Fast, Reliable Air Duct Cleaning Across Houston
Air duct cleaning in Houston typically runs $350–$850 for a full residential system and is usually completed in 3–5 hours with same-day scheduling available. We serve Houston homeowners from the Ship Channel to the Energy Corridor, with our Air Duct Cleaning team routinely reaching Montrose, the Heights, and Memorial within 45 minutes of a call. Houston’s Gulf Coast humidity and marathon AC season create duct problems you won’t find in drier cities — microbial growth, flood contamination, and corroded connections that demand more than a basic vacuum-and-brush job. Call (855) 683-5929 for a free estimate and we’ll scope your system with a video inspection before we quote.
Why Lone Star Air Duct Cleaning Service Houston Is Houston’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Houston one job at a time — 433 verified reviews averaging 4.9 stars, with homeowners from Bellaire to Aldine specifically mentioning that owner Scott Gray showed up as the lead technician, not a subcontractor they’d never met. That’s our standard: owner-led, every job. Scott brings 20 years of hands-on experience to your attic, your crawl space, your mechanical room — not 20 years managing a brand, but 20 years diagnosing and cleaning the exact flex-duct, sheet-metal, and hybrid systems found in Houston homes.
Our response time to Houston neighborhoods averages under an hour for standard bookings and same-day for urgent situations — post-flood calls, chemical odor complaints from east Houston, or systems blowing visible debris. We know which ZIP codes flood first, which attics hit 140°F by 10 a.m. in July, and which post-Harvey rebuilds used substandard flex duct that needs full replacement rather than cleaning. That local knowledge saves Houston customers from paying for a service that won’t solve their actual problem.
Our equipment roster reflects the severity of Houston conditions: Rotobrush rotary brush systems for mechanical agitation of microbial buildup, Nikro HEPA vacuums for containing hazardous particulates, and Abatement Technologies sanitizing systems for the mold and bacteria colonization that’s standard here, not exceptional. We don’t rent equipment between jobs — we own it, maintain it, and match it to the specific contamination pattern we find in your system.
Our Air Duct Cleaning Services in Houston
Residential Duct Cleaning
Houston’s single-family homes present two distinct challenges depending on era and location. The 1970s–1990s suburban explosion built thousands of homes with flex duct through unconditioned attics — we’ve cleaned systems in Katy, Sugar Land, and Clear Lake where the foil facing had degraded so severely that the duct was essentially open to the attic. In older neighborhoods like Montrose, the Heights, and Garden Oaks, we encounter galvanized sheet-metal trunk lines from pre-1950s construction or non-standard retrofits from window-unit conversions. Our residential cleaning scopes differently for each: rotary brush and HEPA vacuum for standard flex systems, modified agitation tools and hand-cleaning for vintage metalwork, and always video inspection to verify we reached the full network.
Commercial Duct Cleaning
Houston’s commercial buildings — medical offices near the Texas Medical Center, retail along Westheimer, warehouses near the Port — face amplified contamination loads from longer operating hours and larger occupant counts. We clean commercial systems after hours to minimize disruption, using Nikro portable HEPA systems that contain debris without shutting down your HVAC. For restaurants and food-service operations in areas like Chinatown or the East End, grease and moisture combine in return ducts to create thick, hazardous buildup that requires specialized degreasing pretreatment before mechanical cleaning. Scott Gray scopes every commercial job personally — no sending an inexperienced crew to figure out your rooftop package unit or VAV box configuration.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms, but in Houston they also deliver whatever’s growing upstream. The first several feet of supply plenum sit directly downstream of your evaporator coil, which stays wet six to nine months a year here. That chronic moisture breeds mold and bacteria that colonize the supply trunk and branch lines, blowing spores into every room every time the AC cycles. We clean supply ducts with rotary brush agitation followed by HEPA vacuum extraction, then apply Abatement Technologies sanitizer to the full supply network — a step that’s standard in our Houston protocol, not an upsell. Homes in flood-prone areas like Meyerland or near Brays Bayou often need supply duct replacement rather than cleaning if standing water sat in the lines.
Return Duct Cleaning
Return ducts pull air from your living space back to the air handler, making them the primary collection point for household dust, pet dander, and — in Houston’s unique environment — the humid, particle-laden air that enters through leaks in your building envelope. We see return ducts in Houston homes pulling attic air through disconnected flex connections, introducing fiberglass particles and 140°F heat into the system. Our return duct cleaning includes sealing accessible leaks with mastic and foil tape, not just debris removal. In east Houston neighborhoods downwind of the Ship Channel — Galena Park, Pasadena, Channelview — return ducts accumulate a dark, oily industrial particulate that standard cleaning won’t fully remove; we use extended HEPA vacuuming cycles and, where contamination is severe, recommend duct replacement with sealed, hard-piped returns.
Full System Cleaning
Most Houston homes need full system cleaning, not isolated supply or return service. The humidity and contamination here create feedback loops: mold in the return spreads to the coil, colonizes the supply, and recirculates. Our full system scope includes all supply and return ductwork, the air handler cabinet, the evaporator coil (when accessible), and the blower assembly. We finish with video inspection documentation so you see what we removed and what condition your system is in now. For post-flood homes, full system cleaning often reveals that standard cleaning is insufficient — Hurricane Harvey left silt and mold in inaccessible flex runs that we only discover with camera inspection, and we’ve advised many Houston homeowners that partial replacement is the only real solution.
Video Inspection
We video inspect before quoting and after cleaning on every Houston job. The pre-cleaning inspection identifies disconnected ducts, standing water, flood residue, and corrosion damage that changes our scope and your cost. The post-cleaning inspection proves the work — you’ll see the before and after on screen. In older Houston homes with non-standard layouts, video inspection is essential for finding ducts that were buried in walls during renovations or converted from original gravity systems. We’ve found completely blocked lines in Heights bungalows and illegal flex-to-flex connections in 1980s Memorial subdivisions that the homeowner never knew existed.

Trusted Brands We Service in Houston
We clean and service duct systems connected to all major HVAC brands, and we stock Honeywell and Aprilaire media filters and air quality accessories for Houston customers who want to upgrade filtration after cleaning. Our Rotobrush, Nikro, and Abatement Technologies equipment is matched to the contamination we find — no single tool handles every Houston duct problem. For air sanitizing, we use Guardsman-treated protocols in homes with persistent microbial issues, particularly in flood-impacted areas where standard cleaning leaves residual contamination. Parts and filters for Houston customers are typically available same-day; we don’t make you wait for a second appointment to complete the job.
Common Air Duct Cleaning Problems We See in Houston Homes
- Post-flood mold and silt contamination. Hurricane Harvey inundated roughly 154,000 structures in Harris County, and subsequent tropical storms have added to the total. Floodwater enters duct systems through return grilles, disconnected attic connections, and even small leaks, depositing silt in low points and mold throughout. Standard cleaning protocols from drier markets miss this entirely — we’ve opened flex ducts in Houston homes that looked clean externally but contained packed mud and active mold colonies inside.
- Attic heat degradation of flex duct. Houston’s unconditioned attics exceed 140°F for months each summer, baking the foil facing and mastic on flex duct connections until they crack and separate. Once gaps open, the system pulls in fiberglass insulation particles, humid attic air, and rodent debris. We find this in virtually every 1980s–1990s suburban home we inspect — it’s not a question of if, but how severe.
- Petrochemical particulate in east Houston. Homes in Galena Park, Pasadena, Channelview, and Deer Park sit downwind of the Ship Channel’s dense refinery complex. The dark, oily residue our technicians pull from filters and duct interiors in these ZIP codes is chemically distinct from household dust — it causes persistent vent odors even when ducts appear visually clean, and it requires specialized HEPA vacuuming and sealing protocols standard equipment won’t address.
- Chronically wet evaporator coils and plenums. Houston’s 75–80% average humidity keeps coils and the first feet of return plenums wet through the long cooling season. This near-ideal environment for mold and bacteria means sanitizing treatments aren’t optional here — they’re necessary to prevent immediate recontamination after cleaning. We apply Abatement Technologies sanitizer as standard protocol on every Houston job.

FAQs — Air Duct Cleaning in Houston
Schedule duct inspection within 48–72 hours of water receding, but do not run your HVAC until a technician confirms the system is dry and uncontaminated. Running a flooded system drives mold spores and silt through every room and can destroy your blower motor and evaporator coil. We’ve responded to post-flood calls throughout Houston — from Harvey in 2017 to Tropical Storm Imelda in 2019 and beyond — and the homes that fared best were the ones that kept the system off until we could video inspect and either clean or recommend replacement. Call (855) 683-5929 for emergency flood assessment; we prioritize these calls same-day.
The odor comes from petrochemical particulate deposited by refinery emissions that enter your home’s ventilation intake and accumulate in duct interiors — standard dust removal won’t eliminate it because the residue bonds to duct surfaces and continues off-gassing. We encounter this regularly in Galena Park, Pasadena, Channelview, and Deer Park. Our protocol adds extended HEPA vacuuming cycles with Nikro equipment and, for severe cases, duct sealing or replacement with hard-piped returns that don’t absorb the residue. Video inspection confirms whether cleaning will suffice or if replacement is the only permanent solution. Call (855) 683-5929 — we’ll identify the source and give you a straight answer on what it’ll take to stop the smell.
Yes — fundamentally different. Montrose bungalows and Heights cottages often have pre-1950s galvanized sheet-metal trunk lines, non-standard branch configurations from window-unit conversions, or ducts buried in walls during decades of renovation. These require hand-cleaning, modified brush tools, and careful video navigation to avoid damaging fragile connections. Newer suburban homes in Katy, Sugar Land, or Pearland typically have uniform flex-duct systems that respond well to rotary brush cleaning — but they’re also the ones most likely to have attic heat damage and disconnected runs. Scott Gray scopes both types personally and adjusts the approach before we start. Call (855) 683-5929 and tell us your neighborhood — we’ll know what we’re walking into.
Peeling foil facing usually indicates the flex duct insulation and vapor barrier have degraded from attic heat exposure — common in Houston’s 140°F summer attics. We can clean through damaged sections if the inner liner is intact, but we typically recommend replacing degraded flex runs rather than cleaning them, since the exposed insulation will continue shedding particles into your air stream. During our video inspection, we’ll show you exactly where the damage is and whether spot repair, section replacement, or full replacement makes sense. We handle duct repair and sealing in-house — no calling a second contractor. Call (855) 683-5929 for inspection and we’ll give you both cleaning and repair options with fixed pricing.
In Houston’s climate, visible mold in ducts is common enough that we treat sanitizing as standard, not as a separate “remediation” service. Our full system cleaning includes Abatement Technologies sanitizer application to all accessible duct surfaces, the air handler, and the coil area — this handles the microbial growth we find in nearly every Houston system. True mold remediation (containment, negative air, removal of porous materials) is only needed when floodwater sat in the ducts or when mold has penetrated drywall and framing around the plenum. We’ll tell you honestly which situation you’re in after video inspection. Call (855) 683-5929 for a free scope — we’ll show you what we’re seeing and recommend the right level of service.
