Question 1

My ducts under the house are original to the home — is cleaning them worth it, or should they just be replaced?

Accepted Answer

It depends on what the crawlspace tells us. A lot of East Palo Alto's small single-story tract homes got forced air added years after they were built, with the trunk and branches run under the floor. Some of that ductwork has been down there a long time. If the runs are intact, sealed at the joints, and the lining isn't deteriorating, cleaning them makes a real difference. If we open a duct and find crushed sections, separated joints sitting in damp crawlspace air, or flex that's gone brittle, cleaning it won't hold. You'd be paying to clean a duct that's pulling in crawlspace air anyway. We tell you which one you're looking at before we clean, not after. On homes still running a gas wall or floor furnace with no ducting at all, there's nothing to clean, and we'll say so.

Question 2

What usually turns up in ducts here that wouldn't show up elsewhere?

Accepted Answer

Two things, and they stack. Being this close to the bay margin and the marsh means high ambient humidity year-round, so dust in an under-floor duct doesn't stay loose and powdery. It cakes, and in systems that have sat untouched it can hold moisture. Then there's the 101 corridor right alongside town, which puts a steady load of fine road and brake-dust particulate into the air. That's the dark, fine grit people notice on registers and sills. Add salt air working on anything metal, and older sheet metal boots and furnace cabinets in this area show more corrosion than you'd expect for their age.

Question 3

What makes the cost go up or down on an East Palo Alto house?

Accepted Answer

Square footage works in your favor here. Most of the original tract homes are modest, single-story, with a short duct run and a small number of registers, which keeps the job on the smaller end. What drives it up is access and condition. Under-floor ducting in a tight or low crawlspace takes longer than attic work. Systems that haven't been touched in decades need more time at each run. And a lot of these homes have minimal return capacity, sometimes a single return, which changes how we have to set up to get real airflow through the system. We walk the crawlspace and count registers before quoting so the number reflects your house, not an average one.

Question 4

Can you come out same day?

Accepted Answer

Sometimes, and more often early in the week than late. East Palo Alto is a compact service area for us and we're usually working nearby, so a same-day slot opens up fairly often. The honest caveat: if your crawlspace access is tight or unknown, or we're not sure whether you're on ducted forced air at all, we'd rather schedule a proper window than squeeze in a visit and find we can't do the work that day.

Question 5

I'm in one of the newer apartment buildings — does duct cleaning apply to me?

Accepted Answer

Depends on your system. Units with ducted fan-coil distribution do have short duct runs worth cleaning, usually a small, contained system that goes quickly. Ductless mini-splits have no ducts at all. What those need is head and blower-wheel cleaning, which is a different service. Either way, check with your building management first. In multifamily buildings the air handling is often partly shared or covered under the building's own maintenance, and we don't want you paying for something that's already someone else's responsibility.
