Air Duct Cleaning Company in Altadena, CA
Air duct cleaning in Altadena runs from about $450 to $1,200 for a typical single-family home, depending on the number of systems, ductwork condition, and how much wildfire soot has worked its way in. Altadena’s older housing stock and foothill location mean our crews deal with more ash, dust, and aging galvanized ductwork than they see in most Los Angeles County cities. We’re a full-service air duct cleaning company serving Altadena, and you can call us at (626) 469-5477 for a written quote before any work starts.
Why Altadena Homes Are Different
Altadena’s homes are a different animal than what you’ll find down the hill. The mix of 1920s bungalows and mid-century ranch houses means a lot of original ductwork is still in place, and much of it is galvanized steel that has spent 50 to 80 years corroding in crawlspaces. Duct leaks are common, especially where the metal has thinned from moisture and age. When the Santa Ana winds kick up, fine particulates from the San Gabriel foothills get pulled into return-air grilles, and after any significant brush fire in the Angeles National Forest, we see a surge of calls from Altadena homeowners with dark, sooty buildup inside their supply registers. That soot isn’t just on the register face; it coats the full run of duct and keeps recirculating until the system is cleaned and the filtration is checked. Roy Castellanos and our techs know this because we see it in Altadena every fire season.
Styles & brands we work with
Our Main Altadena Services
Three jobs in particular matter here: cleaning the supply and return ducts, clearing dryer vents that run long distances through older crawlspaces and walls, and sealing ductwork that leaks conditioned air into attics and under-floor spaces. Altadena’s older homes mean these three services often work together.
Air Duct Cleaning in Altadena
Older Altadena homes accumulate a mix of construction dust, pet hair, and decades of fine soot from foothill fires. Our process uses a negative-air machine to pull the ductwork under vacuum while a rotary brush system mechanically loosens debris from the duct walls, including the galvanized runs common in 1940s to 1970s homes. Filters are checked as part of the job, since a clogged Aprilaire or Honeywell media filter simply pushes that debris back through the blower. Air Duct Cleaning in Altadena covers the full process and pricing. We leave the site clean and the registers wiped down before we go.
Dryer Vent Cleaning in Altadena
Dryer vents in Altadena often run longer than code would allow today, especially in 1950s ranch houses where the laundry room sits on an interior wall and the vent snakes through the crawlspace to the exterior. Lint buildup in those long runs is a fire hazard and a slow-drying nuisance. We clean the full run from the dryer connection to the outside termination, using professional equipment sized for long, angled routes. Dryer Vent Cleaning in Altadena has the specifics on how we handle extended vent runs and what it costs.
Duct Sealing in Altadena
When ductwork leaks in a crawlspace, you’re paying to heat or cool the underside of the house. In Altadena, many original galvanized ducts have separated at the seams or corroded through in spots, especially where they pass near the foundation. We seal accessible ductwork with mastic, a brush-on or tape-applied sealant that is standard in the trade and far more durable than foil tape alone. Sealing those leaks also keeps ash and dust from being pulled into the system from the crawlspace. Duct Sealing in Altadena details what a sealing job involves and when it makes sense with a cleaning.

Fire season pushes prices up when the system needs a post-wildfire smoke and ash remediation pass, and a two-story home with original galvanized ductwork tends to fall at the higher end because the runs are longer and more fragile. Whatever the number, it’s written down before we start, and it does not move at the door.

FAQs About Air Duct Cleaning Company in Altadena
We typically schedule within one to three business days, but demand in the San Gabriel foothills rises after any significant Angeles National Forest brush fire, so lead time can stretch during those weeks. Call (626) 469-5477 and we’ll give you the next available window and a written price before we arrive.
No. Air duct and dryer vent cleaning, along with duct sealing, are interior maintenance work and do not require a city permit or HOA sign-off in Altadena. If you live in a planned community like La Vina, check with your management office, but we’ve never had an HOA object to this type of service.
Yes, and it’s common. Many Altadena homes built through the 1950s had heating-only ductwork that was later retrofitted for cooling, which often means undersized and corroded galvanized runs. We inspect the system before cleaning and will tell you if the ductwork needs sealing or repair first; the price is written down before any work begins.
