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.

AfterFast, Reliable Air Duct Cleaning Across Rodeo
Air duct cleaning in Rodeo, CA typically costs $350 – $750 for a full residential system and is scheduled within a few business days, with our crew dispatching from the San Francisco Bay Area office to serve Rodeo directly. We’re familiar with the specific conditions here: the slick, dark film that coats ductwork in homes downwind of the refineries, the corroded sheet-metal runs in mid-century worker housing, and the way San Pablo Bay fog traps petrochemical particulate inside your system. When you call Hollis Air Duct Cleaning at (361) 326-5060, you’ll speak to a live person who understands Rodeo’s geography and can schedule your free estimate without putting you in a callback queue.
Our technicians have worked on California Street homes near the waterfront, in the hills above Rodeo Creek, and throughout the neighborhoods between Interstate 80 and San Pablo Avenue. We’ve cleaned ducts in the original refinery housing with unsealed joints and no filtration, and we’ve restored systems in newer builds where the same airborne residue still finds its way inside. Roy Castellanos and our team treat every Rodeo job under The Garrison Standard: arrive inside the quoted window, price in writing before touching anything, and leave the site clean.
Why Hollis Air Duct Cleaning Is Rodeo’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Rodeo by addressing a problem most duct cleaners in Hercules or Pinole never encounter: refinery particulate that demands contact cleaning with degreasers, not standard brushing. Our Air Duct Cleaning team arrives with Nikro negative-air machines and Rotobrush rotary systems, but we also carry the specialized cleaning agents required for the oily residue unique to this area.
Rodeo homeowners tell us they chose Hollis because we explain what we’re seeing before we quote. That dark film in your ducts? We show you. The corroded joint leaking into your crawl space? We photograph it. Our background-checked, uniformed technicians follow The Garrison Code on every job: accountable, verifiable, and squared away. Calls are answered by a live person 24 hours a day, 7 days a week, and every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.
We don’t compete on teaser prices. We compete on the price you can trust: written down before work starts, with no surprises when the technician is already in your home.
Air Duct Repair in Rodeo
Air Duct Repair in Rodeo often involves fixing corroded sheet-metal runs and resealing joints that have leaked for decades in the original refinery worker housing. The humid, salt-laden air from San Pablo Bay accelerates rust in unlined ducts, and once corrosion opens a gap, conditioned air escapes into attics and crawl spaces while the same refinery particulate you’re trying to filter out gets drawn back into your living space. A typical repair in Rodeo runs $200 – $500 for joint sealing and patching, or $800 – $1,400 for replacing a corroded section with new ductwork.
Corrosion Damage from Bay Air
We find this most often in homes west of California Street, where morning fog rolls in from San Pablo Bay and moisture combines with salt to eat through galvanized steel. Our technicians cut out the damaged section, fabricate a replacement from matching gauge metal, and seal with mastic rated for your system’s temperature range. We also inspect upstream to find where moisture is entering, because patching one hole without fixing the source means you’ll call us again in two years.
Resealing Original Refinery-Era Joints
Mid-century ducts in Rodeo were often assembled with snap-lock seams and no sealant. We disassemble accessible runs, apply duct sealing mastic to every joint, and reconnect with mechanical fasteners. For systems with widespread leakage, we may recommend Duct Sealing in Rodeo using aerosolized sealant that reaches leaks we can’t physically access.
Ductwork Cleaning in Rodeo
Ductwork Cleaning in Rodeo requires more than the standard rotary brush pass that might suffice inland. The fine oily particulate from refinery emissions bonds to duct walls, especially where moisture from bay fog has created a sticky surface. Standard brushing can smear this film rather than remove it. Our process uses contact cleaning with professional degreasers, followed by negative-air extraction with Nikro equipment, to actually lift the residue out of your system rather than redistribute it. A typical residential ductwork cleaning in Rodeo runs $350 – $650 for a single system, or $550 – $750 if we include the return plenum and air handler cabinet.
Supply Duct Cleaning
Supply ducts carry conditioned air to your rooms, but in Rodeo they also carry whatever accumulated in your system through the off-season. We clean each supply branch from the trunk to the register, using Rotobrush rotary systems with HEPA containment so the particulate we dislodge doesn’t enter your home. For homes near the refinery corridor, we often find registers clogged with a greasy dust that standard vacuums won’t touch.
Return Duct Cleaning
Return ducts pull air back to your handler, and in Rodeo they’re the entry point for refinery particulate. We inspect the return plenum with a video camera, then clean the full return path including the filter rack. If your system lacks proper filtration, we’ll note it in our written report and can install upgraded media filters from Honeywell or Aprilaire sized to catch the fine particles common here.
Trusted Brands We Service in Rodeo
We stock parts and filtration products from Honeywell, Aprilaire, and Abatement Technologies for Rodeo customers, which means most repairs don’t wait on shipping. Our equipment roster includes Rotobrush rotary brush systems for mechanical cleaning, Nikro negative-air machines for contained extraction, and Guardsman filtration products for upgraded protection. When we recommend a filter upgrade for your Rodeo home, we’re specifying media that can handle the fine particulate load this area generates, not just standard household dust. We also handle Dryer Vent Cleaning in Rodeo using the same professional-grade tools and the same written pricing standard.
Common Air Duct Cleaning Problems We See in Rodeo Homes
- Dark, greasy film in ducts near the refinery corridor. This isn’t ordinary dust. It’s oily particulate that settles in supply and return runs, reduces airflow, and can carry odor into living spaces. Standard brushing won’t remove it; we use contact cleaning with degreasers and handle the waste as potentially contaminated.
- Corroded sheet-metal ducts in mid-century homes. Built as worker housing with minimal investment in longevity, these systems often have unlined galvanized steel that’s rusted through after sixty years of bay air exposure. We repair where possible and replace where necessary, always with written pricing first.
- Unsealed joints pulling in garage or crawl space air. Original refinery-era ductwork was assembled without mastic or tape. In Rodeo’s older homes, we regularly find return leaks drawing air from musty crawl spaces or attached garages, bypassing filtration entirely and pressurizing the system with contaminants.
- Moisture accumulation from fog and poor insulation. San Pablo Bay fog introduces humidity that condenses in uninsulated duct runs, especially in hillside homes above Rodeo Creek. Wet ducts grow microbial contamination and accelerate corrosion; we identify the moisture source and recommend insulation or sealing as part of our written report.
Pricing for Air Duct Cleaning in Rodeo, CA
Most full residential air duct cleaning jobs in Rodeo fall between $350 and $750, depending on system size, accessibility, and the severity of refinery residue buildup. A basic single-system cleaning with standard dust and debris removal starts around $350. Systems with heavy oily particulate requiring degreaser contact cleaning and extended extraction time run $550 – $750. Commercial systems or multi-zone residential setups range from $800 – $1,500. We also offer video inspection as a standalone service for $150 – $250, or included with full cleaning.
What affects your price: the number of supply and return vents, whether your ducts are accessible through existing registers or require crawl space entry, the presence of corrosion or damage needing repair, and whether we need to handle waste as contaminated material. We give one flat price per system, agreed in writing before work starts. No per-vent add-ons. No equipment charges that appear after we’re in your home. Call (361) 326-5060 for a free estimate, and we’ll quote your specific Rodeo home with no obligation.

Low teaser quotes usually become larger invoices once the technician is inside your home. Some outfits quote a per-vent rate that doubles or triples by the door. Others use shop vacuums instead of contained negative-air systems, which redistributes dust through your house. Hollis gives one flat price per system in writing before work starts, using professional equipment from Rotobrush and Nikro. The price doesn’t move at the door.
Every Hollis job is backed by our 365-Day Done Right Promise in writing. If the cleaning fails to resolve the issue we were hired to address, or if workmanship defects appear within one year, we return and make it right at no charge. This includes a free second visit if needed. The guarantee is not prorated, not limited to “material defects,” and not subject to negotiation when you call.
