Question 1

We had ash on everything after the last fire event — does that actually get into the ducts?

Accepted Answer

Yes, and it's the most common reason we get called in Calabasas. Fine ash is small enough to pass a standard filter and it rides into the attic through roof vents and any gap in the duct envelope. On homes here with long flex runs through tall attics, that ash settles along the inside of the runs and in the returns, then gets pushed back into the house the first time the system cycles. If you've had visible ash on patios or cars, it's reasonable to have the returns and at least a sample of the supply runs inspected before you assume the ducts are clean. Filters loading up fast after a smoke event is another tell.

Question 2

I keep hearing scratching in the attic. Can you tell if rodents have been in the ductwork?

Accepted Answer

We can, and on canyon-adjacent properties it's worth checking. Rodents chew into flex duct at the collar or along a sagging run, nest in the insulation, and leave droppings and urine inside the duct where airflow carries the smell into bedrooms. Cleaning alone doesn't fix that. The damaged section has to be replaced and the entry point sealed, or they come back to the same spot. During inspection we note torn runs, disconnected boots, and droppings so you know whether you're looking at a cleaning or a repair plus cleaning.

Question 3

Our house has three separate systems. What does that mean for the job?

Accepted Answer

It means more time and more access points. That's normal for the larger two-story homes built here from the 1980s onward. Each air handler has its own returns, its own supply trunk, and often its own zoning dampers, so they're cleaned as separate systems rather than one. Plan on a longer appointment than a single-system house. We'll also tell you honestly if one system is clean and another isn't. Upstairs units serving long attic runs usually need more attention than a downstairs system with shorter runs.

Question 4

What drives the price up or down on a Calabasas home?

Accepted Answer

Mostly system count and run length. A two-story home with two or three air handlers and zoned flex pushing to far corners of the house has considerably more linear footage and more registers than a small single-system home, and that's what the number tracks. Attic access matters too: tight, low-clearance or steeply pitched attics slow the work. Heavy ash loading after a fire event can add a step, since returns and filter housings may need more than a routine pass. We walk the attic and count systems and registers first, then give you the number before anything is touched.

Question 5

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

Accepted Answer

Same-day is sometimes possible, usually for single-system homes or inspections rather than a full multi-system clean, which needs a solid block of time. Most Calabasas appointments land within a couple of days. The exception is the window right after a wildfire or heavy ash event. Everyone in the foothills calls at once, and scheduling stretches. If you're smelling smoke indoors or there's a rodent problem in the ducts, say so when you call so we can prioritize it. Hillside driveways and gated access are routine for us; just let us know if there's a code or a narrow approach.
