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.

We know Alamo Heights. Not just the streets, but the houses themselves – the 1940s ranches off Alamo Heights Boulevard, the bungalows tucked under mature live oaks near Cambridge Oval, the mid-century builds along Broadway. Most of these homes have original ductwork that predates modern filtration standards. Our crews work these attics and crawl spaces every week, and we understand what decades of pollen, caliche dust, and piecemeal renovation leave behind. This isn’t a generic cleaning job. It’s a local one.
If you’re in the 78209 ZIP code or anywhere in Alamo Heights, we can schedule a visit and give you a firm written price before we touch a single register.
Why Linden Air Duct Cleaning Is Alamo Heights’s Preferred Air Duct Cleaning Company
Since 2004, Linden Air Duct Cleaning has operated under the Threshold Verified standard, and that matters here more than in most places. Alamo Heights homeowners tend to be protective of their houses – these are older homes, many with original details worth preserving, and the people who live here want to know exactly who is coming through the door. That’s why every technician we send is background-checked, identity-verified, and photo-badged. Before your appointment, you receive the tech’s name and photo. At the door, they show a photo ID badge. Every time. Marcus Veale, who leads our team, set that protocol and it has not changed.
Homeowners in Alamo Heights call us because the work holds up. Our crews have cleaned systems in nearly every part of this city, from the shaded streets near the McNay Art Museum to the newer infill builds off Nacogdoches Road. Repeatedly, we find the same things: original galvanized sheet-metal trunks feeding into flex runs added during 1980s and 1990s remodels, return plenums caked with years of live-oak pollen, and disconnected runs hidden in finished walls. Knowing what to expect in these houses means we can give accurate pricing up front and do the job correctly the first day.
And when you call, a live person answers. No voicemail loops, no automated system. That’s true at 2 p.m. and at 2 a.m.
Vent Cleaning in Alamo Heights
Vent cleaning in Alamo Heights is different from vent cleaning in a newer San Antonio subdivision, because the vents here are often original to homes built between the 1920s and early 1960s. Those old stamped-steel registers and sidewall grilles collect a particular kind of debris: fine caliche dust mixed with live-oak pollen, compacted by decades of air pressure into a pale tan film that regular vacuuming never reaches. Our Air Duct Cleaning team removes the registers, cleans the boot and the first few feet of the run, and replaces everything carefully – especially in homes where the registers are original and the homeowner wants them preserved.
Homeowners in Alamo Heights typically need vent cleaning when they notice dust returning to surfaces within days of housekeeping, when allergies spike in March during live-oak season, or when one register simply isn’t pulling air the way it used to. For supply and return vent cleaning as part of a full system job, expect to pay $40 to $80 per vent path when bundled with whole-house cleaning. We give one flat price per system before work starts, so you’ll never get charged per-vent add-ons at the end of the day.
Supply Vent Restoration
Many Alamo Heights supply vents are painted over or sealed shut by previous owners. We free them without damaging the surrounding plaster or drywall, then clean the boot and the visible portion of the run.
Return Grille Deep Cleaning
Return grilles in Alamo Heights pull an enormous volume of air, which means they trap an enormous volume of everything the air carries. We remove and soak them, then clean the chase behind the grille before sealing the grille back into place.
Ductwork Cleaning in Alamo Heights
Ductwork cleaning in Alamo Heights means cleaning the entire system: supply trunks, return trunks, branch runs, boots, and the air handler. For $450 to $900 on a typical single-system home, we use negative-pressure extraction with HEPA filtration, agitation tools, and source removal to pull out what has accumulated over decades. In this city, that’s rarely just dust. It’s compacted live-oak pollen, caliche fines, pet hair, and often drywall dust from past remodels that contractors left inside the ducts. We also inspect for disconnected or crushed runs while the system is open.
This full-system approach matters in Alamo Heights specifically because so many homes have mixed-era ductwork. Original riveted sheet metal feeds into flex duct spliced in during a remodel, and if you only clean the visible flex runs, you leave the bulk of the contamination inside the metal trunks. We clean both. That’s the difference between a surface job and a real cleaning.
Original Sheet-Metal Trunk Cleaning
Original galvanized trunks in Alamo Heights homes hold up well, but they have seams and corners where decades of debris compacts into a hard crust. We use agitation tools designed for metal duct interiors, then extract under negative pressure so nothing escapes into your living space.
Mixed-Era System Inspection
When a home has original metal duct with flex spliced in, we camera-inspect the transition points before and after cleaning. Crushed or disconnected flex runs are common behind finished walls, and a cleaning that never finds them leaves the real problem unfixed.
Trusted Brands We Service in Alamo Heights
Our crews work with professional-grade equipment from Rotobrush and Nikro, and we service systems using air-quality products from Abatement Technologies, Guardsman, Honeywell, and Aprilaire. Since Alamo Heights homes frequently have original duct materials paired with modern components, we stock the connectors, mastic, and filter media needed to service these mixed systems without a second trip. If your system has a branded filtration component from any of these manufacturers, we’re familiar with it and can work around it during the cleaning. We don’t push replacement parts you don’t need. We clean what’s there and tell you honestly what condition it’s in.
Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Compacted caliche and pollen cake inside return plenums. The fine limestone dust common to this part of Bexar County mixes with humidity and live-oak pollen, forming a pale tan crust that a standard vacuum won’t lift. It requires agitation and negative-pressure extraction.
- Disconnected flex runs behind finished walls. Remodels in the 1980s and 1990s often extended ductwork without replacing the original trunk system. Those splices fail over time, and a disconnected run means conditioned air blows into a wall cavity instead of a room.
- Crushed sheet-metal sections in low attic cavities. Older Alamo Heights homes have tight attics where original metal duct runs pass through narrow clearances. Storage, cable work, or simple age can crush a section, restricting airflow to entire rooms.
- Surface-only cleanings that miss the original trunks. We regularly meet homeowners who paid for a cleaning elsewhere and later learned the crew only cleaned visible flex runs. The original riveted sheet-metal trunks, where most of the debris sits, were never touched.
Pricing for Air Duct Cleaning in Alamo Heights, TX
A typical whole-home air duct cleaning in Alamo Heights runs $450 to $900 for a single HVAC system. Smaller homes with one system and accessible ductwork fall toward the lower end. Larger homes, or systems with multiple returns, crawl-space access issues, or heavily compacted debris, land at the higher end. Video inspection runs $125 to $200 as a standalone service, and supply or return duct cleaning as a focused job starts around $250. We put the full price in writing before any work begins, and that number does not change unless you approve a change in writing first. Call (980) 447-2498 for a free estimate.

FAQs About Air Duct Cleaning in Alamo Heights
Every three to five years is the right interval for most Alamo Heights homes. If you have mature live oaks dropping heavy pollen onto your roof and into your return air every March and April, and you’re sensitive to mountain cedar from December through February, cleaning every three years keeps indoor particulate levels down. Homes with pets, recent remodels, or smokers in the house may need it more often. Call (980) 447-2498 and we’ll tell you honestly whether your system needs cleaning now or can wait.
That cake is compacted caliche dust mixed with live-oak pollen and ambient humidity. Caliche is the fine limestone particulate common across Bexar County, and in Alamo Heights it gets pulled into return plenums, where it binds with organic pollen and hardens over time. It won’t vacuum out with a standard shop vac. It requires agitation and negative-pressure extraction, and our crews deal with it regularly in this part of town.
Yes. Every full-system cleaning includes a camera inspection of accessible duct runs before and after the cleaning. In Alamo Heights homes with mixed-era ductwork, disconnected flex runs and crushed sheet-metal sections are common, and finding them is often what actually solves uneven airflow and musty odors. If we find a problem, we show you the footage and give you a written price to fix it.
Yes. Original galvanized sheet-metal ducts in Alamo Heights homes are durable, and we use agitation tools rated for metal interiors, not high-pressure air alone. The key is negative pressure with HEPA filtration so nothing gets blown into the house. Our crews have cleaned hundreds of these original systems without damage, and every repair we perform carries a written guarantee with a free second visit if the repair fails.
Caliche dust is finer and more adhesive than typical household dust, which means it compacts into harder deposits inside ducts. It binds with pollen and humidity, forming a crust that standard brush-and-vacuum methods can’t fully remove. Our process uses agitation, source removal, and HEPA-filtered negative pressure to lift and capture it. That’s why Alamo Heights systems often need the full method, not a quick surface clean.
