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.
Fast, Reliable Air Duct Cleaning Across East Foothills
Air duct cleaning in East Foothills typically runs $350 – $650 for a full residential system and is scheduled within a few days, not weeks. We dispatch crews from our San Francisco Bay Area office who know the foothill roads and the specific smoke-ash patterns that affect homes here.
We’ve worked the ranch homes along Mount Hamilton Road and the post-war slabs near East Capitol Expressway long enough to know what we’re pulling out of those ducts. After the SCU Lightning Complex fires, homeowners across East Foothills called us with filters that turned black inside of a month. That wasn’t ordinary dust. It was fine wildfire ash that had settled in galvanized trunk lines and overhead flex runs from the 1960s, then recirculated every time the furnace kicked on. Our crews use Nikro negative-air machines and Rotobrush rotary systems to extract that material, not just blow it around. If you’re seeing ash residue on vents or smelling smoke months after the last red-flag warning, your ductwork is likely holding more than you think.

Why Hollis Air Duct Cleaning Is East Foothills’s Preferred Air Duct Cleaning Company
We’ve built our reputation in East Foothills on showing up when we said we would and pricing the job in writing before we touch anything. That matters here because the foothill terrain and older housing stock mean every job has variables: slab foundations with limited access, original galvanized ducts that have never been opened, DIY add-ons that created dead zones where ash collects. Our Air Duct Cleaning team accounts for those conditions during the estimate, not after we’re inside.
Our technicians are background-checked, uniformed, and expected to operate under The Garrison Code: arrive inside the quoted window, explain the scope before starting, leave the site clean. East Foothills homeowners have told us the difference is having a crew that treats a 1950s ranch with the same discipline as a new build in the valley. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. And every job carries our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit.
Air Duct Repair in East Foothills
Air Duct Repair in East Foothills addresses the cracked seams, disconnected flex runs, and corroded galvanized sections common in the area’s mid-century housing stock. Much of East Foothills was built during the 1950s – 1970s boom, and original ductwork in those ranch homes has endured sixty-plus years of thermal cycling, rodent activity in the foothills, and now repeated smoke-ash exposure that accelerates metal fatigue. Repair becomes necessary when you’re losing conditioned air into attics or crawl spaces, when rooms never reach temperature, or when your energy bills spike without explanation. Typical repairs in East Foothills range from $200 for a section of reconnected flex duct to $800 – $1,400 for replacing corroged galvanized trunk lines in a slab home with limited access.
Smoke-Ash Damage to Metal Ducts
Fine particulate from Diablo Range wildfires settles in duct seams and accelerates corrosion in older galvanized steel. We inspect for pinhole leaks and separated joints that standard cleaning won’t fix, then repair with code-compliant materials.
Flex Duct Collapse in Overhead Runs
Long overhead spans in low-ceilinged East Foothills ranches often sag or crush where they were improperly supported during original installation or DIY modifications. We replace collapsed sections with properly routed, supported flex duct that restores airflow.
Ductwork Cleaning in East Foothills
Ductwork Cleaning in East Foothills means removing the accumulated ash, PM2.5, and debris that foothill conditions deposit in ways flatland homes don’t experience. The area’s winter temperature inversions trap wood-smoke and valley pollution against the hills; summer wildfire smoke infiltrates through every gap. By the time homeowners notice reduced airflow or a persistent burnt smell, the entire system from return plenum to supply registers needs attention. A full residential ductwork cleaning in East Foothills typically costs $350 – $650 depending on system size, access difficulty, and whether video inspection reveals blockages requiring additional work.
Negative-Air Method with Rotary Agitation
We connect a Nikro negative-air machine to your trunk line, creating suction that pulls loosened debris toward the collection unit while a Rotobrush rotary system scrubs the interior walls. This dual approach extracts fine ash that compressed-air “blow-and-go” methods leave behind.
Video Inspection Before and After
Our technicians feed a camera through the system to show you the condition before work starts and verify the results after. In East Foothills, these photos often reveal blackened returns after fire season that surprise homeowners who changed their filters regularly.
Trusted Brands We Service in East Foothills
We maintain equipment and filtration inventory from Honeywell, Aprilaire, and Abatement Technologies to match what we encounter in East Foothills homes. Many of the ranch houses in this area still run original Honeywell media filters or early Aprilaire whole-house units installed during the 1970s energy-efficiency push. We stock replacement media and upgrade components to avoid ordering delays that leave foothill residents without filtration during smoke season. Our Nikro negative-air collection systems and Rotobrush rotary cleaning equipment are the same units commercial crews use in hospitals and schools, not hardware-store extractors. When we recommend a filtration upgrade after cleaning, it’s with specific product knowledge of what works in older duct systems with lower static pressure tolerance.
Common Air Duct Cleaning Problems We See in East Foothills Homes
- Wildfire ash infiltration in original galvanized ducts. The SCU Lightning Complex and subsequent fire seasons deposited fine ash in ductwork throughout the Diablo Range foothills. East Foothills homes with unsealed return plenums or aging trunk lines pulled that material directly into living spaces, where it recirculated for months after visible smoke cleared.
- DIY duct modifications creating dead zones. Ranch home owners in the 1970s and 1980s often added flex duct runs themselves to condition converted garages or additions. Those long, unsupported spans now sag and collect debris in overhead cavities that standard cleaning heads can’t reach without disassembly.
- Winter inversion trapping wood-smoke and PM2.5. When cold air settles in the Santa Clara Valley and holds pollutants against the foothills, East Foothills homes with leaky duct envelopes pull contaminated outside air into the return side, loading filters and duct interiors faster than valley locations.
- Slab foundation limiting access to trunk lines. Many East Foothills ranches were built on slabs with centrally located furnaces and buried or surface-mounted trunk ducts. Cleaning these systems requires specialized access ports and negative-air containment that inexperienced crews skip or don’t own.
