Why Los Altos Homeowners Choose Bellows Air Duct & Vent Co. of California
We’ve built our reputation in Los Altos on showing up when we say and leaving the job done right the first time. Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro professional-grade systems, the same brands serious HVAC contractors specify for their own jobs. Every clean includes camera inspection before and after, so you see what was in your ducts and you see that it’s gone.
Our 90-Day Done Right Promise applies to every Los Altos job we complete, from modest ranch homes near Grant Road to larger properties off Magdalena Avenue. If something isn’t right, we return at no charge with no paperwork required. That’s been our standard since 1984, and it’s why homeowners in neighborhoods like South Los Altos and the Old Mill area call us back when their adult children buy their own homes nearby.
We don’t use bait coupons or surprise pricing. The number we quote on the phone is the number on the invoice, disclosed before a single tool is lifted. Los Altos homeowners have told us they appreciate that directness, especially after past experiences with low-bid operators who found “additional problems” once they were inside the house.
Air Duct Cleaning Services We Offer in Los Altos
Air Duct Cleaning
We clean the complete supply and return duct network, including main trunks, branch lines, and registers, using agitation tools and negative air machines that pull loosened debris out of your system rather than redistributing it. Our process is designed for the original sheet-metal and early flex-duct systems common in 1950s-1970s Los Altos ranch homes, where deteriorating fiberglass duct liner requires careful handling. Learn more about our Air Duct Cleaning in Los Altos.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of house fires nationwide, and Los Altos homes with long vent runs through crawl spaces or exterior walls face elevated risk due to reduced airflow and moisture retention. We remove blockages with rotary brushes and high-velocity air tools, then verify flow rates with anemometer readings before we leave. Learn more about our Dryer Vent Cleaning in Los Altos.
HVAC Cleaning
Beyond ducts, we clean evaporator coils, blower assemblies, and plenums where biological growth and construction dust accumulate in Los Altos systems that have run on recirculate during wildfire smoke events. This service is particularly valuable for homes near Rancho San Antonio Open Space Preserve, where fine particulate infiltration compounds normal household buildup. Learn more about our HVAC Cleaning in Los Altos.
Duct Repair & Sealing
Original ductwork in Los Altos ranch homes often suffers disconnected seams, rodent damage in crawl spaces, and deteriorated flex-duct connections that leak conditioned air into unconditioned spaces. We repair with code-compliant materials and seal with mastic or metal-backed tape, not the failing duct tape many original installers used.
Air Quality & Sanitizing
For homes with documented mold growth, persistent odors, or post-remediation verification needs, we apply EPA-registered sanitizers to duct interiors following thorough mechanical cleaning. We do not sell sanitizing as a standalone service; it follows proper debris removal, not replaces it.
Neighborhoods We Serve in Los Altos
We work throughout Los Altos, from the tree-lined streets of Old Los Altos to the hillside properties of Los Altos Hills. Most appointments are scheduled within two business days, with emergency response available for post-fire-season cleanups and renovation dust remediation.

Why Los Altos’s Climate & Housing Affect Air Duct Cleaning
Los Altos presents a specific set of conditions that make professional duct cleaning more consequential here than in many neighboring communities. The city is almost entirely single-family residential, dominated by 1950s-1970s ranch-style homes whose ductwork runs through unconditioned crawl spaces beneath slab or raised foundations. These crawl spaces accumulate winter moisture, rodent debris, and decades of biological growth that feeds directly into living areas. The mild but damp winters mean crawl-space humidity regularly exceeds 70%, promoting mold colonization on duct exteriors and insulation that homeowners rarely inspect.
The 2018 Camp Fire and 2020 fire season forced prolonged periods of unhealthy air across the Santa Clara Valley, with Los Altos residents running HVAC on recirculate for weeks to avoid wildfire smoke infiltration. That strategy protected immediate indoor air quality but concentrated fine particulate in duct systems, where it remains until mechanically removed. Compounding this, the city’s extreme property values have fueled constant high-end renovations that blast construction dust into aging duct systems left in place during gut remodels. We’ve cleaned ducts in Los Altos homes where the kitchen and baths were fully modernized while the original 1962 ductwork sat undisturbed, collecting decades of accumulated debris.
Ranch homes along the Loyola Corners and South Los Altos corridors frequently show rodent intrusion in crawl-space ductwork, a pattern our techs recognize immediately. Mature landscaping and adjacent open-space foothills of the Rancho San Antonio preserve push mice and rats toward foundations, where they nest inside flex-duct runs and void manufacturer warranties on recently replaced systems. We document this damage with camera inspection and can coordinate repair before the warranty claim window closes.

Every three to five years for typical occupancy, but sooner if you’ve completed renovation work, experienced wildfire smoke infiltration during 2018 or 2020, or notice dust redistribution, musty odors, or worsening allergies. Many Los Altos homes we service haven’t been cleaned in fifteen to twenty years. Call (855) 401-6006 and we’ll help you assess whether you’re due.
Yes. Our technicians are specifically trained for the original sheet-metal and early flex-duct systems common in 1950s-1970s Los Altos construction, where deteriorating fiberglass duct liner requires controlled agitation rather than aggressive brushing. We camera-inspect before cleaning to identify fragile sections, and we adjust our approach accordingly. If we find damage that should be repaired first, we’ll show you and quote repair before proceeding.
Same-day service is often available for respiratory concerns, post-renovation cleanups, and real estate transaction deadlines. Standard appointments typically schedule within 48 hours. Our office answers live 24 hours a day at (855) 401-6006, so you can call anytime to check current availability.
Cleaning is almost always the more economical first step, typically one-third to one-half the cost of partial duct replacement. However, original flex-duct with rodent damage, collapsed sections, or widespread mold on the interior may warrant repair or targeted replacement. We camera-inspect first and show you exactly what we’re seeing, so you can make an informed decision with actual visual evidence rather than a sales pitch. Call (855) 401-6006 to schedule an inspection, estimates are free.
