Ductwork installation includes designing the duct layout for proper airflow distribution, fabricating and installing trunk lines and branch runs using sheet metal or flex duct, sealing all connections with mastic and foil tape, insulating ducts in unconditioned spaces, and installing registers and grilles. Properly designed and sealed ductwork is critical for HVAC efficiency — leaky ducts can waste 20-30% of conditioned air. This estimate covers new installations and full replacements using NorCal 2025-2026 pricing.

Codigo de Construccion de California

California Title 24 mandates R-6 minimum duct insulation in unconditioned spaces, mastic sealing at all joints, and HERS-verified duct leakage testing. Maximum allowable leakage is 5% of system airflow for new installations.

Cronograma del Proyecto

Design & layout

2-4 hours

Measure rooms, perform airflow calculations, design the duct layout with proper trunk and branch sizing, and determine register placement for balanced airflow.

Trunk line fabrication & installation

1-2 days

Fabricate the main trunk lines from sheet metal, install in the attic or crawl space, and hang with proper support straps at required intervals.

Branch runs & register installation

1-2 days

Run branch ducts from the trunk to each room, cut in register boots, and install supply registers and return air grilles.

Sealing, insulation & testing

4-6 hours

Seal all duct joints with mastic and foil tape, wrap exposed ducts with R-6 insulation, and perform a duct leakage test to verify compliance with Title 24 standards.

Ductwork Installation en Morgan Hill — Preguntas Frecuentes

Should I use sheet metal or flex duct?+

Sheet metal ducts offer better airflow and durability but cost more. Flex duct is economical for branch runs but must be pulled tight with no kinks. Most Sacramento installations use sheet metal trunks with flex branch runs — a good balance of cost and performance.

How do I know if my existing ducts need replacement?+

Signs include uneven temperatures between rooms, excessive dust, visible duct deterioration, age over 15-20 years, or high energy bills. A duct leakage test can quantify how much conditioned air you're losing.

What is duct leakage testing?+

California Title 24 requires duct leakage testing on new installations. A HERS rater pressurizes your duct system and measures air loss. Ducts must leak less than 5% of total airflow to pass inspection.

How long does ductwork installation take?+

A full ductwork installation for a 1,500-2,000 sq ft home typically takes 2-4 days. Simple replacements or partial runs can be completed in 1-2 days.
