Question 1

My house is a 1950s ranch on a slab with the ducts up in the attic — does that change how you clean?

Accepted Answer

It changes the access more than the method. On slab ranches the whole run lives overhead, so we work from the registers and from the attic itself, and the condition we find varies depending on whether the original ducting was ever replaced. Older flex in a hot Sunnyvale attic can be brittle, sagging between joists, or pulled loose at a boot, and that gets found during the work rather than guessed at from the ground. We'd rather tell you a run is torn than blast air through it and spread what's in there. If your attic has low clearance over the bedrooms, say so when you call so we plan the approach.

Question 2

We've had the windows open every evening since spring. Is that why everything feels dusty?

Accepted Answer

Probably part of it. The evening breeze through the valley is one of the nicer things about living here, and it also carries outdoor dust and pollen straight into the house, where it settles and then gets picked up by the system when the AC runs hard the next afternoon. Supply registers and the return grille are usually where you see it first. Duct cleaning clears what has already accumulated inside the system. Keeping a decent filter in and changing it on schedule is what keeps it from rebuilding as fast.

Question 3

We just finished an addition and an ADU in the back. Should we clean the ducts now or wait?

Accepted Answer

Wait until the dusty trades are done: drywall hanging, sanding, and any floor work. That fine white dust is the most common thing we pull out of older Sunnyvale tracts, because the remodel and ADU work in those neighborhoods never really stops. It's light, it travels, and it coats the inside of ducts and the blower wheel even when crews tape off the registers. Cleaning before the sanding is finished means doing it twice. If the system ran during construction, mention it, since the blower and coil usually need attention too, not just the ducts.

Question 4

What actually drives the price on a job here?

Accepted Answer

Mostly the layout and the number of openings. A single-story ranch with attic ducts and a long run of registers takes more time than a townhome or apartment with a short ducted fan coil and a closet return, so those two sit at different ends of the range. Other things that move it: how many returns you have, whether the attic is tight to work in, whether there's construction dust loading on top of normal buildup, and whether anything is torn or disconnected and needs attention before cleaning makes sense. We look at the system and explain what it takes before we start. No charge to walk it with you.

Question 5

How soon can you come out, and is same-day ever possible?

Accepted Answer

Most Sunnyvale jobs get scheduled within a few days. Same-day happens when there's a cancellation or an opening in the area we're already working, so call early in the day if that's what you need and we'll tell you honestly whether it's realistic. Multifamily units along El Camino and near the Caltrain corridor are usually quicker to fit in because the ducting is short. If it's a rental, we need building or HOA access arranged first, and that's often the part that sets the timeline rather than our schedule.
