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 HVAC Cleaning Across Rohnert Park
If your HVAC system is pushing dust back into the air every time the blower kicks on, the fix is source removal cleaning, not just brushing off the registers. On most Rohnert Park homes, a full HVAC cleaning – coils, blower, ducts, and air handler – runs $480 to $1,100 depending on system size and the condition of the ductwork. We schedule Rohnert Park jobs every weekday, and a live person answers when you call (737) 727-2314. You get a written price before any work starts, and every job is backed by our 365-Day Done Right Promise.
Why Cardinal Air Duct Cleaning Is Rohnert Park’s Preferred HVAC Cleaning Company
Rohnert Park’s housing stock is not like Santa Rosa’s or Petaluma’s. Most of the homes here are mid-century tract builds and Eichler-style ranches from the 1960s and 70s, and their duct systems were installed with sheet metal, mastic sealant, and flex runs that have now seen six decades of Sonoma County air. Our technicians know what that means before they even open a return grille. We find brittle mastic, disconnected flex runs in attics, and debris loads that register-only cleaning would never touch.
Every Rohnert Park job gets the same standard. The tech arrives in uniform, background-checked, with professional-grade equipment from Rotobrush and Abatement Technologies. You know the tech’s name before they open the front door. We do not quote per vent. We quote one flat price per system, written down and agreed to before a single duct is touched. That is the only honest way to price a mid-century home where a single return trunk can run 20 feet and hold more debris than the registers ever suggest. The 365-Day Done Right Promise covers every booking, no exceptions: if the work is not right within a full year, we come back and correct it at no charge.
AC Vent Cleaning in Rohnert Park
AC Vent Cleaning in Rohnert Park usually means more than vacuuming the visible grilles. On homes along Country Club Drive and around Crane Creek, the supply registers are connected to sheet-metal ducts that run through hot attics all summer. Dust, pet dander, and years of smoke-tinged air collect along the interior walls of those ducts, and every cooling cycle carries particles back into living spaces. A proper cleaning agitates that buildup at the source and extracts it with negative pressure at the air handler, so it leaves the house instead of recirculating. On a typical Rohnert Park home, AC vent and supply duct cleaning runs $180 to $320 as part of a full system job.
What the job actually involves
We access the supply runs at each register and at the main trunk. A Rotobrush whip breaks the adhered dust layer loose, while a Nikro HEPA vacuum pulls negative pressure on the whole run. You get before-and-after photos of your own ducts on a tablet before we pack up. If a flex run has disconnected in the attic, we find it and reconnect it.
When to book it
The honest answer: not every year. If you have pets, recent remodeling, or you ran the system nonstop during the 2020 and 2021 wildfire smoke seasons, it is likely overdue. If the registers show visible dust bloom when the AC starts, call us. If you see dust settling on furniture within days of wiping it down, call us sooner.
Furnace Duct Cleaning in Rohnert Park
Furnace Duct Cleaning in Rohnert Park is the most common job we book in January and February, when the gas furnace has been cycling for months. Homes in the Ridgway and Scenic Vista area run furnaces hard through the winter, and those systems pull air through returns that often draw from hallways and living spaces where dust and skin cells concentrate. On a mid-century Rohnert Park house, a furnace duct and return cleaning typically runs $300 to $550 as a standalone service, or is bundled into a full HVAC cleaning at a better per-system rate.
Blower and heat exchanger cleaning
The furnace blower wheel on a 50-year-old system can look like a felt pad when we first inspect it. That buildup throws the wheel out of balance, shortens motor life, and reduces airflow. We clean the blower assembly and heat exchanger surfaces, then re-check static pressure to confirm the system is moving air the way it should.
Why the return side matters most
On Rohnert Park’s original sheet-metal systems, the return trunk is often a single long run fed by two or three wall grilles. That design holds far more debris than modern systems with multiple returns. A camera inspection before cleaning shows exactly what is in there, and the after photos prove what was removed. We do not skip this step.
Trusted Brands We Service in Rohnert Park
We clean and service systems from every major manufacturer you will find in Rohnert Park homes: Carrier, Trane, Lennox, Rheem, Goodman, and York among others. When repairs are needed, we stock common parts locally and source others quickly, which means shorter turnaround for Rohnert Park customers. Our filtration recommendations lean on Guardsman and Aprilaire products where a home needs better particulate capture, especially after smoke-heavy seasons or in households with allergies. We run Rotobrush and Abatement Technologies equipment on every job because a truck-mount vacuum without proper negative pressure setup at the air handler can blow loosened dust back through your blower motor and into the house. We do not use shortcuts that create that problem.
Common HVAC Cleaning Problems We See in Rohnert Park Homes
- Disconnected or crushed flex runs in attics. On 1960s and 70s tract homes, original duct runs often separate at the collar or get flattened by stored boxes. The system gets “cleaned” but two bedrooms still get no airflow. We camera-inspect and reconnect as part of the job.
- Brittle mastic and leaky joints. Original sealant on mid-century sheet-metal ducts crackles and falls away over time. That means conditioned air leaks into the attic, and attic dust gets pulled into the system. We document and seal these leaks during cleaning.
- Blower wheels packed with years of dust and pet hair. The blower assembly on a Rohnert Park furnace that has not been cleaned in a decade can be carrying a half-pound of fine particulate. That is added strain on the motor and a direct source of the dust level inside the home.
- Smoke-season residue inside the return trunk. During wildfire advisories, homeowners run the blower continuously with windows closed. That pulls smoke-tinged air through the return trunk, where particles stick to existing dust. The result is a persistent stale odor even after the sky clears. Source removal is what addresses it.
Pricing for HVAC Cleaning in Rohnert Park, CA
Here is what you should expect to pay in Rohnert Park for a real HVAC cleaning. A standard single-system home with a furnace, AC coil, and 8 to 14 registers runs $480 to $750. Larger homes with two systems or long multi-story duct runs run $800 to $1,100. The price is one flat figure per system, written down and agreed to before we start. You will never see a per-vent line item on our invoice, because per-vent pricing on mid-century Rohnert Park homes does not reflect the actual work. What affects cost: system count, duct length, accessibility of the air handler and coil, and how long the buildup has been accumulating. Call (737) 727-2314 and we will give you a straight range over the phone, then confirm a written price on site before any work begins. Estimates are free.

FAQs About HVAC Cleaning in Rohnert Park
Every 4 to 7 years for most homes. The exceptions in Rohnert Park are homes with shedding pets, recent remodels, or systems that ran continuously through wildfire smoke seasons. If your mid-century sheet-metal ducts have never been cleaned, or you cannot remember the last time, they are overdue. Call (737) 727-2314 and we will help you decide if a cleaning is warranted before you spend a dollar.
Per system, always. Rohnert Park’s mid-century homes frequently have a single return trunk 20 feet long that holds far more debris than the register count suggests. Charging per vent would either overcharge the customer or underprice the real work. We quote one flat price for the entire system, written down before any work starts.
We went to a 1968 ranch off Enterprise Drive near the SMART station where the homeowner had been running the central system every afternoon during a smoke advisory. Our tech cut a camera inspection port at the main trunk and found the return duct lined with an eighth-inch mat of drywall dust and framing debris from a 2019 remodel, plus a disconnected flex run feeding a back bedroom. We set up negative pressure with HEPA filtration at the air handler, ran agitation tools and a Rotobrush whip through the supply and return ducts, reconnected the flex run, and showed the homeowner before-and-after photos of their own ducts on a tablet before we packed up. That is the process, on every job.
Because smoke particles stick to whatever is already inside the ducts, and running the blower on recirculate keeps pushing that odor back into the living space. Window closures and continuous fan use during an advisory pull smoke-tinged air through aging sheet-metal returns. A source-removal cleaning with HEPA extraction is what removes that residue. Call (737) 727-2314 after a smoke season and we will give you an honest assessment.
We do not promise same-day service, because a real HVAC cleaning is not a 45-minute job and we will not cut corners to hit a clock. Rohnert Park jobs are scheduled, with a firm arrival time you can track live through The Relay Standard booking experience. If your system has failed or you have an immediate air quality problem, call (737) 727-2314 and a live person will get you on the schedule as soon as is realistic.
