Air Duct Cleaning Company in San Ramon - One Price Per System, Agreed Before We Start

Air Duct Cleaning Company in San Ramon, CA

San Ramon’s builder-era flex duct is now old enough to fail, and much of our work here is Air Duct Repair rather than a simple cleaning: crushed runs over second-story ceilings, tapes peeling off flex joints inside hot attics, and return plenums that still hold drywall dust from the build. The 1980s-to-2010s tract homes across Dougherty Valley and Bishop Ranch share a common layout, so we know the routes the ductwork takes before we take a panel off. For anything related to duct work in San Ramon, call (877) 212-3243. We answer 24/7, with fast dispatch from 7am to 7pm.

Why San Ramon Homes Are Different

San Ramon is a master-planned city, not a patchwork of eras. Nearly every house here went up between the late 1980s and the 2010s, first through Bishop Ranch and Canyon Creek, then through the phased grading of Dougherty Valley, Windemere and Gale Ranch. That means one dominant duct type: flexible duct routed through conditioned attics and second-floor joist bays, feeding a central air handler.

The inland San Ramon Valley climate loads those systems hard. Summers run in the 90s and 100s, so the cooling runs long and pulls dust and pollen through the whole system every season. Winters are cool and damp, with inversion fog settling over the valley, and that wet-dry swing is what drives condensation and mold inside attic ductwork. The other thing we find here goes back to the land itself: Dougherty Valley was cut through former ranchland and vineyards, graded and built in phases, and plenty of homes still carry construction debris in the return plenums because the system was never properly cleaned after handover.

Our Main San Ramon Services

Most San Ramon homeowners call us about one of two things: cleaning out a system that has been running dirty for years, or clearing a dryer vent that has never been touched. Both have their own pages below.

Air Duct Cleaning in San Ramon

In San Ramon, cleaning means working through long flex runs feeding bonus rooms and second-story bedrooms, plus the return plenums that tend to hold the most debris. We agitate the duct walls with a Rotobrush, then extract with Nikro HEPA equipment while Abatement Technologies negative-air units hold the dust down. In a city where summer runtimes are long, that dust load builds fast, and one pass rarely tells the story. For the full method and what it includes, see Air Duct Cleaning in San Ramon.

Dryer Vent Cleaning in San Ramon

Builder-era tract homes often run dryer vents through longer paths than homeowners expect, sometimes up through a second-story wall before exiting the roof. Lint packs those runs, restricts airflow, and raises the heat load on the dryer itself. This is a fire-safety job, not an upsell, and we treat it that way. Details on how we clear a South San Ramon Valley vent are on our Dryer Vent Cleaning in San Ramon page.

Air Duct Repair in San Ramon

Air Duct Repair in San Ramon is mostly a question of age and material. Flex duct from the late 1980s through the 2000s was never built to last 40 years inside a hot attic, and the long runs into bonus rooms and second-story bays are where it gives out first. Add a valley climate that swings from 100-degree summers to damp, foggy winters, and the joints, tapes and liners take a beating that older East Bay housing stock never sees. Cleaning without repair just pushes air through the same leaks. We repair what we find, and for the deeper scope of that work, see our Air Duct Repair page.

Ductwork Repair

Signs you need it

Look for rooms that never reach the thermostat setting, visible sagging or crushed flex in the attic, tape peeling at joints, or a dust film returning to surfaces within days of cleaning.

What it costs in San Ramon

Ductwork repair typically runs $250-$900 depending on how many joints, runs or transitions need to be re-sealed or re-supported, and the written estimate sets the final price.

How we do it

We isolate the affected run, re-tape and re-seal the joints with mastic and foil tape, re-support sagging flex to restore its full diameter, and verify airflow at the register before we close up.

Air Duct Replacement

Signs you need it

Replacement becomes the right call when the flex liner is torn or contaminated beyond cleaning, the duct has collapsed in the ceiling cavity, or the runs were undersized for the room they serve.

What it costs in San Ramon

Air duct replacement typically falls in the $1,800-$6,500 range for a residential system, based on the number of runs and the routing complexity through conditioned attic space, with the written estimate setting the final price.

How we do it

We map the existing runs, remove the failed flex, install new insulated duct to each register, and seal the connections at plenum and boot so the system holds pressure.

What Air Duct Repair Costs in San Ramon

These are typical ranges for the work we see in San Ramon homes, not a quote. Every job gets a written estimate before any work starts, and that estimate is the price.

Can you repair ducts hidden above a second-story ceiling?

Yes. Most San Ramon two-story homes route flex through joist bays and attic cavities, and we access those runs through existing panels or small, clean cuts we patch afterward. If the run is inaccessible, we reroute it rather than leave it leaking.

Is duct repair worth it on a 1990s San Ramon tract home?

Usually, yes. The air handler and duct layout are often still serviceable, and repairing the failed runs costs far less than a full system change-out. Leaks and crushed flex in those homes are the real cause of uneven cooling, not the equipment.

Brands We Service in San Ramon

We work with Honeywell and Aprilaire controls and filtration, Abatement Technologies containment units, and Guardsman components where they fit the system, and we can recommend and install filtration upgrades as part of a whole-system fix. Turnaround depends on the parts your job needs. See our brands.
