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.

Why Cardinal Air Duct Cleaning Is Tamalpais-Homestead Valley’s Preferred HVAC Cleaning Company
Homeowners around Homestead Valley and Tam Junction keep calling us because we do the job the way a local should: we show up with the right equipment, we explain what we’re doing in plain English, and the price you sign off on is the price you pay. Led by Omar Haddad, our crew works on Rotobrush rotary brush systems and Nikro HEPA vacuums, not truck-mounted shop vacs that blow debris around and call it a day.
We’ve worked in enough 1950s and 1960s ranch homes along Route 1 and the Mill Valley border to know what those ducts look like inside. Lint. Dust. Sometimes decades of it. Our techs are background-checked and uniformed, and you’ll know their name before they knock. The Relay Standard booking means you get a live trackable arrival window, before-and-after photo proof, and a digital invoice you can pay from your phone. That standard applies to every job in Tamalpais-Homestead Valley, no exceptions.
Evaporator Coil Cleaning in Tamalpais-Homestead Valley
Evaporator coil cleaning in Tamalpais-Homestead Valley is the single most overlooked piece of HVAC maintenance we see. The coil sits inside your air handler, and when it’s caked in dust and grime, the system has to work harder to pull heat out of your air. In a canyon where many homes barely run cooling all summer, the coil gets coated in a sticky film that bakes on when the heat does kick in. We pull the access panel, inspect the coil, apply a proper coil cleaner, and rinse it so airflow and heat transfer return to spec. Most evaporator coil cleanings in Tamalpais-Homestead Valley run $120 – $225 as a standalone service, or they’re bundled into a full system cleaning.
Signs Your Coil Needs Attention
If your system runs longer than it used to and your energy bills tick up without a reason, the coil is usually the first place we look. Another tell: supply air that feels lukewarm on cool mode. A clean coil fixes both, and it takes our techs under an hour on most residential units.
What We Do In the Air Handler
While the coil is out, we clean the blower motor and housing at the same time. Dust on the blower wheel throws off balance and shortens motor life. The whole air handler cleanout is part of why we ask to see the system before we quote, so nothing gets missed.
AC Duct Cleaning in Tamalpais-Homestead Valley
AC duct cleaning in Tamalpais-Homestead Valley is about getting the debris out of the trunk lines, not just the visible register openings. Homes here sit in a marine-layer climate where the system goes dormant for long stretches. That means dust settles in the ducts and stays there, collecting layer by layer until the first hot spell sends it blasting into your living room. We connect a negative-pressure HEPA vacuum to the supply and return plenums, then run rotary agitation tools through the trunk lines to knock debris loose. The vacuum stays running the whole time, so what comes off the duct walls goes into the collection bag, not back into your home. A full AC duct cleaning in Tamalpais-Homestead Valley runs $295 – $585 for a typical single-family home.
Camera Inspection Before, Photo Proof After
Before we touch anything, we run a camera through the supply and return ducts and we show you what we see. That’s the baseline. After we finish, we photograph the same duct runs so you can compare. You’re not taking our word for it; you’re looking at your own ducts on your own phone.
No Per-Vent Pricing, Ever
The per-vent model is how duct cleaning becomes a bait-and-switch. A low coupon, then a fee for each register. We don’t price that way. One flat price per system, written down before work begins, and it covers the trunk lines, branches, plenums, coil, and blower. The number you sign for is the number on the invoice.
Trusted Brands We Service in Tamalpais-Homestead Valley
Our crews in Tamalpais-Homestead Valley work on every major residential system, from Trane and Carrier to Rheem and Lennox. We stock common Aprilaire and Guardsman filtration products in the van, so if your filter media needs replacing during a cleaning, we handle it on the spot. Abatement Technologies containment units stay in our rotation for homes where duct contamination is heavy enough to warrant isolation, which keeps dust from migrating into finished spaces during the job. If you’re not sure what’s in your mechanical closet, call (737) 727-2314 and describe the unit; we’ll tell you what to expect before we schedule.
Common HVAC Cleaning Problems We See in Tamalpais-Homestead Valley Homes
- Canyon dust on Homestead Boulevard and Montford Avenue: The valley catches a lot of airborne dust from the hills and the highway corridor. Homes within a block of Route 1 collect road dust in ducts noticeably faster than homes tucked into the hillsides off Panoramic Highway.
- Stagnant off-season buildup: Because coastal fog keeps summer temperatures moderate, many systems here barely cycle from June through September. That stillness lets debris settle deep into trunk lines. When the first cold snap hits in November, it all moves at once.
- Old ranch-home ductwork on Tam Junction streets: A lot of the housing stock around Tamalpais Valley and Homestead Valley dates to the 1950s and 1960s. Ductwork that old often gaps at the seams, which pulls dust from crawlspaces and attics into the system. We flag those joints when we see them on camera.
- Fog-driven moisture and filter neglect: Marine air means higher relative humidity, which binds dust to duct walls and speeds up filter loading. A filter that should last 90 days gets clogged in six weeks, and that backs up pressure across the whole system.
Pricing for HVAC Cleaning in Tamalpais-Homestead Valley, CA
A full HVAC cleaning in Tamalpais-Homestead Valley typically runs $295 – $585 for a single-family home with one system. That covers supply and return trunk lines, all branch ducts, plenums, the evaporator coil, and the blower motor. Evaporator coil cleaning as a standalone job runs $120 – $225. Condenser cleaning runs $85 – $140. If your home has two systems or unusually long duct runs, the quote reflects that before we begin.

Omar Haddad can walk you through what your specific setup will cost.
One thing we say plainly because it matters: some homes don’t need a full cleaning. If the ducts are clean and the coil is clean, we’ll tell you that and charge you nothing for the inspection.

FAQs About HVAC Cleaning in Tamalpais-Homestead Valley
Most homes in Tamalpais-Homestead Valley do well with a full duct cleaning every 2 – 4 years. The valley’s fog and marine air mean systems often sit idle for months, letting dust build up without airflow to move it. Homes on Route 1 or within a block of the highway corridor may need it on the shorter end of that range. If you have allergies, pets, or you’ve done recent remodeling, clean sooner rather than later. Call (737) 727-2314 and we’ll help you gauge it based on your address and system age.
We charge one flat price per system, never per vent. A per-vent price rewards cleaning a lot of registers while ignoring the trunk lines where debris actually collects. Our price covers the whole system: trunk lines, branches, plenums, coil, and blower. The written quote you get before work starts is the invoice at the end.
We start with a camera inspection of the supply and return ducts, then set up negative-pressure extraction with a HEPA-filtered Nikro vacuum. We run Rotobrush rotary agitation tools through the trunk lines to loosen debris while the vacuum pulls everything to the collection point. Then we clean the evaporator coil and blower motor in the air handler. You get before-and-after photos of your own ducts before we leave. The entire job takes about 2 – 4 hours on a typical ranch home in Tamalpais Valley.
We schedule every job, and we don’t promise same-day dispatch. What we do promise is a live trackable arrival window through The Relay Standard, so you’re not stuck in a four-hour holding pattern. A real person answers the phone 24/7 at (737) 727-2314, and we’ll get you on the calendar for a time that works, with your tech’s name sent before they arrive.
We run professional-grade Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units when a job calls for isolation. No shop-vac shortcuts. We also carry Aprilaire and Guardsman filtration products in the van for filter swaps. The equipment is part of why we can photograph clean duct walls after we’re done.
