Air Duct Cleaning Company in North Hollywood, CA
Air duct repair in North Hollywood usually means one of two things: sealing the gaps and separated joints that have opened up in original 1950s and 1960s sheet-metal ductwork, or replacing sections that have collapsed, corroded, or been crushed in the tight attic and crawl spaces common to San Fernando Valley ranch homes. Because so much of this neighborhood’s housing stock predates modern sealing standards, we spend as much time restoring compromised duct runs as we do cleaning them. If your system is leaking conditioned air into the attic or pulling dust from wall cavities, call (833) 589-9715.
Onyx Duct Cleaning has served North Hollywood since 2013, working on the mid-century homes and older apartment buildings that define the area. Our approach ties directly to what we find here: hard metal ducts with failing joints, sagging flex connectors, and decades of accumulated Valley dust that no consumer-grade vacuum can reach.
Why North Hollywood Homes Are Different
North Hollywood sits in the eastern San Fernando Valley, where hot, dry summers and seasonal Santa Ana winds push a steady load of fine dust and pollen into return-air systems. That particulate load settles in the ductwork, and in a 1950s ranch home, the ductwork itself is often part of the problem. Original rigid metal ducts from that era were assembled with basic slip joints and minimal sealing, and after 60 or 70 years, those joints separate. A disconnected return duct doesn’t just leak air; it actively pulls dust, insulation fibers, and whatever else is living in the attic or wall cavity directly into the conditioned air stream.
The blocks just north of the 101 freeway have their own pattern. Technicians working those streets routinely find original 1950s duct runs in ranch homes with sagging flex-duct connectors and disconnected joints hidden above drop ceilings, a problem that becomes apparent only after the first heavy fall Santa Ana wind event. The wind event doesn’t cause the separation; it exposes it, because the pressure changes make the leak audible or push dust through the registers in a way homeowners finally notice.
Multi-unit rental buildings from the 1960s through the 1980s present a different set of conditions. These stucco apartments often share common return-air pathways, which complicates cleaning access and means one unit’s dust problem can be fed by another unit’s neglected return. Winters here are mild, but dampness can collect in poorly ventilated older apartments, and that moisture combined with trapped dust creates conditions where mold grows quietly inside the ductwork. North Hollywood is a basin, and pollen and particulate levels spike seasonally, so the work here is as much about restoring system efficiency after decades of accumulated debris as it is about routine maintenance.

Our Main North Hollywood Services
The two calls we get most from North Hollywood homeowners are straightforward: clean the ducts, or clear the dryer vent. Both services address different parts of the same ventilation pathway, and both are jobs where the local housing age works against the homeowner.
Air Duct Cleaning in North Hollywood
Duct cleaning in North Hollywood involves a full contact cleaning of the supply and return sides of a forced-air system, including the main trunk line, branch runs, and accessible plenums. The older the home, the more we expect to find: compacted dust, construction debris from decades-old remodels, and sometimes the remains of a rodent or two. Our Air Duct Cleaning in North Hollywood page covers the full process, local pricing, and what to expect from a Rotobrush contact-cleaning system and Nikro HEPA vacuum setup.

Dryer Vent Cleaning in North Hollywood
Dryer vents in North Hollywood’s ranch homes often run long horizontal distances from the laundry room to an exterior wall, sometimes crossing a garage or crawl space. Lint accumulates at every bend and low point, and in a 1960s home, the vent may be the original thin-foil connector that should have been replaced years ago. Our Dryer Vent Cleaning in North Hollywood page explains how we clear those runs and why the fire risk is real.

Air Duct Repair in North Hollywood
Air duct repair in North Hollywood is the service that separates a thorough cleaning from a real fix. The basin’s airborne dust loads are high, but the larger issue in this housing stock is structural: original sheet-metal ductwork with separated joints, disconnected flex-duct connectors, and runs that were undersized even when they were installed. Cleaning those ducts without repairing the leaks would be like sealing a bathtub while the drain is still open. Onyx Duct Cleaning brings the same contractor-grade standard to Air Duct Repair that we bring to cleaning: we find the separation, seal it or replace the section, and verify the run holds pressure before we finish.
Ductwork Repair
Signs you need it
You’ll notice weak airflow from certain registers, a persistent dusty smell even after cleaning, or rooms that never reach the same temperature as the rest of the house.
What it costs in North Hollywood
Ductwork repair in North Hollywood typically runs $350 – $800 per section, depending on access and whether we’re sealing joints or replacing a collapsed segment.
How we do it
We locate the separation with visual inspection and pressure testing, then re-secure and seal the joint with mastic and metal tape, or cut out and replace the damaged section with correctly sized material.
Air Duct Replacement
Signs you need it
If the ductwork is crushed, corroded, or torn beyond repair, or if repeated patching hasn’t stopped the leaks, replacement is the only fix that restores system efficiency.
What it costs in North Hollywood
Air duct replacement in North Hollywood is priced per linear foot, typically $45 – $80 per foot for rigid metal duct and $25 – $45 per foot for flexible duct, labor included.
How we do it
We remove the failed section or entire run, install new duct with proper supports and sealing, and test the system for airflow and leaks before we put it back into service.
HVAC Duct Installation
Signs you need it
New additions, remodels, or HVAC upgrades often need new duct runs sized and installed to match the system’s air volume requirements.
What it costs in North Hollywood
HVAC duct installation in North Hollywood typically runs $2,500 – $6,000 for a partial system and $6,000 – $12,000 for a full single-family home, depending on the number of runs and access.
How we do it
We size each run to the room’s load calculation, route it through the available attic or crawl space, and seal every joint before connecting the run to the plenum.
What Air Duct Repair Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Ductwork repair (per section) | $350 – $800 |
| Air duct replacement (per linear foot, rigid) | $45 – $80 |
| HVAC duct installation (partial system) | $2,500 – $6,000 |
Can you repair disconnected ducts above a drop ceiling?
Yes. We access the space above the drop ceiling by removing the appropriate tiles or panel sections, reconnect the separated run, seal the joint, and replace the ceiling. Call (833) 589-9715 for an exact quote on your system.
Why is my older North Hollywood home’s airflow so weak even after cleaning?
In most cases we find the answer in separated duct joints or crushed flex connectors. The age of the original sheet-metal runs and the sag from decades of temperature cycling means leaks are common. We test for pressure loss and repair the failed sections.

What pushes a North Hollywood job toward the upper end is usually access. Tight crawl spaces, ducts run above drop ceilings, and multi-unit buildings with shared returns all add labor time. That’s why we give one flat price per system before work begins, based on a written estimate, not a per-vent figure that grows once the van is parked.

What North Hollywood Customers Say
"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
- Jodi Gallagher"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
- Bryce Norris"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
