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 San Leon
Air duct cleaning in San Leon typically costs between $350 and $650 for a standard single-family home, and the work is usually done in a single visit. The final price is quoted as one flat figure per system before any work starts, not per vent, so you won’t watch the number climb once the van is parked outside. If you live on the bay side of Bayshore Drive or up toward 9th Street, we’re familiar with how this peninsula’s air behaves, and we build every estimate around what your ducts actually need. Call (737) 727-2314 for a free estimate.
Why Cardinal Air Duct Cleaning Is San Leon’s Preferred Air Duct Cleaning Company
San Leon is not a big suburban grid. It’s a narrow strip of land wedged between Galveston Bay and Dickinson Bayou, and the homes here run older, lower, and wetter than neighborhoods 20 minutes inland. We know that a bayfront house off 5th Street and a ranch-style place near Highway 146 deal with the same Gulf humidity in different ways, and we look at both before quoting anything. Omar Haddad, our owner, keeps every job under one standard: a written price handed to you before a single duct is touched, a live arrival window you can track from your phone, and before-and-after photos of your own duct interiors. No other cleaner serving San Leon puts photo proof of the work in your hand as standard practice.
Our Air Duct Cleaning crews operate on The Relay Standard: background-checked, uniformed technicians running Rotobrush rotary brushes, Nikro HEPA vacuums, and Abatement Technologies containment units. You’ll know the tech’s name before they open the door. The 365-Day Done Right Promise covers every booking without exception: if the work isn’t right within a year, we return and correct it at no charge. That’s the same promise on a small San Leon cottage as it is on a 4,000-square-foot waterfront build.
Air Duct Inspection in San Leon
Air Duct Inspection in San Leon is the step most homeowners skip and most homes need. Because this peninsula keeps attic-mounted air handlers in a near-constant damp cycle, a visual check of registers and return grilles tells you very little about what’s happening deeper in the flex runs. We run a small video scope through your supply and return ducts to look for collapsed flex, microbial growth, debris buildup, and disconnected sections, then we show you the footage. A full video inspection in San Leon runs $95 to $175, and that fee is waived if you book a full cleaning on the same visit.
Video Scope Walkthrough
We push a camera through both the supply and return sides of your system, including the trunk line and the branch runs. You see what we see, on our screen, before anyone suggests cleaning.
Inspection-Only Report
If your ducts are not dirty, we’ll tell you. You’ll get a written summary of what we found, and we won’t invent a reason to clean. That report is yours whether or not you book work.
Residential Air Duct Cleaning in San Leon
Residential Air Duct Cleaning in San Leon is a source-removal job: we loosen the debris inside your ducts and extract it under negative pressure, so it goes into a HEPA-filtered vacuum, not back into your living room. The process runs the full length of both supply and return ducting, plus the air handler, blower motor, and plenum. For a typical one-story San Leon home, the full system cleaning runs $350 to $650 as one flat price per system, written before we begin. No per-vent pricing, no add-on surprise at the door.
Full System Cleaning
Rotobrush agitation tools work through the supply and return ducts while a Nikro HEPA vacuum maintains negative pressure on the system. We finish by cleaning the blower motor, evaporator coil, and the air handler cabinet itself, which is where most bay-humidity odor actually lives.
Before-and-After Photo Proof
We photograph the inside of your own ducts before we start and after we finish. You’ll receive the images with your digital invoice, so you can see exactly what source removal means on your system.
Trusted Brands We Service in San Leon
We clean and maintain systems built around Trane, Carrier, Lennox, Goodman, Rheem, Ruud, and American Standard components, and we stock the common replacement parts San Leon homes use most: flexible duct sections, filter media, access panels, and drain pan tabs. If your system uses Guardsman or Aprilaire filtration, we’ll clean the housing and swap the media during the same visit. Abatement Technologies containment equipment keeps dust contained while we work, which matters in coastal homes where opening an air handler can send years of settled particles through the house.
Common Air Duct Cleaning Problems We See in San Leon Homes
- Collapsed flex duct runs under bayfront homes. The combination of constant humidity, salt air, and aging flex duct means sections sag, kink, and eventually collapse. We pulled a return drop at a home off 5th Street near the San Leon Municipal Park and found the flex duct slick with microbial growth and collapsed, which meant the return side was pulling almost no air from that end of the house.
- Air handlers that never get cleaned. Most San Leon duct cleanings we do are actually air handler cleanings in disguise. If whoever shows up skips the blower motor and evaporator coil, the musty bay smell stays behind no matter how clean the ducts look. We clean both during every full system job.
- Per-vent quote games. A low teaser price that multiplies by the number of vents once the technician counts them. San Leon homes often have long, damp flex runs that look complex and get priced as if they’re twice the work. We quote one flat price per system, and that number does not change at the door.
- No photographic proof of the work. Without before-and-after images of your own ducts, you cannot tell source removal from a quick register wipe. We provide those photos on every residential cleaning in San Leon.
Pricing for Air Duct Cleaning in San Leon, TX
For a standard single-family home in San Leon, a full residential duct cleaning runs $350 to $650 as one flat price per system. Homes with two independent systems, very long flex runs, or significant microbial growth can run higher, but that number is confirmed in writing before we touch anything. An air duct inspection alone runs $95 to $175, and we waive that fee when you book a full cleaning during the same appointment. Commercial duct cleaning for San Leon restaurants, bait shops, and marinas typically runs $600 to $1,400 based on linear feet of duct and equipment access. Call (737) 727-2314 for a free exact quote.

FAQs About Air Duct Cleaning in San Leon
Every 3 to 5 years for most San Leon homes, though bayfront properties with older flex duct may need it every 2 to 3 years. The peninsula’s onshore Gulf humidity accelerates microbial growth and flex-duct deterioration compared to inland areas like League City, so a 4-year-old system near the bay can look like a 10-year-old system inland. If you’re not sure, book an inspection and we’ll show you the video before recommending anything.
One flat price per system, always. The figure is written on the estimate before we begin, and it does not change based on the number of vents, the length of flex runs, or anything the technician finds after opening the first register. Per-vent pricing is how San Leon homeowners get burned, and we don’t do it.
Yes. Before we start, we photograph the inside of your supply and return ducts, the air handler, and the blower motor. After we finish, we photograph the same locations. Those images arrive with your digital invoice, payable by link from your phone. You are not taking anyone’s word for the work.
San Leon sits on a narrow peninsula between Galveston Bay and Dickinson Bayou, so prevailing Gulf humidity keeps attic-mounted air handlers and flex-duct runs in a near-constant damp cycle. Inland communities get hot, dry attics for most of summer; San Leon attics stay humid, and that moisture feeds microbial growth inside ducts and coils. Cleaning the air handler and blower motor is not optional here, which is why our full system cleaning includes both.
We schedule by appointment, not on-demand. Duct cleaning is a thorough job that takes several hours, and pressure to finish fast is how steps get skipped. Call (737) 727-2314 and we’ll put you on the next available San Leon route, usually within a few days. Your exact time will be live and trackable from your phone, so there’s no waiting around on a vague four-hour window.
