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 New Braunfels, TX
Supply duct cleaning targets the duct runs that carry conditioned air from your HVAC system outward to every room in your home – the side of the system that deposits whatever it carries directly into your living space. In New Braunfels, where summer heat runs long and cedar pollen seasons hit hard, those supply runs accumulate a specific mix of debris: fine limestone dust from the Hill Country soil, pollen, construction particulate in newer Veramendi and Meyer Ranch builds, and in older homes near the Comal River corridor, years of moisture-assisted buildup at the first elbow off the plenum. Supply duct cleaning is the sub-service that addresses that specific pathway – not the return side, not the blower housing, but the air delivery network your system uses to push conditioned air into every room. For a complete overview of what we offer, see our Air Duct Cleaning services.
CleanRun Duct Repair & Cleaning has documented the inside of supply duct systems in New Braunfels homes since 2013. Every job we do here – from a compact two-bedroom near downtown to a 4,000-square-foot home in Vintage Oaks – starts with a written price before any panel comes off and ends with a Documented Photo Record of every run, before and after. That record is delivered to you as a standard part of the job, not as an add-on. If you want to understand what our full Air Duct Cleaning in New Braunfels scope covers, that page lays it out completely. For questions specific to your supply system, call (830) 549-6847 – a live person answers every call.
What Supply Ducts Actually Do (and Why They Get Dirty)
Your HVAC system has two duct networks. The return side pulls air from your rooms back to the air handler. The supply side pushes conditioned air from the plenum – the central distribution box attached directly to your air handler – through a series of duct runs that terminate at the supply registers you see in your ceilings and floors. Every cubic foot of air that reaches a room in your home has traveled through those supply runs first.
Because supply ducts are under positive pressure – meaning air is being pushed through them rather than pulled – debris that enters the system tends to deposit at bends, at joints where sections connect, and at damper locations where airflow slows. In New Braunfels specifically, three conditions accelerate that buildup:
- Caliche and limestone dust: The fine particulate that characterizes Hill Country soil gets into return grilles and migrates into the supply side over time, particularly in homes without high-efficiency filtration.
- Cedar and oak pollen: Comal County sees two distinct heavy pollen seasons. Mountain cedar peaks December through February; oak runs March through May. Homes where windows are opened during mild stretches between these seasons introduce substantial pollen that filter media doesn’t always capture fully.
- Construction debris in newer subdivisions: In Veramendi, Meyer Ranch, and the newer sections of Gruene Heights, supply ducts in homes built between 2016 and 2024 regularly show drywall dust, insulation fiber, and spray foam residue at the first two elbows off the plenum – debris left from installation that a builder walk-through never addressed.
None of this is unusual, and none of it is an emergency on its own. But it does mean the air moving through your supply system is carrying that material into your rooms.
When You Need Supply Duct Cleaning
No single symptom is definitive on its own. But these are the situations where supply duct cleaning is the right call in New Braunfels:
- Visible debris at supply registers: If you see dark streaking or particulate buildup on the ceiling or wall around supply registers – not the return grilles, but the smaller vents that blow conditioned air – the supply runs are almost certainly carrying material that is depositing as airflow slows at the register opening.
- Uneven room temperatures in multi-zone homes: A back bedroom in a one-story home near FM 306 that consistently runs 4 to 6 degrees warmer than the thermostat setting can indicate a partially restricted supply run. Debris buildup at a mid-run elbow reduces airflow volume without triggering any system fault code.
- A recent renovation or new build move-in: Drywall work, tile cutting, and insulation installation all generate fine particulate that enters the supply system through open register boots before grilles are seated. We see this consistently in homes in Creekside and Canyon Lake Gorge subdivisions that had cosmetic renovations done before resale.
- Post-pest or rodent activity: Pest control services in New Braunfels regularly document rodent entry through supply duct joints in attic-run systems. After the intrusion is resolved, the supply runs need documentation and cleaning before the system is run normally again.
- High-allergy household where filtration has been inconsistent: If filter changes were missed for an extended period – a common situation in vacation or rental properties near Schlitterbahn or Landa Park – the supply side will have accumulated pollen and dust that no filter upgrade alone will remove.
- Purchase of a home built before 2000 with original ductwork: In older New Braunfels neighborhoods like Westside and the blocks east of Loop 337, homes with original flex duct or galvanized steel supply runs may not have been cleaned in decades. A camera inspection before any cleaning is the only way to document actual conditions.
BeforeAfterOur Supply Duct Cleaning Process
Every step below is documented with photography, including Video Inspection footage. You receive that record when the job is complete.
- Written scope and price before work starts: We assess your home’s layout, count supply runs, note any access limitations, and deliver a written price – total, not hourly, not approximate. Under Haven Standard Clause 1, no work begins before you have that number in writing. There is no “we’ll know more when we open it up” pricing at CleanRun.
- Pre-cleaning camera inspection of each supply run: Using a flexible inspection camera, we photograph the inside of each supply duct run from the plenum outward to the register boot. These before-images establish actual conditions: you can see the debris layer, any visible gaps at joints, and any standing moisture if it exists. This is the photo that means something – the one taken before we touch anything.
- Negative-pressure containment setup: We connect a negative-pressure extraction unit – typically our Nikro or Rotobrush equipment depending on your system’s duct diameter and configuration – to the plenum or a designated access point. Negative pressure means the interior of the duct system is maintained at below-ambient air pressure during cleaning, so dislodged debris moves toward the extraction unit rather than toward your rooms. Your living space stays outside the process.
- Mechanical agitation of each supply run: Compressed air whips or rotary brush attachments are fed through each supply run from the register boot back toward the plenum, breaking up compacted debris at elbows and joints where it tends to accumulate. In New Braunfels homes with attic-run flex duct, we adjust brush pressure to avoid tearing the inner liner – a damage pattern we see regularly when vacuum-only operators work too aggressively.
- Post-cleaning camera verification: After extraction is complete, we run the inspection camera through each supply run again. The after-image documents what was removed. If a run still shows debris that the cleaning pass didn’t clear – sometimes the case at a tight 90-degree elbow – we document it and address it before the job is signed off.
- Documented Photo Record delivered to you: Before and after images from every run, organized by location in the house, are delivered as part of your standard job record. You can see exactly which register runs are clean and which, if any, had conditions that warrant follow-up. This is what accountability looks like after a truck leaves.
Supply Duct Cleaning Pricing in New Braunfels
Supply duct cleaning in New Braunfels typically runs between $280 and $650 as a standalone service, depending on the factors below. If supply cleaning is part of a full whole-home air duct cleaning scope, the combined job typically falls between $450 and $950 for a single-family home. See How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - New Braunfels, TX for detailed pricing breakdowns.
| Factor | Typical Price Impact |
|---|---|
| Number of supply runs (vents) | Base price increases per run; most New Braunfels homes have 10-20 supply registers |
| Duct material (flex vs. rigid metal) | Rigid galvanized steel adds time; heavily corrugated flex duct in older builds adds 10-15% to labor |
| Attic vs. crawlspace routing | Attic-run systems in Hill Country homes add access time, particularly in summer months |
| Severity of buildup | Post-construction debris or multi-year accumulation requires more agitation passes per run |
| System age and access point availability | Pre-2000 systems may require cut-in access panels; that work is scoped and priced separately in writing |

FAQs – Supply Duct Cleaning
What is the difference between supply duct cleaning and return duct cleaning?
Supply ducts carry conditioned air from your HVAC system to each room; return ducts carry room air back to the system for reconditioning. They’re separate physical pathways, and they accumulate different types of debris in different locations. Supply duct cleaning focuses on the runs downstream of the plenum – the ones that end at your ceiling or floor registers – which is where pollen, construction dust, and fine particulate deposit as airflow slows before exiting into a room. A full air duct cleaning scope typically addresses both sides. If your concern is specifically about what’s being delivered into your rooms, supply cleaning is the relevant scope. Call (830) 549-6847 and we’ll tell you in writing exactly what your system needs before any work starts.
How long does supply duct cleaning take in a typical New Braunfels home?
Supply duct cleaning alone in a standard New Braunfels single-family home – typically 10 to 18 supply runs – takes between two and four hours from setup to photo record delivery. Larger homes in Vintage Oaks or River Chase with 20 or more supply runs, or homes where attic access is limited, can run five to six hours. We give you a time estimate along with your written price before the job starts, so you can plan your day. We don’t work on the clock – the job is done when the after-photos confirm the runs are clear.
Can supply duct cleaning improve my HVAC system’s airflow?
Yes, in cases where debris buildup has partially restricted one or more supply runs. A compacted debris layer at a mid-run elbow reduces the effective cross-sectional area of the duct, which means less air volume reaches the register – and the room. After cleaning, we’ve documented measurable airflow improvement at individual registers in New Braunfels homes where the supply runs hadn’t been serviced since original installation. That said, restricted airflow can also result from undersized ducts, damper issues, or equipment problems, and cleaning won’t correct those. Our camera inspection before cleaning helps identify which situation you’re actually dealing with.
Is supply duct cleaning covered by the 365-Day Done Right Promise?
Yes. Every service CleanRun performs in New Braunfels is covered by the 365-Day Done Right Promise – if the work isn’t right, we make it right, backed in writing on every job. For supply duct cleaning specifically, the Documented Photo Record we deliver at job completion is what “right” is measured against. If a run that was photographed clean shows a problem within 365 days that traces back to our work, we address it. That’s not a policy subject to manager interpretation – it’s a written commitment on your job record.
Why New Braunfels Homeowners Choose CleanRun
The duct cleaning industry in Comal County has a specific problem: the $79 coupon truck. It shows up, runs a shop vac through a couple of registers, collects a check, and leaves nothing behind – no photos, no documentation, no way for a homeowner to verify that anything actually happened inside the ducts. We built CleanRun in 2013 as a direct response to that model.
Every technician who arrives at your door is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The equipment we use – Rotobrush and Nikro for mechanical agitation and negative-pressure extraction, Aprilaire and Honeywell components when air quality add-ons are relevant – is professional-grade equipment you can look up independently. We don’t ask you to take our word for it.
Across more than 52,000 homes served since 2013, every single one started with a written price and ended with a documented photo record. That’s not a differentiator we invented for a marketing page – it’s how we’ve run every job from the first one. The home page has a fuller picture of what the H.A.V.E.N. Standard covers across every service we offer.
