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 Alamo
Air duct cleaning in Alamo typically costs $450 – $1,100 for a single-system home, and $900 – $2,400 for the large multi-zone estates that dominate this community. The price depends on how many air handlers the house has, how long the duct runs are, and how much debris has accumulated over the years. At Linden Air Duct Cleaning, we put the price in writing before any work starts, so you know the exact cost before our crew even arrives. If you have questions about your system, call (980) 447-2498 and a real person answers, day or night.
Most Alamo homes were built between the mid-1970s and late 1990s, which means most ductwork is now 30 – 50 years old. That’s a long time for flex duct to sit in attics that hit 130 – 140°F every summer. We work these systems every week, and we know what to expect before we open the attic hatch.
Why Linden Air Duct Cleaning Is Alamo’s Preferred Air Duct Cleaning Company
Alamo homeowners have a specific concern when they call us: they want proof. The work happens in attics, crawlspaces, and inside walls. You can’t watch it happen. So we document everything. Every job includes before-and-after photos of your actual ducts, plus a static pressure reading where it matters. You see what we saw. That’s how trust works when the work is invisible.
Every technician who comes to your door in Alamo is background-checked, identity-verified, and arrives in a clean, marked uniform. Before the visit, we send you the tech’s name and photo. At the door, they show a photo ID badge. This is the Threshold Standard, and it’s been our practice since 2004. Marcus Veale leads our team, and he holds every crew member to that standard.
We answer the phone with a live person 24/7. No voicemail loops, no automated menus. When you call (980) 447-2498, a real human picks up. That matters when you’re scheduling around kids, work, or an aging parent at home.
Ductwork Cleaning in Alamo
Ductwork Cleaning in Alamo is rarely a simple one-system job. The custom and semi-custom estates here, most built in the San Ramon Valley development boom of the 1970s through 1990s, often run three or more separate air handlers. That means three separate duct systems, each with its own supply and return runs threaded through unconditioned attic and crawlspace. We clean each system individually using negative-pressure extraction, which means we pull air backward through the ducts under vacuum while agitating the interior walls so debris releases and gets captured at the source. You can’t shortcut this on a 5,000-square-foot home with 40-year-old flex duct.
For a single-system Alamo home, expect $450 – $850. For a typical three-system estate, the range is $900 – $2,400 depending on how many zones and how much debris has built up. The written price covers the whole job, per system, before we start.
Per-System, Multi-Zone Cleaning
We scope every Alamo job by counting air handlers and mapping zones first. A flat “whole house” price on a three-system home under-serves two of those systems. We don’t quote that way. Each system gets its own set of before-and-after photos.
Cameras Before and After
Long attic and crawlspace runs hide problems you can’t see from the register. We run a camera through every trunk line before we start and again after we finish. If a duct has collapsed or kinked from decades of heat, the camera shows it, and we document it so you can decide how to handle it.
Air Duct Inspection in Alamo
Air Duct Inspection in Alamo is often the first thing we recommend for older estates where nobody has looked inside the ductwork in 20 or 30 years. A camera inspection of a typical Alamo home runs $150 – $350, depending on system count and access points. If you book a cleaning, we include the inspection as part of the job at no extra charge.
Here’s why inspection matters here specifically. Original flex duct installed in the 1980s and 1990s has been baking in 130 – 140°F attic heat every summer since it went in. The inner liner can separate, the outer jacket can tear, and the duct can collapse on itself. None of that is visible from your hallway register. A camera inspection finds it before you pay for a cleaning that won’t fix the real problem.
What We Document
We photograph every system before cleaning, after cleaning, and any damage we find along the way. For collapsed or kinked duct, we note the location, take a photo, and give you a written recommendation. You get a zone map showing which systems were cleaned and which need repair.
Static Pressure Checks
When airflow seems weak, we measure static pressure across the system. High static pressure on a multi-zone Alamo estate usually points to one thing: a restricted duct run. We show you the reading and what it means, in plain English.
Trusted Brands We Service in Alamo
We service and clean systems built around equipment from Rotobrush and Nikro, and we work with air-quality products from Honeywell, Aprilaire, and Abatement Technologies. For Alamo customers, we keep commonly needed replacement parts and filtration products available locally through our San Francisco Bay Area dispatch office, which means less waiting when your system needs a filter upgrade or a repair part swapped in. You never get a knockoff filter or an off-brand replacement. We use what the manufacturer specifies for your system.
Common Air Duct Cleaning Problems We See in Alamo Homes
- Collapsed flex duct in attic runs. Decades of 130 – 140°F attic heat causes the inner liner of 1980s and 1990s flex duct to separate and collapse. We find this on a significant number of Alamo estate jobs, and cleaning alone won’t restore airflow when it happens.
- Fine ash and smoke particulate from Diablo wind events. Fall easterlies drive wildfire smoke and fine dust from East Bay hills directly into HVAC intakes. One bad wind season can coat supply trunks with a visible layer of ash that recirculates every time the system cycles.
- Underserviced multi-zone systems. Homes with three air handlers often have two that have never been properly cleaned. A company that quotes one flat price and does a surface pass on registers leaves the attic and crawlspace systems untouched.
- Long duct runs through unconditioned spaces. Alamo’s large lots mean long runs from mechanical closets to far bedrooms. Those runs trap more debris per linear foot than the shorter runs common in denser Walnut Creek or Danville homes.
Pricing for Air Duct Cleaning in Alamo, CA
A single-system Alamo home runs $450 – $850. A two-system home runs $700 – $1,400. The large three-system estates that show up on Stone Valley Road, Roundhill Road, and Livorna Heights typically run $900 – $2,400. What moves the number is system count, duct accessibility, and the depth of debris. Video inspection is $150 – $350 when booked alone, and included when you book a cleaning. Every quote is written, per system, and agreed before work begins. Call (980) 447-2498 and we’ll walk through your home’s specifics and give you a firm number.

FAQs About Air Duct Cleaning in Alamo
Because each air handler runs its own separate duct system, and on a large Alamo estate there are usually two or three of them to clean. A flat “whole house” price almost always means the crew skips one or two systems. Per-system pricing tells you exactly which systems are covered. Call (980) 447-2498 and we’ll count air handlers with you over the phone and give you an honest range.
You should receive before-and-after photos of the inside of your ducts for every system, a zone map showing what was cleaned, and a written service record. We include all of that on every Alamo job, plus static pressure readings where airflow was a concern. If a crew won’t show you photos, you can’t verify the work happened.
Every 3 – 5 years under normal conditions, but homes in the Diablo Valley heat pocket with fall Diablo wind smoke exposure may need it every 2 – 3 years. High summer runtime means more air moving through the ducts, and more debris deposited. If you’re seeing dust on furniture within days of cleaning, or your system smells musty when it cycles, it’s time.
Negative pressure means we connect a vacuum system to your ductwork that pulls air backward through the runs while we agitate the interior walls, so debris releases and gets captured at the source instead of blown around. Source removal means the debris leaves your house entirely. Surface passes that only wipe registers don’t do either, which is why they’re cheap and why they don’t hold up on Alamo’s long runs.
You’ll notice weak airflow from certain rooms, rooms that never reach the thermostat setpoint, or a system that runs constantly without satisfying the call. A camera inspection through the trunk lines confirms it in minutes. We recently worked a 4,800 sq ft custom on Stone Valley Road where the west-zone return trunk had collapsed entirely, killing airflow to four bedrooms. The camera showed it in seconds, and we replaced the crushed section before cleaning. Call (980) 447-2498 if any rooms in your house consistently feel warmer than others.
