Fast, Reliable Air Duct Cleaning Across Sonoma

Air duct cleaning in Sonoma typically runs $450-$850 for a whole-home residential system, with most jobs completed in a single morning or afternoon. We serve Sonoma from our San Francisco Bay Area dispatch office, with crews that know the valley’s specific challenges: wildfire smoke residue from events like the 2017 Nuns Fire, elemental sulfur drift off surrounding vineyards, and the quirks of older homes with retrofitted ductwork.

Call (323) 918-4345

We’ve been working in Sonoma since 2005, and our technicians know the difference between a standard suburban duct system and what we find near the historic Plaza - 1920s bungalows with 1980s add-on ducts, mid-century ranches with original galvanized runs, and newer wine-country estates with complex zoned systems. Every visit starts with a written price before any work begins, shoe covers and drop cloths from the moment we walk in, and a photo of the clean-up before we leave.

Why Morton’s Air Duct Cleaning Is Sonoma’s Preferred Air Duct Cleaning Company

Sonoma homeowners call us back because we treat the house like it’s our own. Paul Adeyemi built Morton’s on the Cedarwell Care Promise, which means background-checked, uniformed technicians who work quietly during nap hours, use pet-safe products where available, and never leave a mess behind.

Our local reputation comes from fixing problems other cleaners miss. In the Sonoma Valley, that means knowing how to spot disconnected retrofitted duct runs behind kitchen walls and understanding why standard agitation doesn’t remove the chalky yellow sulfur residue that collects on supply registers every harvest season. We’re not learning Sonoma’s housing stock on your dime - we’ve been crawling through attics off Broadway and East Napa Street since 2005.

A live person answers our phone 24/7. Not a voicemail, not a chatbot. When you schedule Air Duct Cleaning with us, you’ll get a specific arrival window, a text when the crew is en route, and that written price in your hand before anyone touches your system.

Every job carries our 365-Day Done Right Promise. If something isn’t right, we make it right. Full stop.

Air Duct Inspection in Sonoma

Air Duct Inspection in Sonoma is where we always start, because too many homes here have duct systems that were cleaned but never properly diagnosed. Our inspection runs $150-$250 and includes a full video scan of your trunk lines and branch runs, airflow testing at each register, and a written report with photos of what we found.

Sonoma’s bowl-shaped valley, framed by the Mayacamas and Sonoma Mountains, traps both wildfire smoke from events like the 2017 Nuns Fire and fine elemental sulfur dust drifting off surrounding vineyards, concentrating both in residential HVAC intakes at ground level. That combination of agricultural drift and documented smoke infiltration doesn’t occur in neighboring cities. An inspection shows whether your ducts are simply dirty, or whether they’re actively pulling contaminated attic or crawlspace air through gaps and disconnects.

Video Camera Scanning

We feed a self-leveling camera through your supply and return lines, recording every joint, seam, and transition. In Sonoma’s older homes, we regularly find crushed flexible duct behind walls, original galvanized runs rusted through at the seams, and 1980s retrofits where the installer never properly sealed the connection to the air handler. You watch the footage with us. No guesswork.

Airflow and Leak Detection

We measure static pressure and airflow at each register to identify blockages and leaks. A disconnected return duct in a crawlspace can pull musty, contaminated air straight into your living space, and the homeowner only knows something’s wrong because the house smells odd or the energy bill climbed. The numbers tell the story.

Residential Air Duct Cleaning in Sonoma

Residential Air Duct Cleaning in Sonoma addresses the specific contamination profile of valley homes: layered wildfire ash, vineyard sulfur dust, and decades of normal household accumulation in duct systems that were often retrofitted into structures never designed for forced air. A typical whole-home cleaning runs $450-$850 depending on system size, accessibility, and whether we find disconnected runs that need sealing.

We pulled up to a 1920s bungalow a few blocks off the Plaza, where the homeowners had noticed a chalky yellow residue collecting on their supply registers every harvest season. A camera inspection showed the return and supply ducts were an add-on system from the 1980s with a disconnected run behind the kitchen wall, pulling attic air straight into the air handler; we set up negative pressure with HEPA filtration, ran agitation tools through the branch runs, reconnected and sealed the break, and the residue stopped returning. Our tech also swapped their filter to a higher MERV rating to catch the fine particulate that used to blow through.

Negative Pressure HEPA Containment

We don’t stir up Sonoma’s specific contaminants and hope for the best. Our Nikro and Abatement Technologies equipment creates true negative pressure at the duct system, pulling debris through HEPA filtration before it enters your home’s air. This matters enormously here. Wildfire ash and elemental sulfur are fine particulates that a shop vac or low-powered machine will simply redistribute through your living space.

Register, Grille, and Air Handler Cleaning

The job isn’t done when the ducts are clear. We remove and hand-clean every supply and return grille, clean the air handler cabinet and blower assembly, and replace your filter with one rated for your system’s airflow and Sonoma’s particulate load. We leave the mechanical room cleaner than we found it, with a photo for your records.

Trusted Brands We Service in Sonoma

Our crews carry professional-grade equipment from Rotobrush, Nikro, Aprilaire, and Abatement Technologies, not rental-shop gear that loses suction halfway through a job. For Sonoma’s older homes with original or retrofitted ductwork, we stock a range of flexible duct diameters, mastic sealant, and mechanical fasteners so we can repair disconnects and gaps on the spot rather than scheduling a return visit. That means faster turnaround for you and a system that actually performs better after we leave, not just cleaner. We also source Aprilaire media filters and Guardsman protectants locally when your system needs upgraded filtration against valley particulates.

Common Air Duct Cleaning Problems We See in Sonoma Homes

• Disconnected retrofitted runs in pre-WWII homes. The charming bungalows near Sonoma Plaza often have duct systems added in the 1970s-1990s by cutting through walls and floors without proper support. We find sagging flexible duct that has pulled free at the collar, blowing conditioned air into wall cavities and pulling unfiltered attic air into the return. Cleaning the ducts without reconnecting and sealing these breaks leaves the root problem untouched.
• Chalky elemental sulfur residue in supply ducts. During late summer and fall harvest, vineyard equipment kicks up fine yellow sulfur powder used as organic fungicide, and Sonoma’s valley topography concentrates it at ground level. Standard rotary brushing can miss this residue entirely. We use targeted agitation and HEPA extraction, and we know to look for it because we see it every season.
• Wildfire ash settled in low-velocity trunk lines. The 2017 Nuns Fire pushed toxic particulate deep into thousands of Sonoma homes’ ductwork. Ash is heavier than household dust and settles in horizontal trunk lines, especially in systems that weren’t run continuously during the smoke event. Low-powered equipment stirs it up without removing it. Our negative pressure systems capture it completely.
• Original galvanized duct rusted through at seams. Mid-century ranch homes in the Sonoma Valley often have original metal ductwork that has corroded where condensation collects. We spot these failures during camera inspection and can replace sections with modern insulated flex or hard pipe, sealed properly against future leakage.
