Air Duct Replacement in Los Gatos for Cleaner, Healthier Air

Air duct replacement means removing old, damaged, or contaminated ductwork and installing new, properly sized, sealed, and insulated ducts. It’s usually recommended when ductwork is leaking, crushed, disconnected, contaminated by rodents, or simply too old to perform well. During your free inspection, we’ll show you photos and measurements so you can clearly see whether replacement is necessary.

Cleaning can help when ducts are structurally sound but dusty. Replacement is often the better choice if you have torn or disconnected ducts, poor airflow to certain rooms, musty or rodent odors, visible mold, or insulation falling off. We’ll inspect your system and explain whether cleaning, partial replacement, or full air duct replacement is the smartest investment for your home.

Yes. In most cases, we keep your existing furnace, AC, or heat pump and simply redesign and replace the ductwork so it matches your equipment and home layout. We connect new ducts to your current supply and return vents, test airflow, and make adjustments so your system runs more efficiently and comfortably.

The cost depends on your home’s size, the condition of the existing ducts, how accessible they are (attic, crawl space, tight areas), and whether we’re doing a full or partial replacement. We don’t give one-size-fits-all pricing online, but we do provide a free in-home inspection and a clear, itemized estimate before any work begins—no surprises.

In most cases, yes. New, properly sealed and insulated ducts reduce dust, allergens, and contaminants being pulled into the system, and they prevent conditioned air from leaking into unconditioned spaces like attics or crawl spaces. Homeowners often notice more even temperatures, less dust, and lower energy bills after a professional air duct replacement.

Most projects are completed in a single day, with larger or more complex homes sometimes taking two. We protect floors and living areas, bag and remove old ductwork, and clean up our work areas before we leave. At the end, we walk you through the new layout, show you before-and-after photos, and answer any questions about your new duct system.
