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.

If you’ve seen $79 coupons advertised around San Antonio, keep reading – that section is below, and it comes with a camera photo to explain what that price actually delivers.
Air Duct Cleaning Cost Breakdown in San Antonio (2026)
Air duct cleaning in San Antonio costs $299 to $699 for most single-family homes. Here’s how that breaks down by job type:

| Full HVAC system cleaning | $599 - $999 | Includes coil, blower, plenum, and all duct runs |
These are real San Antonio market numbers as of 2026, not national averages repackaged with a city name attached. The range on any individual job moves based on a few factors we’ll explain in the next section – but the written price you get from CleanRun before work starts is the price you pay. That’s not a promise buried in fine print; it’s Haven Standard Clause 1, applied to every job since 2013.
About That $79 Coupon
San Antonio homeowners run into low-price duct cleaning offers constantly – on door hangers in Stone Oak, on Facebook ads targeting Helotes zip codes, occasionally stapled to pizza boxes. The $79 offer almost always works the same way: a shop vac is connected to one or two registers, the technician spends 45 minutes on-site, and the upselling starts the moment they’re inside your house. Mold. Debris. Urgent code concerns. By the time the truck leaves, the invoice is closer to $400 anyway – except there’s no written scope, no before photo, and no accountability for what was or wasn’t cleaned.
CleanRun’s camera goes inside every duct run before work starts. That image is part of your documented photo record – a deliverable you keep, not a sales prop we show you once. If a duct run is clean, the photo shows it’s clean, and we’ll tell you so in writing. If there’s a 2-inch debris pack sitting at the elbow off the main trunk line (which we see regularly in older construction around Monte Vista and Mahncke Park), the photo shows that too, along with exactly what we’ll do about it and what it costs.
What Affects Air Duct Cleaning Pricing in San Antonio
No two San Antonio homes have identical ductwork, and pricing reflects that. These are the six factors that move the number up or down on a CleanRun written quote:
- Number of supply and return vents: The most direct driver of labor time and price. A 1,400 sq ft home in Woodlawn Hills might have 10-12 vents; a 3,200 sq ft two-story in Cibolo might have 24 or more. We count every vent before we quote, not after.
- System age and duct material: Older San Antonio homes – particularly those built before 1990 in areas like Olmos Park, Alamo Heights, and the King William Historic District – sometimes have ductwork made from duct board or older flex duct that’s degraded over decades. That material requires slower, more careful negative-pressure extraction to avoid tearing, which adds time. Newer rigid metal systems in Alamo Ranch or The Dominion neighborhoods are typically faster to clean.
- Accessibility: Attic-mounted ductwork in a hot San Antonio summer or a crawl-space system under a pier-and-beam foundation in Tobin Hill takes longer to work in than a straight basement run. Labor is time, and time is part of the price.
- Build-up level and contamination type: There’s a meaningful difference between routine dust accumulation after 3-4 years and a duct system that was never cleaned after a 2019 renovation, has a history of pest activity, or shows visible microbial growth at the registers. Heavy contamination jobs require longer extraction cycles and additional passes, and that’s reflected in the written scope.
- San Antonio’s climate and humidity pattern: The city sits at the edge of two distinct air masses, which means spring and fall bring significant humidity swings. Ducts in homes without properly maintained filters tend to accumulate particulate faster than equivalent square footage in drier markets like El Paso or Lubbock. If your system ran through a summer with a failed or missing filter – which we see in San Antonio rentals regularly – the build-up can be substantial by fall.
- Add-on services: Dryer vent cleaning, sanitizing, coil cleaning, and duct sealing are each priced separately and offered only when the camera shows a reason for them. No technician at CleanRun quotes an add-on without showing you the documentation that supports it.
BeforeAfterThe Difference Between a Real Cleaning and a Vacuum-Noise Visit
This matters more than most pricing comparisons, so it gets its own section.
NADCA (the National Air Duct Cleaners Association) defines a proper cleaning as source removal: every accessible surface of the air distribution system, cleaned using negative-pressure extraction equipment powerful enough to pull debris through the duct and into a contained waste system without redistributing it into the living space. That’s what professional-grade equipment from Rotobrush and Nikro is built to do – truck-mounted or portable units that create true negative pressure through the system, combined with mechanical agitation at each duct run so debris actually releases from duct walls instead of just getting disturbed and resettled.
A shop vac with a hose pushed into a register opening does not do that. It creates localized suction at one point and blows uncaptured particulate into the room through every other open register. The noise is convincing. The result isn’t.
When you hire Air Duct Cleaning in San Antonio through CleanRun, the equipment that shows up is Rotobrush or Nikro – named brands you can look up independently. The photo that goes into your job record shows the inside of each duct run, before and after. The difference between those two images is the documentation of what actually happened.
How to Save on Air Duct Cleaning Without Cutting Corners
There’s a right way to spend less on duct cleaning and a way that ends up costing more. Here’s the practical version:
- Bundle with dryer vent cleaning. If your dryer vent hasn’t been cleaned in more than a year, doing both on the same visit reduces the overall cost compared to scheduling two separate trips. The technician is already on-site with the equipment. San Antonio’s humidity means dryer vent lint packs down faster than in drier climates, so this combination tends to make sense for most homeowners.
- Don’t wait until there’s a symptom. Homeowners who call CleanRun after noticing reduced airflow, visible debris at registers, or musty odors from vents are usually dealing with heavier build-up than someone who schedules every 3-4 years on a routine basis. More build-up means longer labor time and a higher price. Routine maintenance costs less than remediation.
- Ask for a second opinion before you commit to a competitor’s upsell. If a company has already been in your home and told you that you need $1,200 in sanitizing, duct lining, or “UV treatment,” CleanRun will put our own written number next to their quote at no charge. That’s a standing offer – no appointment required to get the comparison.
- Check your filter change history before the visit. A 1-inch filter that hasn’t been changed in 8 months in a San Antonio summer has likely allowed more particulate to reach the duct walls than a properly maintained MERV-8 filter changed every 60 days. If you’re behind on filter changes, know that upfront so it’s not a surprise on the written quote.
- Get a written price before any work starts – from anyone you hire. This applies whether you hire CleanRun or someone else. If a company won’t give you a written price before opening your system, that’s the only information you need to make your decision. Haven Standard Clause 1 is the reason we put it in writing every time: a price you didn’t agree to in writing is a price you don’t owe.

What CleanRun’s Written Price Actually Covers
When Tomas Reyes built the pricing structure at CleanRun, the goal was straightforward: a customer reading the written quote should be able to tell exactly what is being cleaned, what equipment will be used, and what happens if the result doesn’t hold. Here’s what’s included in a standard CleanRun air duct cleaning job at the quoted price:
- Pre-inspection camera footage of every accessible duct run, included in the written job record
- Negative-pressure extraction using Rotobrush or Nikro professional-grade equipment
- Mechanical agitation at each supply and return run to release built-up particulate from duct walls
- Cleaning of the plenum (the central distribution box the system moves air through) as a standard line item, not an add-on
- Post-cleaning camera footage of every duct run cleaned, delivered as part of the documented photo record
- Written scope of work and written price, signed before work starts
- 365-Day Done Right Promise: if the cleaning doesn’t hold or wasn’t completed to the written scope, CleanRun makes it right – in writing, not subject to manager approval
If a technician finds something during the inspection that changes the scope – a disconnected duct run behind the wall, microbial growth at the coil, a crushed flex duct section – you’ll see the camera image before you see an updated price. Nothing gets added to the job without a revised written quote and your agreement. That’s not an exception to the process. That is the process.
San Antonio-Specific Factors Worth Knowing
Most national pricing guides for duct cleaning don’t account for what’s different about San Antonio’s housing stock and climate. A few things that actually affect pricing and results in this market:
The Caliche and Clay Soil Issue
Homes built on San Antonio’s caliche-heavy soils – common across the Northside and in the Hill Country edge neighborhoods like Grey Forest and Leon Valley – sometimes develop minor foundation movement over time. That movement can affect ductwork connections, particularly in older homes with rigid metal duct systems. A disconnected duct section that’s been bypassing the filter for years tends to show heavy debris accumulation directly downstream of the gap. We document it, quote the repair, and clean it in sequence.
Post-Construction Debris in New Development Areas
San Antonio’s growth corridors – Converse, Cibolo, Schertz, Selma, and the outer Alamo Ranch developments – have seen significant new construction between 2020 and 2025. New construction duct cleaning is not the same as maintenance cleaning: drywall dust, insulation fibers, and construction particulate pack into new duct runs during the build, and many HVAC contractors don’t clean the system before the homeowner moves in. If your San Antonio-area home was completed after 2019 and the ducts haven’t been cleaned, the camera tends to find material that surprises people who assumed a new home meant clean ducts.
Humidity and Microbial Growth
San Antonio averages humidity levels that push into the 70-80% range during spring and early summer. Duct systems in homes without dehumidification or with undersized HVAC equipment running extended cycles create condensation conditions inside supply runs – particularly at elbows and low points in the duct path. That’s where we most often find early microbial growth. The camera shows it before we quote anything related to it. Abatement Technologies air scrubbers are available for jobs where airborne particulate management is part of the written scope.
Older Homes in Central San Antonio
The Monte Vista Historic District, Alta Vista, Lavaca, and parts of the East Side have housing stock dating to the 1930s and 1940s. Some of those homes have had ductwork added or modified multiple times across decades. It’s not unusual to find three different duct materials – original metal, 1970s duct board, and 1990s flex – all connected in the same system. That kind of mixed system requires more care and more time, and the written quote reflects it accurately after the inspection, not after the work starts.
How to Read a Competitor’s Duct Cleaning Quote
If you’re comparing CleanRun’s written price against another company’s estimate, here are the questions worth asking before you sign anything:
- Is the price written down before any work starts, or is it a verbal “starting at” number?
- Does the quoted price include the plenum, or just the individual duct runs?
- What equipment is being used – by brand name, not category?
- Will you receive before-and-after photos of every duct run as a deliverable you keep?
- Is there a written guarantee, and if so, what specifically does it cover and for how long?
- Are the technicians background-checked, and can you confirm the technician’s name before arrival?
Under Haven Standard Clause 3 (Verified Crews), every CleanRun commercial duct cleaning technician is background-checked, uniformed, and identified by name before the appointment. If you bring a competitor’s written estimate to us, we’ll put our own number next to it in writing – no charge, no pressure to book on the spot. That’s the Free Second Opinion offer, and it applies to any written estimate in San Antonio.
When Air Duct Cleaning Is Worth It (and When It Isn’t)
Tomas Reyes has been in San Antonio ducts since 2013. The honest version of this section: not every home needs duct cleaning right now, and CleanRun isn’t going to tell you otherwise.
Duct cleaning makes measurable sense when:
- The system hasn’t been cleaned in more than 4-5 years and the home has had pets, smokers, or a recent renovation
- The camera shows visible debris accumulation – typically more than 1/4 inch of particulate coating on duct walls
- There are occupants with documented respiratory sensitivities or allergies that have worsened despite other interventions
- The home was recently purchased and there’s no documented cleaning history
- Post-construction: the home was built within the last 5 years and the ducts have never been cleaned
- There’s visible debris or discoloration at supply registers
Duct cleaning is probably not the right priority if:
- The system was cleaned within the last 2-3 years, filters have been maintained consistently, and the camera shows only light surface dust
- The primary concern is HVAC efficiency – if that’s the driver, a coil cleaning and blower service typically delivers a clearer result than duct cleaning alone
If the pre-inspection camera shows a clean system, we’ll tell you in writing and you won’t pay for work that wasn’t needed. That’s not a business model built on volume – it’s the only model that makes sense if the documentation is real.
Air Duct Cleaning San Antonio: FAQs on Cost
How much does air duct cleaning cost in San Antonio in 2026?
Most San Antonio homes pay between $299 and $699 for a professional air duct cleaning. The majority of single-family homes in the 1,500-2,800 sq ft range – which covers most of the Northside, Far West Side, and the newer developments in Bexar County – come in between $399 and $549. Larger homes with dual HVAC systems, older ductwork, or significant build-up documented by the pre-inspection camera fall in the $549-$699 range. Call (726) 600-7155 for a written price specific to your home – the estimate is free.
Is a $79 duct cleaning offer legit?
No San Antonio air duct cleaning job can be done correctly for $79. That price point is typically a loss-leader that gets a technician into your home, at which point high-pressure upselling begins – often for services the homeowner can’t verify are needed. A legitimate duct cleaning job using professional-grade negative-pressure equipment, with before-and-after documentation, in a typical San Antonio home, costs a minimum of $299 and often more. The $79 visit is priced to get in the door, not to clean the ducts.
How often should San Antonio homeowners clean their air ducts?
Every 3-5 years is the baseline for most San Antonio homes with no unusual contributing factors. Homes with pets shed dander into the duct system year-round; San Antonio’s extended warm season means HVAC systems run longer annual cycles than homes in northern markets, pulling more air (and particulate) through the duct walls. Homes with occupants who have respiratory sensitivities, homes that have had recent renovation work, or homes where the filter maintenance has been inconsistent may warrant cleaning closer to the 3-year mark. The camera inspection tells you more than any calendar estimate.
Does duct cleaning actually improve air quality or HVAC efficiency?
The documented evidence supports it for contaminated systems. NADCA research shows that a duct system with significant particulate build-up on duct walls restricts airflow and forces the air handler to work harder to move the same volume of conditioned air – which affects both runtime efficiency and system wear. The air quality benefit is more direct: a system with visible debris at registers is distributing that debris into the living space with every cycle. Whether your system is at that threshold is exactly what the pre-inspection camera is for. CleanRun doesn’t quote a cleaning without showing the inspection result first.
What should be included in a professional duct cleaning at this price?
At the $299-$699 price range in San Antonio, a legitimate job should include: pre-inspection camera footage of every accessible duct run, negative-pressure extraction using professional-grade equipment (not a shop vac), mechanical agitation at each run, plenum cleaning, post-cleaning camera documentation, and a written price agreed to before work starts. If a company in San Antonio is quoting you a price without a pre-inspection, without named equipment, or without a written scope, that’s not the same service – regardless of what the invoice calls it. Call (726) 600-7155 to get CleanRun’s written price and see the comparison for yourself.
Can I get a same-day or next-day duct cleaning appointment in San Antonio?
CleanRun takes calls 24 hours a day, 7 days a week, with a live person on the line – not a recording. Same-day availability depends on the schedule at the time you call, but next-day appointments in San Antonio are typically available. The written price is delivered before the appointment is scheduled, not when the technician arrives.
Why CleanRun’s Pricing Works the Way It Does
The home of this business is San Antonio. CleanRun has been in local ductwork since 2013, with more than 52,000 homes served and a written price on every one of them. Tomas Reyes built the company on a simple operational premise: the customer should never find out what something costs after the work is done. That’s Haven Standard Clause 1, and it’s not a marketing line – it’s the reason we photograph the inspection before the quote, write the price before any panel comes off, and back the result with a 365-Day Done Right Promise that’s documented in writing on every job.
The equipment CleanRun uses – Rotobrush, Nikro, Abatement Technologies for air scrubbing, Honeywell and Aprilaire for filtration, Guardsman for duct sealing – is listed on this page because a customer who can look up those brand names independently is a customer who understands what’s being quoted. That’s the standard. The photo record the customer receives when the job is done is the proof that the standard was met.
