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 HVAC Cleaning Across Kentfield
Most HVAC cleaning jobs in Kentfield run between $385 and $720 for a full system on a typical 2,000-to-3,000-square-foot home, and the work usually takes half a day. We give you that number in writing before any equipment comes off the truck, so the invoice you see at the end matches the quote you approved at the start. That’s not how most duct cleaners in Marin operate, and we know it. If you’re off Sir Francis Drake, up in Murray Park, or tucked into a hillside lane near the College of Marin, our crews know the drive, know the houses, and know what those old crawlspaces do to a duct run. Call (737) 727-2314 and a live person answers, day or night.
Why Cardinal Air Duct Cleaning Is Kentfield’s Preferred HVAC Cleaning Company
Kentfield homeowners tend to do their homework before letting anyone into their mechanical systems. The houses here are not disposable tract builds. Many are mid-century ranch homes with original rigid metal ducting, and the newer hillside rebuilds often carry multizone systems with high-end filtration. Our HVAC Cleaning team treats those systems with the care they deserve. Every technician is background-checked and arrives in uniform, and you’ll know the tech’s name before the door opens. That matters when someone is going to be crawling through your attic or under your house. Omar Haddad, who runs our operations across the Bay Area, holds every job to the same standard: a written price before work starts, before-and-after photos of your actual ducts, and the 365-Day Done Right Promise behind every booking. If the work isn’t right within a year, we return and correct it at no charge.
Furnace Cleaning in Kentfield
Furnace cleaning is the workhorse of this trade in Kentfield, and for good reason: the furnace pulls return air from your living space through ducts that sit in crawlspaces and attics all year, accumulating whatever the Marin air throws at them. In Kentfield, that means fine dust, pollen from oak and madrone, and in the older homes, flecks of rust and debris from metal runs installed before flex duct even existed.
What We Clean Inside the Furnace
We pull the blower motor assembly, clean the fan blades with soft brushes and compressed air, and vacuum the blower compartment with a Nikro HEPA-rated negative-air setup. Heat exchangers get inspected and dry- brushed where the buildup isn’t welded on, and the burners are checked for proper flame. Most importantly, the evaporator coil gets cleaned when accessible. A coated coil costs you efficiency and can force the compressor to run harder than it should.
When a Kentfield Home Needs It
If your furnace blows dust into the room when it starts, or the house smells like old paper bags when the heat kicks on for the first time each fall, the ducts and blower are usually the culprit. How often it’s genuinely needed varies. A home with two shedding dogs, a wood- burning fireplace, and thirty-year-old return runs under the floor will need this far sooner than a single couple with slab ducting and a MERV-13 filter habit.
Omar Haddad always pushes our techs toward source removal over surface cleaning. Sweeping debris toward the trunk and hoping the filter catches it is not the job. The job is getting it out of the house. A furnace cleaning in Kentfield typically runs $250 to $410 as part of a full system clean.
AC Vent Cleaning in Kentfield
AC vent cleaning in Kentfield is about the supply and return registers, the branch ducts feeding them, and the plenum boxes sitting just behind the wall. It’s also where the per-vent gimmick lives in this industry. A tech quotes you $39 per vent, then counts 22 openings across your house, and suddenly a $400 job is an $858 invoice after taxes and fees.
Why a Flat Price Per System Matters Here
We don’t price by the vent. Kentfield homes often have 15 to 25 registers across multiple zones, and per-vent pricing turns a straightforward job into a surprise number. That’s not a price. That’s a guessing game you get to pay for. Our quote is one flat price per system, agreed to before we begin, and it doesn’t change at the door.
What the Registers Get
Each register grille comes off, gets scrubbed with a brush and a degreasing wipe where needed, and the opening is vacuumed back a few feet into the branch. If there’s an accessible plenum box, we open it, inspect it, and extract what’s collected there. We also check for disconnected branches and crushed flex duct behind the register, because a register that’s blowing weak is sometimes a supply run that’s fallen off a joist in the crawlspace. AC vent cleaning in Kentfield as part of a whole-system job falls between $150 and $250 in addition to the trunk-and-blower work.
Trusted Brands We Service in Kentfield
We work on and alongside all the usual residential names you’ll find in Kentfield’s mechanical closets: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and Amana, plus Honeywell controls and Aprilaire filtration. We run Rotobrush rotary brush systems for branch duct agitation and Abatement Technologies negative-air containment units at the air handler while we work. That combination means the debris gets captured at the source instead of moved around your house. Since we stock common-size filters, grille fasteners, and plenum capping material on our vans, we can usually repair minor register and filter-frame damage the same visit, without waiting on a parts order.
Common HVAC Cleaning Problems We See in Kentfield Homes
- Original metal runs packed with decades of fibrous debris. Mid-century ranch homes in Kentfield typically have original rigid metal duct runs in uninsulated crawlspaces or attics. Those runs collect pollen, dry oak leaf fragments, and sometimes rodent-nest debris differently than flex duct does.
- Heavy seasonal pollen and leaf litter loading. Kentfield’s oak-and-madrone canopy means ducts here see heavier seasonal pollen and leaf litter loads than the flats on the other side of the 101. That’s a real difference we track in the field.
- Musty furnace smells that come back no matter how many filters get replaced. A homeowner on Sir Francis Drake Boulevard called after noticing a musty smell every time the furnace kicked on. Our tech ran a camera inspection down the main return trunk and found a thick mat of pollen, dry oak leaf fragments, and rodent-nest debris sitting on top of one of the registers. Before-and-after photos of that trunk went straight to the homeowner before we packed up.
- Multizone systems where one floor never seems to warm right. Newer hillside rebuilds in the Ross Valley often run multizone heat pumps with static pressure issues. A good duct cleaning with proper filter sizing can restore airflow to the far zones without touching the condenser.

FAQs About HVAC Cleaning in Kentfield
How often does a Kentfield home actually need HVAC duct cleaning?
Most Kentfield homes need a full duct cleaning every 3 to 5 years. If you live under heavy oak or madrone canopy or share the house with shedding pets, aim for every 2 to 3 years. If you just moved into a mid-century home and have no record of prior cleaning, do it once and start the clock fresh. Beyond that, trust the photos. We show you your ducts before and after so you can see whether there was actual loading worth addressing. For an honest assessment of your system, call (737) 727-2314.
Do you charge per vent or a flat price per system in Kentfield?
We charge one flat price per system, agreed before we start. Never per vent. Kentfield homes often have 15 to 25 registers across multiple zones, and per-vent pricing turns a straightforward job into a surprise number. You’ll get the total cost in writing, and it does not change at the door. Call (737) 727-2314 and we’ll give you a firm number.
What does the process actually look like inside my Kentfield home?
We seal off the system with Abatement Technologies containment units at the air handler, run negative-pressure extraction with Nikro HEPA vacuums, and agitate the branch ducts with Rotobrush rotary tools. Debris moves from the ducts into the vacuum, not back into your living spaces. You get before-and-after photos of your own ducts as proof. Call (737) 727-2314 and we’ll walk you through the whole process.
Can you come out the same day I call?
We don’t promise same-day service. Honest duct cleaning is a scheduled half-day job with real equipment and a real technician, and we’d rather give you a firm arrival window you can track than a rushed slot that compromises quality. That said, the office will work with you on the soonest available time. Call (737) 727-2314 and the live person on the line will find you a slot.
What brands of equipment do you service and work with in Kentfield?
We service and work alongside Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and Amana, plus Honeywell controls and Aprilaire filtration. Our own equipment includes Rotobrush rotary cleaning tools, Nikro HEPA vacuums, and Abatement Technologies negative-air containment units. If you’re running a high-efficiency Aprilaire filter box or a multizone Honeywell control system, we’re familiar with both and stock compatible filters on many of our vans. Call (737) 727-2314 with your system details.
