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.
The Cardinal Air Duct San Antonio Guarantee
When we clean ducts in San Antonio, we’re working inside walls you can’t see and airflow you can’t watch. That’s why our guarantee isn’t a handshake. It’s a written, 365-day commitment that covers the entire job, not just the parts we think might fail. If the work isn’t right within a full year, we return and correct it at no charge. No prorating, no fine print about which services qualify. Every booking gets the same terms. That’s the 365-Day Done Right Promise, and it’s the reason we hand you a written price before a single duct is touched, then back the finished work with the longest satisfaction window in the trade.
What’s Covered
- Workmanship on every service. Air duct cleaning, HVAC cleaning, and dryer vent cleaning each carry the full 365-day guarantee. If something we did doesn’t hold up, we’re back to fix it.
- Written pricing before work starts. The price you approve is the price you pay. No surprise add-ons when the tech is already at your San Antonio home.
- Before-and-after photo proof. You’ll see your own ducts, not a stock photo. We document what the Rotobrush loosened and what the Nikro HEPA unit extracted, so you can verify the work yourself.
- Background-checked, uniformed technicians. You’ll know the tech’s name before they ring your doorbell. They arrive in uniform, driving a marked vehicle, carrying professional-grade equipment.
- Professional equipment on every job. Rotobrush rotary brush systems, Nikro HEPA-rated negative-pressure vacuums, and Abatement Technologies containment units. Not a truck-mounted shop vac.
- Cleanup included. We treat your San Antonio home like we live next door. Drop cloths go down, access points get sealed, and we leave the space the way we found it.
- Live answers when you call. A real person picks up around the clock. No voicemail loops, no “we’ll get back to you next business day.”

Our Satisfaction Promise
If something isn’t right, you call us. A live person answers, you describe the issue, and we schedule the return visit. There’s no customer service maze, no re-diagnosis fee, no argument about whether the problem falls within some narrow definition of covered work. The 365-Day Done Right Promise means exactly what it says: if the work isn’t right within 365 days, we return and correct it at no charge. And if we perform a repair and that repair fails within the year, you get a free second visit to make it right. Omar Haddad, Owner at Cardinal Air Duct San Antonio, handles every guarantee claim the same way he’d want his own home handled: quick, direct, and resolved without a fight. Most guarantee issues come down to airflow that still feels weak, a vent that wasn’t fully sealed, or debris we missed around the return. When that happens, we don’t quote policy at you. We come back, inspect the work against the photos we took, and fix what needs fixing.
Licensed & Insured Backing
Paper promises only mean something if the company behind them can be held accountable. Cardinal Air Duct San Antonio is licensed and insured to operate in Texas, which means you’re not relying on goodwill alone. Our insurance covers the unlikely: property damage, worker injury, anything that goes sideways while we’re in your home. Licensing means we’re subject to state requirements for the work we perform. When you combine that with a written price before work starts, the 365-Day Done Right Promise, and a parent company in Relay Home Co. that has stood behind home service work since 2005, the guarantee isn’t just words on a website. It’s documented accountability, backed by people who answer the phone. That’s the real warranty behind every San Antonio job we do.

Here’s the process when something goes wrong, step by step, so you know exactly what to expect from Cardinal Air Duct San Antonio:
- You call (254) 347-3897. A live person answers, day or night. You tell them what’s wrong and they pull up your job file, including the before-and-after photos from your service.
- We compare your issue to the recorded work. The photos we took at your San Antonio home become the reference point. If debris is back, if airflow declined, if a seal failed, the photos tell us what happened.
- We schedule the return visit. No waiting for a manager callback. The person on the phone can book the correction, and you’ll get a live trackable arrival window through the relay standard booking system.
- The tech arrives, fixes it, and re-documents. We don’t just re-clean and leave. We take new photos, show you the comparison, and confirm the issue is resolved before we pack up.
- You get a digital invoice with everything documented. Payable by link, with the guarantee terms restated so there’s never a question about what was covered.
What the Guarantee Means for San Antonio Homes
San Antonio’s climate creates specific duct problems: dust from summer droughts, humidity that encourages microbial growth in dark duct runs, and pollen that blows in from the Hill Country during spring. A guarantee means more here than in drier or cooler markets because the conditions that dirty your ducts come back faster. When we clean a home in Alamo Heights, Stone Oak, or Helotes, we know the HVAC system will face another San Antonio summer within months. If the work doesn’t hold up through that seasonal cycle, the 365-Day Done Right Promise covers it. That’s the practical value of a full-year window in this city: it gives your system a full cycle of San Antonio air to prove the work was done right.
What to Know Before You Book
Three things set our guarantee apart from what you’ll hear from other duct cleaning companies in San Antonio. First, it’s written, not verbal. You receive the promise terms before we start. Second, it covers the entire year, not a 30-day or 90-day window that expires before your ducts realistically show signs of a bad cleaning. Third, it’s backed by a parent company that has operated since 2005 and holds every independently owned location to the same standard. The Relay Visibility Guarantee gives you a live trackable arrival time, before-and-after photo documentation, and a digital invoice you can pay from your phone. That’s not marketing language. That’s the operating standard Omar Haddad runs every San Antonio job against.
Frequently Asked Questions

Before-and-after photo proof is standard on every job. We show you photos of your actual ductwork, return, and vents before cleaning begins, then again after the Rotobrush loosened debris and the Nikro HEPA unit extracted it. You’ll see what came out of your own system, not a stock image. If you don’t see a difference, the guarantee applies.
Because this one is written, backed by a parent company operating since 2005, and enforced by a local owner who answers the phone. Omar Haddad runs Cardinal Air Duct San Antonio with the understanding that a guarantee is only as good as the person honoring it. That’s why every job includes a written price before work starts and written terms for the 365-Day Done Right Promise. Call (254) 347-3897 and a live person will walk you through it.
