And if you’re still sizing up options, start with our guide to Air Duct Cleaning in San Antonio for the full local breakdown.
Fast, Local Air Duct Cleaning
Speed matters when your vents are blowing dust onto every surface, or when a musty smell kicks on with the AC. We get that. That’s why we built our scheduling around same-day and next-day availability across San Antonio. Call before noon on a weekday and there’s a strong chance we can have a technician at your door that afternoon. Evening and weekend calls get priority slots the following morning.
What you won’t get is a four-hour arrival window or a technician who calls 20 minutes before they show up. Every booking through Cardinal Air Duct San Antonio comes with The Relay Standard: a live trackable arrival time you can follow from your phone, before-and-after photo proof of the work, and a digital invoice you can pay from a link. No paper, no guesswork, no waiting around wondering where the truck is. This is how home service should work, and we’ve been doing it this way since Relay Home Co. launched in 2005.
Our response time across San Antonio proper, as well as New Braunfels, Cibolo, Converse, Terrell Hills, Timberwood Park, Floresville, and Scenic Oaks, is typically same-day or next-day. Emergency after-hours calls are answered by a live person, always. No answering service scripts. No “we’ll call you back Monday.” You call, a human picks up, and we get you on the schedule.
How Much Does Air Duct Cleaning Cost in San Antonio?
Here’s the honest pricing breakdown most companies won’t hand you until after they’re inside your home. We write it down before any work starts, and that number does not change at the door. No bait-and-switch. No “you have mold” upsell scare tactics. Just straight numbers.
San Antonio Air Duct Cleaning Price Ranges
- Small home or apartment (under 1,200 sq ft, up to 8 vents): $299 – $399
- Standard single-family home (1,200 – 2,500 sq ft, 9 – 14 vents): $350 – $550
- Larger home (2,500 – 3,500 sq ft, 15 – 20 vents): $500 – $750
- Multi-story or custom home (3,500+ sq ft, 20+ vents): $700 – $1,000+
- Add-on: dryer vent cleaning: $75 – $150
- Add-on: HVAC evaporator coil cleaning: $150 – $300
These ranges reflect what we see across Bexar County and the surrounding areas in 2025 and 2026. Homes in older neighborhoods like Monte Vista or Alamo Heights often have decades-old galvanized ducts that take longer to clean properly. Newer builds in places like Cibolo or Timberwood Park tend to have flex duct that moves faster. Either way, you’ll get a written price before we touch a single vent.

What’s Actually Included in Our Air Duct Cleaning?
We don’t do “shop-vac specials.” Hooking a basic vacuum to your register and calling it a day is how some cheap outfits operate, and it leaves the worst debris sitting deep in your trunk lines. We deliver a Full System Cleaning every time.
Here’s what a standard Cardinal Air Duct San Antonio cleaning includes:
- Full supply and return duct cleaning using a Rotobrush rotary brush system that physically agitates caked-on dust, pet hair, and debris off duct walls.
- Negative-pressure extraction with a Nikro HEPA-rated vacuum. That means the loosened debris goes straight into the vacuum, not back into your living room. HEPA filtration captures particles down to 0.3 microns, so what leaves the duct never re-enters your air.
- Containment setup using Abatement Technologies equipment when needed, especially on heavily contaminated systems or homes with mold remediation history.
- Register and grille cleaning on every vent, supply and return.
- Plenum and trunk line inspection with photo documentation so you see exactly what was inside and what it looked like after.
- Optional filtration upgrades including Honeywell media filters, Aprilaire whole-home air purifiers, and Guardsman antimicrobial treatments.
The full process on a typical 2,000-square-foot San Antonio home takes about 2 to 3 hours. You’ll get before-and-after photos of the inside of your ducts, not just a tech saying “all done.” That’s the Relay Standard. Visibility from start to finish.
Areas We Cover
Cardinal Air Duct San Antonio covers everywhere from downtown high-rises to Hill Country cul-de-sacs. We’re on the road every day across Bexar County and into the surrounding counties. If you’re in San Antonio proper, New Braunfels, Cibolo, Converse, Terrell Hills, Timberwood Park, Floresville, or Scenic Oaks, you’re in our regular service area and we can usually reach you same-day.
Not sure if we cover your specific neighborhood? Call (254) 347-3897. If you’re within about 45 minutes of downtown San Antonio, the answer is almost certainly yes. We also handle commercial duct cleaning for offices, medical spaces, and retail throughout the metro. You can learn more about our local service footprint on our home page.
When Should You Actually Get Your Ducts Cleaned?
Not every home needs annual duct cleaning. Here’s what we actually tell our San Antonio customers, because an honest answer builds more trust than a subscription plan.
You should consider duct cleaning if:
- You’ve lived in the home 3+ years and have never had the ducts cleaned.
- You have pets that shed, especially multiple dogs or cats.
- You renovated recently. Drywall dust and construction debris in ducts is extremely common after remodels, and San Antonio’s renovation boom means we see a lot of this in neighborhoods like Terrell Hills and Alamo Heights.
- Visible dust accumulates on furniture within 2 – 3 days of cleaning surfaces.
- Someone in the home has allergies or asthma, especially during cedar fever season when indoor air quality becomes critical.
- You smell something musty or stale every time the air kicks on.
- You just bought the home and don’t know the ductwork history. Previous owners’ pet dander, cigarette residue, or renovation dust is now yours.
If none of those apply, we’ll tell you to save your money. Seriously. We’ve talked plenty of San Antonio homeowners out of work they didn’t need, because the 365-Day Done Right Promise means we stand behind every job, and we don’t take jobs we can’t stand behind.
What Sets Cardinal Apart From Other San Antonio Duct Cleaners
There are companies in San Antonio that’ll quote you $99 and then “find” $800 in problems once the truck is parked in your driveway. There are franchise operations that send a different tech every time, none of whom know your home’s history. We’re neither.
Here’s what you get with Cardinal Air Duct San Antonio:
- Written price before any work starts. Not an estimate range. Not a “we’ll see once we get in there.” A written number, on paper or in your email, before a single duct is touched. And it does not change at the door. Ever.
- The 365-Day Done Right Promise. Every job is backed for a full year. If the work isn’t right within 365 days, we return and correct it at no charge. Not pro-rated. Not “subject to review.” We come back, we fix it, you pay nothing. This is the longest-standing satisfaction window we know of in the trade, and it covers every booking without exception.
- Background-checked, uniformed technicians. You’ll know your technician’s name before they open the door, and they’ll arrive in a clean Cardinal uniform with professional equipment, not a rented van and a wet-dry vac.
- A live person answers 24/7. No voicemail loops. No phone tag. No “leave a message and we’ll call you back next business day.” Call at 2 a.m. and a human answers. That’s the standard.
- Professional-grade equipment only. Rotobrush rotary brush systems. Nikro HEPA vacuums. Abatement Technologies containment units. These are the brands commercial HVAC contractors use, not the handheld gadgets sold at hardware stores.
- Before-and-after photo proof. You’ll see what the inside of your ducts looked like before we started and what they look like when we finish. No mystery, no trust-me.
Omar Haddad, our owner, set this standard when he brought Cardinal into the Relay Home Co. family. It’s how he’d want his own home treated, and it’s the only way we work.
Why San Antonio Homes Need More Frequent Duct Cleaning
San Antonio’s climate does a number on HVAC systems and the ductwork attached to them. Here’s the local reality we see on job sites every week:
- Humidity breeds biological growth. San Antonio’s summer humidity regularly hits 70 – 90%. Inside ductwork, especially older uninsulated metal ducts, condensation forms and creates exactly the dark, damp environment where mold and mildew thrive. We see this most often in older homes around Monte Vista, Jefferson, and Beacon Hill where original ductwork is still in place.
- Cedar fever puts indoor air quality under a microscope. Mountain cedar pollen season runs December through February, and San Antonio sits right in the blast zone. If your ducts are already carrying dust and debris, the added pollen load makes indoor air measurably worse. Homes in the Hill Country-facing areas like Timberwood Park, Scenic Oaks, and Stone Oak get hit first and hardest.
- New construction leaves dust behind. Cibolo, Converse, and the exploding growth corridors along I-10 and 1604 are full of recently built homes. Builders don’t clean ducts after construction. Drywall dust, sawdust, and insulation fibers sit in the flex duct until the system kicks on and blows it all through the house. We clean a lot of 1- to 3-year-old homes whose owners couldn’t figure out why the house never felt clean, and this is exactly why.
- Pets live indoors. San Antonio’s a dog town. Labs, German Shepherds, and increasingly doodles of every kind. Pet dander and hair cycle through the HVAC system constantly. Multi-pet homes need duct cleaning more frequently, full stop.
How the Process Works, Step by Step
You’ll know exactly what to expect from the moment you call. Here’s the full flow:
- Call (254) 347-3897. You talk to a live person. That person asks about your home’s square footage, approximate vent count, and any specific concerns. The call takes about three minutes.
- Get your written price. We send a written quote to your phone or email before the appointment. That number is final. If we arrive and the job is bigger than quoted, we discuss it with you before any work changes. The original number stands unless you approve a change in writing.
- Track your technician. The day of your appointment, you get a live arrival window you can track from your phone. No four-hour ranges. You’ll see exactly when the van is headed your way.
- The cleaning. Your technician arrives in uniform, introduces themselves by name, lays down protective floor covering, and walks you through what they’ll be doing. Then they get to work with the Rotobrush system and Nikro HEPA vacuum.
- Photo proof. Before-and-after photos of the inside of your ducts are shown to you on-site and sent to your phone.
- Payment. You pay from a digital invoice link on your phone. Receipt is instant. The 365-Day Done Right Promise is active from that moment.
That’s it. No surprises, no pressure, no mystery charges. This is how it’s supposed to work, and it’s how we’ve done it since the Relay Home Co. family got started in 2005.
