Air Duct Cleaning Company in Pasadena, CA
Air duct repair in Pasadena usually means contending with ductwork that has been in place since the Coolidge administration. The city’s concentration of pre-1940 Craftsman and Spanish Colonial Revival homes means original sheet-metal ducts, interior wall chases used as returns, and decades of wildfire ash packed into cavities that newer homes simply don’t have. Our work here is often less about cleaning and more about deciding what can be salvaged and what needs replacement. Call (833) 589-9715 for a free estimate.
Why Pasadena Homes Are Different
Pasadena’s housing stock spans three distinct eras, and each one presents its own ductwork profile. In Bungalow Heaven and other historic districts, homes from the 1900s through the 1930s often retain original gravity-furnace ductwork: unlined wall cavities carrying return air, sheet-metal runs that have oxidized for a century, and floor registers made of redwood or fir. These systems were never designed for modern filtration. They collect everything, and cleaning them properly requires hand work, not a quick negative-pressure pass.
East Pasadena’s post-war and 1960s – 70s ranch homes tell a different story. The flexible duct common in those builds sags, tears, and pulls apart at the joints after decades of attic heat. Duct leakage in those homes can exceed 30 percent, meaning conditioned air heads into the attic rather than the living room. Newer infill construction near Old Town tends toward modern sealed systems, but even those collect the same atmospheric load during Santa Ana season.
The climate compounds all of it. Summers routinely pass 100°F, so HVAC systems run for months without rest, pulling dust into returns continuously. The Santa Ana winds from the San Gabriel Mountains carry fine particulate and seasonal wildfire ash that settles into every duct interior. Mild winters mean only a brief heating shift, but the dust load is year-round. This is not a market where a superficial blowout does anything meaningful.

Our Main Pasadena Services
Most Pasadena homeowners call us for two things: cleaning the air pathway they breathe every day, and clearing the dryer vent that vents moist lint through their walls or attic. The two jobs share a root cause here: old houses with long continuous duct runs and vents that have never been properly serviced.
Air Duct Cleaning in Pasadena
Cleaning a Pasadena duct system means addressing what has accumulated over decades, not just seasons. In older homes around Bungalow Heaven, we routinely find wall-cavity returns caked with soot from retired gravity furnaces and ash from nearby foothill fires. Standard truck-mounted equipment cannot reach those cavities; hand-cleaning and HEPA vacuuming are the only approach that actually removes the material. For newer systems, our Rotobrush contact-cleaning removes debris at the duct wall, and our Nikro HEPA vacuums capture particulates down to 0.3 microns rather than recirculating them through the house. Air Duct Cleaning in Pasadena is a fuller discussion of the process.
Dryer Vent Cleaning in Pasadena
Long dryer vent runs through Pasadena attics and exterior walls accumulate lint at every bend, and lint is fuel. The hot, dry summers only increase the stakes. A vent that has not been cleaned in years is pushing heated air past a growing obstruction, and we treat that as exactly what it is: a fire hazard to be removed, not a chore to be delayed. Our process clears the full run from the dryer connection to the exterior termination and confirms airflow at the end. Dryer Vent Cleaning in Pasadena covers what to expect and why a full-length cleaning matters.
Air Duct Repair in Pasadena
Repairing ductwork in Pasadena often starts with a question: is the original material worth saving? In homes from the 1920s and 1930s, we find galvanized steel that is still sound but buried in wall chases that were never meant to be accessed. In others, decades of attic heat have separated joints, collapsed flexible runs, and turned what should be a closed system into a network of leaks. The fix is rarely one-size-fits-all; it depends on what the ducts are made of, where they run, and whether the problem is the duct itself or the connection points.
That is where Air Duct Repair separates us from a cleaning-only contractor. We can identify the actual failure and repair or replace it, rather than simply cleaning around a problem that will return within a season. A cleaned duct that still leaks into the attic is still a failed duct. In Pasadena’s older homes, leak rates matter enormously because the conditioned air has to travel further through hotter spaces to reach the rooms.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat temperature, unusual dust settling right after cleaning, or a sudden jump in the summer electric bill without a change in usage all point to duct leakage.
What it costs in Pasadena
Typical ductwork repair in Pasadena runs from $350 – $900 depending on the number of failed joints, access difficulty, and whether repairs happen in an attic, crawlspace, or finished wall cavity.
How we do it
We locate the failed sections with a visual inspection and pressure testing where needed, then seal joints with mastic and foil tape, re-support sagging runs, and confirm airflow at the affected registers.
Air Duct Replacement
Signs you need it
Flexible duct that has tears, collapsed sections, or visible mold growth, or sheet metal that has rusted through or separated beyond repair, should be replaced rather than patched.
What it costs in Pasadena
Air duct replacement in Pasadena typically ranges from $1,200 – $2,800, with larger homes and multi-story systems at the upper end of that range.
How we do it
We remove the failed duct, size the replacement to the existing system, install new sealed runs with proper hangers and insulation, and verify airflow at every register before we leave.
HVAC Duct Installation
Signs you need it
Homeowners adding a room, renovating a kitchen, or converting a garage into living space need new duct runs sized and routed to match the existing HVAC system’s capacity.
What it costs in Pasadena
New HVAC duct installation in Pasadena typically costs $3,500 – $6,800, depending on the number of runs, access from attic or crawlspace, and whether a new return is required.
How we do it
We measure the room load, size ducts to match the system’s static pressure, install sealed galvanized or flexible runs with proper insulation, and balance airflow to the new space.

Do I need a permit for duct repair in Pasadena?
In most cases, repairing or replacing existing ductwork does not require a permit, but adding new duct runs to a home in Pasadena may trigger one. Your written estimate will note any permit needs before work begins.
How long does duct replacement take in Pasadena?
Most duct replacement jobs in Pasadena finish in one day, particularly in single-story ranch homes where attic access is straightforward. Multi-story or historic homes with inaccessible wall chases may require a second day. Call (833) 589-9715 for an exact estimate.
Brands We Service in Pasadena

In Pasadena, the age of the home and access to the ductwork push pricing more than anything else. A 1925 Craftsman with wall-cavity returns takes longer and requires hand-cleaning, which is reflected in the estimate. Every price is set per job by a written estimate before we begin, so the number you approve is the number you pay.

Yes. Original wall-cavity returns are common in Pasadena’s pre-1940 homes, and they require hand-cleaning and HEPA vacuuming rather than a standard truck-mounted pass. We do not clean around the problem; we open the cavity and remove what is actually in there.
