Fast, Reliable HVAC Cleaning Across Altadena
Altadena homeowners have been calling us for over 42 years when their heating and cooling systems need more than a filter swap. We’re located in Los Angeles and typically reach Altadena homes within 45 minutes, whether you’re in the historic bungalows near Mariposa Street, the hillside estates above Loma Alta Drive, or the mid-century ranches along Lake Avenue. After the January 2025 Eaton Fire, the calls changed. Now we’re hearing from families whose ducts pulled in toxic smoke and ash, and they need someone who understands what that means for a 1920s Craftsman with original galvanized ductwork. If your vents smell like smoke when the system cycles, or you’re noticing gray dust settling on furniture after running the AC, call HVAC Cleaning in Altadena specialists at (855) 401-6006. We’ll answer, we’ll listen, and we’ll get there when we say.
Why Bellows Air Duct & Vent Co. of California Is Altadena’s Preferred HVAC Cleaning Company
We’ve been serving unincorporated Los Angeles County communities since 1984, and Altadena has always been a significant part of our route. Roger Castañeda leads our operation with a straightforward philosophy: show the homeowner exactly what’s in their ducts before touching anything, quote one price that doesn’t change, and stand behind the work for 90 days with no paperwork if something’s not right.
Our technicians know the local housing stock. They’ve cleaned systems in the 91001 ZIP around Christmas Tree Lane and the 91003 foothill properties where duct runs stretch across multiple levels and crawl spaces. They understand that a standard residential cleaning setup won’t handle post-wildfire contamination, and they carry HEPA-rated equipment from Rotobrush and Abatement Technologies specifically for these conditions - the same standards we apply to our Air Quality & Sanitizing - Altadena service.
Calls are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. Most jobs are completed in a single visit by background-checked, uniformed technicians who arrive when scheduled. Our 90-Day Done Right Promise is stamped on every job: if it’s not right, we make it right, no arguing, no forms to fill out.
We also honor a permanent 5% Senior and Veteran discount, and we currently offer a $89 Seasonal Tune-Up to help Altadena families assess their systems before peak summer demand.
Our HVAC Cleaning Services in Altadena
Evaporator Coil Cleaning
The evaporator coil in your indoor air handler is where cooling actually happens, and in Altadena it’s working harder than most. The foothill elevation means cooler nights that cause more frequent HVAC cycling year-round, and each cycle pulls outdoor particulates through the system. After the Eaton Fire, we’re finding coils coated with fine ash that restricts heat transfer and forces your compressor to run longer. Our process uses foaming cleaners and low-pressure rinses that won’t damage aging aluminum fins, followed by camera verification so you see the difference. A typical evaporator coil cleaning in Altadena runs $180-$290.
Blower Cleaning
The blower motor and wheel push conditioned air through every room, and when they’re dirty, you feel it in uneven temperatures and higher electric bills. In Altadena’s older homes, especially the Spanish Colonial Revival cottages near Mendocino Street, blowers often run in cramped attic spaces where decades of dust have packed into the wheel vanes - a problem we also address with our Altadena Dryer Vent Cleaning service, since the same lint accumulation happens in dryer systems. Post-fire, that dust is mixed with ash. We remove the blower assembly, clean it outside the duct system to prevent recontamination, and balance it before reinstallation. Blower cleaning in Altadena typically costs $150-$240.
Condenser Cleaning
Your outdoor condenser coil takes the heat your indoor system collects and dumps it outside. Altadena’s position at the mouth of San Gabriel Mountain canyons means Santa Ana wind events drive oak debris, pollen, and grit directly into that coil fins. During fire season, ash clogs the fins and insulates them, reducing efficiency by 20% or more. We use foaming cleaners and fin combs to restore airflow without damaging the delicate aluminum. Most condenser cleanings in Altadena run $140-$220, with additional charge if the unit requires disassembly for deep cleaning.
Air Handler Cleaning
The air handler is the central station of your HVAC system, housing the blower, coil, and often the filter rack. In Altadena’s 1940s-1950s ranch homes, these units frequently sit in closet-sized spaces with minimal access, and they’ve rarely been opened for thorough cleaning. We cleaned a 1940s Spanish Colonial Revival on Loma Alta Drive where the flex duct was packed with fine gray-black ash from the Eaton Fire; our HEPA-rated Rotobrush and Abatement Technologies HEPA-AIRE filtered 4.5 pounds of hazardous particulates from a system that had never been professionally serviced. That level of contamination is why we recommend Air Duct Cleaning in Altadena as a priority after fire events. Air handler cleaning in Altadena ranges from $220-$380 depending on unit size and accessibility.

Trusted Brands We Service in Altadena
We specify professional-grade equipment from Rotobrush, Abatement Technologies, and Aprilaire, the same brands serious HVAC contractors use for commercial and institutional work. For Altadena homeowners dealing with post-fire contamination, this matters. Standard residential vacuums recirculate fine particulates through their exhaust; our HEPA-AIRE systems from Abatement Technologies capture particles down to 0.3 microns at 99.97% efficiency. We stock common replacement parts locally, so if your cleaning reveals a failing component, we can often complete the repair same-day rather than ordering parts and rescheduling. Our HVAC Cleaning team carries Rotobrush brush systems in multiple diameters to accommodate the older, smaller ductwork common in Altadena’s pre-1960 housing stock.
Common HVAC Cleaning Problems We See in Altadena Homes
- Using standard vacuum equipment on post-fire ash. We’ve been called in after other cleaners ran standard shop vacuums through ducts contaminated with Eaton Fire residue. The exhaust blew fine ash back into living spaces. Only HEPA-rated gear with sealed containment meets this hazard.
- Cleaning only the main trunk duct while ignoring buried supply runs. Altadena’s older homes, especially those with crawl spaces beneath original 1920s-1950s construction, have supply lines that run through inaccessible areas. Leaving these untouched means decades of debris and now wildfire ash remain in the system.
- Failing to test for residual combustion byproducts after cleaning. Smoke residue contains VOCs and soot staining that visual inspection misses. We verify results with camera documentation and, for post-fire jobs, recommend third-party air quality testing to confirm the home is truly safe.
- Assuming aging galvanized ductwork must be replaced. Many Altadena homeowners have been told their original metal ducts are too far gone. In most cases, thorough mechanical cleaning followed by proper sealing restores function at a fraction of replacement cost. We show you the camera footage and let you decide.

FAQs - HVAC Cleaning in Altadena
No. Standard residential duct cleaning equipment is not designed to capture the fine particulates and toxic combustion byproducts, including potential asbestos and lead paint residues, that the Eaton Fire deposited in Altadena homes. We use HEPA-rated Abatement Technologies systems with sealed containment and proper disposal protocols for post-fire jobs. Call (855) 401-6006 to discuss whether your home needs this level of decontamination - estimates are free.
In most cases, original galvanized ductwork can be cleaned effectively and sealed rather than replaced. We’ve restored dozens of Altadena systems from the 1920s-1950s era, and full replacement typically costs 3-5 times more than professional cleaning with Aeroseal or mastic sealing. We show you camera footage of the interior before and after so you can make an informed decision. Call (855) 401-6006 for a free inspection and honest assessment.
The filter protects the equipment, but it doesn’t clean what’s already inside your ducts, blower, and coil. In Altadena, Santa Ana winds drive outdoor particulates through any gap in your system’s envelope, and older homes have plenty. If you’re changing filters regularly but still seeing dust, the contamination is downstream of the filter. A full HVAC cleaning addresses the source. Call (855) 401-6006 and we’ll trace it.
For standard conditions, every 3-5 years is typical. After a significant wildfire event like the Eaton Fire, homes in the burn scar or downwind plume areas should be evaluated immediately, even if the house itself didn’t burn. Altadena’s foothill location and canyon wind patterns create higher ongoing particulate exposure than lower-elevation neighbors, so we recommend annual HVAC inspections for homes in the 91001 and 91003 ZIP codes. Our $89 Seasonal Tune-Up includes a basic duct assessment. Call (855) 401-6006 to schedule.
Yes. If your system was running during or shortly after the fire, or if outdoor intake seals are compromised, ash and particulates are likely present in the ductwork. Turning on the system without professional cleaning can redistribute these materials throughout your home. We recommend a pre-season inspection before first use, especially for homes near burned structures where toxic combustion byproducts are a documented hazard. Call (855) 401-6006 - we’ll prioritize these calls and get there quickly.
