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 San Rafael, CA
Air duct cleaning in San Rafael runs $350 – $650 for a typical single-system home, with most jobs completed in one visit. What drives the price isn’t just square footage; it’s whether we’re working around original redwood framing in a 1920s West End Victorian or pulling decades of compacted dust from the long flexible duct runs of a Terra Linda Eichler. Crews are dispatched from our San Francisco Bay Area office and serve San Rafael neighborhoods directly. Call (361) 326-5060 for a written estimate before any work starts.
Why San Rafael Homes Are Different
San Rafael’s housing stock splits sharply between eras, and that split changes how we approach every job. In the West End and downtown, we regularly work in century-old Victorians and Craftsman homes with original redwood framing and ductwork that may have been added decades after the walls went up. Those systems need careful hand-cleaning around brittle materials and tight chases. Cross town to Terra Linda or Mont Marin and the story flips: mid-century Eichler-style and ranch tract homes built in the 1960s and 70s with long, flexible duct runs that sag, collect debris, and harbor roof rats from the nearby open space corridors.
Marin County’s mild, wet winters and dry summers mean HVAC systems here run less than inland, so ducts accumulate dust, pollen, and rodent debris rather than heavy condensation. Homes near Dominican University and the open-space corridors are especially prone to rodent intrusion through original foundation and attic vents that were never sealed. We carry mastic and metal flashing to close those entry points when we find them.
Our Main San Rafael Services
San Rafael homeowners call us most often for three jobs, each with its own page and pricing.
Air Duct Cleaning in San Rafael
We clean supply and return ducts with a Rotobrush rotary brush system or Nikro negative-air machine, depending on duct material and contamination level. In San Rafael’s older homes, we often find decades of compacted dust, pollen from the bay winds, and rodent nests near attic penetrations. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in San Rafael
Dryer Vent Cleaning in San Rafael
Dryer vent blockages are a leading cause of house fires, and San Rafael’s older homes often have vents routed through multiple stories of original framing or terminating in inaccessible soffits. We clear the full run with rotary brushes and airflow meters, then verify exhaust volume at the exterior cap. If the vent needs rerouting to meet current code, we price that in writing before touching anything. Dryer Vent Cleaning in San Rafael
Duct Sealing in San Rafael
Leaky ducts waste heated and cooled air into attics and crawl spaces, and in San Rafael’s Eichler-style homes with long flexible runs, the seams and sag points are often the worst offenders. We seal accessible joints with mastic and mechanical fasteners, then pressure-test the system to verify improvement. Duct sealing is frequently the most cost-effective upgrade for homes with high utility bills and rooms that never reach temperature. Duct Sealing in San Rafael
