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.

AfterHow Much Does Air Duct Cleaning Cost in San Antonio?
Air Duct Cleaning in San Antonio typically costs between $300 and $700 for a standard single-family home, with most jobs landing around $400 to $500 depending on system size, duct condition, and whether any add-on services are needed. That range assumes negative-pressure extraction with rotary brushing – the method that actually dislodges debris rather than just vacuuming near the registers. At CleanRun, every job comes with a written price before any panels come off, so the number you see on paper is the number on your invoice.
Air Duct Cleaning Cost Breakdown (2026)
If you’re looking for Air Duct Cleaning Near Me in San Antonio, TX, expect costs between $300 and $700 for a standard single-family home in 2026. The table below breaks down what each service line typically costs in this market – not a national average, but what CleanRun actually quotes on jobs across neighborhoods like Stone Oak, Alamo Heights, Helotes, and the Medical Center corridor.
| Service | Typical San Antonio Price Range (2026) |
|---|---|
| Standard duct cleaning (up to 10 supply/return vents) | $300 – $400 |
| Standard duct cleaning (11-20 vents) | $400 – $525 |
| Larger home / 21+ vents or multi-zone system | $525 – $700 |
| Dryer vent cleaning (add-on or standalone) | $89 – $149 |
| Sanitizing treatment (antimicrobial fogging post-clean) | $75 – $150 |
| Duct sealing / minor duct repair | $150 – $400 per section |
| HVAC coil and blower cleaning (combined with duct cleaning) | $125 – $250 (add-on) |
| Mold remediation in ductwork (treated area, not full system) | $300 – $600+ |
What Drives the Cost Up or Down
The single biggest variable is duct count and layout. A 2,000-square-foot ranch-style home in Converse with a straightforward single-zone system costs less to clean than a 2,400-square-foot two-story in Shavano Park where the upstairs zone routes through the attic and doubles back through interior walls. More duct runs mean more brushing passes, more time under negative pressure, and more photographs in the documented photo record.
Condition matters almost as much as count. San Antonio homes built between 1975 and 1995 – a large share of the housing stock in areas like Woodlake, Oak Hills, and Westover Hills – frequently have flex duct that was installed without adequate support. Over time those sections sag and trap debris at every low point. When the camera on our Rotobrush unit shows a 2-to-3-inch debris shelf at the first elbow off the plenum (the main distribution box connected to the air handler), that job takes longer and costs more than one where the ducts are clear.
Add-on services are almost always optional, though some are worth discussing before the crew leaves. Antimicrobial fogging after cleaning is one we recommend when the camera picks up visible biological growth – not as a default upsell. The written price covers every line before work starts, so there are no mid-job surprises.
What Affects Air Duct Cleaning Pricing in San Antonio
- Number of vents and duct runs: Most San Antonio homes have between 10 and 25 supply and return registers. Each run gets individually photographed and brushed under negative-pressure extraction, so a home with 22 runs takes measurably longer than one with 12. Larger systems cost more because the labor is proportionally greater – not because of an arbitrary per-vent fee structure.
- Duct material and age: Fiberglass board duct, rigid sheet metal, and flex duct each require different brush settings and different extraction pressures. Homes in Alamo Heights and King William built before 1965 often have sheet metal duct that is structurally sound but heavily contaminated with decades of accumulated dust and, occasionally, rodent debris from attic intrusion. Flex duct in homes from the 1980s and 1990s can be fragile at connection points, which requires slower brush speeds and adds time.
- Attic conditions: San Antonio summers push attic temperatures well above 130 degrees Fahrenheit from May through September. That heat accelerates the breakdown of duct insulation and, when combined with the city’s humidity swings during our spring storm season, creates conditions where condensation forms inside flex duct – a factor that directly contributes to microbial growth. Jobs where the technician has to work in a hot attic mid-summer carry a real labor cost that shows up in the quote.
- System accessibility: Crawlspace-mounted systems in older homes near Southtown and the near east side can require additional time to access and photograph properly. Homes with sealed soffits covering duct runs, or systems where the air handler is in a utility closet rather than the attic, also affect how long the job takes.
- Additional services requested: Dryer vent cleaning, HVAC coil cleaning, sanitizing, or duct repair are priced as separate line items in the written quote. Bundling two or more services on one visit typically reduces the total cost compared to scheduling them separately, since a portion of the job cost covers mobilization and setup.
- Degree of contamination: This one gets underreported by competitors who lead with $79 coupons. A system that has never been cleaned in 15 years – common in homes purchased during San Antonio’s 2020-2022 buying surge, where inspections were waived or rushed – will have substantially more debris than one last cleaned three years ago. Our camera shows what’s actually there. The quote reflects the actual work scope.
BeforeAfterThe $79 Coupon Problem in San Antonio
San Antonio homeowners searching for duct cleaning deals will run into a familiar pattern: a coupon advertised online for $49 to $79, a phone call from a company with a generic name, and a technician who arrives with a portable shop-vac and a longer list of things that “have to be added” once they’re in your home. The Texas Department of Licensing and Regulation fields complaints from this exact scenario regularly.
The way to read any duct cleaning quote is simple: ask what equipment will be used and ask to see the written price before scheduling. At CleanRun, the equipment is Rotobrush for rotary contact brushing and Nikro for negative-pressure extraction – both trade-recognized brands that homeowners can look up before agreeing to anything. Under Haven Standard Clause 1, a written price is delivered before any work starts, on every job, without exception. There is no “call for a quote” and no price revealed only after the technician is already in your attic.
The documented photo record – inside every duct run, before and after – is also a standard deliverable, not an upsell. If a company cannot show you the inside of your ducts before and after the work, you have no way to verify that anything was actually cleaned.
How to Save on Air Duct Cleaning in San Antonio
Bundle Services on One Visit
The most straightforward way to reduce your per-service cost is to schedule dryer vent cleaning, HVAC coil cleaning, or a sanitizing treatment on the same visit as your duct cleaning. Mobilization – getting the truck, equipment, and crew to your home – is a fixed cost regardless of how many services are performed. Spreading that fixed cost across two or three services on the same day is more efficient, and the savings show up in the written quote.
Time Your Service Strategically
In San Antonio, demand for HVAC-related services peaks in April through June as homeowners turn on air conditioning for the first time and discover airflow problems, and again in September when systems run hard through the last of the summer heat. Scheduling in January, February, or November typically means faster availability and, with some providers, reduced pricing. At CleanRun, pricing is the same year-round – but scheduling is easier in the shoulder months, which means you’re less likely to wait.
Get a Second Opinion on Any Written Quote
If you already have a written estimate from another company, CleanRun will put its own written number next to it at no cost. That’s not a conditional offer – it’s a standing policy. Bring the competing quote, and we put our price in writing next to theirs. You decide which one reflects fair market value for the actual scope of work described.
Check What’s Actually Included
Before comparing prices across companies, confirm what each quote covers. A $350 quote that includes rotary brushing, negative-pressure extraction of every duct run, a documented photo record, and a written warranty is a different product from a $350 quote that covers a blower vacuum at the main return and a visual check of a few registers. Ask specifically: how many duct runs are included, what equipment will be used by name, and what documentation will be delivered when the job is finished.
Don’t Over-Service
The EPA’s guidance and the National Air Duct Cleaners Association both suggest that duct cleaning is typically needed every three to five years in a well-maintained home, or sooner after renovation, water damage, rodent intrusion, or a significant occupant change (like moving into a home with a previous pet owner). In San Antonio’s dusty conditions – particularly in areas near Loop 1604 construction corridors and the Medina Valley – every three to four years is a reasonable benchmark. Cleaning annually is generally unnecessary and adds cost without proportional benefit.

What the Camera Actually Shows: San Antonio-Specific Findings
We’ve been photographing the inside of duct systems across San Antonio since 2013, and a few patterns come up consistently enough to be worth naming.
In Stone Oak and the far North Side, homes built between 2000 and 2010 frequently have flex duct runs that were installed with too few hangers. The duct sags between supports, creating low points where condensation pools during the humid months of May and June. The camera shows a dark, damp debris layer at those sags – sometimes with visible biological growth – that a vacuum-only approach doesn’t reach. Rotary brushing under negative pressure is the method that actually dislodges it.
In the older neighborhoods east of US-281 – Terrell Hills, Mahncke Park, and the areas surrounding the Broadway Corridor – we regularly find original sheet metal duct from the 1960s and 1970s that is structurally intact but carrying 30-plus years of accumulated debris. These systems often haven’t been cleaned since the home was last sold, and the debris load at the plenum is typically substantial enough that the job takes 30 to 45 minutes longer than a comparable square-footage newer home.
In Helotes and Leon Valley, where homes often sit near open land and experience more particulate intrusion from soil disturbance during construction on adjacent lots, we find higher-than-average dust and dander loads in homes that were otherwise well-maintained. Families with respiratory sensitivities in those areas tend to notice the difference in air quality within a week of a proper cleaning.
None of this is guesswork. The camera shows what’s there. The written quote reflects what the job actually requires. If you’d like to understand what your own system looks like before agreeing to anything, that conversation starts with a call to (726) 600-7155.
What You Should Receive When the Job Is Done
A completed air duct cleaning job should leave you with more than a cleaner system. At CleanRun, every completed job includes three concrete deliverables:
- Documented Photo Record: Photographs of the inside of every duct run, taken before and after the cleaning. These are delivered to you as part of the standard job record – not stored only on our end. You can see what was there, and you can see what was removed.
- Written scope confirmation: A document listing every duct run cleaned, every add-on service performed, and any findings noted during the job (debris type, any duct damage observed, any areas inaccessible due to construction). This is the record you keep for your home file.
- 365-Day Done Right Promise: If the work isn’t right, we make it right. That’s in writing on the job record, not a policy subject to a manager’s interpretation. If something about the cleaning doesn’t hold up within 365 days of the service date, we come back and correct it.
These aren’t premium add-ons. They’re standard on every CleanRun job, regardless of price point – because documentation is the only way to verify that work was actually done.
How to Read a Competitor’s Duct Cleaning Quote
If you’re comparing CleanRun’s written estimate against quotes from other San Antonio duct cleaning companies, here’s what to look for line by line.
First, check whether the quote names the equipment. “Professional duct cleaning” is not a specification. Rotobrush, Nikro, and Abatement Technologies are specifications – equipment with known performance characteristics that you can verify independently. If a quote doesn’t name the tools, you don’t know what you’re buying.
Second, check whether the quote covers all duct runs or just the main trunk and a few registers. Some low-priced quotes cover only the accessible returns and leave the supply-side branch runs untouched. That’s not a Full System Cleaning – it’s a partial service priced like a full one.
Third, ask about documentation. What will you receive when the job is finished? A verbal description of what the technician saw is not documentation. A photograph of a dirty duct posted on a tablet screen during the visit is not documentation. A delivered photo record, indexed by duct run, is documentation.
Finally, ask whether the written price is the final price. Under Haven Standard Clause 1, CleanRun’s written price is the final price – period. If a competitor’s quote includes language like “additional charges may apply based on conditions found,” the final cost can be substantially higher than what was quoted on the phone.
FAQs – Air Duct Cleaning Cost in San Antonio
How much does air duct cleaning cost in San Antonio in 2026?
Air duct cleaning in San Antonio costs between $300 and $700 for most single-family homes in 2026, with the majority of jobs priced between $400 and $525. The range depends on duct count, system layout, duct condition, and whether add-on services like dryer vent cleaning or sanitizing are included. CleanRun delivers a written price for your specific home before any work starts – call (726) 600-7155 for a no-obligation written estimate.
Is it cheaper to clean ducts in winter in San Antonio?
Availability is typically better in January and February, which can mean faster scheduling and, with some providers, promotional pricing. At CleanRun, pricing is consistent year-round – but if getting on the schedule quickly matters to you, the winter months are the easiest time to book. That said, don’t wait until spring if your system has visible debris or airflow problems; those issues don’t improve on their own over a San Antonio winter.
What is a fair price to pay for air duct cleaning?
A fair price in the San Antonio market is $350 to $550 for a home with 12 to 20 vents, using professional-grade rotary brushing and negative-pressure extraction – not a shop-vac. Quotes below $150 for a full-system cleaning almost always involve either partial-only service, high-pressure upselling once the crew arrives, or both. Quotes above $700 for a standard single-family home should include a clear written explanation of what additional scope is driving the cost. Call (726) 600-7155 and we’ll put a written number next to any existing quote you have.
How often should air ducts be cleaned in San Antonio?
Every 3 to 5 years is the typical recommendation for a well-maintained San Antonio home. In practice, we recommend moving toward the 3-year end of that range for homes in higher-dust areas (near active construction corridors on Loop 1604 or Highway 151), homes with pets, homes with occupants who have respiratory sensitivities, and any home where the previous cleaning can’t be documented. After renovation work – especially drywall cutting or flooring removal – cleaning sooner makes sense regardless of when the last service was performed. Our home page has more detail on the full range of services that affect indoor air quality.
Why is one company quoting $79 and another quoting $450 for the same service?
The $79 quote and the $450 quote are almost never the same service. The $79 entry price typically covers a single return vent or a short vacuum pass at the main trunk – enough to get a crew into your home, where the real pricing conversation begins. The $450 quote that covers rotary brushing of every duct run, negative-pressure extraction, a documented photo record, and a written 365-day guarantee is a different scope of work entirely. The way to compare them accurately is to ask both companies to put the full scope in writing before any work starts. Call (726) 600-7155 and that’s exactly what you’ll receive from CleanRun – a written price for a specified scope, before anyone touches your system.
Does air duct cleaning actually make a difference in San Antonio homes?
Yes – when it’s done with the right equipment and documented properly. In San Antonio’s climate, where air handlers run for 8 to 10 months of the year and attic temperatures accelerate duct material breakdown, debris accumulates faster than in cooler markets. The camera on a Rotobrush unit shows what’s actually inside the duct runs. In homes that haven’t been cleaned in 10 or more years – a common scenario in properties purchased during the 2020-2022 buying surge – the before-and-after photographs tell the story more clearly than any description. Homeowners with dust sensitivity or allergy symptoms frequently report a noticeable difference within the first few days after a proper cleaning. The operative word is “proper” – negative-pressure extraction with rotary contact brushing, not a portable vacuum held near an open register.
