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.

AfterReturn Duct Cleaning in Leander, TX
Return duct cleaning in Leander, TX typically runs between $120 and $280 depending on the number of return vents, duct configuration, and debris load found during inspection. Most jobs are completed in a single visit, and every one starts with a written price before a single panel comes off. If you want to talk through your system before scheduling, call (737) 252-1285 – a live person picks up, not a voicemail.
Return ducts are the half of your HVAC system that most companies skip. Supply Duct Cleaning handles the ducts that push conditioned air into each room; return ducts pull that air back to the air handler to be filtered, conditioned, and recirculated. Because return ducts are under negative pressure – meaning they draw air in rather than push it out – they collect dust, pet dander, insulation fragments, and biological debris at a higher rate than supply runs. In a Leander home with an unchecked return plenum, that debris gets pulled straight across the filter and into the system, bypassing what the filter was designed to catch.
CleanRun Duct Repair & Cleaning has documented this exact pattern in homes throughout Leander since 2013. We’ve served more than 52,000 homes, and our process on every return duct job is the same: camera inspection first, written price second, documented photo record when the crew leaves. Our Air Duct Cleaning in Leander service covers the full system, and return duct cleaning is where that work starts.
When You Need Return Duct Cleaning
Return ducts don’t announce problems loudly. The signs tend to be gradual – things you adapt to rather than notice. Here’s what typically brings Leander homeowners to us:
- Dust resettles within days of cleaning. If surfaces in your living areas are visibly dusty again a few days after you clean them, the return side of your system is likely redistributing what it’s pulling from the ductwork. In older Leander neighborhoods like Crystal Falls and Travisso, where homes may have been sealed up through multiple Central Texas summers, this pattern is common.
- Filter replacement intervals are shortening. A return duct with a heavy debris load upstream of the filter will clog that filter faster than the manufacturer’s rating suggests. If you’re changing filters every three or four weeks instead of every three months, the return system is worth inspecting before replacing the filter again.
- Allergy or asthma symptoms worsen indoors. Central Texas cedar season and oak pollen load the outdoor air hard between November and April. If indoor symptoms track with outdoor pollen counts, uncleaned return ducts may be concentrating what the system draws in.
- A musty or stale odor runs through multiple rooms. Return duct interiors can hold moisture – especially in homes where the air handler sits in a garage or attic, both common configurations in Leander. A camera inspection often shows biological growth at return elbows that a shop-vac approach will never reach.
- Visible debris or discoloration at return grilles. Dark outlines around return grille edges – sometimes called “ghosting” – indicate that the duct behind the grille has enough loose debris to leave a residue on the surrounding wall or ceiling. That’s not cosmetic; it’s the system telling you what’s moving through it.
- Recent renovation or construction in the home. Drywall dust, wood particulate, and insulation fibers from even a small remodel travel straight to the return side. We regularly find construction debris in Leander homes that had work done years prior – it settles in return bends and stays there.
Our Return Duct Cleaning Process
Every return duct job follows the same documented sequence. We don’t adapt the process based on how dirty a duct looks from the outside – we adapt the equipment based on what our Video Inspection shows us on the inside.
- Camera inspection before any work begins. A technician runs a camera through each return duct run and into the return plenum – the main chamber that connects the return air paths to the air handler. You see the footage. We document what’s there: debris depth, type, and location. This is how a written price can be exact rather than estimated with a question mark attached.
- Written price delivered before any panel comes off. Once the inspection is complete, you receive a written price that covers everything the job requires. This is Haven Standard Clause 1, and it applies on every job without exception. There is no “we’ll know more once we get in there” conversation after work has started.
- Negative-pressure extraction setup. Negative-pressure extraction means the system is placed under controlled suction – think of it as sealing the duct and pulling everything toward a collection point rather than pushing debris around. We use Nikro and Rotobrush equipment for this step. The collection point is a HEPA-filtered unit so that what comes out of the duct doesn’t re-enter your home’s air.
- Mechanical agitation of return duct walls. Suction alone doesn’t dislodge compacted debris at bends and elbows. A rotating brush head – Rotobrush equipment is what we run on return duct work – moves through each run to break loose what’s adhered to the duct walls. This is the step that differentiates a real cleaning from vacuum noise applied to a vent cover.
- Return plenum inspection and cleaning. The plenum itself – the main negative-pressure chamber feeding the air handler – is inspected separately. Debris accumulates at the bottom of the plenum in ways that don’t affect individual duct runs but do affect overall system performance. We document and address this as part of the same job, not as an upsell.
- Post-cleaning camera pass and documented photo record. When the work is done, the camera goes back in. Every duct run is photographed after cleaning, and those images are delivered to you as part of the standard job record. You receive before and after documentation for every run – not a summary, not a verbal confirmation. This practice has been part of every CleanRun job since 2013.
BeforeAfterReturn Duct Cleaning Pricing in Leander
Return duct cleaning in Leander costs $120 to $280 for most residential jobs. That range reflects real variation in how systems are built and what’s inside them – not a starting number designed to grow once the technician is in your home.
| Factor | Typical Range |
|---|---|
| Single return duct system (1 return, standard run length) | $120 – $160 |
| Multi-return system (2-4 return vents, standard configuration) | $160 – $220 |
| Heavy debris load or biological contamination requiring additional passes | $220 – $280 |
| Return plenum cleaning (included when combined with full system cleaning) | $0 additional when bundled |
What drives cost in either direction:
- Number of return vents. Leander homes built before 2005 often have a single centralized return. Homes in newer sections – Bryson, Mason Hills, and developments along 183A – frequently have multiple returns on each floor. More returns means more duct footage and more equipment setup time.
- Duct material and configuration. Rigid metal ductwork is straightforward. Flex duct, common in Leander attic installs, holds debris differently and takes longer to clean without damaging the liner.
- Debris type and depth. A duct with a light dust layer takes one pass. A duct with compacted pet hair, insulation fragments from a previous attic disturbance, or visible biological growth takes more time and different technique. The camera tells us which situation we’re looking at before the price is written.
- Access difficulty. Return ducts in crawlspace-fed systems or through complex ceiling configurations in Leander’s two-story homes take longer to access and navigate than a straightforward first-floor return run.

FAQs – Return Duct Cleaning
What is a return duct, and why does it need separate cleaning?
A return duct is the section of your HVAC system that pulls air from your living space back to the air handler to be filtered and conditioned before recirculation. It needs separate attention because return ducts operate under negative pressure, which means they actively draw debris inward – dust, dander, insulation particles, and anything else present in the air path. Over time, this material builds up at bends and inside the return plenum in ways that our Air Duct Cleaning services don’t address unless specifically targeted. In Leander homes where systems run hard through eight months of cooling season, return ducts can accumulate several years of compressed debris before showing visible symptoms at the grille. Call (737) 252-1285 if you want a camera inspection to see what’s actually there.
How much does return duct cleaning cost in Leander?
Return duct cleaning in Leander runs between $120 and $280 for most residential systems. The low end covers a single return with a standard run and light debris. The high end reflects multi-return systems with heavy contamination or difficult access configurations. Your exact price is written before any work starts – that’s how every CleanRun job works, and there are no add-ons after the camera goes in. Call (737) 252-1285 to schedule a camera inspection and receive a written price the same day.
Can you clean return ducts without cleaning the full system?
Yes, return duct cleaning can be done as a standalone service. That said, the camera inspection often shows us that the return and supply sides have similar debris levels – which makes sense, since they share the same air handler and the same years of use. We’ll show you what the camera found in both sections and give you a written price for each option. The decision is yours. Many Leander homeowners start with return duct cleaning after noticing filter or air quality issues, then schedule full system cleaning once the inspection confirms supply duct condition. You can see the full scope of what a complete job covers on our Air Duct Cleaning in Leander page.
How long does return duct cleaning take?
Most return duct cleaning jobs in Leander take between 90 minutes and three hours. A single-return system in a standard single-story home is on the shorter end. A multi-return two-story home with heavy debris or flex duct configuration runs closer to three hours. The camera inspection adds roughly 20-30 minutes to the front of the job, and the post-cleaning photo pass adds another 15-20 minutes at the end. Both are included in the quoted time and price – not billed separately. If your schedule is specific, let us know when you call (737) 252-1285 and we’ll give you an honest time estimate based on your system before you book.
Why Leander Homeowners Choose CleanRun for Return Duct Work
Leander’s growth has been fast. The city’s population has roughly tripled since 2010, and a large share of that growth came through planned developments with similar home configurations – two-story layouts, attic-mounted air handlers, and flex duct runs that builders installed quickly and buyers rarely inspect. That combination – attic heat, flex duct, and years of Central Texas cedar and oak pollen cycling through the system – creates return duct conditions that are genuinely different from what you’d find in a Colorado or Pacific Northwest home.
We’ve cleaned return duct systems in Leander neighborhoods from Crystal Falls to Travisso to the newer builds near Bryson, and the pattern we see consistently is a clean filter cabinet paired with a return plenum that hasn’t been touched since the home was built. The filter does what it can. What gets past it lands in the return plenum and stays there until someone with a camera and the right equipment gets to it.
Tomas Reyes built CleanRun on a simple operating principle: show the customer the evidence before saying a word about what needs to happen. That’s why the camera goes in first, why the price is written before a panel comes off, and why the photo record comes out with the crew when the job is done. The work should be documentable – if it isn’t, it probably wasn’t done right.
Every technician who works a CleanRun job in Leander is background-checked, uniformed, and identified by name before arrival – Haven Standard Clause 3: Verified Crews. The equipment on the truck includes Rotobrush and Nikro units, not shop vacuums in branded vans. And the 365-Day Done Right Promise is a written commitment on every job, not a line in a marketing paragraph.
