Air Duct Cleaning Company in San Antonio, TX
Air duct cleaning in San Antonio usually runs $300 – $550 for a typical single-system home, and the reason has everything to do with what’s blowing through our air. Cedar pollen from the Hill Country, fine white caliche dust from construction, and the occasional gritty layer left by Saharan dust events all settle in ductwork faster here than in most Texas cities. Add in an AC that runs nearly year-round, and you’ve got a system that re-circulates the same allergens through every room. We’re Cardinal Air Duct San Antonio, part of the Relay Home Co. family, and every job starts with a written price before a single vent is touched. Call (254) 347-3897 for a free estimate.
Why San Antonio Homes Are Different
San Antonio’s housing stock spans several very different eras, and each one presents its own ductwork challenges. Inside Loop 410, you’ll find pier-and-beam bungalows in neighborhoods like Jefferson and Beacon Hill where techs regularly encounter ducts collapsed under floors, chewed by rats and squirrels, and coated in a fine white caliche dust that re-circulates every time the AC kicks on. Outside the loop, the 1970s – 1990s suburban tract homes that make up much of the city’s housing stock often still have original flex duct, which sags over time and collects debris in the low points.
The far west and north sides tell a different story. New builds there are tighter, which is good for efficiency, but many left the factory with poorly sealed duct connections that pull attic air and insulation particles into the system. And the climate ties it all together: hot, humid summers with mild winters mean your AC runs almost constantly from March through October, pulling Hill Country cedar and oak pollen through return registers and into the ducts. Cedar fever season alone pushes many homeowners to schedule their first cleaning by late winter.
Styles & brands we work with
Our Main San Antonio Services
Most San Antonio homeowners call us for one of two reasons: they’ve never had their ducts cleaned and the allergy season finally pushed them over the edge, or they just bought a home and don’t know what’s living in the ductwork. All three of our core services are covered by the 365-Day Done Right Promise: if it’s not right within a full year, we return and make it right at no charge.
Dryer Vent Cleaning in San Antonio
Dryer vents in San Antonio clog with a mix of lint and the same fine dust that gets into everything else here. In older pier-and-beam homes, vents often run under the floor with sharp bends that trap lint quickly. Our team uses a rotary brush system to break the buildup free, then negative-pressure extraction to pull it out rather than pushing it into the wall cavity. You’ll get before-and-after photos of your vent, a written price before we start, and a vent that actually exhausts properly again. Learn more about Dryer Vent Cleaning in San Antonio.
Air Duct Cleaning in San Antonio
Full air duct cleaning in San Antonio is the service most homeowners book when allergies spike or after a remodel sends drywall dust through every register. We connect a Nikro HEPA vacuum to the plenum to create negative pressure, meaning loosened debris goes straight into the vacuum, not back into your living room. Then rotating brushes from Rotobrush work the inside of each duct run. For homes inside Loop 410 with older flex duct, we inspect every run first because sagging or cracked sections are common and need repair before cleaning makes sense. See the full breakdown on our Air Duct Cleaning in San Antonio page.
HVAC Cleaning in San Antonio
HVAC cleaning in San Antonio goes beyond the duct runs and addresses what’s happening at the unit itself: evaporator coils caked with dust, a blower wheel that’s lost most of its airflow, and a drain pan that’s been growing things in the humidity. Our technicians open the air handler, clean the coils and blower assembly, and sanitize the drain line so condensation flows properly. Given how much the AC runs in San Antonio, a clean coil can noticeably improve airflow and cooling performance. Full details are on our HVAC Cleaning in San Antonio page.
