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 Four Corners
Air duct cleaning in Four Corners, TX typically costs $320-$580 for a full residential system and includes a documented photo record of every duct run before and after work. Most Four Corners homes need service every 3-5 years, though newer construction and post-Harvey moisture exposure often shorten that interval. Call (346) 666-7165 for a written estimate before any work begins.
We serve Four Corners from our Houston coordination office, with crews running daily routes through Fort Bend County. If you live off FM 1093 or in the neighborhoods near the Grand Parkway corridor, you’re on a route we already know. The tract-home density here means we’ve cleaned ducts in floor plans identical to yours, and we know where the builder shortcuts typically show up.
Four Corners grew fast during Fort Bend County’s 2000s-2010s boom, and that speed left a mark inside the ductwork. We’re the local Air Duct Cleaning team that documents what we find instead of asking you to trust a verbal report.
Why CleanRun Air Duct Cleaning Katy Is Four Corners’s Preferred Air Duct Cleaning Company
We’ve been serving the Houston metro since 2013, and Four Corners has been a core part of our route network for years. The 52,000+ homes in our job history include hundreds in Fort Bend County’s newer subdivisions, many with the same builder-grade flex duct systems that dominate this market.
Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Every job starts with a written price delivered before a single panel comes off, and ends with a Documented Photo Record showing the interior of every duct run, before and after. The 365-Day Done Right Promise applies in writing, not as a verbal assurance.
Scheduling is coordinated from our Houston office, but the crew that arrives at your Four Corners door knows the area. They know which builders used which flex-duct suppliers, which attic configurations trap condensation, and which post-Harvey remediation patterns missed the ductwork entirely. That local pattern recognition means faster diagnosis and no exploratory billing.
Our Air Duct Cleaning Services in Four Corners

Residential Duct Cleaning
Four Corners homes are almost exclusively slab-on-grade construction with attic-routed flex duct, a configuration that puts the entire system through extreme thermal cycling. Summer attic temperatures exceed 140°F while the AC pushes 55°F air through the same flex runs, creating condensation that binds drywall dust and biological debris to the duct lining. Our residential service uses negative-pressure extraction with HEPA filtration, agitating the interior surface with Rotobrush or Nikro tools to dislodge material that vacuum suction alone won’t move. Every supply and return run is photographed before and after.

Commercial Duct Cleaning
Four Corners’s commercial base includes retail along FM 1093, medical offices, and property-management portfolios for the rental stock that serves the energy corridor commute. Commercial systems in this market typically use rigid metal trunk lines with flex duct drops, and the cleaning protocol differs accordingly. We size the negative-pressure equipment to the plenum volume, document fire-damper integrity during the process, and deliver a written scope completion record for property managers who need evidence for owners or insurers. Our crews hold the documented credentials required for commercial access in Fort Bend County.

Supply Duct Cleaning
Supply ducts carry conditioned air to your registers, and in Four Corners they’re the runs most likely to show construction debris at the joints. Builder crews often leave flex-duct shavings and drywall dust inside the supply trunk during rough-in, and the positive pressure from the air handler can pack that material against the first elbow or register boot. We isolate each supply run, establish negative pressure at the register, and work back toward the plenum with mechanical agitation. The camera doesn’t lie: you’ll see the obstruction in the before photo and the clear interior in the after.

Return Duct Cleaning
Return ducts pull air from your rooms back to the air handler, and in Four Corners they’re the primary collection point for the particulate load this region generates. Pollen counts in Fort Bend County run high for eight months of the year, and the 8-9 month AC cycle here means that load never gets a seasonal break. Return duct cleaning is where we most often find the post-Harvey moisture damage in lower-lying Four Corners homes: discolored flex-duct lining, musty odor at the grille, and reduced airflow that the homeowner has been compensating for by lowering the thermostat. We document the condition, clean the run, and note any structural damage that requires repair before the system is sealed back up.

Full System Cleaning
A full system cleaning in Four Corners addresses every component: supply trunk and branches, return trunk and branches, the plenum (the distribution box at the air handler), and the register boots where duct meets wall or ceiling. This is the service we recommend for any home that hasn’t had documented duct cleaning since construction, and for any post-Harvey property where moisture exposure is part of the history. The written scope specifies every component included, and the photo record covers every accessible interior surface.

Video Inspection
Our video inspection service uses a push camera through the duct interior to locate blockages, moisture damage, or structural failure in flex-duct systems. In Four Corners, this is particularly valuable for the 10-20 year old builder-grade flex duct that’s now reaching its failure window. The camera shows sagging at joints, separation at connection collars, and biological growth on the interior lining - conditions that explain musty odors or weak airflow without guessing. The inspection record becomes part of your job file, and if cleaning alone won’t solve the problem, you’ll have the documentation to make an informed repair decision.

Common Air Duct Cleaning Problems We See in Four Corners Homes

- Construction debris left from new-home handover. Four Corners homes built during the 2000s-2010s boom were often occupied before the ductwork was properly cleaned. Drywall dust, sawdust, and flex-duct cuttings remain packed at joints and elbows, restricting airflow from day one. Homeowners assume a new house has clean ducts; the camera usually proves otherwise.
- Post-Harvey moisture damage never addressed at the duct level. Surface remediation after 2017 focused on drywall, flooring, and visible finishes. The attic-routed flex duct in many lower-lying Four Corners homes was never opened, dried, or inspected. Years later, we find active mold colonies cycling into living spaces through registers that tested “clean” at the surface.
- Flex-duct sag and separation at 10-20 years. Builder-grade flex duct loses structural integrity faster in Houston’s climate. The wire helix corrodes, the insulation compresses, and the interior lining traps debris in the low spots. Standard HVAC maintenance never opens the duct to check; we do, and we photograph what we find.
- Condensation cycling from extreme attic temperatures. When 140°F attic air surrounds a duct carrying 55°F conditioned air, moisture forms on the exterior and wicks into any breach in the vapor barrier. Four Corners’s slab-on-grade construction puts nearly the entire duct system in this environment. The result is accelerated biological growth and insulation degradation that reduces system efficiency.
Pricing for Air Duct Cleaning in Four Corners, TX
A typical full residential system cleaning in Four Corners runs $320-$580, depending on the number of duct runs, the accessibility of the attic plenum, and the material load inside the ducts. Supply-only or return-only cleaning ranges from $180-$340. Video inspection as a standalone service is $145-$225; when bundled with cleaning, it’s reduced. Commercial system pricing is scoped per square foot and plenum complexity, with written estimates delivered on-site.

What moves a job toward the higher end: excessive construction debris requiring extended agitation time, post-Harvey moisture damage requiring antimicrobial treatment, or hard-to-access attic configurations that extend crew time. What we don’t do: quote a low opening price and add per-vent charges once the truck is on your driveway. Haven Standard Clause 1 requires one flat price per system, agreed in writing, before work starts. No exceptions.

FAQs - Air Duct Cleaning in Four Corners

Because construction debris is standard, not exceptional, in new Fort Bend County tract homes. Drywall dust, sawdust, and flex-duct cuttings are left inside the runs during rough-in, and builders rarely perform source-removal cleaning before handover. In Four Corners, where the 2000s-2010s build pace was particularly intense, we’ve found packed debris at the first elbow in homes still under builder warranty. The camera shows it; the photo record proves it. Call (346) 666-7165 for an exact quote - estimates are free.
Yes. Surface remediation after 2017 often stopped at visible finishes, leaving attic-routed flex duct untouched. We regularly find active mold colonies inside ductwork that was “remediated” at the room level but never opened, dried, or inspected at the duct interior. Our protocol for post-Harvey Four Corners homes includes moisture assessment with the video inspection, antimicrobial treatment where indicated, and full documentation of the duct condition before any cleaning commitment. Call (346) 666-7165 for an exact quote - estimates are free.
Video inspection is the only method that distinguishes structural failure from surface debris. Sagging at joints, separation at connection collars, and corrosion of the wire helix show up on camera as distinct from debris accumulation. In Four Corners’s 10-20 year old builder-grade flex duct, we see both conditions together more often than either alone. The photo record from our inspection lets you see the difference and make an informed repair-or-clean decision. Call (346) 666-7165 for an exact quote - estimates are free.
Yes, measurably. Outdoor relative humidity in the Houston metro frequently exceeds 75%, and attic temperatures in Four Corners exceed 140°F in summer. When 55°F conditioned air moves through flex duct in that environment, condensation forms on any breach in the vapor barrier and wicks into the insulation and interior lining. The result is accelerated mold colonization, insulation compression, and structural degradation that doesn’t occur in drier or cooler climates. AC systems here run 8-9 months a year, so the moisture cycle never gets a seasonal break. Call (346) 666-7165 for an exact quote - estimates are free.
Ask for written proof of four things: a price delivered before work starts, background-checked and identified technicians, a photo record of every duct run before and after, and a written warranty backed by a named standard. CleanRun operates under the H.A.V.E.N. Standard, with Haven Standard Clause 1 (written upfront pricing), Clause 3 (verified crews), and the 365-Day Done Right Promise applied to every Four Corners job. If a competitor won’t put these in writing, that tells you what their verbal promises are worth. Call (346) 666-7165 for an exact quote - estimates are free.
