Air Duct Cleaning in Boulder Creek, CA

That depends on what the duct is made of and how far gone it is. A lot of Boulder Creek homes are 1920s-40s summer cabins that were converted over the years, with duct strung through an open crawlspace under a pier foundation and little or no insulation around it. If the outer jacket is intact and the problem is dust, soot and debris, cleaning is the right call. If the internal fiberglass liner has broken down from years of damp, or a run has been torn open and nested in, cleaning won't fix it. You'd be scrubbing material that's already shedding into the air. We look at the runs first and tell you honestly which sections are worth cleaning and which ones need replacement before anyone starts.

Under the redwood canopy there's little direct sun and the crawlspaces stay damp for months. Duct running through that space sits cold, picks up condensation, and the dust inside it stays wet instead of drying out. That's where the musty smell comes from, and in older flex and fiberglass-lined duct it's often mold growth in the liner rather than loose debris. Cleaning removes the dust and contamination that feeds it, but if the crawlspace stays wet the smell will come back. We'll tell you what we see down there (standing water, missing vapor barrier, open vents) even though that part isn't duct work.

It's one of the most common things we find in the Valley. Crawlspaces here are open and easy to get into, and rodents and insects chew through flex duct jackets to nest in the insulation. Once a run is breached, the system is pulling crawlspace air, droppings and nesting material straight into the house every time the furnace runs. Cleaning handles the contamination inside the system, but the breach has to be sealed or replaced or it starts over. We check every accessible run for damage rather than just cleaning what's easy to reach.

Often, yes. Homes that survived the fire took in smoke and fine ash through every gap, and a forced-air system distributes and then holds that material in the ducts and at the return. Wood stove use on top of it keeps adding soot and creosote particulate, which gets pulled into returns and settles in the trunk lines. Cleaning the returns, supplies and blower compartment removes what's sitting in the system. We'll be straight with you about it: if the smell is also in carpet, drywall or insulation, duct cleaning reduces it but won't eliminate it on its own.
