Air Duct Cleaning Company in San Marino, CA
Air duct repair in San Marino is a different job than most of Los Angeles County. Homes here aren’t 1990s tract builds with uniform duct runs. They’re 1920s-to-1950s custom estates where central HVAC was added decades after the original construction, often squeezed into attics and crawlspaces never designed for it. The result is mismatched ductwork: patched junctions, undersized returns, and long, winding runs that leak conditioned air into unconditioned space. Our team handles that. We also provide full air duct cleaning and dryer vent cleaning for San Marino homeowners. Call (833) 620-4169 and we’ll tell you exactly what we’re looking at.
Why San Marino Homes Are Different
San Marino’s housing stock runs older and larger than almost anywhere else in the San Gabriel Valley. The dominant home style, Spanish Colonial and Mediterranean custom builds from the 1920s through 1960s, predates central air. When central HVAC arrived, ductwork was retrofitted into homes with original California basement and crawlspace construction. That means ducts often run through tight, irregular spaces, and joins between old and new sections are rarely clean.
The local climate compounds the issue. Inland San Gabriel Valley heat routinely pushes summer temperatures into the high 90s and low 100s, so San Marino AC systems run hard for four to five months straight. The air is dry and, in wildfire season, smoke-heavy. Return ducts and filters load quickly with fine particulate. Then fall brings the oak and deodar canopy over streets off Huntington Drive and Oak Knoll Avenue into play. Leaves, pollen, and wind-driven debris drop straight into outdoor condenser intakes and return-air grilles. San Marino duct calls spike after Santa Ana wind events and fire season, not in spring the way they do in coastal cities.
Homeowners in the 91108 ZIP code also tend to be exacting. Estate owners and property managers want documentation, before-and-after evidence of what was cleaned or repaired, and a level of discretion that fits a quiet residential community. We approach every San Marino job that way by default.

Our Main San Marino Services
San Marino homeowners most often call us first about two things: getting decades of dust and debris out of retrofitted duct runs, and clearing dryer vents that have never been properly maintained. Both get a dedicated San Marino page, linked below.
Air Duct Cleaning in San Marino
Air duct cleaning in San Marino is rarely a simple vacuum pass. Homes here have long duct runs, older grille designs, and years or decades of construction dust from remodels and rebuilds on large lots. Our process uses Rotobrush rotary brush systems to mechanically agitate debris inside duct walls, paired with Nikro HEPA negative-air vacuums that capture what’s dislodged instead of recirculating it into living spaces. We also inspect the full run, because retrofitted systems in older San Marino homes often hide disconnected sections or crushed flex lines. Learn more about Air Duct Cleaning in San Marino.
Dryer Vent Cleaning in San Marino
Dryer vents in San Marino’s older homes are frequently long, poorly routed, or made of outdated materials that trap lint. A clogged dryer vent is a leading household fire risk, and with laundry rooms often tucked into interior hallways of larger floor plans, the run to the exterior can stretch 15 feet or more. We clean dryer vents as a dedicated service using the same professional equipment we bring to air duct work, not as an afterthought. See Dryer Vent Cleaning in San Marino for the full breakdown.
Air Duct Repair in San Marino
Air duct repair in San Marino usually means correcting what decades of retrofit work left behind. Homes built in the 1920s through 1960s got central air added piecemeal, and we regularly find duct sections that were never properly sealed, connected, or sized for the system they feed. In summer, that means cooled air bleeding into attics and crawlspaces while upstairs rooms stay warm. In wildfire season, gaps in return ducts pull smoky outside air straight into the house. The problem isn’t the age of the home. It’s the ad hoc way ductwork was added to it. Our Air Duct Repair service addresses leaks, disconnections, crushed sections, and undersized runs so the system moves air the way it was supposed to.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setpoint, visible gaps or tape peeling at duct joints in the attic or crawlspace, and dust blowing from supply registers even after cleaning all point to duct leaks.
What it costs in San Marino
Ductwork repair in San Marino typically runs $250 – $650 per section depending on access in older retrofitted attics and crawlspaces, which is the most common scope we quote.
How we do it
We locate the failed section by inspection and pressure testing, then reseal or replace the damaged portion with mastic-sealed metal or flex duct that matches the existing system.
Duct Replacement
Signs you need it
Duct runs that are crushed, rusted through, lined with decades of debris that won’t release, or so undersized the system can’t breathe are replacement candidates, not repair candidates.
What it costs in San Marino
Duct replacement in San Marino generally runs $1,800 – $3,900 for partial systems and $4,000 – $10,000 for full-system replacement, with the higher end reflecting the long runs and difficult access common in older estate homes.
How we do it
We remove the failed sections, size the new runs to the blower and room load, install sealed metal or flex duct, and verify airflow at every supply register before we finish.
What Air Duct Repair Costs in San Marino
| Item | Typical range in San Marino |
|---|---|
| Ductwork repair (per section) | $250 – $650 |
| Partial duct replacement | $1,800 – $3,900 |
| Full-system duct replacement | $4,000 – $10,000 |
Access drives San Marino pricing more than any other factor. Retrofitted systems in 1920s – 1950s homes often route through tight attics and original California crawlspaces, and repair work that takes an hour in a newer house can take half a day when you’re working around old framing, finished ceilings, or estate landscaping.
Can you repair San Marino ductwork without opening walls?
Most of the time, yes. The duct runs in San Marino’s older homes are usually accessible through the attic or crawlspace, which means we can reach, seal, or replace sections without cutting drywall. When a duct is buried in a finished ceiling, we’ll tell you before we start and give you options. Call (833) 620-4169 for an exact quote based on your home’s layout.
How long does duct repair take in San Marino?
Section repairs typically take a half day to a full day. Partial or full duct replacement can run one to three days depending on access in older estate homes. We give you a clear schedule before work begins, and we don’t leave the job until airflow at every register checks out. Call (833) 620-4169 to get a specific timeline for your system.
Brands We Service in San Marino
We work on the brands San Marino homes actually have: Guardsman duct products, Honeywell air-quality and filtration controls, and Aprilaire whole-home systems.

What pushes San Marino pricing upward is access. Homes built before central air was standard have duct runs through attics, crawlspaces, and odd chases that newer builds don’t, and that adds labor hours. Every job gets one flat price per system agreed before work starts, so the invoice you’re quoted is the invoice you pay.

What San Marino Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Dale Pruitt"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Kurt Vaughn"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."
