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.

AfterAir Duct Cleaning Company in Portola Valley, CA
Air duct cleaning in Portola Valley runs $425 – $685 for a typical single system home, with whole-home HVAC cleaning between $575 – $875. The big variable here isn’t square footage, it’s terrain and age of the house. Lots of Portola Valley homes sit on hillsides with long duct runs and older systems, which means more buildup and longer jobs than a flat Peninsula lot. If you want a written price before we touch a single duct, call (737) 727-2314.
Why Portola Valley Homes Are Different
Portola Valley’s mix of 1960s and 1970s ranchers alongside newer custom builds on the western slopes means no two duct systems look alike. The older stock, particularly in the Westridge and Los Trancos Woods areas, often has original metal ductwork with failing seals and decades of accumulated dust. Homes near Portola Road and Alpine Road deal with the same reality: the surrounding oak woodland means fine pollen and leaf debris get pulled into returns every spring and fall. That matters because a standard cleaning on a newer tract home in Menlo Park does not prepare you for what’s actually inside a 50-year-old duct run on a Portola Valley hillside. It changes the tools we bring, the time it takes, and how we sequence the job. It also means we are more aggressive about sealing bypasses while the system is open. The climate plays a role too. Dry summers and wet winters create a cycle where ducts expand, contract, and pull in dust from crawlspaces and garages. That’s not something you fix with a quick shop-vac pass.
Our Main Portola Valley Services
The two jobs Portola Valley homeowners call about most are dryer vent cleaning and whole-home air duct cleaning, with HVAC cleaning running a very close third. Here is what each one involves when the house sits on a hillside rather than a flat lot.
Dryer Vent Cleaning in Portola Valley
Dryer vents in Portola Valley regularly run 15 to 30 feet, especially when a laundry room sits mid-house and the vent exits through a side wall or roofline. That distance is a problem because lint accumulates fastest where the vent turns or rises. We run a rotary brush from both ends, then verify the airflow with a meter rather than guessing. If your dryer takes two cycles to finish a load, there is a real restriction somewhere. See how we handle it on the dedicated Dryer Vent Cleaning in Portola Valley page.
Air Duct Cleaning in Portola Valley
Full duct cleaning here means getting into every branch, not just the mains near the furnace. We use a Rotobrush rotary brush system to loosen debris in the duct walls, then a Nikro HEPA-rated negative-pressure vacuum pulls it out of the house entirely. Negative pressure means the loosened debris goes straight into the vacuum, not back into your living room. Older Portola Valley homes with crawlspace returns pick up far more dust than you would expect. See what a standard job covers on the Air Duct Cleaning in Portola Valley page.
HVAC Cleaning in Portola Valley
HVAC cleaning goes past the ducts into the components that move the air: coils, blower motor, and drain pan. On a Portola Valley hillside, dust plus pine needle debris plus the occasional rodent intrusion makes the coil the dirtiest part of the system. We inspect everything with a camera first, show you what we find, and clean what needs cleaning, nothing more. When the coil is caked, your system runs longer and costs more to operate. The full breakdown is on the HVAC Cleaning in Portola Valley page.
