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.

Why Cardinal Air Duct Cleaning Is Alamo’s Preferred Air Duct Cleaning Company
Alamo homeowners call us because we treat duct cleaning like the mechanical service it is, not a coupon game. We carry Rotobrush agitation tools and Nikro HEPA-rated vacuums, and every technician is background-checked and arrives in uniform with a name you know before the door opens. We don’t do per-vent pricing, and we don’t add charges once the van is in your driveway. The written price you approve is the price you pay.
We’re part of the Relay Home Co. family, founded in 2005, and held to The Relay Visibility Guarantee on every booking. That means a live trackable arrival window, before-and-after photo documentation of your duct interiors, and a digital invoice you can pay from your phone. Every job is covered 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. Omar Haddad, who leads our Alamo team, is the person you’ll speak with when you call (737) 727-2314.
Our Air Duct Cleaning crew knows Alamo’s housing stock. We understand the long flex runs in 1970s ranch homes off Danville Boulevard, the tight attic access in custom builds near Las Trampas Ridge, and the dust load that comes from living beside open space and oak woodland. That local knowledge means we inspect before we clean, and we clean based on what the camera actually shows.
Commercial Air Duct Cleaning in Alamo
Commercial Air Duct Cleaning in Alamo covers everything from dental and medical offices near the Alamo Plaza shopping center to restaurant kitchens and small retail spaces along Danville Boulevard. These systems run harder than residential ones, often 10 – 14 hours a day, and they collect construction dust, cooking grease vapor, and high volumes of skin cells and textile fibers. We use negative-pressure extraction, meaning the loosened debris goes straight into the HEPA-filtered vacuum, not back into your occupied space. For Alamo commercial properties, expect $900 – $2,500 depending on square footage, duct complexity, and access. A written price is always provided before work starts.
Supply Duct Cleaning for Alamo Businesses
Supply ducts push conditioned air into every room, so buildup here affects air quality across the whole footprint. In Alamo commercial buildings with rooftop units, supply runs often travel through unconditioned plenums where dust bakes onto duct walls. We remove it at the source with rotary brush agitation and HEPA extraction. If a supply run is crushed or disconnected, we document it on camera and repair the issue.
Return Duct Cleaning and Video Inspection
Return ducts pull air back to the unit, and in Alamo’s older commercial suites they frequently leak at joints, pulling attic dust and insulation into the airflow. We seal visible disconnects during cleaning and run a video inspection of both supply and return sides. You see the before-and-after footage, not just a receipt that says the work happened.
Air Duct Cleaning Services in Alamo
Air Duct Cleaning Services in Alamo homes start with a full system inspection, not a blind brush. We camera the supply and return ducts, look for crushed flex runs and disconnected joints, and then clean the entire system under negative pressure with HEPA filtration. A standard single-system home in Alamo runs $450 – $850. Larger custom homes with multiple air handlers or long attic runs can reach $900 – $1,200. The written price covers the entire system, no per-vent counting, no surprises.
Full System Cleaning with HEPA Extraction
We clean the supply ducts, return ducts, air handler, blower motor, and plenum in one pass. Debris is loosened with Rotobrush agitation tools and carried directly into a Nikro HEPA vacuum. Nothing gets blown around and resettled. In Alamo homes with crawlspace ducting, we seal visible gaps and reattach any flex runs that have slipped off their collars.
Dryer Vent Cleaning as Part of the Job
Dryer vents are part of the airflow system in your house, and in Alamo’s older ranch homes they often run 20+ feet through walls and attics. Lint accumulation in those long runs is a leading factor in home dryer fires. We clear the full lint pathway and show you the before-and-after photos. If the vent is crushed or disconnected, we tell you and fix it on the spot.

Trusted Brands We Service in Alamo
We work on systems built around Honeywell, Aprilaire, and Guardsman filtration products, and we stock common replacement filters and components for Alamo homeowners. Our cleaning equipment comes from Rotobrush, Nikro, and Abatement Technologies, which means we use containment units and HEPA-rated vacuums rather than truck-mounted shop-vac shortcuts. If your Alamo system runs Aprilaire media filters or a Honeywell electronic air cleaner, we know how to clean around them properly. You’re getting professional-grade equipment matched to the specific system in your home.
Common Air Duct Cleaning Problems We See in Alamo Homes
- Long flex runs through hot attics: Alamo’s larger lots mean longer duct runs than the compact subdivisions in Walnut Creek or Danville. Those runs sag, get crushed, and accumulate more debris per foot. We see disconnected joints and collapsed sections regularly on camera inspections.
- Crushed returns above air handlers: In 1960s and 1970s ranch homes off Stone Valley Road and Livorna Road, the return plenum is often pinched by strapping or collapsed from heat. That starves the system and pulls attic dust through gaps. We identify and correct it during cleaning.
- Dust resettling after a cheap clean: If a crew blows dust loose without negative pressure, it resettles through supply and return ducts within weeks. We recently cleaned a 1970s ranch off Stone Valley Road where the homeowner complained of dust within a day of a prior cleaning. Camera inspection revealed a crushed flex run and a disconnected joint near the master bedroom. We performed full source removal, sealed the disconnect, and showed the homeowner photos of their own duct interiors.
- Long dryer vent runs packed with lint: Many Alamo homes have laundry rooms on interior walls, pushing dryer vent runs 20+ feet through walls and ceilings. That lint packs up fast and becomes a fire risk. We clear the full run and verify with before-and-after photos.

FAQs About Air Duct Cleaning in Alamo
Most Alamo homes need air duct cleaning every 3 – 5 years. Homes with pets, recent remodeling, or long crawlspace duct runs may need it every 2 – 3 years. If you just moved into an older ranch home in Alamo and don’t know the duct history, get a camera inspection first. It tells you whether cleaning is actually needed or if the system is in decent shape. Call (737) 727-2314 and we’ll help you decide.
We charge one flat price per system, never per vent. Per-vent pricing is how bait-and-switch duct cleaners inflate a $99 coupon into a $900 invoice once they start counting registers in a long-ranch Alamo layout. You get a written price for the entire system before any work begins. That price does not change at the door.
Yes. Every Alamo job includes before-and-after photographs of your own duct interiors, taken with our inspection camera. You see the supply and return ducts, the plenum, and the air handler before we start and after we finish. It’s part of The Relay Standard on every booking, and it’s the only honest way to verify source removal actually happened.
It means the debris is loosened mechanically and extracted under vacuum simultaneously, so it goes straight into a HEPA-filtered collection unit instead of back into your living room. We use Rotobrush agitation tools inside the ducts while the Nikro HEPA vacuum pulls continuous negative pressure on the system. Dust never resettles through the supply and return ducts. That’s the difference between real cleaning and blowing dust around.
No, and that’s deliberate. Proper air duct cleaning in Alamo is a scheduled job that takes 4 – 6 hours with camera inspection, source removal, and before-and-after documentation. We book ahead so you get a live trackable arrival window and a technician with the right equipment. No four-hour arrival windows, no rushed job. Call (737) 727-2314 to schedule a time that works for you.
