What is different about dryer vent cleaning in San Francisco
- San Francisco's stacked-flat housing routes dryer ducts vertically through the building to reach a roof or upper-wall termination, rather than horizontally to a ground-level exterior wall.
- A vertical run works against gravity, so lint that stops moving falls back down the duct and accumulates at the bottom of the run rather than distributing along it.
- Many San Francisco laundry installations were retrofitted into buildings constructed long before in-unit laundry existed, producing duct routes improvised through whatever cavity was available.
Vertical Runs Accumulate at the Bottom
This is mechanically different from the suburban case and it matters. In a horizontal duct, lint settles gradually along the length. In a vertical duct, lint that is not carried all the way up falls back.
The result is accumulation concentrated at the bottom of the run, right behind the appliance, building into a dense plug rather than an even coating. That is why San Francisco dryer ducts can go from working acceptably to barely working over a fairly short period — the restriction is concentrated rather than gradual.
Retrofitted Into Buildings That Never Expected It
A building constructed in 1908 had no provision for in-unit laundry. When a washer and dryer were added decades later, the duct went wherever a route could be found — up a disused flue, through a light well, along a corridor ceiling.
Those improvised routes are frequently longer, bendier and less accessible than anything a manufacturer envisaged. Establishing where the duct actually goes is sometimes the first useful part of the job, particularly in a building where several units have done the same thing independently.
Check Where It Terminates
In a multi-story San Francisco building this genuinely goes wrong. A duct that terminates in a light well, a shared corridor, an attic space or a wall cavity rather than outside is discharging warm moist lint-laden air into the structure.
In a detached house that causes a moisture problem for one household. In a shared building it can cause one for several, and it is the sort of fault that persists unnoticed for years. This is entirely separate from chimney work, despite the two frequently being sold together.
