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 HVAC Cleaning Across Piedmont
HVAC cleaning in Piedmont typically runs $395 – $695 for a complete system on a standard three-bedroom home, and most jobs take four to six hours from setup to final photos. We’re not the cheapest quote you’ll get in the 94611 zip code, and that’s intentional: we do the full job, not a quick pass with a shop vac. Our crews know Piedmont’s streets and driveways well enough that we don’t need to ask for directions once we’re past Grand Avenue. If you want a real diagnosis of what’s inside your ducts, call (737) 727-2314 and we’ll schedule it.
The HVAC Cleaning work we do in Piedmont is disassembly-heavy and camera-guided. That matters here more than almost anywhere else in the East Bay, and I’ll explain exactly why below.
Why Cardinal Air Duct Cleaning Is Piedmont’s Preferred HVAC Cleaning Company
Piedmont homes throw us curveballs that tract housing never does. On a cul-de-sac off Moraga Avenue, the duct system might be a 1935 gravity furnace conversion. Two blocks over on Highland Avenue, it’s a 1970s forced-air retrofit spliced into the original crawlspace. You cannot price that per vent and be honest about it, which is why we quote one flat price per system after looking at the job. Piedmont homeowners tell us they appreciate not getting a surprise line item for “additional vent beyond quoted count.”
We’re part of the Relay Home Co. family, founded 2005, and every Piedmont job is held to The Relay Visibility Guarantee. That means you get a live trackable arrival window, before-and-after photos of your own registers and coil, and a digital invoice you can pay from your phone. Omar Haddad leads our Bay Area team, and the tech who shows up at your door in Piedmont is background-checked, uniformed, and carrying professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. You’ll know their name before they ring the bell.
AC Coil Cleaning in Piedmont
AC Coil Cleaning in Piedmont is one of the most skipped services on pre-1950 homes, and it’s also the one that saves real money on summer electric bills and compressor life. The evaporator coil sits inside the air handler, and when it’s coated with dust and hair, the system runs longer to hit the same temperature. In a hillside climate like Piedmont’s, where summer days swing from cool fog to 85-degree afternoons, a dirty coil makes the whole house feel clammy and muggy even when the thermostat says it’s fine.
The Coil Cleaning Process
We pull the air handler panel and inspect the coil before touching anything. On a 1940s colonial near Wildwood Avenue, that often means finding decades of plaster dust and pet hair baked onto the fins. We clean it with professional-grade products and then treat the coil to slow future buildup. The difference in airflow is immediate, and we show you the before-and-after photos yourself.
What Piedmont Homeowners Pay
Standalone evaporator coil cleaning in Piedmont runs $180 – $340 depending on access and how heavily the coil is fouled. If it’s done as part of a full HVAC cleaning, the coil work is bundled into the system price and saves you money versus booking it separately. Condenser coil cleaning on the outdoor unit is an additional $120 – $190, and it’s worth doing in Piedmont because so many condensers sit under oak and eucalyptus trees that shed directly into the unit.
AC Cleaning in Piedmont
AC Cleaning in Piedmont is not the same as duct cleaning, and it’s worth being precise about the difference. This is the full cleaning of the mechanical parts that move air: the blower motor, the blower wheel, the evaporator coil, the air handler housing, and the condensate drain pan. On Piedmont’s older systems, these components are often original or decades old, and they collect a grime that reduces airflow as surely as a dirty duct does.
Blower and Air Handler Cleaning
The blower wheel is what you hear when the system runs. On a 1928 Mediterranean on Crocker Avenue, our tech recently opened the air handler and found the blower motor caked with drywall dust and pet hair from a prior remodel. That’s not rare in Piedmont; the city’s remodels are constant, and the ductwork rarely gets sealed off while walls come down. We use negative-pressure extraction, which means the loosened debris goes straight into a HEPA-filtered vacuum, not back into your living room.
When Piedmont Homes Need It
If the system has run for more than eight years without a mechanical cleaning, it needs it. If you renovated, sanded floors, or did drywall work while the furnace fan was running, it needs it sooner. A full AC cleaning of the blower, coil, and air handler housing runs $290 – $450 when booked as part of the whole HVAC cleaning, and we hand you a written price before a single panel comes off.
Trusted Brands We Service in Piedmont
Piedmont’s housing stock spans nearly a century of furnace and AC brands, and that’s not a problem for our techs. We service and clean Ruud, Carrier, Trane, Bryant, Lennox, York, Goodman, and the older Rheem and Day & Night units that are still running in many homes east of Oakland Avenue. We stock common filters and replacement parts for these brands and use Guardsman filtration products and Aprilaire filter media when a Piedmont customer wants upgraded filtration during the cleaning. No special-order delays, no second trip just to bring a part.
Common HVAC Cleaning Problems We See in Piedmont Homes
- Retrofit ductwork that was never sealed. Many Piedmont homes had forced-air heat added in the 1950s through the 1980s, and those duct connections were never properly sealed. We find disconnected joints and open gaps behind plaster walls on a regular basis, and a camera inspection is the only way to locate them.
- Remodel dust packed into the blower and coil. Piedmont has one of the highest renovation rates in the East Bay. Drywall dust, floor sanding residue, and general construction debris get pulled through the return duct and caked onto the blower wheel and evaporator coil.
- Crushed or collapsing duct runs under older homes. Pre-1950 crawlspaces are tight, and duct runs that were installed decades ago often get crushed by foot traffic, seismic settling, or plumbing work that came after. A cleaning that skips camera inspection simply misses this.
- Condensate drain clogs and microbial growth. Piedmont’s warm inland afternoons and cool nights create condensation inside the air handler. When the drain line clogs, the pan backs up and microbial growth starts. We clean and clear the drain line as part of every full HVAC cleaning.

FAQs About HVAC Cleaning in Piedmont
If your system has run more than eight years without a mechanical cleaning, you’ve renovated while it was running, or you can smell dust when the heat kicks on, it’s time. The most reliable test is a camera inspection of the supply ducts and a visual check of the blower wheel and coil. We do that inspection as part of every estimate, and if your system is genuinely clean, we’ll tell you and recommend you save your money. Call (737) 727-2314 for an honest assessment.
One flat price per system, always. Per-vent pricing is misleading on Piedmont’s irregular retrofit ductwork, where vent count says nothing about the length and condition of the hidden runs. We quote a single written price after seeing the job, and that number doesn’t change when the tech arrives.
Every five to seven years for a full system cleaning, and sooner if you’ve done major remodeling or have pets that shed heavily. Homes on busy Piedmont streets like Grand Avenue or Moraga Avenue pick up more particulate matter, but the biggest driver locally is renovation dust, not outdoor air. Newer homes with well-sealed ducts can go longer.
We set up negative-pressure containment with HEPA filtration, then agitate the duct interior with Rotobrush rotary brush tools to dislodge debris. The loosened material is pulled into a Nikro HEPA-filtered vacuum rather than blowing into your rooms. After that, we clean the blower, coil, air handler, and drain line, then run a camera through the ducts to show you the result. You get before-and-after photos of your own registers before we leave.
Yes, always. Every Piedmont job includes before-and-after photos of your own ducts, coil, and blower, taken with a camera so you can see the actual surfaces. That’s part of The Relay Standard, and it’s non-negotiable. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it applies to every booking without exception.
