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.
Air Duct Cleaning Company in Piedmont, CA
Air duct cleaning in Piedmont, CA typically costs $450 – $850 for a whole-home system and often reveals surprises that don’t exist in newer cities: original gravity-furnace remnants, asbestos-wrapped transite ducts left in crawl spaces, and retrofitted ductwork squeezed through 1920s framing. We’re Hollis Air Duct Cleaning, and we’ve learned that Piedmont jobs require a different inspection routine than standard suburban work. Our crews carry asbestos-awareness protocols and compact rotary brush systems from Rotobrush specifically for the tight joist bays and shallow attics common here. Call (361) 326-5060 for a free estimate.
Why Piedmont Homes Are Different
Piedmont is an entirely residential city where most homes were built before 1940, originally heated by gravity furnaces with no ductwork at all. When forced-air systems were retrofitted decades later, installers often ran flexible duct through original redwood floor joist bays or tucked it into uninsulated attics with minimal clearance. That means our technicians frequently work in spaces where a standard negative-air machine won’t fit, and where every turn risks crushing a 90-year-old lath-and-plaster ceiling from below.
The local climate adds its own layer. Piedmont sits in the East Bay hills where marine layer fog rolls in overnight, pushing damp air through attic vents and into ductwork where insulation is thin or missing. Oak and eucalyptus pollen from the surrounding hills collects in those same shallow attic ducts year-round. And because Piedmont maintains its own building department with strict design-review and tree-protection rules, any new duct routing or exterior penetration requires permits that neighboring Oakland or Emeryville might not demand. We’ve learned to check the original permit history before we quote, not after we arrive.
Then there’s the legacy material. Original octopus gravity furnaces were often replaced with forced-air units, but the old asbestos-wrapped ducts or transite pipes were simply abandoned in crawl spaces. Our crews are trained to identify and properly handle these materials before any cleaning or sealing begins. Disturbing legacy asbestos without the right protocol turns a routine job into a hazardous-waste event.
Our Main Piedmont Services
Most Piedmont homeowners call us for one of three jobs, each shaped by the city’s unique housing stock and climate conditions.
Air Duct Cleaning in Piedmont
Our Air Duct Cleaning in Piedmont starts with a camera inspection because we need to know what’s in your joist bays before we commit to equipment. We use Rotobrush rotary brush systems for the tight retrofitted ducts common in Craftsman and Tudor homes, paired with Nikro negative-air machines when attic space allows. Where we find moisture staining from marine-layer intrusion, we flag it for you before we clean so you’re not paying to scrub ducts that need sealing first.

Dryer Vent Cleaning in Piedmont
Dryer vent runs in Piedmont’s older homes are often longer and more convoluted than code would allow today, routed through original exterior walls with multiple elbows. Our Dryer Vent Cleaning in Piedmont includes airflow testing before and after, because a partially blocked vent in a long run creates back-pressure that strains the dryer and builds lint at every turn. We carry extension rods and high-torque brushes specifically for these extended configurations.

Duct Sealing in Piedmont
Given how many Piedmont systems were retrofitted into spaces never designed for ductwork, leakage is often the real problem, not dirt. Our Duct Sealing in Piedmont targets the gaps at joist-penetration points and the seams where flexible duct meets original plaster. We use duct sealing mastic and mechanical fasteners, not tape that degrades in damp attic conditions, and we test with a duct blaster to prove the seal before we leave.
