Air Duct Cleaning Company in San Gabriel, CA
Air duct repair in San Gabriel usually means opening up a 60-year-old attic and finding duct runs that were installed when Eisenhower was president. The 1920s through 1960s ranch and Spanish-revival homes that dominate the 91775 and 91776 ZIP codes were built with galvanized sheet metal and early flex duct, and most of it has never been re-sealed or replaced. Cobalt Air Duct Cleaning has served San Gabriel since 2016, and the jobs here are rarely simple cleanings. They’re retrofits: sealing failed joints, replacing crushed runs, and correcting what decades of inland heat and Santa Ana dust have done to the system. Call us at (866) 596-7835 for an inspection that shows you what’s actually inside your ducts.
Why San Gabriel Homes Are Different
San Gabriel sits in the San Gabriel Valley, where summer temperatures regularly run 10 to 15 degrees hotter than coastal Los Angeles. That means central air conditioning cycles from May through October, and the duct system is moving air constantly for six months straight. The result is a fine dust load that accumulates faster here than in beach cities. Add Santa Ana wind events that push particulate through every gap in the building envelope, and you have systems that load up with pollen and silt at a rate most homeowners don’t expect.
The housing stock compounds the problem. Most San Gabriel homes are 1950s and 60s tract builds or earlier ranch styles, typically 1,200 to 1,800 square feet. They sit on raised foundations with low-pitch attics, and many still have their original galvanized duct runs. During the 1980s and 90s, energy-efficiency programs added blown-in insulation to these attics. That insulation is heavy. Over time, it crushes duct runs, disconnects joints, and leaves gaps that pull attic air, fiberglass particles, and dust directly into the living space. A camera inspection almost always finds a failed joint or a crushed run. That’s the difference between cleaning a duct and actually fixing the system.
These are not maintenance jobs. They’re repair jobs that start with a cleaning and end with the duct system operating closer to how it was designed, sealed, and, where necessary, replaced.

Our Main San Gabriel Services
San Gabriel homeowners reach out to us for two reasons more than any other: they want to know what’s inside their ducts, and they want the dryer vent handled before it becomes a fire hazard. Both jobs are more involved here than in newer construction, because the duct systems are older and the vents are often long, low, and packed with years of lint.
Air Duct Cleaning in San Gabriel
Air Duct Cleaning in San Gabriel starts with a camera inspection of the duct runs, because in a 1950s ranch home, the problem is rarely just dust. It’s a disconnected joint, a crushed flex run, or a return pulling from the attic. We use professional-grade Rotobrush and Nikro systems to agitate and extract what’s built up over decades. Then we show you the before-and-after images, so you’re not taking anyone’s word for it.
Dryer Vent Cleaning in San Gabriel
Dryer Vent Cleaning in San Gabriel addresses one of the leading causes of residential fires. Older San Gabriel homes often route dryer vents through low attics or under floors, where lint collects around bends and reductions. We treat this as a dedicated safety service: full-length mechanical cleaning, verification of airflow at the termination point, and a clear report on what was removed. Your dryer vent is a fire risk. We treat it like one.
Air Duct Repair in San Gabriel
Air duct repair in San Gabriel is a structural job, not a cosmetic one. The homes here were built with sheet-metal and early flex duct that has now been in service for 50 to 70 years. Inland heat bakes the attic, Santa Ana winds push dust through every gap, and blown-in insulation from the 80s and 90s has crushed runs and pulled joints apart. When a San Gabriel homeowner tells us their energy bills keep climbing and the house won’t hold temperature, we don’t start with a filter change. We start with a camera. What we find is almost always a failed connection, a crushed run, or a return pulling attic air. Cobalt Air Duct Cleaning handles Air Duct Repair as a standalone service, so we can fix the root cause rather than clean around it.
Ductwork Repair
Signs you need it
Rooms that never reach temperature, dust accumulating within days of cleaning, and a musty smell when the blower starts all point to ductwork that has separated or collapsed.
What it costs in San Gabriel
Ductwork repair in San Gabriel typically falls between $350 and $750 per section, depending on whether the run is accessible in the attic or buried under insulation and tight framing.
How we do it
We camera-inspect the entire run, cut out the failed section, fabricate a replacement to match the existing diameter, and seal the joints with mastic before re-testing airflow.
Air Duct Replacement
Signs you need it
When ducts are crushed flat, rusted through, or so brittle that joints fracture with a touch, replacement is the only repair that will last.
What it costs in San Gabriel
Air duct replacement in San Gabriel generally runs from $1,800 to $3,200 for a full system in a 1,200 to 1,800 square foot home, with partial replacements falling between $500 and $1,200.
How we do it
We remove the old duct material down to the plenum, measure and fabricate new R-6 or R-8 flex or galvanized runs, hang them with proper support, and seal every connection with mastic and UL-listed tape.
What Air Duct Repair Costs in San Gabriel
| Item | Typical range in San Gabriel |
|---|---|
| Ductwork repair (per section) | $350 – $750 |
| Air duct replacement (full system) | $1,800 – $3,200 |
| Partial duct replacement | $500 – $1,200 |
How long does air duct repair take in San Gabriel?
Most ductwork repairs in San Gabriel finish in one visit, usually three to six hours. A full replacement of an older ranch home’s system can take a full day, sometimes two if the attic access is tight and the runs are buried under blown-in insulation.
Will air duct repair actually lower my energy bills in San Gabriel?
Yes, when the failure is significant. A disconnected return pulling 140-degree attic air or a supply run blowing conditioned air into the attic forces the AC to run longer. Sealing those losses is measurable on the next bill. Call (866) 596-7835 for an exact quote. Estimates are free.

Most San Gabriel appointments are scheduled within two business days. We confirm a two-hour arrival window the day before and call when we’re en route. For property managers with multiple units, we can schedule several inspections in a single day.
No. Standard duct repair and replacement inside an existing home is treated as maintenance by the City of San Gabriel and doesn’t require a permit. If the job ever touches structural framing or gas lines, that changes, but typical duct work doesn’t enter that territory.
Yes. Most 1950s and 60s ranch homes in San Gabriel have scuttle-hole attic access and low-pitch rooflines. Our equipment and crews are set up for that reality. We’ve handled crawl-in attics throughout the 91775 and 91776 ZIP codes, and we always inspect the access before finalizing a quote.

What San Gabriel 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."
