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 Sunnyvale, CA
Most Sunnyvale homes run between $450 and $900 for a full air duct cleaning, with ranch houses on the east side typically landing at the lower end and larger two-story homes in newer tracts running higher. What makes Sunnyvale jobs different from neighboring cities is the housing stock itself: thousands of single-story ranch homes built between 1952 and 1975 still carry original sheet-metal ductwork with fiberglass liner that has been degrading for half a century. If you suspect your ducts have never been cleaned, call us at (469) 972-3151 and we’ll give you a written price before any work begins.
Why Sunnyvale Homes Are Different
Sunnyvale’s residential neighborhoods east of El Camino Real and around Ponderosa Park are dense with 1950s-1970s ranch homes built quickly for Lockheed Missiles & Space and early Silicon Valley workers. Those houses share a common problem: original sheet-metal supply ducts insulated with fiberglass wrap that deteriorates over time and sheds particles into the airstream. When we open a register in a Ponderosa Park ranch, we usually find dust that has been accumulating since long before the current owner bought the house.
There’s also a second wave of 1980s-1990s tract homes with flex-duct systems, and Sunnyvale’s occasional extreme heat events have caused some of that flex duct to kink or partially collapse. Homeowners remodeling a 1960s ranch into an open-concept floor plan add another layer: construction drywall dust coats supply runs end to end, even in houses that look spotless above the ceiling. Sunnyvale sits at the bottom of the Santa Clara Valley basin, which traps wildfire smoke from the Diablo Range and Santa Cruz Mountains during fire season, pushing post-smoke duct cleaning demand here higher than in coastal cities.
Our Main Sunnyvale Services
Sunnyvale homeowners call us most often about two things: the ducts themselves and the dryer vent that hasn’t been cleared in years. Each service has its own Sunnyvale page with full pricing and details.
Air Duct Cleaning in Sunnyvale
Air duct cleaning in Sunnyvale means pulling decades of settled dust, pet dander, and degraded fiberglass liner out of supply and return runs. We run a Rotobrush rotary brush through the ducts to loosen debris at the wall, then a Nikro negative-pressure unit pulls it out while an Abatement Technologies HEPA filter keeps the particles out of your living space. The full breakdown, including pricing for older ranch homes and post-renovation cleanups, is on the dedicated Air Duct Cleaning in Sunnyvale page.

Dryer Vent Cleaning in Sunnyvale
Dryer vent cleaning in Sunnyvale deals with lint that packs into the vent run from the dryer to the outside wall. Ranch homes with short horizontal vent runs clog differently than two-story homes with long vertical runs, and both can hide lint behind the lint trap where a shop vac will never reach. We use a professional brush system and negative air to pull the lint out completely. Detailed scope and pricing are on the Dryer Vent Cleaning in Sunnyvale page.

What Sunnyvale 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."
