Why Novato Homes Are Different
Novato sits at the inland, northern end of Marin County, surrounded by dry grass hills that funnel wildfire smoke and seasonal grass pollen directly into homes during late summer and fall. This risk is far more acute here than in coastal Marin cities like Mill Valley or Tiburon. The daily thermal swing compounds the problem: afternoons run 10-15°F warmer than the coast, baking humidity from overnight marine air into duct liner materials. In the Ignacio area, we regularly find 1970s-era flex duct connections sealed with original cloth-backed duct tape that has fully delaminated, blowing conditioned air and accumulated debris into crawlspaces.
Air Duct Cleaning in Novato
Air duct cleaning in Novato requires more than a surface vacuum. Our valley position loads ducts with fine particulates from wildfire smoke that standard 1-inch filters miss, while aging 1960s-1970s housing stock means failed seals and disconnected flex duct are common. We use Rotobrush and Nikro equipment to agitate and extract debris from the full length of your runs, including hard turns and junctions where particulates settle. Every job starts and ends with camera inspection - you’ll see what we see. Air Duct Cleaning
Residential Duct Cleaning
Most Novato homes we clean are single-system ranch-style houses in the Ignacio area or along Novato Boulevard and Rowland Boulevard corridors. Many have never been properly cleaned. A typical residential cleaning runs $350-$550; larger homes or dual-zone systems range up to $650. After the 2020 fire season, we cleaned a system in the 94949 ZIP where the return trunk was coated with gray ash residue that had been recirculating for months.
Post-Fire-Season Cleaning
Supply ducts in Novato deliver more than conditioned air - they deliver whatever the system pulled from valley smoke events. We recommend HEPA-filtered agitation cleaning after significant fire seasons, typically $450-$650 for a full system including supply and return runs. Standard cleaning without HEPA extraction often leaves fine particulates in place. We’ll show you the camera footage and quote before we start.
How often should Novato homeowners clean their air ducts?
Most Novato homes benefit from professional duct cleaning every 3-5 years, but homes with original 1960s-1970s ductwork or heavy wildfire smoke exposure should consider every 2-3 years. The combination of valley-trapped particulates, thermal swing stress on materials, and aging housing stock means Novato systems accumulate debris faster than coastal Marin homes. Call (855) 401-6006 for a free assessment of your specific system and home age.
Dryer Vent Cleaning in Novato
Dryer vent cleaning in Novato typically runs $149-$189 for standard single-story homes, with two-story or extended runs at $189-$249. We’re familiar with the specific challenges of Novato’s 1960s and 1970s housing stock, from slab-on-grade ranches in Ignacio to redeveloped mid-century structures in Hamilton. Original flex duct softens with decades of heat cycling, and wildfire smoke particulates mix with lint to form dense blockages that standard filters don’t catch. Dryer Vent Cleaning
Vent Inspection and Cleaning
Every job starts with a camera inspection of your full vent run. In Novato’s older homes, we find collapsed flex duct inside wall cavities, heat-softened aluminum, and delaminated cloth-backed tape seals - especially in Ignacio-area slab-on-grade ranches. Our Rotobrush agitation system and Nikro vacuums remove compacted lint and ash residue that compressed-air blowers leave behind. We recently replaced a collapsed vent in a 1970s ranch on Rowland Boulevard where the homeowner had experienced months of intermittent dryer shutdowns.
Vent Rerouting
Many Novato homes have runs that are too long, too convoluted, or improperly pitched - problems baked into original construction and worsened by material fatigue. The overnight humidity from San Pablo Bay promotes mold growth in poorly pitched runs, which afternoon heat then bakes into place. Rerouting to achieve proper slope and code-compliant termination typically runs $249-$389. For Hamilton-area homes with retrofitted or mixed ductwork systems, this often solves chronic drying problems that cleaning alone cannot fix.
Why do older dryers in Novato’s ranch homes take so long to dry clothes?
It’s usually not the dryer; it’s the vent. In Novato’s 1960s and 1970s ranch homes, especially slab-on-grade properties in Ignacio and along Rowland Boulevard, original flex duct has often collapsed, separated at joints, or become packed with lint and wildfire ash that standard filters miss. The dryer overheats and cycles off before clothes are dry. We inspect with a camera, clear the blockage, and replace damaged duct with semi-rigid aluminum. Call (855) 401-6006 for an exact quote - estimates are free.
HVAC Cleaning in Novato
HVAC cleaning in Novato typically runs $280-$580 for a full system, with most jobs completed in a single visit. Our valley climate drives heavier cycling than coastal Marin, and wildfire smoke loading means your blower, coils, and cabinet collect debris that standard filters never touch. We clean each component individually, with before-and-after camera documentation. HVAC Cleaning
Evaporator Coil and Blower Cleaning
Novato’s summer heat pushes evaporator coils harder than in coastal cities. When coils clog with fire-season particulates or grass pollen, efficiency drops and ice buildup follows. Coil cleaning runs $180-$320. The blower motor and wheel collect everything your filter misses - wildfire ash, pollen, and dust that slips through aging duct tape seals in 1970s ranch homes. Blower assembly cleaning is $140-$240. We remove, clean, balance, and verify airflow with camera documentation.
Post-Fire-Season Deep Clean
After significant fire seasons, we see filters that appear clean while ducts are loaded with gray residue. Our post-fire-season deep clean with HEPA vacuuming runs $340-$620 for the full system, including coils, blower, and accessible trunk lines. We prioritize these appointments for Novato residents because valley-trapped particulates continue circulating long after visible smoke clears.
How soon after a wildfire should I have my HVAC cleaned in Novato?
Wait until outdoor air quality returns to normal, then schedule within 2-4 weeks. Fine particulates continue settling in ductwork after visible smoke clears, and running your system during that period distributes residue through the home. Our post-fire-season service includes HEPA vacuuming and camera verification. Call (855) 401-6006 - estimates are free, and we prioritize fire-season appointments for Novato residents.
Duct Repair & Sealing in Novato
Most duct sealing jobs in Novato run $280-$650 and are finished in a single visit. We’ve worked on homes from original 1960s Ignacio tracts to redeveloped Hamilton Air Force Base properties, and we know the failure patterns this valley’s climate creates. Cloth-backed duct tape delaminates, rigid sealants crack from thermal cycling, and corrosion accelerates where fire-season particulates meet overnight humidity. Duct Repair & Sealing
Mastic Sealant Application
Mastic is the only sealant we trust for Novato’s conditions. Unlike tape, it remains flexible through thousands of thermal cycles. We apply it to all joints, boots, and connections, then verify with a pressure test. In our valley microclimate, where afternoon heat bakes crawlspaces and overnight marine air drops them back to damp 60s, rigid sealants crack within seasons. Mastic moves with the metal. Single leak repair with mastic seal typically runs $180-$280.
Flex Duct Repair
The 1960s-70s ranch homes dominating Novato’s Ignacio area were built with flex duct connections sealed with cloth-backed duct tape that has a 15-20 year lifespan. Most is now 50+ years old. We strip failed tape, apply mastic to all joints, and re-wrap with foil tape as mechanical backup. Flex duct connection repair and reseal runs $220-$380. We back every repair with our 90-Day Done Right Promise - if it’s not right, we return at no charge with no paperwork.
Why do duct seals in older Novato ranch homes fail faster than in coastal Marin towns?
Novato’s inland valley produces hotter afternoons and cooler, more humid nights than coastal Mill Valley or Tiburon, creating a daily thermal swing that hardens and cracks sealants years faster. Coastal towns have moderate, stable temperatures; Novato’s ducts expand, contract, and stress their seals every 24 hours. We inspect with cameras and pressure-test to find every leak. Call (855) 401-6006 for a free inspection.
Air Quality & Sanitizing in Novato
Air quality and sanitizing service in Novato typically runs $280-$450 for whole-home duct sanitizing, with most appointments scheduled within 24-48 hours. If you’re noticing musty odors, lingering smoke smell after fire season, or allergy flare-ups, the problem usually starts in ductwork that hasn’t been properly cleaned or sealed. We treat mold, bacteria, and odor at the source - not with masking agents, but with removal and professional sanitizers. Air Quality & Sanitizing
Mold and Bacteria Treatment
Novato’s daily thermal swing - cool marine air overnight, afternoon heat 10-15°F above the coast - promotes mold growth in sheet-metal ducts, especially where original duct tape seals have failed. We treat mold with professional-grade sanitizers from Abatement Technologies, applied after HEPA vacuuming removes visible contamination. Accessible ductwork mold treatment runs $320-$580. For bacteria sanitizing, we use EPA-registered disinfectants with controlled foggers that reach full interior surfaces, including micro-pitting in 50-year-old sheet metal that standard cleaning misses.
Fire-Season Odor Removal
Smoke odor calls peak in late October and November, after Novato’s valley position has concentrated particulates from Marin and Sonoma county fires. Our process combines HEPA vacuuming, activated carbon treatment, and sanitizer application to kill odor-causing residues. For severe cases in homes with failed duct seals - especially Ignacio-area slab-on-grade ranches where flex duct has blown into crawlspaces - fire-season odor removal runs $350-$620. We’ll show you the camera footage and quote before any work begins.
Do I need air quality sanitizing every year after fire season?
Most Novato homes benefit from inspection annually after fire season, with full sanitizing every 2-3 years depending on fire severity and duct condition. Homes with intact, well-sealed modern ductwork may need less frequent service; homes with original 1970s flex connections or known liner degradation should be inspected yearly. Call (855) 401-6006 - we’ll recommend an interval based on your specific home and system age.

What Novato Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer finishes a load in one cycle now instead of two."
- Adam Pruitt"The allergies in this house had been bad since we moved in. It has been a couple of months since they did the ducts and it is noticeably better. Not a miracle, but real."
- Vikram Rao"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
