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.
Fast, Reliable Air Duct Cleaning Across San Ramon
Air duct cleaning in San Ramon typically runs $350-$650 for most single-family homes, with whole-system jobs that include the air handler and all supply and return lines taking a full morning to complete. We’re the local team that serves San Ramon from our Bay Area dispatch office, and we know the specific duct problems this city’s housing stock creates. Call (469) 972-3151 for a free written estimate before any work begins.
San Ramon sits in an inland valley where summer temperatures push 95-105°F for months, forcing HVAC systems into heavy continuous use. That constant airflow pulls fine dust from the dry annual-grassland hills surrounding the city, and when Diablo wind events push wildfire smoke down from the Diablo Range, the particulates that bypass standard filters settle into ductwork in ways coastal Bay Area cities don’t experience. We’ve cleaned ducts in Gale Ranch, Crow Canyon, and Alcosta, and the pattern is consistent: these large two-story homes have complex multi-zone systems with long supply runs that trap debris for decades.

Air Duct Cleaning Services in San Ramon
Air Duct Cleaning Services in San Ramon address a specific local reality: thousands of homes in Dougherty Valley, Gale Ranch, and Crow Canyon were built between 1985 and 2010 with complex multi-zone duct systems that have never been professionally cleaned. A typical residential cleaning in San Ramon runs $350-$550 for a standard system, with larger homes or those requiring video inspection and air handler service reaching $500-$650. The job involves source removal: dislodging debris at the duct wall with rotary brush agitation, extracting it with negative-air pressure, and filtering the exhausted air through HEPA so particles don’t re-enter your living space.
Residential Duct Cleaning
Most San Ramon homes we clean are 2,500-4,500 square feet with two stories and multiple HVAC zones. The long supply runs to second-floor bedrooms create natural debris traps, especially in homes where builder crews left drywall dust and fiberglass fragments in the ductwork during original construction. We inspect with a camera first, then clean the full system including supply ducts, return ducts, and the air handler.

Commercial Duct Cleaning
San Ramon’s office parks and retail spaces along Bollinger Canyon Road and Crow Canyon Road need scheduled cleaning that doesn’t disrupt business hours. We coordinate after-hours and weekend service, with written pricing agreed before we arrive and the same 365-Day Done Right Promise that covers our residential work.

HVAC Duct Cleaning in San Ramon
HVAC Duct Cleaning in San Ramon means more than vacuuming visible registers. The city’s inland valley position and extreme summer heat load mean systems run harder and longer than coastal Bay Area equivalents, pulling more particulates through the ductwork over time. A full HVAC duct cleaning in San Ramon typically costs $400-$650 when it includes the air handler, blower motor, and all supply and return lines. We use Rotobrush systems to agitate debris at the duct wall, Nikro negative-pressure units to pull it out, and Abatement Technologies HEPA filtration to capture loosened particles before they re-enter your home.
Supply and Return Line Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In San Ramon’s Dougherty Valley homes, we regularly find the first 18 inches of each supply boot packed with compacted drywall dust and insulation particles from the original build. Cleaning only the returns or only the supplies leaves half the problem circulating through your system.
Full System Cleaning with Video Inspection
We run a camera through the ductwork before and after cleaning. For San Ramon homes built during the 2000s Dougherty Valley buildout, this step is essential: the identical builder-grade flex duct layouts across whole streets create predictable failure patterns that a camera reveals immediately. The after-cleaning video confirms the debris is gone.
Trusted Brands We Service in San Ramon
Our technicians work with all major HVAC and filtration equipment found in San Ramon homes. We stock Aprilaire media filters and whole-house air cleaners, Guardsman filtration products, and Abatement Technologies HEPA replacement media for customers who want to maintain clean air between professional cleanings. Most replacement parts are carried on our service vehicles, so if we find a compromised filter housing or damaged flex duct during your cleaning, we can often address it the same visit rather than scheduling a return trip. For homeowners looking to upgrade, we also install Honeywell and Aprilaire indoor-air-quality products designed for the particle loads that San Ramon’s summer dust and wildfire smoke create.
Common Air Duct Cleaning Problems We See in San Ramon Homes
- Builder debris in Dougherty Valley supply boots. Homes built between 2000 and 2010 in Gale Ranch and surrounding subdivisions routinely contain drywall dust and fiberglass fragments compacted in the first 18 inches of each supply boot, untouched since construction because no post-build inspection was required.
- Wildfire smoke infiltration from Diablo wind events. Fall wind patterns push smoke directly into the San Ramon valley, and fine soot and ash particles bypass standard filters to accumulate in ductwork, creating recurring odor and particulate issues that coastal cities don’t experience at the same intensity.
- Long second-floor supply runs trapping dust. San Ramon’s large two-story homes have extended duct runs to upstairs bedrooms, and the combination of continuous summer operation and original construction debris creates dense accumulation zones that shop-vac cleaning can’t reach.
- Ignored air handlers circulating old debris. Many San Ramon homeowners clean the ducts but skip the air handler and blower motor, leaving drywall dust to recirculate through a system that already runs hard through months of 95-105°F heat.

FAQs About Air Duct Cleaning in San Ramon
No, and that’s the problem. California building codes in 2005 did not require post-construction duct cleaning, so builder crews left drywall dust, insulation particles, and construction debris in the flex duct that remains there today. We recommend a professional cleaning with camera inspection for any Dougherty Valley home built between 2000 and 2010 that hasn’t had one. Call (469) 972-3151 for a free estimate.
San Ramon’s massive Dougherty Valley buildout added thousands of nearly identical two-story homes in the 2000s, and those builder-grade duct systems are now hitting the 15-20-year mark simultaneously. Entire streets share the same original flex duct layouts and the same untouched construction debris. We often book multiple homes on the same block in the same week. Call (469) 972-3151 to schedule your inspection.
Fall Diablo wind events push wildfire smoke directly into San Ramon’s valley position, and fine soot, ash, and combustion debris particles bypass standard HVAC filters to accumulate in ductwork. Coastal Bay Area cities experience this less intensely due to onshore wind patterns. Professional cleaning with HEPA-filtered negative-air extraction removes these particulates from the full system. Call (469) 972-3151 for an assessment after heavy smoke events.
The National Air Duct Cleaners Association (NADCA) Standard 2021 requires source removal of contaminants, protection of the building and HVAC system during cleaning, and proper disposal of debris. For San Ramon’s construction-debris-heavy ductwork, this means brush agitation at the duct wall, negative-pressure extraction, and HEPA filtration, not register-level vacuuming. We follow NADCA procedures on every job. Call (469) 972-3151 to confirm our methods.
Yes, significantly. San Ramon’s 95-105°F summers force months of continuous HVAC operation that pulls fine dust from surrounding dry grasslands into the system; if your ducts already contain builder debris, the airflow distributes that dust throughout the home. Source removal cleaning eliminates the reservoir, and many San Ramon homeowners report visibly less dust on registers within days. Call (469) 972-3151 for a free estimate.
On a Gale Ranch street off Bollinger Canyon Road, we cleaned a 2006-built two-story whose second-floor rooms had run dusty since move-in; a camera inspection showed builder-grade flex duct lined with drywall dust and insulation particles compacted at the supply boots. Using negative pressure, agitation tools, and HEPA filtration, our tech performed source removal across the supply and return ducts and the air handler, and the homeowner reported the fine gray dust on the registers stopped returning within days.
Because San Ramon’s Dougherty Valley homes were built as identical two-story plans across whole streets, many of these builder-grade flex duct systems were never cleaned after construction and now hit the 15-20-year mark simultaneously, so we routinely pull drywall dust and fiberglass fragments from the first 18 inches of every supply boot on a street in the same week. If your San Ramon home was built during the 2000s and has never had a professional duct cleaning, the debris is almost certainly still in there.
