Our Air Duct Cleaning Services in San Ramon
Residential Duct Cleaning
Most San Ramon homes we service are large two-story tract houses, many 2,500-4,000 square feet with multi-zone HVAC. That square footage means longer duct runs, more return branches, and more places for debris to settle. In Dougherty Valley, where thousands of homes were built between 2003 and 2015, we’re seeing a wave of first-time cleanings as those duct systems hit the 10-18 year mark simultaneously. We use Rotobrush and Nikro equipment sized for residential systems, and we don’t leave until the camera shows clear passage.
Commercial Duct Cleaning
San Ramon’s commercial corridors along Crow Canyon Road and Bishop Ranch host medical offices, retail, and professional buildings with rooftop package units and extensive flex-duct networks. We clean after-hours or weekends to avoid disrupting operations, with the same upfront pricing and camera documentation we provide homeowners.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, but in San Ramon they also push whatever’s collected inside them - fine ash from wildfire seasons, grass pollen from Diablo wind events, and ordinary dust accelerated by 95-105°F summer runtime. We clean every supply branch from the main trunk to the register, with before-and-after video you can watch on our monitor.
Return Duct Cleaning
Return ducts pull air back to the handler, and they’re where we find the heaviest buildup in San Ramon homes. The undersized main trunk-line design common in Dougherty Valley Lennar and Standard Pacific builds creates a predictable pinch point at the air handler that traps debris year after year. Our Air Duct Cleaning team knows to inspect this choke point first, because a return duct half-blocked by a decade of pollen and ash will strain your blower motor and raise your summer bills.
Full System Cleaning
A full system cleaning covers supply ducts, return ducts, the main trunk line, registers, grilles, and the air handler cabinet. In San Ramon, where HVAC systems run harder and longer than coastal cities, this is the service that restores airflow and reduces runtime. Most full system cleans take 4-6 hours and are completed in one visit.
Video Inspection
We camera-inspect every duct system before quoting and after cleaning. In San Ramon’s older homes near downtown, this reveals return-air systems from the 1970s-80s with no cleanout access - a finding that changes our approach entirely. In Dougherty Valley, the camera confirms what we expect: debris trapped at that undersized trunk-line pinch point, sometimes reducing airflow by 20% or more before we start.

Trusted Brands We Service in San Ramon
We clean and service ductwork connected to equipment from Aprilaire, Abatement Technologies, and Rotobrush - brands that serious HVAC contractors specify, not discount operators. We stock common parts and fittings for San Ramon customers, so if our video inspection turns up a disconnected flex-duct or damaged trunk line, we can often repair it same-day instead of scheduling a return trip. No waiting on shipped parts, no second appointment fee.
Common Air Duct Cleaning Problems We See in San Ramon Homes
- Diablo wind deposits in attic intakes. Summer wind events push fine grass pollen and wildfire smoke ash directly into attic-level air intakes. Standard 1-inch filter changes don’t catch what settles inside the ductwork. We remove this coating with powered brushing and HEPA extraction.
- Sagging flex-duct in Dougherty Valley attics. Long horizontal flex-duct runs in unconditioned 94582 attics sag between supports over time, creating low spots where debris collects and airflow stalls. Our video inspection locates these blockages precisely before we cut access.
- Inaccessible return systems in older San Ramon homes. Late-1970s to 1980s homes near the original downtown core were built with return-air plenums that have no cleanout doors. Our crew cuts new access panels where needed, seals them properly after cleaning, and documents the work on camera.
- Synchronized aging across Dougherty Valley subdivisions. Thousands of homes built 2003-2015 share identical duct designs and are now due for first cleaning simultaneously. We’re scheduling full-system cleans street by street in neighborhoods like Windemere and Gale Ranch because the same choke points appear in every third house.

FAQs - Air Duct Cleaning in San Ramon
Every 3-5 years for Dougherty Valley homes, sooner if you’ve had wildfire smoke exposure or notice reduced airflow. That 2003-2015 building cohort is hitting first cleaning now, and the undersized trunk-line design traps debris faster than properly sized systems. If your home’s never been cleaned, schedule a video inspection this season. Call (844) 685-6342 - estimates are free.
Yes, it creates a predictable debris choke point at the air handler that requires specialized brushing to clear properly. Our technicians know the Lennar, Standard Pacific, and Shea floor plans by sight, so we arrive with the right tools and don’t waste time mapping your system. The access is standard; the buildup pattern is what we’ve learned to expect. Call (844) 685-6342 to schedule.
Yes, typically 10-20% when ducts were significantly blocked. San Ramon’s 95-105°F summers already force systems to run longer than coastal cities; restricted airflow makes them run longer still. During a spring cleaning in Dougherty Valley, our crew used a Rotobrush system to clear a Lennar-built home’s main trunk line of a decade-plus of fine ash and pollen - trapped at the predictable pinch point near the air handler - restoring airflow and reducing the system’s runtime by 15%. Your results depend on how blocked your system is; we’ll show you on camera before you decide. Call (844) 685-6342 for a free inspection.
A full system cleaning covers both, and that’s what we recommend for San Ramon homes. Return ducts collect the heaviest buildup; supply ducts distribute whatever’s left. Cleaning only one leaves half the problem. If budget is tight, start with the return side and the main trunk line, then schedule supply cleaning within six months. We’ll quote both options upfront. Call (844) 685-6342.
Proper support spacing and periodic inspection. Flex-duct should be supported every 4-5 feet with strapping that doesn’t compress the insulation; many Dougherty Valley installs used wider spacing that sags over time. During our full system cleaning, we note support issues on camera and can add straps where needed. Annual HVAC tune-ups - ours are $89 - include a visual duct check that catches sagging before it blocks airflow. Call (844) 685-6342 to schedule.
