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 Kentfield
Air duct cleaning in Kentfield means dealing with homes built into the slopes off Sir Francis Drake Blvd, where original sheet-metal trunks were extended piecemeal during decades of remodels. That creates duct runs that are unusually long, jogged, and genuinely hard to reach. We know these systems because we work on them every week. Our crews set up negative-pressure extraction with HEPA filtration, agitate the runs properly, and photograph what actually came out of your ducts before we pack up. Need a straight answer on whether your Kentfield home even needs cleaning? Call (737) 727-2314 and we’ll tell you honestly.
Why Cardinal Air Duct Cleaning Is Kentfield’s Preferred Air Duct Cleaning Company
Omar Haddad runs our Air Duct Cleaning operation with a rule that most companies in this trade quietly avoid: the answer can be “not yet.” Kentfield homeowners call us expecting a sales pitch and instead get a technician who inspects first and tells them the truth. Many of these 1950s and 1960s ranch homes have clean, well-sealed ducts that don’t need work. We’d rather lose that booking than push a cleaning your system doesn’t need.
The difference shows up in how we handle the job itself. Our technicians arrive in uniform, background-checked, with professional-grade equipment: Rotobrush rotary brush systems for agitation and Nikro HEPA-rated vacuums for extraction. Before any work starts, you get a written price for the entire system. One number. It doesn’t change at the door. And your booking moves through the Relay Standard: a live arrival window you can track on your phone, before-and-after photo proof, and a digital invoice payable by link. Nobody in Kentfield should have to guess when the crew will show up or what the final bill will be.
Air Duct Repair in Kentfield
Air Duct Repair in Kentfield often comes down to fixing what decades of piecemeal remodeling left behind. The original galvanized trunks in these hillside homes commonly get extended with flex runs during additions, and the joints where old metal meets newer flex are exactly where sagging, separation, and debris buildup happen. A homeowner might only notice a musty smell at one or two registers, but the actual problem sits deeper in the run.
Sealing Sagged and Separated Runs
When a flex run sags, it pools dust, construction debris, and sometimes insulation fibers pulled from an air handler closet. We locate the sag with a camera inspection, re-support the run, seal the joints, and extract whatever settled inside. The repair gets a written guarantee, and if it fails, that second visit is free. Most run repairs in Kentfield land between $220 and $480 depending on access and how much of the run needs re-sealing.
Return Trunk Repairs and Air Handler Closets
Older Kentfield homes frequently place the air handler in a closet that was never designed for the blower it now runs. The return trunk pulling air through that cramped space can draw insulation fibers and household dust directly across the motor. Our team rebuilds the return connection, seals the trunk, and sets negative pressure at the source so the repair holds. Expect $300 – $650 for a return-side repair involving trunk sealing and containment setup.
Ductwork Cleaning in Kentfield
Ductwork Cleaning in Kentfield is not a quick register-level vacuum job. The systems here are long and jogged, mixing old galvanized pipe with later flex additions. That patchwork geometry means proper source removal takes time. We set up HEPA-filtered negative pressure at the trunk so loosened debris gets pulled straight into the vacuum, not pushed back toward your air handler or living space. A typical full-system cleaning for a Kentfield home runs $450 – $750 total, one price per system, agreed before we touch a single duct.
Full System Source Removal
We work each run with agitation tools following the NADCA standards sequence. That means loosening the bonded dust on trunk walls, extracting it under containment, and then photographing the interior of the ducts so you can see the result. On a split-level off College Ave, the camera inspection before cleaning found a sagging flex return holding standing debris from an old addition. Our crew sealed the sag and extracted the buildup, and the before-and-after photos of that return told the whole story. That is the standard for every job here.
Supply and Return Run Cleaning
Many Kentfield systems only need targeted work: the return side pulls harder and accumulates more, while supply runs stay relatively clean. We’ll tell you if that’s the case for your home. Running targeted cleaning on one side rather than a full-system job often falls between $250 and $400. The price is written before work begins, and the scope stays what we agreed to.
Trusted Brands We Service in Kentfield
Our crews work on whatever your Kentfield home runs, but we stock and service the filtration and equipment brands these systems commonly pair with: Guardsman, Aprilaire, and Abatement Technologies among them. If your system uses a Guardsman media filter, we carry replacements. If your air handler needs a containment setup during cleaning, we bring Abatement Technologies units rather than improvising. For homeowners off Sir Francis Drake Blvd and College Ave, that means shorter turnaround on parts and no second trip because the right component was missing.
Common Air Duct Cleaning Problems We See in Kentfield Homes
- Piecemeal trunk extensions. Original 1950s – 70s sheet-metal trunks in Kentfield were often extended with flex during remodels. The transition joints collect debris and sag, which is where musty register smells come from in the rear bedrooms of split-levels off College Ave.
- Air handler closets pulling insulation. Tight closets housing blower motors draw insulation fibers from the surrounding walls and ceiling. We see this in ranch homes near Kent Woodlands where the closet was never sealed properly.
- Long, jogged runs hiding debris. Houses built into the slopes off Sir Francis Drake Blvd have unusually long duct paths with sharp jogs. A shop vac at the register won’t reach the debris sitting mid-run; only source removal under negative pressure will.
- Per-vent pricing that drifts upward. Kentfield homes look modest from the street but have long run footage. Quotes built on per-register pricing always climb once the crew sees the actual ducts. One flat price per system is the only honest model here.

FAQs About Air Duct Cleaning in Kentfield
How often do air ducts in a Kentfield home actually need cleaning?
Most Kentfield homes need duct cleaning every 4 to 7 years, not annually. The real triggers are visible dust blowing from registers, a musty smell when the system kicks on, recent remodeling that left drywall dust in the runs, or a home with pets and occupants with allergies. Many of these 1950s – 70s homes have clean, well-sealed ducts that need no work at all. We’ll inspect first and tell you if the answer is “not yet.” Call (737) 727-2314 for an honest assessment.
Do you charge per vent or one price for the whole system?
One flat price per system, written down before any work begins. We never quote per vent, because Kentfield’s jogged, multi-level duct runs make per-register pricing a trap: the house looks small from the street, the run footage is long, and the quote climbs once the crew is inside. Your price is the whole system, period. Call (737) 727-2314 and we’ll give you the number before you commit to anything.
Can I see what actually came out of my ducts?
Yes. Every Cardinal job includes before-and-after photographs of your own ducts, taken with a camera inside the runs. You’ll see the condition of the trunk before we start and the cleaned surface when we finish. On a split-level off College Ave in Kentfield, those photos showed a homeowner exactly what was sitting in the sagging return run that had been causing a musty smell in two rear bedrooms. If you can’t see the result, the work wasn’t done.
Do you offer same-day air duct cleaning in Kentfield?
We don’t promise same-day service, and we’d rather be honest about that than set an expectation we can’t meet. Duct cleaning in Kentfield is scheduled work because the systems are long, jogged, and genuinely slow to clean properly. What you get instead is a live trackable arrival window through the Relay Standard, so you know when the crew will show up and can plan around it, without sitting through a four-hour window. Call (737) 727-2314 to schedule.
Does cleaning ducts also cover the dryer vent?
No, the dryer vent is a separate service. We specialize in Air Duct Cleaning, HVAC Cleaning, and Dryer Vent Cleaning as three distinct jobs, because the ductwork, the air handler, and the dryer vent each need different tools and a different process. If you want both done, we’ll quote them separately and clearly, so you know what you’re paying for on each line. Call (737) 727-2314 and we’ll walk through what your home actually needs.
