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 Hillsborough, CA
Air duct cleaning in Hillsborough means working on homes where the ductwork was installed when the house was built, then extended and rerouted through multiple renovations over 40 or 50 years. Most jobs in Hillsborough run between $400 and $800 for a full system, depending on square footage and how many returns and supplies the house has. We’re a local duct cleaning company that gives every homeowner a written price before work starts, and we back the job with our 365-Day Done Right Promise in writing. Call (469) 972-3151 for a free estimate.
Why Hillsborough Homes Are Different
Hillsborough is zoned exclusively for large single-family estates, no apartments, no commercial buildings, so every air duct job here involves custom-designed HVAC systems in homes that run from 4,000 to well over 10,000 square feet. Many of these 1930s to 1970s estates have been remodeled several times, which leaves hybrid duct systems: original galvanized sheet metal trunk lines joined to newer flex duct added during additions. That mix creates accumulation points and airflow dead zones you simply won’t find in a standard suburban home.
The fog makes it worse. Hillsborough sits on the inland-facing Peninsula hills but stays inside the Bay Area’s marine-layer belt, so overnight and morning humidity routinely pushes above 80%. That moisture wicks into crawl-space duct sections under hillside foundations, and in older uninsulated metal ducts it promotes mold and microbial growth in a way less common in drier spots like San Carlos or Redwood City. Technicians working pre-1970 Hillsborough homes also regularly encounter original duct insulation that may contain asbestos, particularly on older furnace plenums and supply trunk lines. That means a pre-cleaning assessment step is the norm here, not an optional add-on.
Our Main Hillsborough Services
Hillsborough homeowners call us most often for two jobs: full air duct cleaning for those sprawling multi-wing systems, and dryer vent cleaning for laundry rooms that are often tucked into older additions with long, winding vent runs.
Air Duct Cleaning in Hillsborough
Hillsborough duct systems are long, branched, and often run through unconditioned crawl spaces beneath hillside foundations. That combination means debris settles in sections most homeowners never see, and the marine-layer humidity can turn that debris into a damp, compacted layer inside the duct wall. We use Rotobrush rotary brush systems to dislodge debris at the duct wall and Nikro negative-pressure units to pull contaminants out as we work. Full details are on the Air Duct Cleaning in Hillsborough page.
Dryer Vent Cleaning in Hillsborough
Dryer vents in Hillsborough often run longer than code allows in newer construction because many laundry rooms were added decades after the home was built, pushing the vent through a maze of walls and crawl spaces. Lint collects faster in those long runs, and the fog-belt humidity turns it into a dense plug that restricts airflow and raises dryer temperatures. Every Hillsborough dryer vent cleaning includes a lint trap bypass check and a full run from dryer to exterior termination. Read the specifics on the Dryer Vent Cleaning in Hillsborough page.

What Hillsborough Customers Say
"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
