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.

AfterAir Duct Cleaning Company in North Fair Oaks, CA
Air duct cleaning in North Fair Oaks runs $350 – $650 for a typical single-family system, with most jobs completed in one visit. What drives the real cost isn’t the square footage on paper; it’s the 1940s – 1960s ranch housing stock, the DIY subdivisions, and the fog-belt moisture that turns galvanized steel ducts into rusted, musty passages no homeowner should breathe. We dispatch crews from our San Francisco Bay Area office to serve North Fair Oaks directly. Call (361) 326-5060 for a written estimate before any work starts.
Why North Fair Oaks Homes Are Different
North Fair Oaks sits in the San Francisco Peninsula’s fog belt, where cool, damp summers and mild winters mean HVAC systems run less for heating or cooling and more for air circulation. That stagnant, humid air inside original galvanized steel ductwork creates a problem you won’t find in hotter inland markets: condensation that never fully dries, rust flaking into supply vents, and mold colonizing poorly insulated attic runs. We’ve opened ducts in North Fair Oaks that looked clean to the eye but tested positive for moisture-loving contaminants.
The housing stock compounds this. Most homes are 1940s – 1960s single-story ranches on small lots, many still carrying original ductwork in shallow attics. A significant number have been subdivided into two or more units, often with DIY flex-duct additions crammed into shared plenums, separate HVAC systems fighting for space, and illegal unpermitted modifications that violate San Mateo County code. We regularly encounter jobs where a landlord needs documentation for county compliance, or where a multi-generational family has inherited a patchwork system with no original drawings.
After the rainy season ends in March, our techs find flooded 1950s furnace closets in crawlspaces throughout the neighborhood. Soaked duct insulation doesn’t dry in this climate; it breeds odor that residents mistake for “old house smell.” Sometimes cleaning isn’t enough, and we’ll say so upfront rather than sell a service that won’t solve the problem.
Our Main North Fair Oaks Services
North Fair Oaks homeowners call us for three jobs, each with its own local conditions and pricing. Every visit follows The Garrison Standard: arrive inside the window, price in writing, work by the book, leave the site clean.
Air Duct Cleaning in North Fair Oaks
Our Air Duct Cleaning in North Fair Oaks uses Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract buildup from original galvanized steel and retrofitted flex duct alike. In this market, we often find illegal multi-unit modifications that have created cross-contamination between dwellings. We document what we see, clean what can be cleaned safely, and flag code violations that need correction before the next tenant moves in.
Dryer Vent Cleaning in North Fair Oaks
Our Dryer Vent Cleaning in North Fair Oaks addresses a fire risk that multiplies in subdivided homes, where one laundry room may serve two or three units through extended, often kinked vent runs. The fog-belt humidity here causes lint to cake and adhere rather than blow through. We clear the full run with professional-grade tools, measure airflow before and after, and provide written documentation for landlords and property managers.
Duct Sealing in North Fair Oaks
Our Duct Sealing in North Fair Oaks targets the leakage points created by decades of amateur modifications: disconnected flex joints, gaps at plenum connections, and rust-through in original steel. We apply mastic sealant and mechanical fasteners where appropriate, using Abatement Technologies testing equipment to verify reduced leakage. In shared-attic subdivisions, sealing one unit’s ducts often improves performance for neighbors too.
