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.
Air Duct Cleaning Company in Alviso, CA
Alviso’s older cottages and bungalows, many built for cannery workers before 1960, run original galvanized ductwork through damp crawl spaces just a few feet above bay mud. That combination of salt air, frequent fog, and vintage metal means our Air Duct Repair work here looks different than it does inland: technicians routinely cut out rust perforations rather than simply brushing dust. Air Duct Cleaning Palo Alto has served Alviso since 2016 with Rotobrush contact-cleaning systems and Nikro HEPA negative-air machines. If your ducts are original to the house, call (833) 620-7085 for an honest assessment before spending money on a cleaning alone.
Why Alviso Homes Are Different
Alviso sits at the southern tip of San Francisco Bay on reclaimed marshland, and that geography sets every rule for the ductwork here. Cool, humid marine air pushes in off the salt ponds and sloughs most mornings, and it carries chlorides that settle inside unsealed duct joints. Galvanized steel that lasted decades in Sunnyvale will show rust blooms in Alviso within ten to fifteen years. The housing stock compounds the problem: most homes are small one-story cottages on raised foundations, with crawl spaces that stay damp from fall through spring. Ducts run through those crawl spaces, so mold spores and rust particles get pulled into the living space every time the blower cycles. The dominant call we get from 95002 is not “my ducts are dusty.” It’s “my ducts smell musty and there’s rust dust on the register.” A few newer infill homes near the former marina edges have sealed modern systems, but they are the exception, not the rule.

Our Main Alviso Services
Two services account for most of the calls we take from Alviso homeowners, and each one has a dedicated page describing the work in detail.
Air Duct Cleaning in Alviso
In Alviso, duct cleaning is rarely just about dust. The salt-laden air and damp crawl spaces mean we are also removing rust scale, mold growth, and the fine gray silt that blows off the salt ponds. Our Air Duct Cleaning in Alviso page covers exactly how we use Rotobrush brush-contact tools to dislodge compacted debris that a plain vacuum will not move, plus the Nikro HEPA negative-air setup that keeps what we dislodge from settling back into your living room.
Dryer Vent Cleaning in Alviso
Dryer vents in Alviso clog faster than they should, because coastal humidity makes lint cling to the corrugated foil ducts common in older cottages. A packed vent is a fire hazard measured in thousands of house fires every year. Our Dryer Vent Cleaning in Alviso page walks through the fire-risk signs, what a full vent cleaning includes, and why we treat this as a safety service rather than an add-on.
Air Duct Repair in Alviso
Air Duct Repair in Alviso usually means surgery on rust. The original galvanized trunks in these pre-1960 cottages were never designed for half a century of salt air, and the joints and low points now show perforations, loose seams, and collapsed sections. In homes along the slough side, we routinely find duct runs that have dropped into pooled moisture under the house, rusting from the outside in. When you repair that metal before replacing a furnace, you stop the system from pulling damp, particulate-heavy air into the rooms where people sleep. The opposite approach, cleaning damaged ducts without fixing them, just postpones the problem by a season. Air Duct Repair is a core part of what we do, not a referral we hand off.
Ductwork Repair
Signs you need it
Rust dust gathering on registers, a musty smell that worsens when the heat runs, and rooms that never reach the thermostat’s temperature are the three most common signs of failing ductwork in Alviso.
What it costs in Alviso
Ductwork repair in Alviso typically runs $350 – $650 per duct line, depending on how much of the run needs sealing or patching.
How we do it
We locate the leaks and rust with a pressure reading and visual inspection, then patch or seal the damaged sections with mastic and metal-backed tape, never fabric tape, which rips within months.
Air Duct Replacement
Signs you need it
Rust perforations larger than a quarter, collapsed flex runs, or ducts so corroded that sections crumble on contact are signs replacement is cheaper than repeated patching.
What it costs in Alviso
Full air duct replacement in Alviso generally starts around $2,500 and can reach $6,500 on a whole-home basis depending on home size and how much crawl space access is available.
How we do it
We remove the failed runs and install new galvanized steel or reinforced flex, sealed at every joint with mastic and pressure-tested before the system is turned back on.
What Air Duct Repair Costs in Alviso
| Item | Typical range in Alviso |
|---|---|
| Ductwork repair per line | $350 – $650 |
| Air duct replacement (whole home) | $2,500 – $6,500 |
| Duct section replacement (short run) | $450 – $950 |
How do I know if my Alviso ducts need repair or just cleaning?
If you see rust dust, smell mold when the blower runs, or have rooms that stay cold, the ducts are likely damaged, not just dirty. A cleaning will not fix a rusted-out run. Call us and we will tell you which one you actually need.
Does repairing ducts really lower energy bills in Alviso?
Yes. Leaking ducts in an Alviso cottage can push 20 to 30 percent of conditioned air into the crawl space. Repairing and sealing them means your furnace works less, which shows up as lower PG&E bills. We give straight recommendations, not a hard sell.
Brands We Service in Alviso

Older Alviso homes with short crawl spaces or ducts buried in mud push prices toward the top of these ranges, because access takes longer and more of the run has to be replaced outright. When we quote a job, we agree on one flat price per system before any work begins, so the number on the invoice is the number you approved.
