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 and HVAC cleaning in Hillsborough, CA is a different job than most Bay Area cities because of the housing stock: large custom estates built between the 1950s and 1990s, many with original duct runs sized for older furnaces, set back on heavily landscaped lots. Hillsborough’s eucalyptus and oak canopy means more fine organic dust cycling through returns, and the town’s microclimate – cooler and foggier than the Peninsula flatlands – keeps ducts damp longer each morning. We’re Cardinal Air Duct Cleaning, and we run professional-grade equipment through Hillsborough homes on a written, upfront price. Call (737) 727-2314 for a free estimate on any of our three specialty services.
Why Hillsborough Homes Are Different
Hillsborough was built as an estate town, and the HVAC infrastructure reflects that. Many homes in the lower and middle Hillsborough neighborhoods still run original 1970s and 1980s duct systems – galvanized steel trunk lines with fiberglass wrap, sized generously but now carrying decades of dust, pet dander, and occasionally construction debris from successive remodels. When we run a Nikro HEPA negative-pressure system through those runs, the volume we pull out of a 5,000 square foot Hillsborough home is routinely double what we see in newer Peninsula track housing.
The terrain matters too. Hillsborough lots slope – some steeply. Crawlspace and attic access is often tighter than homeowners expect, and duct runs follow rooflines rather than straight basement lines like you’d find back east. That geometry means cleaning takes longer and tools have to be routed carefully. We plan jobs around access points before sending a tech, so the written price you get reflects the actual house, not a guess. The eucalyptus and pine canopy across town also loads the outdoor air with fine particulates that make their way past older return grilles, which is why Hillsborough homeowners often notice dust settling back on furniture within weeks if the return side is not cleaned along with the supply side.
Our Main Hillsborough Services
Most Hillsborough calls start with two jobs: dryer vents that run long and duct systems original to the home. Here’s how each works in Hillsborough specifically.
Dryer Vent Cleaning in Hillsborough
Hillsborough laundry rooms are often on the second floor or at the back of a deep floor plan, which means dryer vent runs of 15 to 30 feet with multiple elbows. Lint accumulates fast in those bends. We clear the full run with a Rotobrush rotary system, then verify airflow at the exterior termination point before we leave. On Hillsborough homes with stucco exteriors, the termination often exits through a side wall rather than the roof, and that cap gets clogged with landscape debris faster than homeowners expect. Full detail on how we handle Hillsborough dryer vents, including pricing, is on the Dryer Vent Cleaning in Hillsborough page.
Air Duct Cleaning in Hillsborough
A proper air duct cleaning in Hillsborough means cleaning every supply and return run, the main trunk lines, and the plenum boxes, not just vacuuming a few visible registers. We use a HEPA-filtered negative-pressure vacuum system – that means the loosened dust is pulled directly into a sealed Nikro unit rather than blown into your living room. Hillsborough’s older estates often have a mix of rigid metal and flex duct added during remodels, and we handle both. See the full Air Duct Cleaning in Hillsborough page for process detail, equipment specifics, and exact pricing ranges for your home size.
HVAC Cleaning in Hillsborough
HVAC cleaning goes beyond ducts to the mechanicals: the evaporator coil, blower motor, drain pan, and condensate line. In Hillsborough, where many homes run AC only seasonally and heat via gas furnaces, coils can sit damp through the foggy months and accumulate a film that reduces efficiency and shortens equipment life. We clean the coil and blower in place using Abatement Technologies containment where needed, then confirm the drain line clears. The dedicated HVAC Cleaning in Hillsborough page covers the full scope and cost.

Two things push Hillsborough pricing toward the upper end of those ranges: access difficulty on sloping lots and the number of flex-duct branch runs added during remodels, which take longer to clean properly than rigid metal. Every job gets a written price before any work starts, and that number does not change when the tech arrives.

FAQs About Air Duct Cleaning Company in Hillsborough
Most Hillsborough appointments are scheduled within the same week. Because we operate on The Relay Standard, you get a live trackable arrival window before the tech shows up – no four-hour waits. Call (737) 727-2314 during business hours or anytime, since a live person answers 24/7, to get a specific slot for your area.
No. Duct and dryer vent cleaning is interior maintenance work on systems wholly within the home, so it does not require Hillsborough HOA approval or a town permit. If your equipment is on the roof and needs HVAC coil cleaning, our techs can access it directly; no exterior changes are made that would trigger review.
Cheap cleanings usually do the supply side only and skip return runs and the plenum. With Hillsborough’s tree canopy and older return grilles, the return side is where most re-circulated dust originates from. We clean both directions on every job and show you before-and-after photos of your own ducts. Call (737) 727-2314 for a written quote – you’ll know the flat system price before we touch anything.
