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 Norwalk
Air duct cleaning in Norwalk typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We’re familiar with the post-war tract homes that define this city, and we know what hides inside those original galvanized steel ducts after 70 years of continuous use.
Hollis Air Duct Cleaning dispatches crews to Norwalk from our Los Angeles office, and we’ve built our schedule around the reality of working here: older homes with attics that hit 140°F, building code citations that don’t wait, and duct systems that need more than a vacuum run through them. Our phones are answered by a live person 24 hours a day, 7 days a week, so when a Norwalk homeowner calls after finding a citation notice on their door, someone picks up. Call us at (361) 326-5060.
Why Hollis Air Duct Cleaning Is Norwalk’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning team has worked enough Norwalk jobs to know the difference between a simple cleaning and a repair-and-seal project. The Garrison Standard means we arrive inside the quoted window, price the job in writing before we touch anything, and leave the site clean. Roy Castellanos leads this operation, and every technician who enters a Norwalk home is background-checked, uniformed, and accountable to The Garrison Code.
Our 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a slogan; it’s printed on every invoice. We don’t compete on teaser prices because we’ve seen what happens when crews rush through a Norwalk attic, miss the disconnected branch run, and leave the homeowner with the same citation six months later.
Air Duct Cleaning Services in Norwalk
Air Duct Cleaning Services in Norwalk start with understanding what kind of house we’re walking into. Most homes here are single-story, wood-framed tract houses from the 1950s and 1960s, typically 1,000 – 1,500 square feet with low-pitched roofs and original galvanized steel ductwork. That ductwork rusts from the inside out, accumulates decades of dust and debris, and often harbors rodent entry points that building code enforcement will flag. A standard residential cleaning runs $350 – $550; if we find crushed runs, disconnected branches, or failed mastic joints that need sealing, the total can reach $650 – $950.
Residential Duct Cleaning
Our residential work in Norwalk means pulling a Rotobrush rotary system through every reachable supply and return line, capturing dislodged debris with a Nikro negative-air machine and HEPA filtration. We camera-inspect before and after so you see what we see. In neighborhoods like Norwalk Park, we regularly find branch runs that have been disconnected for years, dumping conditioned air into attics that reach 140°F in summer.
Commercial Duct Cleaning
Commercial systems in Norwalk’s retail strips and small industrial buildings near the Santa Ana Freeway face a different load: heavier dust intake from freeway traffic, longer duct runs, and rooftop units that pressurize differently than residential split systems. We scale our equipment and crew size to the building, with the same written price guarantee.

HVAC Duct Cleaning in Norwalk
HVAC Duct Cleaning in Norwalk is not a maintenance luxury; for many homeowners, it’s a code-compliance necessity. Norwalk enforces visible duct debris and pest infestations under its building code, and we’ve taken calls from homeowners who received a citation notice before they ever noticed a comfort problem. The city’s warm, dry summers mean cooling systems run heavily from May through October, pulling in dust from nearby freeways and dry yards, accelerating contamination inside ducts that may have never been cleaned.
Full System Cleaning with Video Inspection
We run a camera through the full trunk and branch system before we quote. This matters in Norwalk because original galvanized steel trunks often show interior rust scale that light brushing won’t touch, and buried flex-duct retrofits may be crushed or disconnected. The video becomes your before-and-after record, and it’s how we catch the problems that other crews skip.
Supply and Return Duct Cleaning
Supply ducts push cooled air to your rooms; returns pull warm air back to the handler. In Norwalk’s 1950s homes, both run through uninsulated attics where duct tape and mastic fail in the heat. We clean both sides of the system, then test for leakage. If we find it, we quote sealing work in writing before we start.
Trusted Brands We Service in Norwalk
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for debris capture, and filtration products from Aprilaire, Abatement Technologies, and Guardsman. We don’t use hardware-store vacuums with a long hose. For Norwalk homeowners dealing with the aftermath of a code citation, this means we can source the right replacement components for original 1950s galvanized systems or modern flex-duct retrofits, and we carry mastic, foil tape, and mechanical fasteners rated for attic temperatures that regularly exceed 130°F. When a Norwalk Park homeowner needs a crushed branch run replaced and sealed, we have the materials on the truck.
Common Air Duct Cleaning Problems We See in Norwalk Homes
- Disconnected branch runs in 140°F attics. In Norwalk Park and surrounding older neighborhoods, we regularly find branch ducts that have separated from the main trunk, dumping cooled air into the attic and starving back bedrooms. The homeowner feels weak airflow; the code inspector sees dust accumulation at the register and issues a citation.
- Interior rust scale in galvanized steel trunks. Original 1950s ductwork rusts from the inside out. A light vacuum pass won’t remove adhered scale, and crews without agitation tools leave it to keep shedding into your supply air. We use Rotobrush mechanical agitation under negative pressure to dislodge it.
- Rodent entry through failed mastic and tape. Attic penetrations in Norwalk’s older homes open up as mastic dries and duct tape adhesive fails in summer heat. Cleaning removes the debris, but sealing the entry points is what keeps the citation from coming back next year.
- Crushed flex-duct retrofits from sloppy prior work. When previous owners or inexperienced contractors retrofitted flex duct over original galvanized, they often crushed it under insulation or compressed it at tight bends. We camera-locate these restrictions and quote repair before we clean.

FAQs About Air Duct Cleaning in Norwalk
Duct cleaning alone will not fix a code citation if the underlying problem is disconnected runs, rodent entry points, or rusted-through trunk lines. We camera-inspect first to determine whether cleaning plus sealing and repair is needed to pass re-inspection. Call (361) 326-5060 and we’ll walk through what your specific citation requires.
Norwalk Park attics are uninsulated and reach 140°F in summer, which destroys duct tape adhesive, cracks mastic, and causes metal expansion that loosens mechanical joints. That heat cycling is the root cause of most disconnections and rodent entry we find in this neighborhood. Sealing with high-temperature mastic and mechanical fasteners, not tape, is the fix that lasts.
Most original galvanized steel ducts in Norwalk can be cleaned and sealed rather than fully replaced, provided the trunk line hasn’t rusted through. We camera-inspect to assess wall thickness and joint integrity. Replacement becomes necessary when rust has perforated the metal or when multiple branch runs are crushed beyond repair.
A cleaning that requires reconnection of one or two branch runs, re-masting of joints, and sealing of rodent entry points typically totals $650 – $950 for a standard Norwalk tract home. We quote this range in writing after inspection and before any repair work begins. The original cleaning price does not balloon; the repair scope is priced separately and approved by you.
In Norwalk’s 1950s homes, back bedrooms are often fed by the longest branch runs, which are the most likely to have disconnected from the trunk or been crushed by insulation or storage items in the attic. We camera-locate these restrictions during our pre-cleaning inspection. Reconnection and sealing usually restores full airflow without any equipment upgrade.
We were called to a 1,100 sq ft 1950s tract house in Norwalk Park where the homeowner had a citation for rodent debris in the registers. Camera inspection showed the original galvanized trunk had rusted through at three joints and a branch run to the back bedroom was completely disconnected, dumping cooled air into a 140°F attic. We ran a Rotobrush with agitation tools under negative pressure and HEPA filtration, reconnected and sealed the crushed run with mastic, and the homeowner passed re-inspection – but the real fix was the sealing, not the cleaning.
