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.
Fast, Reliable Air Duct Cleaning Across Napa
Air duct cleaning in Napa typically costs $395 to $690 for a full system on a standard 1,500 to 2,500 sq ft home, and the job takes half a day once our crew arrives. We say “once our crew arrives” because we won’t promise a same-day dash across the Bay Area just to book the call.

Call (737) 727-2314 for a free estimate.
Why Cardinal Air Duct Cleaning Is Napa’s Preferred Air Duct Cleaning Company
We are part of the Relay Home Co. family, founded 2005, and held to The Relay Visibility Guarantee on every job in Napa. That means a live trackable arrival window before we show up, a digital invoice you can pay from your phone, and a written price handed to you before work starts. No vague estimates, no four-hour arrival windows, no price that shifts once the van is in your driveway. Napa homeowners tend to be direct, and so are we.
Our technicians are background-checked and arrive in uniform, and they run Rotobrush rotary brush systems, Nikro HEPA-rated vacuums, and Abatement Technologies containment units. You’ll know the tech’s name before they ring the bell. Omar Haddad leads the team, and he holds every Napa job to the 365-Day Done Right Promise: if the work isn’t right within a year, we return and correct it at no charge. That applies to every booking without exception. For Air Duct Cleaning done with total visibility, this is the standard we operate by.
Air Duct Inspection in Napa
Air Duct Inspection in Napa is the step most homeowners skip, and it’s the step that catches what a routine cleaning never will. A camera inspection of your ductwork tells us whether the dust in your house is coming from normal buildup or from a separated trunk joint, a crushed return, or a rodent that found its way into the plenum. In Napa’s older homes, especially around downtown and the east side, original sheet-metal trunks with unsealed joints are common. Those gaps pull attic air and dust into your system no matter how many times you vacuum the registers. An inspection runs $149 to $249 as a standalone service, and the fee is credited toward full system cleaning if you book both.
Camera inspection of the trunk and branches
We run a high-resolution camera from the air handler down the main trunk and into the supply branches. We look for disconnects, corrosion, crushed flex runs, and buildup thickness. You see the footage in real time, on our tablet, before any cleaning begins.
Pressure and airflow check
If airflow feels weak in one part of the house, the problem is rarely the fan. It is usually a restriction or leak somewhere in the duct run. We check static pressure and airflow at the registers so we can tell you whether cleaning will solve the problem or whether you need a seal and repair conversation instead.
Residential Air Duct Cleaning in Napa
Residential Air Duct Cleaning in Napa means cleaning the supply side, the return side, the main trunk, and the air handler in a single visit. We run agitation tools through every reachable section under negative-pressure extraction, which means the loosened debris goes straight into the Nikro HEPA vacuum instead of back into your living room. For a typical Napa home, this runs $395 to $690 depending on square footage and the number of returns. We give you a written price before we start, and that price does not change at the door.
Full system cleaning, not register vacuuming
The cheap crews vacuum what they can see and call it done. That leaves the trunk and the air handler untouched, and the dust redistributes within weeks. We clean the full path: returns, supply runs, trunk, plenum, and the air handler cabinet. Before-and-after photos of your own ducts are included with every job.
Dryer vent runs in the same visit
Your dryer vent is separate from the HVAC system, which is why some companies skip it. We don’t. The lint you can reach at the trap is a fraction of what builds up inside the run, and that buildup is the leading contributor to home dryer fires. We add the dryer vent run for $75 to $125 when bundled with duct cleaning.
Trusted Brands We Service in Napa
We service and work alongside equipment from Honeywell, Aprilaire, and Guardsman filtration products, and we carry Guardsman filters and Aprilaire media with us on Napa calls. If your system uses a Rotobrush-cleaned duct network or an Abatement Technologies containment setup from a previous job, we’re familiar with it. Our equipment fleet includes Rotobrush brush systems, Nikro HEPA extraction, and Abatement containment units, so we are not walking in with a shop vac and a spray bottle. We carry common replacement filter sizes and can swap them during the same visit. This matters when your air handler is in a tight Napa crawlspace and you don’t want a second service call.
Common Air Duct Cleaning Problems We See in Napa Homes
- Drywall dust packed into ducts from a past remodel. Napa’s older homes have been through decades of kitchen and bath renovations, and the dust from drywall sanding settles into sheet-metal runs and stays there. A standard cleaning pulls it out; a register vacuuming never touches it.
- Unsealed joints on original sheet-metal trunks. Downtown Victorians and 1960s-70s east side tract homes share this issue. Gaps at trunk joints pull attic air and insulation into the system, which means dust returns even after a cleaning. Sealing those joints is part of the conversation we have on many Napa jobs.
- Crushed flex runs under the house. The flex duct installed in the 1980s and 90s gets flattened by critters, storage, or poor original installation. A crushed return starves the air handler and pulls dust from the crawlspace. Camera inspection shows exactly where it’s failing.
- Lint-clogged dryer vents at the wall or roof. The run is short or long depending on the laundry location, but every Napa home has one. If the flap at the exterior doesn’t open on its own during a cycle, that’s a sign. We rod and vacuum the full run, then show you the before-and-after photo.

FAQs About Air Duct Cleaning in Napa
Every five to seven years for most Napa homes, with two exceptions. Homes with heavy shedding pets, recent remodeling, or residents with serious allergies may need it every three to four years. Homes with sealed, clean ducts and no recent construction can go eight years or longer. If you don’t see dust buildup at the registers and your air quality is fine, cleaning may not be needed yet. Call (737) 727-2314 and we’ll tell you honestly whether a cleaning is worth it.
Per system, never per vent. The per-vent model is how companies bait a low quote over the phone and then inflate the invoice once the technician is inside. We quote one flat price per system, in writing, before work starts. That number does not change. Napa homeowners get the same commitment whether they’re in a 900 sq ft cottage off Jefferson Street or a 3,000 sq ft house in Browns Valley.
Agitation of every reachable supply and return run under negative pressure, plus cleaning of the trunk, plenum, and air handler cabinet. Our techs run Rotobrush agitation tools while a Nikro HEPA vacuum pulls the loosened debris out of the system. Before-and-after photos of your own ducts are included. If a company is only vacuuming registers, they are not cleaning your ducts. Call (737) 727-2314 to book the full process.
We don’t promise same-day service, and we won’t invent a dispatch time just to get the booking. Duct cleaning in Napa is a scheduled job, and doing it right takes a half day. What we do guarantee is a live trackable arrival window once the job is booked, so you’re never waiting on a four-hour block. Call (737) 727-2314 and we’ll get you the next available window, usually within a few days depending on the season.
Camera inspection catches separated joints, crushed flex, rodent entry points, and gaps at the plenum. A cleaning removes dust from the runs, but if the trunk has a gap near the air handler, dust will come right back. That’s the difference between treating a symptom and finding the cause. We saw this exact thing on a 1950s ranch off Linda Vista Avenue. The homeowner kept finding dust on the return registers days after each cleaning. Camera inspection showed a separated main trunk joint near the air handler. Our tech ran agitation tools through the supply and return ducts under negative pressure, pulled out a mat of drywall dust and old lint, then sealed the gap before reassembling. The dust stopped returning within two weeks, and the before-and-after photos made the call an easy one. Call (737) 727-2314 to schedule an inspection in Napa.
