Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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.
Fast, Reliable Air Duct Cleaning Across Sienna
Most occupied homes in Sienna need their air ducts cleaned every 3 to 5 years, and a standard whole-system cleaning for a typical Sienna home runs $450 to $850. That’s the short answer. The longer answer involves dust, pet dander, construction debris from newer builds, and the fact that Sienna’s humidity makes duct interiors a magnet for biological growth. Our Air Duct Cleaning team serves Sienna with professional-grade equipment and a fixed price agreed before we touch a single register. Call (737) 727-2314 for an exact quote based on your square footage and system type.
Why Cardinal Air Duct Cleaning Is Sienna’s Preferred Air Duct Cleaning Company
Sienna homeowners call us for Dryer Vent Cleaning in Sienna and more because we run a straightforward operation. We show up in uniform, carry Rotobrush agitation tools and Nikro HEPA vacuums, and hand over a written price before the work begins. No per-vent math at the door. No surprise add-ons once the tech is inside. That’s the entire promise, and it’s backed by our 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge.
We also know Sienna’s housing stock in a way a generic duct company doesn’t. Homes off Sienna Parkway with two-story floor plans have long flex duct runs through attics that regularly hit 140°F in July. Older sections of Sienna with pier-and-beam foundations carry metal trunk lines under the floor, where dust and pest debris accumulate for decades. These two systems need different tools and different pressure setups. Our techs are trained to assess the foundation type before choosing an agitation method, because running the same brush on brittle 40-year-old metal that you’d run on newer flex duct is how ducts get damaged. Omar Haddad, who leads our team, makes sure every tech follows that standard.
Air Duct Repair in Sienna
Air Duct Repair in Sienna typically costs $180 to $480 depending on the extent of the damage, whether that’s a disconnected joint, a crushed flex run, or a torn section of trunk line. Sienna’s newer neighborhoods, like Sienna Village and Anderson Springs, were built fast during the 2010s, and we regularly find flex duct that was never properly supported in the attic. Sagging flex duct pulls apart at the joints, and the air handler starts sucking in attic air. That means insulation fibers and dust blow through the supply registers, and the system works harder to cool the house.
Disconnected or Sagging Flex Duct
When flex duct sags more than about four inches between supports, the liner kinks and airflow drops. The disconnected joint we find in Sienna attics usually happens right at the plenum or at a wye fitting. We reconnect the duct, seal it with mastic, and re-support the run so it holds. This is a repair, not a cleaning, but we almost always recommend doing both while we’re already in the attic.
Crushed or Torn Trunk Lines
Under pier-and-beam homes in older Sienna sections, metal trunk lines get crushed by plumbing work or torn by rodents. A crushed trunk can cut airflow to an entire wing of the house by half. We repair or replace the damaged section and reinforce surrounding joints. Repair pricing includes the materials, and every repair carries a written guarantee plus a free second visit if the fix fails within the 365-day window.
Ductwork Cleaning in Sienna
Ductwork Cleaning in Sienna – meaning the full source removal of debris from supply and return runs, the plenum, and the air handler – runs $500 to $850 for a typical single-system home. That’s a flat price per system, not per vent. We don’t charge per register because Sienna homes with two-story layouts often have 14 to 20 supply vents, and per-vent pricing turns into a guessing game. You’ll know the full cost before the brush goes in.
Full System Cleaning with Negative Pressure
The process starts by connecting a Nikro HEPA vacuum to the supply or return plenum to put the entire system under negative pressure. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. Only after the vacuum is pulling do we run Rotobrush agitation tools through each run to dislodge caked dust, pet hair, and construction debris.
Post-Cleaning Photo Documentation
Every Cardinal job in Sienna includes before-and-after photos of the duct interior. You’ll see the exact condition of your return and supply runs before we start and after we finish. That’s part of The Relay Standard, and it means you never have to wonder whether the work was actually done. If a technician can’t show you the interior of your ducts, they didn’t clean them.
Common Air Duct Cleaning Problems We See in Sienna Homes
- Construction dust in newer builds. Sienna added thousands of homes between 2010 and 2020, and drywall dust, sawdust, and insulation fibers get pulled into duct runs during construction. Builders rarely clean the system before handover, so that debris sits there until a homeowner notices excessive dust on furniture weeks after moving in.
- Crushed flex duct from attic traffic. Sienna homeowners with attic storage or recently completed HVAC, pest control, or cable work often have flex duct that’s been stepped on or leaned against. Crushed flex cuts airflow and forces the blower to work harder, which raises cooling bills during Sienna’s long summer runs.
- Pest debris in pier-and-beam duct runs. Older Sienna homes on pier-and-beam foundations sit on crawl spaces that rodents can enter. Droppings, nesting material, and chewed insulation inside metal trunk lines are common finds. This requires HEPA containment and full source removal, not a quick shop-vac pass.
- Biological growth from Sienna’s humidity. Sienna’s average relative humidity sits above 70% for much of the year. Dark, humid duct interiors in unconditioned attics allow microbial growth to take hold, especially in returns. This is a health issue and a smell issue, and it’s one reason we recommend inspection every few years even if you don’t see visible dust.

FAQs About Air Duct Cleaning in Sienna
Every 3 to 5 years for most Sienna homes, and sooner if you’ve just completed a renovation, have pets that shed heavily, or notice dust returning to surfaces within days of cleaning. Sienna’s humidity shortens the useful interval because biological growth can develop faster in unconditioned duct runs. Call (737) 727-2314 for an assessment based on your home’s specific conditions.
Flat rate per system, always. We quote a single written price for the whole supply and return setup before any work starts, and it does not change. Per-vent pricing penalizes larger Sienna homes with more registers, and it makes the final bill unpredictable. That’s not how we operate. Call (737) 727-2314 for your flat-rate quote.
Yes, it’s standard on every job. Before we start, we run a camera into your supply and return runs so you can see the condition. After cleaning, we photograph the same runs again. You’ll have photo proof of the work, not just a receipt. It’s part of The Relay Standard.
We connect a Nikro HEPA vacuum to your plenum to create negative pressure, then agitate each duct run with Rotobrush tools to dislodge debris. The loosened material goes into the HEPA unit, not back into your rooms. Afterward, we photograph the interior and walk you through what we found. The full process usually takes 4 to 6 hours for a typical Sienna home.
No, and honestly, you should be wary of anyone who does. Proper source-removal duct cleaning requires a half-day of work and a real vacuum setup. Same-day promises usually mean a rushed job or a bait-priced upsell. We schedule within a few days and show up on time with a live trackable arrival window. Call (737) 727-2314 to book.
