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 Orinda
Air duct cleaning in Orinda typically runs $450 – $850 for a full residential system and $1,200 – $3,500 for commercial jobs, with most homes completed in a single visit. We’re Hollis Air Duct Cleaning, and our crews work the Orinda hills regularly – off Moraga Way, along Camino Pablo, and throughout the canyon neighborhoods where hillside lots and shared-building complexes create duct access challenges flatland crews don’t face. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the technicians who arrive at your door know Orinda’s housing stock: the 1960s ranchers with original galvanized trunk lines, the split-levels retrofitted with flex-duct in the 1990s, and the multi-unit stacks where one clogged dryer vent chase serves several units at once. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Orinda’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning team has built a reputation in Orinda by showing up inside the quoted window, pricing every job in writing before we touch equipment, and leaving the site clean. That’s The Garrison Standard, and it’s how every independently owned Hollis location operates.
Orinda homeowners call us back because our technicians are background-checked and uniformed – you know who’s walking into your home before they arrive. Our 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule.
We know the local terrain. A technician running calls off Moraga Way and Camino Pablo often finds heat registers clogged with a mix of oak leaves and fine ash from the 2020s wildfire seasons, a pattern that never shows up in flatter, less-wooded Bay Area towns. That local knowledge changes how we approach the job.
Commercial Air Duct Cleaning in Orinda
Commercial Air Duct Cleaning in Orinda covers office buildings, retail spaces, medical clinics, and multi-unit residential complexes where shared HVAC systems move air through dozens of rooms from a single rooftop or basement handler. In Orinda, commercial jobs typically range from $1,200 for a small professional office to $3,500 for larger multi-unit buildings with complex duct networks. Most Orinda commercial clients need service every 2 – 3 years, though buildings near active construction or with high occupancy turnover may need annual attention.
Multi-Unit and HOA Scheduling
Orinda’s hillside condo complexes and shared-building lots often have restricted parking, narrow access drives, and HOA rules that limit when work can happen. We coordinate with property managers to stage equipment during approved windows and protect common areas during the job.
Rooftop and Basement Handler Access
Many Orinda commercial buildings have handlers tucked into tight mechanical rooms or on rooftops with limited ladder access. Our crews carry the right rigging for these setups and document condition with video inspection before and after cleaning.
Air Duct Cleaning Services in Orinda
Air Duct Cleaning Services in Orinda address the specific conditions this town’s geography creates: steep, wooded canyons that pull in douglas fir needles, oak pollen, and wildfire ash; 40 – 50 year old galvanized trunk lines with internal corrosion; and flex-duct retrofits where debris gets lodged in crushed runs. A typical full residential system cleaning in Orinda runs $450 – $850, depending on system size, duct material, and accessibility. Most single-family homes are completed in one visit.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the handler. In Orinda’s older homes, we often find return registers packed with oak leaves and ash that have been recirculating for years. We clean both sides of the system, not just the visible vents.

Video Inspection and Documentation
Our technicians use camera inspection to show you what’s inside your ducts before we start and what we’ve removed when we’re done. In Orinda’s hillside multi-unit buildings, this documentation is often required by HOA boards and property managers.

Trusted Brands We Service in Orinda
We run professional-grade equipment, not hardware-store gear. Our rotary brush systems come from Rotobrush, our negative-air machines from Nikro, and our filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use in hospitals and schools. For Orinda customers, that means we can source replacement filters, media, and sealing materials without long lead times. If your system uses Honeywell electronic air cleaners or Aprilaire media filters, we stock the common sizes and can install them during the same visit.
Common Air Duct Cleaning Problems We See in Orinda Homes
- Wildfire ash and oak debris in return registers. The Diablo Winds push smoke and ash from surrounding East Bay hills directly into Orinda’s canyon neighborhoods each fall. Combined with spring oak pollen, this creates seasonal loads that standard fiberglass filters can’t catch. We find this material packed into low-lying returns in homes off Camino Pablo and throughout the Moraga Way corridor.
- Internal corrosion in original galvanized trunk lines. Most Orinda homes are mid-century to 1970s ranchers and split-levels with galvanized steel ductwork now 40 – 50 years old. The internal corrosion isn’t visible from the outside, but it creates airflow restriction and particulate shedding that circulates through the house.
- Crushed flex-duct runs trapping debris. Retrofit flex-duct installed in tight hillside crawlspaces gets crushed by settling or rodent activity. Contractors who skip negative pressure and source removal just vacuum the registers while the real debris stays lodged in these collapsed runs.
- Shared dryer vent lint pathways in multi-unit stacks. Because so much of Orinda’s housing sits in hillside multi-unit complexes and shared-building lots off Moraga Way, a single duct cleaning job here often means chasing one clogged dryer vent lint pathway through a stacked chase that serves several units at once – something you’d never encounter in flat, single-family Danville.

FAQs About Air Duct Cleaning in Orinda
A typical full residential system cleaning in Orinda runs $450 – $850, and commercial jobs range from $1,200 – $3,500 depending on building size and duct complexity. The price is written down before any work starts and does not change at the door. Call (361) 326-5060 for a free estimate.
Low teaser quotes often use per-vent pricing that balloons once the technician is inside, or they skip essential steps like negative pressure and source removal. We charge one flat price per system, use Rotobrush and Nikro professional equipment, and include video documentation. The cheap quote becomes expensive when you have to hire someone else to do it right.
We provide before-and-after photos from our camera inspection, and we run the system with you after cleaning so you can feel the airflow difference. Our technicians also show you the debris collected in the HEPA-filtered containment unit. In Orinda’s multi-unit buildings, we provide written documentation for HOA records.
Most Orinda homes need full duct cleaning every 3 – 5 years, but homes in the canyon neighborhoods near heavy oak canopy or those affected by wildfire smoke may need it every 2 – 3 years. Homes with original galvanized trunk lines over 40 years old should be inspected annually for internal corrosion and joint leakage. Call (361) 326-5060 and we’ll recommend a schedule based on your specific location and system.
Extended dryer times usually mean lint buildup in the vent pathway, which is especially common in Orinda’s hillside multi-unit complexes where one stacked chase serves several units. This isn’t just an efficiency problem – it’s a fire risk under the town’s Wildland-Urban Interface building rules. Our dryer vent cleaning runs $150 – $250 for single units, and we inspect the full pathway including shared sections where accessible. Call (361) 326-5060 to schedule.
