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 inside some of the largest custom estates on the Peninsula. These are not standard suburban systems. Many homes built between the 1930s and 1970s run original sheet-metal ducts that have been patched, extended, and re-zoned through decades of renovations. That history shapes how we inspect, how we clean, and what we tell you up front. If you need air duct work in Hillsborough, call us at (980) 447-2498 for a written estimate.
Why Hillsborough Homes Are Different
Hillsborough sits in the marine fog belt of the San Francisco Peninsula. High relative humidity lingers through winter and spring, and in a 10,000-square-foot home with guest wings and infrequently conditioned rooms, that moisture finds its way into ductwork. We regularly open returns in Hillsborough and find enough damp accumulated inside to support mold growth. Then late summer brings Diablo wind events that push wildfire smoke across the hills, loading systems with fine particulate that embeds in aged, porous duct liner.
The homes themselves add another layer. Original fiberglass duct liner from the 1950s and 60s delaminates over time, shedding fibers directly into the airstream. Duct runs often pass through unconditioned basement mechanical rooms or sub-floor crawl spaces that cycle between fog-driven moisture and dry heat, which accelerates that breakdown. A standard cleaning crew without experience in Hillsborough will not know to look for this. Our technicians expect it and inspect for it before any cleaning begins.
Our Main Hillsborough Services
Hillsborough homeowners call us most about three jobs: cleaning the full duct system, clearing dryer vents, and repairing aging or damaged duct runs.
Air Duct Cleaning in Hillsborough
Full-system cleaning in Hillsborough means accounting for multi-zone layouts, dead-end duct sections, and original sheet-metal runs that have been extended through several renovation cycles. We use negative-pressure extraction equipment from Nikro to pull debris out rather than blow it around, which matters in homes where duct liner is already fragile. Learn more on our Air Duct Cleaning in Hillsborough page.
Dryer Vent Cleaning in Hillsborough
Dryer vents in Hillsborough estates often run farther than in typical Peninsula homes, sometimes forty feet or more through walls, floors, and crawl spaces. Lint builds up in long runs faster, and the marine fog keeps it damp. We clear the full run and bypass the lint trap with professional equipment. Read about the process on our Dryer Vent Cleaning in Hillsborough page.
Air Duct Repair in Hillsborough
Old duct systems in Hillsborough develop leaks at improperly sealed joints, collapsed sections in crawl spaces, and delaminated liner that needs replacement. We repair what is failing rather than push a full replacement unless the system genuinely needs it. Every repair receives a written guarantee and a free second visit if the repair does not hold. Details are on our Air Duct Repair in Hillsborough page.

FAQs About Air Duct Cleaning Company in Hillsborough
Most Hillsborough jobs can be scheduled within a few business days. Larger estate systems often warrant a longer visit window, so we plan the appointment around the size of the home rather than rush through it.
Interior duct work on your own system typically does not require HOA approval. If exterior vents or roof access are involved, check your specific HOA rules. We can coordinate access with the property manager if needed.
Yes. Older Hillsborough estates sometimes have asbestos-containing duct wrap. If we suspect it, we will stop, identify the material, and recommend a licensed abatement professional before any cleaning begins. Safety comes before schedule.

What Hillsborough Customers Say
"Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E."I liked that I knew who was coming in. Name and photo texted ahead, badge at the door. He was quiet, careful with the furniture, and thorough."
- Cheryl A.
