How Much Does Air Duct Cleaning Cost in San Antonio?
Air duct cleaning in San Antonio typically costs between $299 and $599 for a standard single-family home, with most jobs landing around $350 to $450 depending on home size and duct configuration. Most reputable companies - including Bellows Air Duct & Vent Co. - complete the work in a single visit and give you the price before anyone touches a vent.
If you’ve gotten a quote well below that range, read the fine print. San Antonio has no shortage of bait-price operators who advertise $49 whole-house specials and then add charges at the door for each vent, each register, each square foot. The number that follows is what an honest, camera-verified job actually costs in this market.
Air Duct Cleaning Cost Breakdown (2026)
Air duct cleaning in San Antonio is priced most honestly by whole-home job, not by the vent. Here’s what you can expect to pay across common home sizes and service types in the San Antonio area:
| Service | Typical San Antonio Price Range |
|---|---|
| Small home (under 1,500 sq ft, 1 system) | $249 – $329 |
| Mid-size home (1,500 – 2,500 sq ft, 1 system) | $329 – $449 |
| Larger home (2,500 – 3,500 sq ft, 2 systems) | $449 – $599 |
| Large home or estate (3,500+ sq ft, 2+ systems) | $599 – $849+ |
| Dryer vent cleaning (add-on or standalone) | $89 – $149 |
| Duct sanitizing / antimicrobial treatment | $75 – $150 added to base job |
| Duct repair or sealing (per section, if needed) | $150 – $400+ |
| Seasonal HVAC tune-up (add-on) | $89 flat (Bellows standing offer) |
A few things drive that range. San Antonio homes built in neighborhoods like Stone Oak, Alamo Ranch, and Helotes tend to be newer construction with flex duct systems that respond well to a single thorough clean. Older homes in Terrell Hills, King William, or Monte Vista often have rigid metal ductwork that’s been in place for decades – sometimes since the original build in the 1950s or 60s – and may carry significantly more accumulated debris. Attic-mounted air handlers, which are common in San Antonio because of how homes are built here for the heat, can also add access time and push a job toward the higher end of the range.
At Bellows, the price you hear on the phone is the price on the invoice. No surprises on the bill – that’s been the standard since we opened in 1984, and it hasn’t changed.
What Affects Air Duct Cleaning Pricing in San Antonio
- Home size and number of vents: Larger homes have more duct runs, more registers, and more surface area to clean. A 3,200-square-foot home in The Dominion with a two-system setup takes meaningfully longer than a 1,400-square-foot home in Lackland City with one central unit.
- Number of HVAC systems: San Antonio homes above 2,500 square feet often run two separate systems – one for the upstairs, one for the down. Each system means a separate air handler, a separate blower, and a separate set of duct runs. Plan for the price to reflect that.
- Duct material and configuration: Flexible insulated ductwork (the spiral-wrapped kind common in homes built after the late 1980s) cleans differently than older sheet metal. Rigid metal ducts in homes along Broadway or in Beacon Hill often have decades of debris layered in corners and elbows that require more time with a Rotobrush or Nikro system to address properly.
- San Antonio’s climate and dust load: The Bexar County area sits in a semi-arid zone that generates a high amount of fine particulate – caliche dust from construction in fast-growing areas like Far West Side and Converse, cedar and oak pollen from the Hill Country that backs up to the northwest, and the long cooling season (easily eight months of AC use) that keeps air cycling through ducts far more than in northern climates. Homes that haven’t been cleaned in seven or more years often carry heavier loads that extend job time.
- Accessibility of the air handler and ductwork: Attic-mounted units in San Antonio homes – extremely common here because slab foundations leave no basement to put equipment – mean a technician is working in a space that hits 130 degrees in July. That affects how the job is scoped. Crawl space or closet-mounted units are faster to access and may land at the lower end of the range.
- Add-on services: Antimicrobial fogging, dryer vent cleaning, and duct sealing are priced separately and are not bundled into the base air duct cleaning fee. Any company that claims all of those are included in a $99 whole-house price is either skipping steps or using a different math entirely. Ask what’s specifically included before you book.
How to Save on Air Duct Cleaning in San Antonio
Getting a fair price on duct cleaning isn’t about hunting for the lowest number – it’s about getting real work done the first time so you’re not calling someone back six months later. That said, there are a few straightforward ways to keep costs reasonable without cutting corners.
Bundle services in a single visit
If your dryer vent is also due for cleaning – and in San Antonio, the Bexar County Fire Marshal’s office recommends annual dryer vent checks given the high dryer usage year-round – scheduling it alongside your duct cleaning usually costs less than two separate trips. Same goes for an HVAC seasonal tune-up. Bellows offers a flat $89 seasonal tune-up that pairs well with a duct cleaning visit, saving you a second scheduling call and a second service fee.
Ask about standing discounts before booking
Bellows extends a permanent 5% discount to seniors and veterans – no coupon needed, no expiration. If you’re a veteran in San Antonio, that discount applies every time, on every job. It’s a small number in dollar terms but it’s reliable, and it’s there whether you mention it on the phone or at the door.
Get a second opinion on any written estimate
If another company has handed you a written estimate that looks higher than expected, Bellows will review it at no charge. A free second opinion on any written estimate is a standing offer – call (844) 685-6342 and bring the paperwork. Sometimes the original estimate is fair. Sometimes there are line items that don’t belong. Either way, you’ll know before you commit.
Don’t chase the lowest coupon
The $49 and $79 whole-house specials that appear in San Antonio newspaper inserts and on door hangers in neighborhoods like Shavano Park and Helotes are almost never what they appear to be. The business model requires upselling at the door – extra charges per vent, per return, per pound of debris, per whatever the technician decides to find. A job quoted at $79 routinely ends at $400 or more, but without the camera verification, the upfront pricing, or the guarantee that a reputable company provides. The math rarely favors the coupon.
Keep up with regular maintenance
Homes cleaned on a reasonable schedule – every three to five years for most San Antonio households, more frequently if you have pets, allergy sufferers, or recent construction nearby – don’t accumulate the kind of debris loads that make jobs longer and costlier. A well-maintained duct system cleans faster, which keeps pricing at the lower end of the range.
For a free estimate with no obligation, call (844) 685-6342. The price you get on the phone is the price before we start – and the home of that promise has been Bellows since 1984.
FAQs – Air Duct Cleaning Cost in San Antonio
How much does air duct cleaning cost in San Antonio in 2026?
Most San Antonio homeowners pay between $299 and $599 for a full duct cleaning, with the average single-family home coming in around $350 to $449. Smaller homes under 1,500 square feet often fall below $330. Larger homes with two HVAC systems – common in San Antonio subdivisions like Sonterra and Rogers Ranch – can reach $600 or more. Call (844) 685-6342 for a free estimate specific to your home’s size and configuration.
Why is one company quoting $79 and another quoting $399?
The $79 quote is almost certainly a per-vent or bait-and-switch model. A typical San Antonio home has 15 to 25 vents and registers. Companies using that pricing structure routinely charge $15 to $35 per vent at the door, which adds up to $300 to $600 or more before any actual duct work is included. The $399 quote from a reputable company is likely a flat, whole-home price that covers everything before work starts. Always ask whether the quote is per-vent or whole-home, and get it confirmed before anyone arrives. Bellows quotes whole-home, upfront – no changes at the door.
How often should San Antonio homes have their ducts cleaned?
Every three to five years is a reasonable baseline for most San Antonio households. Homes near construction zones in fast-growing corridors like the Far West Side, Converse, or Cibolo may benefit from cleaning every two to three years due to elevated caliche and construction dust. Homes with pets, smokers, or residents with respiratory sensitivities should also lean toward the shorter interval. In San Antonio, the eight-month cooling season means your system runs – and recirculates air through those ducts – far longer than in most U.S. cities.
Is it worth paying more for camera inspection?
Yes – and here’s a concrete reason. A camera inspection before cleaning shows what’s actually in the ductwork, which affects how the job is scoped and priced. A camera inspection after cleaning gives you visual proof that the debris is gone, not just the technician’s word for it. Without before-and-after documentation, you have no way to verify the work was done. Bellows includes camera inspection on every job as a standard step, not an upsell – it’s how we back the 90-Day Done Right Promise with something more than a handshake.
Does Bellows offer any discounts on air duct cleaning?
Bellows extends a permanent 5% discount to seniors and veterans on any service. There’s also $50 off any repair over $250, a flat $89 seasonal tune-up, and a free second opinion on any written estimate from another company. These are standing offers with no coupon code required and no expiration date. Call (844) 685-6342 to confirm current pricing and confirm which offers apply to your job before booking.
Can I get air duct cleaning and dryer vent cleaning done the same day?
Yes, and it’s the most efficient way to handle both. Bellows schedules dryer vent cleaning alongside air duct cleaning regularly – it keeps you from paying for two separate service calls and means one set of technicians handles both jobs in a single visit. Dryer vent cleaning runs $89 to $149 in the San Antonio market as an add-on. Given that clogged dryer vents are one of the leading causes of residential fires in Bexar County, it’s worth handling when technicians are already on site.
