Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning Company in San Marino, CA
Air duct cleaning in San Marino runs $400 – $800 for a typical whole-home system, with most jobs scheduled within a week and completed in one day. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve built our approach around what makes this city’s homes unlike any other in the San Gabriel Valley. San Marino’s architect-designed estates from the 1920s to 1960s carry original gravity and early forced-air systems that demand careful, restoration-minded work rather than rough handling. Call (361) 326-5060 for a free estimate.
Why San Marino Homes Are Different
San Marino’s housing stock is a preservation challenge. Most homes here were built between 1920 and 1970, many by prominent architects of the era, with original plaster walls, hardwood floors, and ductwork that may be wrapped in asbestos or lined with now-degraded materials. The large attics and raised foundations common on streets like Lorain Road and Huntington Drive mean our technicians navigate tight, irregular spaces where ducts have been disconnected or crushed by decades of remodels.
The Santa Ana winds push dust, pollen, and wildfire ash through outdoor air intakes year after year. After the 2020 Bobcat Fire, we found layers of ash in unlined attic ductwork that standard residential vacuums couldn’t touch. The city’s mild climate means HVAC systems run nearly year-round, so debris accumulates faster than in cities with true winter shutdowns. San Marino’s strict architectural review and preservation-minded homeowners also mean we often clean and seal original systems rather than replace them, a constraint rarely seen in neighboring Alhambra or San Gabriel.
Our Main San Marino Services
San Marino homeowners call us most often for these three jobs, each handled with equipment and techniques matched to older, architecturally sensitive homes.
Air Duct Cleaning in San Marino
Our rotary brush systems from Rotobrush and negative-air machines from Nikro loosen and extract decades of buildup from original galvanized or fiberboard ductwork without damaging fragile seams. In San Marino, we regularly encounter gravity systems with no filtration history and forced-air retrofits from the 1950s that were never properly sealed. Every job starts with a written price and ends with before-and-after photos of your own ducts. Air Duct Cleaning in San Marino

Dryer Vent Cleaning in San Marino
Dryer vent cleaning in San Marino often means longer runs through original construction, sometimes routed through walls or under raised foundations that complicate access. Lint accumulation in these older configurations is a genuine fire hazard, and we use rotary brush and high-velocity air tools to clear the full run, not just the accessible sections. We inspect the termination point and airflow before we leave. Dryer Vent Cleaning in San Marino

Duct Sealing in San Marino
Duct sealing in San Marino addresses the disconnected, crushed, and unsealed joints we find in attics and crawl spaces of homes that have seen multiple HVAC retrofits. We apply mastic sealant and mechanical fasteners to restore system pressure without tearing out original plaster or architectural details. For San Marino’s preservation requirements, this approach keeps historic fabric intact while cutting energy waste. Duct Sealing in San Marino
