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 Saranap
Air duct cleaning in Saranap typically runs $350 – $650 for a whole-home system and is scheduled within a few business days. We’re familiar with the fog-belt ranches along Tice Valley Boulevard and the low-pitch attics near Saranap’s border with Lafayette, so we know what to look for before we arrive.
Hollis Air Duct Cleaning dispatches crews to Saranap from our San Francisco Bay Area coordination office. We’ve worked the mid-century housing stock here long enough to recognize the pattern: original flex-duct laid over insulation, cool damp attics that never fully dry, and the musty odor that follows. If your vents are pushing dust or your system sounds like it’s working harder than it should, call us at (361) 326-5060. We’ll give you a written price before any work starts and back it with our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Saranap’s Preferred Air Duct Cleaning Company
Saranap homeowners know the difference between a crew that understands local conditions and one that’s guessing. We’ve cleaned ducts in the ranch homes off Pleasant Hill Road and the properties tucked behind the Saranap Swim Club. That local knowledge means we don’t waste time figuring out your attic layout or why your system smells musty in July when the fog rolls in.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. That’s The Garrison Standard, and it applies to every job we run in Contra Costa County. We price in writing before touching equipment, and if anything fails within a year, we come back at no charge. 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 appointment and confirm your written estimate, not a callback queue that dumps you into voicemail.
Air Duct Cleaning Services in Saranap
Air Duct Cleaning Services in Saranap cover the full removal of dust, debris, and microbial buildup from your supply and return ductwork. A typical residential job here runs $350 – $550 for a single-system home, with larger or more complex layouts reaching $650. Most Saranap homeowners schedule this every 3 – 5 years, though the damp attic conditions in this fog belt can accelerate buildup and odors.
Residential System Cleaning
We use a Rotobrush rotary brush system paired with negative-air collection to agitate and extract debris without blowing it into your living space. For Saranap’s older ranch homes, this means working carefully around original flex-duct that may be brittle or sagging. Our Air Duct Cleaning team inspects each run before agitation to avoid damage.

Video Inspection Before and After
Our Nikro video inspection system lets you see inside your ducts before we start and after we finish. In Saranap, this matters because condensation-related mildew often hides in low spots that homeowners can’t smell from every room. The before-and-after footage is yours to keep.

HVAC Duct Cleaning in Saranap
HVAC Duct Cleaning in Saranap addresses the entire forced-air system, including the air handler, coils, and registers, not just the visible vent covers. Because Saranap’s cool, humid attic environment keeps duct surfaces damp year-round, microbial growth and musty odors are more common here than in hotter inland East Bay cities. A full HVAC duct cleaning in Saranap typically costs $450 – $650 and includes sanitization of the air handler cabinet.
Air Handler and Coil Cleaning
The indoor coil and blower assembly collect the same moisture and debris that lines your ducts. We clean these components as part of a full HVAC duct cleaning to prevent recontamination the moment the system cycles back on. This is especially important in Saranap, where high humidity means coils stay wet longer and biofilm develops faster.
Register and Grille Detailing
We remove and hand-clean every supply and return grille, not just vacuum around them. Kitchen registers in Saranap’s older homes often show a sticky residue from decades of cooking grease that standard vacuum attachments won’t touch.
Trusted Brands We Service in Saranap
We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman for fast turnaround on Saranap jobs. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use in hospitals and schools. When your system needs a filter upgrade or a damaged section of flex-duct replaced, we don’t order parts and make you wait. We carry what Saranap’s common systems require and install it during the same visit when possible. If you’re also dealing with a clogged dryer vent, we handle Dryer Vent Cleaning in Saranap with the same equipment and the same written pricing standard.
Common Air Duct Cleaning Problems We See in Saranap Homes
- Standing condensation in low duct runs. Technicians working Saranap’s older ranch attics regularly find sagging flex-duct between joists with pooled water in the belly. This fog-belt pattern is rare in hotter inland East Bay cities and creates a breeding ground for mildew that circulates through every room.
- Brittle original flex-duct from the 1960s-70s. Many Saranap homes still run first-generation flexible ductwork that cracks under gentle pressure. We inspect before agitating and will show you damage on camera before recommending repair or replacement.
- Insulation debris inside ducts. When original flex-duct sags onto attic insulation, vibration and airflow slowly pull fiberglass particles into the airstream. Homeowners notice this as a fine dust that resettles quickly after surface cleaning.
- Musty odor that returns within weeks of basic filter changes. In Saranap’s damp climate, changing the filter addresses symptoms, not the source. The microbial growth lives on duct walls and in the air handler, which is why full system cleaning is necessary for lasting results.
Pricing for Air Duct Cleaning in Saranap, CA
Whole-home air duct cleaning in Saranap runs $350 – $550 for most single-system ranches, with larger homes or systems with extensive contamination reaching $650. HVAC duct cleaning that includes the air handler and coil typically falls between $450 – $650. We also offer Duct Sealing in Saranap for homes where leaks are driving energy costs up, priced separately based on linear footage of accessible ductwork.
What moves the price: the number of HVAC zones, accessibility of attic or crawl-space runs, whether video inspection is included, and the condition of the existing ductwork. We do not quote per-vent pricing, and we do not bait you with a low teaser that jumps once the van is in your driveway. The price is written down before any work starts. That’s The Garrison Standard, and it’s how we’ve operated since 2004.
Call (361) 326-5060 for a free estimate. We’ll ask about your home’s size, system age, and any symptoms you’ve noticed, then give you a firm range with no obligation.

Yes, we work the full Saranap area, including properties along Tice Valley Boulevard, the ranch tracts near the Lafayette border, and the homes tucked behind the Saranap Swim Club. Our technicians are familiar with the local housing stock and attic configurations specific to each section.
We do not offer same-day emergency dispatch for duct cleaning, as it is a scheduled maintenance service rather than an urgent repair.

Saranap pricing is consistent with our Contra Costa County rates and comparable to Lafayette and Walnut Creek. The unique factor here is the fog-belt humidity, which can mean more extensive microbial remediation in attics that stay damp year-round. We assess this during your free estimate and price accordingly, with no surprises at the door.
If any part of our cleaning fails within one year, we return and make it right at no charge, including a free second visit. This covers recontamination due to incomplete extraction, equipment failure, or any issue traceable to our work. The promise is backed in writing on every job, not a verbal assurance that disappears after checkout. Call (361) 326-5060 with any concern, and we’ll schedule the follow-up.
