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.

AfterCarrier Air Duct Cleaning in San Antonio, CA | Hollis Air Duct Cleaning
Carrier air duct cleaning in San Antonio runs between $425 and $680 for a full single-system home, depending on square footage, the number of returns, and how much caliche dust and live oak pollen has packed into the runs. We’re an independent Carrier service provider, not a Carrier-authorized shop, and we’ve been cleaning and repairing Carrier-connected duct systems across San Antonio since 2004. What makes our Carrier work different here is simple: we know what this city’s dust does to Carrier equipment because we pull it apart daily. Call (361) 326-5060 for a written estimate before any work begins. If you need Carrier sales & service, start with a call.
Why San Antonio Residents Choose Us for Carrier Service
Carrier builds good equipment. The Infinity variable-speed air handlers and Performance series furnaces are solid machines, but they live or die by the ductwork attached to them. In our San Antonio service area, that ductwork is often 30 to 60 years old in the 1950s-through-1980s ranch homes that fill neighborhoods like Alamo Heights and Monte Vista. Roy Castellanos, our owner, came up through the sheet metal and air conditioning program at Los Angeles Trade-Technical College and spent years doing hands-on duct work before starting Hollis Air Duct Cleaning. That background means we treat a Carrier system as one connected machine, not a furnace in one corner and some flex duct as an afterthought.
We run Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, not hardware-store gear. Every technician is background-checked and uniformed. The price is written down before we touch anything. And every job carries the 365-Day Done Right Promise: if the work fails within a year, we come back at no charge, including a free second visit. That’s The Garrison Standard, and it’s why our San Antonio customers stay with us. Serving San Antonio service area is what we do.
Common Carrier Air Duct Cleaning Problems We Solve in San Antonio
- Caliche dust choking variable-speed blowers. Carrier Infinity and Performance air handlers pull fine caliche grit past standard filters. The dust coats the blower wheel and evaporator coil, airflow drops, and the system runs longer to hit the thermostat. San Antonio’s almost year-round runtime makes this worse than in cooler cities. We clean the blower wheel, the coil, and the cabinet interior to restore airflow.
- Musty odors from biofilm on cased coils. San Antonio’s humid summers, with average highs in the 90s, keep Carrier cased coils damp for months. Biofilm and mold spores build up and push a musty smell through the supply registers. We clean the coil with the right agents and address the moisture source so the smell doesn’t return in three weeks.
- Sagging flex duct on Carrier plenums in ranch homes. Original flexible ductwork in 1950s-1980s San Antonio ranch homes sags and kinks over time. Low-velocity pockets form, and live oak pollen settles there. Cleaning helps, but repairing or replacing the flex is often the real fix. We do both.
- Return-side leaks pulling attic air and rodent debris. Older Carrier systems in San Antonio leak at the return connection. That draws hot attic air, dust, and sometimes rodent nesting material into the cabinet. The coil fouls faster, and the cabinet can corrode. We seal the leaks with mastic and clean what got pulled in.
- Rodent intrusion in older neighborhoods. In Alamo Heights and Monte Vista, we regularly find original Carrier-connected ductwork with rodent nests inside. Warm weather extends the activity season. We treat those runs as contamination zones, not just dust jobs: remove the damaged flex, seal the plenum, and reinstall insulated flex duct.
Carrier Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio’s heavy caliche dust and live oak pollen coat duct systems differently than in other Texas cities, and the city’s pre-1990s neighborhoods often have flex duct runs that sag and collect this debris. Caliche is a fine, powdery limestone dust that hangs in the air and settles into every low-velocity pocket in a duct system. Live oak pollen, which peaks in spring, is sticky and clings to the inside of flex duct walls. For a Carrier variable-speed air handler, this is a compounding problem: the ECM blower ramps up to maintain airflow, pulls harder on the return, and drags more of that dust through the filter and onto the blower wheel. Air Duct Cleaning in San Antonio isn’t an upsell; it’s the difference between a 12-year blower motor and a 7-year one. In Alamo Heights, our crew pulled a Carrier Performance air handler apart on a 1960s ranch home and found the return flex duct collapsed and packed with rodent nesting material and live oak pollen. We removed the contaminated flex run, sealed the plenum with mastic, cleaned the evaporator coil and blower wheel, and reinstalled new insulated flex duct. The homeowner’s airflow readings returned to spec and the musty odor at the registers cleared.
Carrier Models & Products We Service in San Antonio
We work on Carrier Performance series air handlers and furnaces, Infinity series variable-speed air handlers, Comfort series packaged units and split systems, and 24ACC6 / 24ACC7 style condensers paired with matching indoor air handlers. The cleaning approach differs by model: variable-speed blowers need the wheel pulled and washed, while single-speed Comfort blowers can often be cleaned in place with less labor. We stock or source genuine Carrier OEM replacement parts where fit and warranty continuity matter, and we use quality aftermarket equivalents for non-critical items like flex duct, mastic, and vent caps. When a Carrier coil or heat exchanger is fouled or failing, we give an honest repair-versus-replace assessment rather than defaulting to replacement.
Carrier Service Pricing in San Antonio
Full-system air duct cleaning on a Carrier-equipped San Antonio home typically runs $425-$680 as a flat whole-system price. Larger homes with multiple returns or heavily contaminated runs can push toward $800. Evaporator coil cleaning adds $150-$250 when done as part of the job, and flex duct repair or replacement runs $12-$18 per linear foot installed. What drives the cost: number of returns, duct length, access difficulty, and contamination level. A written estimate is free, and the price on that estimate is the price you pay. No per-vent pricing, no bait-and-switch. Call (361) 326-5060 for an exact quote.

FAQs – Carrier Air Duct Cleaning in San Antonio
Does my Carrier system need duct cleaning more often because I live in San Antonio? Yes. San Antonio’s caliche dust, live oak pollen, and nearly year-round runtime mean Carrier systems accumulate debris faster than in cooler or less dusty cities. Most homes in San Antonio need cleaning every 2 to 3 years, and older ranch homes with original flex duct may need annual attention. Call (361) 326-5060 and we’ll tell you what your system actually needs.
Will cleaning my Carrier evaporator coil void my Carrier warranty? No. Coil cleaning performed by a trained technician using approved methods does not void a Carrier warranty. What voids warranties is neglect, improper installation, or unauthorized modifications. We document our work and use the right cleaning agents for aluminum and copper coils.
My Carrier Infinity system smells musty when it starts – is that a duct problem? It’s usually a coil problem. San Antonio’s humid summers keep Carrier cased coils damp, and biofilm grows on the coil surface. The smell travels through the ducts when the blower starts. We clean the coil and inspect the drain pan and line, then check the ductwork for any moisture source.
Why does my Carrier system in an older San Antonio ranch home have weak airflow? In most cases, the original flex duct connected to the Carrier plenum has sagged, kinked, or collapsed over decades. Caliche dust settles in the low spots and further restricts airflow. We inspect the runs, repair or replace what’s bad, and clean the blower wheel if it’s been straining.
Do you use Carrier OEM parts for duct and coil work? For parts where fit and warranty continuity matter, we stock or source genuine Carrier OEM replacements. For non-critical items like flex duct, mastic, and vent caps, we use quality aftermarket equivalents that perform as well and cost less. We’ll show you the difference before any work starts.
