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.
Fast, Reliable Air Duct Cleaning Across Rohnert Park
Air duct cleaning in Rohnert Park typically runs $350 – $650 for a full residential system and is usually completed in one scheduled visit. Most homeowners in the original ‘A’ through ‘L’ sections and newer golf-course neighborhoods call us after wildfire season or when they notice dust and pollen pushing through registers that never quite cleared.
We’ve worked in Rohnert Park long enough to know what these houses are built like. The slab-on-grade ranches and two-story stuccos from the 1960s through the 1990s dominate every neighborhood from the original tracts off Enterprise Drive to the developments near Foxtail Golf Club and The Links at Bodega Harbour. That means galvanized trunk lines, early flexible branch runs, and attic spaces tight enough that you can’t stand upright. Our crews carry the right equipment for those conditions: Rotobrush rotary systems for agitation, Nikro negative-air machines for source removal, and inspection cameras that let the homeowner see what we see before we quote anything.
Calls are answered by a live person, 24 hours a day, 7 days a week. Scheduling is coordinated from our San Francisco Bay Area office, with crews dispatched to Rohnert Park locally. When you call (361) 326-5060, you’ll speak to someone who can book your free estimate and explain what the visit covers.
Why Hollis Air Duct Cleaning Is Rohnert Park’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our standard hasn’t changed: written price before work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise on every job. If the work fails within a year, we come back and make it right at no charge, including a free second visit.
Rohnert Park homeowners know the difference between a crew that shows up prepared and one that improvises at the door. Our technicians arrive inside the quoted window, price the job in writing before touching equipment, and leave the site clean. That’s The Garrison Standard, and it’s how every Hollis location operates, independently owned and operated.
We don’t compete on teaser prices or per-vent coupons. We compete on the bid you can trust: one flat price per system, agreed before work starts, with before-and-after photos of your own ducts so you know the job was done.
Vent Cleaning in Rohnert Park
Vent cleaning in Rohnert Park means removing the buildup that collects at every supply and return register in homes where the HVAC system has been running through decades of oak pollen, wildfire smoke, and ordinary household dust. In the tract homes off Southwest Boulevard and near the Sonoma State University edge of town, we regularly find registers choked with fine particulate that standard filters never caught. A typical vent cleaning as part of a full system service in Rohnert Park runs $350 – $650; standalone vent cleaning for a limited scope starts around $180 – $280.
Supply Register Cleaning
Supply registers push conditioned air into your rooms. When they’re coated with dust and smoke residue, you’re breathing whatever shakes loose. We remove each register, clean the boot and first few feet of duct behind it, and reinstall everything properly sealed.
Return Vent Deep Cleaning
Return vents pull air back to the handler, so they act like a vacuum inlet for everything floating in your home. In Rohnert Park’s older tracts, these are often oversized wall or ceiling cavities that haven’t been opened in twenty years. We clean the full cavity, not just the grille.
Air Duct Repair in Rohnert Park
Air Duct Repair in Rohnert Park is often the real work hidden inside what homeowners call “duct cleaning.” The city’s housing stock, nearly all 1960s-1990s slab-on-grade construction with original ductwork now 30-50 years old, produces predictable failures: collapsed flex runs, separated collars, and galvanized trunk seams that leak conditioned air into uninsulated attics. A typical repair in Rohnert Park, from collar resealing to flex run replacement, runs $200 – $550 depending on attic accessibility and material length. Full trunk line replacement on an older system can reach $1,200 – $2,400.
Collapsed Flex Run Replacement
The original flexible branch runs in Rohnert Park’s ‘A’-‘L’ sections are brittle by now. We find them crushed under joists, pulled loose at takeoff collars, or split at the bend. We replace with new insulated flex, secure with proper straps and mastic, and pressure-check the connection.
Galvanized Trunk Sealing
Metal trunk lines expand and contract with every heating cycle. After forty years, the seams leak at every joint. We seal with duct mastic, not tape, because mastic remains flexible and won’t dry out in a Rohnert Park attic that hits 140°F in summer.
Trusted Brands We Service in Rohnert Park
Our equipment comes from manufacturers that commercial crews rely on: Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell and Aprilaire for homeowners who want to upgrade while we’re already in the system. We don’t show up with hardware-store vacuums and extension wands. The tools matter because Rohnert Park’s older ductwork is fragile; aggressive or improper equipment can damage galvanized seams or tear aging flex. We stock common repair parts locally, so when we find a disconnected collar or collapsed run during your cleaning, we can often fix it same visit rather than rescheduling.
Common Air Duct Cleaning Problems We See in Rohnert Park Homes
- Collapsed 1970s-80s flex branch runs in tight attics. In the original ‘A’ through ‘L’ sections off Enterprise Drive, our techs regularly find flex runs that have pulled loose at the collar or been crushed flat under a roof joist. The system pulls hot attic air instead of conditioned air, and the homeowner notices it as weak airflow and rising energy bills.
- Brittle galvanized trunk seams leaking at every joint. After 30-50 years of slab-on-grade heat cycling, the original metal trunk lines in Rohnert Park’s ranches shed rust and leak conditioned air into uninsulated attic spaces. We seal with mastic and replace sections where corrosion has penetrated.
- Wildfire smoke and oak pollen loaded into attic duct runs. Rohnert Park’s inland Petaluma Valley location traps smoke longer than coastal Sonoma towns, especially near the two golf courses and along the Laguna de Santa Rosa corridor. Older duct systems act as particle sinks, releasing trapped contaminants every time the blower cycles.
- Disconnected takeoff collars pulling attic air into bedrooms. The back bedrooms in single-story ranches are often the last on the line, and when the flex run separates at the collar, those rooms get stuffy and dusty while the attic gets cooled. Camera inspection finds it; resealing and replacement fixes it.
Pricing for Air Duct Cleaning in Rohnert Park, CA
A full residential air duct cleaning in Rohnert Park typically runs $350 – $650 for a single-system home, with most jobs falling in the $400 – $550 range. Commercial systems start around $800 and scale with square footage and access complexity. What moves the price: the number of supply and return vents, whether we find collapsed or disconnected runs that need repair, attic accessibility, and whether you add dryer vent cleaning or filtration upgrades.
We do not quote per-vent prices. The industry bait-and-switch runs on a low per-vent teaser that balloons once the van is in your driveway. Our price is one flat price per system, written down before any work starts, and it does not move at the door. You’ll see before-and-after photos of your own ducts. Estimates are free.

FAQs About Air Duct Cleaning in Rohnert Park
You’ll likely find original galvanized trunk lines with leaking seams, brittle flex branch runs that have collapsed or pulled loose at collars, and thirty-plus years of dust, pollen, and wildfire smoke residue settled into low spots. We run camera inspection first, then quote repair and cleaning together so you’re not surprised by additional work after we start. Call (361) 326-5060 for a free estimate.
Sonoma County’s wildfire season peaks August through October, and Rohnert Park’s inland Petaluma Valley location traps smoke longer than coastal towns. Homeowners near Foxtail Golf Club, The Links, and the Laguna de Santa Rosa corridor notice smoke smell at registers for weeks after the visible haze clears, so they schedule cleaning on wildfire timing rather than a spring maintenance calendar.
Yes. Rohnert Park’s Measure C rent-control ordinance, upheld in 2019, makes property managers treat duct cleaning as a low-cost habitability repair, so scheduling follows 12-month lease turnover rather than weather or complaints. We see concentrated booking from multi-unit owners in late spring and early summer as leases cycle.
Usually both, but the duct is the reservoir. A new filter stops new particles; it doesn’t remove what’s already settled in the trunk lines and flex runs. In Rohnert Park’s older systems, smoke particulate embeds in porous flex insulation and galvanized seam corrosion, then releases when the blower cycles. Cleaning removes the reservoir; sealing prevents recontamination from attic air.
Yes, and we recommend it. Dryer vent cleaning is a separate system but uses the same access visit, so bundling saves you a second trip charge. In Rohnert Park’s slab homes, dryer vents often run long horizontal routes through attics or soffits that are difficult for homeowners to inspect. We clean the full run and check termination clearance. Call (361) 326-5060 to add it to your estimate.
