We’ve been driving out to San Ramon from our San Francisco base for years, and we’ve learned the Tri-Valley climate patterns by heart — the 100°F+ stretches that push your system nonstop, the wildfire smoke that finds its way into return-air intakes, the way builder-grade flex ductwork in those 2000s tract homes starts failing all at once. Brian Rivera — owner and lead technician — handles your job personally. That means the person with 14 years of focused air duct experience is the one running the brushes, not some subcontractor you can’t verify.

San Ramon homeowners research before they book. We respect that. Here’s what you’ll find when you look us up: 1,209 verified reviews averaging 4.9 stars. That’s not a marketing number — it’s a track record across real jobs, many of them right here in the 94582 and 94583 ZIP codes.
Brian Rivera serves as both owner and lead technician, so the most experienced person in our company is physically on your job. We’ve cleaned systems on Corrida Way in Windemere, on the Gale Ranch slopes, and throughout the Dougherty Valley corridors. We know which San Ramon subdivisions share identical builder-grade duct layouts, and we adjust our cleaning protocol accordingly.
Our HVAC Cleaning team carries truck-mounted negative pressure systems rated at 15,000+ CFM — the power needed for San Ramon’s deep two-story flex-duct runs. Generalist HVAC companies often show up with portable units that leave debris in low spots. We don’t.
Response time to San Ramon is typically next-day, sometimes same-day if you’re near the 680 corridor and we’re already in the Tri-Valley. We don’t charge extra for the drive from San Francisco. The estimate is free, and it’s itemized.
Our HVAC Cleaning Services in San Ramon
Evaporator Coil Cleaning
San Ramon’s inland heat means your evaporator coil works harder than coastal Bay Area systems. In a 2005-built tract home on Corrida Way in Windemere, we recently pulled a 2-inch mat of fibrous debris off a coil that had never been cleaned — the original flex ductwork had been dumping construction dust and wildfire ash into the system for 19 years. Our Rotobrush system and coil-specific foaming agents restored heat transfer efficiency. Typical evaporator coil cleaning in San Ramon runs $180–$340.
Air Handler Cleaning
The air handler is where San Ramon’s wildfire ash problem becomes visible. After Diablo Range fire events, fine ash settles in the first 6 feet of return ducts near the handler, then gets blown through the entire distribution system. We disassemble and clean blower assemblies, filter racks, and plenum connections — not a surface wipe, but a full decontamination. Air handler cleaning in San Ramon typically costs $220–$380, with coil treatment bundled at $320–$480.
Blower Cleaning
San Ramon’s two-story zoned systems push blowers to their limit. The long flex-duct runs in Gale Ranch homes create static pressure that strains blower motors and traps debris in the wheel assembly. We remove the blower housing, clean the squirrel cage and motor housing with Nikro contact vacuums, and verify amp draw before reassembly. A dirty blower in a 3,200-square-foot Windemere home can cost you 20% in efficiency. Blower cleaning runs $160–$280.
Condenser Cleaning
Tri-Valley dust and the pollen from San Ramon’s hillside oak and bay laurel populations coat condenser fins aggressively. We use low-pressure foaming agents and fin combs — never high-pressure washers that bend the aluminum. Condenser cleaning is $140–$240 as a standalone, or bundled with full HVAC cleaning.
Heat Exchanger Cleaning
For San Ramon’s gas furnace systems — common in the 1990s builds around Crow Canyon Road — heat exchanger inspection and cleaning is a safety-critical service. We use borescope cameras to inspect for cracks or corrosion, then clean with Abatement Technologies contact tools. This service starts at $260–$420 and includes combustion analysis.
Coil Treatment
After mechanical cleaning, we apply Guardsman-grade antimicrobial treatments to evaporator and condenser coils. In San Ramon’s humidity spikes — when the Delta breeze pushes moisture up the 680 corridor — this prevents mold colonization in the drain pan and on the coil face. Coil treatment as an add-on runs $80–$140; bundled with coil cleaning, it’s $320–$480 total.

Trusted Brands We Service in San Ramon
We don’t show up with generic tools and hope for the best. Our Rotobrush and Nikro cleaning systems are the same units used in commercial remediation jobs — not the lightweight portables a generalist HVAC company keeps in a side van. For air quality solutions after cleaning, we stock Honeywell and Aprilaire media filters and UV systems, with Guardsman treatments for antimicrobial protection. We carry common Aprilaire filter sizes for San Ramon’s newer homes, so replacement happens same-visit rather than ordering and returning.
Common HVAC Cleaning Problems We See in San Ramon Homes
- Skipping lateral branch cleaning in two-story homes: Long flex runs on the upper floor of Gale Ranch houses often trap debris that a main-trunk-only cleaning misses. We’ve been called back after other cleaners left upper-floor registers barely flowing. Our truck-mounted system reaches every branch.
- Using insufficient negative pressure: Many San Ramon 1990s-built homes have complex duct layouts where a weak vacuum leaves debris in low spots. Only a truck-mounted system with 15,000+ CFM pulls everything through these deep two-story runs. Portable units fail here.
- Ignoring the wildfire ash layer: After Diablo Range fire events, fine ash settles in the first 6 feet of return ducts near the air handler. Cleaners who only do supply-side work leave this PM2.5-laden residue in your system. We clean both sides, every time.
- Treating all San Ramon homes as identical: A 1987 build near Crow Canyon has galvanized ductwork with entirely different failure modes than a 2004 Gale Ranch home with flex duct. We inspect before we quote, and we adapt the protocol.

FAQs — HVAC Cleaning in San Ramon
Every 3–5 years for a 2002 Windemere home, with HVAC cleaning every 2–3 years given the original flex ductwork is now past the 20-year mark. The Tri-Valley heat and wildfire exposure accelerate debris accumulation compared to coastal Bay Area homes. If you’ve never had it cleaned, you’re likely overdue. Call (855) 908-0725 for a free inspection — we’ll show you what’s in there.
Yes — a contaminated coil can reduce cooling capacity by 15–30%, which you’ll feel on 100°F San Ramon afternoons when your upstairs zones never reach setpoint. We measure temperature split before and after cleaning, so you see the improvement. The 2-inch debris mat we pulled from that Corrida Way coil? That homeowner’s cooling recovery time dropped measurably. Call (855) 908-0725 to schedule.
Yes — Rotobrush is our primary mechanical cleaning system for San Ramon’s flex-duct homes, including the long runs typical of 2005 Gale Ranch builds. We pair it with Nikro contact vacuums and truck-mounted negative pressure for extraction. The combination handles the debris volume in 20-year-old original ductwork without damaging the flex material. Brian Rivera selects the tool configuration for each job personally.
If you ran your HVAC during or immediately after a Diablo Range smoke event, yes — schedule inspection within 1–2 weeks. Fine ash and PM2.5 particles enter through return-air intakes and settle deep in the system, particularly in the first 6 feet of return duct near the air handler. This residue recirculates until physically removed. We prioritize post-fire cleanings for San Ramon residents. Call (855) 908-0725.
We stock Aprilaire and Honeywell media filters in common San Ramon sizes, with MERV ratings matched to your system capacity. Oversized filters in high-static-pressure flex-duct systems — common in Windemere and Gale Ranch homes — can actually reduce airflow and strain the blower. We measure static pressure before recommending a filter grade. Installation is same-visit with no return trip.
