Air Duct Cleaning Company in Temple City - One Price Per System, Agreed Before We Start

Air Duct Cleaning Company in Temple City, CA

Air duct repair in Temple City usually costs between $450 and $1,200 depending on how much of the original ductwork needs attention, and most jobs take one day once we’re on site. Temple City’s mid-century housing stock creates a specific set of problems: galvanized ducts from the 1950s and 60s that were undersized when they were installed, wrapped in insulation that’s now crumbling, and often routed through attics too shallow for a person to stand in. Cobalt Air Duct Cleaning has served Temple City since 2016, and we’d rather show you what’s actually inside your ducts than guess at it. Call (866) 596-7835 when you’re ready to look.

Why Temple City Homes Are Different

Temple City is a small, densely built San Gabriel Valley suburb dominated by mid-century single-story tract homes. Much of the housing stock went up between the late 1940s and the 1970s, before central HVAC was standard in every build. That means the ductwork in many Temple City homes wasn’t part of the original construction: it was retrofitted later, often squeezed into low-pitch attics and cramped wall cavities that were never designed to hold a modern air system. We regularly find original 1950s through 1970s galvanized rectangular ducting, undersized for the airflow demands of a modern furnace or AC unit, wrapped in insulation that has disintegrated into dust.

The San Gabriel Valley climate makes it worse. Hot, dry summers with Santa Ana wind events push fine dust and ash into return-air systems. Wildfire smoke from the foothills settles into duct interiors. Smog and soot accumulate faster here than in a coastal city. When that particulate mixes with failing insulation fibers inside old duct runs, the air moving through the system carries it into every room. Temple City sits directly under the flight path of that smog and ash burden, and we see the result in the 1960s-era tracts: dusty supply vents, uneven cooling, and homes where the filter stays clean but the air doesn’t feel clean.

What we’re describing isn’t a cleaning problem. It’s a structural one. Clean air starts with a clean system, not just a clean filter, but in Temple City, the system often needs repair before it can be cleaned properly.

Our Main Temple City Services

Most Temple City homeowners call us for one of two reasons: the air coming out of their vents smells stale or dusty, or their dryer takes longer than it should to finish a load. Both services have their own dedicated pages, and both are jobs we handle with the same specialist focus.

Air Duct Cleaning in Temple City

Duct cleaning in Temple City means dealing with decades of accumulated dust, ash, and failing insulation in systems that were retrofitted into homes that predate central air. We run professional-grade Rotobrush and Nikro equipment through every supply and return run, agitating what’s bonded to the duct walls and pulling it into a HEPA-filtered vacuum. In Temple City specifically, we pay close attention to attic runs where daytime heat has baked dust into a hardened layer. For a full breakdown of what the cleaning process involves and what it costs, see our dedicated page: Air Duct Cleaning in Temple City.

Dryer Vent Cleaning in Temple City

Dryer vents in Temple City’s older homes are often routed through attics or under slab foundations, which means longer runs with more bends than you’d find in newer construction. Lint builds up at every turn, and in attic runs, heat from the roof makes that lint dry and brittle. Your dryer vent is a fire risk. We treat it like one. We clean the full run from the dryer to the exterior termination point, not just the first few feet. For specifics on how we handle Temple City’s vent configurations, see Dryer Vent Cleaning in Temple City.

Air Duct Repair in Temple City

Air duct repair in Temple City is about fixing what decades of heat, age, and poor original installation have done to the duct system. Homes in the 91780 ZIP code frequently have galvanized duct runs that weren’t sized correctly when central air was retrofitted in, and after forty or fifty years of San Gabriel Valley heat, the connections loosen, the insulation fails, and the ducts leak conditioned air into the attic. We repair what others overlook. Cobalt’s repair capability means we can identify and fix the root cause of contamination, not just clean around it. Our dedicated service hub covers the full scope: Air Duct Repair.

Ductwork Repair

Signs you need it

Rooms that never reach the temperature you set on the thermostat, visible dust around supply vents even after cleaning, and a musty smell that only appears when the AC kicks on.

What it costs in Temple City

Standalone ductwork repair in Temple City typically runs $150 to $450 per repair point, depending on whether we’re resealing a joint, patching a run, or rehanging a section that’s sagged.

How we do it

We inspect the full run with a camera to find every failed connection, then mechanically clean the area, reseal joints with mastic or aluminum tape, and re-insulate where the original wrap has failed.

Air Duct Replacement

Signs you need it

Ducts that have collapsed under their own weight, rust perforations in galvanized runs, or flex duct that has torn and is pulling attic air into the system.

What it costs in Temple City

Whole-home air duct replacement in Temple City generally falls between $2,500 and $7,500 for a single-story ranch, with partial replacements running $800 to $2,000 depending on how many runs are failing.

How we do it

We remove the failed sections, reuse what’s structurally sound, and install correctly sized replacement runs matched to your system’s airflow requirements, not just whatever was there before.

HVAC Duct Installation

Signs you need it

Homes in Temple City that still rely on wall furnaces or have central air retrofitted into systems that were never designed for it, leaving rooms with no supply air at all.

What it costs in Temple City

New HVAC duct installation for a Temple City home typically runs $3,000 to $8,000 depending on the number of rooms, attic access, and whether we’re replacing or installing from scratch.

How we do it

We calculate the airflow requirement for each room, design the duct layout for your home’s actual floor plan, and install sealed, insulated runs sized properly for your equipment.

Duct Replacement

Signs you need it

Original 1950s through 1970s galvanized ductwork with failing insulation, rust at the seams, or airflow that can’t be fixed by sealing alone.

What it costs in Temple City

Replacing original ductwork in Temple City’s older tract homes typically costs $2,500 to $6,500, with the final number driven by attic accessibility and how much of the system is beyond repair.

How we do it

We remove the old runs, inspect the plenum and boots for compatibility, and install new insulated ductwork sized correctly for the airflow your system actually needs.

What Air Duct Repair Costs in Temple City

How do I know my ducts need repair and not just cleaning?

If dust returns within weeks of a cleaning, if some rooms stay hot while others cool, or if you can feel air escaping around duct boots, the problem is structural. Cleaning won’t fix a leak. Call (866) 596-7835 and we’ll inspect before recommending anything.

Can you repair ducts in a low-pitch Temple City attic?

Yes, and we do it regularly. Temple City’s shallow attic spaces are a known challenge, which is why we carry camera inspection equipment and work in sections. We’ll tell you upfront what’s accessible and what the options are. Call (866) 596-7835 for a straight answer on your attic.
