We’ve been driving out to Martinez from San Francisco for fourteen years, and we know the difference between a routine duct cleaning and what this city actually needs. The Carquinez Strait doesn’t just channel ferries — it channels a steady stream of delta winds straight through your HVAC intake, carrying industrial particulates you won’t find in Walnut Creek or Pleasant Hill. That’s why our HVAC Cleaning team treats Martinez as its own category of job, not a standard suburban service call.
Why Northstar Air Duct Cleaning Service San Francisco Is Martinez’s Preferred HVAC Cleaning Company
Brian Rivera — owner and lead technician — handles your job personally. That means the person with fourteen years of focused air duct and indoor air quality experience is physically on your property, not managing from an office. For Martinez homeowners dealing with refinery-adjacent contamination, this matters. You get someone who recognizes gray-black soot buildup on sight, who knows the sulfur smell that lingers in west-side neighborhoods, and who adjusts the cleaning protocol accordingly.
Our numbers: 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 in Contra Costa County. Martinez customers specifically mention the difference owner-led service makes — no dispatched labor, no rotating crews, just Brian Rivera and professional-grade equipment on every call.
We respond to Martinez within 24–48 hours, sometimes same-day depending on route. We know the parking constraints near downtown Victorian conversions, the narrow driveways in post-war refinery-worker tracts off Alhambra Avenue, and the access issues that come with 1920s bungalows retrofitted with modern HVAC. This local fluency saves you time and prevents the callbacks that happen when a technician treats your 1910 Craftsman like a new-build in San Ramon.
Our HVAC Cleaning Services in Martinez
Evaporator Coil Cleaning
The evaporator coil in your Martinez home works harder than it should. Marine fog from the Carquinez Strait raises indoor humidity, and when that moisture combines with refinery particulates coating the coil, you get a sticky, microbial film that standard cleaning misses. We use Rotobrush contact cleaning paired with Nikro HEPA extraction to remove the contamination, then apply a coil treatment that addresses the petroleum-laced residue unique to this area. A clean coil in Martinez isn’t just about efficiency — it’s about stopping the musty, sulfur-tinged air that recirculates through undersized ductwork in older homes.
Blower Cleaning
Your air handler blower is the first place refinery-related contamination accumulates. We’ve opened blowers in Martinez homes west of Berrellesa Street and found gray-black, oily buildup that generic brushes simply smear around. Our protocol: remove the blower assembly, clean with Rotobrush agitation and Nikro negative-air HEPA containment, then inspect for balance and bearing wear. In the 1910s Craftsman on Berrellesa we recently serviced, the blower alone held over 8 pounds of petroleum-laced dust. After cleaning, the homeowner reported the sulfur smell was gone within hours. That’s the difference between moving air and actually cleaning it.
Condenser Cleaning
Outdoor condensers in Martinez battle a double load: standard pollen and dust, plus the fine particulate fallout from the PBF Energy refinery that settles on coil fins and reduces heat transfer. We clean condenser coils with low-pressure foaming agents and fin combs, never the high-pressure washers that bend aluminum and void warranties. For homes near the refinery fence line, we recommend condenser cleaning as part of annual maintenance — the particulate load here is simply heavier than inland Contra Costa cities, and your system’s efficiency pays the price if you wait until failure.
Air Handler Cleaning
The air handler is where your Martinez home’s air quality battle is won or lost. In retrofitted Victorian and Craftsman bungalows, air handlers are often crammed into closets or basements never designed for HVAC, with flex duct connections that leak and recontaminate constantly. We clean the entire air handler cabinet — housing, drain pan, blower compartment, and return plenum — using Abatement Technologies containment to prevent cross-contamination. Then we seal accessible joints with mastic, because in Martinez’s older housing stock, a clean system with leaky ducts is a system that gets dirty again fast.

Trusted Brands We Service in Martinez
We don’t show up with a shop vac and good intentions. Our trucks carry Rotobrush contact cleaning systems, Nikro negative-air HEPA vacuums, and Abatement Technologies containment equipment — the same tools used in commercial remediation, deployed on your residential job. For sanitizing and odor neutralization after refinery-related cleanings, we use Guardsman-grade treatment products. We stock common replacement parts for Martinez’s most frequent equipment brands, so most jobs don’t require a return visit. When you’ve got sulfur compounds in your ductwork, you want the tool that removes them, not the tool a generalist keeps in a side van.
Common HVAC Cleaning Problems We See in Martinez Homes
- Refinery particulate infiltration: Homes west of Berrellesa Street, closest to the PBF Energy refinery, regularly show gray-black sooty buildup with a faint sulfur odor on registers and blowers. This isn’t ordinary household dust — it’s a petroleum-laced contamination profile that requires specialized agitation and HEPA extraction, not standard vacuuming.
- Marine fog microbial growth: The seasonal marine layer rolling through the Carquinez Strait raises humidity in insulated flex duct enough to promote mold and mildew, especially in post-WWII tract homes with original degrading ductwork. Cleaning without addressing the moisture source means the problem returns within months.
- Leaky retrofitted ductwork: Martinez’s Victorian and Craftsman core neighborhoods feature ductwork installed decades after original construction, often undersized and poorly sealed at joints. We clean what we can access, then seal visible leaks with mastic — because in these homes, recontamination happens faster than in new construction with tight duct systems.
- Odor persistence after generic cleaning: Competitors using standard brushes and no HEPA containment often redistribute refinery-related residues rather than remove them. Homeowners call us after “clean” systems still smell like sulfur. The fix: proper negative-air containment and coil treatment, not a surface wipe.

Call (855) 908-0725 to discuss what we’ve found in homes near your neighborhood.
Most Martinez homes benefit from HVAC cleaning every 2–3 years, but homes west of the refinery fence line or with original post-WWII flex duct should consider annual service. The combination of refinery particulates and marine fog moisture accelerates contamination faster than in drier, inland Contra Costa cities. Call us for a free assessment of your specific system condition.
Yes — sulfur odors in Martinez are typically caused by refinery-related particulates accumulating on the blower and evaporator coil. We remove the contamination with Rotobrush agitation and Nikro HEPA extraction, then apply a coil treatment to neutralize residual odors. In the Berrellesa Street Craftsman we serviced, the smell was eliminated same-day. Call (855) 908-0725 to schedule.
