Fast, Reliable Air Duct Cleaning Across San Antonio
Air duct cleaning in San Antonio runs $340 to $560 for a standard single-system home, and most jobs take four to six hours from setup to final camera walkthrough. That price covers a full source-removal clean of supply and return ducts, the air handler interior, and blower assembly. If you’re on an unpaved road outside the city limits, near Poteet or Elmendorf, expect the higher end of that range because the dust load is genuinely heavier. Call us at (254) 347-3897 and we’ll give you a written price before any work starts, not after the van is parked in your driveway.
We work throughout San Antonio, from the pier-and-beam bungalows inside Loop 410 to the newer subdivisions pushing west past Alamo Ranch. Local knowledge matters here because the dust in a Jefferson neighborhood crawl space is not the same dust in a Helotes ranch house. Omar Haddad runs our San Antonio crew, and he will tell you straight: the wrong cleaning method on the wrong house just stirs up allergens and makes things worse.
Why Cardinal Air Duct San Antonio Is San Antonio’s Preferred Air Duct Cleaning Company
We are not the cheapest quote you will get in San Antonio, and we won’t pretend to be. What we offer is the Air Duct Cleaning standard that actually holds up when you inspect the work afterward. Every job comes with before-and-after photos, a live arrival window you can track from your phone, and a digital invoice payable by link. This is The Relay Standard, and it applies to every single booking without exception.
Omar Haddad and his technicians are background-checked, uniformed, and trained on professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. That last one matters if you have allergies: Abatement Technologies containment units create true negative pressure, so loosened debris goes into the HEPA filter rather than back into your living room. We also carry Honeywell and Aprilaire filtration products if your system needs an upgrade while we’re in there.
The 365-Day Done Right Promise covers every job we do in San Antonio. If the work isn’t right within a full year, we return and correct it at no charge. No fine print, no “that’s not covered” phone calls. A live person answers our phones 24/7, so you won’t leave a voicemail and hope for a callback next Tuesday.

Air Duct Cleaning Services in San Antonio
Air Duct Cleaning Services in San Antonio means removing the accumulated dust, pollen, pet dander, and construction debris from every supply and return duct in your HVAC system. For most San Antonio homes, a standard clean runs $340 to $560 depending on system size and accessibility. You need this when vents blow visible dust, rooms smell musty when the AC kicks on, or someone in the house has year-round allergy symptoms that worsen indoors.
Full System Cleaning
A full system clean means we don’t just vacuum the ducts and call it done. We open the air handler, clean the evaporator coil, blower wheel, and blower housing. The reason is simple: if the blower is packed with caliche dust, it’ll just blow that grit back into freshly cleaned ducts within a week.
Video Inspection
Every job starts with a camera inspection of your supply and return runs. In older San Antonio homes, especially pier-and-beam construction, we’re looking for sagged flex duct, rodent damage, and collapsed sections under the floor. You see the same footage we see, and the price we quote covers what the camera actually found, not what we guessed before showing up.

HVAC Duct Cleaning in San Antonio
HVAC Duct Cleaning in San Antonio is more aggressive than a standard duct cleaning because it includes the furnace or air handler cabinet, coil, and blower assembly, not just the duct runs themselves. A full HVAC duct cleaning in San Antonio typically costs $380 to $560. This is the service you want when the system hasn’t been touched in five or more years, or when you’re in a rural property near unpaved roads where dust infiltrates the return plenum and coats the blower motor.
Return Duct Cleaning
Return ducts pull air from your home into the system, and in San Antonio they’re usually the dirtiest part of the job. On rural properties especially, return plenums collect a gritty paste of caliche dust and cedar pollen. We clean these with HEPA-filtered negative pressure extraction, meaning the debris goes into the vacuum, not your air.
Supply Duct Cleaning
Supply ducts deliver conditioned air back into your rooms. In homes built in the 1970s and 1980s around San Antonio, original flex duct often sags between joists and creates pockets where dust accumulates for years. Our Nikro HEPA vacuums and Rotobrush agitation tools break that material loose and remove it without tearing the flex liner.
Trusted Brands We Service in San Antonio
We clean ducts on every major system in San Antonio, from original Trane and Carrier units in 1990s tract homes to high-efficiency Lennox and Daikin setups going into new construction on the far west side. Our technicians stock common filters and access panels locally for San Antonio jobs, which means fewer return trips waiting on parts. Whether your system runs Honeywell media cabinets or Aprilaire filtration, we service it and can recommend the right filter for your home’s specific dust load.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Cedar pollen packed into duct seams and boots. San Antonio’s annual cedar fever season from Ashe juniper isn’t just an outdoor nuisance. That fine pollen gets pulled into return ducts and settles where the duct meets the boot, forming an allergenic layer that kicks up every time the AC cycles.
- Caliche dust coating the blower and evaporator coil. The white limestone dust from local construction and unpaved roads is finer than typical household dust. It cakes onto blower wheels and coils, forcing longer AC runtimes and higher energy bills, and it’s abrasive enough to accelerate blower bearing wear.
- Rat-chewed flex duct under pier-and-beam homes. In older San Antonio neighborhoods like Jefferson and Beacon Hill, supply ducts under the floor get chewed by rodents and collapse over time. A superficial clean won’t fix a collapsed duct, which is why we camera-inspect every run before quoting.
- Saharan dust grit in trunk lines on the south and east sides. When Saharan dust events blow through Texas, that fine grit settles into return plenums and trunk lines. It’s denser than normal house dust and requires HEPA extraction to remove, not a brush-only pass.

AfterPricing for Air Duct Cleaning in San Antonio, TX
Here are the honest numbers for San Antonio’s market. A standard residential air duct cleaning for a single HVAC system runs $340 to $560. A two-system home, common in newer San Antonio builds with a separate unit upstairs, runs $520 to $780. Commercial duct cleaning in small offices and retail spaces starts around $450 and scales with square footage and vent count. Video inspection is always included, before and after, at no extra charge. The factors that push you toward the higher end: long duct runs in pier-and-beam crawl spaces, heavy rural dust loading, inaccessible air handlers in attics, or systems that haven’t been cleaned in over ten years.

FAQs About Air Duct Cleaning in San Antonio
Every 2 to 3 years is realistic for rural properties on unpaved roads. The fine caliche dust and pollen from open land infiltrates return ducts and coats the blower faster than in city neighborhoods. If you run your AC year-round, which most San Antonio-area homes do, that dust cycles constantly and builds up quicker than the 5 to 7 year interval you’d hear for a typical urban home. Call (254) 347-3897 and we can inspect your system and give you a realistic timeline for your specific property.
Unfortunately, yes, it’s common in older pier-and-beam homes in San Antonio. The white dust is caliche from the lime-rich local soil, and the musty smell usually comes from moisture in the crawl space mixing with dust and rodent debris inside sagging flex duct. The fix is a full source-removal clean with re-supporting and sealing of the duct runs, not just a vacuum pass. This is exactly the kind of job our San Antonio crew does repeatedly. Call us for an inspection and we will show you what the camera sees under your floor.
It absolutely affects your ducts. Ashe juniper pollen from the Hill Country is fine enough to pass through most standard return filters, especially if the filter is not a high-MERV media type. Once inside the system, it settles in trunk lines and boots, then re-circulates every time the AC runs. That means cedar allergy symptoms can persist indoors long after the outdoor pollen count drops. A proper HEPA-filtered duct cleaning removes that reservoir; a brush-only clean does not. Our Nikro HEPA vacuums capture the pollen rather than pushing it around.
New construction ductwork in San Antonio is almost always contaminated with drywall dust, sawdust, paint overspray, and general construction debris because the HVAC system runs during the build before returns are sealed. Builders rarely clean ducts before handoff, even in tight, high-efficiency homes. A post-construction duct cleaning in a new Alamo Ranch or west-side build typically runs $340 to $520 for a single system and makes an immediate difference in indoor air quality. Call us and mention it’s a new build; we’ll walk you through what’s involved.
No, dryer vent cleaning is a separate service from air duct cleaning, and we do both. A long attic dryer vent run in an older San Antonio ranch collects lint at bends and horizontal sections, which is a fire hazard and a drying-efficiency problem. The good news is we can clean both the dryer vent and the HVAC ducts in the same visit. Tell us about the layout when you call (254) 347-3897 and we’ll factor the attic access into your written quote.
