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 Houston
Air duct cleaning in Houston typically runs $350-$650 for a complete residential system, with most homes falling in the $450-$550 range depending on duct material, accessibility, and whether flood or mold remediation is needed. Our crews dispatch from the Houston office and carry Rotobrush agitation systems, Nikro negative-air extractors, and Abatement Technologies HEPA containment on every truck. Call (469) 972-3151 for a written estimate before any work begins.
We’ve worked in Houston long enough to know the difference between a 1968 ranch in Spring Branch with original fiberglass duct board and a post-Harvey replacement system in Meyerland. That matters because the cleaning approach changes completely. Houston’s subtropical humidity, year-round cooling season, and attic temperatures that cook flex duct to brittleness create contamination patterns you won’t find in drier cities. Our Air Duct Cleaning team treats Houston jobs as biological remediation first, dust removal second.
Why Kestrel Air Duct Cleaning Is Houston’s Preferred Air Duct Cleaning Company
Homeowners in Sharpstown, Westbury, and the Energy Corridor call us because we’ve built a local reputation on one thing: doing what we said we’d do, at the price we wrote down, with a guarantee that has teeth. The Kingswell Guarantee, which governs every Kestrel job, requires four things in writing - the price before work starts, a defined arrival window, a clean job site, and a written promise to return free if the work fails within the guarantee period. No exceptions.
Our Houston customers aren’t guessing whether we’ll show up. Our calls are answered by a live person, 24 hours a day. Our technicians are background-checked, uniformed, and trained on the specific failure modes of Houston housing stock: brittle duct board, crushed flex runs behind slab-on-grade chases, and mold root systems that regrow if source removal isn’t thorough. Dale Whitmore, who leads Kestrel Air Duct Cleaning, insists that every Houston job gets camera verification so the homeowner sees what came out and what condition the ducts are in now.
Dispatch and scheduling are coordinated from our Houston office, and crews serve Houston locally. That means we’re not routing trucks from Conroe or Sugar Land and hoping they hit the window. We know which neighborhoods built out in the 1970s still run original duct board, which blocks in Braeswood took water in both Allison and Harvey, and why a supply register sweating in August isn’t a cosmetic issue - it’s a symptom of failed insulation and biological growth inside the plenum.
HVAC Duct Cleaning in Houston
HVAC Duct Cleaning in Houston addresses the complete forced-air system: supply trunk and branches, return pathways, air handler cabinet, blower assembly, and plenum connections. Because Houston’s cooling season effectively runs March through November, HVAC systems never get an extended shutdown that allows duct interiors to dry and self-regulate; moisture-laden return air is pulled through ducts almost year-round, sustaining the damp conditions mold and dust mites require. A typical residential HVAC duct cleaning in Houston runs $450-$650 for a full system, with commercial or multi-zone residential systems starting around $800.
Supply Duct Cleaning
Supply ducts carry conditioned air from the air handler to your rooms. In Houston, we regularly find supply registers sweating condensation in summer - a visible symptom that signals failed duct insulation and biological growth inside the plenum. Our Rotobrush rotary brush systems dislodge debris at the duct wall, while Nikro negative-pressure units pull contaminants out before they re-enter the living space.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. These run wetter in Houston than almost anywhere else in the country. We inspect return plenums for mold root systems embedded in aged duct board, because surface cleaning without source removal means regrowth within one summer cycle.
Vent Cleaning in Houston
Vent Cleaning in Houston focuses on the terminal registers, grilles, and the immediate duct runs behind them - the parts homeowners see and touch. In Houston’s post-war housing stock, especially the slab-on-grade ranches built from the 1960s through 1980s, vent cleaning often reveals disconnected or crushed flex runs that have never carried proper airflow since installation. A typical vent cleaning service in Houston, when done as part of a full system cleaning, runs $75-$150 per zone; standalone vent cleaning for surface contamination starts around $200 for a standard three-bedroom home.
Register and Grille Restoration
We remove each register, clean the face and blade assembly, and treat for the biofilm that builds up in Houston’s humidity. This isn’t cosmetic. Stained registers indicate upstream contamination that will recirculate as soon as the blower kicks on.
Video Inspection of Vent Runs
Every vent cleaning includes camera inspection of the first several feet of duct behind the register. In Westbury and Sharpstown, we’ve found flex duct pinched behind joist chases, completely blocking airflow to back bedrooms. Homeowners thought they had a dirty vent. They had a disconnected duct run bleeding conditioned air into the attic.
Trusted Brands We Service in Houston
Our trucks carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products for Houston homeowners who want to maintain clean air between service visits. We don’t upsell equipment you don’t need, but we do stock replacement media and upgrade components locally so there’s no two-week wait for a specialty filter. If your system needs a UV light upgrade to control biological growth in Houston’s humid conditions, we’ll specify the right Aprilaire or Honeywell unit for your air handler size and give you the installed price in writing before we touch the equipment.
Common Air Duct Cleaning Problems We See in Houston Homes
- Mold root systems in aged duct board. Houston’s average relative humidity stays above 75-80%, among the highest of any major U.S. city. In 1970s Spring Branch homes with original fiberglass duct board, we regularly find mold colonies that have penetrated the porous material. Surface cleaning leaves the root system intact; it regrows within one Houston summer.
- Crushed or disconnected flex runs behind slab chases. The city’s post-war building booms produced vast tracts of slab-on-grade ranches where flex duct was routed through tight joist chases. In Sharpstown and Westbury, our cameras reveal runs pinched during original construction, never carrying airflow. Half the system leaks into the attic while the homeowner pays to cool it.
- Flood silt and unreplaced insulation in formerly inundated neighborhoods. In Meyerland, Braeswood, and stretches of the Energy Corridor that took water in Tropical Storm Allison and Hurricane Harvey, homeowners mitigated visible damage but never opened the duct system. We pull back sections to find embedded silt lines and insulation batting that stayed wet for weeks.
- Brittle inner liners shedding glass fibers. Flex duct routed through Houston attics that hit 140°F+ in summer bakes fiberglass duct board until its inner liner shatters. The system still “works” - it just distributes glass fibers and mold spores through every supply register. Supply registers sweating condensation are the tell.
Pricing for Air Duct Cleaning in Houston, TX
Most Houston homes run between $450 and $550 for a complete residential air duct cleaning, with smaller condos or townhomes sometimes falling to $350 and larger homes with multiple zones or commercial-grade equipment running to $650. Commercial duct cleaning in Houston starts around $800 and scales with system complexity. What moves you within that range: duct material (duct board takes longer than metal), accessibility (crawl space vs. attic), contamination severity (mold remediation requires HEPA containment and longer cycle times), and whether we find crushed or disconnected runs that need repair.
We give one flat price per system, agreed in writing before a single vent is touched. No per-vent pricing. No door-step revisions. The price we write is the price you pay. Call (469) 972-3151 for a free estimate - we’ll ask about your home’s age, neighborhood, and any symptoms you’ve noticed, then give you a range you can plan around.

FAQs About Air Duct Cleaning in Houston
Yes. Sweating supply registers in Houston mean the duct insulation has failed and the metal register is cold enough to condense moisture from our humid air. That same failed insulation allows biological growth inside the plenum, which then distributes through the system. We inspect the plenum and trunk connections, clean the contaminated areas, and re-insulate where needed. Call (469) 972-3151 for an exact quote - estimates are free.
It depends on the liner condition. If the inner fiberglass surface is intact, we can clean it with controlled brush agitation and negative-air extraction. If the liner has shattered from decades of attic heat - common in Westbury - we document it with camera footage and give you replacement options before we proceed. We don’t clean duct board that’s shedding fibers into your air. Call (469) 972-3151 and we’ll inspect it.
Yes, for two reasons. Houston’s 9- to 10-month cooling season means moisture-laden return air cycles through ducts continuously, never allowing a dry-out period that would suppress mold and dust mites. And our humidity levels, consistently above 75-80%, create biological growth conditions that drier Sun Belt cities simply don’t face. Duct cleaning here is remediation, not just maintenance. Call (469) 972-3151 for an exact quote - estimates are free.
Expect to find embedded silt lines, mold root systems in duct board, and insulation batting that stayed wet for weeks after the visible water receded. We open the plenum and inspect with cameras before we quote any work. If flood residue is present, standard cleaning won’t suffice - we specify remediation-level cleaning or replacement of affected sections, with the scope and price in writing before we start. Call (469) 972-3151 for an exact quote - estimates are free.
It means we use source-removal methods: mechanical brush agitation to dislodge debris from duct walls, negative-air extraction to capture it at the point of disturbance, and HEPA filtration to prevent recontamination of your living space. We don’t just vacuum the register face. We clean the entire system, camera-verify the results, and put the 365-Day Done Right Promise in writing. If the work falls short within that period, we return and make it right at no charge. Call (469) 972-3151 for an exact quote - estimates are free.
