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 Richmond, CA
Full-system air duct cleaning in Richmond typically runs $450 – $850 for a single-family home, with most jobs completed in one visit. Richmond’s industrial heritage and coastal climate create conditions we don’t see in nearby cities, from oily refinery residue in ducts to salt-fostered mold in older systems. We’re Hollis Air Duct Cleaning, and our crews work Richmond homes with equipment and methods matched to those realities. Call us at (361) 326-5060 for a written estimate before any work begins.
Why Richmond Homes Are Different
Richmond sits on the eastern shore of San Francisco Bay, where the marine layer pushes salt-laden moisture into crawl spaces and attics. That moisture, combined with decades of industrial emissions from the Chevron refinery and former shipyard operations, creates a distinctive contamination profile in local ductwork. In neighborhoods like Iron Triangle and Santa Fe, we regularly find black, oily residue coating duct interiors that standard brushes alone won’t remove.
The housing stock compounds the challenge. Point Richmond’s early 1900s Victorians often retain original galvanized ductwork or early flexible runs that trap particulate. Postwar tract homes in the Richmond Annex and nearby El Sobrante frequently have undersized returns and leaky joints that redistribute rather than remove debris. The Hayward Fault runs through the city, so post-earthquake duct inspections are a recurring need after seismic events. Richmond’s cool, foggy summers mean HVAC systems cycle less for temperature but more for air circulation, allowing dust and spores to accumulate without the flushing effect of constant heating or cooling.
Our Main Richmond Services
These are the three services Richmond homeowners call us about most often. Each has its own Richmond page with detailed pricing, process, and local conditions.
Air Duct Cleaning in Richmond
Our Air Duct Cleaning in Richmond covers the full supply and return network, from main trunk lines to individual branch ducts. In Richmond, we often start with specialized degreasing on refinery-affected systems before switching to rotary brush agitation and negative-air extraction. We run Nikro negative-air machines to maintain containment during the job, and we photograph the interior before and after so you see what came out. Post-remediation verification is available for homes with prior soot or heavy-metal contamination.
Duct Sealing in Richmond
Our Duct Sealing in Richmond targets the leaky joints and disconnected runs common in homes with original or aging flexible ductwork. We apply mastic sealant and mechanical fasteners at every joint, then pressure-test the system to confirm sealed performance. In Richmond’s climate, sealed ducts reduce the moisture infiltration that fosters mold and prevents your HVAC from circulating unfiltered garage or crawl-space air.

FAQs About Air Duct Cleaning Company in Richmond
Standard residential duct cleaning does not require a permit in Richmond. Duct sealing and return modifications may need a building permit if they alter the system’s design capacity; we handle permit research and include that detail in your written estimate if applicable. Call (361) 326-5060 and we’ll check your specific scope.
We prioritize post-earthquake duct inspections for Richmond customers who report visible damage, smell gas, or hear new HVAC noises after a seismic event. Our live answering takes calls 24 hours a day, and we schedule inspections as soon as the property is safe to enter. Call (361) 326-5060 to get on the list.
Most Richmond HOAs do not require approval for interior duct cleaning. Condo and townhouse associations in Marina Bay or similar developments may require notice for equipment access to shared mechanical rooms or exterior vents; we provide written work summaries on request. Call (361) 326-5060 and we’ll coordinate with your property manager if needed.
