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 Bay Point
Air duct cleaning in Bay Point typically runs $350 – $650 for a whole-home system, with most residential jobs completed in a single visit. We’re the Bay Point crew from Hollis Air Duct Cleaning, and we know the split personality of this town’s ductwork: the postwar tracts and mobile homes on the bayside flats versus the newer subdivisions up in the hills. Our dispatch team coordinates from our San Francisco Bay Area office, and our trucks carry Rotobrush rotary systems and Nikro negative-air machines to both sides of town. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Bay Point’s Preferred Air Duct Cleaning Company
We’ve been working Bay Point homes since 2004 as part of the Garrison Partners family. That longevity means we’ve cleaned ducts off Port Chicago Highway, Bailey Road, and the hillside streets above Highway 4 enough times to know what we’re walking into before we park the van.
Our technicians follow The Garrison Code: arrive inside the quoted window, price the job in writing before touching anything, finish by the book, and leave the site clean. Every tech is background-checked and uniformed, so you know who’s coming through your door.
Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule.
Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal assurance; it’s printed on the invoice.
Air Duct Cleaning Services in Bay Point
Air Duct Cleaning Services in Bay Point cover the full removal of accumulated dust, debris, and microbial growth from your supply and return ductwork, using negative-air containment and mechanical agitation rather than surface sprays. A typical residential cleaning in Bay Point runs $350 – $550 for a standard single-system home, with larger or more complex systems reaching $650. Mobile homes on the flats often run toward the lower end but require specialized low-clearance equipment; hillside subdivisions with longer trunk-and-branch systems may run higher due to extended duct runs.
Residential Duct Cleaning
We clean the full supply and return network in Bay Point homes, from the main trunk lines to the branch ducts at each register. Our Rotobrush rotary brush systems scrub the interior surfaces while Nikro negative-air machines maintain suction, pulling dislodged debris through HEPA filtration so nothing resettles in your living space.

Commercial Duct Cleaning
Bay Point’s small commercial buildings, from the retail strips along Highway 4 to the industrial spaces near the waterfront, need scheduled cleaning that doesn’t interrupt operations. We price commercial systems after a walkthrough, with the written quote delivered before any equipment is moved inside.

HVAC Duct Cleaning in Bay Point
HVAC Duct Cleaning in Bay Point means cleaning the entire forced-air pathway: the furnace or air handler, evaporator coil if accessible, blower assembly, and all connected ductwork, not just the visible registers. A complete HVAC duct cleaning in Bay Point typically costs $450 – $650 for residential systems, with the higher end covering homes with multiple zones or extensive contamination. We use video inspection before and after to show you what was actually removed, not just what we claim happened inside the walls.
Supply and Return Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the unit. Both sides load up differently in Bay Point. Supply lines on the bayside flats often show that gray-black soot film from Delta wind and rail activity, while return ducts trap the larger debris your filter missed.
Full System Cleaning with Video Inspection
We run a camera through the trunk lines before we start and again when we’re done. You see the buildup. You see the clean metal. No guesswork, no trust-me language. The video file belongs to you.
Trusted Brands We Service in Bay Point
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for containment, and filtration products from Aprilaire, Abatement Technologies, and Guardsman. We don’t use hardware-store shop vacs or consumer-grade attachments. The same tools we bring to Bay Point homes are the ones commercial crews use in hospitals and schools. If your system has an Aprilaire media filter or a Guardsman UV unit installed, we service those components as part of the cleaning, and we stock replacement media for Bay Point customers so there’s no waiting on shipped parts.
Common Air Duct Cleaning Problems We See in Bay Point Homes
- Gray-black soot film in bayside flat ducts. The combination of Delta windblown dust, decades of rail and industrial activity near the waterfront, and moisture from winter tule fog creates a distinctive damp, musty contamination that cheap surface cleaning won’t touch.
- Clogged low-clearance mobile-home ducts. The manufactured homes along Port Chicago Highway and Bailey Road have undersized duct runs that load up faster than standard residential systems and require specialized equipment to access without damaging the flex or galvanized trunk.
- Dry construction dust in hillside subdivisions. The 1980s – 2000s homes above the flats show a completely different profile: fine drywall dust, pet dander, and pollen that responds to standard agitation and negative-air methods without the moisture complications of the bayside systems.
- Microbial growth from fogging “sanitizers” that never removed the source. We’ve opened too many Bay Point ducts where a previous vendor sprayed a scented fog that masked odor for two weeks, then the damp soot reactivated and smelled worse than before.
Pricing for Air Duct Cleaning in Bay Point, CA
A typical residential air duct cleaning in Bay Point runs $350 – $550 for a complete single-system job. HVAC duct cleaning with full system access, including the blower and coil, runs $450 – $650. Mobile-home systems on the flats typically fall in the $300 – $450 range due to smaller duct volume, though low-clearance access can add labor time. Commercial quotes follow a site visit; we don’t guess at square footage over the phone.
What moves the price: system size, contamination level, accessibility, and whether video inspection is requested. We give one flat price per system, agreed in writing before work starts. No per-vent pricing, no add-ons at the door, no bait-and-switch. Call (361) 326-5060 for an exact quote on your Bay Point home. Estimates are free.

FAQs About Air Duct Cleaning in Bay Point
Because surface spraying or register vacuuming doesn’t remove the gray-black soot-and-dust mix that’s bonded to the galvanized trunk lines. The damp from winter tule fog reactivates the odor. We put the system under negative pressure, mechanically agitate the trunk with rotary brushes, and pull everything through HEPA filtration. Call (361) 326-5060 for an exact quote – estimates are free.
Yes. Mobile homes have low-clearance, undersized ducts that clog faster and are harder to access without damaging the flex runs. We use smaller-diameter agitation tools and maintain tighter negative-air containment to prevent redistribution into the living space. Call (361) 326-5060 for an exact quote – estimates are free.
Most Bay Point homes benefit from cleaning every three to five years, but the wind-driven dust through the Diablo Gap and seasonal moisture from tule fog can accelerate buildup. Bayside flats homes with older galvanized ductwork often need attention sooner than hillside subdivisions with sealed rigid systems. Call (361) 326-5060 for an exact quote – estimates are free.
No. Fogging masks odor without removing the source. In Bay Point’s damp-soot conditions, that moisture can actually lock odors deeper into the debris and promote microbial growth. Mechanical removal with negative-air containment and HEPA filtration is what actually cleans the duct. Call (361) 326-5060 for an exact quote – estimates are free.
The full forced-air pathway: supply trunk and branch lines, return trunk and branch lines, registers and grilles, blower assembly, and accessible evaporator coil. We video-inspect before and after so you see what was removed. Call (361) 326-5060 for an exact quote – estimates are free.
