Why Novato ducts behave differently than the rest of Marin

Why does your Novato house get dusty when the AC runs, but your sister's place in Mill Valley doesn't? Geography. Novato sits in Northern Marin, the county's warmest and driest town. The inland valley is shielded from direct coastal fog. Summer afternoons hit 90F+. That gives this town the longest cooling season in our service area, so the system runs more hours and pulls more air through the ducts.

Housing here skews later than the rest of Marin. Large 1960s-80s subdivisions. Then 1990s-2000s building at the former Hamilton Field airfield. Mostly slab-on-grade or crawl, with insulated flex duct run through vented attics. That is the weak point. A vented attic over 130F in August cooks the flex. The inner liner sweats where cold air meets hot sheet metal. Runs sag between supports. Takeoffs at the plenum work loose over years.

What gets drawn in is local too: grass and oak pollen, dry-season dust off surrounding grassland and open space. The valley edges are wildland-urban interface, so smoke season particulate load is high here.

Check this yourself. Open the attic hatch and look for flex lying on the joists in a long belly. Feel a register in the farthest bedroom with the fan on high.

Frequently Asked Questions

My vents never seem to put out much air in the back bedrooms once it gets hot. Is that a duct cleaning problem?

Sometimes, but in Novato it's just as often a duct problem. Most homes here from the 1960s-80s subdivisions and the Hamilton-era building run insulated flex through a vented attic, and those attics push well past 130F on a summer afternoon. Flex sags between supports, kinks at bends, and works loose at the takeoff collars over the years. When we inspect, we tell you which it is. If a run has pulled off the plenum or collapsed on itself, cleaning it won't fix the airflow, and we'd rather say so than clean a line that needs to be re-hung or re-sealed first.

How soon can someone actually get out here?

Novato is usually a next-day or within-a-few-days visit for us in a normal week. The crunch is the back half of summer and smoke season, when calls spike across northern Marin at the same time. If your AC is running long hours and the air smells like attic or smoke, call earlier rather than waiting for a cooler week, because the cooler week is when everybody else calls too.

Do you ever do same-day?

Often, yes, especially mornings. Duct cleaning is a half-day-ish job for a typical single-story Novato home, so one cancellation opens a slot. Same-day depends on where the truck already is that morning and how many returns and supply runs your system has. A larger 1990s-2000s two-story with multiple returns is harder to squeeze in than a smaller single-return ranch. Call and ask rather than assuming; we'll tell you straight whether today is realistic.

We're on the open-space edge of the valley. Does that change what's in our ducts?

It does. Homes backing grassland and oak get a heavier load than ones in the middle of town: dry-season dust, grass and oak pollen pulled in during long AC cycles, and fine particulate during smoke season. That mix settles in the supply runs and packs the return side and filter area. We pay extra attention to the return, since that's where the bulk of it collects, and we'll be honest about your filter. If the filter housing leaks around the edges, cleaning the ducts buys you less time than fixing the leak would.

What makes one Novato house cost more than the next?

Mostly the count and the condition. Price tracks how many supply runs and returns the system has, so a larger Hamilton-area home with two zones runs higher than a compact single-story. Beyond that, attic access matters. Crawling a low, hot vented attic to reach takeoffs takes longer than a house with a generous attic hatch. And if we find flex that's torn, sagging, or disconnected at a collar, that's repair work that's separate from cleaning. We'll show you what we found and let you decide before anything beyond the cleaning happens.
