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 Larkspur’s Preferred Air Duct Cleaning Company
Larkspur homeowners call us because we do not play the per-vent pricing game. A national franchise might quote $99 and then stack per-vent upcharges once the tech is in your hallway. We hand you a written system price before work begins, and that number does not move. Omar Haddad, our owner, built the Larkspur operation around total visibility, which is why every booking includes a live trackable arrival window through The Relay Standard and before-and-after photo proof of your ducts. You will know your technician’s name before you open the door, because background-checked, uniformed techs are the only kind we send.
Our crews run professional-grade gear: Nikro HEPA-rated vacuum extraction units and Abatement Technologies containment systems, not a truck-mounted shop vac with a long hose. That distinction matters in Larkspur, where older duct runs hide years of accumulated Marin County dust and construction debris. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, with crews serving Larkspur locally. The 365-Day Done Right Promise means if the work is not right within a full year, we come back and fix it at no charge. No fine print, no exceptions.
HVAC Duct Cleaning in Larkspur
HVAC Duct Cleaning in Larkspur means removing the built-up debris from your supply and return ductwork using source-removal techniques, which is the trade term for loosening material from duct walls and extracting it directly into a HEPA-filtered vacuum under negative pressure, never pushing it back into your living room. A Larkspur home typically needs this when occupants have allergies that flare indoors, when visible dust is collecting on registers weeks after cleaning, or after any remodel that generated drywall dust. Standard whole-system HVAC duct cleaning in Larkspur runs $395 – $735 depending on the number of systems and the length of the runs.
Supply and return ductwork
We clean both sides of the system. Supply ducts deliver conditioned air to your rooms. Return ducts pull air back to the air handler. In Larkspur, return ducts are often the grimier side because they run low and collect whatever settles out of the air. Some companies only push tools through the supplies and call it done. That misses half the job.
Air handler and blower access
Proper HVAC duct cleaning includes cutting an access point at the air handler and running agitation tools through every reachable duct branch. The blower compartment should be inspected too. A blower caked in lint and dust is working harder than it should, and Larkspur homeowners are often surprised by what we photograph in there.
Vent Cleaning in Larkspur
Vent Cleaning in Larkspur focuses on the registers and grilles at the ends of your duct runs, plus the visible portions of the vent boot behind them. This is a lighter service than full HVAC duct cleaning, and it is the right call for a Larkspur bungalow with a short duct run, a clean air handler, and no sign of deep buildup. Expect to pay $120 – $220 for vent cleaning on a typical single-story Larkspur home. If your registers are dusty but your system is young and clean, this may be all you actually need, and we will tell you that plainly.
Register and grille service
We remove each register, clean the visible boot with brush and vacuum, and wipe down the grille faces. This is quick work, but it removes the dust you see every day. For homes on Magnolia Avenue with original 1950s registers, we are careful with the wall stacks, old metal, and paint layers.
When vent cleaning is the honest answer
If a tech tries to sell you a full duct cleaning on a 900-square-foot bungalow with a ten-foot return run, smile and get a second opinion. We would rather do the light touch, stand behind it with the 365-Day Done Right Promise, and keep a customer for fifteen years than oversell one job today.
Trusted Brands We Service in Larkspur
We maintain and clean systems built around Nikro HEPA filtration equipment, Honeywell filtration products, Aprilaire whole-home air cleaners, and Abatement Technologies containment units. Our techs carry common replacement parts for these brands on the truck, which means fewer second visits for Larkspur customers. And because each Cardinal location is independently owned but held to The Relay Visibility Guarantee, you get the same documented standard whether we are in a flat bungalow near Sir Francis Drake Boulevard or a hillside rancher off Park Terrace Drive.
Common Air Duct Cleaning Problems We See in Larkspur Homes
- Long horizontal return runs on hillside ranchers. Larkspur’s 1960s hillside homes often have return ducts that run flat and long under the floor structure. Debris settles in the middle of the run where shallow vacuum equipment never reaches, and without camera inspection you would never know it is there.
- Drywall dust from remodels. Marin County construction booms have hit Larkspur hard, and fine drywall dust infiltrates ducts during any wall or ceiling work. That dust then recirculates through the home for years unless the system is cleaned afterward.
- MERV filter mismatches. Many Larkspur homeowners install high-MERV filters to fight wildfire smoke and allergies. But without the blower to support that airflow restriction, the system suffocates. We flag this mismatch during duct inspections.
- Lint accumulation in return ducts near laundry areas. In Larkspur homes where the laundry is in a hallway or garage space adjacent to a return, we regularly see lint that has bypassed the dryer filter and been pulled into the return duct, creating a fire-load and airflow restriction at the same time.

FAQs About Air Duct Cleaning in Larkspur
Most Larkspur homes need full duct cleaning every 3 to 5 years, and less often if the home has a short duct run, no pets, and a clean blower motor. If you have a single-story bungalow with a ten-foot return run and no remodel dust, you may go seven years with just register cleaning. Call (737) 727-2314 and we will help you decide honestly, even if the honest answer is to save your money this year.
The price is a flat rate for the entire system, agreed in writing before work starts. We never charge per vent. Per-vent pricing on a Larkspur rancher with long horizontal returns is how upcharge crews turn a $99 teaser into a $900 invoice. You will know your number before we set up equipment.
Yes. Every Larkspur job includes before-and-after photos of your ducts, taken with inspection cameras, as part of The Relay Standard. You see exactly what we found and what the ducts look like when we finish. No mystery, no “trust us” moment.
Source removal is the industry term for physically dislodging debris from your duct walls using rotary brushes and air agitation, then extracting it into a HEPA-filtered vacuum system under negative pressure, meaning air is pulled out of the ducts rather than blown through them. In your Larkspur home, that means the debris goes into a sealed vacuum, not back into the air you breathe.
Yes, dryer vent cleaning is a separate service from air duct cleaning, and it is critical for long runs. Larkspur hillside homes often have dryer vent runs that travel fifteen feet or more through walls to an exterior outlet, and the lint load in those runs is a genuine fire hazard. We use Nikro and Rotobrush equipment made for that task, and we document the before and after the same way. Call (737) 727-2314 to schedule both services in one visit.
