Air Duct Cleaning Company in Pasadena, CA

Air duct repair in Pasadena is often a matter of working with what a 1920s Craftsman or 1940s ranch was built around, not what a modern HVAC contractor would install today. The homes north of the 210 and through Bungalow Heaven carry decades of retrofits: original gravity-furnace sheet metal spliced into flex runs, returns cut into hallway floors, and transitions that were never sealed properly. We clean the system, then we repair what’s letting new dust and ash back in. That’s the difference between a one-pass cleaning and a duct system that stays clean.

Why Pasadena Homes Are Different

Pasadena’s housing stock skews older than almost anywhere else in the San Gabriel Valley, and that age shows up inside the ductwork. Between 1900 and 1940, builders ran gravity furnaces through oversized sheet-metal plenums that relied on warm air rising, not blowers. When central AC arrived decades later, contractors connected modern coils and air handlers to those same original runs. The result is a patchwork: 80-year-old metal under the house meeting flexible duct in the attic, joined with improvised transitions and old cloth tape. In the bungalow neighborhoods of 91104 and 91103, we regularly open returns and find original 1920s plenums still connected to a modern AC coil, carrying decades of fine dust, plaster debris, and the occasional rodent nest.

The climate compounds the problem. Pasadena summers routinely push past 100°F, and Santa Ana wind events pull fine grit and wildfire ash out of the San Gabriel foothills and Eaton Canyon area. That dust settles into duct runs that were never designed to be sealed against it. Because attics and crawlspaces in these older homes are typically uninsulated and tight, ducts run through extreme heat and occasional winter moisture. Under pier-and-beam floors, winter rains can introduce damp air into return paths, creating conditions where dust turns to caked debris. And in historic districts like Bungalow Heaven and the Civic Center area, preservation rules often make full duct replacement impractical, so cleaning and targeted repair are the realistic path.

Our Main Pasadena Services

Most Pasadena homeowners call us for one of two reasons: an AC system blowing dust and running nonstop through summer, or a dryer that takes two cycles to finish a load. Both point to the same underlying issue: ductwork that hasn’t been touched since the house was retrofitted for central air.

Air Duct Cleaning in Pasadena

Air duct cleaning in Pasadena has to account for what’s actually inside these systems: plaster dust from original lathe-and-plaster walls, sand from old crawlspaces, and wildfire ash that’s accumulated over decades of Santa Ana seasons. We run Rotobrush and Nikro equipment through the full system, including the returns, supply runs, and the main trunk lines, not just the vent openings visible in each room. The job typically takes a half day in a standard two-bedroom bungalow, longer in larger post-war ranches with extensive attic runs. We capture what we remove, show you before-and-after images, and flag any leaks or failed connections we find along the way.

Dryer Vent Cleaning in Pasadena

Dryer vents in Pasadena’s older homes tend to be long, multi-elbow runs that snake through crawlspaces or out through old wall penetrations, often accumulating lint for years without anyone noticing. Add the dry air and high summer heat, and you have a genuine fire hazard. We clean the full vent path from the dryer connection to the exterior termination, confirm airflow with a measurable pressure check, and remove any bird or rodent nesting we find at the outlet. The job usually takes under two hours unless the vent run is unusually long or blocked. See Dryer Vent Cleaning in Pasadena for pricing and warning signs that a vent is past due.

Air Duct Repair in Pasadena

Air duct repair in Pasadena solves the problem that cleaning alone can’t: a sealed, intact duct system. The patchwork nature of older retrofits here means leaks, disconnected runs, and crushed flex sections are the norm, not the exception. When hot attic air gets pulled into the return side, your AC works harder and your indoor air gets dirtier. When a supply run has separated under the house, you’re paying to cool the crawlspace. Our repair scope covers identifying the full path of the system, sealing and reconnecting what’s salvageable, and replacing what isn’t. We offer Air Duct Repair as a standalone service because a clean system with leaks is still a failing system.

HVAC Duct Installation

Signs you need it

You’ve added a new furnace or heat pump but the existing ductwork is original to a 1920s or 1950s house and was never sized or sealed for modern airflow.

What it costs in Pasadena

New HVAC duct installation in Pasadena typically runs from $1,800 to $4,400 depending on the number of runs, access difficulty, and whether the attic or crawlspace needs prep work first.

How we do it

We calculate the required airflow per room, remove and dispose of the old runs, install new insulated flex or metal duct as the layout demands, seal transitions with mastic, and balance the system before we leave.

Ductwork Repair

Signs you need it

You can see disconnected or sagging duct runs in the attic, feel weak airflow from specific vents, or notice dust streaks forming around return grilles.

What it costs in Pasadena

Ductwork repair in Pasadena typically falls between $450 and $1,100, with the final figure depending on how many seams, transitions, or failed connections need to be addressed.

How we do it

We trace the full duct path, identify every separation and leak point, reseal or reconnect the affected sections, reinforce weak transitions with proper fasteners and mastic, and retest the system under pressure.

Duct Replacement

Signs you need it

You have collapsed or torn flex, rusted-through sheet metal in the crawlspace, or sections so packed with old debris and deteriorated lining that cleaning is no longer a viable option.

What it costs in Pasadena

Duct replacement in Pasadena generally ranges from $1,700 to $4,400, shaped by home size, whether the attic or under-house space is accessible, and how much of the old system must be removed.

How we do it

We map out the replacement scope, remove the failed sections, install correctly sized new ductwork with proper support and sealing, and verify the system delivers and returns air evenly across the house.

What Air Duct Repair Costs in Pasadena

What pushes a Pasadena repair higher is access: cramped crawlspaces under pier-and-beam floors, or attics with low clearance and original framing. We give you a single flat price for the agreed repair scope before work starts.

Can you repair ducts without replacing the whole system in Pasadena?

Yes. We reseal seams, reconnect separated runs, and replace only failed sections when the rest of the system is sound. That’s the most common repair we do in Pasadena’s older homes.

How long does duct repair take in Pasadena?

Most repairs are done in a single day. Larger replacements or installations across a full bungalow or ranch may run two to three days depending on attic and crawlspace access.
