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 HVAC Cleaning Across Alameda
HVAC cleaning in Alameda typically costs $425-$730 for a full system on a single-family home, with the work done in one visit by a two-person crew. The island’s salt-heavy air and older housing stock mean ducts here collect a different kind of residue than you’d see in Oakland or San Leandro. We coordinate scheduling from our Bay Area office and crews arrive in Alameda daily. If you’ve noticed a musty smell when the heat kicks on, call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is Alameda’s Preferred HVAC Cleaning Company
Alameda homeowners deal with something most of the East Bay doesn’t: a marine layer that sits over the island nearly year-round. That humidity works its way into crawlspaces under Gold Coast Victorians and Fernside bungalows, and from there into the ductwork. Our techs know what that means in practice. We’ve pulled flex duct from a 1912 Craftsman near the Gold Coast where the outer jacket was dripping and the inner liner showed black mildew along the entire bottom third. That’s not a hypothetical. It’s what bay moisture does to a ground-level crawlspace over a century.
Established in 2013, CleanRun has served 52,000+ homes, every one with a written price before work started. Tomas Reyes leads our team, and every tech who steps onto your property is background-checked and uniformed. We publish our license on the page, not in a footer. For Alameda specifically, we carry equipment sized for tight retrofit mechanical closets and narrow crawlspace access points common in pre-1930 construction. When you call, a live person answers. When we finish, you get a documented photo record of every duct run, inside before and after.
What Alameda Homeowners Say
The pattern in our Alameda reviews is consistent: customers didn’t believe how much was actually inside their ducts until they saw the before photos. One homeowner in the East End told us the camera showed a 3-inch debris build-up at the first elbow of a return duct she’d assumed was fine. That’s the evidence-first standard we’ve held since day one. No vague reassurance. No “your ducts were really dirty.” We show you what we found, what we did, and what it looked like after.
Our HVAC Cleaning Services in Alameda
We offer a full range of HVAC Cleaning services, but three matter most for Alameda’s housing stock: evaporator coil work, air handler cleaning, and coil treatment. Here’s what each involves on the island.
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and does the actual cooling work. In Alameda, it runs in a damp environment for most of the year, which means the coil collects a biofilm of dust and moisture that hardens into an insulating gunk. That film cuts heat transfer and forces your system to run longer. We pull the coil, clean it with professional-grade equipment, and photograph it before and after. A coil in a Central Alameda condo near Park Street that hasn’t been cleaned in five years will look dramatically different.
Air Handler Cleaning
The air handler is the box that holds the blower, the coil, and often the filter. In older Alameda homes, air handlers were retrofitted into hall closets or attic spaces never designed for them. Debris accumulates around the blower wheel, and in damp crawlspace-adjacent installations, mildew forms on the cabinet interior. We clean the blower assembly, the cabinet, and the drain pan, then photograph the result. A clean air handler in a Bay Farm Island home moves air with less resistance, which shows up as better airflow at every register.
Condenser Cleaning
The condenser is the outdoor unit. On Alameda, it gets a double dose of problems: salt-laden air accelerates fin corrosion, and coastal fog keeps the coil damp, which turns pollen and road dust into a crust. We wash the condenser with proper coil cleaner, straighten bent fins, and check refrigerant pressures. A condenser behind a Gold Coast Victorian on Grand Street collects different debris than one in a newer Bayport townhome. We clean both properly.
Blower Cleaning
The blower wheel is what pushes air through your entire system. In Alameda’s older homes, blower wheels often haven’t been touched since installation. Dust builds unevenly on the wheel blades, throwing the wheel out of balance and straining the motor. We remove the blower, clean each blade, and remount it. The difference in noise is usually immediate. A Fernside homeowner can hear it the first time the system kicks on after we leave.

BeforeAfterTrusted Brands We Service in Alameda
We work on systems from every major manufacturer, and we use professional-grade equipment from brands you can look up independently: Rotobrush, Nikro, and Honeywell. When a repair is needed, we keep common parts in our Bay Area stock and can source Alameda-specific components quickly. Whether your system is a Carrier in a 1920s Gold Coast Colonial or a Trane in a newer West End build, our techs know the equipment. We don’t sell parts you don’t need, and every part is documented on the written scope before it goes in.
Common HVAC Cleaning Problems We See in Alameda Homes
- Condensation inside supply and return ducts. Alameda’s persistent marine layer keeps crawlspace humidity above 75% most of the year, and ducts in uninsulated crawlspaces under pre-1930 homes sweat from the outside in. That condensation becomes mildew that recurs after every cleaning unless the duct run is resealed. We find this constantly in West End homes built before the bridge.
- Crushed or disconnected flex duct runs. Retrofit HVAC systems in Alameda’s older homes often use flex duct jammed into crawlspaces and attics as an afterthought. Duct gets stepped on, compressed by stored boxes, or pulled loose at joints. A register-only clean misses this entirely. Our camera inspection finds it, and we show you the footage.
- Corroded original metal ducts. Salt-laden bay air eats at older galvanized ductwork, leaving pinhole leaks that pull damp crawlspace air into the system. This undoes the benefit of even the best filter change. We see this on original duct systems in intact Victorians throughout the Gold Coast and East End. The fix is sealing, not just cleaning.
- Mildew colonies in fiberglass duct lining. Fiberglass duct liner gives mold something to hold onto. When Alameda’s crawlspace humidity stays above 75% for weeks at a time, visible growth appears. A home a mile inland in Oakland with the same duct materials may stay dry enough to avoid it. The island’s geography changes the math.
Pricing for HVAC Cleaning in Alameda, CA
A full HVAC cleaning for a typical Alameda single-family home runs $425-$730, depending on the system size and the number of duct runs. Evaporator coil cleaning alone runs $180-$265. Air handler cleaning runs $190-$285. Coil treatment with an antimicrobial coil coating runs $140-$210 per coil. If duct sealing is needed after cleaning, that adds $85-$160 per accessible run depending on complexity. Older homes with original metal ducts often need more sealing work, and that’s reflected in the written scope you receive before we start. We price per system, not per vent, and we don’t bait with a low coupon price. Every job starts with a written price under Haven Standard Clause 1.

FAQs - HVAC Cleaning in Alameda
The smell isn’t coming from your filter. In Alameda, it’s almost always mildew inside the ducts or on the evaporator coil, fed by the island’s persistent humidity. Changing the filter treats the symptom’s weakest link. Call (806) 606-6902 and we’ll camera-inspect the duct runs to find the growth.
Yes, with the right approach. Original metal ducts from the early 20th century can be cleaned safely, but they need to be inspected for corrosion and pinhole leaks first. We use lower-pressure negative extraction on older systems and document every section with the camera before and after to make sure cleaning doesn’t worsen existing damage.
Cleaning damp ducts without fixing the moisture source is a waste of money. We check the crawlspace humidity and the condition of the duct jacket as part of the inspection. If humidity is over 75%, we’ll recommend sealing or a dehumidifier strategy before or alongside the cleaning, and we’ll put that in writing.
Common, yes. Normal, no. Retrofit flex duct in pre-1930 homes often runs through crawlspaces where it gets compressed or disconnected. A crushed run can cut airflow by 60% or more, and a register-only clean won’t catch it. Our camera inspection finds these problems on a significant share of Alameda jobs.
No. That “Bay smell” is often mildew or salt-laden dust inside the duct system, not a harmless feature of island living. You’ll know the difference after we clean and seal the runs. If the smell persists, we’ll tell you why and what the next step is, with a documented photo record to back it up.
