Question 1

My Woodbridge house still has its original ductwork from the 70s. Is cleaning it even worth doing, or should I just replace it?

Accepted Answer

Cleaning is usually worth doing first, and it tells you what you actually have up there. A lot of the 1970s University Park, Turtle Rock, Woodbridge and Northwood homes have a mix of early flex branches off rigid metal attic trunks. The metal trunk sections clean up well and often outlast everything attached to them. The older flex is the question mark. If the inner liner has torn, sagged into a belly, or the outer jacket has gone brittle, we'll show you photos and tell you straight that cleaning that run is a short-term fix. Plenty of homes in those villages only need a few branches replaced, not the whole system.

Question 2

We're in Portola Springs and the attic is tight with long flex runs. Can you actually clean ducts like that?

Accepted Answer

Yes, and that layout is most of the newer Irvine work. Portola Springs, Cypress Village and the Great Park neighborhoods tend to put the air handler in a compact attic space with long flex runs snaking out to each room, so the cleaning is done mostly from the register side and at the plenum rather than by walking the attic. Long flex holds more dust along its ribbed inner wall than short rigid runs do, so it takes more passes. The tighter building envelope in these homes also means whatever gets into the system tends to stay in circulation. That's why owners of eight- and ten-year-old houses often see more than they expected.

Question 3

Why do my returns look dirty every spring?

Accepted Answer

Mature village landscaping. The eucalyptus, olive and ash planted across Irvine's older villages all drop heavy pollen in spring, and it finds the return side first. On top of that, Irvine sits inland on the flat basin without much marine moderation, so AC run hours are long and the system is pulling air through those returns far more of the day than a coastal home would. Add construction dust from the Great Park area and the 241/133 corridors and you get a return grille that greys over in a season. Spring is our busiest stretch here for that reason.

Question 4

What drives the cost up or down on an Irvine home?

Accepted Answer

Mostly system count and run length. A mid-rise or apartment unit with a closet air handler and short duct runs is the quickest job we do in Irvine and prices accordingly. A detached home in Northwood or Westpark with two systems and a register in every room is a different scope. The newer Great Park-area builds sit in between: one system, but long flex runs and a cramped attic that slows access. Age matters too. A 1970s home where we find damaged flex adds a repair conversation that a 2018 house usually doesn't. We walk the house and tell you the number before we touch anything.

Question 5

How fast can someone get out here, and do you ever do same-day?

Accepted Answer

Same-day happens, more often early in the week and more often in winter than in spring. From April through early summer we're booked heavier because of the pollen season and the start of real AC demand, so a day or two out is more realistic then. Condo and apartment units with a single closet air handler are easier to slot in late in the day since the work is shorter. If you're in a building with HOA access rules or a shared garage entry, tell us when you book. Sorting that out ahead of time is usually what decides whether same-day is possible.
