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.

AfterHow Much Does Air Duct Cleaning Cost in Austin?
Air Duct Cleaning services in Austin typically cost $350 to $750 for a standard single-family home with one HVAC system, depending on the number of vents, how accessible the ductwork is, and how much buildup has collected. Larger Austin homes with two systems and 20-plus vents usually land between $700 and $1,200. Dryer vent cleaning, a separate service we handle on the same visit, runs $125 to $225.
Those numbers are for a real clean, not a shop-vac sweep of the visible registers. A proper job means putting the entire duct system under negative pressure, running a rotary brush through every branch line, and pulling the loosened debris out through a HEPA-rated vacuum so it never ends up on your floors. In Austin’s older neighborhoods – think Rosedale, Travis Heights, and Allandale, where a lot of housing stock dates to the 1940s through the 1970s – we regularly find original sheet-metal trunks with disconnected joints and decades of Central Texas dust packed into the returns. That’s the stuff that changes a price quote.
Cardinal Air Duct Cleaning gives you a written price before any work starts. Not a ballpark over the phone that grows once a technician is inside your attic. That’s part of operating as the air duct specialist within the Relay Home Co. family, and it’s why we put real ranges on this page instead of hiding behind “call for pricing.”

- Written price before work begins, every booking
- 365-Day Done Right Promise covers every job – if it’s not right, we return and correct it at no charge
Air Duct Cleaning Cost Breakdown (2026)
Here’s how a typical Austin air duct cleaning invoice breaks down. Every one of these lines is quoted in writing before a technician touches a register, and the number doesn’t move at the door.
| Service | Typical Austin Range | What It Covers |
|---|---|---|
| Base air duct cleaning (1 system, up to 10 vents) | $350 – $500 | Supply and return lines, registers, main trunk, negative-pressure extraction |
| Additional vents (per vent) | $12 – $25 | Each register or branch line beyond the base count |
| Second HVAC system | $200 – $350 | Full cleaning of a separate system’s ductwork |
| Dryer vent cleaning | $125 – $225 | Full lint removal, exterior vent check, airflow verification |
| HVAC unit / coil cleaning | $150 – $400 | Evaporator coil, blower, and cabinet cleaning |
| Mold or microbial treatment | $300 – $800 | EPA-registered application after cleaning, when growth is present |
| Duct sanitizing / fogging | $150 – $400 | Optional antimicrobial fog for odor or post-remodel jobs |
| Flex duct replacement (per run) | $150 – $350 | Replacing crushed, torn, or rodent-damaged flex runs |
What pushes a quote up? Square footage and vent count are the two biggest levers, since labor scales with how many branch lines a tech has to work. Accessibility matters almost as much – a single-story home in Mueller with attic ductwork laid out cleanly takes far less time than a 1920s bungalow in Hyde Park where the only way into the crawlspace is through a closet floor. Excess buildup adds labor too. We’ve opened returns in East Austin rentals that hadn’t been touched in 15 years, and the extraction time alone doubles. Optional add-ons like mold treatment or sanitizing bump the total, but they’re quoted separately so you can see exactly what you’re paying for and decide.
What pushes it down? A clean, accessible system with a straightforward layout. If your ductwork is newer and the last cleaning was recent, you’ll sit at the low end of every range above.
What Affects Air Duct Cleaning Pricing in Austin
- Number of vents and systems. Most Austin quotes are built per vent on top of a base fee. A 1,800-square-foot home in Crestview with 12 vents prices differently than a 3,400-square-foot two-story in Circle C with 22 vents and two air handlers. Two systems means two full cleanings, and the second is rarely free.
- Duct material and layout. Rigid sheet metal cleans fast and holds up to a rotary brush. Flexible duct – common in Austin homes built after 1995 – is harder to clean thoroughly and easier to damage, so careful work takes longer. Long runs or ductwork buried under insulation add time on both.
- Buildup level and contamination. Standard household dust is one thing. Rodent droppings, nesting material, or visible mold growth changes the job entirely – containment goes up, treatment gets added, and the price reflects it. Austin’s humid spring and fall shoulder seasons keep attics damp enough that we see more microbial growth here than in drier Texas markets.
- Accessibility. Attic and crawlspace access drives labor more than most homeowners expect. If a technician can walk a clean attic in Round Rock, that’s one thing. If they’re belly-crawling a 1940s pier-and-beam in Bouldin Creek with 18 inches of clearance, that’s another.
- Add-on services. Dryer vent cleaning, coil cleaning, and sanitizing get quoted as separate line items. Bundling them on the same visit usually saves the trip charge versus booking them separately.
- Who you hire. A truck-mounted shop-vac operation and a company running Rotobrush rotary brushes and Nikro HEPA vacuums are not the same service, and they don’t cost the same. The cheap quote often means debris pushed back into your living space instead of extracted out of it.
Why Austin Homes Cost What They Cost
Austin’s climate does real work on ductwork. Cedar pollen season runs heavy from December through March, and that fine pollen gets pulled into return air and settles along duct walls. Our summers push systems to run eight or nine months straight, which means more air moving through the same ductwork for more hours per year than a home in a milder climate. The result is faster buildup and more frequent cleaning recommendations.
Then there’s the housing mix. Austin has a wide spread between century-old bungalows and new-build subdivisions, and that spread shows up in pricing. In neighborhoods like Zilker or Clarksville, we often find original ductwork with taped joints that have long since failed – that’s a cleaning plus a repair conversation. In newer construction out in Pflugerville or Leander, the ductwork is usually sound, but builders don’t always seal every joint, so we see leakage that affects both air quality and your energy bill-much like the issues that shape air duct cleaning costs in Brooklyn, NY across its mix of old and new housing stock.
Every job we run includes before-and-after photo documentation. You see what came out of your ducts and what they look like after. That matters when you’re comparing a $350 quote against a $900 quote and trying to figure out why they’re different.
How to Save on Air Duct Cleaning
You don’t need to pay top of range to get a thorough cleaning. A few practical moves keep the number down:
- Book duct cleaning and dryer vent cleaning together. The dryer vent is a separate service, but doing it on the same visit saves a return trip. Most Austin homeowners bundle them and cut $50 to $100 off the combined total.
- Get the vent count before you compare quotes. A $299 quote for “air duct cleaning” that turns out to cover only eight vents isn’t cheaper than a $450 quote covering 16. Ask for a per-vent number so you’re comparing the same job.
- Fix obvious leaks first if you can. If a technician finds disconnected joints or torn flex runs, addressing them before a full cleaning means you’re not paying to clean ductwork that’s about to be replaced anyway.
- Skip sanitizing unless you need it. Antimicrobial fogging is worth it after rodent activity, water damage, or a remodel. If your ducts are just dusty, a thorough mechanical cleaning handles it without the extra line item.
- Ask about the 365-Day Done Right Promise. It’s included on every booking, not an upsell. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it means you’re not paying twice for a job that wasn’t done properly the first time.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Austin?
Most standard Austin air duct cleanings run $350 to $750 for a single-system home, and $700 to $1,200 for homes with two systems or 20-plus vents, which differs from How Much Does Air Duct Cleaning Cost in Boston, MA? (2026 Price Guide). The exact number depends on vent count, duct material, and how much buildup is present. Call (737) 727-2314 for an exact quote – estimates are free and the written price never changes at the door.
Is it cheaper to clean my air ducts or replace them?
Cleaning is almost always cheaper unless the ductwork itself is failing. A full cleaning runs $350 to $750; replacing an entire duct system typically starts around $2,500 and climbs past $6,000 depending on home size and layout. If your ducts are intact but dirty, cleaning wins by a wide margin. If a technician finds crushed flex runs or collapsed trunks, replacing just those sections – usually $150 to $350 per run – is the middle path. We’ll tell you which situation you’re in before any work starts.
How often should Austin homes get their air ducts cleaned?
Every three to five years is the general recommendation, but Austin’s climate and pollen load push many homes toward the three-year mark. If you have pets, allergies, recent remodeling, or you’ve seen dust blowing from your registers, two to three years is more realistic. Homes near heavy cedar pollen areas like the hills west of town often need it closer to every two years. Call (737) 727-2314 and we’ll tell you honestly whether you’re due.
Why do air duct cleaning quotes vary so much in Austin?
Quote differences of $300 or more usually come down to equipment and scope. A company using a truck-mounted shop vac charges less because the job is faster and less thorough. A company running Rotobrush rotary brushes and Nikro HEPA vacuums with Abatement Technologies containment does more work: sealing the system, brushing every branch line, extracting under negative pressure. Those aren’t the same service, and the price reflects it. Ask any company what equipment they use before you compare numbers.
Can you clean my air ducts the same day I call?
Often yes, depending on the day and your neighborhood. We run same-day availability across most of Austin, and our booking system gives you a live, trackable arrival time so you’re not stuck waiting through a four-hour window. A live person answers the phone 24/7 – no voicemail loop. Call (737) 727-2314 to check today’s openings.
Does air duct cleaning actually lower my energy bill in Austin?
It can, but modestly – think 5% to 15% on cooling costs when ducts are heavily clogged or leaking. The bigger win is air quality and system lifespan. When ducts are restricted, your HVAC blower works harder and runs longer, which shortens equipment life. In a city where systems run eight-plus months a year, that wear adds up. Call (737) 727-2314 to schedule an inspection and we’ll tell you what we find.
