Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Vent Cleaning in Los Angeles
Vent cleaning in Los Angeles usually means addressing supply registers, return grilles, and the duct runs that connect them, and in older LA homes that job is often more involved than a homeowner expects. Because much of Los Angeles housing stock is 1920s to 1950s bungalows and duplexes in the basin, many systems use old-style gravity floor furnaces or undersized plenum returns rather than modern central air handlers. That means duct runs are often short, oddly routed, and hard to access without cutting into walls or floors. We price vent cleaning as one flat rate per system, typically $250 to $450 for a smaller bungalow or duplex in neighborhoods like Highland Park or South LA, and $400 to $700 for a larger single-family home with multiple returns.
What We Actually Do During a Vent Cleaning
We connect a Nikro HEPA-rated vacuum to create negative pressure. That is trade talk for pulling air and loosened debris into the vacuum, not blowing it back into your living room. Then we run a Rotobrush agitation tool through each supply and return, dislodging the dust film, pet dander, and construction debris that settles in LA ductwork. The process finishes with a camera inspection so you can see the duct walls before and after on our tablet.
When a Los Angeles Home Needs It
If you have a floor furnace in a 1930s bungalow off York Boulevard, or a central system in a 1960s ranch in the Valley, the interval is different. A system with a single return and three supplies in a gravity-fed bungalow might only need attention every four to five years. A central system in a home near a busy corridor like Sunset Boulevard or Crenshaw collects more fine particulate from traffic and might warrant cleaning every two to three years. We will tell you honestly if your system does not need the full job, and we will show you the photos to back it up.
Air Duct Repair in Los Angeles
Air duct repair in Los Angeles covers a lot of ground because our housing stock is old and our ductwork is often patched, rerouted, or just plain failing. We repair rusted-out plenums on gravity floor furnaces, torn flex duct in attics, collapsed returns behind closet walls, and separated joints that leak conditioned air into crawlspaces. A typical air duct repair in Los Angeles runs $200 to $600 for a single localized fix like resealing a run or replacing a damaged section. More involved work, like rebuilding a plenum or rerouting a short gravity-furnace duct run, lands between $600 and $1,400. Every repair gets a written guarantee, and if the repair fails within the year, the second visit is free.
Plenum and Return Repairs
In a 1948 bungalow off York Boulevard in Highland Park, our tech found a floor furnace with a rusted-out plenum and a return duct routed through a closet wall. The blower motor was pulling attic dust straight into the living room. We set up negative pressure with HEPA filtration, ran agitation tools through the single return and three supply ducts, and finished with a camera inspection that showed the before and after on our tablet. The homeowner could see the difference on their own duct walls, not just our word.
Sealing and Reconnecting
Most LA duct leaks happen where the metal meets the boot or where flex duct attaches to a floor register. We reseal those joints with mastic and foil-backed tape, not duct tape that dries out in the heat of a South Bay attic. If a section of flex duct is crushed or torn, we replace it and confirm airflow on the camera before we leave.
Trusted Brands We Service in Los Angeles
We work on systems built around every major brand found in Los Angeles homes, including Carrier service in Los Angeles, and our technicians stock common replacement filters and components from Aprilaire, Guardsman, and Abatement Technologies to keep turnarounds fast for our local customers. Whether you have a gravity floor furnace from the postwar era or a modern central system with a whole-home filter, we carry the parts needed for routine service on our trucks. For less common components, our Los Angeles parts network gets what we need quickly, usually same week. You will always know if we are waiting on a part before any work begins.
Common Air Duct Cleaning Problems We See in Los Angeles Homes
- Gravity floor furnaces with no accessible trunk line. Many 1920s through 1950s bungalows in neighborhoods like Echo Park and West Adams use these, and they require cleaning from inside the home rather than from an attic or crawlspace. Our pricing accounts for that access before we start, so there is no surprise charge when the duct run turns out to be short and buried behind a wall.
- Rusted-out plenums on older systems. Floors settle and air handlers sit in damp crawlspaces, so the metal box connecting the furnace to the ducts corrodes over time. That corrosion sends flaked metal and rust particles into the air stream, and it is one of the most common things we patch or replace during a cleaning call.
- Torn flex duct in attics and crawlspaces. LA’s heat bakes attic spaces to 130 degrees or more in summer, which dries out and cracks older flex duct. A torn run pulls insulation and dust into the system and blows it into living spaces, which is why a camera inspection after cleaning matters so much.
- Systems pulling in wildfire smoke residue. When smoke settles over the basin from fires in the San Gabriels or Santa Monicas, it does not stay outside. It settles into return registers and coats duct interiors. A post-fire season cleaning removes that film and lowers the odor and particulate load in your home.

FAQs About Air Duct Cleaning in Los Angeles
Most Los Angeles homes need air duct cleaning every 3 to 5 years, but older bungalows with gravity floor furnaces and single returns can often go 4 to 6 years because there is less duct surface area collecting dust. Homes near busy corridors like the 110 or the 405, or in neighborhoods with heavy tree pollen like the hills above Los Feliz, may benefit from cleaning every 2 to 3 years. The honest answer is that we will tell you if your system does not need a full cleaning yet, and show you the photos to prove it. Call (737) 727-2314 and we will help you figure out the right interval for your specific home.
Because per-vent pricing is how Los Angeles homeowners get played. A company quotes a low per-vent rate, discovers during the job that your gravity furnace has no accessible trunk line and only three supply registers, and you end up paying more than a straight system quote would have cost. We price the entire system up front, in writing, before any tools come off the truck. The price you sign off on is the price you pay, whether your Los Angeles home has three vents or fifteen.
We connect a Nikro HEPA-rated vacuum to create negative pressure, run a Rotobrush agitation tool through each supply and return, then finish with a camera inspection so you can see the before and after on our tablet. The whole job takes two to four hours for a standard LA home, and you get before-and-after photos of your own duct walls as part of our standard documentation. No shop-vac shortcuts, no blowing dust back into your living room.
Yes, and we recommend it. Dryer vents in Los Angeles collect a specific mix of lint, dust from open windows, and fine particulate from traffic corridors, and a clogged vent is a fire hazard. Adding Dryer Vent Cleaning in Los Angeles to an air duct cleaning typically runs $75 to $150 extra, and we document it with photos the same way we document the duct work.
Because traffic and permit parking on streets like Wilshire or Vermont can turn a 20-minute drive into an hour, and a rushed job is a bad job. We book a real arrival window you can track live through the Relay Standard, and we take the time to set up negative pressure, run the agitation tools properly, and document the work with video and photos. Scheduling is coordinated from our Los Angeles office, so your window is set by people who actually know the neighborhood, not a distant dispatcher guessing at drive times. Call (737) 727-2314 for the next available window.
