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.
Air Duct Cleaning Company in Cupertino, CA
Air duct cleaning in Cupertino most often comes down to one thing: homes built between 1955 and 1985 with original ductwork that has absorbed decades of wildfire smoke, renovation dust, and pollen. We’re Kestrel Air Duct Cleaning, and we clean those systems thoroughly, with a written price in your hands before any work begins. If you’ve been watching your Purple Air sensor spike while your HVAC runs, or you just found drywall dust inside a supply register after a remodel, call us at (469) 972-3151 and we’ll tell you exactly what it will cost.
Why Cupertino Homes Are Different
Cupertino’s housing stock is dominated by 1,200 to 2,100 square foot ranch homes built between 1955 and 1985. Most still run on their original sheet-metal trunk lines, with early flex-duct branches that were never designed for the kind of continuous HVAC use we see now. Homeowners in Monta Vista and the streets off Stevens Creek Boulevard have added permitted ADUs and bonus rooms over the years, and those additions usually tie new supply runs directly into the original 1960s trunk. The result: metal shavings and drywall dust in the main plenum that almost nobody re-inspects after the permit closes.
Then there’s the geography. Cupertino sits right at the base of the Santa Cruz Mountains, which means smoke from events like the 2020 CZU Lightning Complex rolled straight into residential neighborhoods. People ran their HVAC systems for weeks with windows sealed. Fine particulate settled deep inside duct walls and return-air plenums. The dry summers add oak pollen and grass-fire ash from foothill open spaces like Rancho San Antonio Preserve, season after season. A lot of our Cupertino customers already know their air quality numbers before they call us. That’s a homeowner we can work with.
Our Main Cupertino Services
Cupertino homeowners call us for two things, both of which are linked to the age of the homes and the reality of living against the foothills. Each service has its own Cupertino page where you’ll find pricing and a full breakdown.
Air Duct Cleaning in Cupertino
This is a full-system cleaning of your supply and return ductwork, using negative-air extraction (a HEPA-filtered vacuum pulls air through the ducts under negative pressure) and rotary brush agitation (a motorized brush scrubs debris loose from duct walls). In Cupertino we regularly find construction dust from old renovations, fine gray smoke particulate from fire seasons, and oak pollen packed into return-air ducts. We document what we removed and leave your home cleaner than we found it. Air Duct Cleaning in Cupertino.

Dryer Vent Cleaning in Cupertino
Dryer vents in Cupertino’s older ranch homes are often longer than they should be, running from a laundry room on one side of the house through a cramped crawl space to an exterior wall. The lint trap catches most of it, but what bypasses the trap packs into bends and joints over time. In foothill-adjacent neighborhoods, that lint mixes with dust and sometimes even ash that finds its way into the vent path. We open the full run and restore proper airflow.

What Cupertino Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"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."
