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.

Air Duct Cleaning Company in San Ramon, CA

Air duct cleaning in San Ramon typically costs $350 – $650 for a full system on a standard single-family home, and most jobs are finished in 3 – 5 hours. San Ramon’s combination of rolling hills, wildfire-season smoke, and a housing stock dominated by homes built from the late 1980s through the early 2000s means duct systems here collect a specific mix of dust, construction debris, and seasonal particulate. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we work throughout San Ramon with one standard: a written price before any work starts.

Why San Ramon Homes Are Different

San Ramon sits in a valley ringed by hills, which creates a temperature inversion pattern that traps dust and pollen close to ground level, especially from June through October. Homes in communities like Dougherty Valley, Windemere, and Gale Ranch were mostly built in the 1990s and 2000s, and many still have their original flex duct runs. Flex duct breaks down over time; we regularly find collapsed inner liners and separated connections behind registers in these neighborhoods. Add in the wind that funnels through from the Altamont and the smoke that drifts in during fire season, and most San Ramon systems carry more fine ash and silt than homeowners expect.

Hillside homes along Bollinger Canyon Road and Norris Canyon Road often have long duct runs in attic spaces that bake in summer heat, which dries out any accumulated debris and makes it harder to extract once it bakes onto duct walls. Many HOA communities in San Ramon also have exterior vent requirements that change where dryer exhausts and attic vents can terminate, so we check compliance as part of every job.

Our Main San Ramon Services

Most San Ramon homeowners call us for two reasons: visible dust buildup around registers and dryers that take two or three cycles to finish a load. We offer three core services, each with its own San Ramon page.

Dryer Vent Cleaning in San Ramon

San Ramon’s two-story homes often have dryer vents that run 15 to 25 feet through walls and floors before they exit, which is exactly the kind of run that clogs quickly and quietly. We use a Rotobrush rotary system to break through the compacted lint that builds up at every bend, then pull it out with a Nikro HEPA vacuum so nothing escapes back into your laundry room. A clogged dryer vent in San Ramon isn’t just slower; it’s a fire risk, and homes with long interior runs are the highest priority. See our Dryer Vent Cleaning in San Ramon page for full pricing and what the job includes.

Air Duct Cleaning in San Ramon

When we clean air ducts in San Ramon, we don’t just vacuum out the registers. We run a rotating brush through every supply and return line to loosen the dust, pet dander, and construction debris that wind and wildfire smoke push into the system, then we extract everything with negative-pressure equipment. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. Homes in Dougherty Valley and Windemere tend to have two zones and more duct footage than older San Ramon homes, which changes the time and cost. Visit Air Duct Cleaning in San Ramon for the full breakdown.

HVAC Cleaning in San Ramon

HVAC cleaning in San Ramon covers the full mechanical path: coils, blower motor, drain pan, and the ductwork that carries conditioned air. The blower and evaporator coil in a San Ramon attic system collect fine dust during the hot months when the AC runs for weeks without stopping, and that buildup cuts airflow and cooling capacity. We open the unit, clean the components with professional-grade tools, and verify the system runs at proper static pressure before we leave. The full scope and pricing are on our HVAC Cleaning in San Ramon page.

Full air duct cleaning, dual HVAC system $550 – $850

What pushes a San Ramon price toward the top of these ranges is duct footage. A 4,000-square-foot home in Gale Ranch with a dual-zone system and long attic runs will naturally cost more than an 1,800-square-foot ranch near San Ramon Valley High School. Whatever the number, you get it in writing before any work starts, and it does not change at the door.
