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.
Fast, Reliable Air Duct Cleaning Across Altadena
Air duct cleaning in Altadena typically runs $450 – $900 for a full system on a standard single-family home, with older foothill properties sometimes reaching $1,100 when asbestos identification and duct sealing are required. After the January 2025 Eaton Fire, the job here is different from anywhere else in LA County: the ducts in surviving homes are holding smoke, ash, and fire-retardant residue that keeps off-gassing months later. We know Altadena’s homes, its wind patterns, and exactly what it takes to clear a system that’s been through what yours has. Call (980) 447-2498 and we’ll walk you through what we’d do, what it costs, and when we can get there.
Why Linden Air Duct Cleaning Is Altadena’s Preferred Air Duct Cleaning Company
Altadena homeowners call us for Altadena Air Duct Repair because the technician who shows up is the person whose name and photo we sent you the day before. Every one of our techs is background-checked, identity-verified, and photo-badged under the Threshold Standard. You’ll know who’s at the door before you open it. That matters here, now, more than ever: after the Eaton Fire, hundreds of crews from outside the area flooded in. We did not. We sent verified technicians who live and work in this region, who understand what a 1947 Spanish Colonial Revival off Ventura Street looks like inside its ductwork.
We’ve been part of the Threshold Group family since 2004. That’s two decades of standing behind every job with a written price before any work starts and a written guarantee on every repair. Marcus Veale leads our team, and the commitment is simple: if the work isn’t right, we make it right, backed in writing for 365 days. That’s not a promotional line. It’s the 365-Day Done Right Promise, and it applies to every single job we do in Altadena.
When you call (980) 447-2498, a live person answers. Not a voicemail loop, not an automated callback queue. Day, night, weekend, it does not matter. You speak to a human who can schedule your Air Duct Cleaning visit or answer a question about what we found in a neighbor’s system down the street.
Air Duct Cleaning Services in Altadena
Air Duct Cleaning Services in Altadena are, right now, primarily a post-disaster remediation job. Our Air Duct Cleaning team starts with a camera inspection of the supply and return runs, then sets up negative-pressure extraction with HEPA filtration so debris, ash, and char stay contained while we work. We agitate the duct walls with professional Rotobrush equipment, pull the loose material out, and document what we remove. In Altadena’s pre-1980s homes, we always check for asbestos-containing insulation wrap before any agitation begins. If it’s present, we stop and refer you to a licensed abatement specialist before we touch the system. A typical full-system cleaning in Altadena runs $450 – $900, depending on the home’s square footage, number of returns, and how much post-Eaton residue has settled inside.
Residential Duct Cleaning
For Altadena’s 1920s – 1950s Craftsman bungalows and Spanish Colonial Revivals, residential cleaning means dealing with decades of accumulated debris, often poor past patching, and now a layer of wildfire smoke particulate. We clean supply and return ducts, inspect for disconnected or crushed flex runs, and seal what we can access. The price we quote is the price you pay, in writing, before work begins.

Post-Eaton Fire Remediation
This is the specific job Altadena needs. HEPA room purifiers cannot reach char embedded inside duct liner. The only fix is source removal: cleaning the ducts themselves so the off-gassing stops at the source. We run negative pressure throughout, so what we dislodge leaves through the HEPA filtration system, not back into your living room.

HVAC Duct Cleaning in Altadena
HVAC Duct Cleaning in Altadena means working on systems that sit at the base of the San Gabriel Mountains, where Santa Ana winds push chaparral dust, smoke, and fine ash into homes at concentrations far higher than in the Pasadena flatlands below. Our techs clean the full HVAC pathway: supply plenum, return boots, registers, and the trunk lines that feed every room. In post-Eaton homes, we’re frequently finding acrid residue inside duct liner and insulation that only mechanical agitation plus HEPA capture can remove. Expect $450 – $900 for a complete HVAC duct cleaning in Altadena, with the range driven mainly by home size and system accessibility.
Supply and Return Duct Cleaning
Supply ducts deliver the air you breathe; return ducts pull it back. Both are equally contaminated after a fire event, and both need to be cleaned. In Altadena’s older homes, we often find return ducts that were never properly sealed after a remodel, which means they’ve been pulling debris from crawlspaces and wall cavities for years.
Full System Cleaning with Video Inspection
Before we clean, we send a camera through your ducts so you can see what’s actually in there. After we finish, we run it again. You’ll see the difference. This is standard on every job in Altadena, not an upsell.
Trusted Brands We Service in Altadena
Our equipment is professional-grade and built for the Specific conditions Altadena throws at us. We run Rotobrush and Nikro negative-pressure systems for extraction, and for air-quality improvements we install and service products from Aprilaire, Honeywell, Abatement Technologies, and Guardsman. If you’re in the Lake Avenue corridor or up near Altadena Drive, you don’t have to wait on parts from a distributor across the county. We keep common components stocked and ready. And if your existing Aprilaire or Honeywell system needs attention during a cleaning visit, we’ll tell you before we do anything and give you a written price first.
Common Air Duct Cleaning Problems We See in Altadena Homes
- Post-Eaton Fire char and smoke residue embedded in duct liner. This is the defining issue in Altadena right now. Room air purifiers cannot reach it. The material inside the ducts keeps releasing odor and particulates until it is mechanically removed at the source.
- Crushed or disconnected flex-duct runs behind remodels. In 1920s – 1950s Craftsman bungalows, decades of kitchen and bath remodels have left original runs patched, kinked, or fully separated. Air that should reach a bedroom is instead dumping into the wall cavity or crawlspace.
- Asbestos-containing insulation wrap on pre-1980s ductwork. Any disturbance of this material without identification first is dangerous. We always inspect before agitating. If we find it, we stop, explain what’s there, and refer you to a licensed specialist.
- Fine chaparral dust from Santa Ana wind events. Altadena’s position at the alluvial base of the San Gabriels means every downslope wind event pushes fine particulate into homes. Even outside of fire years, systems here clog faster than in Pasadena, San Marino, or South Pasadena.
Pricing for Air Duct Cleaning in Altadena, CA
A full air duct cleaning on a standard Altadena single-family home runs $450 – $900. Larger homes, or systems with multiple returns and hard-to-access crawlspace runs, can reach $1,100. If asbestos identification reveals the need for abatement before cleaning, that’s handled by a separate licensed specialist and quoted by them. What affects your price: square footage, number of supply and return runs, accessibility of the ductwork, and how much post-Eaton residue has accumulated. You’ll get a written price before any work starts, every time. Call (980) 447-2498 for a free estimate specific to your home, not a range from a brochure.

FAQs About Air Duct Cleaning in Altadena
Because smoke, ash, and fire-retardant residue entered every home downwind, not just the ones that burned. In surviving homes, this material settled inside ducts, liners, and insulation where room purifiers cannot reach it. The result is ongoing odor and particulate release. The fix is source removal: cleaning the ducts themselves. Call (980) 447-2498 and we’ll explain what a camera inspection would show in your system.
Yes, with one critical step. We inspect the duct insulation before any agitation begins. If it’s pre-1980s wrap that may contain asbestos, we do not disturb it. We stop the cleaning, tell you what we found, and refer you to a licensed abatement specialist. Only after that material is addressed by a professional do we return to clean the system safely.
They make it more frequent. Altadena sits at the alluvial base of the San Gabriel Mountains, directly in the path of downslope wind events that carry chaparral dust, fine ash, and smoke particulate into homes faster than in the flatlands below. Even in years without a major fire, systems here accumulate more debris than in Pasadena or San Marino. Many Altadena homes benefit from inspection every 2 – 3 years, and sooner after a significant wind-driven fire event.
Real problems you cannot see from the register: crushed flex runs behind remodels, disconnected joints pulling crawlspace air into the return, decades of caked debris, and now a layer of post-Eaton char and smoke residue. The camera also documents what the ducts looked like before and after we clean, so you know the work was actually done. It’s standard on every job.
We follow NADCA standards for source removal: negative-pressure extraction with HEPA filtration, mechanical agitation of duct walls, and documentation of the system before and after. Our equipment is Rotobrush and Nikro, both built for containment and capture. The tech’s name and photo are sent to you before the visit, and a photo ID badge is shown at the door.
