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 Round Rock, TX
Supply duct cleaning focuses specifically on the duct runs that push conditioned air from your HVAC system into each room of your home – the side of your duct system that delivers the air your family breathes every day. In Round Rock, where homes built between 2000 and 2020 in neighborhoods like Teravista, Forest Creek, and Brushy Creek often have 12 to 20 individual supply runs branching off a central plenum, a single dirty or partially blocked run can quietly undercut your system’s efficiency while pushing particulates directly into your living space. CleanRun Duct Repair & Cleaning has photographed and cleaned supply ducts in over 52,000 homes since 2013, and every job starts with a written price for our Air Duct Cleaning services – before a single panel comes off.
If you want the full picture of what’s happening in your duct system, our Air Duct Cleaning in Round Rock service covers both supply and return sides together. But when a technician’s camera has already identified the supply runs as the specific source of a problem, a targeted supply duct cleaning is the right starting point – and that’s exactly what this page covers.

What Supply Ducts Actually Do – and Why They Get Dirty
The supply side of your duct system carries air that has already passed through the filter and the air handler. That sounds clean – and it mostly is, early in a system’s life. The problem is that supply ducts in Central Texas homes experience a specific wear pattern that most homeowners don’t know about until they see the camera footage.
Round Rock sits at the edge of the Edwards Plateau, which means the area gets genuine seasonal swings: hot, dry summers that run the AC almost continuously, followed by winter cold snaps that push the furnace hard. That constant start-stop cycling creates pressure differentials inside the duct system. Over years, those pressure changes pull fine dust and debris through any small gap in a duct joint or connection – and into the supply runs themselves. In newer construction where flex duct was used (the corrugated plastic tubing common in Round Rock homes built after 2005), the accordion interior surface grabs and holds that debris far more stubbornly than smooth metal ductwork does.
What we typically find when we run a camera through supply runs in Round Rock homes: dust-cake buildup at the first elbow off the plenum, insulation fibers that have worked loose from poorly sealed joints, and in homes with pets or recent renovation work, a more substantial layer of dander, drywall dust, or debris that has bypassed the filter at some point. The Video Inspection record – which every CleanRun customer receives as a standard deliverable – shows exactly what was there before we touched it.
When You Need Supply Duct Cleaning
- Rooms that never reach the set temperature. If a bedroom in Teravista is consistently 4 or 5 degrees warmer than the thermostat says, a partially blocked supply run is one of the first things to check. Debris buildup at an elbow can reduce airflow by 30 percent or more before anyone notices a visible symptom.
- Visible dust on supply registers within days of dusting. When conditioned air is carrying particulates through dirty supply runs, the register face becomes a collection point. If you’re wiping the same grilles every week, the dust is coming from inside the duct, not just the room.
- A musty or stale smell that appears when the AC kicks on. Round Rock’s humidity levels between April and October create conditions where any organic debris inside a supply run – skin cells, plant material, dust mite waste – can develop an odor that the air handler then distributes through the house. The smell often clears within a few seconds as the air moves through, which makes it easy to dismiss. It shouldn’t be dismissed.
- Recent construction or renovation in the home. Drywall dust is fine enough to pass through or around a filter and settle into supply runs. If your home in Forest Creek had any work done in the last two years – even a single room – supply duct inspection and cleaning is worth scheduling. We find construction debris in supply runs regularly, and the homeowner usually had no idea it was there.
- A system that was never cleaned after purchase. Many Round Rock homeowners who bought between 2015 and 2025 received no documentation on whether the duct system was ever professionally cleaned. If you don’t have a written record showing the previous clean date and method, assume it hasn’t been done to a documented standard.
- Higher-than-expected energy bills without an obvious cause. A partially obstructed supply run makes your HVAC system work harder to maintain temperature. If your Oncor bill is climbing but your usage habits haven’t changed, the duct system is worth examining before you call for an HVAC service call.
BeforeAfterOur Supply Duct Cleaning Process
- Written price before anything else. Under Haven Standard Clause 1, CleanRun delivers a written price before any work begins – no exceptions. A technician assesses your supply duct configuration, counts the runs, notes the material type (flex duct versus sheet metal versus fiberglass-lined), and puts a number on paper. You review it. If you agree, work starts. If you don’t, nothing happens and you owe nothing.
- Camera inspection of each supply run. Before any cleaning equipment enters the duct, we run a camera through each supply run and photograph what’s there. This is not a sales tool – it is the before record that makes the after record meaningful. In Round Rock homes with 14 or more supply runs, this step alone can take 45 minutes. We take the time because a documented baseline is the whole point.
- Negative-pressure extraction setup. Negative-pressure extraction means we connect a high-powered vacuum unit to the supply system, creating suction that pulls debris toward the collection point rather than pushing it into your living space. We use Nikro and Abatement Technologies equipment for this – both are trade-recognized systems that move enough CFM (cubic feet per minute of airflow) to handle the duct volumes typical of Round Rock’s two-story homes. The duct system is put under continuous negative pressure before any agitation begins.
- Mechanical agitation of each run. With the system under negative pressure, a technician uses a rotary brush system to break debris loose from the duct walls, working from the register opening back toward the plenum. For flex duct, the brush selection and technique are different than for rigid sheet metal – the accordion surface requires a softer approach to avoid damaging the liner. Our technicians know the difference because they see both material types on every shift in Round Rock.
- Register and boot cleaning. The register boot – the metal box the register grille attaches to – is a debris trap that most shop-vac-style cleaning visits miss entirely. We remove each supply register, clean the boot interior by hand, and reinstall the register before moving to the next run. This step is included in every CleanRun supply duct cleaning job, not offered as an add-on.
- Post-cleaning camera pass and photo record delivery. After every supply run is cleaned, we run the camera through again and photograph the result. Both sets of images – before and after – are delivered to you as part of the standard job record. You can see what was there and what isn’t anymore. That record is yours to keep, and it forms the basis of the 365-Day Done Right Promise: if the work isn’t right, CleanRun makes it right, in writing, not subject to manager approval.
Supply Duct Cleaning Pricing in Round Rock
Supply duct cleaning in Round Rock typically runs between $180 and $420 for a standard residential job, depending on the factors below. See How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Round Rock, TX for a detailed breakdown. That range covers homes with 8 to 20 supply runs – which covers the large majority of single-family homes in Round Rock’s established subdivisions.
| Factor | Typical Range Impact |
|---|---|
| Number of supply runs (8-12 runs) | $180 – $260 |
| Number of supply runs (13-20 runs) | $260 – $360 |
| Flex duct vs. rigid sheet metal (flex takes longer) | Add $20 – $40 per job |

| Two-story home with supply runs in unconditioned attic space | Add $20 – $40 |
These numbers reflect Round Rock’s current market. The written price you receive before work starts will be specific to your home’s configuration – not an estimate that grows once the panels come off. That’s Haven Standard Clause 1, and it applies to every job without exception.

What Makes Round Rock Supply Ducts Different
Round Rock’s building boom between 2003 and 2018 produced a large number of homes where the supply duct system was installed quickly under production-build conditions. That often means flex duct connections at the plenum that were secured with a single layer of mastic or metal tape rather than the double-layer spec, and supply runs that were routed through attic spaces without adequate insulation at the connection points. By the time a home in Brushy Creek or Stone Canyon is 12 years old, those joints have experienced hundreds of thermal expansion and contraction cycles – and some of them have opened slightly.
When a supply duct joint opens even a quarter inch in an unconditioned attic, two things happen. First, conditioned air leaks into the attic rather than reaching the room. Second, attic air – which in Round Rock summers can reach 140 degrees Fahrenheit – is drawn into the supply run during pressure fluctuations. That attic air carries fine fiberglass particles from the attic insulation, and those particles end up in the duct and eventually in the room. If your camera footage shows a gray, fibrous buildup in the supply runs near the plenum, that’s usually what you’re looking at.
Supply duct cleaning addresses the debris that’s already there. If the camera also shows open joints or disconnected sections, that’s a duct repair and sealing issue – which is a separate service and a separate written price, never folded into the cleaning quote without your agreement.

The H.A.V.E.N. Standard and What It Means for Your Job
Every CleanRun technician operates under the H.A.V.E.N. Standard – a documented framework that covers how technicians are screened, how they identify themselves before arrival, how pricing is presented, and what documentation leaves with the customer after the job. For supply duct cleaning specifically, the clauses that matter most are Clause 1 (written price before work starts) and Clause 3 (verified crews: background-checked, uniformed, identified by name before they show up at your door).
Tomas Reyes built CleanRun’s operating standards around the idea that a homeowner shouldn’t have to take a company’s word for anything. The written price, the camera record, and the 365-Day Done Right Promise are designed so that if a question comes up three months after the job, there’s a paper trail to answer it. That’s not a marketing angle – it’s how the business has operated since its first job in 2013.
FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Round Rock?
Supply duct cleaning in Round Rock typically costs between $180 and $420 for a standard residential job with 8 to 20 supply runs. The exact number depends on how many runs your home has, whether the ductwork is flex or rigid metal, how long it’s been since the last cleaning, and whether the system is in a single-story or two-story layout. CleanRun delivers the specific written price before any work begins – that number doesn’t change once the job starts. Call (737) 259-5752 and a live person will walk through your home’s configuration with you to get to a number.
Is supply duct cleaning different from return duct cleaning?
Yes, they are distinct parts of the system. Supply ducts carry conditioned air from the air handler out to each room; return ducts pull room air back to the system to be filtered and reconditioned. Supply runs are typically smaller in diameter, more numerous, and distributed throughout the home’s living areas, while return ducts are fewer and larger. Debris in supply runs gets pushed directly into the room – which is why visible dust on register faces and uneven room temperatures are supply-side symptoms. A full Air Duct Cleaning in Round Rock job covers both sides, but if a camera inspection has already identified the supply runs as the specific problem, starting there is the right call.
How long does a supply duct cleaning take in a typical Round Rock home?
A typical Round Rock home with 12 to 16 supply runs takes 2.5 to 4 hours when the job is done to a documented standard. The camera pass before cleaning, the negative-pressure setup, the mechanical agitation of each run, and the post-cleaning camera pass all take real time. Jobs that are completed in under 90 minutes – which is common in the $79 coupon end of the market – are not doing all of those steps. If a quote seems fast or cheap relative to the scope, ask specifically whether a pre-cleaning camera record is included and what equipment will be used.
How often should supply ducts be cleaned in Round Rock?
Most Round Rock homes benefit from supply duct cleaning every 3 to 5 years under normal conditions. Homes with pets, recent renovation work, high occupancy, or documented allergy or asthma conditions in residents are better served by a 2 to 3 year interval. Round Rock’s spring cedar and oak pollen seasons can also push more particulate into the duct system on homes where doors and windows are opened frequently in February and March, which is worth factoring into your schedule. The clearest guide is the camera record from the last cleaning – if the before photos from that job showed moderate buildup, plan for 3 years. If they showed heavy buildup, 2 years is the more conservative and appropriate interval.
