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 Sebastopol
HVAC cleaning in Sebastopol homes typically runs $320 – $780 for a full system, and the honest answer is that most houses here need it every 2 – 3 years, not annually. What matters more than frequency is whether the job is done with real source removal and documented proof, which is exactly how we work. If you’ve noticed dust settling back on surfaces within days of cleaning, or your air handler smells musty when the heat kicks on, call (737) 727-2314 and we’ll walk you through what’s actually going on.
We know Sebastopol homes because we clean systems here week after week – from the orchard-era properties along Bodega Avenue to the newer builds off Gravenstein Highway. That local familiarity means we show up knowing what to expect from your duct layout before we even remove the first register.
Omar Haddad, who leads our team, insists on one thing above all: a written price for the whole system before any work starts. No per-vent math, no surprises after the camera inspection.
Why Cardinal Air Duct Cleaning Is Sebastopol’s Preferred HVAC Cleaning Company
Sebastopol homeowners call us because we run professional-grade equipment and we document the work. A Rotobrush rotary brush system does the agitation – that means the debris actually loosens from the duct walls instead of just getting a surface wipe. A Nikro HEPA unit handles negative-pressure extraction – that means the loosened debris goes straight into the vacuum, not back into your living room. And an Abatement Technologies containment unit keeps the work area sealed while we work.
Our technicians arrive background-checked and in uniform, and you’ll know the tech’s name before they pull up. Every booking through The Relay Standard gives you a live trackable arrival time, so you’re not waiting through a four-hour window during your day.
The 365-Day Done Right Promise backs every HVAC cleaning job in Sebastopol. If the work isn’t right within a full year, we return and correct it at no charge. That’s the longest-standing satisfaction window in the trade, and it applies to every booking without exception.
AC Duct Cleaning in Sebastopol
AC Duct Cleaning in Sebastopol means cleaning both the supply and return sides of your cooling system, and in this town it usually costs $280 – $450 for a typical single-system home. What drives the price here is the reality of Sebastopol’s housing stock: many homes combine rigid galvanized trunk lines from the original build with flex runs added during later remodels, and both need different agitation approaches but still fall under one flat system price.
We see this mix constantly from neighborhoods near the Laguna de Santa Rosa to streets off Occidental Road. The older galvanized sections hold years of fine dust and the newer flex runs trap it in the ribbed walls. A proper cleaning handles both without switching to per-vent pricing halfway through, which is what some companies do once they discover the trunk line complexity.
Why AC Duct Cleaning Matters Here
Sebastopol’s dry summer season means windows stay closed and the AC runs harder for stretches, pulling dust into the return side continuously. When that dust loads up the evaporator coil, your system works harder to push the same amount of cool air. We clean the coil side as part of the job, not as an add-on line item.
What We Actually Clean
The full AC duct path includes the return registers, the return trunk, the air handler interior, the supply plenum, and the supply branches to every room. We photograph the before and after at every stage so you see your own ducts, not a stock image.
Furnace Cleaning in Sebastopol
Furnace Cleaning in Sebastopol homes typically costs $320 – $520 depending on whether you have a single basement or crawlspace unit with short runs or a larger system with longer branch ducts. Fog season here, especially in the lower-lying areas near the Laguna, means damp air moving through ducts that may have accumulated dust all summer, and that’s a recipe for musty smells the first time the heat cycles on.
We clean the furnace side as its own full-system job: the heat exchanger area gets inspected and cleared, the blower wheel gets cleaned so airflow stays balanced, and the supply ducts get the same rotary brush and HEPA extraction treatment as the AC side. The goal is a system that runs cleaner and quieter, not a surface-level wipe that leaves the heat exchanger full of last season’s debris.
Blower and Heat Exchanger Focus
The blower motor in many Sebastopol furnaces pulls double duty – cooling season and heating season – so it accumulates a year-round coating of dust. A dirty blower wheel moves less air and runs hotter, which shortens motor life. We remove the blower assembly, clean the wheel and housing, and note any bearing noise before it becomes a failure.
Signs Your Furnace Ducts Need Cleaning
If your furnace kicks on and you smell dust or damp paper for the first minute, that’s the signature of accumulated material in the heat exchanger or supply ducting. You’ll also notice faster dust buildup on furniture during heating season, which means the system is circulating what’s already inside instead of just moving conditioned air.
Trusted Brands We Service in Sebastopol
We service and clean systems tied to Trane, Carrier, Lennox, Rheem, Goodman, and Mitsubishi units throughout Sebastopol, and our team knows the air handler layouts for each. Because we work here regularly, we keep common filters and coil treatment products on the trucks, which means fewer return trips to a supply house in Santa Rosa. When we recommend products like Guardsman coil treatment or Aprilaire filtration during an HVAC cleaning, they’re on hand and usually installed the same visit.
One practical note for Sebastopol homeowners with split systems: the outdoor condenser also needs attention. HVAC Cleaning for the full system includes condenser coil cleaning, which matters in Sebastopol because tree litter and pollen from the surrounding apple orchards and residential landscaping get pulled across the condenser fins all summer. Our team handles that as part of the same flat system price, not as a separate charge.
Common HVAC Cleaning Problems We See in Sebastopol Homes
- Remodel dust packed against the air handler coil. Sebastopol’s constant wave of kitchen and bath remodels means drywall and tile dust finds its way into return ducts and settles on the coil. We walked into a home off Healdsburg Avenue where the blower motor was cycling hot because drywall dust from a remodel had packed against the coil. Our tech ran a camera inspection through the supply and return ducts, found the blockage, and used negative pressure with agitation tools to pull it back to the source before sealing the registers. The homeowner got before-and-after photos of their own ducts and a flat price we agreed on before we started.
- Per-vent quotes that balloon once the camera inspection reveals extra trunk lines. Sebastopol’s older orchard-era homes often have long, branched galvanized runs that make per-vent pricing explode. We quote one flat price per system up front, and it doesn’t shift when we find a fifth or sixth branch line.
- Dust settling back within days because the air handler side was skipped. If source removal on the blower and coil isn’t part of the job, dust left in the branches just migrates back into the living space. Our process treats the air handler as part of the duct system, not an optional extra.
- Flex runs treated like rigid pipe, or vice versa. Many Sebastopol homes have both. Flex needs lower-torque agitation so it doesn’t tear, and rigid galvanized needs stiffer brush contact to actually clean the walls. Using the wrong tool on either means a cleaning that didn’t clean.

FAQs About HVAC Cleaning in Sebastopol
Every 2 – 3 years is the honest answer for most Sebastopol homes. Homes near the Laguna de Santa Rosa or with pets and regular window-open seasons may trend shorter; newer tight-built houses with good filtration can go longer. If you haven’t had it done in five years and you’re noticing dust return within days of vacuuming, it’s time. Call (737) 727-2314 and we’ll help you figure out if cleaning is actually warranted or if you can wait.
We charge one flat price per system, agreed in writing before any work starts. No per-vent pricing, ever. That matters in Sebastopol specifically because many older homes have long, branched galvanized trunk lines where a per-vent quote would quietly double once a camera inspection reveals how many runs actually exist. Your written price covers the whole thing.
Yes, and that’s how most Sebastopol homeowners do it. A full system cleaning covers the return side, supply side, air handler, blower, coils, and condenser in a single visit, usually in 4 – 6 hours depending on home size. One flat price covers the full job. Call (737) 727-2314 to book and we’ll confirm the scope before we arrive.
You get photos of your own ducts – the return trunk, the supply branches, the air handler, and the coil – taken before we start and after we finish each section. It’s not stock imagery. If dust was packed against your coil or built up along the return walls, you’ll see the difference, which means you’ll know the work was actually done. The photos come with your digital invoice and are part of every booking.
No, we don’t offer same-day service. HVAC cleaning is a scheduled job, and we don’t rush it. What we do offer is a live trackable arrival window through The Relay Standard, so when you book, you know when we’re coming and you can watch the tech’s arrival in real time from your phone. Call (737) 727-2314 and the person who answers will get you on the schedule without a voicemail loop.
