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 Piedmont
Air duct cleaning in Piedmont typically costs $380 – $620 for a full residential system, and a proper job takes most of a day on the early-1900s homes that define this city. We’re not going to quote you per vent, and we’re not going to “find” surprise buildup after we arrive. One flat price per system, written down and handed to you before any work starts. That’s how Cardinal Air Duct Cleaning has earned its place in Piedmont, and it’s why homeowners here keep our number: (737) 727-2314.
Piedmont isn’t Oakland flatland work. The streets off Highland Avenue, the 1920s Colonials past the Exedra, the steep lots around Blair Avenue, the wall-void returns in old Grand Avenue homes, every block here has its own quirks. Our crews stage on your driveway or a permitted parking block, set up HEPA filtration at the air handler, and get to the actual problem. You know the price before the equipment comes off the truck. You know the technician’s name before you open the door.
Why Cardinal Air Duct Cleaning Is Piedmont’s Preferred Air Duct Cleaning Company
The homes in Piedmont don’t have simple trunk-line duct systems like the newer housing down in Oakland. Many were built between 1905 and 1935, with original wall cavities repurposed as return chases, unlined and unsealed. That means plaster dust, lint, and whatever else settled in those voids decades ago is still moving through your system every time the blower kicks on. Most companies running a Shop-Vac attachment through your registers aren’t dealing with that. Air Duct Cleaning on these older Piedmont systems requires negative-pressure extraction and agitation tools that actually loosen decades of debris from wall-void returns.
Omar Haddad, who leads our team, has walked through enough of these Piedmont crawlspaces to know exactly what hides in a 1920s return chase. Our technicians are background-checked, uniformed, and carrying professional equipment: Rotobrush rotary brush systems for supply runs, Nikro HEPA vacuums rated for lead-safe and fine particulate capture, and Abatement Technologies containment units when a job requires more care. We’re part of the Relay Home Co. family, founded 2005, and every booking runs on The Relay Visibility Guarantee. That means a live trackable arrival time, before-and-after photos, and a written price before anything is touched.
Air Duct Inspection in Piedmont
Air Duct Inspection in Piedmont usually runs $99 – $150 for a camera walk-through of your supply and return runs, the blower compartment, and any wall-void return chases we can access. If you’ve just bought one of the older homes near Dracena Quarry Park or off Crocker Avenue and you don’t know what’s in the ducts, this is where you start. We run a snake camera through the system and show you what we find before recommending anything. When a home on Wildwood Avenue had a family sneezing for months despite a new filter, our camera inspection caught a return chase packed with plaster dust and a mouse nest. That’s the kind of thing you can’t see from the register.
Camera Inspection Before Cleaning
On older Piedmont homes, a visual inspection tells us whether you’re dealing with simple dust buildup or decades of debris that migrated through unlined wall cavities. Some systems from the 1920s still have original cloth duct tape or unsealed joints where the return air pulls from inside the wall itself. You can’t see that from the vent cover. The camera does in about 20 minutes.
When Inspection Turns Into a Recommendation
If the blower motor is coated in grey lint or the return chase shows heavy plaster dust, you’ll likely want a full system cleaning. Not every inspection does. Sometimes the ducts are dirty but safe to leave alone for another season. We’ll tell you straight, and we won’t fabricate a problem to sell a cleaning. If you’d like a second opinion after we leave, the photos are yours to keep. Call (737) 727-2314 to book an inspection.
Residential Air Duct Cleaning in Piedmont
Residential Air Duct Cleaning in Piedmont runs $380 – $620 for a typical early-1900s waterfront, the final price depending on the number of systems, access difficulty, and whether wall-void returns need interior agitation. We do not charge per vent. We quote the system, the whole system, in writing, before the first register is touched. For most Piedmont homes, that means a full day of work, not a 45-minute pass-through.
The process is source removal, not just brushing. We connect a Nikro HEPA vacuum to create negative pressure at the air handler, so loosened debris is pulled directly into the collection unit instead of blowing back into your living room. Then we agitate each supply run and return chase with mechanical tools. On homes near Grand Avenue with tight crawlspaces, we may need to set up an Abatement Technologies containment unit to keep plaster dust from migrating during the work. The result is air that actually moves cleaner, not just a receipt that says it does.
Supply and Return Duct Cleaning
Supply runs and return chases on old Piedmont homes collect different things. Supply ducts pick up dust, pet hair, and whatever falls into floor registers. Returns, especially the unlined wall-void chases common in 1920s construction, collect plaster dust, lint, and sometimes far worse. A mouse nest is not rare. We treat them separately, clean both, and show you the before-and-after photos from the camera at your own registers.
Blower and Air Handler Cleaning
The blower motor on a Piedmont home built in the 1920s or 30s has often never been cleaned. Once we have negative pressure established, we clean the blower wheel, housing, and any accessible evaporator coil. A coating of grey lint on the blower means the system is pushing less air than it should. Cleaning that compartment is part of the flat system price, never an add-on. Call (737) 727-2314 for a quote on your Piedmont home.
Trusted Brands We Service in Piedmont
We service and recommend filtration from Honeywell, Aprilaire, and Guardsman, and the homes here use them all. If your Piedmont system has an Aprilaire media cabinet or a Honeywell electronic air cleaner, we inspect it during the cleaning and let you know if the media is due. We stock common Guardsman and Aprilaire filters for Piedmont customers, so when we finish cleaning the ducts, we don’t hand you a recommendation to order something online. It’s already on the truck. Rotobrush and Nikro are what our crews run, and they’re maintained to handle the dust loads these old Piedmont homes throw at them.
Common Air Duct Cleaning Problems We See in Piedmont Homes
- Plaster dust in wall-void returns. Piedmont’s early-1900s homes often use unlined wall cavities as return chases, and decades of settling plaster, lathe dust, and debris collect inside. A standard brush-through doesn’t reach it. This is the single most common issue we see off Highland Avenue and Blair Avenue.
- Mouse and rodent activity in old ducts. The crawlspaces under 1920s Craftsman homes are not sealed to modern standards. We regularly find nests, droppings, and chewed flex connections in systems around Crocker Avenue and Dracena Quarry Park. HEPA containment is non-negotiable for these jobs.
- Lint migration from laundry rooms. Many Piedmont homes route the dryer vent near the air handler or shared return, especially in older utility rooms off kitchens. That lint gets pulled into the return and recirculates through every register. We check the dryer vent connection on every residential cleaning.
- Restricted staging and access on narrow streets. Parking on a narrow block off Grand Avenue or near the Piedmont Community Hall means our truck needs a driveway or permitted space. We plan for that before we schedule, and the setup time is built into your written quote, not added later as a surprise “access fee.”
Pricing for Air Duct Cleaning in Piedmont, CA
A standard residential system in Piedmont runs $380 – $620. A single-story 1920s home with accessible returns and a standard supply trunk usually lands near the middle of that range. Larger homes, second systems, or wall-void returns needing careful agitation push toward the top. Air duct inspection runs $99 – $150 and is credited toward the cleaning if you book within 30 days. Commercial jobs and full-system cleaning on older homes with multiple returns are quoted after a walk-through, but the same flat-price rule applies: one written number, before work begins, no per-vent math. Estimates are free, and a live person answers at (737) 727-2314.

FAQs About Air Duct Cleaning in Piedmont
Every 3 – 5 years is honest for most Piedmont homes. The older the house, the more frequently wall-void returns and unsealed joints accumulate plaster dust and lint. If you just bought a 1920s home and have no record of prior cleaning, do it once and set a baseline. If anyone tells you it should be done annually, walk away. Call (737) 727-2314 and we’ll tell you straight whether it’s worth doing now.
One flat price per system, written down before work starts. We don’t charge per vent, and we don’t add fees for “heavy buildup” once the technician is inside. Per-vent pricing is how bait-and-switch companies work in this trade. A low per-vent teaser becomes a large invoice fast. We quote the entire system, agree on it, and the number doesn’t move at the door.
Because you should see exactly what was inside the system and what it looked like when we finished. Every Cardinal booking includes before-and-after photos of your own ductwork, registers, and blower compartment, not stock images. We use a camera inspection before and after. If something wasn’t reached or a section needs follow-up, the photos show that too, and the 365-Day Done Right Promise covers the fix. That’s The Relay Standard.
It involves negative-pressure HEPA extraction at the air handler, agitation of supply and return runs, cleaning of the blower compartment, and a camera inspection at the end. It does not involve a 45-minute brush-through with a Shop-Vac attachment. On Piedmont’s early-1900s homes, we’re often working in crawlspaces and wall-void returns, so plan for most of a day. The written quote includes all of that setup. Call (737) 727-2314 for a realistic time estimate on your home.
Yes. Every residential cleaning includes a check of the dryer vent connection at the point where it ties into the system. Full dryer vent cleaning is a separate service, but if lint is migrating into your return or the vent is visibly clogged, we’ll show you on the camera and quote it on the spot. No surprise invoices, just a written price if you want the work done. Estimates come from a live person at (737) 727-2314.
