Why Bellows Air Duct & Vent Co. of California Is East Palo Alto’s Preferred HVAC Cleaning Company
East Palo Alto homeowners call us back because we treat their older systems with the patience they require. We’ve cleaned coils in the original 1950s ranches near Bell Street, resealed flex duct in garage conversions off Newell Road, and pulled decades of bay sediment from air handlers in the long-term rentals along Woodland Avenue. Our technicians are background-checked, uniformed, and equipped with camera inspection gear from Rotobrush and Nikro - we show you the before and after, not just tell you.
Our office picks up the phone around the clock. No app. No voicemail tree. If your blower quits on a Saturday night or your evaporator coil ices over during a marine-layer morning in East Palo Alto, you’ll reach a live person who can dispatch a crew. Most East Palo Alto calls get same-day or next-day service.
The 90-Day Done Right Promise applies to every job in 94303. If something isn’t right, we return at no charge. No paperwork to file, no arguing. Roger Castañeda put that in writing when he founded Bellows in 1984, and it’s still how we operate.
Our HVAC Cleaning Services in East Palo Alto
Evaporator Coil Cleaning
The evaporator coil is where East Palo Alto’s unique contamination pattern does its worst damage. Bay sediment, salt, and marsh allergens bypass compromised filters in older ductwork and pack onto the coil fins, cutting airflow and forcing your compressor to run longer. In East Palo Alto’s humid marine-layer conditions, that same debris holds moisture long enough to start mold colonization on the coil pan. We clean with foaming agents and low-pressure rinses that won’t bend the fins on these older systems, then camera-verify the full length. A typical evaporator coil cleaning in East Palo Alto runs $180-$340.
Blower Cleaning
The blower wheel and housing collect everything the filter misses, and in East Palo Alto homes with original or poorly sealed ductwork, that’s a lot. A dirty blower draws more amps, runs hotter, and shortens the motor’s life - a real concern in homes where the HVAC unit itself is original to the 1960s or 1970s construction. We remove the blower assembly when accessible, clean the wheel vanes and housing with professional-grade equipment, and balance it before reinstallation. Most blower cleanings in East Palo Alto fall between $160-$290.
Condenser Cleaning
Outdoor condenser coils in East Palo Alto face a double hit: the same salt-laden bay air that corrodes duct connectors also coats the aluminum fins, and the dried vegetation from nearby marshland clogs the coil guard. We use foaming cleaners that lift salt residue without etching the metal, then straighten any bent fins for proper heat rejection. This is especially important for homes near the Bayfront Expressway or the eastern edge by Ravenswood Slough, where the exposure is direct. Condenser cleaning in East Palo Alto typically costs $140-$260.
Air Handler Cleaning
The air handler is the central station - blower, coil, filter rack, and drain pan all in one cabinet. In East Palo Alto’s post-WWII tract homes, these units often sit in closets or garage conversions where access is tight and the surrounding ductwork has been modified by hand. We clean the full cabinet interior, treat the drain pan to prevent algae and mold in the humid bay climate, and inspect every connection with a camera scope before we close it up. Air handler cleaning runs $220-$380 in East Palo Alto, with combined coil and blower service often bundled for savings.
Duct Sealing and Reseal
This is where East Palo Alto’s housing stock forces our hand more often than in neighboring cities. Original 1970s spiral foil flex duct, informal garage conversions, and decades of deferred maintenance leave connections open and pathways exposed. We can’t effectively clean what we can’t seal. Our crews carry mastic, metal tape, and replacement flex sections from Abatement Technologies to close gaps before the main cleaning begins. Duct sealing in East Palo Alto ranges from $200-$450 depending on linear footage and accessibility.

Trusted Brands We Service in East Palo Alto
We clean and service equipment from every major manufacturer found in Peninsula homes, and we stock common parts for faster turnaround on East Palo Alto jobs. Our cleaning equipment comes from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify when they install new systems. For coil treatments and sanitizing, we use Guardsman products formulated for residential air handlers. If your East Palo Alto home has a Carrier, Trane, Lennox, Goodman, or older Bryant unit, we’ve worked on it before. We don’t guess at compatibility, and we don’t order parts that keep you waiting.
Common HVAC Cleaning Problems We See in East Palo Alto Homes
- Collapsed 1970s spiral foil flex duct at bends and connections. The combination of age, bay moisture cycling, and informal room additions means we frequently find flex duct that has fully separated inside walls. Our camera scope hits a dead end, and we have to open the connection and reseal before cleaning can continue.
- Bay sediment and salt bypassing filters through unsealed duct connections. In homes with garage conversions or added rooms, the flex duct was often connected by hand without proper sealing. Fine particulate from the tidal flats pulls straight through these gaps and packs onto the evaporator coil, accelerating corrosion and reducing airflow.
- Salt-laden air corroding metal duct connectors and dampers. East Palo Alto’s position downwind of Ravenswood Slough means salt exposure that inland Peninsula cities simply don’t experience. We find rusted damper blades and degraded flex-duct collars that leak conditioned air and draw in contaminated attic or crawl space air.
- Marine-layer humidity encouraging mold in older uninsulated ductwork. Overnight humidity in East Palo Alto runs higher than in San Jose or even Redwood City. Metal ductwork without modern insulation lining develops condensation that supports dust mites and mold, especially in long-vacant rental units where the system sat idle.

FAQs - HVAC Cleaning in East Palo Alto
East Palo Alto sits directly downwind of the San Francisco Bay’s tidal flats and Ravenswood Slough, where prevailing westerly winds push fine dried bay sediment, marsh allergens, and salt-laden air into intake grilles at rates far higher than in neighboring Palo Alto or Menlo Park. Your friend’s home a few miles west or inland doesn’t receive this same particulate load, and Palo Alto’s housing stock has seen more frequent HVAC upgrades and duct maintenance. If your system hasn’t been professionally cleaned in years, the difference is real and measurable. Call (855) 401-6006 for a free camera inspection and we’ll show you exactly what’s inside.
We can clean them only after we repair them - crushed or separated flex duct blocks our cleaning equipment and would simply redistribute debris into your living space. This is one of the most common findings in East Palo Alto’s post-WWII tract homes, where 1970s-era spiral foil flex has collapsed at bends or pulled loose at connections, especially in garage conversions and informal additions. We reseal or replace damaged sections with proper materials before proceeding with the full cleaning. The repair cost is included in your upfront quote, not added later. Call (855) 401-6006 and we’ll scope the ductwork first.
Look for rust staining around metal duct joints, a persistent metallic or musty smell when the system runs, or uneven airflow between rooms that worsened gradually. Salt corrosion from Ravenswood Slough air attacks damper blades, flex-duct collars, and sheet-metal connections first - components that are hidden from view but detectable with a camera scope. We inspect every East Palo Alto job before and after cleaning, and we’ll show you the corrosion we find. If the damage is advanced, we’ll recommend repair options with prices before any work begins. Call (855) 401-6006 to schedule.
It’s a common problem in East Palo Alto, where many post-WWII homes gained informal additions or garage conversions over the decades. The added ductwork was often connected by hand without proper sealing, creating gaps that bypass the filter and draw in attic dust, garage fumes, or bay sediment directly. Our camera inspection identifies these bypass pathways, and we reseal them with mastic and proper flex connections before cleaning the system. This is standard procedure for our East Palo Alto work, not an upsell. Call (855) 401-6006 for a free estimate.
We clean with Rotobrush brush-and-vac systems and Nikro HEPA-filtered extractors for debris removal, and we carry Abatement Technologies replacement duct materials for on-the-spot repairs. For coil treatments and sanitizing, we use Guardsman products. These are the same brands specified by professional HVAC contractors, not discount equipment that leaves residue or misses corners. Every East Palo Alto job is camera-inspected with equipment that records what we find and what we leave behind. Call (855) 401-6006 to see the difference professional-grade tools make.
