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.

We know this valley. The canyon roads off Homestead Boulevard, the older wood-sided homes climbing up from Edgewood Avenue, the tight crawlspaces in Homestead Valley where flex runs disconnect and nobody notices for years. Our crews work this terrain every week. Before-and-after photos of your own ducts come standard. So does a written price before we start.
Air Duct Inspection in Tamalpais-Homestead Valley
Air Duct Inspection in Tamalpais-Homestead Valley means we run a camera through your return and supply runs before quoting anything. You see what we see. That matters here because so many homes in Homestead Valley were built on slopes with duct chases that shift over time, and a disconnected flex run in a crawlspace can silently pull in eucalyptus debris, fine redwood needles, and canyon dust for years. A camera shows exactly what’s happening inside the duct, not a guess from the register.
What the Camera Shows
We run a high-resolution probe through the return side first, then the supply trunks. The footage reveals collapsed sections, disconnected joints, gaps where insulation has pulled away, and visible accumulation on the blower motor vanes. For homes along Evergreen Avenue or Montford Avenue where duct chases run tight against hillside moisture, we also look for condensation staining that points to inadequate sealing.
When an Inspection Makes Sense
Most people book a duct inspection in Tamalpais-Homestead Valley when they notice one room staying stubbornly hot in summer, hear rattling at a register, or see visible dust bloom when the furnace kicks on at the start of heating season in late October. It’s also worth doing before buying an older home in the valley, since a full duct replacement in a tight canyon crawlspace can run several thousand dollars. An inspection typically costs $95 – $165 when booked alone, and we credit that amount toward the cleaning if you schedule both.
Residential Air Duct Cleaning in Tamalpais-Homestead Valley
Residential Air Duct Cleaning in Tamalpais-Homestead Valley means source removal, not a quick vacuum at the registers. Homes here sit under redwood, oak, and eucalyptus canopy. That’s beautiful, but it means fine needles, acacia pollen, and dry leaf fragments find their way into return ducts, the air handler cabinet, and the blower motor itself. We loosen it mechanically inside the duct and extract it with HEPA-filtered negative pressure. Standard homes in this market run $380 – $720, full system.
The Rotobrush System
We run a Rotobrush rotary brush through each supply and return run, then a Nikro HEPA vacuum under negative pressure to pull loosened debris out of the system and into a sealed containment unit. Negative pressure just means the vacuum is stronger than the brush’s push, so the stuff we’re removing goes into the filter, not back into your living room. Combined with an Abatement Technologies containment unit, the job stays clean from start to finish.
The Air Handler and Blower
Most homeowners never see their air handler. It sits in an attic knee wall or a crawlspace corner where redwood needles and dust collect on the blower vanes and reduce airflow. We open the cabinet, remove the panel, and clean the blower motor, evaporator coil face, and drain pan. This part of the job matters most in Tamalpais-Homestead Valley because the canyon microclimate pushes two-to-three times more fine particulate matter through the return than a flat, inland homesite. If you skip the air handler, you’ve cleaned half the system.
Trusted Brands We Service in Tamalpais-Homestead Valley
We service and maintain systems built around Honeywell filtration, Aprilaire media cabinets, and existing Abatement Technologies containment setups. For Homestead Boulevard ranch homes with Aprilaire 2400 series air cleaners, we stock replacement media on the truck. That means no second trip to a parts counter in Corte Madera. When we open a Honeywell media cabinet on a 1970s split-level and find the filter collapsed into the blower section, we can replace it on the spot and continue the cleaning. If your system runs a Guardsman or Nikro filtration setup, call (737) 727-2314 and tell us the model; our techs will confirm parts availability before arriving.
Common Air Duct Cleaning Problems We See in Tamalpais-Homestead Valley Homes
- Redwood needles and eucalyptus debris packed in return ducts. Homes tucked under the tree line along Edgewood Avenue pull leaf litter and pine debris straight into the return side where it piles against the filter rack. Over time this reduces airflow enough to shorten furnace life.
- Disconnected flex runs in hillside crawlspaces. Tamalpais-Homestead Valley homes often have crawlspaces cut into slope, and the flex duct joints there loosen on their own. A disconnected run pulls unconditioned crawlspace air, dust, and moisture directly into the supply path and blows it into bedrooms.
- Collapsed duct liner in older metal trunk lines. Duct chases running through older attics and knee walls sometimes fail along the liner. The liner sags, catches debris, and restricts airflow to the far end of the house, which is why one end of a Homestead Valley house can feel ten degrees warmer than the other.
- Blower motors caked with fine canyon dust. The same microclimate that dries out redwood foliage in summer suspends fine dust in the air. That dust settles on blower vanes, imbalances the wheel, and causes bearing noise. A clogged blower has to work harder to move less air, and power bills climb with it.

FAQs About Air Duct Cleaning in Tamalpais-Homestead Valley
Every three to five years for most homes, though canyon-side properties under heavy redwood and eucalyptus canopy often need attention every two to three years. The tree debris in this part of Marin loads up return ducts faster than inland neighborhoods. If you just moved in and don’t know the last cleaning date, book a camera inspection first and make the call from there. Call (737) 727-2314 and we’ll help you figure out the timeline for your specific home.
One flat price for the whole system, always. We quote the job, you approve the number, and that’s the price. We don’t price per vent because that pushes homeowners to skip the air handler and blower motor, which is exactly where the debris in Tamalpais-Homestead Valley builds up. The written price covers the entire job before anything starts.
Source removal means we physically loosen and extract the material inside your ducts rather than running a shop vac over the register grilles. Negative pressure is the method: the Nikro HEPA vacuum pulls harder than the brush pushes, so everything we remove goes into a sealed Abatement Technologies containment unit instead of recirculating into the room. You’ll see before-and-after photos of the inside of your ducts, not a generic stock image.
No. Duct cleaning is a scheduled job, and a proper source-removal cleaning takes three to five hours. Anyone promising same-day work is likely doing a quick once-over at the registers and calling it done. We book Tamalpais-Homestead Valley jobs on a real schedule, give you a live trackable arrival window through The Relay Standard, and the tech shows up at the time you picked. Call (737) 727-2314 to find the next available slot.
Duct cleaning alone won’t solve indoor air quality, and we tell every Tamalpais-Homestead Valley homeowner the same thing. What it does is remove the accumulated material that your HVAC system pushes through the house every cycle: dust, pollen, pet dander, and that fine redwood needle debris our valley is known for. If you’re also running a good MERV-13 filter or an Aprilaire media cabinet, clean ducts mean that filter actually does its job. Call (737) 727-2314 if you want an honest take on whether your system is part of the problem.
Tamalpais-Homestead Valley Duct Cleaning, Done Right
We recently cleaned a 1970s split-level on Edgewood Avenue where the homeowner kept finding fine redwood needles on their supply registers after every windy week. Using a Rotobrush with HEPA filtration under negative pressure, our techs pulled the return-side debris from the air handler and agitated the main trunk lines, then showed the owner before-and-after photos of the ducts and a clear lint pathway on the blower motor. No per-vent pricing. One flat price for the system, agreed up front. That’s the standard we hold for every Tamalpais-Homestead Valley job, because the housing here, the tree cover, and the canyon dust all demand the same thing: the actual cleaning, not a register-level touch-up.
Our crews know Miller Avenue, the winding streets off Montford and Evergreen, the tight crawlspaces that make Homestead Valley unique. They carry Rotobrush, Nikro, and Abatement Technologies equipment. They arrive background-checked and in uniform, and you’ll know the technician’s name before they knock. Every job includes a live trackable arrival window, a written price before work begins, before-and-after photos of your own ducts, and a 365-Day Done Right Promise. If the work isn’t right within a year, we come back and make it right at no charge.
