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 in Fremont typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and our Fremont crews handle the specific problems this city’s housing stock and climate create: Bay Mud terrain, mid-century ductwork retrofitted decades after construction, and new infill builds with construction debris still in the lines.

Why Fremont Homes Are Different
Fremont sits on deep alluvial layers of Bay Mud and old creek-bed silt, and that geology shapes what we find in ducts here. The housing stock is split between two distinct eras: 1950s – 70s tract homes in Irvington, Centerville, and Glenmoor, and high-density townhomes and condos built during the tech boom in Warm Springs and Bayside. The older homes often have galvanized steel or early flexible ducting that was retrofitted for central air long after the walls went up, with undersized returns and leaky joints hidden behind original plaster. In the newer units, short duct runs with multiple elbows and shared-wall penetrations trap construction debris and drywall dust that the original builders never cleared.
The climate adds its own layer. Fremont’s rain-shadowed valley brings warm, dry summers that keep dust airborne and recirculating, while winter moisture off the bay creates conditions for mold and mildew inside poorly maintained ducts. The surrounding hills and baylands produce seasonal pollen loads that standard fiberglass filters simply don’t catch. We’ve cleaned systems in the historic Niles district where the ductwork was clearly sized for a drier, less allergen-heavy climate than what the Bay Area delivers now.
Our Main Fremont Services
Most calls we get from Fremont homeowners fall into three categories. Each has its own page with full detail on pricing, process, and what to expect.
Air Duct Cleaning in Fremont
Our Air Duct Cleaning in Fremont covers the full supply and return network with a Rotobrush rotary brush system and Nikro negative-air machine to pull dislodged debris out of your home entirely. In Fremont’s older tracts, we’re often working around ductwork that was never designed for modern HVAC loads, so we check airflow balance as we go. Newer infill builds in Warm Springs frequently need extra attention to construction dust trapped in elbows and shared-wall runs.

Dryer Vent Cleaning in Fremont
Our Dryer Vent Cleaning in Fremont removes lint buildup that restricts airflow and creates fire risk, especially critical in Fremont’s dense townhome developments where vents often run long distances with multiple turns. We clean the full run from appliance to exterior termination and verify airflow with a meter before we leave. The dry summer air here makes lint particularly prone to accumulating in rigid stretches.

Duct Sealing in Fremont
Our Duct Sealing in Fremont addresses the leaky joints and disconnected runs we find constantly in retrofitted mid-century homes, particularly around Irvington and Centerville where central air was added to systems never designed for it. We use mastic and mechanical sealing to close gaps that bleed conditioned air into attics and crawlspaces. In many Fremont homes, sealing delivers more comfort improvement than cleaning alone.

What pushes Fremont prices toward the higher end: multiple HVAC zones, ductwork in cramped crawlspaces common to Bay Mud construction, and the extra labor of working around retrofitted systems with limited access. What keeps them predictable: we write the price before touching anything, and that number does not move at the door.
