters mean mold and biological growth stay active through the year, so a duct interior in a Meyerland or Sharpstown home never actually dries out. That’s why we treat Trane duct cleaning in Houston as a remediation job as much as a cleaning job. The all-aluminum Trane coil, the flex duct liner, the plenum connection points, all of it stays damp in a way that a generic duct cleaning company from a dry climate won’t understand. We do.
Trane Models & Products We Service in Houston
We service the full range of Trane residential and light-commercial equipment found in Houston homes: the XR series (XR14 and XR16 split systems), the XB builder-grade units common in 1990s and 2000s construction, the XV variable-speed and communicating systems (XV18 and XV20i), and older XLi and Weathertron-era equipment still running in Houston ranches. For filters and door gaskets, we use OEM Trane parts where they exist. For flex duct, mastic, and insulation on the duct side, we use quality aftermarket materials because there’s no reason to pay Trane markup on commodity flex. If a Trane coil is pitted or mold-saturated past cleaning, we tell you plainly it’s a replacement decision, not a duct cleaning decision. Our Houston coverage extends across the full Houston service area.
Trane Service Pricing in Houston
For a single Trane system in Houston, our Dryer Vent Cleaning in Houston is separate, but full duct cleaning runs $425 to $780. Two systems in a two-story home run $680 to $1,150. Evaporator coil cleaning is typically $180 to $340 when bundled with duct cleaning. Duct sealing runs $300 to $600 per system depending on how many plenum connections and duct runs need resealing. What drives the price is the number of supply and return runs, the condition of the flex duct liner, and whether the coil needs biological treatment. We write the price down before any work begins, and that price does not move at the door. Call (361) 326-5060 for a free estimate on your Houston Trane system.

FAQs – Trane Air Duct Cleaning in Houston
The most common reason is biofilm on the Trane all-aluminum evaporator coil or in the condensate pan. A vacuum-only duct cleaning won’t touch the coil or pan, so the odor source stays in place while the ducts get cleaned around it. We always clean the coil, treat the pan, and inspect the first several feet of supply duct where coil moisture travels.
Yes. The XR and XB systems in Houston run for 9 to 10 months a year, and the all-aluminum coils develop condensate pan biofilm faster than other coil types in humid conditions. The duct cleaning approach has to include coil cleaning and pan treatment, not just brushing the duct interior. If we skip that step, the odor returns in a few weeks. Call (361) 326-5060 and we’ll explain what your specific system needs.
Check whether water entered the duct runs, the air handler cabinet, and the plenum connections. Flood water sitting in flex duct liner becomes a mold problem within days in Houston’s humidity. We do a post-storm inspection in Houston that checks for standing water, liner saturation, and mastic failure at the plenum, then gives you a written report of what we found and what it costs to fix.
Yes. The XV series ramps the blower down slowly, which leaves the indoor coil and the first 10 to 15 feet of supply duct wet longer than a single-stage XR or XB system. In Houston’s dew point conditions, that extended wet window is enough for biological growth to take hold faster. We account for this when cleaning XV equipment and inspect those first supply runs carefully.
Yes. We use mastic that’s rated for high attic temperatures and apply it at every plenum connection and duct joint we open. The mastic that originally sealed many Houston Trane systems shrinks and cracks in the attic heat, pulling humid air into the supply stream. We scrape the old mastic and reseal with a product that holds in this climate. For an exact cost on your system, call (361) 326-5060.
