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.

AfterAir Duct Cleaning in San Antonio, TX
Dryer vent cleaning in San Antonio has to contend with something most cities never see: caliche dust. The fine calcium-carbonate powder that drifts off construction sites along Loop 1604 and US 281 settles into dryer vents alongside the usual lint, and because lint is slightly sticky from fabric softener residue, the two bond into a paste that hardens as it bakes in attic heat. That means a vent that would take 20 minutes to clean in a milder climate can take twice as long here. We serve every San Antonio neighborhood with written pricing before any work starts, and every job ends with a documented photo record of the inside of the vent. Call (806) 606-6902 for an exact price before a single panel comes off.
Why San Antonio Homes Are Different
San Antonio’s ongoing cedar fever season loads ductwork with one of the densest allergen payloads of any U.S. city. From December through February, Ashe juniper pollen is so heavy the air visibly hazes yellow, and homeowners seal windows and run HVAC systems continuously for weeks. Because the AC season runs roughly 9 to 10 months a year, that cedar pollen gets pulled into return plenums on top of whatever was already there. By late February and into March, the accumulation in San Antonio ducts is routinely worse than what we see in Houston or Dallas at the same time of year.
The housing stock compounds the problem. The massive suburban buildout along US 281 and Loop 1604 from the 1970s through the 2000s left San Antonio with enormous tracts of slab-on-grade, attic-ducted homes whose original flex ductwork is now 20 to 40 years old and baking at 150°F or more each summer. Closer to downtown, neighborhoods like Monte Vista, Mahncke Park, and the King William district often have improvised duct runs from original central-air conversions, with decades of undisturbed debris accumulation inside them.
Then there’s the caliche. San Antonio sits at the edge of the Edwards Plateau, and the relentless suburban construction spreading north and west along 1604 constantly disturbs that fine calcium-carbonate dust. It gets pulled directly into HVAC intakes of nearby occupied homes, where it compacts into a gritty layer at the bottom of return plenums and filter boxes. It’s a different kind of debris than the lighter organic dust typical in higher-humidity Texas cities.
Our Main San Antonio Services
Homeowners in San Antonio call us most often about two jobs: getting the accumulated cedar pollen, caliche dust, and construction debris out of their air ducts, and cleaning the HVAC components that move air through them. Each service has its own San Antonio page with detailed pricing and local conditions.
Air Duct Cleaning in San Antonio
Whole-system Air Duct Cleaning in San Antonio means running negative-pressure extraction through every duct run, from the return registers to the supply side, with a camera recorded before and after. San Antonio’s unique combination of cedar pollen, caliche dust, and a near year-round cooling season means the debris we remove is often a compacted layer that needs agitation to break loose before extraction. Homes along the 1604 corridor with 20 to 40 year old flex duct are the most likely to have substantial accumulations.
HVAC Cleaning in San Antonio
HVAC Cleaning in San Antonio covers the mechanical parts of the system: the blower motor and wheel, evaporator coil, drain pan, and the inside of the air handler. San Antonio’s extended cooling season keeps the evaporator coil wet for much of the year, which is why coil cleaning here is less about efficiency and more about preventing the biological growth that feeds on accumulated caliche dust and cedar pollen. A fouled coil in San Antonio doesn’t just reduce airflow, it becomes a breeding surface.

BeforeAfterDryer Vent Cleaning in San Antonio
Dryer vent cleaning in San Antonio is the service we recommend homeowners schedule every 18 to 24 months, purely because of what the local climate and long vent runs do to lint accumulation. Many homes out in the 1604 corridor and beyond have laundry rooms on interior walls, which means the dryer vent has to travel 15 to 30 feet through a hot attic before it reaches the exterior wall, and every extra foot of run is another surface for lint to catch on. When that lint picks up caliche dust from the attic air, it becomes denser and slower to blow out, which is why San Antonio dryer vents clog faster and more completely than the national average. We document every cleaning with before-and-after photos from inside the vent, so you can see the difference between a genuinely clear run and a shop-vac on a stick. For more detail on our approach, see our Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Clothes are taking more than one full cycle to dry, or the exterior vent hood’s flap isn’t opening when the dryer runs.
What it costs in San Antonio
A stand-alone dryer vent inspection in San Antonio typically costs between $89 and $129, and includes a camera run the full length of the vent.
How we do it
We run a camera from the dryer connection through every foot of the vent run, then show you the recording and explain what we’re seeing at each elbow and transition.
Lint Removal
Signs you need it
You see visible lint at the exterior vent hood, or the dryer shuts down mid-cycle on its own and feels hot to the touch after a load.
What it costs in San Antonio
Full lint removal in San Antonio runs $130 to $260, depending on vent length, number of elbows, and whether the run goes through the attic or is a direct rear wall exit.
How we do it
We run a HEPA-filtered negative-air machine at the exterior vent while sending an air-driven brush through the full length of the run, then photograph the inside at the end to show the result.
Bird Guard Installation
Signs you need it
You hear scratching or chirping near the vent, or you’ve found nest material poking out of the exterior hood.
What it costs in San Antonio
A bird guard installation in San Antonio typically costs $85 to $155, depending on whether the vent is at roofline height or reachable from the ground.
How we do it
We remove any existing nest material, clean the vent run, and install a stainless guard over the exterior termination with a clamp that won’t work loose in San Antonio wind.
What Dryer Vent Cleaning Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Dryer vent inspection | $89 - $129 |
| Full lint removal and vent cleaning | $130 - $260 |
| Bird guard installation | $85 - $155 |
How often does a dryer vent really need cleaning in San Antonio?
Every 18 to 24 months for most San Antonio homes, and closer to annually if your vent runs 15 feet or more through an attic. Long attic runs collect lint faster because the heat increases static cling. Call us for an inspection price, and we’ll give you a written recommendation based on actual camera footage, not a generic schedule.
Is a clogged dryer vent actually dangerous?
Yes. Lint is combustible, and a restricted vent forces the dryer to run hotter, which is the exact condition that leads to dryer fires. It also burns through heating elements faster. A cleaned vent means lower dryer repair costs and a safer laundry room.
Duct Repair & Sealing in San Antonio
Duct repair and sealing in San Antonio means finding and closing the leaks that pull 150°F attic air into your supply runs in summer, and sealing the joints that let paid-for cooled air escape into the attic before it ever reaches a register. Homes built along US 281 and Loop 1604 from the 1970s through the 2000s are the most frequent candidates, because flex duct that has spent 20 to 40 years in San Antonio attic heat loses its outer jacket, sags between supports, and eventually tears at the connection collars. A 20% duct leak in San Antonio isn’t unusual, it’s what we expect to find in pre-2000 construction. The repair itself is detailed step by step on our Duct Repair & Sealing page.
Duct Sealing
Signs you need it
Rooms stay warm even with the AC running, utility bills stay high through the shoulder months, or you see a dust film on surfaces in rooms even with a clean filter.
What it costs in San Antonio
Whole-system duct sealing in San Antonio runs $800 to $1,800, depending on the number of accessible runs and whether we seal from the attic side or need to cut access panels.
How we do it
We locate every leak with a combination of thermal scanning and pressure testing, then seal each joint with mastic sealant or foil tape, depending on the joint type and duct material.
Flex Duct Repair
Signs you need it
You can feel cool air leaking in your attic, or the insulation jacket on visible duct runs appears torn, sagging, or flattened between supports.
What it costs in San Antonio
Flex duct section replacement in San Antonio typically costs $450 to $950 per full run from plenum to register, including new supports and sealing at both connections.
How we do it
We remove the failed section, install new flex duct cut to exact length, support it every 4 feet with saddles rather than strap hangers, and seal both ends before testing airflow.
What Duct Repair & Sealing Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Whole-system duct sealing | $800 - $1,800 |
| Flex duct section replacement (per run) | $450 - $950 |
| Duct leak diagnostic and pressure test | $150 - $250 |
Can duct sealing actually lower my cooling bill in San Antonio?
Yes. If your ducts are pulling attic air into the supply side, your AC is cooling 150°F air, which means it runs longer to hit the setpoint. Sealed ducts mean the system cools only the air it intended to cool. Our pressure tests show the leak percentage before and after, so you can see the difference in writing.
How do I know my ducts are leaking and not something else?
The telltale sign is rooms that stay warm with the AC running, combined with a clean filter and a running system. If conditioned air isn’t reaching a register, it’s escaping somewhere between the plenum and the room. A pressure test confirms it in minutes.
Air Quality & Sanitizing in San Antonio
Air quality and sanitizing in San Antonio is the service that addresses what cedar fever season and continuous AC operation leave behind in your ductwork. After months of running the system with sealed windows, all that Ashe juniper pollen, caliche dust, and summer condensation gets pulled into the return side, and left undisturbed, it feeds the kind of biological growth that gives a house that musty “AC smell” the first time the system kicks on in fall. We treat the plenums, the coil, and the first few feet of supply runs with an EPA-registered antimicrobial, then photograph every treated surface before closing the system back up. The full protocol is outlined on our Air Quality & Sanitizing page.
Odor Removal
Signs you need it
You notice a stale or musty smell when the AC first starts, and the smell fades as the system runs, which indicates odor trapped in the coil and drain pan rather than the ducts themselves.
What it costs in San Antonio
Whole-system odor removal in San Antonio runs $300 to $500, including treatment of the plenums, coil, and accessible supply runs.
How we do it
We clean the coil and drain pan, then fog the plenums and first truss of supply runs with an odor-neutralizing agent that absorbs the volatile compounds rather than masking them with fragrance.
Mold Treatment
Signs you need it
Visible growth appears on the inside of the supply register or on the coil face, or the AC smells earthy and stale every time it cycles on.
What it costs in San Antonio
Mold treatment in San Antonio typically costs $400 to $800, depending on the extent of the growth and whether the coil must be pulled for direct treatment.
How we do it
We clean the affected surfaces to remove the food source, apply an EPA-registered antimicrobial, then photograph every treated surface and document the chemical, batch number, and application time in your job record.
What Air Quality & Sanitizing Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Whole-system odor removal | $300 - $500 |
| Mold treatment (per system) | $400 - $800 |
| UV light installation | $600 - $1,200 |
Will sanitizing my ducts actually help with allergies during cedar fever season?
Sanitizing removes the accumulated biological material that can amplify allergy symptoms, but it won’t stop new pollen from entering your home. The best result is a system that’s been cleaned, sealed, and sanitized, with a fresh high-MERV filter installed at the return. We can quote that as a single written price before we start.
How do I know the sanitizing was actually done and not just sprayed at the register?
Every job includes a documented photo record of the inside of the plenums and the coil before and after treatment. If we couldn’t photograph it, it wasn’t done. That record is yours to keep as part of the standard job file.

FAQs About Air Duct Cleaning in San Antonio
Most San Antonio appointments are scheduled within 2 to 4 business days, and our office can confirm a date at the time you call. We coordinate all scheduling from our San Antonio office, and the crew arrives as a team of two with all equipment on the truck.
For most San Antonio single-family homes, no. Duct cleaning, vent cleaning, and repairs are interior mechanical work, and most HOAs only review exterior modifications like exterior vent hood changes. If in doubt, we can place the exterior hood exactly where the existing one sits to avoid any review trigger.
Late February through March is when San Antonio ducts carry the heaviest allergen load, because sealed windows and continuous AC operation have been pulling cedar pollen into the returns all winter. Cleaning at the tail end of cedar season removes the bulk of it before the spring cycle starts. Get a written price first, and see the before-and-after photos to verify the work was done.
Call (806) 606-6902 for a written price on any of these services in San Antonio. Every job starts with a written quote, every run is photographed before and after, and the 365-Day Done Right Promise means the work is accountable long after the truck leaves.
