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.
Fast, Reliable Air Duct Cleaning Across Highlands
Most homeowners in Highlands pay between $320 and $580 for a complete residential air duct cleaning, with full-system jobs that include supply and return runs, main trunk lines, and a video inspection typically landing in the middle of that range. We’re local to the area, dispatching crews from our Houston office to Highlands homes with the equipment already loaded: Rotobrush rotary systems, Nikro negative-pressure extractors, and Abatement Technologies HEPA filtration. Call (469) 972-3151 and you’ll reach a live person, not a voicemail tree, any time of day. We’ll give you a written price before a single vent is touched.
Highlands isn’t like the suburbs further inland. The homes here, mostly built from the 1950s through the 1970s for Ship Channel workers, carry ductwork that has seen decades of industrial particulate loading, repeated flooding from the San Jacinto River, and the slow crush of flex duct in unconditioned attics. Our Air Duct Cleaning team knows what to look for in these houses because we’ve opened enough of them to recognize the patterns: the Harvey sediment line inside a low crawl-space return, the flattened 6-inch flex run buried under attic insulation, the sulfur-compound residue that wipes off black on a white cloth. That local knowledge changes what we find and how we fix it.
Why Kestrel Air Duct Cleaning Is Highlands’s Preferred Air Duct Cleaning Company
We’ve been operating under the Kingswell Guarantee since 2004, and that same written standard applies to every Highlands job we run. The four promises never change: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. No exceptions.
Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment, not box-store shop vacs. The Rotobrush dislodges debris at the duct wall with a rotating cable brush. The Nikro unit pulls that debris out under negative pressure. The Abatement Technologies HEPA system keeps loosened particles out of your living space while the work is happening. We explain each step as we go because The Kingswell Way says you should know exactly what you’re paying for.
Calls are answered by a live person 24/7. Not an automated system. Not a callback queue. A real conversation, whether you’re calling at 7 a.m. before work or 9 p.m. after noticing a smell from the registers. For Air Duct Cleaning in Highlands, that accessibility matters because duct problems here often show up as urgent: a post-Harvey mold bloom after heavy rain, or a crushed supply run that suddenly stops delivering air to a bedroom.
The 365-Day Done Right Promise covers every job in writing. If the work falls short within that year, we return and make it right at no charge. Not as a favor. As a documented obligation.
Air Duct Repair in Highlands
Air Duct Repair in Highlands often starts with a cleaning visit that reveals damage the homeowner couldn’t see from the register. In these 1950s-70s homes, we regularly find flex duct runs that have been flattened by decades of attic insulation, rodent traffic, or the original installer simply failing to support the run properly across a long span. The register still blows air, so the homeowner assumes the system works. But the blower motor is working harder, the amps are higher than spec, and the room never quite reaches temperature. Repair means cutting out the damaged section, properly supporting the new run with strapping at code spacing, and re-sealing the plenum collar with mastic, not tape that will dry and fail in the attic heat.
A typical air duct repair in Highlands runs $180-$420 depending on how much material needs replacement and whether the damage is accessible from the attic or requires crawl-space work. We put that number in writing before we cut anything.
Crushed Flex Duct Replacement
Off Wallisville Road and along Crosby-Lynchburg, we find 6-inch flex duct from original 1960s and 1970s installs that has collapsed to half its diameter under blown-in insulation. The fix is surgical: remove the crushed section, inspect the plenum connection for cracks, and install new supported flex with a proper metal collar and sealed joints. A shop vac won’t find this. A video inspection will.
Post-Flood Return Duct Remediation
Harvey’s floodwaters reached into low crawl-space returns on pier-and-beam homes throughout Highlands. Even if the living space was remediated in 2017, the duct interior often was not. We open these returns, HEPA-vacuum under negative pressure, and apply antimicrobial before re-sealing. The sediment line on the duct wall tells us exactly how high the water stood.
Ductwork Cleaning in Highlands
Ductwork Cleaning in Highlands means more than pushing a brush down a metal tube. The ductwork here carries a specific load: industrial particulates from the Ship Channel petrochemical corridor, sulfur compounds that bind to damp duct walls, and in many older homes, the residual contamination from 2017 floodwater intrusion. Our process starts with a video inspection so you see what we see. Then we use rotary brush agitation, the spinning cable brush that physically knocks debris loose from the duct interior, followed immediately by negative-air extraction, the vacuum pull that carries that debris out of your system and into a filtered collection unit rather than redistributing it through your house.
A full ductwork cleaning for a typical Highlands home runs $320-$580. Larger homes with multiple zones, or homes requiring post-flood remediation of low returns, can run higher. We price by the complete system, not by the vent, so the written quote you hold is the number you pay.
Supply and Return Run Cleaning
Supply ducts push conditioned air to your rooms. Return ducts pull air back to the handler. Both sides need cleaning, but the returns typically hold more debris because they’re the intake path. In Highlands, returns near the floor or in crawl spaces often show the heaviest loading, industrial particulate and all.
Main Trunk Line and Plenum Service
The trunk line is the large central duct that feeds the smaller runs. The plenum is the box directly attached to your air handler. These components move the most air volume and collect the most debris, yet many cleaners skip them. We don’t. Opening and cleaning the plenum also lets us inspect the evaporator coil and blower assembly for contamination that would immediately re-soil clean ducts.
Trusted Brands We Service in Highlands
We clean ductwork connected to every major HVAC brand, and we stock Honeywell and Aprilaire filtration products for Highlands homeowners who want to maintain cleaner air between service visits. The Honeywell F100 and F200 media air cleaners install in the return plenum and capture particles down to 0.3 microns, which matters here given the fine industrial particulate in the local air. Aprilaire’s 2210 and 2410 models use a similar pleated media approach with a pressure-drop design that doesn’t strain older blower motors. For homes with specific odor concerns, Guardsman carbon-pleated filters are available. We carry these in our Houston inventory, so Highlands customers don’t wait for shipping. If your system needs a filtration upgrade after cleaning, we can quote and install same-visit.
Common Air Duct Cleaning Problems We See in Highlands Homes
- Industrial particulate binding to damp duct walls. The Ship Channel puts sulfur compounds and VOCs into the ambient air that Highlands homes breathe. Those compounds adhere to the moisture film inside ducts and create a nutrient-rich surface for mold colonization that a surface wipe won’t touch.
- Harvey sediment lines in low returns. We still find hardened sediment inside crawl-space returns on pier-and-beam homes, the physical watermark showing how high 2017 floodwater stood. Homeowners were told the house was remediated, but the duct interior was never opened.
- Crushed flex duct in unconditioned attics. The modest single-family homes off Wallisville Road and Crosby-Lynchburg often have original or early-replacement flex duct that has flattened under insulation weight and attic heat, delivering a fraction of design airflow.
- Disconnected plenum collars and supply boots. Decades of thermal cycling in Highlands’s extreme humidity cause mastic sealant to crack and metal collars to pull apart. Conditioned air leaks into the attic before it ever reaches the room.
Pricing for Air Duct Cleaning in Highlands, TX
Here’s what honest pricing looks like for this market. A typical residential duct cleaning in Highlands runs $320-$580 for a complete system: supply runs, return runs, main trunk, and plenum, with video inspection before and after. Commercial systems start around $680 and scale with square footage and access complexity. Post-flood remediation of low returns, or repair of crushed flex duct, adds $180-$420 depending on material and labor.
What moves the number? System size matters. So does access, attic versus crawl space. The condition of the ductwork matters, heavily loaded systems take longer.

FAQs About Air Duct Cleaning in Highlands
Yes, if your home has low returns in a crawl space or pier-and-beam foundation, the duct interior was likely submerged and may not have been opened during 2017 remediation. We still find sediment watermarks inside these returns. Call (469) 972-3151 for a video inspection that will show you exactly what’s in there.
Highlands homes draw in air with elevated industrial particulate, sulfur compounds, and VOCs that inland suburbs don’t experience at the same concentration. These compounds adhere to damp duct walls and accelerate mold colonization. Cleaning intervals here are often shorter than the national average. Call (469) 972-3151 and we’ll assess your specific loading.
We start with a video inspection, feeding a camera through the ductwork to show you the interior condition in real time. Crushed flex duct, disconnected collars, and sediment lines are all visible. We also measure static pressure and blower amp draw, which rise when the system is working against restricted airflow. Call (469) 972-3151 to schedule.
We use rotary brush agitation, a spinning cable brush that physically knocks debris loose from duct walls, followed by negative-air extraction, a vacuum pull that carries debris into a filtered collection unit outside your living space. Without negative pressure, loosened debris would simply recirculate through your home during cleaning. Call (469) 972-3151 for a free estimate.
The dryer vent, the evaporator coil, and the blower assembly. In Highlands’s humid climate, dryer vents clog faster with lint and moisture, creating fire risk. The coil and blower, if contaminated, will immediately re-soil clean ducts. We inspect all three during a full-system visit. Call (469) 972-3151 to book.
We pulled a 1970s flex run out of a pier-and-beam home off Wallisville Road that was still on its original 6-inch duct and found it flattened under attic insulation, rechargeable only by tearing out the crushed section and re-sealing the plenum collar. The low crawl-space return had a visible sediment line about 14 inches up the duct wall - the Harvey watermark - so we treated that entire run as contaminated, HEPA-vacuumed it under negative pressure, and applied antimicrobial before reconnecting the supply and return ducts. When our tech finished, the blower motor was pulling noticeably fewer amps and the customer said the house no longer smelled like the refinery on humid mornings.
