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, CA typically runs $400 – $800 for a whole-home system, with most jobs scheduled within a week and completed in a single day. We dispatch crews from our San Francisco Bay Area office to serve Hillsborough’s large wooded estates, where leaf litter, pollen, and wildfire ash create duct contamination patterns unlike anywhere else on the Peninsula. If you’re noticing musty odors after fall storms or reduced airflow in older wings of your home, call us at (361) 326-5060 for a free written estimate.
Why Hillsborough Homes Are Different
Hillsborough sits on the Peninsula as a deliberately low-density town, and nearly every property rests on a wooded lot crowded with mature oaks, redwoods, and eucalyptus. That tree canopy is the defining factor for our work here. Fall and winter storms drive damp leaf litter and roof debris into outdoor intakes, while spring pollen loads run higher than in sunnier, flatter Peninsula towns. Summer and fall wildfire seasons add ash and fine smoke particulate that infiltrates return ducts.
The housing stock compounds this. Most homes are large single-family estates, many 3,000 to 10,000-plus square feet, built from the 1920s through the 2000s with architectural variety that reflects each era. We regularly find original galvanized or flex ducting in older wings paired with modern rigid ducting in additions. Long duct runs through attics and crawlspaces are common, and many estates run multiple HVAC zones. That means we often coordinate with estate managers and inspect for disconnected or crushed runs that aren’t visible from the registers.
The hilly terrain and mature canopy also mean access challenges. Crawlspaces can be tight, attics can be extensive, and outdoor units may sit on slopes where debris accumulates faster than on flat lots. We plan for this on every Hillsborough job.
Our Main Hillsborough Services
Most Hillsborough homeowners call us for one of three services. Each has its own page with detailed pricing and local specifics.
Air Duct Cleaning in Hillsborough
We clean the full supply and return duct network using a rotary brush system to dislodge debris, followed by negative-air extraction to pull it out of the home. In Hillsborough, this often means addressing pollen compaction in long flex runs and ash residue from wildfire season that standard vacuum methods won’t touch. We inspect every zone for disconnected ducts before we seal the system back up. Air Duct Cleaning in Hillsborough has full pricing and scheduling details.
Dryer Vent Cleaning in Hillsborough
Dryer vent cleaning removes lint buildup from the duct running between your dryer and exterior vent cap. Hillsborough’s larger homes often have longer vent runs, sometimes 25 feet or more through walls and attic spaces, where lint accumulates in bends and low-slope sections. We use rotary brushes and high-velocity air tools to clear the full run and verify airflow at the termination. Dryer Vent Cleaning in Hillsborough covers local fire-safety considerations and pricing.
Duct Sealing in Hillsborough
Duct sealing closes leaks in the duct network using mastic sealant and metal-backed tape, applied at joints and connections. In Hillsborough’s older estates, we find significant leakage at original galvanized connections and at transition points where additions meet original construction. Sealing these leaks improves airflow to distant rooms and reduces the load on multi-zone systems. Duct Sealing in Hillsborough explains our inspection process and pricing.

What pushes Hillsborough prices toward the higher end: multiple HVAC zones, long duct runs through attic or crawlspace, access difficulty on sloped lots, and the need to coordinate with estate staff or property managers. What keeps them predictable: we write the price before touching equipment, and that number does not move at the door. No per-vent add-ons, no surprise charges for “extra” returns.
