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 Norwalk, CA
Air duct cleaning in Norwalk, CA typically runs $350 – $650 for a whole-home system, with most jobs completed in one visit. Hollis Air Duct Cleaning handles the specific challenges of Norwalk’s older housing stock: post-war tract homes with original galvanized steel ductwork, heavy summer cooling loads, and attic temperatures that degrade seals and invite pests. We’re part of the Garrison Partners family, and every job comes with a written price before we start and our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Norwalk Homes Are Different
Most Norwalk houses are single-story, wood-framed tract homes built in the 1950s and 1960s, running 1,000 – 1,500 square feet with low-pitched roofs. The original galvanized steel ductwork in these homes rusts, leaks, and accumulates decades of dust that newer flex-duct systems don’t trap in the same way. We’ve opened registers in Norwalk Park homes and found compacted debris from the Eisenhower era.
The climate here compounds the problem. From May through October, HVAC systems pull near-constant cooling loads, drawing in freeway dust from the 5 and 605 corridors plus fine particulate from dry, unlandscaped yards. Attic ducts in neighborhoods like Norwalk Park routinely hit 140°F in summer. That heat cooks duct tape and mastic seals, creating gaps that rodents exploit from nearby fields. Technicians on our crews see this pattern weekly.
Norwalk’s building code enforcement adds another dimension. The city cites homeowners for visible duct debris or pest infestations, especially during resale inspections or rental turnovers. This creates demand tied directly to compliance, not just comfort. Contractors in Cerritos or Downey don’t encounter the same pressure because their housing stocks and enforcement patterns differ.
Our Main Norwalk Services
These are the three services Norwalk homeowners call us about most often. Each has its own page with detailed pricing, process, and local specifics.
Air Duct Cleaning in Norwalk
We clean the full supply and return network with Rotobrush rotary brush systems and Nikro negative-air machines that pull dislodged debris out of your home rather than redistributing it. In Norwalk’s 1950s tract homes, we often find original ductwork with rust-scale buildup and previous owners’ remodeling debris. The job includes all registers, the main trunk, and the return plenum. Air Duct Cleaning in Norwalk covers full pricing and what to expect.

Dryer Vent Cleaning in Norwalk
Dryer vent blockages are a genuine fire hazard, especially in older Norwalk homes where vents may run through walls or under slab with limited access. We clear the full run from appliance to termination, verify airflow with a meter, and flag any code issues. Many Norwalk homeowners combine this with air duct cleaning for one coordinated visit. Dryer Vent Cleaning in Norwalk has the details.

Duct Sealing in Norwalk
After cleaning, we often find disconnected runs, rust holes, or failed seals in Norwalk’s original metal ductwork. We seal with mastic and mechanical fasteners rated for attic temperatures, not tape that will cook off again in six months. This restores system efficiency and blocks the entry points rodents use. Duct Sealing in Norwalk explains when sealing makes sense versus replacement.
