What Does Duct Replacement Cost in Sacramento?
Most Sacramento homes need new ducts every 20 to 25 years. Flex duct costs less to install. Sheet metal lasts longer. Fresh Air has done 900-plus installs since 2009. We pull a duct leakage test on every job. That test shows exactly how much air you are losing. It takes about 30 minutes and changes the whole scope of work.
Sheet Metal Duct Replacement
Sheet metal runs $10 to $15 per foot for materials. Full replacement costs $4,000 to $7,000 installed. Sheet metal holds its shape and lasts 30 or more years.
Duct Leakage Test
Fresh Air runs a leakage test at every HVAC estimate. The test finds splits, disconnected joints, and mastic gaps. We show you the results before we quote any work.
What Affects Your Duct Replacement Cost
- Home size — larger square footage means more linear feet of duct.
- Attic access — tight or low attics add labor time and cost.
- Duct material — flex duct costs less than sheet metal upfront.
- Number of zones — multi-zone homes need more supply and return runs.
- Existing damage — crushed or disconnected sections raise scope.
- Permit fees — Sacramento County requires a permit for full duct replacement.

Ductwork Replacement Cost Sacramento 2026 FAQ
How long does duct replacement take?
Most Sacramento homes take one to two days. Larger homes or tight attic access can add a day. We aim to finish in about 48 hours.
Can I replace ducts without replacing the HVAC unit?
Yes. Ducts and the air handler are separate systems. If your unit is newer, replacing just the ducts can restore full airflow and cut energy waste.
Does Fresh Air offer free estimates for duct work?
Yes. We offer free estimates for duct replacement and for full HVAC systems. The estimate includes a duct leakage test at no extra charge.
Will new ducts lower my energy bill?
Yes, in most cases. Leaky ducts can waste 20 to 30 percent of conditioned air. Sealing or replacing them improves system output and lowers run time.
