Call (361) 326-5060

We’ve been in this trade since 2004, and Walnut Creek keeps us busy for reasons you won’t find in every California city. The oak woodlands surrounding town dump heavy spring pollen. Triple-digit summer days force AC systems to run hard for months. And after Diablo wind – driven wildfire events, fine ash works its way into return plenums and recirculates every time the blower kicks on. Then there’s the housing stock: thousands of 1960s and 1970s ranch homes with original ductwork, plus dense condo stacks downtown and along Ygnacio Valley Road where shared air handlers feed multiple units. Our Air Duct Cleaning crews know the difference between a routine dust removal and a building-wide source-removal job. That local knowledge matters when the goal is clean air, not just a clean vent cover.

Why Hollis Air Duct Cleaning Is Walnut Creek’s Preferred Air Duct Cleaning Company

We’re part of the Garrison Partners family, and every Hollis location operates under The Garrison Standard: arrive inside the quoted window, price in writing before touching equipment, complete the job by the book, and leave the site clean. In Walnut Creek, that standard gets tested by shared building systems, restricted parking downtown, and smoke residue that standard dust cleaning won’t touch. We meet it with background-checked, uniformed technicians and professional-grade equipment from Nikro and Abatement Technologies.

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. When you call (361) 326-5060, you talk to a human who can schedule your Walnut Creek appointment and confirm your written price before the truck rolls.

We know the local terrain. Crews carry extra hose length for downtown buildings where parking restrictions push vacuum trucks blocks from the curb. We camera-inspect vertical chases in condo stacks before agitation, because cleaning one unit’s ducts without tracing the shared pathway just redistributes ash and lint to neighbors. And we check return plenums for smoke odor before opening a single vent, a step that catches wildfire residue routine cleanings miss.

Commercial Air Duct Cleaning in Walnut Creek

Commercial Air Duct Cleaning in Walnut Creek covers office buildings, retail spaces, medical clinics, and multi-unit residential properties where the HVAC system serves more than a single household. These jobs typically run $800 – $2,500 depending on system size, access difficulty, and whether the building has a shared rooftop unit or individual package systems. We price commercial work by the system, not by the vent, with a written quote delivered before any equipment enters the building.

Multi-Tenant Buildings and Shared Air Handlers

Walnut Creek’s downtown and Ygnacio Valley Road corridor hold dense 1960s – 70s apartment and condo stacks where a single rooftop or closet air handler feeds multiple units. Dryer vents and return ducts share vertical chases. Cleaning one unit without tracing the shared lint pathway leaves the problem recirculating for every neighbor. Our crews map the full system with video inspection before source removal, then set up proper negative pressure at the correct access points.

Post-Smoke Event Commercial Recovery

After Diablo wind events, fine ash penetrates commercial filtration and settles in return plenums and flex duct runs. Standard cleaning agitates that ash back into the airstream. We use Nikro negative-air machines to maintain containment during agitation, followed by rotary brush contact cleaning and filtered downline capture. The goal is source removal, not redistribution.

Air Duct Cleaning Services in Walnut Creek

Air Duct Cleaning Services in Walnut Creek include full system cleaning of supply and return ducts, video inspection, dryer vent cleaning, and duct sealing with mastic for leaky joints. Residential pricing runs $350 – $650 for a complete cleaning of a typical single-family system, with older homes or heavy contamination at the higher end. Every job starts with a written price and ends with before-and-after photos of your own ducts.

Residential Duct Cleaning and Sealing

Much of Walnut Creek’s housing stock consists of 1950s – 1970s ranch homes with original rigid or flex duct systems that have never been professionally cleaned. Leaky joints in that original ductwork recirculate wildfire ash every AC cycle. We clean first, then seal accessible joints with mastic so the system holds its pressure and stops pulling attic or crawl space air into your supply.

Video Inspection and Documentation

We run camera inspection before and after agitation cleaning. You see what we see: ash buildup, pollen loading, or lint accumulation in the vertical chase. After a Diablo wind event, that documentation matters for insurance claims and for proving the job was done, not just invoiced.

Trusted Brands We Service in Walnut Creek

Our equipment roster includes Nikro negative-air machines, Rotobrush rotary brush systems, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock filters and replacement parts sized for the systems common in Walnut Creek’s 1960s – 1990s housing stock, so most filter upgrades happen same visit without a return trip. When a condo building off Ygnacio Valley Road needs a MERV 13 upgrade after smoke contamination, we carry the dimensions that fit the closet air handlers typical in those buildings. No waiting on a parts run to San Jose. No “we’ll come back next week.” The Garrison Standard means arriving prepared.

Common Air Duct Cleaning Problems We See in Walnut Creek Homes

• Shared condo and apartment stacks with untraced vertical chases. A single rooftop or closet air handler feeds multiple units, and the return duct runs through a common chase. Clean one unit’s supply and return without camera inspection of the common pathway, and you’ve just redistributed ash and lint to every neighbor on the stack.
• Downtown restricted parking forcing undersized equipment. Walnut Creek’s narrow alleys and permit zones push vacuum trucks blocks from the curb. Crews who improvise with short hose runs lose the static pressure needed for proper source removal. We plan access in advance and carry sufficient hose length to maintain negative pressure at the correct distance.
• Original 1960s ranch ductwork with leaky joints recirculating wildfire ash. Many Walnut Creek ranches still have their original rigid duct systems. The joints leak. Every AC cycle pulls attic air and wildfire ash back into the supply. Homeowners schedule a routine dust cleaning, but skip the plenum odor check that catches smoke residue. We check first.
• Heavy oak pollen loading in spring return ducts. The surrounding hills and woodlands produce pollen counts that standard fiberglass filters can’t stop. By June, return ducts in homes near open space are coated with a fine green-yellow film that restricts airflow and forces the blower motor to work harder.
