Question 1

My house has three air handlers on different zones. Do you have to clean all of them at once?

Accepted Answer

No, but it's usually the sensible way to do it. Multi-zone homes here often have two to four separate systems, and each one has its own supply trunk, returns and blower. Cleaning one zone does nothing for the air in the wing served by another. That said, if one zone is clearly the problem (the downstairs rooms that never smell right, or the bedroom wing over the crawl space), we can scope and clean that system alone and leave the others for later. We'll tell you what we find in each before you decide.

Question 2

We keep finding droppings near a floor register. Can duct cleaning fix that?

Accepted Answer

Cleaning removes what's in the ducts, but on wooded lots it's almost never the whole job. Rodents get into crawl space and attic ductwork through torn flex, open boot connections, and gaps where runs pass through framing, and they'll come straight back to a cleaned duct if the entry is still open. We inspect the runs, show you where the breach is, and clean and sanitize what's contaminated. Repairing or replacing the damaged flex section and sealing the entry point is what actually ends it. We'll be straight with you about whether that's a patch or a replacement of the run.

Question 3

What usually goes wrong with the ductwork in homes like ours?

Accepted Answer

Long flex runs are the recurring issue. A lot of the 1960s–80s custom builds, and some newer rebuilds too, push air a long way from one air handler to scattered rooms. Over the years flex sags between supports and debris settles and stays at the low points. You also get crushed or kinked sections where someone worked in the crawl space, disconnected boots at registers, and insulation jackets that have degraded in a hot attic. We note all of that during the inspection, because cleaning a run that's sagging badly just buys you a few years before it loads up again.

Question 4

How soon can you get out here, and do you ever do same-day work?

Accepted Answer

Same-day happens, usually when there's an opening or you're close to a job we're already on in the area. Most Los Altos Hills homes are booked a few days out, mainly because the scope here is bigger than average: several systems, long runs, crawl and attic access. So we block more time per visit rather than squeezing one in. Urgent situations like a rodent contamination or smoke that's gotten through the system get moved up. Call and we'll tell you honestly what the next real opening is instead of promising today and rescheduling.

Question 5

Why would cleaning cost more here than at a smaller house?

Accepted Answer

It comes down to how much duct there actually is and how hard it is to reach. A single-system tract house is one blower, one trunk, a short run list. An estate here may be three or four air handlers with long runs threading through a hot attic and a low crawl space, which means more access points, more time under the house, and more return and plenum work. Dry oak woodland, grass pollen, catkins and dust off unpaved drives also mean heavier loading, so systems here often need the full run cleaned rather than a quick register-level pass. We walk the house and count the systems and runs before we quote anything.
