Marin County's air ducts deal with more than ordinary dust. Redwood-shaded homes in Mill Valley and Sausalito stay damp for weeks after the coastal fog burns off, which gives mold and musty odors a real head start. Inland, San Rafael and San Anselmo swing between hot valley summers and cold winter nights, so HVAC systems there run harder and longer than most, pulling dust and pollen through the ductwork the whole time. We've worked on all of it, from century-old properties near downtown San Rafael to newer builds out in Novato.
Most calls fall into one of four categories: residential air duct cleaning, dryer vent cleaning, HVAC sanitizing and deodorizing, or commercial ventilation work. They often overlap on the same visit, since a house that needs its ducts cleared usually needs its dryer vent checked too. Here's what each one covers.

Most homes haven't had their ducts cleaned since the system went in. We run clean-capture vacuums and flexible brushes through the supply and return lines to pull out years of dust, dander, and debris.

If your clothes need two cycles to dry, the vent is blocked. Packed lint is a real fire hazard, and it's why your dryer runs twice as long as it should. We clear the full run out to the exterior hood.

A musty smell every time the system kicks on usually means something is growing inside the ductwork or on the coil. We treat the lines to handle the odor at the source instead of covering it up.

Offices, retail spaces, and small commercial buildings run their air systems harder than a house does, so they load up faster. We schedule the work around your hours.

Marin County housing runs from century-old Victorians in San Rafael to redwood-shaded homes in Mill Valley and newer builds in Novato. Vintage duct layouts, tight crawl spaces, and multi-story systems: we've worked on all of it.
Our technicians know the difference between a duct that needs a light pass and one that needs a full negative-pressure extraction. That only comes from doing this work repeatedly across the same neighborhoods, year after year.
You'll know the price before we start. Every job wraps up with the work area as clean as we found it, no dust trails, no surprise charges added after the fact.
