Why Altadena Homeowners Choose Bellows Air Duct & Vent Co.
We’ve built our reputation in Altadena the slow way: showing up when we say, doing what we promised, and standing behind it if something’s not right. No coupons that expire the moment you read the fine print. No technician who shows up in an unmarked van and doubles the price at the door.
Our Altadena customers tend to live in the same house for decades. They’ve raised families in the neighborhoods below the San Gabriels, watched the chaparral cycle through dry years and wet ones, and they’ve learned to spot a contractor who talks faster than they work. Bellows doesn’t operate that way. Our 90-Day Done Right Promise is stamped on every job in writing: if the work isn’t right, we return at no charge with no paperwork required.
We serve homes throughout the community, from the tree-lined streets of the Altadena Country Club area to the hillside properties along Fair Oaks Avenue. Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro systems. Most importantly, they answer to a live person at our office 24 hours a day. If you call at 10 PM because your furnace sounds wrong after a cleaning, someone picks up.
We’ve earned our standing in this community through repeat calls and neighbor-to-neighbor referrals. That’s the only marketing that ever lasted in Altadena.
Air Duct Cleaning Services We Offer in Altadena
Air Duct Cleaning
Our complete duct cleaning service removes built-up dust, debris, and contaminants from your entire supply and return system. We camera-inspect before and after every clean, so you see the difference rather than taking our word for it. Learn more about our Air Duct Cleaning in Altadena.
Dryer Vent Cleaning
Lint accumulation in dryer vents creates a genuine fire hazard, particularly in Altadena’s older homes where original vent runs may be longer and more convoluted than modern code allows. We clear the full run from appliance to exterior termination and verify airflow restoration. Learn more about our Dryer Vent Cleaning in Altadena.
HVAC Cleaning
Coils, blower assemblies, and plenums collect debris that reduces efficiency and circulates particulates through your living space. Our HVAC cleaning addresses the full air handling unit, not just the visible surfaces. Learn more about our HVAC Cleaning in Altadena.
Duct Repair & Sealing
Altadena’s original duct systems, especially the fiberglass duct board common in 1960s ranches and the oversized flex runs in older retrofits, degrade and leak over time. We repair separations, seal joints, and restore system integrity so cleaned ducts stay clean and conditioned air reaches its destination - learn more about our Duct Repair & Sealing in Altadena.
Air Quality & Sanitizing
For homes affected by smoke infiltration, mold concerns, or persistent odor issues, we apply EPA-registered sanitizing treatments after mechanical cleaning - see our Air Quality & Sanitizing - Altadena service. This service is particularly relevant in Altadena’s 91001 and 91003 ZIP codes following the Eaton Fire, where combustion byproducts have proven resistant to standard cleaning alone.
Neighborhoods We Serve in Altadena
Our technicians make the run from Bell to Altadena daily, and we’re also serving La Cañada Flintridge, CA, so we know the local streets well enough to give accurate arrival windows. Most Altadena appointments are scheduled within 24 to 48 hours of your call.

Why Altadena’s Climate & Housing Affect Air Duct Cleaning
Altadena sits in a unique position, pressed directly against the San Gabriel Mountain front. This foothill placement makes the community a concentrated impact zone for Santa Ana wind events, which funnel mountain chaparral dust, pollen, and, during fire years, heavy ash loads straight into outdoor air intakes. The particulate burden here is measurably worse than in lower-elevation Pasadena, CA immediately to the south. Even in non-fire years, Altadena ductwork accumulates debris faster than equivalent systems in flatland communities.
The January 2025 Eaton Fire burned through large portions of Altadena, and even homes that survived structurally intact had HVAC systems actively cycling during the firestorm. Those systems pulled sub-micron ash, soot, and combustion byproducts deep into ductwork that now recirculates those contaminants every time the system runs. This post-fire duct contamination crisis is unique to Altadena at a scale no neighboring community shares, making it the defining driver of air duct cleaning demand in ZIP codes 91001 and 91003 right now.
Altadena’s housing stock compounds the challenge. The residential neighborhoods are dominated by Craftsman bungalows and mid-century ranch homes built from the 1920s through the 1960s, many retaining original or early-retrofit duct systems. Degraded fiberglass duct board and oversized flex runs trap particulate and are especially vulnerable to smoke infiltration. These older systems were not engineered to handle the fine particulate loads generated by a wildfire burning immediately adjacent to the neighborhood.
Our technicians working Altadena after the Eaton Fire have found a consistent pattern: homes where the furnace or AC ran during or immediately after the fire event show a distinct grey-black fine-ash coating on the interior of supply ducts all the way to the registers. This contamination is invisible from the return grille but confirmed once our cameras go inside. Standard filter replacement alone cannot address it. Only thorough mechanical cleaning, verified visually, restores these systems to proper function.

FAQs About Air Duct Cleaning in Altadena

Larger homes or properties with dual-zone systems typically fall in the $500 to $650 range. We give you the exact price before we start, and it doesn’t change when we arrive.

Yes, if your HVAC system was running during or immediately after the January 2025 fire, you likely have fine ash and combustion byproducts deposited throughout your supply ducts. Our cameras have found grey-black coating in structurally intact homes across 91001 and 91003. Standard filters cannot remove this contamination once it’s inside the ductwork. We recommend a camera inspection to confirm whether cleaning is needed in your specific system.
In normal conditions, every three to five years is reasonable for most homes. Altadena’s foothill position against the San Gabriels accelerates particulate accumulation, and the Eaton Fire has created an exceptional circumstance for the entire community. Homes in the fire impact zone should be evaluated regardless of when they were last cleaned. After any cleaning, we’ll tell you honestly when we think you should next consider service.
Repair and sealing is usually the more cost-effective path for Altadena’s 1920s through 1960s housing stock, provided the duct board or flex runs haven’t degraded past recovery. We camera-inspect first and give you a straight assessment. Replacement becomes necessary when structural integrity is compromised, but many original systems can be restored to proper function with targeted repairs. Our $50 off any repair over $250 applies to these jobs.
We often can, especially for Altadena appointments. Our technicians make the run daily, and we keep slots open for urgent situations, particularly post-fire contamination concerns where homeowners are experiencing respiratory symptoms or persistent odors. Calls are answered by a live person 24 hours a day. If same-day isn’t available, we typically schedule within 24 to 48 hours.
Ready to schedule? Call (844) 685-6342 for a free estimate. We’ll give you an upfront price, show up when we say, and leave you with camera-verified results and our 90-Day Done Right Promise in writing.

What Altadena Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else uses. The number on the phone was the number on the invoice."
- Dustin Hayes"The allergies in this house had been bad since we moved in. It has been a couple of months since they did the ducts and it is noticeably better. Not a miracle, but real."
- Vikram Rao"Happy with the cleaning itself. The written summary took a few days to arrive after I asked for it, which was slower than I expected."
