Floresville’s duct systems get worked hard. Summers above 95°F mean your AC runs nearly year-round, and the clay-heavy Blackland Prairie soil under many of these homes doesn’t sit still. That combination creates problems we see on this page’s streets every single week, and we’ll explain exactly what we find and what it costs to put right.

Air Duct Cleaning done right means more than running a brush through a return. It means understanding why the ducts failed in the first place. In Floresville, that reason is almost always the ground under the house.

We work throughout Floresville every week. Dispatch and scheduling are coordinated from the brand’s San Antonio office, but the crews serving Floresville know the streets, the housing stock, and the soil. You don’t have to explain what a pier-and-beam crawlspace is. You don’t have to argue about whether that musty smell is real. We already know.

Every Floresville job runs on the same standard: a live trackable arrival window, before-and-after photos of your own ducts, and a written price handed to you before a single vent is touched. That’s The Relay Standard, and it applies to every booking without exception. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it’s the longest-standing satisfaction window we know of in the trade.

Omar Haddad leads the Cardinal Air Duct San Antonio team, and he holds every technician to the same rule: when you arrive at a Floresville home, you know the tech’s name before they knock, they’re background-checked, they’re in uniform, and they carry Rotobrush brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. No truck-mounted shop-vac shortcuts. No vague estimates. No phone tag. A live person answers when you call, 24/7.

Air Duct Inspection in Floresville

Air Duct Inspection in Floresville uncovers what’s actually happening inside your duct runs before any cleaning starts, and it’s the single most important step for older homes in this city. Cameras map every bend, joint, and register boot. The inspection shows disconnections, crushed sections, water damage, and debris that a visual check from the vent opening misses. For a Floresville home, it costs $150 to $350 depending on system size and access, and it’s credited toward the full cleaning if you book within 30 days.

Given how many pier-and-beam homes we inspect in Floresville, we rarely go into a clean cold.

What We Check in Pier-and-Beam Crawlspaces

Clay soil movement loosens duct joints here. The shrink-swell cycle, wet season, then drought, then wet again, shifts piers by fractions of an inch. Over years, that’s enough to separate a return duct at the register boot. We check every boot, every joint, and the flex duct in flooded crawlspaces for moisture retention. Water that sits in flex duct insulation grows mold, and a basic cleaning without addressing the water source means the smell returns in weeks.

What a Camera Inspection Tells You

A camera view shows dust coating, moisture staining, and joint separation that a visual check from the register can’t reach. In mid-century Floresville homes, the return runs often run under the house where humidity is high. The camera confirms whether the return is pulling conditioned air from the crawlspace instead of from inside the home. This isn’t information for its own sake. It’s the difference between paying for a clean that lasts and paying for one that doesn’t.

Residential Air Duct Cleaning in Floresville

Residential Air Duct Cleaning in Floresville is the job we do most often, and it runs $350 to $750 for a typical single-system home under 2,500 square feet. The work includes source removal of dust and debris from both supply and return ducts, sanitizing where needed, and sealing accessible joints with mastic. For older two-story homes or homes with complex duct layouts, expect $650 to $1,100. The crew arrives with Rotobrush rotary brush equipment and Nikro HEPA-filtered negative-pressure extraction, which means the loosened debris goes straight into the vacuum, not back into your living room.

Floresville’s housing stock spans original 19th-century wood-frame homes near the courthouse square, mid-century ranch-style houses with pier-and-beam foundations, and newer 2000s to 2020s developments on concrete slabs. Each type has different failure modes. The older homes often have narrow, combined supply and return runs that standard brush agitation tools can’t fully reach. The ranch homes have flex duct in humid crawlspaces. The newer slab homes often run ducts through attics that bake in the South Texas sun, degrading the flexible connectors at the plenum within a decade.

Sealing Work Often Follows the Clean

In a mid-century ranch off Pecan Street, our tech found a return duct separated at the register boot under a pier-and-beam crawlspace, pulling damp, moldy air into the system. After camera inspection mapped the gaps, we ran negative-pressure source removal with HEPA filtration on all supply and return ducts, then sealed the joints with mastic. Airflow came back to spec and the musty smell was gone within a day. That sealing work runs an additional $150 to $400 depending on how many joints need attention, and it’s the real fix for most older Floresville homes. Cleaning without it just means you’ll be calling someone else to clean again next year.

Slab Homes on the Newer Side of Floresville

If you’re in a 2000s or 2010s development off Highway 181, your ducts are likely in the attic. That means heat degradation. Duct tape dries out. Flexible connectors at the plenum crack. Cleaning here requires working in tight attic spaces, and our techs bring Abatement Technologies containment units to protect the living space during the job. The cleaning process for a slab home runs $400 to $800, and we always recommend an inspection first so you can see exactly what condition the attic runs are in.

Trusted Brands We Service in Floresville

We service and clean systems from every major manufacturer you’re likely to have in a Floresville home, and we stock common replacement parts for Honeywell, Aprilaire, and Guardsman filtration products locally. If your system needs new media filters, we carry them on the truck. If the duct work needs parts after a camera inspection shows separation or crush points, we can usually handle the repair the same visit. That means fewer trips back, faster resolution, and a written guarantee on every repair with a free second visit if it fails. The equipment we use on every Floresville job includes Rotobrush rotary brush systems, Nikro HEPA-rated vacuums, and Abatement Technologies containment units. This is professional-grade equipment, not a truck-mounted shop-vac shortcut.

Common Air Duct Cleaning Problems We See in Floresville Homes

• Clay soil movement loosens duct joints on pier-and-beam homes. When the Blackland Prairie soil expands and contracts, piers shift enough to separate duct runs at the boots. Cleaning without resealing those joints means the system re-fouls within months, because the return keeps pulling crawlspace air.
• Original 19th-century wood-frame homes have narrow combined supply and return runs. The ducts in these older homes were built for a different era, often with tight turns and restricted diameters that standard brush agitation tools can’t fully reach. Debris stays behind, and airflow stays poor.
• Flex ducts in flooded crawlspaces hold moisture and grow mold. After a heavy rain season, crawlspaces in Floresville can flood. Flex duct insulation soaks it up. A basic cleaning that doesn’t address the water source leads to rapid mold regrowth and a musty smell that comes back fast.
• Newer slab homes bake their attic ducts in South Texas heat. Attic temperatures in a Floresville summer can hit 140°F. That degrades mastic, cracks tape, and makes flexible connectors brittle. Dust gets sucked in through the cracks, and the system loses efficiency every season it runs.
