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 Concord
Air duct cleaning in Concord typically runs $350 – $650 for a whole-home system and most jobs are scheduled within a few days, not weeks. We’re the Concord crew homeowners call when they want the price in writing before we touch anything.
Our dispatch team coordinates from the San Francisco Bay Area office, but the trucks that roll to Concord know the difference between a 1965 ranch in Sun Terrace and a new build off the BART corridor. That matters because the ductwork in those two homes needs completely different approaches. We’ve been part of the Garrison Partners family since 2004, and our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we come back and make it right at no charge. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Concord’s Preferred Air Duct Cleaning Company
Concord homeowners don’t need another coupon in the mailbox promising a $79 whole-house special. They’ve seen how that ends: a technician who finds “mold” that wasn’t there, or a bill that triples once the van is in the driveway. We don’t work that way. The price is written down before any work starts, and it does not move at the door.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. That’s The Garrison Standard, and it’s how every independently owned Hollis location operates. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
We’ve built our reputation in Concord on showing up, pricing honestly, and leaving the site clean. The 365-Day Done Right Promise means if something we cleaned or repaired fails within a year, we return and fix it at no charge, including a free second visit. That’s not a slogan. It’s in writing on every job.
Vent Cleaning in Concord
Vent Cleaning in Concord means more than brushing off the grille covers. We remove each supply and return register, agitate the duct walls with rotary tools, and extract debris under negative pressure using HEPA filtration. Most Concord homes need this every three to five years, though homes near the Diablo wind corridors or with original 1960s ductwork may need it sooner. A typical residential vent cleaning in Concord runs $350 – $550 for a standard system.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In older Concord neighborhoods, we often find these partially blocked by decades of accumulated dust, pet hair, and construction debris from prior renovations. Our Rotobrush rotary system breaks that material loose so the Nikro negative-air machine can pull it out.
Return Vent Deep Cleaning
Return vents draw air back to the handler. They’re the first entry point for dust and pollen, especially during Concord’s dry summer months. Many Sun Terrace homes still have the original rock-catcher grilles with no real filtration behind them. We clean the full return run, not just the visible grille.
Air Duct Repair in Concord
Air Duct Repair in Concord is where most of our calls actually end up, because cleaning alone won’t fix a crushed flex run or a disconnected plenum. We inspect with a video camera first, then quote the repair in writing before touching anything. Typical repairs in Concord range from $200 – $450 for reconnection and sealing, up to $800 – $1,400 for full flex-duct replacement in multiple runs.
Flex Duct Reconnection and Sealing
The foil-tape connections on 1960s – 70s flex duct fail after decades of heat cycling. We cut back to solid material, reconnect with new flex and proper mastic sealing, and test static pressure at the air handler to confirm the fix.
Crushed or Collapsed Run Replacement
In Sun Terrace and Concord Park, we regularly find flex duct that has been crushed against joists or sagging so badly it traps debris. Surface cleaning misses what’s packed in those collapsed sections. We replace the damaged run and support it correctly so it stays open.
Trusted Brands We Service in Concord
We carry professional-grade equipment from Rotobrush and Nikro, and stock filtration products from Honeywell, Aprilaire, and Guardsman. For Concord homeowners, that means we don’t have to order parts and come back next week. If your system needs a new media filter, a UV-light upgrade, or sealed duct access panels, we typically have what fits on the truck. Our technicians train on the same Abatement Technologies negative-air systems used in commercial buildings, so your home gets that level of extraction and containment.
Common Air Duct Cleaning Problems We See in Concord Homes
- Crushed flex duct in Sun Terrace and Concord Park. The original foil-taped flexible runs sag between joists over fifty years, then get packed with debris and rodent caches. A standard brush cleaning won’t open them back up.
- Zero filtration on returns. Most 1960s – 70s Concord homes still run the original rock-catcher grille with nothing behind it. Fine dust and pollen from Diablo wind events goes straight into the system and back out the supplies.
- Disconnected plenums in crawl spaces. Ground moisture isn’t Concord’s main problem, but temperature swings in unconditioned crawl spaces degrade tape and mastic. We find supply plenums hanging open, blowing conditioned air under the house.
- New BART-corridor infill with sealed hard duct. These systems need camera inspection and low-agitation protocols. A standard Rotobrush pass can’t navigate the tight bends, and aggressive cleaning can damage the sealed joints.

FAQs About Air Duct Cleaning in Concord
Because the original 1950s – 70s flex duct in neighborhoods like Sun Terrace and Concord Park has reached end of life. The foil tape crumbles, the inner liner tears, and the insulation sags. We start with a camera inspection, and about half the time we find damage that makes cleaning pointless until we reconnect or replace the run. We quote both options in writing before proceeding. Call (361) 326-5060 for a free inspection.
No. New infill near the Concord BART station uses tightly sealed hard duct with access panels designed for maintenance. Our standard Rotobrush pass won’t navigate those systems effectively. We use camera inspection and low-agitation tools, sometimes with compressed-air whips instead of rotary brushes, to clean without damaging the sealed joints. The protocol is different, and so is the pricing. Call (361) 326-5060 and we’ll ask about your home’s age and system type when we schedule.
Rodent droppings, acorn caches, and crushed flex packed with debris. In Sun Terrace, our tech pulled a sagging foil-taped flex run off a 1968 ranch’s air handler and found it crushed against a joist, packed with acorn shells and roof-rat droppings. After source removal with agitation tools under negative pressure and HEPA filtration, we reconnected the run with new flex and sealed the plenum. The customer’s “dust smell” at the registers disappeared and static pressure at the blower motor dropped back into range. Call (361) 326-5060 if you smell something off when the system runs.
Concord’s hot, dry summers and mild, wet winters mean ducts rarely see humidity-related mold, which is common in coastal markets. The dry air and Diablo winds drive fine dust and pollen deep into systems, especially in homes with minimal filtration. Most Concord homes benefit from cleaning every three to five years, but homes near open hills or with original rock-catcher grilles may need it every two to three. Call (361) 326-5060 and we’ll assess your specific setup.
If the smell is from accumulated dust and debris in the ductwork, yes. If it’s from a dead rodent, mold in the coil pan, or a disconnected plenum blowing crawl-space air, cleaning alone won’t fix it. We inspect with a camera first to identify the source. In Concord’s older neighborhoods, we often find both debris and a disconnected or crushed run contributing to the odor. We quote the full fix in writing before starting. Call (361) 326-5060 for a free estimate.
