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.

AfterSupply Duct Cleaning in Austin, TX
Supply duct cleaning focuses on the duct runs that actually push conditioned air into your living spaces – the side of your HVAC system that directly determines what you breathe in every room. In Austin homes, supply ducts typically accumulate a distinct mix of fine limestone dust, cedar pollen, and fibrous debris that the return side never sees. CleanRun Duct Repair & Cleaning has been photographing the inside of these runs since 2013, and Video Inspection rarely lies about what’s been sitting in there.
Supply duct cleaning in Austin costs between $280 and $650 for most single-story homes, depending on the number of duct runs, duct material, and degree of debris accumulation; see How Much Does Air Duct Cleaning Cost in Austin, TX? (2026 Price Guide) for full pricing factors. Most jobs are completed in three to four hours, and every price is written before any panel comes off – no exceptions.

What Supply Ducts Actually Do – and Why They Get Dirtier Than You’d Think
Your HVAC system has two duct networks. The return side pulls air from your rooms back to the air handler. The supply side – the subject of this page – pushes that conditioned air back out through registers (the vents you can see on your ceiling or floor). Because supply ducts are under positive pressure, air is always moving outward through them. That sounds like it would keep debris from settling, but in practice it doesn’t work that way.
At startup and shutdown, the pressure in the duct fluctuates. Debris that was carried in during installation or infiltration through loose connections settles in the horizontal runs and at every elbow. In Austin’s climate, attic temperatures regularly exceed 140 degrees Fahrenheit from May through September. That heat causes flexible duct material – the corrugated silver tubing used in most Austin homes built after 1990 – to expand, contract, and develop micro-cracks at connection points. Those cracks let attic air and its associated particulate in. What goes in doesn’t come back out on its own.
Austin’s cedar season (roughly December through February) and its persistent limestone dust make the contamination profile here different from what technicians see in, say, Houston or San Antonio. We find the two often combine with HVAC system moisture at cooling coil connections to form a paste-like deposit at the first elbow of supply runs – the section closest to the plenum (the central distribution box the air handler feeds). That deposit narrows the duct’s effective diameter and is invisible without a camera.
When You Need Supply Duct Cleaning
- Rooms that won’t reach temperature. If a bedroom in your Mueller or Tarrytown home is consistently warmer or cooler than the rest of the house by three or more degrees, restricted supply duct flow is a likely cause – often a partial blockage at an elbow or a collapsed section of flex duct near the register.
- Fine dust on surfaces within days of cleaning. Supply registers push air at velocity. If there’s debris in the supply runs, that velocity deposits it on horizontal surfaces – bookshelves, TV screens, nightstands – faster than a dirty return side would. If you’re dusting the same surfaces every three to four days, the supply side is usually where the problem lives.
- You’ve recently had renovation work done. Drywall dust, insulation fibers, and sawdust are dense enough to settle in supply runs and stay there. Austin’s construction pace – especially in neighborhoods like East Austin, Brentwood, and the Domain corridor – means a significant number of the homes we visit have had some level of renovation since their original build.
- Your home is more than eight years old and has never had duct work photographed. Homes built between 2005 and 2018 in the greater Austin metro often used flex duct runs with factory-recommended but field-variable installation methods. After eight or more years, the liner material degrades in ways you can’t detect from the register without a camera.
- Cedar or allergy season triggers noticeably worse indoor symptoms. If household members with cedar or grass pollen sensitivities feel significantly worse indoors than outdoors during Austin’s cedar season, the supply ducts are a plausible amplifier – they distribute whatever has accumulated in the system into every occupied room with every cycle.
- You’ve bought a home and don’t have documentation of prior duct service. Supply duct cleaning history is almost never disclosed in Texas real estate transactions. If you don’t have a written record with photos, you don’t know what’s in there.
BeforeAfterOur Supply Duct Cleaning Process
-
Written price, delivered before work begins
We assess your home’s duct layout – number of supply runs, duct material, accessibility, and any visible signs of damage – and give you a written price. This is Haven Standard Clause 1: no work starts without a number you’ve agreed to in writing. The assessment takes fifteen to twenty minutes. If our number doesn’t work for you, you owe us nothing.
-
Pre-cleaning camera inspection of every supply run
Before any cleaning equipment is connected, a rigid inspection camera goes into each supply run from the register end. The footage is recorded and becomes the “before” portion of your Documented Photo Record. This step exists specifically so you can see what was actually in your ductwork before we touched it – not after, when there’s nothing left to see. In Austin attic-fed systems, the camera regularly shows debris accumulation at the first and second elbow that would be impossible to confirm or quantify any other way.
-
Negative-pressure extraction
Negative-pressure extraction means we establish a powerful vacuum at the plenum end of the supply system before we agitate anything. The vacuum – created with Nikro professional-grade equipment – holds the entire supply-side duct network under suction, so that when the agitation brush moves through a run, loosened debris travels toward the collection point rather than redistributing into your home. This is the technical difference between an NADCA-referenced cleaning method and a shop-vac with a brush attached to it. The latter is common in the Austin market; the former is what we use.
-
Rotary brush agitation through each supply run
With the system under negative pressure, a Rotobrush agitation head travels through each supply run from the register back toward the plenum. The rotary action breaks up the paste-like debris deposits at elbows – the ones that accumulate from Austin’s cedar pollen and limestone dust mixing with coil moisture – and draws them into the collection system. We work every run individually. No run is skipped.
-
Post-cleaning camera verification of every supply run
After extraction is complete on each run, the camera goes back in. The footage becomes the “after” portion of your Documented Photo Record. You receive both before and after images for every duct run we cleaned – not a sample, every run. The record is delivered to you as a standard part of the job, not as an add-on.
-
Written summary and 365-Day Done Right Promise
At job completion, you receive a written summary of what was found, what was done, and the condition of each run post-cleaning. Every job is covered by the 365-Day Done Right Promise: if the work is not right, we make it right – and that’s in writing, not subject to manager approval or expiration fine print.
Supply Duct Cleaning Pricing in Austin
Supply duct cleaning in Austin typically falls between $280 and $650 for single-story homes and $420 and $900 for two-story homes with larger supply networks; our Air Duct Cleaning services cover every home type. Every price is written before work begins – that’s not a marketing line, it’s Haven Standard Clause 1 and it applies to every job without exception.
| Home Configuration | Typical Price Range | Notes |
|---|---|---|
| Single-story, up to 10 supply runs | $280 – $420 | Most common for Austin homes under 1,800 sq ft |
| Single-story, 11-18 supply runs | $400 – $580 | Typical for 1,800-2,800 sq ft builds in areas like Round Rock and Cedar Park |
| Two-story, up to 20 supply runs | $420 – $700 | Includes attic-fed and closet-based air handler configurations |
| Two-story, 20+ supply runs or zoned system | $650 – $900 | Zoned systems with multiple plenums require separate extraction setups |
| Post-renovation cleaning (heavy debris load) | Add $80-$180 | Applicable when drywall dust or insulation is confirmed in supply runs |
What affects the final price
- Number of supply runs. Each run is cleaned and photographed individually. More runs means more time and more equipment setup.
- Duct material. Rigid metal duct (common in Austin homes built before 1985) accepts the rotary brush without restriction. Flex duct requires a modified approach at connection points to avoid tearing the liner.
- Debris load. Homes coming out of renovation, or homes where cedar season debris has been accumulating for a decade, take longer to clean and verify. The camera tells us the degree before we price it.
- System configuration. Attic-based air handlers in Austin – common in ranch-style homes across the Allandale and Crestview areas – require different access than closet-mounted systems. Both are serviceable; access time is factored into the written price.
- Combination with return duct cleaning. If you’re having both supply and return sides cleaned in the same visit (which is the more thorough approach), the combined price is lower than two separate service calls.

FAQs – Supply Duct Cleaning in Austin
How is supply duct cleaning different from return duct cleaning?
Supply duct cleaning addresses the pressurized runs that push conditioned air into your rooms; return duct cleaning addresses the runs that pull air back to the air handler. Supply runs accumulate debris differently because air moves outward through them at velocity, causing particulate to settle at elbows and low points rather than being continuously carried toward a filter. In Austin homes, supply runs tend to show heavier localized deposits – especially at the first elbow off the plenum – while return runs show a more even coating of general household dust. Both sides matter, but if indoor air quality or uneven room temperatures are the presenting problem, the supply side is usually where the camera finds the most significant obstruction.
How much does supply duct cleaning cost in Austin?
Supply duct cleaning in Austin costs between $280 and $900 depending on the number of supply runs, the duct material, and the debris load confirmed by pre-cleaning camera inspection; for a full breakdown, see How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Austin, TX. Single-story homes with up to 10 supply runs typically come in between $280 and $420. The written price is delivered before work begins, every time – call (737) 243-9544 for a scheduled in-home assessment and written estimate at no charge.
Can supply duct cleaning fix uneven temperatures between rooms?
Supply duct cleaning can fix uneven temperatures when the root cause is a restricted or obstructed supply run – which is a common finding in Austin homes, particularly in rooms served by long flex duct runs with multiple elbows. If the camera shows a partial blockage or a collapsed duct section, cleaning or repair will typically restore airflow balance to that room. If the temperature difference persists after cleaning, the cause is more likely a duct sizing issue or a damper problem, and we’ll document that finding in writing so you know what the next step is. Cleaning won’t fix a design problem, and we won’t tell you it will.
How long does supply duct cleaning take in an Austin home?
Most supply duct cleaning jobs in Austin take between two and a half and four hours for a single-story home with up to 15 supply runs. Two-story homes or homes with zoned systems typically run three and a half to five hours. The time includes the pre-cleaning camera inspection, the negative-pressure extraction and brush agitation of every run, and the post-cleaning camera verification that produces your Documented Photo Record. We don’t schedule jobs back-to-back in a way that forces a technician to skip verification steps – the photo record for every run is a standard deliverable, not optional.
Why CleanRun for Supply Duct Cleaning in Austin
CleanRun has been operating in Austin since 2013. In that time, we’ve served more than 52,000 homes across the metro, from Barton Hills to Pflugerville, and every single job came with a written price before work started and a documented photo record when the crew left. That’s not a recent policy – it’s been the standard since the first job.
Tomas Reyes built CleanRun around a straightforward premise: the only way to sell duct cleaning honestly is to show the customer what’s inside the duct before saying anything else. The camera goes in first, the photo record comes out last, and the written price sits in the customer’s hand before any panel is removed. That sequence hasn’t changed.
The equipment we use – Nikro extraction units, Rotobrush agitation heads, Abatement Technologies negative-pressure systems – is trade-recognized and independently verifiable. You can look up what those brands are and what they’re designed to do before you agree to a price. We prefer it that way.
Every technician arriving at your home has passed a background check, wears a uniform, and is identified by name before arrival. That’s Haven Standard Clause 3: Verified Crews. It’s a documented commitment, not a marketing phrase.
For Austin homeowners researching what’s in their supply ducts, the CleanRun home page gives you the full picture of how we operate and what every service includes as a standard deliverable.
