Ductwork installation and repair across the Bay Area

Ductwork problems are easy to miss because the symptom shows up as an uneven-temperature room, not visible damage — a crushed flex duct in an attic, a disconnected joint behind drywall, or runs that were never sized for the space they serve. NorTech verifies an active C-20 license before dispatching a provider to assess, seal, repair, or install ductwork, with an airflow test confirming the fix actually worked.

The real cost of leaky ductwork

Duct leakage in an unconditioned attic or crawlspace means you're paying to heat or cool that space instead of your living areas — a significant, ongoing waste that compounds every time the system runs. Sealing and repairing leaks is often one of the more cost-effective HVAC improvements available.

Sizing new duct runs correctly

A duct run sized for a different room or an assumption about airflow, rather than an actual calculation for the space it serves, is a common reason a newly finished room never quite reaches a comfortable temperature. Correct sizing during installation avoids inheriting that problem in a brand-new space.

Frequently asked

Ductwork Installation & Repair — common questions

The assessment includes an airflow and visual inspection of accessible ductwork to locate disconnected joints, crushed sections, and leaks before sealing or repair begins.

This covers both — repair of existing ducts where they're salvageable, and new installation where a run needs to be replaced or added. Scope is confirmed before work starts.

New ductwork installation typically requires a permit; your verified C-20 contractor handles that as part of the scope.

Yes — a 1-year workmanship warranty. If covered work isn't right within that window, it gets made right at no charge.

It depends on the extent of the issue and duct accessibility; your contractor will give a realistic timeline after the assessment.

Sealing significant leaks often improves system efficiency noticeably, though the exact savings depend on how much leakage was present.
