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 Palo Alto
Air duct cleaning in Palo Alto typically costs $395 to $750 for a standard single-system home, with larger floor plans and heavier buildup pushing toward the upper end. Most jobs wrap up in three to six hours, depending on how many returns and supplies your system has. We’re the team Palo Alto homeowners call when they want a written price before any work starts, a live arrival window they can track, and before-and-after photos of their own ducts. Call (737) 727-2314 and Omar or a member of the team will set you up with a free estimate.
We know Palo Alto’s streets, not just from GPS but from pulling into driveways off Middlefield, Embarcadero, and Foothill Expressway. That familiarity matters because this city’s housing stock changes block by block. A 1950s rancher in Midtown needs a different approach than a 1990s remodel in Crescent Park. Both are air duct jobs, but the ductwork itself tells a different story once we’re inside.
Why Cardinal Air Duct Cleaning Is Palo Alto’s Preferred Air Duct Cleaning Company
Part of the Relay Home Co. family founded in 2005, Cardinal operates each location independently but under The Relay Standard: a live trackable arrival time, before-and-after photo documentation, and a digital invoice you can pay from your phone. That’s the experience Palo Alto homeowners have told us they were missing from other duct cleaners. You know our technician’s name before they open the door. They arrive in uniform, background-checked, carrying professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. Not a shop-vac strapped to a truck.
Our reputation in Palo Alto has been built around one thing: the written price handed to you before a single duct is touched. It doesn’t change at the door. The 365-Day Done Right Promise backs every booking for a full year. If the work isn’t right within 365 days, we return and correct it at no charge. That’s not a promotion. It’s standing policy, no exceptions.
Our relationship with Palo Alto isn’t new. We see the same air quality issues repeat across Barron Park, Old Palo Alto, and Downtown North: decades of dust packed into retrofitted duct runs that were never cleaned by the previous owner. That’s our bread and butter here.
HVAC Duct Cleaning in Palo Alto
HVAC Duct Cleaning in Palo Alto means pulling accumulated dust, pet dander, construction debris, and whatever else has settled inside your supply and return lines out of your home rather than letting it cycle back through your living room. In a city where so many homes have been remodeled or added onto over the decades, we regularly find drywall dust and sawdust from past renovations still sitting in the ductwork. A full HVAC duct cleaning for a typical Palo Alto home runs $395 to $750.
What the process involves: we hook a Nikro HEPA-rated negative pressure vacuum to your system, agitate each run with rotary brushes, and collect debris at the source. Negative pressure means the loosened debris goes straight into the vacuum, not back into your living room. Every job includes a camera inspection so you can actually see what’s inside before and what’s left after.
Supply and Return Duct Cleaning
Most older Palo Alto homes have a mix of original galvanized supply ducts and newer flex returns that were added during a remodel. These run differently. Supplying air under pressure behaves differently than returning air under suction. We clean both, but we treat them as distinct jobs, which is why we price per system, not per vent.
Full System Cleaning with Video Inspection
A full system cleaning adds the air handler and blower motor, which many companies skip. In Palo Alto homes where HVAC equipment sits in tight attic spaces or closet cabinets, debris collects on the blower wheel and reduces airflow. We camera every job before and after, and the photos are yours. If you don’t see a difference, the 365-Day Done Right Promise applies.
Vent Cleaning in Palo Alto
Vent cleaning in Palo Alto overlaps with duct cleaning, but for many homeowners it’s about the symptom they notice first: dust accumulating on furniture within days of wiping it down, or a musty smell when the system kicks on. That’s usually your vent registers and the first few feet of duct behind them coated in pet hair and household dust. A vent-only cleaning with register removal, agitation, and HEPA extraction runs $180 to $300 depending on how many registers your home has.
Register and Boot Cleaning
The boot is the metal box directly behind your wall or floor register. In Palo Alto kitchens, we often find grease film mixed with dust that’s hardened inside the boot. That’s a restaurant smell that never goes away on its own. We remove the register, agitate that section, and extract everything with the vacuum running.
Return Vent and Grille Cleaning
Return vents in Palo Alto’s older homes are frequently undersized for the retrofitted systems they’re connected to. A single large return under a hallway is common in Midtown and Professorville bungalows. That one register is doing the work of three. When it clogs, the whole system starves. We’ll clean it and, if the camera shows restriction, we’ll tell you plainly what we’re seeing.
Trusted Brands We Service in Palo Alto
We’re not tied to any one manufacturer, but our equipment fleet is built around names the commercial restoration industry uses: Rotobrush for rotary agitation, Nikro for HEPA vacuum extraction, and Abatement Technologies for containment. We also work on systems paired with Honeywell filtration and Aprilaire media filters, which are common in Palo Alto’s newer construction. Since our crews serve the Bay Area daily, we carry standard filter sizes and replacement components locally rather than waiting on a shipment. That means less back-and-forth on most jobs in Palo Alto.
We also service and clean duct systems in homes built around those brands. If you have an Aprilaire filter housing or a Honeywell electronic air cleaner, we’ll inspect and clean the rack during the visit and let you know the filter’s actual condition. We won’t sell you a replacement because a coupon says it’s time.
Common Air Duct Cleaning Problems We See in Palo Alto Homes
- Debris recirculation after a cheap cleaning. A Palo Alto homeowner hires a company that runs a brush through the supply side and skips the return. Two weeks later, dust is back on the furniture. The debris never left; it just moved around.
- Mixed duct materials complicate cleaning. Original galvanized pipe and newer flex duct respond differently to agitation. Too much aggressive brushing on an old flex connector can tear it. Our techs adjust their tools per run, and they’re trained on Palo Alto’s typical mixed systems rather than cookie-cutter new construction.
- Crushed or restricted flex connectors behind walls. We’ve opened return inlets in Palo Alto to find flex duct pinched behind knee walls or attic beams. The restriction starves airflow and the system pulls dust from wherever it can. A camera inspection catches this before we touch anything.
- Construction dust from renovations. Homes in Old Palo Alto and Community Center are renovated with some regularity. Drywall sanding without sealing the returns leaves gypsum dust inside the ducts. That dust circulates for years. Our extraction removes it, but it takes the right HEPA vacuum to do it properly.
Pricing for Air Duct Cleaning in Palo Alto, CA
We price per system, not per vent. A standard single-system home in Palo Alto with one furnace and one air handler runs $395 to $750. That’s the whole job, not a teaser. Larger floor plans in Crescent Park or homes with two separate systems push toward $850 to $1,100. Vent-only cleaning starts around $180 to $300. Every quote is written and handed to you before we start. If the scope changes when we get inside, you approve the change in writing before any extra work happens.

FAQs About Air Duct Cleaning in Palo Alto
For most Palo Alto homes, every three to five years is honest. If you’ve remodeled, kept pets indoors, or live next to a major road like El Camino Real or Foothill Expressway, lean toward every two to three years. If your system was just installed and you don’t have pets or allergies, five to seven years is fine. We’ll tell you if you don’t need it yet. Call (737) 727-2314 and ask for a camera inspection first; the inspection happens before any cleaning quote.
Per system, always. A written quote covers the entire system: supplies, returns, air handler, and blower motor for the range we gave you. No per-vent add-ons at the door. If a Palo Alto tech from another company starts pricing per vent, ask why. The job is the system, not a grille count.
We run a camera into your ducts before cleaning and after. You get both sets of photos sent to your phone before the tech leaves the driveway. That’s the before-and-after proof of your own ducts, not a stock image. In Barron Park recently, Omar’s tech showed a homeowner the crushed flex connector behind a knee wall that was causing dust to recirculate, then photographed the same section after clearing it. That’s the standard on every job.
Because real cleaning takes a half day and crews are booked in advance during spring and fall when HVAC use spikes across the Bay Area. Same-day promises usually mean rushed work that skips the air handler or blower motor. We schedule a specific arrival window you can track live, and we never send a tech before a written price is agreed. Call (737) 727-2314 for the next open slot.
Yes. If the camera inspection shows no significant buildup and no signs of contamination, we’ll say so and recommend you save the money. Duct cleaning isn’t preventative maintenance like changing filters; it’s remediation. Some Palo Alto homes with newer ductwork simply don’t need it yet. We’d rather tell you that than sell you a service. That’s the whole point of the inspection.
