Fast, Reliable Air Duct Cleaning Across Alamo Heights
Air duct cleaning in Alamo Heights typically runs $450 – $1,400 for a full system, depending on how many HVAC units your home has and how accessible the ductwork is. Most older homes here need more time than the national average because of tight attic spaces and original galvanized ducts. Our crews know the streets off Broadway, the pier-and-beam foundations near Cambridge Oval, and the mid-century layouts that make Alamo Heights ductwork its own animal. Call (254) 347-3897 and we’ll give you a real number before anyone steps foot in your attic.
Why Cardinal Air Duct San Antonio Is Alamo Heights’s Preferred Air Duct Cleaning Company
We’re part of the Relay Home Co. family, founded in 2005, and every Alamo Heights job runs on The Relay Standard: a live trackable arrival time, before-and-after photo proof, and a written price handed to you before a single duct is touched. That matters in a city where a lot of the work happens in crawl spaces and attics you’ll never personally inspect. Omar Haddad leads our crews, and he’s built the team around one rule: if you can’t see it, we show it to you.
Our technicians are background-checked, uniformed, and trained on the specific failure modes of Alamo Heights homes. That means we don’t jam aggressive rotary brushes into brittle 1950s foil-wrapped ducts. We adjust the tool to the house. The result is cleaner air without torn insulation, shredded duct lining, or a bigger repair bill than you signed up for. Our Air Duct Cleaning team documents every register with camera inspection, so you see what we saw.

Ductwork Cleaning in Alamo Heights
Ductwork cleaning in Alamo Heights is a different job than what a newer subdivision requires. Many homes here were built between the 1920s and 1960s, with original galvanized steel ducts that have spent decades collecting dust, pollen, and humidity-driven microbial growth. In a 1949 home off Broadway near the old Alamo Heights swimming pool, our crew found original supply and return ducts wrapped in crumbling 1950s foil insulation. We used negative pressure and HEPA filtration to contain the debris, then performed source removal on three separate systems before documenting the finished registers with camera inspection. The homeowner finally understood why per-system pricing mattered.
What this work costs in Alamo Heights: a single-system ductwork cleaning generally runs $450 – $750, while a two-to-three system home lands between $900 and $1,400. The spread depends on access difficulty and whether we’re navigating pier-and-beam crawl spaces or tight attic chases.
Source Removal Method
We use negative-pressure extraction, which means the loosened debris goes straight into a Nikro HEPA vacuum, not back into your living room. Rotobrush rotary tools agitate the duct walls, and Abatement Technologies containment units seal off the work area. It’s the approach older Alamo Heights homes need, because dust here is often caked onto decades-old duct interiors.
Three-System Homes and Long Runs
Many larger Alamo Heights properties run three independent HVAC systems, each with its own supply and return network. Quoting a flat whole-house price without knowing that leads to skipped duct runs and half-finished work. We price per system, which is the only honest way to handle a house where the east wing doesn’t share ductwork with the west wing.
Air Duct Inspection in Alamo Heights
Air duct inspection in Alamo Heights is the step that answers the question, “What’s actually in there?” before any cleaning starts. We run a camera through your supply and return ducts, look for crushed sections, rust on galvanized steel, failing foil wrap, and any moisture that shouldn’t be there. Given how many Alamo Heights homes sit on pier-and-beam foundations with duct runs under the floor, a visual inspection often reveals gaps and disconnections you’d never catch from the register.
A standalone camera inspection in Alamo Heights costs $150 – $300, and that fee is waived when you proceed with a full cleaning on the same visit. For historical properties where preservation rules limit what can be modified, the inspection report also gives you documentation to show contractors, architects, or city code officials.
Camera Documentation
You get still images and video of the register openings, inside the main trunk lines, and any trouble spots we flag. No vague “it was dirty” summary; you see the before and after. That documentation is part of every job, not an add-on.
Preservation-Sensitive Inspection
Alamo Heights has strict building codes and historical preservation rules, which means duct modifications often need to be minimally invasive. Our inspection identifies what can be cleaned in place, what needs custom sealing, and what should be left alone until you’ve talked with the city or your preservation consultant.
Trusted Brands We Service in Alamo Heights
We work on systems paired with Aprilaire filtration products, Honeywell controls, Guardsman components, and whatever brand your existing ductwork happens to be. For Alamo Heights homeowners, that means we show up carrying the filters, sealants, and replacement parts that match 1950s-to-1960s equipment as often as modern setups. You won’t wait a week while we order a part from a warehouse; most replacements for common Alamo Heights systems are on the truck. Rotobrush and Nikro equipment handle the cleaning side, and Abatement Technologies containment gear keeps the work area sealed.
Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Crumbling 1950s foil insulation inside attics. Original foil wrap from the mid-century breaks apart the moment it’s touched. We use containment and HEPA capture so that debris never spreads through the house.
- Undersized galvanized ducts in pier-and-beam homes. These older systems often run too small for modern AC loads, which means they clog faster. Cleaning helps, but a full fix often requires custom sealing work in tight crawl spaces.
- Rapid microbial growth from long cooling seasons. Alamo Heights humidity and air conditioning that runs March through October create a perfect environment for buildup on duct interiors. Cleaning once every 3 – 5 years makes a measurable difference in airflow and indoor air quality.
- Multiple systems that never all get cleaned. A home with three HVAC units needs three separate cleanings, not a single crew working for an hour and calling it done. We price per system so none of them get skipped.

FAQs About Air Duct Cleaning in Alamo Heights
Pier-and-beam foundations put duct runs under the floor in crawl spaces, so cleaning requires accessing registers from both above and below, which takes longer than slab homes. We routinely work in Alamo Heights crawl spaces and build that access time into the per-system price so there’s no surprise upcharge when the crew gets under the house. Call (254) 347-3897 for a quote specific to your foundation type.
The hot, humid air that sits over Alamo Heights from March through October pushes moisture into duct interiors, where it mixes with dust to form a stubborn residue that reduces airflow and feeds microbial growth. Drier parts of the metro don’t see the same buildup rate, so Alamo Heights homes often need cleaning more frequently to maintain the same air quality. If your registers smell musty when the AC kicks on, call us and we’ll inspect it.
We use lower-torque rotary agitation and HEPA negative-pressure capture rather than aggressive brushing that can tear thin, corroded galvanized steel. The tool speed is matched to the duct condition, which is why we inspect first and clean second. This approach prevents the kind of damage that turns a $600 cleaning into a $4,000 duct replacement.
No, three separate systems cost more than one larger system because each HVAC unit has its own supply and return duct network that has to be accessed individually. A three-system Alamo Heights home typically runs $1,100 – $1,400, while a single-system home is $450 – $750. We price per system, so you know exactly what you’re paying for before work starts, and no duct run gets skipped.
You should get before-and-after camera photos of the registers and trunk lines, plus a written summary of what was cleaned, what condition the ducts were in, and any issues we flagged for follow-up. That documentation is part of every Cardinal job and is especially useful in Alamo Heights if you’re dealing with historical preservation approvals or documenting maintenance for resale. Call (254) 347-3897 and we’ll walk you through exactly what the report includes.
