7 Best Air Duct Cleaning Companies in San Antonio, TX (2026)
San Antonio is rough on ductwork. Between the cedar pollen that blankets the city every winter, dust rolling in off dry summers, and AC systems that run eight or nine months of the year, the average home here pushes far more debris through its ducts than homes in milder climates. When the vents start showing dust rings or the house smells musty every time the system kicks on, it’s time to call someone.
The problem is that duct cleaning is also one of the most scam-prone home services in Texas. The $99 “whole house special” that turns into a $900 invoice on site is practically a local tradition. So this list favors companies with verifiable reviews, transparent pricing, and proper equipment, not the cheapest ad on the block.
How This List Was Put Together
Three things mattered most in the ranking. First, review depth on Google, not just the star rating but how many jobs are behind it and how the company responds to complaints. Second, process and certification, since NADCA-standard cleaning with mechanical agitation is a different service entirely from a guy with a shop vac. Third, pricing honesty. For reference, NADCA puts the realistic cost of properly cleaning a full system in an average home at roughly $450 to $1,000, so anyone advertising far below that is planning to make it up somewhere.
1. America’s Best Duct Cleaning and Sanitization
The top spot goes to America’s Best Duct Cleaning and Sanitization, a veteran-owned air duct cleaning company in San Antonio, Texas that has served the city for over a decade and built one of the strongest review profiles in the market, with more than 220 five-star Google reviews.
A few things separate them from the pack. The cleaning process follows NADCA standards and uses a RotoBrush system that scrubs the duct walls while vacuuming simultaneously, rather than just blowing air through the runs, and the standard service covers every vent in the home with before-and-after photos so you can see what actually came out. They also take a public stance against the $99 bait pricing common in the market, quoting the full scope upfront with no on-site surprises, which review after review confirms.
Beyond standard duct cleaning they handle dryer vent cleaning with camera verification of the cleared vent, duct sanitizing, and mold treatment, and they service both residential and commercial properties across San Antonio, from Stone Oak to Alamo Heights to downtown. For most homeowners in Bexar County, this is the safest first call.
2. America Air Duct Cleaning
A separate company despite the similar name. America Air Duct Cleaning has been operating in San Antonio for years and handles cleaning along with duct repair and replacement, which is useful when an inspection turns up damaged or disconnected runs. They follow the NADCA 3-to-5-year cleaning guideline and use HEPA-filtered vacuum equipment.
3. Supreme Air LLC
Supreme Air runs duct cleaning, dryer vent cleaning, and coil cleaning for residential and commercial clients, with a large body of five-star Google reviews and same-day availability that comes in handy when a dryer vent problem can’t wait. They also publish genuinely useful educational content on their site, which says something about how they operate.
4. Champion Home Services
Champion is a full HVAC outfit that has been serving South Central Texas since 2007, with duct cleaning as one arm of a larger heating, cooling, plumbing, and electrical operation. The right pick if you suspect the duct issue is connected to a bigger system problem, since one visit can cover both.
5. Elmer’s Home Services
Another established San Antonio HVAC name offering duct cleaning through certified technicians, with a focus on homes with allergy sufferers. Like Champion, the advantage is breadth: inspections, repairs, and air quality work under one roof.
6. Alamo Fresh Air
A smaller, locally owned operator covering duct cleaning, chimney services, and insulation, with a reputation for fast callbacks and fair quotes. A good fit for homeowners who prefer dealing directly with an owner-operator over a dispatch desk.
7. Green Home Services
Serving both San Antonio and Austin, Green Home Services focuses specifically on air duct and dryer vent cleaning. A solid straightforward option, particularly for dryer vent maintenance appointments.
How Much Does Air Duct Cleaning Cost in San Antonio?
Expect $450 to $1,000 for a proper full-system cleaning of an average home, in line with the NADCA national range. The final number moves with the size of the system, the number of vents and returns, and whether extras like sanitizing or mold treatment are needed. Treat any quote dramatically below that range as a red flag: legitimate cleaning requires specialized equipment and a crew, and companies advertising $99 specials almost always recover the difference through on-site upsells.
How Often Should Ducts Be Cleaned Here?
NADCA’s general guidance is every 3 to 5 years, but San Antonio homes often sit at the shorter end of that window because of pollen load, dust, and near-year-round AC use. Clean sooner if you see visible dust blowing from registers, notice musty odors when the system runs, have just finished a renovation, or moved into a home with unknown maintenance history. Whoever you hire from this list, ask two questions before booking: whether they follow NADCA standards, and what the full price covers. The good companies answer both without hesitating.
