Air Duct Cleaning Company in West Whittier-Los Nietos, CA
Air duct repair in West Whittier-Los Nietos starts with a straightforward diagnosis: most of these 1950s and 60s stucco homes still run on the original sheet-metal ductwork, and after sixty-plus years of thermal cycling, it leaks. We’re Cobalt Air Duct Cleaning, and we’ve served West Whittier-Los Nietos since 2016. Our focus is the full duct system, not just the cleaning. When a duct run sags in a 140-degree attic or a return pulls dust from an unsealed chase, the fix is structural. That repair capability is what separates a real solution from a repeat cleaning bill. Call (866) 596-7835 for an honest assessment.
Why West Whittier-Los Nietos Homes Are Different
West Whittier-Los Nietos sits in a bowl. The Puente Hills rise to the north, the 605 and 5 freeways wrap the community, and temperature inversions hold the particulate in place. What that means for ductwork is simple: the air your system pulls in already carries diesel soot and brake dust from the freeways, plus pollen and fine soil from the semi-arid basin. Once that mix enters a leaky return duct, it gets distributed through every room, every day, all year. The homes themselves make it worse. Original sheet-metal ducts in these 1950s ranch houses were undersized when they were installed, and sixty years of room additions and garage conversions have pushed those same ducts past their intended load. We regularly find return air being pulled through wall cavities and attic spaces, not through sealed duct runs. In this ZIP code, 90606, ductwork is not a maintenance afterthought. It’s the difference between breathing what’s outside and filtering it.

Our Main West Whittier-Los Nietos Services
Most West Whittier-Los Nietos homeowners call us for one of two things: the duct cleaning they know they need, or the dryer vent cleaning they didn’t realize was a fire risk. Both are core to what we do, and both are treated as dedicated jobs with dedicated equipment, not add-ons.
Air Duct Cleaning in West Whittier-Los Nietos
This is the service most people expect: a full mechanical cleaning of the supply and return ducts, registers, and plenums. In West Whittier-Los Nietos, the decade of dust is compounded by the freeway particulate that settles into every low return. We run Rotobrush mechanical agitation with commercial HEPA-filtered vacuum capture, and we photograph the interior before and after so you can see what moved. For the full breakdown of what our cleaning includes and what it costs here, see Air Duct Cleaning in West Whittier-Los Nietos.
Dryer Vent Cleaning in West Whittier-Los Nietos
Lint is a fire load, and in these older homes the dryer vent often runs a long horizontal path through a crawlspace or attic before it exits. Every foot of that run is a place lint can accumulate. We treat dryer vent cleaning as a dedicated safety service with its own pricing and its own checklist, never a bundle item at the end of a duct job. The heat of a West Whittier-Los Nietos summer makes a restricted vent run hotter, and the risk climbs. Read the specifics on Dryer Vent Cleaning in West Whittier-Los Nietos.
Air Duct Repair in West Whittier-Los Nietos
Air duct repair in West Whittier-Los Nietos typically costs between $300 and $2,800 depending on whether we’re sealing a few loose joints or replacing a failed duct run. The local housing stock makes repair work particularly common: original sheet-metal ducts from the 1950s and 60s have seams that have simply let go, and attic temperatures that exceed 140 degrees in summer cause flex duct to sag, kink, or pull apart at the collar. We fix the structural problem first, then clean. For a full overview of our repair capability, see Air Duct Repair.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setting, dust filming on surfaces within days of cleaning, or a utility bill that climbs every summer are all signs that air is leaving the ducts before it reaches the room.
What it costs in West Whittier-Los Nietos
Ductwork repair in West Whittier-Los Nietos typically runs from $300 for sealing a few seams to $1,200 for repairing multiple failed joints and replacing damaged sections.
How we do it
We locate the leaks with a pressure test or visual inspection, then seal with mastic or aluminum tape, replace any crushed or disconnected sections, and re-insulate where the original wrap has failed.
Air Duct Replacement
Signs you need it
Ducts with rust-through, collapsed flex runs, or contamination that cleaning cannot remove, or original metal ducts so undersized that even a sealed system cannot balance the rooms, need replacement rather than repair.
What it costs in West Whittier-Los Nietos
Air duct replacement in West Whittier-Los Nietos typically costs between $1,800 and $2,800 for a main trunk and branch runs in a standard 1,200 to 1,600 square foot home.
How we do it
We size the new runs to the actual airflow the home now needs, replace the affected sections, seal every joint with mastic, and wrap the new duct in insulation rated for attic installation.
What Air Duct Repair Costs in West Whittier-Los Nietos
| Item | Typical range in West Whittier-Los Nietos |
|---|---|
| Ductwork repair (sealing, joint repair) | $300 – $1,200 |
| Air duct replacement (per main run) | $1,800 – $2,800 |
| HVAC duct installation (new system) | $2,500 – $5,500 |
Prices move higher when access is tight, when multiple runs are affected, or when the original installation left undersized ducts that need complete resizing. We quote one flat price for the repair before work starts, so the number you approve is the number on the invoice.
How do I know if my ducts need repair or just cleaning?
Cleaning removes what’s inside the ducts. Repair fixes the ducts themselves. If rooms are consistently uneven in temperature, if dust returns within days of cleaning, or if you can feel air moving in an attic or crawlspace, the ducts are leaking and cleaning alone won’t fix it.
Can you repair ducts without replacing the whole system?
Yes, in most West Whittier-Los Nietos homes we repair affected sections and seal the rest. Full replacement is only necessary when the metal is rusted through, flex runs have collapsed, or the original sizing cannot support the home’s current layout.

What West Whittier-Los Nietos Customers Say
"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Eric Chen"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."
- Justin Park"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
