Air Duct Cleaning in San Martin, CA

Frequently Asked Questions

We're surrounded by vineyards and orchards, and the house is on a gravel drive. How fast does that dust actually build up in the ducts?

Faster than it would in a tract neighborhood with paved streets and lawns. Between tractor-raised soil in the orchards, dry-grass particulate in late summer, and fine grit kicked up off unpaved drives and gravel shoulders, the load coming into a San Martin return is heavier and finer than normal household dust. Fine grit passes through a standard filter more easily than lint does, so it ends up in the supply runs and on the blower wheel. Most homes out here benefit from being checked on a shorter interval than a suburban house, and we'd rather tell you the ducts look fine than clean them on a schedule that doesn't match what we find.

Our place is a manufactured home with the duct running underneath. Can you clean that, or is it different work?

We clean it, but it is different work and we'll say so up front. Underfloor and belly duct in manufactured homes is often flex or sheet metal in a sealed belly wrap, with the registers in the floor rather than the ceiling. Access is through the floor boots, and the condition of the belly wrap matters as much as the cleaning does. If the wrap is torn or the duct has separated from a boot, cleaning alone won't hold, because the run will just pull crawlspace air and soil back in. We inspect before committing to a method, and if what you need is a repair rather than a cleaning, that's what we'll tell you.

We found droppings near a floor register. Does that change the job?

Yes, and it's one of the more common things we deal with in San Martin. Underfloor duct in crawlspaces and belly ducts is a sheltered, warm run, and rodents get into it through gaps around pipe penetrations, torn belly wrap, or an open crawlspace vent. Once they're nesting in a duct, you're circulating nesting material and waste every time the system runs. That job involves removing the contamination, sanitizing the affected runs, and identifying the entry point. Cleaning without sealing the entry just resets the clock. We also check the outbuilding side of things if a duct run or unit is near one, since that's often where the activity starts.

What makes one San Martin house cost more than another?

Mostly the duct layout and what we find inside it. Larger parcels out here often come with larger homes and longer runs, sometimes with a second system or a unit serving a converted outbuilding, and more runs means more work. Underfloor duct in a crawlspace takes longer to access than attic duct you can stand up next to. Rodent contamination or a torn belly wrap adds to the job because it isn't just cleaning anymore. A straightforward ranch home with accessible duct and ordinary agricultural dust sits at the lower end of what we do. We walk the system and tell you what we're looking at before anything gets started.
