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 Vallejo, CA
Air duct cleaning in Vallejo typically costs $350 – $650 for a whole-home system, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and we’ve learned that Vallejo homes present a distinct set of challenges you won’t find in other Bay Area markets. Between the refinery corridor along I-80, the pre-1978 housing stock with original galvanized ductwork, and the dry-hill dust that gets pulled into systems running year-round, duct cleaning here is less about maintenance and more about removing what’s actually accumulating. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Vallejo Homes Are Different
Vallejo sits at the northeast corner of San Francisco Bay, directly in the path of two major refineries and one of the busiest freight corridors in California. The fine soot and diesel particulate that settles over the city doesn’t stay outside. It gets drawn through HVAC intakes, and over months it coats duct walls with a film that standard household filters won’t catch. After a Spare the Air day or refinery flaring event, we field calls from older west-side neighborhoods where homeowners can smell the difference indoors. Our crews regularly find ducts coated with a thin, oily black residue that requires rotary brush agitation and negative-air extraction to remove properly.
The housing stock compounds the problem. Much of Vallejo was built before 1978, and many of those homes still run on original galvanized steel ductwork that has never been cleaned. In Northgate and Hiddenbrooke, the 1980s and 1990s tract homes shifted to flexible ducting, which can sag, tear, and harbor dust and pests in ways rigid metal won’t. The climate doesn’t offer a break either. Mild, wet winters and hot, dry summers mean systems run continuously, pulling in dust from the surrounding hills and refinery-adjacent air. Ducts here accumulate debris faster than in more temperate Bay Area microclimates.
Our Main Vallejo Services
Vallejo homeowners call us most often for three jobs. Each has its own page with full details, pricing, and what to expect.
Air Duct Cleaning in Vallejo
We clean the full supply and return duct network using Rotobrush rotary brush systems and Nikro negative-air machines. In Vallejo, this means addressing the oily particulate film that refinery corridor homes collect, not just household dust. We agitate the duct walls, extract debris under controlled negative pressure, and show you before-and-after photos of your own system. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Vallejo
Dryer Vent Cleaning in Vallejo
Lint buildup in dryer vents is a fire hazard, and Vallejo’s older homes often have long vent runs through walls or attics that are hard to access and rarely maintained. We clear the full line from dryer to termination, check airflow with a meter, and verify the exterior damper operates freely. If the vent run is damaged or improperly routed, we’ll note it in writing. Dryer Vent Cleaning in Vallejo
Duct Sealing in Vallejo
Leaky ducts waste conditioned air and pull in attic or crawl space contaminants. In Vallejo’s pre-1978 homes with aging galvanized steel, joints and seams separate over decades of thermal cycling. We seal accessible ductwork with mastic and mechanical fasteners, then pressure-test to verify results. For flexible duct systems in newer tracts, we inspect for kinks, tears, and collapsed sections that restrict airflow. Duct Sealing in Vallejo

FAQs About Air Duct Cleaning Company in Vallejo
Yes, typically every 3 – 5 years rather than the 5 – 7 year standard for cleaner airsheds. The refinery corridor and I-80 freight traffic introduce particulate loads that Napa or Fairfield simply don’t experience at the same concentration. After visible flaring events or heavy Spare the Air periods, we recommend inspection even if you’re inside that window. Call (361) 326-5060 to schedule.
Standard residential duct cleaning requires no permit in Vallejo. Duct sealing that involves access to shared mechanical spaces in condos or townhomes may need HOA notification, which we handle by documenting our scope in writing before work begins. We do not perform work that triggers building permit requirements without flagging it in your upfront quote.
We photograph the interior of your ducts before and after cleaning, and we show you the images on-site. For sealing jobs, we pressure-test the system and record the results. Every Hollis job includes written documentation of what was performed, what was found, and what the 365-Day Done Right Promise covers. No verbal reports, no hand-waving.
