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 South Houston
Air duct cleaning in South Houston typically runs $350-$650 for a whole-home residential system, with most jobs completed in a single visit. We dispatch crews from our Houston office to South Houston daily, and we’ll give you a written price before any work starts.
We’ve been working in South Houston since 2005, and we know the homes here. The modest ranch and bungalow stock built between the late 1940s and early 1970s for industrial workers along the Ship Channel, the original flex duct that’s now brittle from decades of humidity cycling, the attics that hit 140°F in July. We also know the dark, oily film on supply registers that isn’t ordinary dust. It’s a petrochemical-tinged residue from the refinery corridor less than three miles north, and it takes real equipment to remove. Our Air Duct Cleaning team uses Rotobrush and Nikro systems with negative-pressure HEPA containment to pull that contamination out of your ductwork, not just move it around. Call (323) 918-4345 for a free estimate.
Why Morton’s Air Duct Cleaning Is South Houston’s Preferred Air Duct Cleaning Company
South Houston families call us back because we treat their homes the way we’d want our own treated. Shoe covers and drop cloths before we step inside. Quiet tool settings when there’s a toddler napping down the hall. Pet-safe product choices where they’re available. Every technician is background-checked and arrives in uniform, working to the Cedarwell C.A.R.E. values that govern how we move through your space.
Our reputation here is built on specifics, not slogans. The 365-Day Done Right Promise is stamped on every job sheet. If something isn’t right, we make it right. Full stop. A live person answers our phone 24/7, and every completed job includes a photo of the clean-up before the crew leaves. You’ll see your registers, your floors, your protected space.
We coordinate dispatch from our Houston office, which means South Houston appointments book quickly without the delays of a company routing from the far suburbs. We know the streets near the industrial corridor, the post-Harvey rebuild zones, the older subdivisions where original ductwork is reaching end of life. That local knowledge changes what we look for during inspection, and it changes what we quote.
Air Duct Repair in South Houston
Air Duct Repair in South Houston addresses the collapsed, separated, and brittle flex duct that dominates local housing stock from the 1950s through 1970s. The combination of original materials, extreme attic heat, and post-Hurricane Harvey moisture intrusion has left many systems with damaged liners, failed seals, and joints that have pulled apart entirely. Repair costs in South Houston typically range from $200-$500 for localized fixes and $800-$1,800 for more extensive re-lining or replacement of multiple duct runs.
Collapsed Flex Duct in Older Homes
We see this constantly in South Houston’s original ranch homes. The wire-reinforced flex duct sags, kinks, or collapses at bends after sixty-plus years of thermal cycling. Our crew inspects with a video camera first, then re-supports or replaces the damaged sections with modern, insulated flex duct rated for our humidity and temperature extremes.
Post-Flood Moisture Damage
Harvey water got into places owners still haven’t found. We open duct runs near slab levels and check for mold colonization on duct liners. Where we find it, we remove the contaminated material rather than cover it up. Source removal is the only approach that solves the problem long-term.
Ductwork Cleaning in South Houston
Ductwork Cleaning in South Houston means dealing with a contamination profile most inland cities never see. The oily, sulfur-compound-laden particulate that settles in your ducts here requires longer agitation cycles and stronger negative-pressure extraction than standard residential jobs. A typical whole-home ductwork cleaning in South Houston runs $350-$650, with larger homes or systems with heavy contamination toward the upper end.
Source Removal vs. Surface Coating
We physically agitate and extract the debris from your duct walls. We do not fog a sanitiser and call it clean. That mist might smell nice for a day, but it leaves the petrochemical residue and mold colonies exactly where they were. Real ductwork cleaning removes the source.
HEPA-Contained Extraction
Our Nikro and Rotobrush equipment runs under negative pressure with HEPA filtration at the air handler. This matters in South Houston because without containment, the sulfur-laden particulate we disturb would simply redistribute through your living space. We capture it, filter it, and remove it from your home entirely.
Trusted Brands We Service in South Houston
We stock parts and service components from Abatement Technologies, Guardsman, Rotobrush, and Nikro. That means when your South Houston home needs a specific fitting, filter housing, or agitation head, we’re not ordering it from a warehouse three states away. We carry the common sizes for the Honeywell, Aprilaire, and other major systems installed in local homes, which keeps turnaround short and your system running while we work. For the industrial-grade contamination we see near the Ship Channel, we rely on Abatement Technologies’ HEPA containment units and Guardsman-rated sealants when resealing duct joints after cleaning or repair.
Common Air Duct Cleaning Problems We See in South Houston Homes
- Dark, greasy register film from petrochemical particulate. That black residue on your supply vents isn’t normal dust. It’s sulfur and hydrocarbon fallout from the refinery corridor, and it requires professional agitation and negative-pressure extraction to remove completely.
- Brittle, collapsed flex duct in unconditioned attics. South Houston’s original 1950s-70s housing stock used early-generation flex duct that degrades faster in our heat and humidity. We regularly find sections that have separated at joints or collapsed entirely, blocking airflow to entire rooms.
- Post-Harvey mold colonization in duct liners. Moisture intrusion from 2017 flooding created ideal conditions for mold growth inside ductwork, especially in homes where owners addressed visible damage but never inspected the HVAC system. We find active colonies with our video inspection equipment.
- Failed seals at air handler connections. The 140°F+ attic temperatures in South Houston summer degrade tape and mastic seals faster than in cooler climates. We reseal with high-temperature-rated materials as part of every cleaning and repair job.
Pricing for Air Duct Cleaning in South Houston, TX
Most whole-home residential duct cleanings in South Houston fall between $350 and $650. A smaller home with straightforward access and light contamination might land near $350. Larger homes, heavy petrochemical residue requiring extended agitation, or systems with significant mold remediation needs can push toward $650 or above. Commercial duct cleaning for South Houston businesses starts around $800 and scales with system size and contamination level.
We quote one flat price per system, agreed in writing before any work starts. No per-vent add-ons. No surprise charges once the van is in your driveway. What we quote is what you pay. The factors that move the number are system size, contamination level, accessibility, and whether we find damage that needs repair. We’ll show you the camera footage and explain what we’re seeing before we adjust anything.
Call (323) 918-4345 for a free estimate. We’ll ask about your home’s age, square footage, and any specific concerns, then give you a range you can plan around.

FAQs About Air Duct Cleaning in South Houston
The dark, oily residue on South Houston supply registers is petrochemical-tinged particulate from the Houston Ship Channel’s refinery and chemical complex less than three miles north. This sulfur and hydrocarbon fallout creates a contamination profile that standard household dusting won’t touch and that requires professional agitation with negative-pressure HEPA extraction to remove. Call (323) 918-4345 if you’re seeing this film, and we’ll inspect your system.
Yes. South Houston’s 70-90% relative humidity for much of the year, combined with 140°F+ attic temperatures in summer, creates near-ideal conditions for mold and mildew growth inside duct runs. Post-Hurricane Harvey moisture intrusion made this worse in many homes where duct systems were never properly inspected after flooding. We find active mold colonies with video inspection, then remove the contaminated material rather than covering it. Call (323) 918-4345 for an inspection.
No. A fogging sanitiser mists the duct surfaces with a chemical that may smell clean temporarily but does not remove the oily petrochemical residue or mold colonies present in many South Houston systems. Without source removal, the contamination remains. We do not upsell fogging services because they do not solve the actual problem. Our cleaning process uses physical agitation and HEPA-contained extraction to remove debris at its source. Call (323) 918-4345 for a quote on real source-removal cleaning.
Expect us to find brittle or collapsed flex duct, degraded seals, and possibly post-Harvey moisture damage in a South Houston home of that era. We’ll run a video camera through the system first to show you exactly what we’re seeing. Many of these homes need some repair alongside cleaning, and we’ll quote both separately so you can decide. The original ductwork served industrial families well for decades, but it’s reaching end of life now. Call (323) 918-4345 and we’ll walk you through what we find.
Ask to see before-and-after photos of your own ducts, not stock images. Verify they’re using negative-pressure HEPA containment, not just a shop vac and compressed air. Confirm they inspect with a camera first, provide a written price before starting, and guarantee the work. At Morton’s, we do all four, and we leave you a photo of the clean-up before we go. The 365-Day Done Right Promise backs every job. Call (323) 918-4345 to schedule with a crew that shows its work.
We pulled a 1968 ranch-style home off a street near South Houston’s industrial corridor where the original flex duct had collapsed at two joints and the supply registers were coated in that telltale black, petrochemical-tinged film. Our tech ran a camera inspection through the supply and return ducts, set up negative pressure with HEPA filtration at the air handler, and used agitation tools plus Rotobrush and Nikro equipment to pull the oily soot off the duct walls before resealing the separated runs. The homeowner noticed the difference in both airflow and odor within a day.
Ready to see what’s actually in your ducts? Call (323) 918-4345 for a free estimate.
