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.

AfterFast, Reliable Air Duct Cleaning Across Seguin
Air duct cleaning in Seguin usually runs between $450 and $900 for a complete system on a typical single-family home, and the job takes roughly three to five hours. That’s the honest range, and it’s the number you should have in your head before you start calling around. At Cardinal Air Duct Cleaning, we give you a written price per system before any work begins, so the number we quote is the number you pay. If you’re in Seguin and want a straight answer on cost, timing, or whether your ducts even need cleaning, call us at (737) 727-2314.
Why Cardinal Air Duct Cleaning Is Seguin’s Preferred Air Duct Cleaning Company
Seguin homeowners deal with a specific set of duct problems, and we see them every week. Our Air Duct Cleaning team works in homes from the pre-1950 bungalows near downtown to the new-build subdivisions off Highway 123, and the difference between those two housing stocks changes how we approach every job. Older homes here often have galvanized metal trunks wrapped in insulation that is long past its useful life, while newer homes run flex duct that requires a gentler touch. Knowing which system you have before we quote means the price we hand you is based on your actual ductwork, not a guess.
Local reputation in Seguin matters because word travels fast in a city this size. We work on homes near Texas Lutheran University, through the neighborhoods around Huber Road, and out toward the Mill Creek and Geronimo areas. Customers in Seguin consistently tell us the same thing: they liked knowing the technician’s name before they opened the door, and they liked seeing their ducts on camera before and after. Every technician is background-checked and uniformed, and every job includes before-and-after photo documentation, so you see exactly what we saw inside your system.
We also answer our phones with a live person around the clock. No voicemail loops, no “we’ll get back to you tomorrow.” When you call (737) 727-2314, you talk to someone who can schedule service in Seguin, answer questions about pricing, and tell you what to expect.
Air Duct Cleaning Services in Seguin
Air Duct Cleaning Services in Seguin involve removing the accumulated dust, debris, and biological growth from your supply and return duct runs, your air handler, and your registers. The process uses HEPA-filtered negative-pressure extraction, meaning the loosened debris goes straight into a sealed vacuum, never back into your living room. In Seguin, where summer heat forces your AC to run for months at a stretch, the volume of fine dust moving through residential systems is higher than in cooler markets, and it settles in the ductwork faster.
For a typical Seguin home, a complete air duct cleaning runs between $450 and $900 depending on home size, system configuration, and whether the air handler and blower motor need deep cleaning. We quote one flat price per system and agree on it before we touch a single duct. No per-vent pricing, no add-ons discovered halfway through the job.
Residential Duct Cleaning
Most Seguin homes benefit from a full residential cleaning every three to five years, though homes with pets, recent renovations, or occupants with allergies may need it sooner. We clean supply ducts, return ducts, registers, and the air handler itself so the system moves air efficiently again.
Video Inspection
Before we clean, we run a camera through the ductwork so you and our technician see the same thing. After we finish, we run it again. You receive those images as part of your job documentation. No mystery, no wondering if anything actually changed.

HVAC Duct Cleaning in Seguin
HVAC Duct Cleaning in Seguin goes a step beyond the ducts themselves and includes the furnace or air handler, the evaporator coil, and the blower motor. In this part of Texas, the air handler is often the filthiest component in the entire system, because it runs constantly during the long cooling season and catches everything the filter misses. Leaving it untouched while cleaning the ducts means the system re-contaminates itself within weeks.
Our HVAC cleaning in Seguin starts with a visual inspection of the air handler and coil, followed by containment setup to protect your home during the work. We use professional-grade equipment from Rotobrush and Nikro, not a truck-mounted shop-vac with a brush taped to the end. The process includes cleaning the blower motor, the coil, and the accessible portions of the plenum so the air moving through your freshly cleaned ducts starts out clean at the source.
Pricing for HVAC duct cleaning in Seguin runs about $550 to $1,100 for a complete system including the air handler, depending on accessibility and how much buildup is present. We hand you a written price before any work starts, and that number does not change at the door.
Supply Duct Cleaning
Supply ducts carry conditioned air from your HVAC unit to each room. In Seguin homes, these are often the dirtiest runs because they handle the highest volume of airflow and collect dust at every bend and joint.
Return Duct Cleaning
Return ducts pull air back to the system, and in older Seguin houses they are frequently leaky galvanized trunks that draw in attic air, insulation fibers, and dust from the wall cavities. Cleaning them properly means sealing accessible joints afterward, not just brushing them out.
Trusted Brands We Service in Seguin
We service and clean ductwork connected to all major HVAC brands found in Seguin homes, including Trane, Carrier, Lennox, Rheem, Goodman, and American Standard. Because we see so many systems across the Seguin area, we know the common configuration quirks of each brand and how they affect cleaning access. We carry professional-grade equipment from Rotobrush for rotary brush agitation, Nikro for HEPA vacuum extraction, and Abatement Technologies for containment, which keeps dust from migrating into your living space during the job. If you need filtration upgrades, we stock Guardsman and Aprilaire products and can recommend the right fit for your system. We keep common parts and supplies ready so we can complete most Seguin jobs in a single visit without running back and forth across town.
Common Air Duct Cleaning Problems We See in Seguin Homes
- Flex duct in new subdivisions off Highway 123 that was never properly sealed. Builders often leave gaps at the register collars, which pulls attic air and blown insulation directly into the duct runs. We see this constantly in homes built within the last decade.
- Galvanized metal trunks in older homes near downtown Seguin with failing insulation wrap. The wrap deteriorates, fibers enter the airstream, and dust cakes against the metal. Cleaning these requires a full containment setup so the old insulation doesn’t spread through the house.
- Air handlers and blower motors caked with lint and dust. In Seguin’s humid climate, that buildup mixes with condensation and becomes a paste that reduces airflow and strains the motor. We clean the blower assembly as part of every full system service.
- Dryer vents packed with lint running long distances through walls or attics. Many Seguin homes have dryer vent runs that exceed the code-recommended length, and the lint builds up faster than homeowners expect. This is a fire risk that needs professional cleaning every one to three years.

FAQs About Air Duct Cleaning in Seguin
We charge one flat price per system, not per vent. Per-vent pricing is a bait-and-switch tactic that lets a company quote a low number over the phone and then inflate the bill once the technician counts your registers in person. Our written price covers the entire system and is given to you before any work starts. Call (737) 727-2314 and we will quote your system honestly.
Most Seguin homes need professional duct cleaning every three to five years. You might need it sooner if you have pets, recently renovated, live in an older home with leaky galvanized ducts, or have family members with allergies or asthma. If your registers show visible dust buildup or you smell a musty odor when the AC kicks on, that’s a sign to schedule an inspection. We will tell you honestly if your ducts do not need cleaning yet.
Yes. Before we clean, we run a camera through your ductwork and show you what is inside. After we finish, we run the camera again. You receive both sets of images as part of your job documentation, so you can see exactly what we removed from your system. This is standard on every job we do in Seguin, no exception.
Negative pressure means the cleaning system pulls air out of your ducts through a HEPA-filtered vacuum while we agitate the dust with rotary brushes. Without it, brushing your ducts just pushes dust back into your living space, especially in older Seguin homes with leaky galvanized trunks. Negative-pressure extraction captures the debris at the source and keeps it out of your air.
Your dryer vent is a separate system from your air ducts, and it needs its own cleaning. In Seguin, where dryer vent runs are often longer than code recommends, lint builds up quickly and becomes a fire risk. We recommend having your dryer vent cleaned every one to three years depending on use. We offer dryer vent cleaning as a standalone service or as part of a full home package. Call (737) 727-2314 to add it to your duct cleaning.
