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.

AfterAir Duct Cleaning in Corte Madera, CA: What It Really Costs and What We Actually Do
Air duct cleaning in Corte Madera typically runs $450 – $850 for a full system on a standard single-family home, and most jobs are completed in one visit that lasts three to six hours. The price depends on the number of systems (most Corte Madera homes have one furnace or air handler), access to the crawlspace, and how much debris has accumulated in the return and supply runs. At Cardinal Air Duct Cleaning, you get one flat price per system before a single duct is touched, and that number does not change when our technician is standing in your hallway. You can see it in writing first. Call (737) 727-2314 for a free estimate in Corte Madera, and we’ll walk you through exactly what your home needs.
We’re Omar Haddad and the team at Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005.

Air Duct Cleaning done right here requires equipment built for damp, silty conditions, and that’s exactly what we run.
Key Takeaways:

- We run Rotobrush, Nikro, and Abatement Technologies equipment – HEPA filtration on every job
Why Corte Madera Homes Need a Different Standard of Duct Cleaning
Corte Madera is built on the marshland edge of Richardson Bay, and that single fact changes what an honest duct cleaning involves. Many crawlspaces here see seasonal damp and fine silt that get drawn into return ducts. Marin’s marine layer keeps outdoor humidity high enough that we often find duct surfaces with the same clammy film you’d get on a window. That combination means source removal and negative pressure matter more here than the dry-dust blow-through you’d see in inland cities. If a crew shows up with a shop vac and a brush on a drill, the loosened debris is going straight into your living room. That’s not cleaning. It’s rearranging.
Our technicians know what Corte Madera’s housing throws at a duct system. Homes along Tamalpais Drive, the split-levels in Chapman Park, the newer builds near the Village, the older ranch-style houses up toward Christmas Tree Hill – each has its own access challenges and duct layouts. We send background-checked, uniformed techs who know their way around the whole town, from the 94925 flats to the hillside streets. And every single job includes a live trackable arrival window through The Relay Standard, so you’re never sitting around wondering if anyone is actually coming.
We answer the phone with a live person, 24/7. No voicemail loops. Call (737) 727-2314 and you’ll talk to a human being who can schedule you for an Air Duct Cleaning in Corte Madera appointment that fits your week.
How Much Does Air Duct Cleaning Actually Cost in Corte Madera?
Most standard air duct cleanings for a Corte Madera home run $450 – $850 per system. A typical single-family house here has one system (one furnace or air handler connected to a network of supply and return ducts). Larger homes on the hillside with two systems will be at the higher end or beyond. Here’s the breakdown:
| Service | Typical Price in Corte Madera | What’s Included |
|---|---|---|
| Residential Duct Cleaning (full system) | $450 – $850 | Supply and return runs, blower motor bay, one flat price per system |
| Supply Duct Cleaning | $250 – $450 | Supply runs only, written price before work starts |
| Return Duct Cleaning | $200 – $380 | Return runs only, includes air handler access |
| Air Duct Inspection with Video Camera | $150 – $250 | Camera walk-through, findings in plain language, photo documentation |
These are the numbers we quote for Corte Madera’s market. The things that actually move the price: how many systems you have, how much damp silt and debris has accumulated (Marin moisture causes duct walls to hold more than inland homes), and whether your crawlspace access is tight enough to need a two-person crew. You’ll know the flat price per system before any work starts. That price is written and handed to you. It does not change at the door.
And here’s the answer to the question most people are really asking: why are some Corte Madera duct cleaning quotes so much cheaper? Because those crews quote per vent. They give you a low per-vent number and then suddenly your home has 30 vents, plus a furnace cleaning fee, plus a return duct surcharge. You said yes to a number and got a bigger one. We don’t do per-vent pricing, and we never have. One flat price per system, agreed before we unpack a single tool.
Ductwork Cleaning in Corte Madera
Ductwork cleaning in Corte Madera is what we do most, and the process matters just as much here as the result. First, we inspect your ductwork with a camera so you can see what’s actually in there. Then we set up negative-pressure extraction – that means the loosened debris goes straight into a HEPA-filtered vacuum, not back into your living room. We use a Rotobrush rotary brush system for agitation on the supply and return runs, and Nikro HEPA vacuums for the extraction. If your crawlspace has tight or awkward access (plenty of Corte Madera homes do), we send a two-person crew. Then we photograph every section of the work, before and after, so you can see what came out and what the ducts look like now.
How often do Corte Madera homeowners genuinely need ductwork cleaning? Most honest answer: every three to five years for a typical household, but sooner if you have pets, you renovate, or you live close to Richardson Bay where the damp and silt cycle runs faster. If you just moved into a house and you don’t know the last time the ducts were touched, that’s a good reason to have a camera inspection done first.
Source Removal on Return Runs
In Corte Madera, return ducts carry the heaviest load of damp fine silt, especially in crawlspace-vented homes. We don’t skip the return run. Plenty of cheap crews do, because it’s the hardest to access. Missing it means you’ve cleaned half the system and left the dirtiest half untouched.
Supply Run Agitation and HEPA Extraction
Supply runs tell you how much dust is being blown into your rooms. We agitate with rotary brushes and pull the loosened material out under negative pressure with a HEPA filtration unit from Abatement Technologies. This is the difference between cleaning that removes debris and cleaning that just knocks it around.
Air Duct Inspection in Corte Madera
Air duct inspection in Corte Madera is the smart first step if you’re not sure whether your ducts actually need cleaning. We run a video camera through the supply and return runs and show you what we find, in real time. No vague talk about “you had some buildup.” You’ll see the actual condition inside your ducts and we’ll tell you honestly whether cleaning is worth it or whether you’re fine for another year or two. A camera inspection in Corte Madera typically costs $150 – $250, and it’s credited toward the cleaning if you proceed.
At a split-level home off Tamalpais Drive in the Chapman Park area, our tech ran a camera inspection and found the return duct coated in a damp gray film with lint packed around the air handler. We set up negative pressure with a HEPA filtration unit, used agitation tools on the supply and return runs, and cleaned the blower motor bay. Afterward the homeowner had before-and-after photographs of their own ducts showing the source removal. The system’s MERV rating was upped one step, and we agreed a flat price per system before we started, with no per-vent charges.
What a Camera Inspection Shows
The camera sees things no amount of looking at a vent cover will reveal: damp film on duct walls, fine silt accumulation, mold growth in the return, pest debris, and disconnected joints. In Corte Madera homes, the two most common findings are damp silt in the return run and fine Marin dust coating the supply branches.
When Inspection Is All You Need
If we inspect and find your ducts are clean, we’ll tell you that. Straight up. You pay for the inspection and nothing else. We’ll also give you specific advice on how long you can reasonably wait. That’s the straightforward answer most homeowners actually want, and it’s the one we give.
Common Air Duct Cleaning Problems We See in Corte Madera Homes
- Damp silt packed into return ducts. Because Corte Madera sits on the marshland edge, many crawlspaces hold seasonal moisture, and that fine silt gets drawn into return runs. Return ducts here need source removal, not a quick pass.
- Pest debris and old filter dust. Rats, mice, and birds find their way into vented crawlspaces under Corte Madera homes, especially older ones. We regularly find nesting material and droppings in supply runs, which a camera inspection will confirm.
- Marine-layer moisture film on duct surfaces. Richardson Bay’s humidity leaves a clammy film on duct walls, especially in spring and early summer. That’s why HEPA filtration and negative pressure matter more here than in drier inland cities.
- Disconnected or leaking duct joints. Older Corte Madera homes often have metal duct runs with joints that have pulled apart over time. We’ll flag any we find and give you a written price for the repair before doing the work.

Every three to five years for most Corte Madera households.

Call (737) 727-2314 for a free estimate – we’ll tell you straight whether you need it now or not.
Per system. One flat price for the entire system, written down and agreed before we start. We never quote per vent.

In Corte Madera, a full system cleaning runs $450 – $850 for a typical single-family home, and that’s the number you’ll see in writing.
We run Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for extraction, and Abatement Technologies containment units where needed.

We don’t promise same-day service because we don’t schedule jobs we can’t do properly. Tight crawlspace access in many Corte Madera homes needs a two-person crew, and we’d rather give you an honest first available slot than rush and do a partial job. A live person answers the phone 24/7 and will give you the earliest real appointment. Call (737) 727-2314 and you’ll speak to someone who can book you today.
It can help allergies by removing the buildup that recirculates through your home, especially the damp silt and pest debris we commonly find in Corte Madera return ducts. But it’s not a promise and we won’t pretend otherwise. A clogged coil or badly leaking ductwork drives energy bills up more than dirty ducts do, and we’ll tell you if we find either. For allergy relief, we often recommend a better Aprilaire or Honeywell filtration setup. Call (737) 727-2314 and we’ll give you an honest read on what’s worth doing and what isn’t.
