Our Air Duct Cleaning Services in Alamo Heights
Residential Duct Cleaning
Most Alamo Heights homes were built before modern sealed-duct standards existed. Original sheet-metal trunks from the 1940s and 1950s often have flex-duct additions from 1980s or 1990s HVAC upgrades, creating ledges where debris accumulates permanently. Our residential service addresses the full pathway — supply and return — using Rotobrush agitation to dislodge material that vacuum-only methods leave behind. Typical Alamo Heights residential jobs run $280–$450 depending on system size and accessibility.
Commercial Duct Cleaning
Alamo Heights’s commercial corridor along Broadway and Nacogdoches includes medical offices, retail spaces, and professional buildings in converted historic structures. These present unique challenges: mixed duct materials, restricted access hours, and occupancy-sensitive scheduling. We use Nikro portable systems when truck-mounted equipment isn’t practical, and we coordinate around your business hours. Commercial duct cleaning in Alamo Heights typically starts at $400 for smaller suites and scales based on square footage and system complexity.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces — and in Alamo Heights, they often push cedar pollen and caliche dust right along with it. Many local homes have supply registers that were relocated from floor to ceiling positions during mid-century renovations, leaving capped stubs that act as permanent dust traps. Our supply duct service includes video inspection to locate these problem sections before cleaning begins. Supply-only cleaning in Alamo Heights runs $180–$320.
Return Duct Cleaning
Return ducts draw air back to your HVAC system, making them the primary collection point for household particulate. In Alamo Heights’s larger homes — many exceed 3,000 square feet — return pathways are often undersized for modern HVAC loads, creating turbulence that deposits debris at joints and transitions. We inspect return plenums and trunk lines for accumulation patterns specific to high-ceiling, high-square-footage homes. Return duct cleaning in Alamo Heights typically costs $160–$280.
Video Inspection
Before we clean any Alamo Heights system, we run a video inspection. This isn’t optional — it’s how we find the dead-leg sections, capped stubs, and flex-duct separations that are routine in this ZIP code. Our camera system identifies problems that a standard visual check misses, and we share the footage with you. Video inspection as a standalone service runs $120–$180; it’s included at no charge when bundled with full system cleaning.
Full System Cleaning
Full system cleaning covers supply ducts, return ducts, trunk lines, plenums, and registers — the complete air pathway. For Alamo Heights homes with original or partially upgraded ductwork, this is usually the right choice. We combine Rotobrush agitation with HEPA-filtered negative air pressure from Abatement Technologies equipment, then finish with access panel sealing to prevent humid attic air from re-entering. Full system cleaning in Alamo Heights ranges from $380–$550 for typical single-family homes.

Trusted Brands We Service in Alamo Heights
We don’t use generic equipment. Our Rotobrush and Nikro cleaning systems are the same tools specified for commercial and industrial duct maintenance. For air quality enhancement, we work with Aprilaire media filters and Abatement Technologies HEPA filtration when customers want to upgrade beyond standard cleaning. We stock common replacement components for Alamo Heights’s most prevalent HVAC brands, so if our inspection reveals a disconnected flex duct or failed seal, we can often address it during the same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Dead-leg duct sections from retrofitted systems. Many Alamo Heights homes had floor or sidewall registers converted to overhead supply between the 1960s and 1990s. The original stubs were capped but rarely removed, creating permanent dust traps that standard cleaning misses without video inspection and targeted agitation.
- Caliche dust and cedar pollen bonded to sheet-metal ledges. The alkaline soil of the Hill Country produces fine caliche particulate; combined with Ashe juniper pollen from December through February, this material crusts on original sheet-metal trunk interiors. Vacuum-only cleaning won’t dislodge it — agitation with a Rotobrush system will.
- Humidity-driven mold in flex-duct additions. Gulf moisture reaches Alamo Heights consistently, and attic humidity peaks during our long cooling season. Flex-duct additions from decades-old HVAC upgrades often lack proper vapor sealing, allowing mold establishment that recirculates musty odors through supply registers.
- Failed access panel seals reintroducing attic contamination. After any duct cleaning, unsealed or poorly sealed access panels allow humid, dusty attic air to re-enter the system. We see this repeatedly in Alamo Heights homes where previous services skipped this final step, undoing the cleaning within months.

FAQs — Air Duct Cleaning in Alamo Heights
Alamo Heights homes were built before modern sealed-duct standards existed, and most have had piecemeal HVAC modifications rather than full system replacements. Original sheet-metal trunks with retrofitted flex-duct extensions create ledges and dead-leg sections where caliche dust and cedar pollen accumulate permanently — configurations that simply don’t exist in newer construction with continuous, sealed duct runs. Call (866) 769-1699 and we’ll show you exactly what your system contains.
Cedar Fever peaks from December through February, and we see our highest call volume in January when residents realize their indoor pollen load isn’t improving despite closed windows. Scheduling cleaning in late fall — before peak season — prevents pollen accumulation from reaching symptomatic levels, though we’re available throughout the winter for urgent requests. Call (866) 769-1699 to book ahead of the rush.
Duct cleaning often resolves musty odors when the source is mold or organic debris inside the duct pathway, which is common in Alamo Heights homes with unsealed flex-duct additions in humid attics. However, if the odor originates from HVAC condensate pans, building envelope moisture, or other sources, cleaning alone won’t solve it — our video inspection identifies the actual cause before we commit to service. Call (866) 769-1699 for a diagnostic visit.
Yes — video inspection is standard procedure for every Alamo Heights job we perform, included at no additional cost with full system cleaning. We consider it essential given the prevalence of retrofitted duct configurations and dead-leg sections in 78209 housing stock. Standalone video inspections are also available for $120–$180. Call (866) 769-1699 to schedule.
Yes — filters capture particulate at the return grille, but they don’t address material already deposited inside duct trunk lines, plenums, or dead-leg sections. In Alamo Heights specifically, cedar pollen and caliche dust enter through window and door gaps during shoulder months, then recirculate from duct deposits for months after outdoor levels drop. Monthly filter changes are necessary but insufficient for complete allergen control in these older systems. Call (866) 769-1699 for an inspection and exact quote — estimates are free.
