We’ve been driving out to East Palo Alto since 1984, back when the city was still building out its post-war neighborhoods and most of the ductwork we see today was brand new. Now those same galvanized trunk lines are pushing sixty or seventy years old, and the bay moisture that seeps in from the South Bay shoreline has had decades to do its work. We know the difference between a home off University Avenue near the freeway and one back in the Gardens neighborhood closer to the water. That local knowledge matters when we’re diagnosing why your vents smell musty in January or why your system runs constantly without catching up.

Response time to East Palo Alto averages under an hour during business hours, and our after-hours emergency line routes to a live person, not a voicemail tree.

Our Air Duct Cleaning Services in East Palo Alto
Residential Duct Cleaning
East Palo Alto’s housing stock is dominated by modest post-WWII tract homes built from the 1940s through the 1960s as workforce housing. Many still have original or lightly modified sheet-metal duct systems that have gone decades without professional cleaning. We use Rotobrush and Nikro equipment designed to navigate these older configurations without damaging fragile joints or disturbing asbestos-wrapped plenums where present. A typical residential duct cleaning in East Palo Alto runs $280-$450 for a single-system home, with larger split systems or homes with basement and attic runs reaching $520-$580.

Commercial Duct Cleaning
The commercial buildings along University Avenue and in the industrial pockets near the bay often share the same moisture challenges as residential properties, but at scale. We clean ductwork for small offices, retail spaces, and multi-unit properties in East Palo Alto with the same camera-verified approach. Commercial jobs start around $680 and scale based on square footage and system complexity. We schedule around your business hours to avoid disrupting operations.

Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms, and in East Palo Alto’s older homes, they’re often the original galvanized runs with decades of accumulated debris. We see supply lines partially blocked by collapsed flex-duct splices, biological growth from condensation, and construction debris from unpermitted renovations. Cleaning supply ducts alone typically runs $180-$320, though we generally recommend full system cleaning to address the root cause rather than treating symptoms.

Return Duct Cleaning
Return ducts pull air back to your air handler, and in EPA’s low-lying homes, they’re the primary entry point for humid, salt-laden bay air. Return duct cleaning in East Palo Alto costs $160-$290 and often reveals the most significant accumulation - these are the pathways drawing air through crawl spaces and wall cavities where moisture and contaminants concentrate. We inspect returns with our video system to identify leaks that would recontaminate the system within months.

Full System Cleaning
Our most comprehensive service for East Palo Alto homes. We clean supply and return ductwork, registers, grilles, and the air handler cabinet, then camera-verify every run. Full system cleaning addresses the interconnected nature of legacy ductwork where contamination in one section recirculates throughout. Typical range: $380-$580. We recommend this for any EPA home that hasn’t had professional duct cleaning in five or more years, or where musty odors persist despite filter changes.

Video Inspection
Every job includes camera inspection before and after. For East Palo Alto homeowners who want to assess their system without committing to full cleaning, we offer standalone video inspection at $149, applied toward cleaning if you proceed. You’ll see exactly what we see: the debris, the moisture staining, the poorly sealed joints, the original trunk lines still in service decades past their intended lifespan.

Trusted Brands We Service in East Palo Alto
We clean and service ductwork connected to all major HVAC brands, and we specify professional-grade equipment from Nikro, Honeywell, and Aprilaire for our own work. These are the same brands serious HVAC contractors specify for remediation and air quality projects. For East Palo Alto customers, this means we don’t need to special-order parts or delay jobs waiting for equipment. Our trucks carry Rotobrush systems, HEPA-filtered vacuums, and sanitizing equipment ready for the specific challenges of bay-adjacent ductwork. When we find a failed component during cleaning - a corroded damper, a disconnected flex duct, a compromised seal - we can address it in the same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in East Palo Alto Homes
- Original galvanized trunks left in place during HVAC upgrades. We regularly find 1950s-era galvanized trunk lines still connected to modern air handlers, packed with decades of debris and biological growth that the new equipment has been recirculating ever since. The homeowner thought they got a new system; they got new equipment on old infrastructure.
- Condensation from marine air penetration. East Palo Alto’s low elevation and proximity to the South Bay shoreline means onshore bay winds push salt-laden, humid marine air directly into crawl spaces and attic chases where most duct runs are located. This promotes condensation on metal duct surfaces and sustains mold colonies even outside the rainy season.
- Poorly sealed flex-duct splices from unpermitted modifications. Many of EPA’s older homes were acquired as rentals over decades and had HVAC systems upgraded without anyone pulling permits or replacing the underlying duct network. Technicians frequently find flex duct spliced into original runs with tape that’s failing, creating leak points that bypass cleaning efforts and allow moisture infiltration.
- Biological growth in returns drawing from damp crawl spaces. Return ducts in East Palo Alto homes often run through or alongside crawl spaces that never fully dry. The result is sustained microbial growth that standard filter changes cannot address and that continues to circulate until the ductwork is professionally cleaned and sealed.

Each city presents different housing stock and climate conditions, and we adjust our approach accordingly.

FAQs - Air Duct Cleaning in East Palo Alto
East Palo Alto’s bay-adjacent position at low elevation creates persistently higher indoor humidity than neighboring Palo Alto or Menlo Park, which accelerates mold and microbial growth inside aging post-WWII ductwork. The salt-laden marine air that penetrates crawl spaces and attic chases sustains condensation on metal ducts year-round, making cleaning a genuine indoor air-quality remediation need rather than simple dust removal. If your home smells musty when the system runs, that’s biological activity, not ordinary household dust. Call (844) 685-6342 for a video inspection and we’ll show you exactly what’s inside your ducts.
Professional duct cleaning eliminates the biological growth and accumulated debris causing musty odors, but only if the underlying moisture intrusion is also addressed. We frequently find that musty smells return within months when cleaning is performed without sealing the poorly spliced flex-duct joints or compromised trunk line connections that allow humid bay air to re-enter the system. Our full system cleaning includes identifying these access points and recommending appropriate sealing - sometimes during the same visit, sometimes as a follow-up repair. The $149 video inspection will reveal whether your odor issue is a cleaning job, a sealing job, or both. Call for a free assessment.
For East Palo Alto homes with original or legacy ductwork in the bay moisture zone, we recommend professional cleaning every 3-4 years rather than the standard 5-7 year interval for drier inland climates. Homes with recent water intrusion, visible mold, or occupants with respiratory sensitivities may need more frequent service. The persistent humidity here simply accelerates accumulation beyond what the standard schedule accounts for. We also recommend annual filter changes with high-quality media and periodic video inspection to catch developing issues before they require remediation. Call (844) 685-6342 to set up a cleaning schedule that matches your home’s conditions.
We do not disassemble original galvanized trunk lines or rigid ductwork as part of standard cleaning - the risk of damaging aged metal or disturbing asbestos-wrapped components exceeds any benefit. Instead, we use Rotobrush and Nikro contact-cleaning systems that navigate intact duct runs while our HEPA-filtered vacuums maintain negative pressure to prevent debris release into your home. Where we find disconnected or severely compromised sections, we’ll document the issue with our camera and discuss repair or replacement options with upfront pricing before any additional work. For a clear picture of what your specific system needs, schedule our $149 video inspection.
Yes, and this is one of the most common scenarios we encounter in East Palo Alto. We serviced a 1950s tract home on Gloria Way where the original galvanized trunk line was still connected to a modern air handler, packed with decades of debris and biological growth. Using our Rotobrush system, we extracted over 15 pounds of dust and mold, then sealed poorly spliced flex-duct joints to prevent recontamination from the marine air that seeps through crawlspaces. The new equipment had been recirculating that contamination since installation. Cleaning and sealing the legacy ductwork restored system efficiency and eliminated the musty odor the homeowner had assumed was normal for an old house. If your upgrade didn’t include duct replacement, camera inspection will reveal what your new system has been pushing through. Call (844) 685-6342 to schedule.
