Question 1

Our old sheet metal ducts in the crawlspace are rusting and the joints are coming apart — is cleaning worth it, or should we just replace the runs?

Accepted Answer

It depends on what the duct is doing structurally, and we'll tell you honestly after we look. On a lot of the older Woodside houses, the sheet metal trunk in a deep crawlspace is still solid and only the branch takeoffs or the tape at the seams have failed from years of damp. That's worth cleaning and sealing. Where the metal has rusted through at the bottom, or where a crawl run has sat in damp shade long enough to grow mold on the interior dust layer, cleaning buys you little and we'll say so rather than take the job. Same logic on newer flex in the attic: if the inner liner is torn or crushed behind an insulated sleeve, no cleaning fixes that run.

Question 2

How long does it take to get someone out to a Woodside property?

Accepted Answer

Usually a few days out, sometimes longer. Woodside jobs take more of a crew's day than a flat suburban lot does, between the driving on the hill roads and the fact that a lot of properties here have a long private drive, a gate, and a crawlspace access that isn't right by the door. If you've got dogs loose, horses in a paddock near where we'd park, or a gate code, tell us when you book and we'll plan the window around it. After a bad smoke stretch in late summer or fall the calendar fills up quickly, so call earlier than you think you need to.

Question 3

What actually goes wrong with duct systems up here?

Accepted Answer

A few things repeat. Damp is the big one. Dense canopy, winter rain, and a crawlspace that never fully dries means dust sitting on duct surfaces stays moist, and that's where mold gets started. Second is loading from outside: redwood duff, oak and pine litter, pollen, and on horse properties the fine arena and barn dust that rides in on clothes and boots and ends up packed in the returns. Third is wildfire smoke, which puts a fine ash layer through the whole system during the late summer and fall months and keeps reintroducing a burnt smell every time the blower runs. On newer multi-zone flex installs we also find runs kinked or disconnected at the boot in the attic, which looks like a dirty-duct problem but isn't.

Question 4

Can you ever do same-day work?

Accepted Answer

Occasionally, when a crew is already working on this side of the mountains and a slot opens. It's not something to count on for Woodside specifically. The travel in and out plus long driveways makes it hard to slot a last-minute job without pushing someone else. If it's urgent, say a smell after a smoke event or something visible at a register, call and we'll tell you straight whether there's a realistic opening that day or whether it's a two or three day wait.

Question 5

Why would a quote here come in higher than at a house down in the flats?

Accepted Answer

Mostly scale and access. Woodside houses run large and often have more supply runs than a comparable home elsewhere, and multi-zone systems in newer builds mean more than one air handler to clean. On the older homes, the work happens in a deep crawlspace or basement where the crew is moving on their back with lights, which is slow. Add the private drive and gate time, and sometimes a second visit if the crawl is too wet to work in that week. On the other side, a small 1920s or 50s cottage with one short system and reasonable access is a straightforward job and prices like one. We walk the property and the crawl or attic before we put a number on it, so what you see reflects your actual layout, not an average.
