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 Friendswood
Air duct cleaning in Friendswood typically runs $380-$720 for a full residential system and $180-$340 for supply or return-only service, with most jobs completed in a single visit. We dispatch crews to Friendswood from our Houston office and carry equipment for both standard cleaning and the post-flood verification work this market demands. If your home was built between the late 1960s and 1990s, or if it sits anywhere near the Clear Creek corridor, the condition of your ductwork is likely more complex than a routine maintenance visit can address. Call (346) 253-1822 for a written estimate before any work begins.

Our Air Duct Cleaning Services in Friendswood
Residential Duct Cleaning
Friendswood’s housing stock is dominated by slab-on-grade ranches and split-levels built from the late 1960s through the 1990s, with attic-run flex duct systems now 30-50 years old. Those original ducts weren’t designed for decades of Houston humidity, and many have never been opened since installation. Our residential cleaning includes full-system agitation under negative pressure with HEPA filtration, plus a video inspection to document what we find. We photograph every run before and after, and we flag degraded liner, biological growth, or flood residue for your review.
Commercial Duct Cleaning
Friendswood’s commercial base includes medical offices along FM 518, retail at Baybrook Mall’s periphery, and professional services near the intersection of Bay Area Boulevard and NASA Road 1. These facilities operate under tighter occupancy and liability standards than residential work, and their duct systems often combine original construction with multiple tenant modifications. We quote commercial jobs with the same written-upfront protocol, scaled to building size and system complexity, with photo documentation delivered as a standard job record.
Supply Duct Cleaning
The supply side pushes conditioned air into your living spaces, and in Friendswood homes it’s where we most often find the visible evidence of trouble: dark lines at register openings, degraded flex liner shedding particles, or the dried silt rings that indicate prior flood contact. Supply duct cleaning targets these runs specifically, using Rotobrush agitation and negative-pressure extraction to remove buildup without damaging aging materials. We recommend this as a standalone service only when the return side tests clean and the video inspection confirms intact duct structure.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Friendswood’s older homes they’re often oversized, poorly sealed, or routed through wall cavities that act as unintended plenums (distribution chambers that collect dust and debris). A return-side cleaning addresses the intake path, but it’s also our opportunity to test for duct leakage and pressure imbalance. If we find significant leakage - common in post-Harvey renovations where wall assemblies were disturbed - we’ll document it and quote sealing work under the same written-price protocol.
Video Inspection
This is where our Friendswood work diverges from routine maintenance. We run a camera through every accessible duct run, and in this market we find specific, local failure modes: crushed flex behind air handlers, disconnected joints feeding entire rooms, and silt lines that trace floodwater paths through the system. The video becomes part of your documented photo record, timestamped and delivered with the job summary. You see what we see, before any cleaning or repair work is authorized.
Full System Cleaning
Most Friendswood homes need this. Full system cleaning covers supply and return ducts, the plenum (the main distribution box attached to your air handler), and accessible register boots. We use professional-grade equipment from Abatement Technologies and Guardsman, with HEPA-filtered negative pressure to contain debris. The job concludes with before-and-after photography of every run, a written scope of work performed, and the 365-Day Done Right Promise.

BeforeAfterTrusted Brands We Service in Friendswood
Our equipment roster includes Rotobrush agitation systems, Nikro and Abatement Technologies negative-pressure extractors, and air quality components from Honeywell, Aprilaire, and Guardsman. These are trade-recognized brands, not proprietary equipment, and customers can verify specifications independently. We stock common fittings and replacement materials for Friendswood’s predominant duct types, which keeps turnaround short when a cleaning reveals a repair need. If your system uses Aprilaire media filters or Honeywell electronic air cleaners, we service and replace those components as part of the job scope.
Common Air Duct Cleaning Problems We See in Friendswood Homes
- Original flex duct with degraded inner liner. The 30-50 year old attic flex in Friendswood’s core subdivisions has a porous inner liner that holds biological growth through our year-round humidity. Even homes with no flood history show mold colonization at supply registers and inside duct boots. The system still moves air, so homeowners don’t know the liner is shedding particles into occupied spaces.
- Post-Harvey flood contact left in place. Many homes along the Clear Creek corridor were gutted and rebuilt after 2017, but the flex duct runs in the attic were often left in place. Dried silt lines inside duct boots at the registers are frequently the only surviving evidence that the system was ever flooded. Homeowners who bought after renovation typically have no documentation of what was or wasn’t replaced.
- Crushed, kinked, or disconnected runs found only on camera. The system still “works” - air is moving, rooms are cooling - but a video inspection often reveals that half the house is being fed from a disconnected joint dumping conditioned air into the attic. We find this regularly in the 1970s-1980s ranches off FM 518 and in the Bay Area Boulevard corridors where original installation quality was inconsistent.
- Humidity-driven mold at registers and plenum connections. Friendswood’s proximity to Galveston Bay keeps indoor relative humidity elevated even when thermostats are set low. Mold colonizes at the supply register face and at the plenum connection to the air handler, visible as dark staining that returns after surface cleaning. Duct cleaning addresses the source; register replacement or plenum sealing may be needed to stop recurrence.
Pricing for Air Duct Cleaning in Friendswood, TX
A typical full system cleaning in Friendswood runs $380-$720 for a single-system residential home, depending on duct count, accessibility, and whether video inspection reveals repair needs. Supply-only or return-only service ranges from $180-$340. Commercial jobs start around $850 and scale with system complexity.
What moves the price: number of duct runs, condition of original materials (degraded liner requires gentler, slower agitation), accessibility in attic spaces with limited clearance, and whether we find disconnected or flood-damaged sections that need repair or replacement. We do not price per vent. Haven Standard Clause 1 requires one flat price per system, agreed in writing before work starts. No exceptions.
Every estimate is free. We deliver a written scope and price on site before any panel comes off, and we include the documented photo record as a standard deliverable, not an add-on. Call (346) 253-1822 to schedule.

FAQs - Air Duct Cleaning in Friendswood
The most reliable indicator is a dried silt line inside the duct boot at the supply register, visible when the register is removed. In a 1978 slab-on-grade ranch off FM 518 near the Clear Creek corridor, our tech pulled a supply register and found exactly that - the duct had taken on Harvey water and been left in place through the renovation. Camera inspection showed a crushed run behind the air handler and a disconnected flex joint feeding two bedrooms, so we cut out the failed sections, ran agitation tools through the remaining supply and return ducts under negative pressure with HEPA filtration, and sealed the joints that were dumping conditioned air into the attic. If your home changed hands after 2017 and you have no renovation documentation, a video inspection will show what remains in the system. Call (346) 253-1822 for a free estimate.
Friendswood’s sustained humidity - among the highest in the Houston metro due to proximity to Galveston Bay - keeps indoor relative humidity elevated and promotes mold colonization inside duct liners even in homes with no flood history. The musty smell is typically volatile organic compounds from active biological growth at the supply register face or inside the plenum. A video inspection locates the colonization, and full system cleaning with HEPA-filtered negative pressure removes the source. If the inner liner is degraded, we document it and quote replacement. Call (346) 253-1822 for a written scope and price.
In Friendswood’s 30-50 year old homes, duct cleaning fixes three interconnected problems: accumulated debris and biological growth in the original flex duct, disconnected or crushed runs that compromise airflow and efficiency, and flood residue from 2017 that was never removed. The cleaning itself addresses the first; the video inspection typically reveals the second and third, which we quote for repair under the same written-price protocol. The documented photo record shows you exactly what was found and what was done. Call (346) 253-1822 to schedule.
Yes. Slab-on-grade construction routes ducts through the attic, not the slab, so access is from above via attic entry. We remove register faces from below and run agitation tools and cameras from the attic side. No drywall demolition is required for standard cleaning or video inspection. If we find a crushed run behind the air handler or in a wall cavity, we document the location and quote repair with minimal intrusion. Call (346) 253-1822 for a free estimate.
Yes. Thermostat setting controls air temperature, not humidity removal. Friendswood’s outdoor humidity - consistently high due to Galveston Bay influence - infiltrates through building envelope leaks and is introduced by normal occupancy. When indoor relative humidity stays above 60 percent, mold colonizes duct liners and register boots regardless of thermostat setpoint. The only effective control is dehumidification integrated with the HVAC system, combined with duct sealing to reduce unconditioned air infiltration. We assess this during our video inspection and quote sealing work when indicated. Call (346) 253-1822 for a written evaluation.
