Fast, Reliable Air Duct Cleaning Across San Lorenzo
Air duct cleaning in San Lorenzo typically runs $450 – $850 for a full system on a single-story ranch home, and the job takes about 4 – 6 hours with professional-grade equipment. If your ducts haven’t been opened up since the Eisenhower administration, you’re probably circulating decades of accumulated dust, oak debris, and crawlspace odors through every room. We work throughout the 94580 zip code and know these mid-century tracts well. Our crews understand what’s hiding in San Lorenzo ductwork because we’ve seen it hundreds of times. Call (855) 356-4417 for a straight answer and a free estimate.
Why Duct Cleaning Dublin Is San Lorenzo’s Preferred Air Duct Cleaning Company
We’re a dedicated duct and vent specialist, not a generalist HVAC shop that offers duct cleaning as a side item. The equipment we run on every San Lorenzo job includes Rotobrush rotary brush systems and Nikro HEPA-equipped platforms, plus Abatement Technologies negative-air filtration for proper containment. That means we agitate debris off duct walls and extract it under negative pressure rather than blowing it around with a shop vac. Teddy Rhodes built this company around the idea that older housing stock deserves remediation-level attention, not a coupon crew with a truck-mounted vacuum and a 45-minute schedule. Homeowners off Hesperian Boulevard and around the fairgrounds area call us because we scope the job to the actual condition of their ducts, including the disconnected joints and rodent entry points that define older San Lorenzo homes.
Our Air Duct Cleaning team has worked in enough 1950s – 60s tract homes here to know what the original galvanized steel and early flex duct looks like after sixty-plus years. We coordinate directly with San Lorenzo homeowners, walk through what we find, and show you before-and-after photos of your own ducts. One flat price per system is agreed before work starts. No per-vent pricing, no bait-and-switch invoice once the van is parked. That’s the model that has kept San Lorenzo customers calling us back.

Residential Air Duct Cleaning in San Lorenzo
Residential Air Duct Cleaning in San Lorenzo means dealing with duct systems that predate modern filtration standards and have often never seen a professional cleaning in their service life. Many of these ranch-style tract houses still run original rigid metal ductwork through attics and crawlspaces, with early flex runs that have sagged, disconnected, or been chewed through by rodents. A typical full-system cleaning for a three-bedroom San Lorenzo home runs $450 – $750, with larger homes or systems with significant debris loading pushing toward $850. The job includes supply and return duct cleaning, full system cleaning, and video inspection of the runs we can access.
We recommend residential cleaning every 3 – 5 years for most San Lorenzo homes, but homes with heavy oak canopy coverage or known rodent activity may need attention every 2 – 3 years. The interval isn’t arbitrary. It’s set by what actually accumulates in ducts here: acorns, nesting material, dust from unpaved shoulders, and the fine particulate that settles into original ductwork over decades.
Supply and Return Duct Cleaning
We clean both supply and return sides as separate systems, because they collect different debris loads. Return ducts pull air from the living space and often show more dust, pet hair, and fabric fiber. Supply ducts distribute conditioned air back through the home and can hold construction debris, rodent nesting material, and acorns that fell into the system through disconnected joints or open registers in the crawlspace.
Full System Cleaning with Video Inspection
Every full system cleaning includes video inspection before and after, because you deserve to see what was actually removed. In the older tracts off Hesperian Boulevard, we routinely document disconnected joints and debris accumulations that a basic duct cleaning crew would miss entirely. The camera tells the story, and the photos go to you after the job.
Commercial Air Duct Cleaning in San Lorenzo
Commercial Air Duct Cleaning in San Lorenzo covers retail spaces, offices, and small commercial buildings throughout the 94580 area, including properties near Hesperian Boulevard and the industrial edges of the unincorporated community. Pricing for commercial duct cleaning runs $1,200 – $3,500 depending on square footage, number of rooftop units, and duct accessibility. We work early in the morning or on Sundays where the building’s schedule demands it, and we provide the same video documentation we give residential customers.
Commercial kitchens and food-service operations near the fairgrounds area face a different contaminant load than offices. Grease vapor, flour dust, and organic debris accumulate in exhaust ducting and HVAC returns faster than in a residence. We scope commercial jobs with the same remediation mindset: negative-pressure containment with Abatement Technologies equipment, agitation with Rotobrush or Nikro platforms, and complete documentation of what we removed.
Return and Supply Duct Cleaning for Commercial Spaces
Return duct cleaning in commercial buildings is often the highest-yield work, because returns draw air from occupied spaces and concentrate whatever’s in that environment. In an older building, that can include decades of dust, degraded insulation, and material from previous tenant improvements. We clean both supply and return runs, and we document everything.
Video Inspection for Commercial Properties
If you own or manage a commercial property in San Lorenzo, video inspection gives you the evidence to show tenants, buyers, or inspectors exactly what was in the system and what it looked like after cleaning. It’s particularly useful in real estate transactions, where a failed HVAC inspection can delay a sale. We provide before-and-after camera footage as part of the job, not as an add-on.
Trusted Brands We Service in San Lorenzo
If your San Lorenzo home has a Honeywell whole-home filtration system or an Aprilaire humidifier or dehumidifier, we’re familiar with how those units integrate into the ductwork and what needs to happen during cleaning to avoid damaging them. Duct cleaning is not a generic process when a home has whole-house air quality equipment. The access points, the filter housings, the sensor locations, and the airflow characteristics all change how we approach the job. Our crews know Honeywell and Aprilaire systems well enough to clean around them without disrupting calibration or performance. We’ll also flag if your whole-home filter is past its service interval, because cleaning the ducts and leaving a clogged Aprilaire filter in place is a wasted trip.

AfterCommon Air Duct Cleaning Problems We See in San Lorenzo Homes
- Acorns and oak nesting material in duct runs. The mature oak canopy off Hesperian Boulevard and throughout older San Lorenzo tracts drops acorns that rodents carry into crawlspaces. We’ve pulled return registers and found flex runs packed with acorns and shredded material that block airflow and grind dust into the system every time the blower kicks on.
- Disconnected joints on original galvanized ductwork. Sixty-year-old ducts in San Lorenzo crawlspaces routinely show separated seams and joints where the original fasteners have corroded or worked loose. The system ends up pulling crawlspace air, moisture, and debris into the conditioned space. Cleaning alone doesn’t fix this; it takes sealing and repair.
- Rodent entry points in aging crawlspaces. The combination of older pier-and-beam foundations and abundant ground cover gives rodents access to San Lorenzo crawlspaces year-round. We find gnawed flex duct, nesting material, and droppings in systems that haven’t been opened up in decades. The ducts get cleaned, but if the entry point isn’t addressed, the problem returns within a season.
- Musty odors after winter rains. San Lorenzo’s wet winters and damp crawlspaces leave duct systems holding moisture that a dry-only cleaning schedule never addresses. Oak debris absorbs water, the crawlspace air stays humid, and the smell transfers into the home through compromised ducts. A seasonal cleaning that includes checking for moisture intrusion is the only way to keep the musty smell from coming back.
On a ranch-style tract off Hesperian Boulevard, our tech pulled a return register and found the flex run loaded with acorns and shredded oak nesting material, with a disconnected joint dumping air into the crawlspace. We set up negative pressure with HEPA filtration, ran agitation tools through the supply and return ducts, sealed the joint, and camera-inspected the run before buttoning it back up. The blower motor drew noticeably cleaner afterward.
Pricing for Air Duct Cleaning in San Lorenzo, CA
A full residential Air Duct Cleaning job in San Lorenzo runs $450 – $850 for a typical single-story ranch home. Smaller systems or lighter debris loads land at the lower end. Homes with significant wildlife debris, disconnected ducts needing sealing, or multiple runs across a large footprint push toward the top of the range. Commercial jobs run $1,200 – $3,500. What affects the price is not square footage alone; it’s the condition of the ducts, the time required to properly clean them, and whether repair work like joint sealing is needed. We agree on one flat price per system before any work starts. Call (855) 356-4417 and we’ll give you a straight quote based on your home type and what we expect to find in the system.

FAQs About Air Duct Cleaning in San Lorenzo
Most San Lorenzo ranch homes with original galvanized steel or early flex duct should be cleaned every 3 – 5 years. If your property has heavy oak canopy and known rodent pressure from the crawlspace, clean every 2 – 3 years. The interval is driven by what actually builds up in these older systems, which in this area means acorns, nesting material, dust from unpaved shoulders, and the fine particulate that has accumulated over decades. Call (855) 356-4417 and we’ll scope your specific situation with a free estimate.
Yes. Homes that burn wood anywhere in the system pull fine ash and particulate into the return ducts, and if the wood stove or fireplace shares air with the HVAC system, the loading rate in the ductwork goes up meaningfully. In San Lorenzo’s older tracts, where wood-burning fireplaces exist alongside original ductwork, we recommend inspection at the 2 – 3 year mark rather than waiting for the 5-year interval. Ash is abrasive to blower motors and settles heavily in return runs. A walkthrough and camera inspection will tell you exactly what’s in your system. Call (855) 356-4417 for a free estimate.
Sometimes, and in San Lorenzo it’s more likely than not tied to the ducts. Winter rains saturate the soil under pier-and-beam crawlspaces, and the moisture rises into the duct system through disconnected joints, unsealed seams, and corroded vent holes. The musty smell you notice is often crawlspace air being pulled into the supply side and distributed through the home. A cleaning that only addresses dust won’t touch this. The fix involves checking for joint separation, addressing the moisture source where possible, and cleaning the ducts with proper filtration. Call (855) 356-4417 for an inspection and quote.
For older San Lorenzo homes, duct cleaning involves more than vacuuming out dust. We run Rotobrush rotary brush systems and Nikro HEPA platforms through both supply and return runs to agitate and extract debris, set up Abatement Technologies negative-air containment to keep the work contained, seal disconnected joints we find, and camera-inspect the runs before and after. In homes with original galvanized ductwork, we look specifically for joint separation and rodent entry points, because those are the failure modes that define this housing stock. You get before-and-after video of your own ducts, not a generic invoice. Call (855) 356-4417 for a free estimate.
Yes. We run Nikro HEPA-equipped equipment on every residential job, and Abatement Technologies negative-air systems provide filtration during cleaning so debris doesn’t recirculate into your living space. We also check your existing filter setup and will tell you if the MERV rating is appropriate for your system. San Lorenzo homes with Honeywell or Aprilaire whole-house filtration get special attention, because the access points and filter housings need to be worked around carefully. If your filter is clogged or the wrong rating, we’ll flag it before we leave. Call (855) 356-4417 and we’ll walk you through what to expect.
