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.

Why Cardinal Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
Omar Haddad leads our San Antonio crew, and the standard he set is simple: no per-vent pricing, no bait-and-switch quotes, and no work that can’t be verified with photographs. We’re independently owned and operated, held to The Relay Visibility Guarantee, which means every booking includes a live arrival window you can track from your phone, photo documentation of the work, and a digital invoice payable by link. That’s not a premium add-on. It’s how every job runs.
San Antonio homeowners call us because the price we hand over before touching a duct is the price on the invoice. Most standard cleanings in this market run $450 – $750 for a single-system home. Larger two-story builds or homes with long single-story runs near Stone Oak or Alamo Ranch can push toward $900. We’ll tell you the number before we start, not after we’ve counted registers.
Every job carries our 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That covers every booking, not select ones. And every repair includes a written guarantee plus a free second visit if the repair fails. No fine print on that. It’s just how we operate.
Commercial Air Duct Cleaning in San Antonio
Commercial Air Duct Cleaning in San Antonio is a different animal from residential work, and the systems we see in Medical Center office buildings, Broadway corridor storefronts, and industrial spaces along I-35 all have their own quirks. Rooftop units, long main trunk lines, multiple returns, and higher static pressure mean the cleaning has to be planned around the building’s operating hours, not just the equipment.
Office and Retail Systems
A commercial job starts with a video inspection of the supply and return network. We map the runs, identify access points, and give you a written flat price per system before any equipment comes off the truck. Nikro HEPA vacuums and Rotobrush agitation tools handle the heavy soiling in commercial ductwork without spreading dust into occupied spaces.
Restaurant and Medical Builds
Kitchen exhaust runs and clinic HVAC systems need containment. Abatement Technologies equipment seals off the work area, so debris moves straight into the HEPA filtration, not into dining rooms or exam rooms. We schedule around your hours, and the before-and-after photo set covers every accessible trunk line, not just a single register shot.
Air Duct Cleaning Services in San Antonio
Air Duct Cleaning Services in San Antonio run from full system cleanings to targeted supply or return duct work, and the job starts the same way every time: a camera inspection. We don’t guess at what’s inside your ducts. We look. Then we quote one flat price for the system.
Full System Cleaning
This covers the supply ducts, return ducts, air handler, blower motor, and registers. A full system cleaning in a San Antonio home typically runs $450 – $750. Two-story homes and long ranch-style builds with extended single-story runs cost more because there’s simply more duct length to work through.

Video Inspection
We use a push camera to document what’s actually in the ducts before we touch anything. In older San Antonio homes, especially pre-1950s bungalows inside Loop 410, we’re often looking at duct separation or unsealed seams as much as dust. The camera shows both, and the photos we hand you afterward are tied to what we found, not a generic “dirty duct” shot.

Trusted Brands We Service in San Antonio
We service and clean ductwork tied to all major HVAC brands found in San Antonio homes, including systems paired with Honeywell and Aprilaire filtration products. We also stock replacement filters and components for those setups, so when the cleaning reveals a clogged or degraded filter housing, we can usually fix it that same visit. If your Aprilaire media cabinet is packed with dust, the cleaning is only half the fix. We’ll show you the filter on camera and give you a price to replace it before we touch it.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Per-vent pricing that balloons into a surprise total. San Antonio ranch homes have long single-story runs with many registers. A contractor quoting $29 per vent can turn a reasonable job into a four-figure invoice once the count is done. We quote one flat price per system, agreed before work starts.
- A quick register vacuum with no negative pressure. This is the biggest shortcut in the trade. Without negative-pressure extraction, loosened debris resettles in the ducts within weeks. We run Nikro HEPA vacuums at the air handler to pull debris out as we agitate.
- Same-day promises that dissolve on arrival. Some outfits quote same-day service to close the sale, then arrive without the right Rotobrush or Nikro attachments for older San Antonio duct material. We schedule for the time the system actually needs, and our techs carry equipment for galvanized, flex, and board duct.
- Leaky runs in pre-1950s attics. Inside Loop 410, especially in neighborhoods like Monte Vista, Beacon Hill, and Alta Vista, original galvanized ductwork has often separated at the seams. The ducts look dirty on camera, but the real problem is leakage. We photograph the separation and seal visible gaps before closing up.

FAQs About Air Duct Cleaning in San Antonio
Every 3 to 5 years for most homes, and longer if you run a high-efficiency filter and change it regularly. Homes with pets, recent renovations, or occupants with severe allergies may need it every 2 to 3 years. If a camera inspection shows minimal soiling, we’ll tell you to wait and save the money. Call (737) 727-2314 for an honest read.
Because per-vent pricing creates an incentive to count registers, not do the work. A San Antonio ranch home with a long single-story run might have 14 or 16 registers. One flat price per system means the quote we hand you before starting is the exact number on the invoice. No counting games.
Photos of the trunk lines, branch runs, air handler, and blower motor before and after cleaning, tied to the specific duct system type in your home. In a 1920s bungalow in Monte Vista, that means photos of the original galvanized runs and any seam separations we found and sealed. You see what we saw, not a generic dirty-duct shot.
No, and that’s deliberate. A proper cleaning on a standard San Antonio home takes 3 to 5 hours with the right equipment. We schedule based on what the system actually needs, and our techs arrive with the correct Rotobrush and Nikro attachments for your duct material. We won’t promise speed and then show up short-handed.
Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units when debris control is critical. Honeywell and Aprilaire filtration products are in stock for replacements we find during the cleaning. The tools match the duct material, which matters in older San Antonio attics with original galvanized runs.
