Air Duct Cleaning Cost Breakdown (2026)
Here’s what you can expect to pay in the San Antonio market right now, broken down by home size and job scope. These ranges reflect what we quote and what our technicians see across Alamo Heights, Stone Oak, Helotes, Converse, and the surrounding areas.
| Job Type | Home Size / Scope | 2026 San Antonio Price Range |
|---|---|---|
| Standard Air Duct Cleaning | Up to 1,500 sq ft, single HVAC system | $300 – $450 |
| Standard Air Duct Cleaning | 1,500 – 2,500 sq ft, single HVAC system | $400 – $600 |
| Large Home Air Duct Cleaning | 2,500 – 4,000 sq ft, one or two systems | $550 – $800 |
| Two-System Home | Dual HVAC units, any square footage | $650 – $950 |
| Dryer Vent Cleaning (standalone) | Single dryer, standard vent run | $75 – $150 |
| Dryer Vent Cleaning (add-on with duct cleaning) | Single dryer | $60 – $120 |
| HVAC Coil Cleaning (add-on) | Evaporator coil access, light to moderate buildup | $150 – $300 |
| Sanitizing Treatment (add-on) | Full duct system fogging | $150 – $250 |
| Filter Replacement (add-on) | Honeywell, Aprilaire, or Guardsman media filter | $40 – $120 depending on filter type |
These are the prices we quote at Cardinal Air Duct San Antonio as of early 2026. They include the full scope: rotary brush agitation with a Rotobrush system, HEPA-rated negative-pressure extraction with a Nikro vacuum, and containment with Abatement Technologies equipment. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room.
What moves the price up or down? Vent count is the biggest variable. A 1,400-square-foot home with 8 supply vents and 2 returns will land at the lower end. A 3,200-square-foot home with 16 vents, 3 returns, and a second system in the attic pushes toward the top of the range. Accessibility matters too – attic-mounted air handlers in Texas heat, tight crawlspaces under older Alamo Heights homes, and long flex-duct runs in 1990s Hill Country builds all add labor time.
One thing that should never move the price: the technician’s mood when they get to your door. We hand you a written price before any work starts, and that price does not change at the door. If the scope genuinely changes mid-job – say, we find mold that requires different treatment – you approve the new number in writing before we proceed. No surprises, no pressure.
What Affects Air Duct Cleaning Pricing in San Antonio
San Antonio has specific conditions that shape duct cleaning costs here more than in other Texas cities. Here’s what actually moves the needle on your quote:
- Home size and vent count. More supply vents and returns equal more time. A typical San Antonio single-story ranch built in the 1970s or 1980s has 8 – 12 vents, while newer two-story builds in Stone Oak or Cibolo often run 14 – 18 vents across two systems.
- Caliche dust and Hill Country pollen. San Antonio sits on limestone and caliche soil, which produces a fine, powdery dust that finds its way into every duct seam. Combined with cedar pollen season (December through February, when mountain cedar spikes to 10,000 – 20,000 grains per cubic meter), ducts here load up faster than in wetter climates. Heavier contamination means more brush passes and more extraction time.
- Attic vs. closet air handlers. Homes with attic-mounted units – common in newer San Antonio suburbs like Alamo Ranch and Westover Hills – require our technicians to work in 130°F+ attic heat in summer. That adds time and care. Closet or garage units are faster to access.
- Age of the ductwork. Pre-1990 homes in older neighborhoods like Monte Vista or Jefferson often have rigid metal ducts with failing tape seals, or worse, old flex duct that’s collapsed internally. If ducts need minor resealing, that’s a separate quote line item, not hidden in the cleaning price.
- Pet load and occupancy. Multiple dogs or cats, especially long-haired breeds, coat the inside of ductwork with dander and hair that binds with dust into a mat on the duct walls. That takes more aggressive rotary brushing to fully remove.
- Recent renovations. If you just had drywall work, flooring replacement, or a kitchen remodel done in your San Antonio home, construction dust settles inside the ducts. Post-renovation cleanings often require a second extraction pass, which affects labor cost.
We’re an independently owned local business operating as part of the Relay Home Co. family, founded 2005. We quote San Antonio prices because we work San Antonio homes every day. Owner Omar Haddad and our team know that a 1960s ranch in Castle Hills has different duct realities than a 2018 build in Schertz, and our pricing reflects that.
What’s Included in Our Air Duct Cleaning
Before comparing prices, make sure you’re comparing scopes. A $199 duct cleaning special in San Antonio almost always means a shop-vac shoved into one return, ten minutes of noise, and a “done” sticker. That’s not air duct cleaning near me in San Antonio, TX. That’s a performance.
Here’s what Cardinal Air Duct San Antonio includes on every commercial duct cleaning and residential job, at every price point:
- Full-system rotary brush agitation. We run a Rotobrush rotary brush system through every supply vent, return, and main trunk line. The brush physically knocks debris off duct walls – because dust that’s been cooking on Texas duct surfaces for five years doesn’t come loose with suction alone.
- HEPA negative-pressure extraction. A Nikro HEPA-rated vacuum creates negative pressure in the duct system while we brush, so every particle we dislodge gets pulled into the containment unit. HEPA filtration captures 99.97% of particles down to 0.3 microns – including that fine caliche dust.
- Containment setup. Abatement Technologies containment equipment seals off the work area and protects your floors, furniture, and the air you’re breathing during the job. No plastic sheeting shortcuts, no dust cloud in your hallway.
- Before-and-after photo documentation. You see what your ducts looked like before and after. Not because we think you doubt us – because you deserve proof. This is part of The Relay Standard: live trackable arrival, photo proof, digital invoice payable by link.
- Filter check and recommendation. We inspect your current filter and tell you exactly what it needs. If you run a Honeywell, Aprilaire, or Guardsman media filter, we’ll tell you the right replacement spec and can install it same day.
Every job is backed by the 365-Day Done Right Promise. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the longest-standing satisfaction window in the trade, and it covers every job, not select ones.
Is Air Duct Cleaning in San Antonio Worth the Cost?
The honest answer: it depends on your home’s condition, but for most San Antonio homes, a professional cleaning every 3 to 5 years pays for itself. Here’s the math we walk customers through:
San Antonio’s climate means your HVAC system runs hard. We regularly see 2,500 to 3,000 cooling hours per year in Bexar County. That’s among the highest cooling loads in the country. All that air cycling through your ducts means everything in the ducts – the dust, the pet dander, the pollen, the construction debris – gets circulated through your living space every time the AC kicks on.
A dirty system also forces your blower to work harder. The U.S. Department of Energy has documented that even light dust buildup on blower blades and coils reduces airflow and efficiency. In a San Antonio summer, a 10% efficiency drop on a system that runs 8 hours a day translates to real money on your CPS Energy bill, month after month.
And if you’ve been in your home more than five years without a cleaning, you’ve almost certainly got buildup. We’ve pulled 15 pounds of debris out of a single 2,000-square-foot San Antonio home. That’s not unusual. That’s average.
Is it worth $350 to $600? When you consider cleaner air for allergy sufferers during mountain cedar season, better HVAC efficiency through a San Antonio August, and removing years of accumulated filth from the air your family breathes – most of our customers say the first cleaning is overdue and the second one is maintenance.
How to Save on Air Duct Cleaning
We’re direct about pricing, so we’ll be direct about savings too. Here’s how to keep your duct cleaning cost down without cutting scope:
- Bundle dryer vent cleaning. If you’re already having your air ducts cleaned, adding dryer vent cleaning costs $60 – $120 instead of the $75 – $150 standalone rate. More importantly, a clogged dryer vent is a fire hazard – the National Fire Protection Association identifies dryer vent lint as a leading cause of home fires. Get it done while we’re already at the house.
- Combine with HVAC coil cleaning. Evaporator coil cleaning runs $150 – $300 as an add-on. Doing it at the same time as duct cleaning saves a second trip charge and improves system efficiency immediately. If your coils haven’t been cleaned in three or more San Antonio summers, they need it.
- Change your filter before we arrive. A clean filter means the system isn’t pulling in new debris during the cleaning. We’ll still check it, but a fresh filter means a cleaner end result. It’s a $15 move that protects a $500 job.
- Schedule during shoulder season. Spring and fall in San Antonio see less HVAC demand, which gives us more scheduling flexibility. The price is the same year-round – we don’t surge – but you’ll have more options for morning and weekend slots.
- Get the written quote first. Call (254) 347-3897 and we’ll give you a free estimate over the phone based on your square footage, vent count, and system setup. No obligation, no follow-up harassment. Just a clear number.
The biggest savings tip we can give you: don’t fall for the $99 duct cleaning ads. In a competitive market like San Antonio, those bait prices exist for one reason – to get a technician in the door who’s incentivized to upsell you into a “premium” package that costs more than our standard price, often for less actual work. Our standard package is the full scope. It always has been.
How We Price: The Cardinal Way

You’ll know their name before they pull up, and you’ll have a live trackable arrival window through The Relay Standard booking experience. They’ll do a quick walkthrough to confirm scope, then hand you a written price before a single duct is touched. That price includes everything: the cleaning, the equipment, the containment, the documentation. If it changes, you approve the change in writing first.
When the job is done, you get before-and-after photos and a digital invoice you can pay from your phone. No paper, no mailing checks, no awkward payment terminal. Tap and done.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in San Antonio in 2026?
Air duct cleaning in San Antonio costs $350 to $600 for a standard single-system home, and $600 to $950 for larger homes or homes with two HVAC systems. Dryer vent cleaning as an add-on runs $60 to $120. Call (254) 347-3897 for a free estimate on your specific home.
Is it cheaper to clean air ducts or replace them?
Cleaning is dramatically cheaper. Full duct cleaning runs $350 to $950, while duct replacement in San Antonio runs $3,000 to $7,000 depending on home size and duct type. Most ductwork doesn’t need replacement – it needs proper cleaning. If your ducts are older than 25 years or have collapsed sections, we’ll tell you honestly and quote the cleaning separately from any necessary repair work. Call (254) 347-3897 and we’ll assess what your system actually needs.
How much does it cost to clean air ducts in a 2,000 sq ft home in San Antonio?
A 2,000-square-foot home in San Antonio typically costs $400 to $550 for a full air duct cleaning, assuming a single HVAC system and standard vent count of 10 to 14 vents. Homes in neighborhoods like Stone Oak or Alamo Ranch with larger vent counts or attic-mounted air handlers may run slightly higher. Call (254) 347-3897 for a written quote before any work starts.
Can you really get air ducts cleaned for $99 in San Antonio?
No. A $99 duct cleaning in San Antonio is a bait-and-switch. At that price, a company cannot afford the equipment, time, or labor to do real duct cleaning – rotary brush agitation, HEPA negative-pressure extraction, and full containment. What that $99 buys is typically a sales visit where the technician “discovers” problems and pressures you into a $500 to $1,200 “upgrade.” Our standard price ($350 to $600) includes the full scope with zero upsells. Call (254) 347-3897 for a straight-up quote.
Does air duct cleaning improve AC efficiency in San Antonio?
Yes. Removing dust and debris buildup from blower components, coils, and duct walls reduces airflow restriction, which lets your system move air with less energy. In a San Antonio climate where AC runs 2,500 to 3,000 hours per year, even a modest efficiency gain shows up on your CPS Energy bill. Typical duct cleaning costs $350 to $600, and the efficiency benefit compounds every summer after the cleaning. Call (254) 347-3897 to schedule.
How often should air ducts be cleaned in San Antonio?
Every 3 to 5 years for most San Antonio homes. Homes with multiple pets, recent renovations, allergy-sensitive occupants, or heavy caliche dust exposure may need cleaning every 2 to 3 years. The EPA and NADCA both recommend cleaning when visible dust accumulates or when conditions warrant, not on a fixed calendar. If you can’t remember the last time your ducts were cleaned, it’s time. Call (254) 347-3897 for an assessment.
