Air Duct Cleaning Company in Alamo Heights, TX
Air duct cleaning in Alamo Heights runs $350 to $650 for most single-family homes, though the city’s older housing stock often pushes that higher once we see what’s inside the attic. We’re Cardinal Air Duct San Antonio, part of the Relay Home Co. family founded in 2005, and we specialize in homes built between the 1920s and 1960s. That matters here because Alamo Heights ducts are rarely a quick vacuum job. They’re original galvanized steel, they’re wrapped in crumbling foil insulation, and they sit in attics too tight for standard equipment. Call (254) 347-3897 and we’ll give you a written price before any work starts.
Why Alamo Heights Homes Are Different
Alamo Heights runs hot from March through October, and the humidity doesn’t take a break either. AC systems here work harder and longer than in most of Texas, which means dust, pollen, and moisture cycle through the ductwork at a rate that surprises homeowners. High outdoor pollen settles in the return, humidity feeds microbial growth inside the plenum, and by late summer the supply registers are recirculating whatever built up since spring.
The housing stock makes it more complicated. Many Alamo Heights homes sit on pier-and-beam foundations with undersized ducts squeezed into small attic spaces. The city’s building codes and historical preservation rules demand minimally invasive modifications, so you can’t just cut open a chase and run new lines wherever you want. In the older neighborhoods north of Broadway, we regularly see ducts wrapped in thin foil insulation from the 1950s that crumbles on contact. That’s why we run Abatement Technologies containment units on these jobs: negative-pressure extraction, meaning loosened debris goes straight into the vacuum instead of drifting back into your living room. Alamo Heights work rewards patience and the right equipment. That’s what we bring.
Styles & brands we work with
Our Main Alamo Heights Services
Most Alamo Heights homeowners call us for one of three things: a dryer vent that isn’t moving air, a full air duct cleaning, or an HVAC cleaning that gets the coils and blower back to spec. Each has its own page below.
Dryer Vent Cleaning in Alamo Heights
Older Alamo Heights laundry rooms often vent through short, awkward runs with multiple elbows, and over the years lint packs into those bends until airflow drops. We inspect the run, clean it with professional equipment, and confirm proper termination outside. If the vent is wrapped in that old foil material or runs through a tight pier-and-beam space, we take extra care not to disturb what’s around it. Lint fires are a real risk, and this is one job where professional equipment makes a measurable difference. See Dryer Vent Cleaning in Alamo Heights for full pricing and what we check.
Air Duct Cleaning in Alamo Heights
Original galvanized ducts from the 1940s and 1950s are standard here, and they corrode from the inside after decades of humid San Antonio-adjacent air moving through them. We run a Rotobrush system through the supply and return, then pull everything out with Nikro HEPA-rated vacuums. In Alamo Heights attics, the challenge is access: we often work in spaces where a grown adult has to move on hands and knees. That’s what the HEPA extraction is for. Nothing we knock loose goes back into your home. Read Air Duct Cleaning in Alamo Heights for photos of what we typically find and the exact price ranges.
HVAC Cleaning in Alamo Heights
HVAC cleaning is more than the ducts. It’s the evaporator coil, the blower wheel, the condensate pan, and the surfaces inside the air handler. In Alamo Heights, where systems run heavily for eight months a year, those components cake up fast with pollen and dust. A dirty coil raises your electric bill and shortens the life of the compressor. We clean the full system with professional equipment and check the drain line while we’re in there. HVAC Cleaning in Alamo Heights covers the full scope and what it costs.

FAQs About Air Duct Cleaning Company in Alamo Heights
We schedule most Alamo Heights jobs within two business days. We do not promise same-day arrival because duct cleaning is a scheduled job, not an emergency call. When you book, you get a live arrival window you can track from your phone. That’s the Relay Standard, and every booking includes it.
Most cleanings don’t require a permit. If we’re doing duct replacement or modification, the city’s stricter building codes may require one, and we coordinate that on the back end. The work itself is always minimally invasive, which matters most in areas under historical preservation review. Call (254) 347-3897 for an exact read on your home.
No. On Alamo Heights homes with fragile duct wrap, we run negative-pressure containment the entire time. That means the air in the duct system stays under vacuum, and loosened debris exits through the HEPA filter. We also protect furniture and flooring in the room where we set up. If you have questions before we arrive, call (254) 347-3897.
