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 Castro Valley
HVAC cleaning in Castro Valley typically costs $325-$610 for a full system, including air handler, blower, and evaporator coil work, with coil-only cleaning running $120-$260. Most jobs are completed in half a day. Our crews know the difference between a Castro Valley hillside ranch with a 60-year-old crawl-space duct run and a newer tract home near Castro Valley Boulevard, because the job looks different in each.
We answer every call at (806) 606-6902 with a live person, and we arrive with a written price before a single panel comes off. That’s the H.A.V.E.N. Standard, and it has been since 2013.
Why CleanRun Air Duct Cleaning Is Castro Valley’s Preferred HVAC Cleaning Company
Homeowners in Castro Valley call us because we show them what’s inside their system before we ask for permission to fix it. Every HVAC Cleaning project we run starts with a camera inspection and ends with a documented photo record of every duct run, before and after. That record is yours to keep, not a marketing prop.
We serve the neighborhoods people actually live in here: street-by-street through the flats near Redwood Road, the hillside subdivisions off Crow Canyon, and the ranch tracts that back up to the Chabot Regional Park open-space buffer. Those park-adjacent properties deserve their own conversation, because we routinely find things there that flat neighborhoods simply don’t produce.
Our founder, Tomas Reyes, built the company on a rule that still governs every job: write the price down first, then do the work. No exceptions. That’s why Castro Valley customers trust us with systems that have been collecting East Bay air for half a century.

Our HVAC Cleaning Services in Castro Valley
The systems we work on here run harder than people realize. Valley inversions hold pollen and smoke low, and older ductwork compounds the problem. These are the services Castro Valley homeowners request most.
Evaporator Coil Cleaning
A Castro Valley evaporator coil in a 1960s-era home off E. 14th Street often carries a packed layer of oak pollen by late spring. That layer insulates the coil, drops heat exchange efficiency, and forces the compressor to run longer. We clean the coil, treat it, and photograph the result. Coil-only cleaning in Castro Valley runs $120-$260 depending on access.
Blower Cleaning
The blower wheel moves air through everything else. When it’s caked with fine particulate from wildfire smoke events, airflow drops and the system strains. In hillside homes with raised foundations, we also check for debris that gets pulled in from disconnected runs. Blower cleaning is included in full-system pricing.
Condenser Cleaning
The outdoor condenser sits in Castro Valley air, which means dust from the hills, pollen, and smoke residue. We clean the coil fins and fan, check refrigerant airflow, and document the condition. This is a $110-$190 service when booked alone.
Air Handler Cleaning
The air handler is where much of Castro Valley’s airborne particulate ends up. We remove the cabinet, clean the fan and coil housing, inspect the filter seat, and seal gaps. In older ranch homes, this is where we often find the first signs of rodent intrusion from crawl spaces.

Common HVAC Cleaning Problems We See in Castro Valley Homes
Here’s what we actually find when a Castro Valley system gets opened up for a cleaning. This is local knowledge, gained job by job since 2013.
- Wildfire smoke film on supply boxes. August through November smoke events leave an oily, dark particulate layer inside supply plenums and trunks. Standard duct cleaning without agitation tools misses it. We use agitation and negative-pressure extraction to remove it. Post-wildfire-season cleaning in Castro Valley is a different job than the same service in Hayward or San Leandro.
- Rodent-damaged flex duct in crawl spaces. Homes that back up to Chabot Regional Park or sit on hillside lots with raised foundations often have chewed or collapsed flex runs below the floor. Air bypasses the filter and pulls crawl-space debris directly into the air handler. We find this constantly in the park-buffer neighborhoods.
- Disconnected or crushed returns on hillside properties. Castro Valley’s slopes mean duct runs sag over decades. Crushed return lines strain the blower and starve the system. A cleaning that doesn’t address the crushed run is half a job.
- Pollen-caked evaporator coils in older systems. The valley’s inversion layer holds oak woodland pollen low for months. On a 50-year-old system with original sheet-metal ductwork, that pollen ends up on the coil. Without coil cleaning and treatment, heat exchange efficiency drops measurably.
Pricing for HVAC Cleaning in Castro Valley, CA
Here are real numbers for Castro Valley’s market. Full HVAC cleaning, including air handler, blower, evaporator coil, and accessible duct runs, runs $325-$610 depending on system size and crawl-space access. Coil-only cleaning is $120-$260. Condenser-only service is $110-$190. If we find crushed flex duct or disconnected runs during the cleaning, that repair is quoted separately in writing before we touch it.
The homes in the hills off Crow Canyon Road and the ranch tracts behind Chabot Regional Park tend to run at the higher end because crawl-space access is tighter and the work takes longer. That’s the honest difference. No per-vent pricing. One flat price per system, written down, before work starts. Call (806) 606-6902 and we’ll put your number in writing.

FAQs - HVAC Cleaning in Castro Valley
Castro Valley sits in a bowl-shaped valley ringed by the East Bay hills and Chabot Regional Park, which causes temperature inversions that trap wildfire smoke close to the ground during August through November. That smoke settles as a dark oily film inside supply boxes and trunk lines, and removing it requires agitation tools plus negative-pressure extraction, not just a vacuum. Flat neighboring cities see less of this. Call (806) 606-6902 for a written quote.
We find rodent-chewed flex duct in crawl spaces, crushed return lines from decades of soil settling, and a layered buildup of oak pollen and wildfire smoke particulate. On a 1960s ranch backing up to the park open-space buffer, our tech pulled the blower motor from a Honeywell air handler and found a rodent-chewed flex duct collapsed in the crawl space, along with a dark oily film inside the supply trunk from repeated smoke events. We replaced the crushed run, performed full source removal with HEPA filtration, and sealed the plenum to NADCA standards. That’s what we mean by local knowledge.
The bowl geography promotes temperature inversions that hold oak woodland pollen and fine particulates low over the valley floor. Return-air systems pull that pollen in continuously, and it concentrates on evaporator coils and blower wheels. Homes in the flats and the hills both deal with it, but hillside systems with older filtration tend to show heavier accumulation. Annual coil cleaning makes a measurable difference here.
A generic duct cleaning without agitation tools leaves the oily smoke film on supply box interiors. A post-wildfire-season cleaning in Castro Valley removes that film, plus smoke particulate embedded in the blower wheel and coil, plus any debris pulled in through damaged crawl-space runs. We photograph the inside of every supply box before and after, so you can see what was removed. That documentation is included with every job.
Sometimes, if the airflow problem is caused by a clogged blower wheel or debris in the air handler. But if the real issue is a crushed flex duct in a crawl space or a disconnected return, cleaning alone won’t fix it. That’s why our written quote identifies duct repairs separately when we find them, and why we photograph everything we find. Call (806) 606-6902 for an exact price in writing.
