Air Duct Cleaning in San Antonio - Flat Price Per System, No Per-Vent Upsells

Trusted Air Duct Cleaning for San Antonio Homeowners

Air duct cleaning in San Antonio typically costs between $300 and $700 for a whole-home system, and the honest truth is that our Texas heat makes this service more necessary here than almost anywhere else. Your HVAC system pushes cooled air through ductwork for months at a stretch, and every time it cycles, it pulls in whatever’s floating around: Hill Country dust, pet dander, construction debris from the constant growth along Loop 1604, and the fine grit that settles into every home in Bexar County. At Linden Air Duct San Antonio, we’ve been helping homeowners breathe cleaner air since 2004 as part of the Threshold Group family. Call Marcus Veale and our team at (430) 233-7681 for a free estimate, and you’ll get a written price before any work starts, not a surprise invoice at the end.

Air Duct Cleaning Services

Air Duct Cleaning Services from Linden Air Duct San Antonio cover the full pathway your air travels: supply ducts, return ducts, registers, and the main trunk lines. Most San Antonio homes need this every 3 to 5 years, sooner if you have pets that shed, recent remodeling dust, or family members with allergies. We use negative-pressure extraction, which means the system is sealed and the air is pulled out rather than blown around, so what we remove actually leaves your house. A whole-home air duct cleaning in San Antonio typically runs $300 to $700, with the written price confirmed before we touch a single vent.

Full-System Negative-Pressure Cleaning

We connect a high-powered vacuum to your ductwork and run our Rotobrush agitation tools through every line. This combination loosens caked-on dust, then removes it under negative pressure so nothing escapes into your living spaces. The process takes about 3 to 5 hours for most single-family homes in the San Antonio area.

Register and Grille Restoration

Every vent cover comes off, gets cleaned, and goes back on looking better than it did. Years of San Antonio dust and humidity can leave registers discolored and sticky. We’ll tell you upfront whether yours need a deep clean or are better off replaced.

If a technician ever gives you a “per vent” price, be careful. That’s the bait. We give one flat price per system before work begins. Read more about our home services or compare with our Air Duct Cleaning in San Antonio main page.

HVAC Duct Cleaning

HVAC Duct Cleaning targets the ductwork connected directly to your furnace and air handler, the part of your system that moves cooled or heated air through your home. In San Antonio, where air conditioners run hard from May through October, your HVAC ducts collect more than just dust; they collect the fine particulate that settles when air flow slows between cycles. Linden Air Duct San Antonio cleans the full HVAC duct network including the plenum, the trunk lines, and the branch runs to each room. HVAC duct cleaning here runs $300 to $700 for a whole system, with the price written down before we start.

Plenum and Coil Area Cleaning

The plenum is the box where your ducts meet the furnace, and it’s one of the most neglected spots in any San Antonio home. We clean the plenum, the blower compartment access area, and the evaporator coil housing so mold, dust, and debris don’t get pulled back into the air you breathe.

Branch Run and Room Duct Service

Each room in your home has dedicated duct runs, and they don’t all collect dust at the same rate. Rooms on the south side of your house or rooms with exterior walls in the Texas sun tend to collect more because the system works harder to cool them. We clean each run individually and check for leaks or disconnects as we go.

Vent Cleaning

Vent Cleaning focuses on the visible parts of your air system: the supply registers where air comes out and the return grilles where air goes back in. It’s the part of the job you see every day, and it’s also where San Antonio dust, pet hair, and cooking grease tend to collect most visibly. Linden Air Duct San Antonio includes vent cleaning as part of every whole-home air duct cleaning service, and we can also clean vents on their own if that’s all you need. Vent-only cleaning runs between $150 and $300 depending on how many vents you have and how much buildup has accumulated.

Supply Register Deep Cleaning

Every supply register comes off the wall or floor, gets washed, and is inspected for rust, damage, or poor airflow. In San Antonio’s humid summers, registers in bathrooms and kitchens can develop surface corrosion faster than in other rooms. We’ll tell you if any register needs replacing and what a replacement costs before we do anything.

Return Grille Filter and Cavity Service

Return grilles pull air back into your system, and whatever they pull in ends up in your ducts. We clean the return cavities, check the filter housing for gaps that let unfiltered air bypass the filter, and make sure your return grilles are sealed properly. If you have a filter grille, we’ll also check whether the filter is the right size and recommend an upgraded option if your current one is leaving gaps, using air-quality products from Honeywell and Aprilaire.

Ductwork Cleaning

Ductwork Cleaning is the broadest term for what we do, and it covers the entire network of metal or flexible ducts running through your walls, floors, and attic. This is the job that addresses the dust you can’t see, the buildup inside your ductwork that keeps circulating every time your air conditioner kicks on. In San Antonio, homes built before 1990 often have metal ductwork that’s been in place for decades, while newer construction tends to use flexible duct lines. We handle both. Ductwork cleaning for a typical San Antonio home costs between $300 and $700, with the written price set before we begin.

Metal and Flexible Duct Handling

Metal ducts need agitation to break loose years of caked-on dust, and flexible ducts need a gentler approach so they don’t tear. Our techs are trained to identify what’s in your walls and treat each material appropriately. We also check for disconnected or sagging flex duct, which is a common problem in San Antonio attics where summer heat degrades the plastic outer liner.

Whole-Home Airflow Verification

After cleaning, we walk the house with you and verify airflow at each register. Weak airflow in one room usually means a duct problem somewhere: a kink, a disconnect, or a blockage. We check every run so you don’t get half a job and a room that’s still hot in August.

Air Duct Inspection

Air Duct Inspection is a standalone service for homeowners who want to know exactly what’s inside their ductwork before committing to a cleaning. We use inspection cameras to look inside your ducts, and we show you the footage on the spot. In San Antonio, inspections are common after a rodent issue in the attic, after major remodeling work, or when a home changes hands and the new owner wants to know what they’re dealing with. We charge $75 to $150 for a thorough inspection, and if you choose to proceed with cleaning, we’ll apply that amount toward the job.

Post-Remodel and Move-In Checks

New construction and remodeling leave dust you don’t want your family breathing for the next five years. Drywall dust, sawdust, and debris from a remodel in Alamo Heights or Terrell Hills settles into ducts quickly. We’ll inspect the system, show you what we find, and clean it if needed.

Rodent and Pest Damage Assessment

San Antonio attics are attractive to rodents, and rodents are hard on ductwork. We look for signs of nesting, chewed flex duct, and debris that can affect your air quality. If we find damage, we’ll document it with photos and give you an honest assessment of what needs repair versus what needs cleaning.

Speaking of repairs, if your inspection reveals a problem, our Air Duct Repair service includes a written guarantee on every job, with a free second visit if the repair fails. And if your dryer vent needs attention too, we offer Dryer Vent Cleaning as a separate service.

Residential Air Duct Cleaning

Residential Air Duct Cleaning is our primary focus, and it’s what we’ve done for San Antonio homeowners since 2004. Most residential jobs in the San Antonio area take 3 to 5 hours and cost between $300 and $700 for a complete system. The size of your home, the number of vents, and the amount of buildup all factor into the written price we give you before any work begins. We clean single-family homes, townhomes, and condos throughout Bexar County.

Homes With Pets and Allergies

Pet dander, hair, and dust mites collect in ductwork and recirculate every time your system runs. Homes with dogs or cats in San Antonio often need cleaning every 2 to 3 years rather than the standard 3 to 5. If someone in your household has allergies or asthma, cleaner ducts can make a real difference in how your home feels.

Older Homes With Original Ductwork

San Antonio is full of beautiful older homes in neighborhoods like Monte Vista, Alta Vista, and Jefferson, and many still have original metal ductwork. These systems collect decades of dust and sometimes have leaks or gaps we find during cleaning. We handle older ductwork carefully and tell you what we find, not just what we cleaned.

Commercial Air Duct Cleaning

Commercial Air Duct Cleaning covers offices, retail spaces, restaurants, and small commercial buildings throughout the San Antonio area. Commercial systems run longer hours and move more air than residential ones, which means they collect more dust, more debris, and more of whatever your business produces. Pricing for commercial air duct cleaning in San Antonio depends on building size, duct layout, and access, but most small to mid-size commercial jobs run between $500 and $2,500, quoted in writing before work begins.

Office and Retail Space Systems

Offices with rooftop units and shared ductwork need regular attention, especially in San Antonio where the AC runs nearly year-round. We work around your business hours where possible, and we schedule commercial jobs with minimal disruption to your operations. Our techs arrive in clean, marked uniforms, background-checked and photo-badged under the Threshold Standard.

Restaurant and Kitchen Exhaust Systems

Restaurants have unique air system needs: grease-laden air from kitchen exhaust, high heat from cooking equipment, and health code considerations. We clean the HVAC ducts that serve dining and kitchen areas, not just the exhaust hood, so your whole building breathes better. We use professional-grade equipment from Rotobrush and Nikro on commercial jobs.

If you’re managing a property in Selma, Fair Oaks Ranch, or anywhere in the San Antonio metro, we can assess your buildings. See our Air Duct Cleaning in Selma page or our Air Duct Cleaning in Fair Oaks Ranch page for area-specific information.

Brands We Service

We work on every make of HVAC ductwork and air system, but we’ve built particular depth with certain equipment brands over the years. On the cleaning side, we run Rotobrush and Nikro machines, which are the trade-trusted names in negative-pressure extraction and agitation tools. These aren’t consumer-grade rentals; they’re professional systems designed to handle the heavy buildup we see in San Antonio homes.

On the air-quality side, we install and service products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. That includes media filters, electronic air cleaners, UV systems, and whole-home purifiers. Whether you have a Honeywell system, an Aprilaire filter cabinet, or any other make, we can help.

Signs You Need a Pro Right Now

• Dust returns within days of cleaning your house. If you dust on Sunday and by Wednesday every surface has a fine layer again, your ducts are likely the source. The dust isn’t settling from outside; it’s being blown out of your registers every time the system cycles.
• Your energy bills climbed without a change in usage. When ducts are clogged, your system works harder to push air through. That means longer run times and higher CPS Energy bills, even when you haven’t changed the thermostat.
• You see visible dust or debris at your registers. Look closely at the slats on your supply vents. If you see darkened edges, fuzzy buildup, or actual debris, that’s what’s inside your ducts, and it’s not going to fix itself.
• Someone in your home has unexplained allergy or respiratory symptoms. Indoor air can be more polluted than outdoor air, especially in San Antonio where homes are sealed tight against the heat. If symptoms improve when you leave the house and worsen when you return, your ducts are worth investigating.
• You’ve recently finished a remodel or bought a home that sat vacant. Construction dust settles in ductwork and keeps circulating for months afterward. And vacant homes don’t move air, so everything that drifted in just sits there waiting for the system to kick on again.
