Why It Matters

When ductwork fails — cleaning won't fix it.

Flex duct has a 15-20 year life. After that, the inner liner crumbles, insulation compresses, and seams separate — pumping conditioned air into your attic instead of your rooms. Cleaning a duct that's already failing is throwing money at the wrong problem.

Replacement restores full airflow, lowers your California energy bill by 15-30%, eliminates musty smells from torn insulation, and gives you a fresh 15+ year start with a documented warranty.

  • Restored full airflow — new ducts properly sized and sealed deliver every cubic foot of conditioned air to your rooms.
  • Lower California energy bills — typical 15-30% reduction in HVAC runtime after replacement.
  • Better indoor air quality — new sealed ductwork blocks attic dust, fiberglass particles, and rodent contamination.
  • 10-year material warranty — comprehensive coverage in writing on all new ductwork.

Frequently Asked

About duct replacement.

Specific questions about duct replacement. For general questions, see the main FAQ.

How do I know if my ducts need replacement vs. cleaning?

Signs you need replacement (not cleaning): visible mold inside the duct, crushed or torn sections, musty smell that returns after cleaning, ducts over 15-20 years old, weak airflow at registers despite filter changes. Our free assessment confirms which is right for your home.

How long does a full duct replacement take?

Most California single-family homes complete in 1-2 days. Larger homes or complex routing may take 3 days. We give a precise timeline in your written quote — no schedule surprises.

What kind of ductwork do you install?

R-8 insulated flex duct (UL-181 listed) for most residential applications — the California energy code standard. Sheet metal trunks where structurally required. All joints sealed with UL-181 mastic, not just tape. Material specs in your written contract.

Will my energy bills go down?

Typically yes — California homes with failing ductwork see 15-30% lower HVAC bills after replacement. The exact number depends on how leaky the old system was and how often you run AC/heat. We document before/after pressure tests so you can verify.

Do I need permits?

For partial replacement (replacing failed sections), usually not. For full system replacement in most California cities, yes — and we handle the permit application, inspection scheduling, and final sign-off on your behalf. Included in the quote.
