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 League City
Air duct cleaning in League City typically runs $425 – $875 for a full residential system, and the work usually takes 3 – 5 hours from setup to final photo documentation. That’s the honest range for a real cleaning here, not a $99 teaser that turns into per-vent charges once the equipment comes off the truck. Our crews work the neighborhoods between Clear Creek and Clear Lake every week, so we know exactly what League City attics throw at us: blown-in insulation, aged flex duct, and Gulf Coast humidity that turns ordinary dust into something stickier. Call (737) 727-2314 for a written quote before anyone touches a register.
If you want the short version: we charge one flat price per system, agreed before work starts, and you get before-and-after photos of your own ducts. No per-vent math. No surprise add-ons when the tech is already in your attic. That’s the whole pitch, because this industry has spent years training League City homeowners to expect the opposite.
Why Cardinal Air Duct Cleaning Is League City’s Preferred Air Duct Cleaning Company
League City homeowners call us because our pricing model is boring in the best way. You get a written number before a single tool comes through the door, and that number doesn’t change. Omar Haddad built this operation around a simple rule: if someone has to ask “wait, what does that charge mean?” after the work starts, we’ve already failed. Every job includes the 365-Day Done Right Promise. If the cleaning isn’t right within a full year, we return and correct it at no charge. That’s not a warranty on paper; it’s a standing offer we’ve never had to hide from.
Our technicians are background-checked, uniformed, and trained on professional-grade equipment: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. When you book through Relay Home Co., you get The Relay Standard: a live trackable arrival window, before-and-after photo documentation of the work, and a digital invoice you can pay from your phone. A live person answers our calls 24/7. No voicemail loops. You’ll know the technician’s name before they pull into your driveway.
HVAC Duct Cleaning in League City
HVAC Duct Cleaning in League City means removing the buildup from both the supply and return sides of your system, not just wiping register faces. In a typical League City home, we run a Rotobrush whip through each duct run while a Nikro HEPA vacuum pulls negative pressure at the air handler. That negative pressure is the key: it means loosened debris travels straight into the vacuum, not back into your living room. Most standard homes here fall between $425 and $875 for a complete system cleaning, depending on square footage and the number of duct runs.
Supply and Return Duct Work
Supply ducts carry conditioned air into your rooms. Return ducts pull air back to the air handler. Both get dirty in League City, but they get dirty differently. Supply ducts collect fine dust and sometimes construction debris from previous renovations. Return ducts here are often worse, because many sit in humid attics and draw air through gaps around the duct boots. We clean both sides fully and document it with camera footage before and after.
Full System Cleaning With Video Inspection
Every full-system cleaning in League City includes video inspection. We run a camera through your ductwork before we start, so we know if we’re dealing with routine dust or something that needs agitation tools rather than the standard whip. After the cleaning, we run the camera again. You see the same duct runs, before and after, on your own phone. That’s the standard, not an upsell.
Vent Cleaning in League City
Vent Cleaning in League City means cleaning the entire duct network, including every supply register and return grille in the home. We remove each register, clean the visible duct boot, then clean the duct run itself using the Rotobrush and HEPA vacuum system. Most League City homes have between 8 and 16 registers plus two or three returns. You pay one flat price for the whole system, not a price that multiplies per vent.
Register and Grille Cleaning
Register faces collect a gray film of dust, pet hair, and cooking residue. That’s cosmetic, but it matters. We remove and clean every register and grille so the air moving through them isn’t passing over a month-old layer of grime. It’s also a visual proof point: if your registers are caked, your duct walls probably are too.
Return Duct Attention
Returns in League City deserve extra attention because of where they live. Many run through attic spaces where the temperature swings from 100°F in the afternoon to cooler at night, pulling humid air past every small gap in the duct seams. That’s how moisture-fed microbial growth starts. Our camera inspection checks for exactly that, and our cleaning process removes what a surface wipe never touches.
Trusted Brands We Service in League City
We work with the equipment League City homes already have and add the filtration products that make sense for a Gulf Coast climate. Our technicians service systems from every major HVAC manufacturer, and we stock Aprilaire media filters and Guardsman filtration products locally so we can swap a clogged filter or upgrade filtration during your cleaning without a second trip. For the cleaning itself, we run Rotobrush brush systems paired with Nikro HEPA-rated extraction. If your system needs containment, as some commercial jobs around Clear Lake do, we use Abatement Technologies units. No truck-mounted shop-vac shortcuts.
Common Air Duct Cleaning Problems We See in League City Homes
- Construction dust packed into returns. League City has grown fast, and a lot of that growth came with attic renovations. Blown-in insulation and drywall dust settle into return ducts and harden into a caked layer that a standard whip alone won’t break loose.
- Sagging flex duct in humid attics. Older flex duct loses its structure over time, especially in Gulf Coast humidity. When it sags, condensation collects in the low spots, and that’s where microbial growth starts. A proper cleaning with camera inspection catches this before it becomes a mold problem.
- Per-vent pricing bait-and-switch. This one’s not a duct problem, it’s an industry problem, and it happens in League City more than it should. A low quote turns into per-register and per-return charges once the crew is in the attic. Our flat per-system price makes that impossible.
- Return ducts with pet hair and dander buildup. Homes with dogs and cats, especially those with the master bedroom near the return plenum, see heavy accumulation on the return side. Regular cleaning here keeps airflow up and keeps the blower motor from working harder than it should.
Pricing for Air Duct Cleaning in League City, TX
A standard full-system air duct cleaning in League City runs $425 – $875 for a typical 1,500 – 2,800 square foot home. That covers supply ducts, return ducts, every register, the air handler chamber, and video inspection before and after. If your home is larger or has extra duct runs, the price goes up accordingly, but you’ll know the number before we start. What affects cost most is the size of the duct system and the amount of buildup we’re dealing with. What doesn’t affect the final price: how many vents you have. We don’t charge per vent.

FAQs About Air Duct Cleaning in League City
Most League City homes need a full duct cleaning every 3 – 5 years. If you have pets, you’re near the water where humidity is higher, or you’ve done a renovation, lean toward every 2 – 3 years. If no one in the home has allergies, there are no pets, and the system was recently cleaned, you can safely stretch it to 5 years. We’ll tell you honestly if your ducts don’t need cleaning yet. Call (737) 727-2314 and we’ll talk through it.
One flat price for the whole system, always. We quote a single number for the entire job, including every supply duct, return duct, register, grille, and the air handler chamber. There is no per-vent math in any Cardinal quote, and the price you agree to is the price on your invoice. If a League City competitor quotes per vent, ask for the total before anyone enters your attic.
We run a camera through the ductwork first to see what we’re dealing with. Then we connect a Nikro HEPA vacuum to the system and run a Rotobrush whip through each duct run, working section by section. The vacuum pulls negative pressure the whole time, so loosened debris goes straight into the containment unit, not into your home. Finally, we run the camera again so you can see the before and after on your own phone. Most League City attics take 3 – 5 hours for a full system.
It can, especially if your ducts have accumulated dust, pet dander, or the kind of moisture-fed buildup that Gulf Coast humidity encourages. Removing that particulate from the air path means your HVAC system isn’t recirculating it through your living space. For the most allergy-sensitive League City households, we also recommend upgrading to a high-MERV Aprilaire filter during the cleaning. We stock them locally and can install one the same visit.
We don’t promise same-day service, because a proper duct cleaning in League City takes planning and equipment setup. What we do offer is a real booking time through The Relay Standard: a live trackable arrival window, a named technician, and a call from a live person 24/7 to schedule it. Most jobs are scheduled within a few days. Call (737) 727-2314 and we’ll get you on the calendar without the phone tag.
