Question 1

My Eichler-style home has radiant slab heat and no attic — is there even ductwork to clean?

Accepted Answer

If the house still runs on the original radiant slab, there's no duct system at all, and nothing for us to clean. Many of these flat-roof homes picked up add-on forced air later, though, and that's where the work is. Those retrofits usually run through tight ceiling plenums or boxed chases rather than a walkable attic, so cleaning happens mostly from the register side, with the equipment feeding in from each opening. It's slower than a standard attic job and we'd rather look at the layout before telling you what's involved than guess over the phone.

Question 2

We barely run the AC here — does that mean the ducts stay cleaner?

Accepted Answer

It's the opposite of what people expect. The marine air keeps Mountain View cooler and foggier than places further inland, so systems cycle less and for shorter stretches. Dust that settles in a duct doesn't get moved along by regular airflow. It just sits, sometimes for months, and packs down in the low spots and boots. Then the first warm stretch or the first real heating run pushes all of it at once. Light use isn't the same as clean.

Question 3

What usually turns out to be the actual problem in older Mountain View houses?

Accepted Answer

In the Old Mountain View bungalows on raised foundations, it's often the underfloor runs: flex duct sagging between joists, crushed sections, or joints that have worked loose and are pulling crawlspace air instead of return air. On the 1940s–60s ranches, we see undersized or poorly sealed return paths and old boots that were never properly connected to the register. In add-on forced air through flat-roof chases, it's usually accessibility, a run nobody has touched since it went in. Cleaning helps, but if there's a disconnect or a crushed run, we'll tell you that's the real issue instead of just vacuuming around it.

Question 4

How fast can someone get out here?

Accepted Answer

Mountain View is easy for scheduling most weeks, and we can often get a crew out within a day or two. The variable is which part of town. Single-family work in Old Mountain View or the ranch neighborhoods is easy to slot in. Apartments and townhomes around North Bayshore and Castro take more lead time because we may need building access, a parking arrangement, or a time window cleared with management before we show up.

Question 5

Why would my quote differ from a neighbor's on a similar-looking street?

Accepted Answer

Access drives the number here more than square footage does. A ranch with a real attic and clear runs is the simplest case. A flat-roof home where everything has to be worked through ceiling registers takes longer for the same number of vents. A raised-foundation bungalow means crawlspace time. Unit count matters too. A condo or townhome with a compact system is on the lighter end. We'd rather see the system and the access before committing to a number, because the house, not the address, decides it.
