Air Duct Cleaning in Palo Alto - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Palo Alto

Air duct cleaning in Palo Alto typically runs $350 – $750 for a residential system and $800 – $2,500 for commercial work, with most jobs scheduled within a few days and completed in a single visit. We dispatch crews from our San Francisco Bay Area office and serve Palo Alto directly, which means we’re familiar with the crawlspaces, slab foundations, and retrofit ductwork that define this city’s housing stock.

Call (361) 326-5060

We’ve been cleaning ducts in Palo Alto since 2004 as part of the Garrison Partners family, and we’ve learned that homes here aren’t like homes in neighboring cities. Eichler neighborhoods like Greenmeadow have radiant heating in concrete slabs with little to no central ductwork. Older Craftsman and Spanish Revival houses along Waverley Street and Kingsley Avenue carry original duct runs from mid-century retrofits, often leaky, undersized, and buried in tight crawlspaces. A crew that doesn’t know what to look for will clean what’s easy to reach and miss what’s actually blowing dust into your living room.

Our Air Duct Cleaning team runs camera inspections before any agitation work begins. We price the job in writing before we start, and every residential and commercial clean is covered by our 365-Day Done Right Promise. If you’re seeing dust buildup, smelling musty air when the system kicks on, or noticing your HVAC struggling to move air through undersized runs, call us at (361) 326-5060. We’ll give you a free estimate with an actual price, not a teaser that doubles at the door.

Why Hollis Air Duct Cleaning Is Palo Alto’s Preferred Air Duct Cleaning Company

We’ve built our reputation in Palo Alto on showing up inside the window we quoted, pricing in writing before touching equipment, and leaving the site clean. That’s The Garrison Standard, and it applies to every job we run in Santa Clara County.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops or callback queues. When you call (361) 326-5060, you talk to a human who can schedule your Palo Alto appointment and answer questions about what we’ll actually find in your ductwork.

We carry professional-grade equipment: Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use in hospitals and schools, not hardware-store vacuums with a brush attachment.

Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.

Residential Air Duct Cleaning in Palo Alto

Residential Air Duct Cleaning in Palo Alto means working with homes that were never designed for central forced air. Eichler tract houses in Greenmeadow and Fairmeadow were built with radiant heating pipes encased in concrete slabs. Any ductwork you find is an add-on, feeding wall furnaces or evaporative coolers through short, often poorly sealed supply runs. Older homes south of University Avenue or along Middlefield Road carry retrofitted ductwork from the 1960s and 70s, original sheet metal with taped joints that have dried and failed over decades.

A typical residential duct cleaning in Palo Alto runs $350 – $750 for a full system with camera inspection, agitation, and negative-air extraction. If we find disconnected or crushed runs that need reconnection and sealing, that work is priced separately and agreed in writing before we proceed. We don’t quote per-vent teaser prices that balloon once we’re inside.

Camera Inspection and Source Removal

We run a video scope through every accessible run before any cleaning starts. In Palo Alto’s tight crawlspaces, we regularly find original ducts crushed by settling, joints separated above the slab, or fiberglass flex duct degraded to the point it’s shedding particles into the airflow. Source removal means we extract what’s loose and accumulated, not just blow it around with a shop vacuum.

Sealing and Reconnection Work

Cleaning alone won’t fix a disconnected duct. When our camera finds a joint pulling crawlspace dust directly into your living room, we reseal with mastic and mechanical fasteners, then test airflow before we leave. The sealing work is often the real fix in Palo Alto homes, and we price it upfront, not as a surprise add-on.

Commercial Air Duct Cleaning in Palo Alto

Commercial Air Duct Cleaning in Palo Alto covers office buildings along El Camino Real, medical suites near Stanford, retail spaces in Town & Country Village, and multi-tenant properties throughout the 94301, 94303, and 94306 zip codes. Commercial systems run harder and longer than residential units, and they accumulate construction dust, paper fiber, and biological loading that residential crews aren’t equipped to handle.

Commercial duct cleaning in Palo Alto typically ranges from $800 – $2,500 depending on system size, access difficulty, and contamination level. We price by the system, not by the vent count, and we provide a written scope of work before any equipment enters your building. Our Nikro negative-air machines maintain containment during cleaning, and we schedule around your hours to minimize disruption to tenants or patients.

Containment and Disruption Control

Commercial spaces can’t tolerate dust migration into occupied areas. Our negative-air method establishes a controlled pressure differential that pulls debris toward our collection unit, not into your workspace. We seal registers, protect floors, and coordinate with building management to isolate zones during work.

Post-Clean Verification

After agitation and extraction, we run a second camera pass to document condition. Building managers in Palo Alto receive before-and-after footage of their own ducts, not stock photos from another job. If the work doesn’t meet the scope we agreed to, our 365-Day Done Right Promise covers a return visit at no charge.

Trusted Brands We Service in Palo Alto

We stock filters, media, and replacement components from Honeywell, Aprilaire, and Abatement Technologies for Palo Alto customers, which means faster turnaround when your system needs more than cleaning. Honeywell media filters handle the pollen load that hits Palo Alto hard in spring, when oak and redwood pollen infiltrates leaky ductwork during long idle periods. Aprilaire whole-house filtration integrates with retrofitted systems common in older Palo Alto homes. Abatement Technologies HEPA filtration protects indoor air quality during the cleaning process itself. We don’t sell you equipment you don’t need, and we explain what each component does for the air moving through your specific system.

Common Air Duct Cleaning Problems We See in Palo Alto Homes

• Eichler radiant-floor layouts confuse out-of-town crews. Technicians unfamiliar with Palo Alto’s mid-century tracts search for a central air handler that doesn’t exist, miss the short add-on ducts feeding wall furnaces entirely, and leave the actual dust source untouched. We map every run before we start.
• Retrofitted ductwork in Craftsman and Spanish Revival homes pulls crawlspace debris. Original sheet-metal runs with failed tape joints draw fiberglass particles and dust through disconnected seams, especially during Palo Alto’s long idle periods between heating seasons when negative pressure differential is highest.
• Crushed or disconnected runs in tight crawlspaces redistribute dust instead of removing it. A standard surface clean without camera inspection blows debris loose but can’t extract it through a collapsed or blocked duct. We find and fix the obstruction first.
• Spring pollen accumulation in undersized systems. Palo Alto’s abundant street trees load outdoor air with oak and redwood pollen that infiltrates leaky ductwork during mild spring weather, when homeowners aren’t running heat or cooling and don’t notice the buildup until summer kicks on.
