Why East Palo Alto Homes Are Different

East Palo Alto sits directly downwind of the Ravenswood Slough and San Francisco Bay tidal flats. Prevailing westerly winds push fine dried sediment, marsh allergens, and salt-laden air into outdoor intakes at rates far higher than in neighboring Palo Alto or Menlo Park. The marine layer raises overnight humidity inside older uninsulated metal ductwork, encouraging mold and dust-mite colonization uncommon in drier Valley cities. Most homes here are post-WWII tract construction from the late 1940s through 1970s, many with informal additions or garage conversions that produced poorly sealed flex-duct connections bypassing filters and collecting debris faster than original systems ever did.

Air Duct Cleaning in East Palo Alto

Our Air Duct Cleaning crews in East Palo Alto start every job with a camera inspection because original ductwork here is often too fragile to clean blindly. The combination of age, bay air moisture cycling, and decades of airflow pressure causes 1970s-era spiral foil flex to collapse or tear at bends, especially in homes with garage conversions or informal additions where duct sizing was never recalculated.

Residential Duct Cleaning

Most East Palo Alto homes we service are single-family tracts with original ductwork, many now long-term rentals never professionally serviced. We clean supply and return runs, registers, and the main trunk line using Rotobrush equipment, paying special attention to salt residue buildup on metal surfaces near the bay. A typical residential duct cleaning runs $280-$450 for a standard single-system home with 8-12 vents. Full system cleaning with video inspection, including supply and return runs, trunk line, and air handler, typically ranges $380-$580.

Commercial Duct Cleaning

East Palo Alto’s commercial buildings along University Avenue and near the bay face sediment loads multiplied by rooftop HVAC intakes with less frequent filter changes. We scale our Nikro and Abatement Technologies equipment to the job, with upfront pricing disclosed before a single tool is lifted. Commercial duct cleaning starts around $450 and scales with square footage and system complexity.

Why does my 1950s East Palo Alto home need a video inspection before duct cleaning?

Original ductwork from this era is often fragile, and we need to verify that runs are intact before running cleaning equipment through them. In East Palo Alto specifically, we’ve found separated spiral foil flex and collapsed bends hidden inside walls that would have been destroyed by brushes passing blindly. The inspection takes ten minutes and gives you a permanent record of your system’s condition. Call (855) 401-6006 to schedule.

Dryer Vent Cleaning in East Palo Alto

Dryer vent cleaning in East Palo Alto typically runs $180-$340, with most jobs completed in one visit. Salt-laden bay air destroys standard galvanized vent caps in 5-7 years instead of the 12-15 typical inland, and decades of deferred maintenance in rental units leave original flex ducts with collapsed bends that block airflow and create fire risk. Our Dryer Vent Cleaning starts with a camera inspection every time.

Vent Cleaning & Lint Removal

We use Rotobrush and Nikro equipment to agitate and extract lint from the full vent run, including the transition duct behind your dryer and the exterior termination. East Palo Alto’s coastal humidity means lint clumps and adheres to duct walls more stubbornly than in drier climates. We verify with a post-cleaning camera pass. A standard single-story home with a straight vent run under 15 feet runs $180-$240; two-story homes, roof terminations, or vents with multiple bends typically fall in the $260-$340 range.

Vent Rerouting

Many East Palo Alto homes have dryer vents rerouted during informal garage conversions using improper materials or excessive bends. We find flex duct crushed behind studs and runs terminating in crawl spaces instead of outside. Rerouting to code-compliant rigid metal duct with proper slope and exterior termination typically runs $320-$480.

How often should I get my dryer vent cleaned in East Palo Alto?

For most East Palo Alto homes, we recommend annual cleaning given the coastal humidity and older housing stock. Homes with long vent runs, multiple bends, or heavy laundry usage may need service every 6-9 months. If your dryer takes more than one cycle to dry a standard load, or if you smell burning near the laundry area, call immediately. Call (855) 401-6006 for an exact quote.

HVAC Cleaning in East Palo Alto

HVAC cleaning in East Palo Alto typically runs $280-$650 for a full system, with most jobs completed in a single visit. Bay sediment, salt, and marsh allergens bypass compromised filters in older ductwork and pack onto coils and blower components, cutting airflow and forcing compressors to run longer. Our HVAC Cleaning addresses each component with equipment matched to the contamination load.

Evaporator Coil Cleaning

The evaporator coil is where East Palo Alto’s unique contamination pattern does its worst damage. In this city’s humid marine-layer conditions, 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 fins on older systems. A typical evaporator coil cleaning runs $180-$340.

Blower & Condenser Cleaning

The blower wheel collects everything the filter misses, and in homes with original or poorly sealed ductwork, that’s substantial. We remove the blower assembly when accessible, clean the wheel vanes and housing, and balance it before reinstallation. Most blower cleanings fall between $160-$290. Outdoor condenser coils face salt coating and marsh vegetation clogging; cleaning runs $140-$260, especially important for homes near the Bayfront Expressway or eastern edge by Ravenswood Slough.

My 1960s home has original flex ducts that look crushed in spots. Can you still clean them?

We can clean them only after we repair them. Crushed or separated flex duct blocks our cleaning equipment and would 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. We reseal or replace damaged sections before proceeding with cleaning. Call (855) 401-6006 to schedule an inspection.

Duct Repair & Sealing in East Palo Alto

Duct repair and sealing in East Palo Alto typically costs between $280 and $650 for most residential jobs. The salt-laden westerly winds off the Bay accelerate corrosion at joints and seams, while collapsed 1970s flex duct and unsealed connections from informal additions waste energy and pull in unfiltered air. Our Duct Repair & Sealing crews camera-inspect first, then quote transparently.

Flex Duct Repair

Flex duct repair is our most common call here. Where the duct is structurally sound, we reconnect and reinforce with mastic and stainless steel band clamps, then test for airflow and leakage. Flex duct repair for a single run typically runs $180-$320. Full replacement becomes necessary when multiple sections are collapsed, torn, or inaccessible behind finished walls.

Duct Sealing with Mastic

In homes built from the late 1940s through the 1970s, original duct tape has long since dried and cracked, especially in attics and crawl spaces where bay moisture cycles through daily. We seal joints, connections, and penetrations with professional-grade mastic that flexes with temperature changes and won’t degrade like tape. Mastic sealing of a full duct system typically runs $380-$650.

Can you repair the original 1970s flex duct in my East Palo Alto home, or does it need full replacement?

We can often repair original 1970s flex duct if the wire helix is still structurally intact and the foil liner hasn’t degraded to tearing. Where connections have separated or short sections have collapsed, we reconnect with mastic and stainless steel band clamps, then reinforce and insulate. Full replacement becomes necessary when the duct is extensively degraded or inaccessible. Call (855) 401-6006 for a camera inspection and exact quote.

Air Quality & Sanitizing in East Palo Alto

Air quality and sanitizing service in East Palo Alto typically runs $280-$650 for whole-home treatment, with most appointments completed in a single visit. The marine layer pushes overnight humidity into uninsulated metal ducts, and salt-laden air corrodes interiors, creating conditions where mold colonizes in 24-48 hours. Our Air Quality & Sanitizing services address the source, not the symptom.

Mold Treatment

Mold in East Palo Alto ductwork is not a question of if but where. We perform full Rotobrush cleaning followed by antimicrobial application, with camera verification. Mold treatment for a single zone runs $340-$580; whole-home treatment ranges $520-$780 depending on system size and contamination depth.

Bacteria Sanitizing & Odor Removal

Bacterial loads spike in homes with collapsed or separated flex duct, because gaps pull in unfiltered air from crawl spaces carrying organic matter from Ravenswood Slough. We fog EPA-registered sanitizer through the entire duct network. Most bacteria sanitizing jobs fall between $280-$450. The sour, brackish smell homeowners describe as “like low tide in the vents” requires source elimination and antimicrobial application; odor removal ranges $320-$560.

Does the marine layer cause mold in ducts even if I run my AC?

Yes, because the marine layer raises humidity in uninsulated metal ducts during overnight hours when your AC is cycled off. Mold needs 24-48 hours of surface moisture to colonize, and East Palo Alto’s bay-proximity climate provides that several nights per week even in dry summers. Running the fan continuously helps, but sealing or insulating the ductwork, or installing a UV lamp, breaks the cycle. Call (855) 401-6006 for a free assessment.
