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.

AfterFast, Reliable Air Duct Cleaning Across Alamo Heights
Air duct cleaning in Alamo Heights typically runs $350 – $650 for a whole-home system, and most jobs are scheduled within a few days of your call. If you’re noticing dust settling on furniture hours after dusting, smelling must when the AC kicks on, or watching your energy bill climb through another long South Texas summer, your ductwork is likely circulating more than just cooled air. Hollis Air Duct Cleaning has served Alamo Heights since 2004, dispatching from our San Antonio office with crews who know the tight lots off Broadway, the narrow driveways near the Quarry, and the specific headaches that come with cleaning ducts in homes built when Harry Truman was president. Call us at (361) 326-5060 for a free written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Alamo Heights’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Alamo Heights one scheduled window at a time. Our technicians arrive uniformed, background-checked, and inside the quoted arrival window, not three hours later with an apology. The Garrison Code governs how we behave on every job: price in writing before touching equipment, complete the work by the book, leave the site clean.
Alamo Heights homeowners aren’t shy about telling us what they think. Reviews from local customers consistently mention the same things: the technician explained what he found, showed before-and-after photos of the actual ducts, and the final invoice matched the written quote. No one likes surprises in their hallway.
Response time matters here because your HVAC system doesn’t take days off. Calls to our Alamo Heights line are answered by a live person, 24 hours a day, 7 days a week. No voicemail loops, no “we’ll call you back Monday.” Scheduling is coordinated from our San Antonio office, and crews serve Alamo Heights locally, so we understand traffic patterns on Nacogdoches Road and the access challenges around the Alamo Quarry Market area.
Local knowledge separates a technician from a visitor with a vacuum. We know which Alamo Heights blocks have 1920s pier-and-beam homes with original gravity systems, which 1940s bungalows hide return chases shared with decommissioned floor furnace flues, and why the city’s strict tree preservation ordinance means roof-level intakes often collect acorn mast and live oak pollen that newer suburbs simply don’t face. That context changes how we clean your ducts.
Air Duct Cleaning Services in Alamo Heights
Air Duct Cleaning Services in Alamo Heights cover the full removal of accumulated dust, pollen, debris, and microbial buildup from your home’s supply and return ductwork, registers, and grilles. Most Alamo Heights homeowners schedule this every three to five years, though homes with original 1920s – 1950s ductwork, year-round HVAC use, or mature oak canopy overhead often need attention sooner. A typical residential system in Alamo Heights runs $350 – $550; larger homes or systems with heavy contamination range $450 – $650.
Residential System Cleaning
We clean the full duct network in your home using a Rotobrush rotary brush system that loosens adhered debris, paired with a Nikro negative-air machine that pulls it out before it escapes into your living space. In Alamo Heights’s older homes, we’re especially careful around small-diameter original ducts and plaster ceiling chases that newer equipment can damage if handled roughly.
Video Inspection and Documentation
Before we start and after we finish, we run a camera through your main trunk lines. You’ll see exactly what was in there and exactly what came out. No guesswork, no trust-me claims. The footage belongs to you, and we keep copies on file in case questions arise later under our 365-Day Done Right Promise.

HVAC Duct Cleaning in Alamo Heights
HVAC Duct Cleaning in Alamo Heights addresses the entire forced-air system: ducts, coils, blower assembly, and plenum, not just the visible vents. Because Alamo Heights sits in a humid subtropical climate with HVAC systems running nearly year-round, dust and moisture combine inside dark ductwork in ways that accelerate microbial growth and restrict airflow. A typical HVAC duct cleaning in Alamo Heights costs $400 – $600 for a standard residential system; commercial or heavily contaminated systems can reach $700 – $900.
Coil and Blower Cleaning
Your evaporator coil and blower wheel collect the same debris your ducts do, and dirty coils force your compressor to work harder, shortening equipment life in a climate where it already runs overtime. We clean these components as part of a full HVAC duct cleaning, using tools and techniques that match the equipment manufacturer’s specifications.
Supply and Return Line Separation
Many Alamo Heights homes, especially pre-war bungalows near Austin Highway, have supply and return lines that were modified during decades of partial renovations. We identify and clean each separately, ensuring negative-air pressure is applied correctly and no section is bypassed because someone drywalled over an access point in 1987.
Trusted Brands We Service in Alamo Heights
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use in hospitals and schools, not hardware-store attachments. For Alamo Heights homeowners, this means we stock filters, replacement media, and compatible components locally, so if your cleaning reveals a failing filter housing or degraded flex duct, we can address it during the same visit rather than ordering parts and rescheduling. We also handle Dryer Vent Cleaning in Alamo Heights and Duct Sealing in Alamo Heights using compatible equipment and the same written-pricing standard.
Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Oak pollen and acorn mast in roof-level intakes. Alamo Heights’s tree preservation ordinance keeps massive live oaks and pecans canopied directly over historic roofs, so vent openings collect seasonal debris that suburban homes with cleared lots never see. We regularly clear packed pollen and mast from intake screens during spring cleanings.
- Undersized attic ducts mismatched to modern HVAC equipment. Many Alamo Heights homes received partial duct upgrades during renovations, leaving 1950s trunk lines connected to new air handlers that push more air than the old metal can handle. Cleaning reveals separations, collapsed flex runs, and pressure imbalances that explain why the back bedroom never cools.
- Return chases shared with decommissioned floor furnace flues. In 1930s – 40s bungalows near Terrell Road and Castano Avenue, we frequently find that the central hallway return chase was originally built around a floor furnace flue. The flue is long gone, but the chase still draws return air past decades of soot and debris that standard cleaning misses without proper access.
- Moisture intrusion from heavy rains and humid summers. Alamo Heights’s occasional storm deluges and persistent humidity drive moisture into attic ducts and plenums, especially where original metal has rusted through or modern flex duct has pulled loose. We document moisture damage during video inspection and can coordinate repair through our Air Duct Cleaning team before microbial problems establish.
Pricing for Air Duct Cleaning in Alamo Heights, TX
We publish our ranges because we respect your time and we don’t play the bait-and-switch game that gives this trade a bad name. A typical residential air duct cleaning in Alamo Heights runs $350 – $550 for a whole-home system. Larger homes above 3,500 square feet, systems with heavy contamination requiring multiple passes, or homes with original small-diameter ductwork that demands specialized tooling can reach $450 – $650. Commercial duct cleaning in Alamo Heights starts around $600 and scales with system complexity.
What moves the price: square footage, number of registers and returns, accessibility (crawl spaces and attic chases take longer), and contamination level. We do not charge per vent. We quote one flat price per system, agreed in writing before work begins, and that number does not change when the technician arrives. Every estimate is free. Call (361) 326-5060 to schedule yours.

FAQs About Air Duct Cleaning in Alamo Heights
Most Alamo Heights appointments are scheduled within two to five business days, and we arrive inside the quoted window. Call (361) 326-5060 to check current availability; estimates are free and can often be done same-day if a crew is already in the Broadway or Nacogdoches Road area.
Yes, we clean ducts throughout Alamo Heights, from the historic blocks near Austin Highway and Broadway down to the Quarry area and the residential streets off Castano Avenue and Terrell Road. Tight lots and narrow driveway access are familiar challenges here, not exceptions.
We do not classify duct cleaning as an emergency service; it is a scheduled maintenance job. However, our phones are answered by a live person 24/7, so you can always reach us to describe your situation, schedule promptly, and get guidance on whether your issue requires immediate HVAC attention or can wait for a standard cleaning appointment.
Prices are comparable, though Alamo Heights’s older housing stock and strict tree preservation ordinance sometimes add complexity. Homes with original 1920s – 1950s ductwork, narrow access, or heavy roof-level debris from mature oak canopy may require additional time or specialized tooling, which we account for in the written quote before work begins.
Every Hollis job in Alamo Heights is backed by our 365-Day Done Right Promise in writing. If the work fails within a full year, we return and make it right at no charge, including a free second visit.
