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.
Air Duct Cleaning Company in Alamo Heights, TX
Air duct cleaning in Alamo Heights runs $350 – $650 for most single-system homes, with dryer vent cleaning typically $120 – $180 and duct sealing ranging $800 – $2,400 depending on system size and accessibility. What drives the real cost isn’t the square footage on a flyer; it’s the age of the house, the condition of original ductwork, and whether technicians need to work around protected live oaks to reach roof vents. At Hollis Air Duct Cleaning, we price every Alamo Heights job in writing before we start, backed by our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Dispatch and scheduling for Alamo Heights are coordinated from our San Antonio office, with crews serving the city locally. We’ve built our pricing and process around the realities of this market: historic homes with plaster ceilings and pier-and-beam foundations, strict tree preservation ordinances that limit roof access, and HVAC systems that run hard through eight months of humid heat.
Why Alamo Heights Homes Are Different
Alamo Heights has one of Texas’s oldest and most strictly enforced tree preservation ordinances. Mature live oaks and pecans canopy directly over historic roofs, which means air duct cleaning here is as much about clearing roof-level debris, pollen, and acorn mast from vents and intakes as it is about cleaning the ducts themselves. Technicians must often work around protected trees and navigate narrow driveway access on tight lots, constraints that don’t apply to neighboring San Antonio.
Much of the housing stock dates to the 1920s – 1950s: pier-and-beam foundations, plaster walls, and small-diameter ductwork or original gravity systems. Renovations left mismatched duct runs, and many houses still have attic ducts undersized for modern HVAC equipment. The original single-return systems common in 1930s – 40s bungalows draw air through long, narrow chases hidden above plaster ceilings, and we regularly find those chases shared with decommissioned floor-furnace flues.
The humid subtropical climate keeps HVAC running nearly year-round, accelerating dust and microbial buildup. Spring pollen from live oaks and cedars, combined with occasional heavy rains, pushes moisture and debris into vent openings that newer suburbs simply don’t face.
Our Main Alamo Heights Services
Alamo Heights homeowners call us most often for these three jobs, each handled with equipment from Rotobrush, Nikro, and Abatement Technologies and priced in writing before work begins.
Air Duct Cleaning in Alamo Heights
We clean supply and return ducts with a rotary brush system and negative-air method, pulling loosened debris out of the house rather than redistributing it. In Alamo Heights, this means accounting for plaster ceiling chases, small-diameter original ductwork, and roof vents partially blocked by tree debris. We inspect with a camera before and after so you see what came out. Air Duct Cleaning in Alamo Heights covers full-system pricing and what to expect on older homes.

Dryer Vent Cleaning in Alamo Heights
Dryer vent cleaning removes lint buildup from the transition duct through the exterior cap, reducing fire risk and improving dry times. In Alamo Heights, long vent runs through pier-and-beam crawl spaces and exterior caps tucked under eaves or behind mature trees require specialized tools and careful routing. We clear the full run and verify airflow with a meter. Dryer Vent Cleaning in Alamo Heights has full details on multi-story and historic-home configurations.

Duct Sealing in Alamo Heights
Duct sealing closes leaks in supply and return runs with mastic and mechanical fasteners, or aerosol sealant for inaccessible attic ducts. Alamo Heights homes often have decades of partial repairs, mismatched materials, and undersized returns that leak conditioned air into attics and crawl spaces. We test with a duct blaster, seal, and verify improvement. Duct Sealing in Alamo Heights explains the process for gravity-system conversions and historic-home retrofits.
