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 Alameda
Air duct cleaning in Alameda is a different job than it is across the estuary in Oakland. The island sits inside a persistent marine layer, and that salt-laden, damp air works its way into retrofit duct systems in ways that inland homes never experience. A typical whole-home cleaning here runs $450-$850, depending on the number of returns and the condition of the flex duct in the crawlspace. We’ve been documenting exactly what we find inside Alameda ductwork since 2013, and the photos tell the real story. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Alameda’s Preferred Air Duct Cleaning Company
Alameda homeowners tend to ask for evidence before they’ll let a crew into their crawlspace. That’s exactly how we’ve worked since our first job in 2013. Every duct run is photographed before and after, and the photo record is yours to keep as part of the standard job file. No manager approval needed, no vague reassurance. Your before photo shows the mildew and crushed flex duct. Your after photo shows the same run clean and sealed.
Tomas Reyes built CleanRun around a simple operating rule: write the price before the panel comes off, and document everything the camera sees. Haven Standard Clause 1 requires a written price before any work begins, on every job, in Alameda and everywhere else we work. That’s the whole point. Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3.
We answer the phone with a live person, not a menu. Scheduling is coordinated from our San Francisco Bay Area office, and crews serve Alameda locally. When you call, you’ll speak with someone who knows the difference between a Gold Coast Victorian and a Bay Farm Island contemporary, because that difference determines how the ductwork was installed.
Our Air Duct Cleaning Services in Alameda
Residential Duct Cleaning
Most Alameda homes we clean were built before central HVAC existed. The ductwork was retrofitted decades later, often through uninsulated crawlspaces under 1900s-era floor framing. That’s where moisture collects. We run negative-pressure extraction through every supply and return run, then photograph the interior of each duct before we seal the access points.
Commercial Duct Cleaning
Park Street storefronts, Webster Street offices, and the small industrial spaces near the former Naval Air Station all share one trait: aging rooftop units pushing air through duct runs that rarely get inspected. We clean commercial systems after hours or on weekends in Alameda, and we deliver the same written photo record for every run. Facility managers get the documentation their tenants or insurers ask for.
Supply Duct Cleaning
Supply ducts are the ones pushing conditioned air into your rooms. In Alameda’s pre-1930 homes, those supplies often run through crawlspaces where bay moisture wicks up through the soil. We find flex duct sagging, mildew growing on the inner liner, and sometimes entire runs crushed by foundation settling. Cleaning the supply side properly means removing the contamination under negative pressure, not just brushing it loose.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in older Alameda homes they’re the most likely place to find a disconnect or a gap. When a return pulls crawlspace air, you’re breathing whatever lives under the house. We camera-inspect every return before cleaning, because the photo often shows problems a homeowner never suspected. A 1910 Craftsman on the Gold Coast had a return that had completely separated from the plenum. The system was pulling mold-laden crawlspace air into the living room every time the furnace kicked on.

BeforeAfterTrusted Brands We Service in Alameda
Our equipment roster includes Rotobrush and Nikro for mechanical agitation, Abatement Technologies for HEPA-filtered negative air, and Honeywell and Aprilaire components for the filtration and air quality work that often follows a cleaning. We name these brands because you should be able to look up what’s being used on your ducts before you agree to a price. When a system needs a new filter housing or a UV sanitizer, we install Honeywell and Aprilaire parts that Alameda supply houses stock locally.
Common Air Duct Cleaning Problems We See in Alameda Homes
- Crushed flex duct in damp crawlspaces. The island’s water table means ground moisture wicks up through soil under older homes, saturating flex duct insulation until it collapses. Owners think the musty smell is just “the Bay air.” It’s not.
- Disconnected return ducts pulling crawlspace air. In pre-1930 retrofits, the return was often an afterthought. Sections separate over time, and the system starts pulling unfiltered crawlspace air, mold spores included, straight into the living space.
- Mildew colonization on duct liners. Persistent humidity from the marine layer condenses inside uninsulated metal ducts during cold nights. The inner surface becomes a breeding ground for mildew, which then gets distributed through the house every time the blower runs.
- Brush-only cleaning that spreads contamination. A rotating brush without negative pressure knocks mildew-laden dust loose but doesn’t capture it. The fine particles drift into living spaces and resettle. Proper negative-pressure extraction with HEPA filtration captures what the brush dislodges.
Pricing for Air Duct Cleaning in Alameda, CA
A standard whole-home cleaning in Alameda runs $450-$850. That’s one flat price per system, written down before any work starts, under Haven Standard Clause 1. The range reflects what we actually find: a 1,200-square-foot East End bungalow with eight runs and clean duct interiors falls on the lower end. A 2,600-square-foot Victorian in the Gold Coast with three returns, deteriorated flex duct, and mildew in the crawlspace runs higher because the work takes longer and requires sealing, not just cleaning. We won’t quote a teaser price and then inflate it once the van is in your driveway. The number on the written estimate is the number you pay. Call (806) 606-6902 and we’ll put the price in writing before a single panel comes off.

FAQs - Air Duct Cleaning in Alameda
The musty smell comes from moisture condensing inside your ductwork, not from the Bay air itself. Alameda’s island geography puts every home inside a damp marine layer with salt-laden air. When that humid air enters an uninsulated crawlspace where the ductwork runs, condensation forms on the cooler duct surfaces. Over months, that dampness feeds mildew inside the ducts. The system blows air that smells fine outside but picks up the mildew odor as it passes through the contaminated runs. The fix is source removal: clean the ducts under negative pressure, then seal the crawlspace penetrations so the moisture can’t wick back in. Call (806) 606-6902 for an exact quote, estimates are free.
A camera inspection shows what’s actually inside your ducts before any cleaning begins. In older Alameda homes, the ductwork was retrofitted decades after construction, often through crawlspaces that were never designed for it. We routinely find disconnected returns, crushed runs, and mildew that a homeowner would never know existed. In a 1910 Craftsman in the Gold Coast, our tech’s camera inspection found the original return duct had been disconnected from the air handler, and a twenty-foot run of crushed flex duct in the crawlspace was saturated with mildew from ground moisture. We used negative pressure and HEPA filtration to source remove the contamination, then sealed the crawlspace penetrations to stop the wicking that caused it. Photographs go in your job record, so you can see the difference between real work and vacuum noise.
Yes. Supply ducts in a Victorian push air out, so contamination on their inner walls gets distributed to every room. Return ducts pull air back, and in pre-1930 retrofits they’re usually the ones with gaps, disconnects, or sections that have separated over time. A Victorian’s return might be pulling crawlspace air through a seam that opened decades ago. We clean supply and return runs separately, camera-inspect both, and document each one. The photo record shows the condition of every run individually, which matters when the real problem is one return pulling air from under the house.
Rust on the exterior of ductwork usually means moisture has been condensing on the metal for a long time. In Alameda crawlspaces, bay moisture wicks up through the soil and keeps the air under the house damp year-round. The rust itself isn’t the immediate health problem. The issue is what’s growing on the inside where the moisture has become condensation. If you see rust, the ducts need a camera inspection before cleaning. We’ll determine whether the metal is still sound or whether sections need replacement. Either way, the underlying moisture source has to be addressed, or the problem returns within a season. Call (806) 606-6902 and we’ll put the inspection on the schedule.
Often yes, though it’s the house that matters more than the neighborhood. The West End has a higher concentration of older Victorians and working-class bungalows with shallow crawlspaces and ground-level access. Those crawlspaces stay damper because they’re closer to the water table. The East End, including the Gold Coast, has larger homes with deeper crawlspaces, but many still run original retrofit ductwork that’s now 50 to 80 years old. The pricing and scope depend on what the camera shows, not on the ZIP code. We’ll work up the written price after the inspection. Call (806) 606-6902 for a free estimate.
