Why Bellows Air Duct & Vent Co. of California Is Alum Rock’s Preferred HVAC Cleaning Company
We’ve worked the 95127 ZIP for four decades. That means we’ve cleaned the original ductwork in the postwar tracts off Alum Rock Avenue, the ranch homes near Mount Pleasant High School, and the hillside places along Alum Rock Road where the wind hits first. Roger Castañeda built this company on showing up when promised and standing behind the work - no paperwork, no arguing. Our 90-Day Done Right Promise is stamped on every job.
Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro HEPA vacuum systems. Every clean includes camera inspection before and after, so you see what we see. We don’t bait with coupons and change the price at the door. The number we give on the phone is the number on the invoice.
Calls ring to a live person, not a menu tree. That’s been true since 1984, and it’s still true at 2 AM when smoke smell is pushing through your vents after a wind event.
Our HVAC Cleaning Services in Alum Rock
Evaporator Coil Cleaning
Alum Rock’s foothill position means your evaporator coil works harder than coils in flat San Jose. Diablo wind events pull fine particulate through aging duct seams, and that debris settles on wet coil fins - cutting efficiency and forcing your compressor to run longer. We clean coils with foaming cleaner and low-pressure rinse, then verify airflow recovery with our camera system. A typical evaporator coil cleaning in Alum Rock runs $180-$320.

Blower Cleaning
The blower assembly is where smoke-stained debris collects after wildfire season. In homes near Alum Rock Park, we’ve pulled blower wheels caked with gray-brown residue that standard filters never caught because it entered through separated duct joints behind the filter. We remove the blower housing, clean the wheel and motor housing with HEPA-contained vacuums, and balance the assembly on reassembly. Most blower cleanings in Alum Rock are $150-$275.

Condenser Cleaning
Your outdoor condenser sits in the same wind path. Grassland pollen from the Diablo Range foothills, dust from dry creek beds, and ash particulate all pack into coil fins. We use foaming cleaner and fin combs, not pressure washers that bend delicate aluminum. A clean condenser in Alum Rock’s hot summers can drop head pressure significantly. Condenser cleaning typically runs $120-$220 here.

Air Handler Cleaning
The air handler is the heart of your system, and in Alum Rock’s 1950s-1970s homes it’s often never been opened. We clean the entire cabinet, drain pan, and secondary components, then treat with antimicrobial where appropriate. For homes with original sheet-metal ductwork, this is where we often find the first evidence of smoke infiltration - staining on the filter rack and cabinet interior that tells the story of what got past your filter. Air handler cleaning in Alum Rock generally costs $200-$380.

Heat Exchanger Cleaning
Furnace heat exchangers in older Alum Rock homes require careful inspection and cleaning. Decades of combustion byproducts, combined with restricted airflow from dirty ductwork, can stress these components. We inspect with cameras before cleaning, and if we find cracks or deterioration, we’ll show you exactly what we found. Heat exchanger cleaning runs $220-$400 in this market.

Coil Treatment
After cleaning, we offer protective coil treatment that helps repel future particulate buildup. In Alum Rock’s fire-prone environment, this extra layer matters. Treatment adds $45-$85 to any coil service.

Trusted Brands We Service in Alum Rock
We carry equipment and replacement media from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify. For Alum Rock homeowners with whole-house air cleaners, we stock Aprilaire and Honeywell filter media, so you’re not waiting on a warehouse shipment while smoke season approaches. Our technicians arrive with the parts to complete most jobs in one visit, because we know a second trip means more time with compromised air in your home.
Common HVAC Cleaning Problems We See in Alum Rock Homes
- Original cloth-backed tape joints fail with age, allowing unfiltered wildfire smoke and Diablo wind particulates to bypass the filter and settle directly on evaporator coils. We find this in nearly every pre-1980 home we open in 95127.
- Flex connection separations at plenums create low-pressure zones that pull untreated attic air into the system. In homes near Alum Rock Park, this compounds smoke staining because attic vents face the same wind direction as the house.
- Collapsed inner duct liners in 1950s-1970s homes restrict airflow and trap smoke particles deep in the system. Cleaning can’t restore performance here - the liner needs replacement, which we’ll document with camera footage before recommending.
- Undersized filter racks on original systems can’t accommodate modern MERV-13 media that would actually catch wildfire particulate. We retrofit proper filter housings so your next filter upgrade fits and seals.

FAQs - HVAC Cleaning in Alum Rock
Your aging duct seams are pulling in smoke particulates that bypass your filter entirely. Alum Rock’s position against the Diablo Range places it directly in smoke drift paths that flat west San Jose never sees, and original cloth-backed tape joints in 1950s-1970s homes have hardened and cracked, creating infiltration points. On a 1960s tract home near Alum Rock Park, our crew found original sheet-metal ductwork with cloth-backed tape joints that had separated, pulling in smoke-stained debris from the 2020 SCU Lightning Complex fire. We cleaned the system with a Rotobrush HEPA vacuum, repaired the duct seams with mastic and foil tape, and replaced the filter with a MERV-13 Aprilaire - preventing re-infiltration during next fire season. Call (855) 401-6006 and we’ll camera-inspect your system to find exactly where the smoke is entering.
Yes, if the metal is intact and the joints can be sealed - which is true for most homes we see in 95127. Original sheet-metal ductwork is actually more durable than modern flex duct; the problem is the sealing, not the metal. We clean the system, reseal joints with mastic and foil tape, and verify with camera. Only if inner liners have collapsed or rust has compromised the metal do we recommend replacement. A full cleaning and reseal in a 1960s Alum Rock home typically runs $400-$750, versus $2,000+ for full duct replacement. Call for a free inspection and we’ll show you which category you’re in.
We see demand spike 48-72 hours after major Diablo wind events, especially in September through November. The winds funnel through Alum Rock Creek canyon and adjacent gaps, pulling particulate concentrations higher than central San Jose. If you smell smoke or see dust settling faster after a wind event, don’t wait - particulates that enter through compromised ductwork begin embedding in coils and blower components within days. We maintain emergency scheduling for Alum Rock foothill homes during fire season. Call (855) 401-6006 and we’ll prioritize your inspection.
Yes - we service both brands regularly in Alum Rock homes. We clean or replace the media in your whole-house unit as part of system service, and we verify that the unit is actually sealing and drawing air properly. Sometimes we find that a whole-house cleaner was installed on a system with leaking ductwork, meaning it never had a chance to work effectively. We fix the duct leaks first, then optimize the cleaner. Mention your unit when you call and we’ll bring the correct replacement media.
Failed cloth-backed tape joints at plenum connections and flex duct transitions. This tape was never meant to last 50-70 years, and in Alum Rock it degrades faster due to temperature swings from Diablo wind events and occasional smoke exposure. The result is visible smoke staining on filter racks and blower components, plus reduced airflow that strains your HVAC system. We repair these joints with mastic and foil tape as standard practice during every cleaning. Call (855) 401-6006 for a free camera inspection - we’ll show you exactly what condition your joints are in.
