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.

AfterAir Duct Cleaning Company in Alamo, CA
Air duct cleaning in Alamo, CA typically runs $449 – $989 for a full system, with most homes in the 2,500 – 3,500 square foot range landing around $600 – $750. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we handle everything from register to return. Alamo’s oak-lined lots, older custom builds, and heavy seasonal pollen mean ducts here fill faster than the county average. Call (737) 727-2314 and you’ll get a live person, a written price before any work starts, and a technician whose name you know before the door opens.
Why Alamo Homes Are Different
Alamo sits in the shadow of the Las Trampas foothills, and that geography shapes what ends up inside your ducts. Homes along Danville Boulevard and the tree-canopied streets off Stone Valley Road collect a particular mix: live oak pollen in spring, fine dust from the hills during dry summer months, and construction debris in the newer estates around Roundhill and Bryan Ranch. Many Alamo homes run their HVAC harder during July and August heat spells, which pulls more particulate through the ductwork.
The housing stock matters too. A 1960s rancher on a half-acre off Livorna Road has different duct realities than a 2010s Mediterranean-style build near the Alamo Country Club. Older systems often have unsealed joints and original flex duct that’s losing its inner liner. Newer homes have tighter envelopes but longer runs, which means more surface area where dust settles. We adjust our approach based on what we actually find, not what a brochure says. That’s why before-and-after photos are part of every job.
Our Main Alamo Services
Most Alamo homeowners call us for one of three things: clearing dryer vents that are backing up, deep-cleaning ductwork that hasn’t been touched in years, or addressing HVAC components coated with the fine particulate this valley produces. Each service has its own Alamo page with pricing and specifics.
Dryer Vent Cleaning in Alamo
Alamo’s larger lots mean longer dryer vent runs. A laundry room on an exterior wall of a Danville Boulevard rancher may vent through ten feet of pipe, but a second-floor laundry in a Roundhill home can push twenty-five feet or more. That added distance traps more lint, especially with the area’s dry, static-prone air. We use rotary brush systems and HEPA extraction to clear the full run, then verify airflow at the termination point. A clogged vent in Alamo is a fire risk, not just a slow-dry annoyance. Dryer Vent Cleaning in Alamo details our process and turnaround.
Air Duct Cleaning in Alamo
A full duct cleaning in Alamo means removing the years of dust, pet dander, and pollen that settle inside registers, boots, and main trunk lines. Homes near Las Trampas Ridge deal with heavier particulate than those closer to downtown. We use Rotobrush agitation tools paired with Nikro HEPA negative-pressure extraction, which means loosened debris gets pulled straight into the vacuum rather than recirculated through your living space. Air Duct Cleaning in Alamo covers pricing by home size and what the walkthrough includes.
HVAC Cleaning in Alamo
The evaporator coils, blower wheel, and drain pan do the heavy lifting in Alamo’s summer cooling season. When those components carry a coating of dust and pollen, your system short-cycles, runs longer, and pushes less conditioned air. We clean coils, blowers, and accessible plenum surfaces using the same professional-grade approach as the duct cleaning itself. The result is a system that actually moves air again. HVAC Cleaning in Alamo explains what gets cleaned and what it costs.
