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 Castro Valley
Air duct cleaning in Castro Valley costs between $425 and $780 for a typical single-family home, with most jobs completed in four to six hours. That’s the honest range we quote before any work begins, because we put our pricing in writing first. Castro Valley’s older housing stock and bowl-shaped geography create duct problems most homeowners don’t see until we run a camera through the system. If your home was built before 1980, the odds are high that your ductwork has never been properly cleaned or sealed. Call (806) 606-6902 for a free estimate with a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is Castro Valley’s Preferred Air Duct Cleaning Company
Castro Valley homeowners keep calling us back because we document what we find. Every visit includes a camera inspection of the entire duct system, and the homeowner receives before-and-after photos of every duct run, from the plenum (the central box where ducts meet) to the supply registers. That’s a standard deliverable here, not an upsell. We’ve been doing this since 2013, when CleanRun was founded under the Haven Standard, and the practice hasn’t changed: written price first, photographed evidence at the end.
Our technicians work the streets that back up to Chabot Regional Park and the neighborhoods off Crow Canyon Road, Redwood Road, and Lake Chabot Road. They know what a 1960s ranch on a raised foundation looks like underneath: flex duct chewed through by rodents, disconnected sheet-metal runs, and a supply plenum that hasn’t been opened in decades. Tomas Reyes leads our crews, and every tech is background-checked, uniformed, and identified by name before they step onto your property. We serve Castro Valley from our San Francisco Bay Area office, with local crews dispatched directly to the valley.
The reviews from Castro Valley customers tell the story better than we can. Homeowners consistently mention two things: the written price didn’t change, and the photo record showed exactly what was removed. That second point matters. You shouldn’t have to trust that your ducts were cleaned. You should be able to see it.
Our Air Duct Cleaning Services in Castro Valley
Residential Duct Cleaning
Most Castro Valley homes fall into two categories: postwar ranchers from the 1950s and 1960s, and newer hillside builds from the 1980s onward. The older homes typically have original sheet-metal ductwork that’s now 50 to 70 years old. We clean the entire system: supply and return sides, trunk lines, branch runs, registers, and the air handler cabinet. After cleaning, you get a photo record of every run, including the inside of the supply trunk before and after. A typical single-family home in Castro Valley runs $425 to $780 for a full system clean.
Commercial Duct Cleaning
Small offices, retail spaces, and medical suites along Castro Valley Boulevard and Redwood Road have their own duct challenges. Commercial systems see longer run hours and often share air between multiple tenant spaces. We schedule commercial work around business hours and provide documentation that meets lease and maintenance requirements. Commercial pricing in Castro Valley starts around $900 for smaller spaces and scales with square footage and system size.
Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace or air handler to each room. In Castro Valley homes built with raised foundations, supply runs often travel through crawl spaces, where they’re exposed to rodents, moisture, and decades of neglect. We use negative-pressure extraction (sealing the system and pulling air through a HEPA-filtered vacuum) to remove debris without blowing it back into your living space. Supply-side cleaning alone for a mid-sized Castro Valley home runs $250 to $400.
Return Duct Cleaning
Return ducts pull air back to the system to be reheated or cooled. These are the runs that hunt for air wherever they can find it. In Castro Valley, that often means pulling in wildfire smoke particles, oak pollen, and dust from crawl spaces. A return duct with a cracked seam or disconnected joint will draw unfiltered air from wherever it’s exposed. We clean and inspect every return run, and if we find a disconnect, we document it and quote the repair before cleaning proceeds. Return-side cleaning alone typically runs $200 to $350 in Castro Valley.

The equipment matters. We work with systems from Honeywell and Aprilaire, and our cleaning equipment includes Rotobrush and Nikro machines, professional-grade tools you can look up independently before we arrive. For older Castro Valley homes with original equipment, we’re comfortable working on systems that date back to the original build, and we keep common parts stocked for fast turnaround. If your system uses a Guardsman filter housing or you’re running a modern Honeywell whole-home filtration setup, our techs know the equipment and clean around it without damaging the components.
Common Air Duct Cleaning Problems We See in Castro Valley Homes
- Disconnected or crushed duct runs in raised foundations. Homes built in the 1950s through 1970s often have sheet-metal ductwork that was never sealed properly. Over decades, joints separate, runs sag, and some rooms slowly stop receiving air. We find this on almost every older Castro Valley home we inspect.
- Wildfire smoke residue inside supply boxes. From August through November, smoke from East Bay hills fires gets pulled into return-air systems. The result is a dark, oily particulate layer coating the inside of supply plenums. A cleaning that skips the air handler cabinet and blower motor leaves that residue in place to re-contaminate ductwork within weeks.
- Rodent-damaged flex duct near the park buffer. Homes that back up to the Chabot Regional Park open-space buffer see consistent rodent intrusion in crawl spaces. The flexible duct used in some retrofits gets chewed through, and nests end up inside return runs. A cleaning without sealing lets new rodents re-enter immediately.
- Pollen accumulation from the surrounding oak woodland. The bowl-shaped valley traps pollen from Castro Valley’s oak woodland and annual grasslands. Temperature inversions hold that pollen close to ground level, and return-air systems pull it in all year round, not just in spring.
Pricing for Air Duct Cleaning in Castro Valley, CA
Here’s what we charge in Castro Valley, in writing, before we touch a single panel. A full residential system clean for a single-family home runs $425 to $780. That covers the supply and return sides, all duct runs, registers, the plenum, and the air handler cabinet, and it includes the documented photo record. Smaller townhomes and condos run $325 to $500. If your home has never been cleaned and the system dates to the original build, expect the higher end of the range. Supply-only or return-only cleaning runs $200 to $400 depending on the number of runs and access difficulty. Homes on raised foundations with accessible crawl spaces are typically faster to clean than slab-on-grade homes where ductwork runs buried under concrete.

FAQs - Air Duct Cleaning in Castro Valley
Raised foundations create a crawl space beneath the home, and in Castro Valley that crawl space is where ductwork lives. Rodents, moisture, and decades of accumulated debris enter the system through gaps, disconnected joints, and damaged flex runs. Slab-on-grade homes have ductwork embedded in concrete, which limits access points for pests and debris. If your Castro Valley home sits on a raised foundation, expect more contamination and more repairs during a cleaning.
Castro Valley sits in a topographic bowl ringed by the East Bay hills. During wildfire season, temperature inversions trap smoke close to the ground instead of letting it dissipate. Your HVAC return system pulls that smoke into the ductwork, where it settles as a dark, oily residue on the inside of supply boxes and trunk lines. Homes that run their HVAC during August through November fires routinely show heavy particulate deposits we don’t see in coastal or flatter Bay Area communities. Call (806) 606-6902 and we’ll tell you what we’re finding in Castro Valley homes this season.
Homes that back up to the Chabot Regional Park open-space buffer see frequent rodent intrusion. The typical damage is chewed-through flex duct, nests built inside return runs, and droppings throughout the system. We document all of it with the camera before cleaning begins. The fix usually involves replacing damaged flex with rigid, rodent-resistant duct and sealing every joint so new pests can’t get back in. On one hillside street backing up to the park buffer, our tech pulled a crushed 6-inch flex run from a 1960s ranch crawl space. Rodents had chewed through the outer liner and left a nest of grass and droppings inside the return duct. After a HEPA-filtered negative pressure cleaning and source removal, we sealed the disconnected supply trunk with mastic and replaced the flex with the rigid run, restoring airflow to the primary bedroom.
Sealing is not automatically part of every cleaning, but in Castro Valley it’s often necessary. The older sheet-metal ductwork in postwar homes was rarely sealed at the joints. Over 50 to 70 years, those joints separate, and the system leaks conditioned air into the crawl space instead of your living room. We inspect every run and quote sealing work separately in writing, so you know the cost before we start. If your system needs sealing, we’ll show you the camera footage first.
If the cleaning skipped the air handler cabinet and blower motor, the residue left behind re-contaminates the ducts within weeks. During wildfire season in Castro Valley, that residue is a dark, oily layer from smoke particles. Our cleaning includes the air handler and blower, and we photograph the inside of the cabinet before and after. If your ducts were cleaned recently and already feel dirty again, bring us the invoice and we’ll inspect what was missed for free. Call (806) 606-6902.
