Air Duct Cleaning Company in Castro Valley, CA
Air Duct Repair in Castro Valley usually means one thing: a home built between the 1950s and 1970s whose original galvanized or early flexible ductwork has finally reached the end of its useful life. The canyon and hillside lots here push seasonal wildfire smoke and windborne dust directly into return-air plenums, and older duct runs over crawlspaces disconnect, crush, or fill with debris faster than homeowners expect. We run Rotobrush and Nikro systems for cleaning, but we also repair what others just clean around. Call (833) 589-9902. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Castro Valley Homes Are Different
Castro Valley sits in a warm inland valley where hot, dry summers and seasonal Diablo winds carry wildfire smoke and fine ash from the East Bay hills straight into residential HVAC systems. Many homes here are 1950s to 1970s single-story ranch and split-level builds over raised foundations or slabs, and a large share still runs original rigid galvanized ductwork or early flexible duct. That combination matters. After a red-flag fire-weather event, technicians routinely find ash and fine soot trapped in the return-air plenum and crawlspace ducts of hillside homes along the canyon edges, even when the living space smells clean. The same homes are also more likely to have disconnected joints and pest intrusion in the crawlspace, because the duct runs are older, longer, and exposed to damp winter air. A home in the flatter, more sheltered parts of Castro Valley may need only standard cleaning. A hillside home near the canyon edges often needs a leak assessment first.

Our Main Castro Valley Services
Most Castro Valley homeowners call us for one of two reasons: they want the ductwork cleaned after a dusty summer or a fire season, or they want a dryer vent cleared before it becomes a hazard. Both are core to what we do every day.
Air Duct Cleaning in Castro Valley
For Castro Valley homes, air duct cleaning usually follows a stretch of Diablo winds or a summer of open windows near the hills. We connect professional-grade Rotobrush and Nikro equipment to the duct system and remove the accumulated dust, ash, and pet dander that settles in return plenums and crawlspace runs. Older ranch homes over raised foundations tend to collect more debris than newer builds, because the ducts are longer and the crawlspace air is dustier. We work with the system as it is, document the before and after, and give you a straight read on whether the ducts need repair instead of just cleaning. Detailed pricing, signs, and process are on our Air Duct Cleaning in Castro Valley page.
Dryer Vent Cleaning in Castro Valley
Dryer vent cleaning in Castro Valley is one of the most direct ways to reduce a residential fire risk, and older homes here often have longer vent runs through walls or crawlspaces that collect lint quickly. We remove the built-up lint from the full run, check the termination point outside, and tell you if the vent itself is crushed, disconnected, or made of the old foil-style material that traps debris. Hillside homes with vents exiting through the roof or a long crawlspace run need this service more often than flatter lots with short, straight exhausts. See what is involved on our Dryer Vent Cleaning in Castro Valley page.
Air Duct Repair in Castro Valley
The most common Castro Valley duct repair call starts as a cleaning quote and ends as a leak-sealing job. Homes built in the 1950s through 1970s often have rigid galvanized ductwork that has pulled apart at the seams, or early flexible duct that has collapsed in the crawlspace. After a windy fire season, those same ducts carry fine soot and ash into the home, which means the repair has to happen before the cleaning will hold. We repair what others just clean around. Air Duct Repair is a standalone service for us, not an upsell, because a disconnected return duct in a Castro Valley crawlspace will keep pulling dust and damp air into the house no matter how many times you clean the registers.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat temperature, visible dust streaks around the registers, or a return plenum that rattles when the blower starts are typical signs of disconnected or crushed ductwork.
What it costs in Castro Valley
Ductwork repair in Castro Valley typically ranges from $250 to $900, depending on how many sections need reconnecting, sealing, or patching.
How we do it
We locate the disconnected or compromised section, reconnect or replace it, seal the joints with the right mastic or tape, and test the static pressure afterward to confirm the leak is closed.
Air Duct Replacement
Signs you need it
Duct sections that are crushed flat, rusted through, pest-damaged, or made of degraded early flexible material usually need replacement rather than patching.
What it costs in Castro Valley
Air duct replacement in Castro Valley typically runs $900 to $2,800, with the higher end reflecting long crawlspace runs and multiple branch lines.
How we do it
We remove the damaged section, measure and install new ducting sized to the system, seal both ends, and rebalance the air flow so the affected rooms get the right volume.
Ductwork Installation
Signs you need it
New additions, a converted garage turned into living space, or a system retrofit where the existing duct layout is undersized all call for fresh ductwork installation.
What it costs in Castro Valley
Ductwork installation in Castro Valley typically ranges $500 to $2,500, based on the number of supply and return runs and the access difficulty of the crawlspace or attic.
How we do it
We design the run layout around the existing furnace or air handler, install the new supply and return ducts, seal each connection, and check the air flow at each register.
HVAC Duct Installation
Signs you need it
A furnace replacement or heat pump install where the existing ducts are the wrong size, or a new build in the hills that needs a full supply and return layout, triggers HVAC duct installation.
What it costs in Castro Valley
HVAC duct installation in Castro Valley typically starts around $2,500 and can reach $4,500 for a full system with several branch lines.
How we do it
We run the complete supply and return network from the air handler, seal every joint, insulate where required, and verify the final air flow with the system running.

Why are duct leaks so common in Castro Valley crawlspaces?
Older ranch homes here sit over raised foundations, and decades of damp winter air plus pests and basic settling pull duct joints apart. A crawlspace that never fully dries out accelerates the breakdown.
Can you repair ducts after a fire season or smoke event?
Yes, and in Castro Valley that timing is common. We recommend a thorough cleaning after a smoky stretch so we can see the actual condition of the seams and connections before any repair starts. Call (833) 589-9902 for an exact quote.

Yes, and that is a large share of what we see in Castro Valley. Older galvanized ductwork cleans well, but we will check the seams and connections while we are in there, because loose joints are the most common reason a cleaning does not hold.

What Castro Valley Customers Say
"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Javier Castillo"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Vivian Nguyen"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
