Fast, Reliable Air Duct Cleaning Across Alamo Heights
Air duct cleaning in Alamo Heights typically runs $350-$850 for a full residential system, with most jobs completed in a single visit and camera-verified before we leave. We’re usually on-site within 24 hours of your call, and our trucks carry the equipment to handle Alamo Heights’s distinctive mid-century retrofit ductwork without a return trip.
We’ve been working the 78209 zip code long enough to know what we’re walking into: homes built in the 1940s through 1960s that were never designed for central air, with ductwork threaded through wall cavities and baking attics decades after the fact. That matters. A technician who treats your Alamo Heights Tudor like a 2015 suburban build will miss the real problems - the leaky joints, the long attic runs, the pollen strata packed into original galvanized trunks. Our Air Duct Cleaning team knows the difference. Call (866) 347-2063 for a free estimate, or keep reading to understand what your house is actually dealing with.

Our Air Duct Cleaning Services in Alamo Heights
Full System Cleaning
This is what most Alamo Heights homes actually need. A full system cleaning addresses every component - supply trunks, return trunks, branch lines, and register boots - not just the parts you can see from the hallway. In Alamo Heights’s retrofitted systems, debris collects in the long attic runs and hidden junctions that discount cleaners never reach. We use Rotobrush mechanical agitation paired with HEPA-filtered Nikro vacuum collection to dislodge and remove buildup without damaging original metalwork or degraded flex-duct liner. Every full system clean includes video inspection so you see what came out and what the ducts look like now.
Video Inspection
We camera-inspect every Alamo Heights job before touching a tool. In mid-century homes with mixed metal and flex systems, a video walk reveals disconnects at joints, liner delamination, and pollen strata that a surface glance misses. The camera doesn’t lie - and it gives us both a baseline and a record. After cleaning, we run the camera again. You’ll see the difference, and you’ll know the job was done right.
Supply Duct Cleaning
Supply ducts in Alamo Heights homes face a specific burden: negative pressure from the blower pulls unconditioned attic air through every leaky joint, and that attic air carries Hill Country pollen, dust, and 150°F summer heat. The supply stream ends up loaded with what the attic contains. We seal accessible leaks during cleaning where possible, and we always verify that supply trunks are actually delivering clean air - not recirculating attic contamination.
Residential Duct Cleaning
Our residential work in Alamo Heights focuses on the realities of owner-occupied, long-held homes. You’ve lived there twenty years, or your parents did. The ductwork predates your ownership and has cycled through multiple HVAC upgrades. We account for orphaned branches, mixed materials, and aging insulation. No scare tactics, no upsell to replacement unless the system is genuinely beyond service. Just honest assessment and work you can verify.
Commercial Duct Cleaning
Alamo Heights’s commercial spaces - medical offices along Broadway, retail near the Alamo Quarry Market, professional buildings - require scheduled maintenance that doesn’t disrupt operations. We work evenings and weekends, provide documentation for facility managers, and maintain the same camera-verified standard as our residential jobs.
Return Duct Cleaning
Return ducts are the intake side, and in Alamo Heights’s older homes they’re often the most compromised. Retrofit return chases were frequently improvised from wall cavities with minimal sealing, pulling air from unintended spaces. We clean and inspect return pathways for proper isolation, because a return duct drawing from a hot attic or wall void undermines everything the supply side delivers.

Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Tan cedar-pollen strata in original galvanized ducts. Homeowners often mistake visible register dust for the real problem. The deeper threat is layered Ashe juniper pollen packed inside 1950s-60s metal trunks, re-releasing into your living space every heating and cooling cycle. Only full-system mechanical agitation with video verification removes it.
- Flex-duct liner degradation from extreme attic heat. San Antonio attic temperatures exceed 150°F regularly, and retrofit flex runs in Alamo Heights’s unconditioned attics suffer thermal cycling that delaminates the liner. We inspect for this damage during cleaning and flag it before fiberglass particles enter your airstream.
- Orphaned duct branches from decades of HVAC upgrades. Multiple equipment replacements have left many Alamo Heights homes with disconnected or capped branches that trap stagnant debris. Our camera inspection locates these dead legs so they’re addressed, not ignored.
- Superficial cleaning by discount operators. A brush on a shop vac run to the register boot doesn’t touch the long attic branches where Alamo Heights’s real buildup lives. We clean the full reachable system, verified by camera, because partial work is wasted money.
Pricing for Air Duct Cleaning in Alamo Heights, TX
Most full residential duct cleaning jobs in Alamo Heights fall between $350 and $850, depending on system size, accessibility, and condition. A typical 1,800-square-foot ranch with retrofitted attic ductwork runs toward the middle of that range. Larger homes with multiple zones, or properties requiring extensive access panel installation, may reach $1,100-$1,400. Video inspection is included; duct sealing or minor repairs are quoted separately before any additional work.
What moves the number: the mix of metal and flex duct (metal takes longer to clean properly), the number of registers and returns, whether we need to create access points in finished spaces, and the degree of buildup - heavy cedar-pollen strata require more agitation cycles than routine dust accumulation. We disclose the full price before starting. The quote you get on the phone matches the invoice. No bait coupons, no surprises at the door.
Current standing offers: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-up, and a permanent 5% senior and veteran discount. Call (866) 347-2063 for your exact quote - estimates are free.

FAQs - Air Duct Cleaning in Alamo Heights
The tan residue is Ashe juniper (mountain cedar) pollen that has infiltrated your duct system through leaky joints and accumulated in layers over decades - standard filters won’t stop what’s already inside the ductwork, and leaky retrofitted systems pull in new pollen continuously. On a Tudor revival off Jackson Keller Road, our crew cracked open a 1950s galvanized return trunk and found half an inch of tan, fibrous cedar-pollen strata - multiple distinct seasonal layers - because the home’s leaky joints were pulling unconditioned attic air (and Hill Country pollen) directly into the supply stream. We used Rotobrush agitation and a HEPA-filtered Nikro vacuum to remove 40+ years of pollen buildup without disturbing the original metal ductwork. Call (866) 347-2063 for a free estimate - we’ll camera-inspect your system and show you what’s actually in there.
Yes, both materials can be cleaned in place with the right equipment and technique, which is exactly what we do in Alamo Heights homes every week. Metal ductwork withstands mechanical agitation well; flex duct requires controlled brush speed and vacuum pressure to avoid damaging the liner, especially when heat degradation has already begun. Our video inspection first identifies which sections are metal, which are flex, and which are compromised. We adjust our approach accordingly and verify results camera-in-hand. Call (866) 347-2063 to schedule - estimates are free.
Duct cleaning removes the accumulated pollen reservoirs that recirculate with every blower cycle, so yes - it reduces the indoor load your family breathes, though it doesn’t eliminate outdoor exposure. The critical factor in Alamo Heights is that leaky retrofitted systems re-contaminate quickly if joints aren’t sealed; we inspect and address accessible leaks during cleaning to slow re-infiltration. For households with severe cedar allergies, we also evaluate whether the duct system’s negative-pressure draw is pulling directly from attic or wall voids. Call (866) 347-2063 and we’ll assess your specific setup.
It is safe when done with professional HEPA-contained equipment that captures fibers at the source rather than redistributing them, which is why we use Nikro HEPA-filtered vacuums on every Alamo Heights job. However, degraded flex-duct liner or disintegrating asbestos-containing duct wrap (present in some 1960s installations) requires special handling. We camera-inspect first to identify the material type and condition. If we encounter hazardous materials, we stop, inform you, and recommend the proper remediation path. No surprises, no shortcuts. Call (866) 347-2063 to schedule an inspection.
Every 3 to 5 years for typical households, and every 2 to 3 years for homes with allergy-sensitive residents, pets, or visible reaccumulation of the tan pollen residue. Alamo Heights’s specific conditions - the intense cedar-pollen season, extreme attic heat accelerating material degradation, and the inherent leakiness of retrofitted systems - mean these homes accumulate debris faster than newer construction with purpose-built ductwork. We recommend a video inspection at the 3-year mark to assess actual condition rather than guessing. Call (866) 347-2063 to book - estimates are free, and we’ll show you what your ducts look like inside.
