Air Duct Cleaning Company in San Lorenzo, CA
San Lorenzo’s mid-century tract homes hide a problem that most owners can’t see from the living room: six decades of dust, debris, and failing ductwork. As a dedicated duct specialist serving San Lorenzo since 2017, Duct Cleaning Dublin handles the full picture of what’s happening inside those walls and crawlspaces. We clean, repair, and protect, because clean ducts and damaged ducts aren’t the same problem. Call (855) 356-4417 when you need someone who treats your duct system as a whole, not just a vacuum pass.
Why San Lorenzo Homes Are Different
San Lorenzo’s housing stock was mostly built in the 1950s and 60s, and the ductwork shows it. Single-story ranch-style tract homes dominate the neighborhoods off Hesperian Boulevard, and many still run on original galvanized steel ducts or early flex duct that predates modern sealing standards. The climate adds its own pressure. Cool, wet winters push moisture into crawlspaces, and that dampness finds its way into ducts, feeding musty odors and mold growth. Dry summers bake the same ductwork, loosening joints and pulling connections apart. We regularly see systems in San Lorenzo that have never been professionally cleaned, with disconnected joints, rodent entry points, and layers of debris packed into corners. In the older tracts near the Alameda County fairgrounds area, the oak trees are part of the story too. Technicians find ducts clogged with acorns and nesting material, particularly where aging crawlspaces leave gaps that animals exploit. Duct cleaning here isn’t a quick vanity service. It’s a restoration job on systems that have been working hard for 60 or more years.

Our Main San Lorenzo Services
San Lorenzo homeowners call us most often for two jobs: clearing decades of buildup out of their ductwork, and clearing the dryer vent before it becomes a fire hazard. Here’s what each involves in this climate and this housing stock.
Air Duct Cleaning in San Lorenzo
Homes in San Lorenzo’s 1950s and 60s tracts carry dust that’s older than most of the people living in them. Our cleaning process uses Rotobrush rotary brush systems and Nikro HEPA-equipped equipment to agitate and extract what’s bonded to the duct walls, not just blow debris around. We also run Abatement Technologies negative-air filtration to keep what we dislodge from re-entering your living space. For homes with whole-house filtration from Aprilaire or Honeywell, we’re familiar with working around those systems without disrupting them. When you need the deep clean, see our dedicated page: Air Duct Cleaning in San Lorenzo.
Dryer Vent Cleaning in San Lorenzo
A dryer vent filled with lint is a fire risk, and in San Lorenzo’s older ranch homes, those vents often run long distances through attics and crawlspaces where lint accumulates at the turns. We treat dryer vent cleaning as its own service with a fire-prevention focus, not a checkbox add-on. Our equipment reaches the full run of the vent, clearing the blockage that restricts airflow and pushes your dryer to work harder.

Air Duct Repair in San Lorenzo
In a San Lorenzo house built in the 1950s or 60s, the ductwork has outlived its expected service life by a wide margin. Original galvanized steel runs are often disconnected at joints, early flex duct sags and tears, and winter moisture from the marine layer accelerates rust and separation in crawlspaces. Cleaning alone won’t fix a system that’s leaking conditioned air into the attic. Our Air Duct Repair service addresses the damage that decades of use, shifting soil, and rodents leave behind, so the air you pay to heat or cool actually reaches the rooms you live in.
HVAC Duct Installation
Signs you need it
Your existing ductwork has collapsed, is rusted through in multiple spots, or the layout was installed decades ago when the house had a different heating and cooling setup.
What it costs in San Lorenzo
Full HVAC duct installation in San Lorenzo typically runs $3,000 to $7,000, depending on the home’s square footage and crawlspace accessibility.
How we do it
We measure every room’s airflow requirements, remove the failed runs, and install new ducts with the joints sealed and tested before we leave.
Air Duct Replacement
Signs you need it
You’re seeing dust blowing from registers despite recent cleaning, or a visual inspection shows crushed flex duct and rust holes in the steel sections.
What it costs in San Lorenzo
Replacing a full system of aging ductwork in San Lorenzo generally falls between $2,500 and $5,500, with partial replacements running lower.
How we do it
We remove the damaged sections or the full system, then install replacement ducts sized to match your current HVAC equipment, sealing every connection and joint.
Ductwork Repair
Signs you need it
Rooms feel uneven in temperature, your energy bill is climbing, or you can hear rattling and feel air escaping from seams in the attic.
What it costs in San Lorenzo
Targeted ductwork repair in San Lorenzo usually costs $350 to $900, depending on how many joints need resealing and how accessible the crew’s work area is.
How we do it
We locate the leaks, reseal joints with mastic and metal tape, support sagging sections, and confirm the airflow at each register reads correctly after the fix.
What Air Duct Repair Costs in San Lorenzo
| Item | Typical range in San Lorenzo |
|---|---|
| Targeted ductwork repair (sealing, reconnecting joints) | $350 – $900 |
| Air duct replacement (full system) | $2,500 – $5,500 |
| HVAC duct installation (new system) | $3,000 – $7,000 |
How long does duct repair take in San Lorenzo?
Most targeted ductwork repairs finish in half a day. Full replacement or new installation typically takes one to two days, depending on crawlspace access and how much of the original system needs to be pulled out.
Can you really fix leaking ducts in a 1950s crawlspace?
Yes. The crawlspaces under San Lorenzo’s ranch homes are tight, but we work in them regularly. We bring the right sealing materials and lighting, and we repair or replace exactly what’s failed without disturbing the rest of the system.

Brands We Service in San Lorenzo

Tight older crawlspaces under 60-year-old ranch homes take more time, and systems with rodent intrusion or disconnected runs cost more to remediate than a simple cleaning. You’ll get one flat price per system agreed to before we start, not a per-vent figure that grows once the van is in your driveway.
