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 Novato
Air duct cleaning in Novato typically runs $350 – $650 for a full residential system and is usually completed in one visit. We serve Novato from our San Francisco Bay Area dispatch office, with crews that know the rural roads around Pleasant Valley, the oak-woodland edges near Stafford Lake, and the tighter lots in Hamilton. Call (361) 326-5060 for a free estimate with a written price before any work starts.
We’ve been cleaning ducts in Novato long enough to know the local pattern: homes with forced-air furnaces paired with whole-house fans, original galvanized steel ductwork from the 1950s through 1980s, and dust loads that suburban contractors from denser Bay Area cities rarely encounter. Our Air Duct Cleaning team arrives with rotary brush systems, negative-air machines, and the patience to treat your ductwork as two separate contamination zones, not one.
Why Hollis Air Duct Cleaning Is Novato’s Preferred Air Duct Cleaning Company
Novato homeowners don’t need another coupon in the mailbox promising a $49 whole-house special that balloons to $800 at the door. Hollis Air Duct Cleaning, part of the Garrison Partners family since 2004, prices every job in writing before a tool touches your system. That discipline matters more here than in most markets, because Novato’s dual-system homes take longer to assess properly and shortcut artists rarely account for the whole-house fan side.
Our technicians are background-checked, uniformed, and expected to follow The Garrison Code on every Novato job: arrive inside the quoted window, explain what we found, price it in writing, complete the work by the book, and leave the site clean. If something fails within a year, our 365-Day Done Right Promise covers a free return visit to make it right. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, seven days a week. Scheduling for Novato is coordinated from our San Francisco Bay Area office, and we build realistic drive times into every appointment window, especially for properties off the paved grid near the rural western edge.
HVAC Duct Cleaning in Novato
HVAC Duct Cleaning in Novato means addressing both the furnace-driven supply and return network and the separate intake path created by whole-house fan systems common in this market. The job involves source removal: we place the duct system under controlled negative pressure using a Nikro negative-air machine, then agitate debris with a Rotobrush rotary brush system so particles suspend and extract rather than resettle. A typical residential HVAC duct cleaning in Novato runs $350 – $550 for a single-system home, $450 – $650 when we must treat the furnace trunk and the whole-house fan plenum as distinct zones.
Most Novato homeowners need this service when they notice uneven heating, visible dust puffing from registers, or a persistent musty odor after the first heavy rains. The 1950 – 1980 housing stock in Hamilton and Pleasant Valley often has galvanized steel ductwork with decades of accumulation and joints that have loosened with thermal cycling.
Supply and Return Separation
We clean supply ducts and return ducts as separate pressure zones. In Novato’s mid-century ranches, return lines often run through unconditioned crawl spaces where seasonal moisture degrades insulation, while supply branches push conditioned air to living spaces. Separating the two lets us inspect each for distinct problems: pollen loading in returns, joint separation in supplies, moisture staining in either.
Post-Cleaning Verification
After agitation and extraction, we run a video inspection to confirm debris removal and identify any structural issues we could not see through the dust layer. This step is non-negotiable on older galvanized systems where rust-through or joint failure may be hidden behind register boots.
Vent Cleaning in Novato
Vent Cleaning in Novato targets the terminal points where your ductwork meets the room: wall and floor registers, ceiling diffusers, and the boot connections behind them. This is not a surface wipe. We remove each register, clean the boot and first few feet of branch line, and treat the grille itself to remove the fine oak-pollen film that settles on Novato homes during dry summer months. Standalone vent cleaning runs $150 – $275; most customers bundle it with full system cleaning.
Vent cleaning matters most when you see dark buildup on grille louvers, smell stale air when the system kicks on, or notice one room consistently warmer or cooler than others. In Novato’s ranch-style homes with original duct layouts, vent boots are often the first place we find evidence of whole-house fan debris migration, the fan having pulled outdoor particles deep into the branch lines.
Register Removal and Deep Boot Cleaning
We pull every register, vacuum the boot cavity with HEPA filtration, and hand-clean grilles to remove the oily pollen film that standard dusting misses. This matters in Novato because oak pollen combines with road dust from unpaved rural lanes to form a tenacious layer.
Grille Restoration or Replacement
Bent or rusted grilles get noted and options explained. We stock common sizes and finishes for faster turnaround on standard Novato home configurations.
Trusted Brands We Service in Novato
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct walls, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t show up with shop vacs and compressed air. The tools we run are the same ones commercial crews use in hospitals and schools, and we explain what each does while we’re setting up. For Novato customers, this means we can source Guardsman filtration upgrades and Honeywell media replacements without the multi-week delays that come from ordering through national distribution chains unfamiliar with local inventory.
Common Air Duct Cleaning Problems We See in Novato Homes
- Dual-system contamination from whole-house fans. Because so many Novato homes run a forced-air furnace alongside a whole-house fan, ducts here collect two separate contamination streams – furnace side and fan side – that must be cleaned as distinct source-removal zones in one visit; a single-pass cleaning misses half of what the fan pulls in off the oak woodlands and wetlands.
- Decades of debris in original galvanized ductwork. Much of Novato’s housing stock consists of single-family homes built between 1950 and 1980, with many mid-century ranch-style houses in neighborhoods like Hamilton and Pleasant Valley; these homes typically have original galvanized steel ductwork that can accumulate decades of debris and may have loose joints that leak air.
- Seasonal moisture and mold in crawl space runs. Novato’s Mediterranean climate features warm, dry summers and mild, wet winters, with frequent morning fog and proximity to the Pacific; the seasonal moisture can lead to mold growth in ductwork, while dry summer conditions increase dust and pollen infiltration, especially from the surrounding oak woodlands.
- Post-rain musty odors from saturated insulation. After the first heavy rains in late fall, technicians often find that ducts in older Novato homes emit a musty odor because water seeps into crawl spaces and saturates the duct insulation, a problem less common in drier inland areas.
In the Pleasant Valley neighborhood, we opened a mid-century ranch’s original galvanized supply and return ducts and found the branch runs packed with oak pollen and fine road grit, while the whole-house fan’s intake plenum held its own layer of dry-season debris. After camera inspection we set up negative pressure with HEPA filtration, ran agitation tools through both the furnace trunk and the fan run, and cleaned the blower motor and air handler separately – cleaning one system without the other would have just re-contaminated the ducts within the first hot week.
Pricing for Air Duct Cleaning in Novato, CA
Most full-system residential cleanings in Novato fall between $350 and $650, depending on system count, duct material, and accessibility. A single forced-air furnace with standard galvanized trunk and branch lines typically lands at $350 – $450. Add a whole-house fan with its own intake plenum and duct tie-ins, and the range moves to $450 – $650 because we’re treating two distinct contamination sources as separate zones. Standalone vent cleaning runs $150 – $275. Commercial systems and outbuilding ductwork get priced by inspection.
What moves the number: duct length and layout, number of registers, presence of mold or moisture damage requiring remediation referral, and whether we can access the system through standard registers or need to cut access panels in the trunk. We do not quote per-vent pricing. We do not bait with a low opener and revise at the door. The price is written down before work starts, and it does not move. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Novato
Every 2 – 3 years for rural Novato properties, not the generic 3 – 5 year interval you see nationwide. Unpaved roads, whole-house fans pulling from oak woodlands, and longer heating seasons with wood or pellet stoves load ducts faster than suburban equivalents. Call (361) 326-5060 and we’ll assess your specific contamination sources.
Yes. The fan creates a separate intake path that pulls outdoor dust, pollen, and road grit directly into your duct network. We clean the furnace side and the fan side as distinct zones with separate agitation and extraction cycles. Skipping the fan plenum means re-contamination within days. Call (361) 326-5060 for a system assessment.
Water seeps into crawl spaces and saturates duct insulation on older galvanized systems, especially in Novato’s 1950 – 1980 housing stock. Cleaning the duct interior without checking insulation condition leaves the odor source intact. We inspect and note saturated insulation during every visit. Call (361) 326-5060 if you smell musty air when the heat kicks on.
Yes. We clean ductwork in detached shops, barns converted to studios, and guest cottages with independent systems. These often run on mini-splits or wall furnaces with short duct runs that accumulate debris differently than main-house systems. Pricing starts around $200 – $350 for simple layouts; complex systems get priced after inspection. Call (361) 326-5060 to schedule.
We arrive in the quoted window, inspect your system with a camera, explain what we found, and give you a written price before starting. If you approve, we set up negative-air containment, run rotary brushes through each zone, clean registers and boots, verify with post-cleaning video, and leave the site clean. The whole process typically takes 3 – 5 hours for a standard Novato home. Call (361) 326-5060 to book.
