Question 1

I live in campus faculty housing — do I need approval before scheduling duct cleaning?

Accepted Answer

Often, yes. Most homes on Stanford land are university-owned rather than individually owned, so the decision usually runs through the housing office or your property manager, not just you. If you're a tenant or ground-lease resident, check who's responsible for the HVAC system before booking. We're used to coordinating with housing staff, and we can send a scope description they can approve. If you own your structure outright on leased land, you can schedule directly.

Question 2

Why does my house get dusty again so quickly after a cleaning?

Accepted Answer

The canopy here works against you. Mature oaks, eucalyptus and redwoods drop fine debris and pollen through spring, and the open dry grass hills add seed and chaff through the summer. That material gets pulled in through return grilles and door gaps, then redistributed every time the fan runs. Duct cleaning removes what's settled inside the system, but it won't stop new loading. Tighter filtration and a sensible filter change interval do more for week-to-week dust than cleaning frequency alone.

Question 3

What usually goes wrong in the older homes here?

Accepted Answer

In the 1920s-50s structures with crawlspace or basement duct runs, the recurring issues are disconnected or sagging joints, insulation that's broken down and shedding, and crawlspace soil dust pulled into leaky return paths. Those runs were often added or rerouted over decades, so you find segments nobody has looked at in a long time. On the newer campus-adjacent builds with flex in attics, the failures are different: kinked or crushed flex, runs resting on joists at a sag, and connections at the boot that have loosened over time. We inspect before cleaning so you know which category you're in.

Question 4

Can you come out the same day?

Accepted Answer

Sometimes, though it depends on the day and where the job sits. Jobs on university land that need access coordination or a housing-office sign-off rarely happen same day, because the approval takes longer than the drive. If you own your home and can grant access yourself, same-day is more realistic when we have an opening. For a genuine problem, a smell from the vents, visible debris blowing out, tell us when you call and we'll work to move you up rather than default you to the next open slot.

Question 5

What makes one Stanford house cost more than another?

Accepted Answer

Mostly access and system layout. An older home with crawlspace or basement runs usually means more time underneath, in tighter space, with segments that were modified over the years and have to be traced. That takes longer than a newer attic flex system where the runs are visible and reachable. Number of supply and return openings matters, as does whether there's one system or several. Shared residences and buildings with near-continuous fan circulation also tend to hold more loading than a house that only runs AC a handful of weeks. We'd rather look at the system before committing to a figure than guess from the square footage.
