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.

AfterFast, Reliable Air Duct Cleaning Across Fremont
Air duct cleaning in Fremont typically runs $350 – $650 for a whole-home residential system, with most jobs completed in a single visit. Our crews dispatch from the San Francisco Bay Area office and cover Fremont neighborhoods from Centerville to Warm Springs, usually booking within a few days of your call.
We’ve been working in Fremont long enough to know the local housing stock inside and out. The mid-century tracts in Irvington and Glenmoor carry different duct problems than the new townhomes going up near Warm Springs. That matters because a crew that treats every job the same will miss what’s actually wrong with your system. When you call (361) 326-5060, you’ll speak to a live person who knows the difference and can schedule you accordingly.
Why Hollis Air Duct Cleaning Is Fremont’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning has built its reputation in Fremont on The Garrison Standard: written prices before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise that puts the guarantee in writing on every job. Roy Castellanos leads our operation, and that standard applies to every Fremont home we enter.
Our technicians know Fremont’s specific challenges. They’ve cleaned ducts in 1960s ranch homes off Mowry Avenue where galvanized steel ducting has corroded at the seams, and they’ve pulled construction debris from brand-new condos in the Bayside district where the builder never sealed the registers. That local knowledge means we don’t waste your time guessing.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. When you’re ready to schedule, someone picks up.
Air Duct Inspection in Fremont
Air Duct Inspection in Fremont is where we start every job, because Fremont homes present problems you can’t diagnose from the vent cover. Our technician runs a video camera through your supply and return lines, documents what we find, and shows you the footage before we quote any work. A typical inspection runs $150 – $250, and if you proceed with cleaning, we apply that toward the job.
What We Look For in Newer Construction
In Warm Springs and Bayside townhomes, we’re hunting for drywall dust packed around elbows and shared-wall penetrations. Builders often skip register sealing during construction, and that debris doesn’t show itself until the first hot day kicks the blower to high speed. The camera finds it before your furniture does.
What We Find in Older Fremont Homes
In Irvington, Centerville, and the historic Niles district, we’re checking for undersized returns and leaky joints behind original plaster. These homes were retrofitted for central air decades after they were built, and the ductwork was never designed for modern airflow demands. Cleaning without finding those leaks first is half a job.
Residential Air Duct Cleaning in Fremont
Residential Air Duct Cleaning in Fremont covers the full system: supply ducts, return ducts, the main trunk lines, and the registers and grilles. We use a Rotobrush rotary brush system to agitate debris off duct walls, coupled with Nikro negative-air machines that pull the loosened material through HEPA filtration so it doesn’t resettle in your home. A typical single-family home in Fremont runs $350 – $550; larger homes or systems with multiple zones run $500 – $650.
The New-Build Problem No One Talks About
Here’s what most Fremont buyers don’t realize: your brand-new townhome may need duct cleaning before you unpack a single box. We were called to a just-completed townhome in the Warm Springs district where the homeowner noticed drywall dust puffing from every register on the first hot afternoon. Our tech ran a camera inspection and found the short, elbow-heavy supply and return ducts packed with construction debris and drywall dust that the builder had never sealed off during construction. Using negative pressure and Rotobrush agitation tools, we pulled the debris out through HEPA filtration, restored airflow, and the dust stopped recirculating into the living space.
Why Older Tracts Need a Different Approach
Homes in Irvington and Centerville often have flexible ducting from the 1980s or galvanized steel from the original build. The rotary brush adapts to each material, but the real work is often in sealing and balancing airflow after the cleaning. We use mastic sealant on accessible joints and note where your system needs an HVAC contractor to address structural limitations.
Trusted Brands We Service in Fremont
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use in hospitals and schools, not hardware-store vacuums with a longer hose. For Fremont homeowners, that means the job gets done to NADCA standards, with HEPA filtration that captures particles down to 0.3 microns. We stock common filtration accessories locally, so if your system needs a new media filter or upgraded return grille after cleaning, we can often handle it on the same visit rather than ordering parts and making you wait.
Common Air Duct Cleaning Problems We See in Fremont Homes
- Construction debris in new infill homes. Warm Springs and Bayside townhomes frequently have drywall dust and wood particles left in ductwork because builders skipped register sealing. A standard surface cleaning won’t remove it; source removal with agitation tools is required.
- Restricted airflow in elbow-heavy new construction. Short duct runs with multiple bends trap debris at joints and shared-wall penetrations where a straight vacuum hose can’t reach. We see this in nearly every new condo complex south of Auto Mall Parkway.
- Undersized returns in retrofitted older homes. Irvington and Centerville tract homes that added central air in the 1970s or 80s often have return ducts too small for modern blower capacity. Cleaning helps, but sealing and airflow balancing are usually needed to stop the system from working itself to death.
- Seasonal pollen and dust loading. Fremont’s dry summers pull hillside pollen and bayland dust into outdoor intakes, while winter moisture from the nearby bay can promote mold growth in poorly maintained systems. The combination means ducts here work harder than in drier inland climates.
Pricing for Air Duct Cleaning in Fremont, CA
Whole-home residential duct cleaning in Fremont typically runs $350 – $550 for a single-system home up to about 2,500 square feet. Larger homes, multi-zone systems, or homes requiring extensive construction-debris removal (common in new Warm Springs and Bayside builds) run $500 – $650. Commercial systems are priced by the linear foot of ductwork and number of air handlers; most Fremont retail or office jobs fall between $800 and $2,500.
What moves the price: square footage, number of supply and return vents, accessibility of the main trunk lines, and whether we find construction debris that requires extra agitation and HEPA filtration time. We write the price down before any work starts. That number does not move at the door. No per-vent add-ons, no “discovered problems” once we’re inside. You’ll know exactly what you’re paying, and you’ll have it in writing.

FAQs About Air Duct Cleaning in Fremont
Yes, and more often than you’d expect. Because Fremont’s rapid infill development in Warm Springs and the Bayside districts often leaves new townhomes and condos with short, elbow-heavy duct runs that were never sealed during construction, many brand-new homes here need a NADCA-standard cleaning before the first occupant ever moves in. The drywall dust and construction debris recirculates into your living space the moment the blower kicks on. Call (361) 326-5060 and we’ll inspect before you unpack.
Condos in Warm Springs and Bayside have compact, multi-elbow duct runs with shared-wall penetrations that trap debris where a straight vacuum can’t reach; we use Rotobrush agitation and camera guidance to navigate them. Older Irvington homes have straighter runs but often feature retrofitted central air with undersized returns and leaky joints behind plaster walls, so we seal and balance airflow after cleaning. The equipment changes, and so does our approach. Call (361) 326-5060 and we’ll match the method to your home.
Fremont’s rain-shadowed valley climate means warm, dry summers that keep dust airborne and recirculating, plus mild, wet winters that can introduce moisture and mold if your system pulls bay air through poorly sealed returns. Most Fremont homeowners benefit from cleaning every 3 – 5 years, but new construction with debris loads or homes with allergy-sensitive residents may need it sooner. Call (361) 326-5060 and we’ll assess your specific conditions.
Yes, and we do it regularly in Centerville and Glenmoor homes built in the 1950s and 60s. Galvanized steel can corrode at seams and joints over decades, so we inspect first with a camera to identify where the metal has degraded. The rotary brush system works on steel, but we adjust RPM and brush stiffness to avoid damaging thin or rusted sections. Call (361) 326-5060 and we’ll evaluate your system’s condition before quoting.
The builder should have sealed every register and return grille with plastic or foam covers before drywall installation, then performed a rough clean and final pressure test before certificate of occupancy. In practice, many Fremont infill builders skip these steps to save time and cost. The result is drywall dust, wood particles, and insulation scraps packed into ducts that were supposed to be clean. We document what we find with video, and some homeowners have successfully used that documentation to pursue builder remediation. Call (361) 326-5060 for an inspection and written report.
