Why San Lorenzo Homes Are Different

San Lorenzo was built out largely as a postwar suburb, which means the ductwork in most homes here is original to the structure or close to it. Galvanized steel ducts from that era hold up structurally, but the joints were sealed with materials that dry and crack over 60 years. When that happens, the system pulls air from the crawlspace or attic instead of the return vents, and that’s why San Lorenzo homeowners often find a fine layer of dust on furniture within days of cleaning the house. Homes near the San Lorenzo Creek corridor and the flatter streets west of Hesperian Boulevard deal with seasonal pollen from the surrounding hills, while the eastern side closer to the Hayward border picks up more freeway particulates from I-880 and Hesperian traffic. The climate here is mild and dry most of the year, but coastal fog pushes in during summer mornings, and that moisture cycle is exactly what makes dust cling to duct walls rather than blow through. Most San Lorenzo homes also sit on crawlspace foundations, and when the duct boots aren’t sealed, whatever is in that crawlspace – dust, rodent traces, old insulation – becomes part of the indoor air. It’s a specific set of conditions we see over and over in this city, and it changes how we approach the job.

Our Main San Lorenzo Services

San Lorenzo homeowners call us most often for two things: dryer vent cleaning and full air duct cleaning, with HVAC coil and blower cleaning close behind. Each service has its own San Lorenzo page with pricing and local details.

Dryer Vent Cleaning in San Lorenzo

Dryer vents in San Lorenzo ranch homes often run longer than modern code allows, with multiple elbows through the attic or under the house. Lint accumulates faster in these runs, and with the dry summers we get here, that lint is a genuine fire risk. We clean the full vent run from the dryer connection to the exterior termination using a Rotobrush rotary system paired with a Nikro HEPA vacuum, so the loosened debris is pulled out of the home rather than blown into it. We also check the vent cap and termination screen, which in older San Lorenzo homes is often painted shut or missing entirely. Full details and local pricing are on the Dryer Vent Cleaning in San Lorenzo page.

Air Duct Cleaning in San Lorenzo

Air duct cleaning in San Lorenzo starts with negative-pressure extraction, meaning the system is placed under vacuum while we agitate the duct walls with a rotary brush, and the loosened debris goes directly into the HEPA-filtered vacuum instead of back into your living room. We clean every supply and return run, the registers, the trunk lines, and the plenums. In many San Lorenzo homes, the return path is an open stud cavity called a panned return, and those collect dust the same way the round ducts do. Pricing, what to expect, and a full breakdown of the process are on the Air Duct Cleaning in San Lorenzo page.

HVAC Cleaning in San Lorenzo

HVAC cleaning in San Lorenzo covers the parts of your system that sit outside the ductwork but inside the airflow: the evaporator coil, blower wheel, blower housing, and the condensate drain pan and line. After years of cycling dust and humidity from the Bay’s summer fog, these components in San Lorenzo systems are often coated with a gray film that reduces airflow and forces the system to run longer. That film is also where mold tends to start when the evaporator coil drips all summer. We clean the coil and blower in place, treat the pan, and flush the drain line so condensate flows freely. See the full scope and San Lorenzo pricing on the HVAC Cleaning in San Lorenzo page.
