Question 1

My house was built in the 90s with the furnace up in the attic — is that duct run even worth cleaning, or is it past saving?

Accepted Answer

Usually worth cleaning, but we tell you honestly if it isn't. The R-4.2 builder flex that went into Aliso Viejo tracts from the mid-80s through the early 2000s is now 20 to 40 years old. Common problems are sagging runs between trusses, bends crushed where they leave the plenum, and boot collars that have worked loose at the ceiling. Cleaning restores a lot of airflow on a run that's just dirty. A run that's collapsed, torn, or has inner liner coming apart isn't a cleaning problem, and we'll show you photos rather than scrub a duct that needs replacing. Plenty of homes here are a mix: most runs fine, two or three bad ones.

Question 2

After Santa Ana winds we get a fine grit all over the house. Does duct cleaning actually help with that?

Accepted Answer

It helps, though it's not a one-time fix. Sitting on the ridgelines above Aliso Canyon, homes here take decomposed granite and dry chaparral dust straight off the canyon during fall wind events. That gets pulled in through the single oversized central return most of these floor plans have, and whatever gets past the filter settles in the supply runs and boots. Cleaning empties that reservoir so the system stops re-circulating last October's dust every time it cycles. Pairing it with a better-sealed filter slot and tightened boot collars does more than cleaning alone, since loose collars in a 130-degree attic pull attic air and dust directly into the duct.

Question 3

How soon can you get out here?

Accepted Answer

Normal weeks, within a couple of days. The two stretches that fill up fast are early fall right after the first Santa Ana event, when everyone notices the dust at once, and the May-start of cooling season when systems get switched over and people smell something musty. If you're calling in those windows, book a few days out. Attic furnace work also depends on daylight and attic heat. We schedule those jobs for mornings in the warm months rather than putting a crew in a 130-degree attic at 3pm, so the morning slots go first.

Question 4

Can you come out the same day?

Accepted Answer

Sometimes, yes, especially if a morning job finishes early. Call and ask rather than assume. One thing that affects it in Aliso Viejo: a large share of the housing stock here is attached townhomes and garden-style condos, and those often need HOA notice or scheduled access to a shared attic or equipment area. If that applies to you, same-day is less likely regardless of our schedule. Detached tracts with their own attic access are the easier same-day calls.

Question 5

What makes one Aliso Viejo house cost more than the neighbor's?

Accepted Answer

Mostly register count and how hard the attic is to work in. These are two-story, slab-on-grade homes, so every supply drops from an attic furnace to a ceiling register. The more registers, the more work. Beyond that: whether the attic has walkable framing or you're crawling the whole run, whether the return is one oversized central drop or something less standard, and how much repair the flex needs once it's open. If we find a sagging run or a boot collar leaking into the attic, sealing and resupporting it is separate from cleaning and we'll tell you before we do it. Condos and townhomes with shared or tight equipment closets can run differently than a detached tract home with the same register count.
