Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Palo Alto’s mix of Eichler tract homes with radiant-floor heating and older Craftsman houses with retrofitted ductwork creates cleaning challenges that out-of-town crews often miss. Our technicians are trained on the specific layouts we find in neighborhoods from Greenmeadow to Old Palo Alto, and we dispatch from our San Francisco Bay Area office to keep arrival windows tight.
Why Palo Alto Homes Are Different
Palo Alto’s housing stock is unlike anywhere else in Santa Clara County. The Eichler neighborhoods, Greenmeadow and Fairmeadow included, were built with radiant floor heating and no central ductwork at all. When homeowners added cooling or wall furnaces later, the supply ducts they installed are often shallow, poorly sealed, and run through crawlspaces that collect dust and fiberglass particles. We regularly find that the few ducts present are pulling air from beneath the home rather than from conditioned space.
The older Craftsman and Spanish Revival homes north of University Avenue or in Professorville present the opposite problem: original ductwork from the 1920s to 1950s, retrofitted multiple times, usually leaky and undersized. Tight crawlspaces under these homes mean our Nikro negative-air machines and Rotobrush rotary systems need to be maneuvered carefully, sometimes in sections.
Climate plays a role too. Palo Alto’s mild summers and wet winters mean HVAC systems sit idle for long stretches. Dust, pollen from oak and redwood street trees, and moisture accumulate in ducts during these idle periods, then blow through the house when systems finally cycle on in spring. The pollen load here is heavier than in drier inland cities, and leaky ductwork pulls it in actively.
Our Main Palo Alto Services
These are the three services Palo Alto homeowners call us about most often. Each has its own page with detailed pricing, local conditions, and what to expect on the day of service.
Air Duct Cleaning in Palo Alto
We clean the full supply and return duct network with a Rotobrush rotary brush system and HEPA-filtered negative-air collection. In Palo Alto, this often means working around tight crawlspaces under Craftsman homes or cleaning the limited duct runs feeding add-on cooling in Eichler houses. We photograph the before and after condition inside your ducts so you see what was removed. Every job gets a written price upfront and our 365-Day Done Right Promise. Air Duct Cleaning in Palo Alto has full details on what’s included and how we handle local home types.

Dryer Vent Cleaning in Palo Alto
Lint buildup in dryer vents is a fire hazard, and in Palo Alto’s older homes the vent runs are often longer and more convoluted than modern code allows. We clean the full vent path from the back of the dryer to the exterior termination using rotary brushes and high-velocity air tools. If we find a damaged vent or improper routing, we note it in writing and explain your options before doing any additional work. Dryer Vent Cleaning in Palo Alto covers what we find in local homes and how we address it.

Duct Sealing in Palo Alto
Leaky ducts waste energy and pull in crawlspace air, pollen, and dust. In Palo Alto, we seal ductwork with mastic and metal tape, or apply aerosolized duct sealant for systems with access limitations. Eichler homes with add-on ducts and older Craftsman retrofits both benefit significantly, since the original installations were rarely sealed to modern standards. We test leakage before and after so you see the improvement in writing. Duct Sealing in Palo Alto explains the methods and typical results for local housing stock.
