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.

AfterFast, Reliable Air Duct Cleaning Across San Antonio
Air duct cleaning in San Antonio typically costs between $450 and $850 for a complete residential system, done as one flat price per system rather than a per-vent charge that creeps upward. We serve every part of San Antonio, from the neighborhoods off Curley Road to the newer developments near Mirada Boulevard and the homes clustered around the 33576 zip code. Scheduling is coordinated through our South Florida dispatch office, but the crew that arrives at your door is local, uniformed, and background-checked. Call (737) 727-2314 and you’ll talk to a live person who can walk you through what your San Antonio home actually needs.
Why Cardinal Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
San Antonio homeowners tell us the same thing over and over: they booked a duct cleaning once before and never knew whether the work was actually performed. That’s why every job we run in San Antonio comes with before-and-after photographs of your own ductwork – not stock images, not a glossy brochure, but camera stills from inside your supply and return lines. You see the mat of pollen and lint that was there, and you see it gone. Omar Haddad set the standard for this company: no guessing, no vague reassurances, just photo proof attached to your digital invoice.
We run professional equipment on every San Antonio job. Rotobrush rotary agitation tools break debris loose from duct walls while Nikro HEPA-filtered negative pressure pulls it out of the home instead of recirculating it. The work is backed by our 365-Day Done Right Promise: if it’s not right within a full year, we come back and correct it at no charge. That’s not a limited-time offer. It applies to every single booking, without exception.
When you book, you get The Relay Standard: a live trackable arrival window, the technician’s name before they ring the bell, and a written price handed to you before any tool comes off the truck. Omar Haddad built this business on the idea that homeowners should never have to chase a contractor for answers.
Air Duct Inspection in San Antonio
Air duct inspection in San Antonio is the first step we recommend before any cleaning is scheduled, and we include a camera walkthrough as part of every full system cleaning we perform. A proper inspection means feeding a video scope through your supply and return ducts to document what’s actually inside: pollen film from the live oak and cedar that blanket this part of Pasco County each spring, construction dust in newer homes along the 33576 corridor, or the kind of lint and hair buildup that accumulates in any household with pets and kids. You should see the footage yourself, on the spot. If the ducts are clean and you don’t need service, we’ll tell you that plainly and hand you the evidence. An inspection-only visit in San Antonio runs $149 to $249 depending on system size and access.
Camera Verification of Source Removal
We don’t ask you to take our word for anything. After cleaning, we run the camera again through the same lines we showed you before. The comparison is yours to keep.
Written Findings With Every Inspection
Our tech documents what the camera shows in a written summary, including any sections of the system that warrant attention: damaged flex duct, disconnected branch lines, moisture staining, or evidence of rodent activity. You get the report, not a sales pitch.
Residential Air Duct Cleaning in San Antonio
Residential air duct cleaning in San Antonio is the service this page is really about: whole-home cleaning of the supply and return ductwork that moves conditioned air through your house. A standard single-system home in San Antonio runs between $450 and $850. That’s one flat price for the entire duct system, agreed in writing before we start, no matter how many registers the home has. If you live in a larger two-story home off Curley Road or a custom build near Mirada Boulevard, we quote by system configuration, not by vent count.
What the Process Looks Like
Our tech starts by sealing off register openings and setting up negative pressure with a HEPA-filtered vacuum. Then Rotobrush agitation tools work through each branch line, loosening the sticky pollen film and dust that clings to duct walls. Loose debris flows straight into the vacuum containment unit, not back into your living room. When the last line is finished, we run the camera again and hand you before-and-after photos of your own ducts.
Full System Cleaning, Not Spot Cleaning
We clean the entire system: supply ducts, return ducts, the trunk lines, and the plenum boxes. A return duct cleaning alone, for instance, misses the supply side where most airborne dust actually travels. The flat price covers the whole system. No line-item surprise at the end.
Trusted Brands We Service in San Antonio
We work alongside the equipment brands San Antonio homeowners already have in their homes. Our techs are familiar with Honeywell filtration media replacements and Aprilaire whole-home air cleaner maintenance, and we use Abatement Technologies containment units on every job where debris control matters. We stock common filter sizes and replacement parts for these systems on the truck, so when a cleaning reveals a plugged filter housing or a torn media pad, we often fix it on the spot rather than scheduling a second visit. That fast turnaround matters in San Antonio, where a pollen-heavy spring can clog filtration components in a matter of weeks. Our Air Duct Cleaning team trains on these specific brands so the service call doesn’t become a compatibility guessing game.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Sticky oak and cedar pollen film. San Antonio sits close to Hill Country-adjacent tree cover, and spring pollen loads here don’t just blow around – they cake onto duct walls and blower compartments. A dry dusting won’t remove it; agitation and HEPA extraction are necessary.
- Per-vent pricing games from other companies. We regularly hear from San Antonio homeowners who were quoted $29 per vent and ended up with a $700 bill once every register in a two-story home was counted. We quote one flat price per system, written down before work starts.
- Attic ductwork in older homes. Many houses off Curley Road and surrounding streets have flex duct runs in unconditioned attics, and Florida humidity plus organic debris can lead to microbial film inside the lines. A camera inspection shows whether that’s active growth or simple dust accumulation.
- No proof the work happened. Too many cleaners in San Antonio finish the job and hand over an invoice with nothing to show. Homeowners can’t verify anything. Our before-and-after photographs of your own duct interiors change that entirely.
Pricing for Air Duct Cleaning in San Antonio, FL

FAQs About Air Duct Cleaning in San Antonio
Every 3 to 5 years is realistic for most San Antonio homes. Homes along tree-lined streets with heavy live oak and cedar pollen loads may benefit from a camera inspection every 2 to 3 years to check whether sticky film is building up. If you have pets that shed heavily, recent renovation work, or someone in the home with respiratory sensitivities, that timeline may move up. Call (737) 727-2314 and we’ll help you decide whether your ducts need service now or can wait another year.
One flat price for the whole system, always. We quote a written per-system price before any work begins, typically $450 to $850 for a standard single-system San Antonio home. Per-vent pricing is how other companies turn a $199 teaser into a $700 invoice. We don’t do that.
Yes. Every job includes camera footage from inside your supply and return ducts before we start and after we finish. You’ll get those images attached to your digital invoice so you can verify the source removal actually happened. Call (737) 727-2314 and ask us to walk you through a sample before-and-after set from another San Antonio home.
We run Rotobrush rotary agitation tools, Nikro HEPA-filtered negative pressure vacuums, and Abatement Technologies containment units on San Antonio jobs. That combination means debris is loosened mechanically and extracted under negative pressure straight into the vacuum, not blown back into your living space. This equipment matters specifically for the sticky pollen loads common in this part of Pasco County.
Scheduling depends on the day’s route and crew availability. We don’t promise same-day service because we won’t rush a job or overbook a crew to hit a marketing claim. Call (737) 727-2314 and a live person will give you the next available window in San Antonio, typically within a few days.
