Layout-driven duct assessment
The remodel layout is checked against existing duct routes, registers and returns, and the duct changes the new layout actually requires are listed — no more, no less.

HVAC Ductwork Modification During Remodels in Los Angeles
This is renovation-supporting work, not a standalone heating and cooling service. When a remodel opens walls, moves rooms or changes layouts, ductwork often has to move, resize or seal with it — and that work is scoped inside the remodel, while walls are open and inspections are already scheduled. This page explains that supporting scope honestly, and what it does not cover.
Careful work. Honest options.
About this service
HVAC Ductwork Modification in Los Angeles: Support Work Only
During a remodel, ductwork modification means rerouting, resizing, extending or sealing ducts to serve a changed layout: a moved kitchen or bathroom, a new room, a converted garage or an opened wall that exposes existing ducts. Duct leakage testing is required on alteration work under Title 24, and HERS rater verification applies where the alteration triggers it — both are scoped into the remodel rather than treated as extras. Standalone heating and cooling installation, repair and servicing are not part of this scope.
Duct costs inside a remodel vary by layout change, duct length, sealing scope and verification triggers; pricing is set out in a written estimate after the site visit. The supporting scope below is what a remodel's written estimate should itemise for ductwork.
- ✓ Only inside a remodel scope
- ✓ Duct moves tied to layout changes
- ✓ Sealing and leakage testing included
- ✓ HERS verification where triggered
What's included
What Renovation-Supporting Ductwork Covers
Ductwork inside a remodel covers the supporting stages below. A heating or cooling system replacement, a new system installation, or a repair call is a different scope and is not covered here.
Rerouting and resizing
Ducts are rerouted around new walls, resized for changed rooms, and extended into additions or conversions where the remodel scope calls for it.
Sealing
Duct joints and connections are sealed as a system, since leaking ducts waste conditioned air into attics and wall cavities.
Leakage testing
Duct leakage testing is carried out as Title 24 requires on alteration work, with results checked against the applicable standard for the scope.
HERS verification where triggered
Where the alteration triggers HERS verification — for duct leakage, airflow or fan measures — a HERS rater is budgeted into the remodel, not discovered at final inspection.
Registers, returns, final check
Registers and returns are set for the new layout, airflow is checked room by room, and the duct scope is walked against the remodel's written scope.
How it works
How Remodel Ductwork Runs, Step by Step
The remodel layout and existing ducts are assessed together, and the duct changes the layout requires are written into the remodel scope.
Duct work follows the remodel's LADBS permit path, with mechanical inspection points scheduled alongside framing, plumbing and electrical.
Ducts are rerouted and sealed while walls are open, and leakage testing is carried out before finishes cover the work.
HERS verification is completed where the alteration triggers it, before finishes close the relevant work.
Registers and returns are set for the new layout, airflow is checked, and the duct scope is walked against the remodel scope.
STEP 01Layout assessment inside the remodel
The remodel layout and existing ducts are assessed together, and the duct changes the layout requires are written into the remodel scope.
Tools & methods
Tools and Methods We Use on Ductwork
Duct layout planning
Duct routes are planned from the new layout, with runs kept short and straight where the structure allows, so airflow reaches the rooms it serves.
Sealing materials and methods
Joints, connections and penetrations are sealed as a system, since a single unsealed joint can waste the sealing done elsewhere.
Leakage testing equipment
Duct leakage is measured, not guessed, so the remodel's Title 24 compliance is demonstrated rather than assumed.
Airflow checking
Room-by-room airflow is checked after registers are set, so a moved room is not left starved of conditioned air.
Protection during the remodel
Ducts are protected and capped during demolition and drywall work, so debris does not enter the system before handover.

Problems we solve
Remodel Ductwork Problems That Surface During the Work
Ductwork fails when it is treated as an afterthought to the remodel. These are the problems to scope for.
Ask a pro →Ducts that do not serve the new layout
A moved wall or new room without a duct plan leaves rooms starved of air. Duct layout is drawn from the new layout, not the old one.
Leaking ducts hidden by finishes
Ducts sealed after drywall cannot be tested or fixed properly. Sealing and leakage testing happen while walls are open.
HERS verification discovered at final inspection
Verification triggers that surface at final inspection delay handover. Triggers are identified during remodel scoping, with a rater budgeted in.
A remodel that needs system work beyond ducts
Where the remodel reveals a system that needs replacement rather than duct modification, that is a separate scope with its own licence and permit path — it is not folded into ductwork silently.

No, as presented here. It is renovation-supporting work inside a remodel: duct moves, resizing and sealing that a changed layout requires. Standalone heating and cooling installation, repair and servicing are not part of this service.
Duct work inside a remodel follows the remodel's LADBS permit path, with mechanical inspection points. The exact path depends on the remodel scope — confirm it against current LADBS rules.
Duct leakage testing measures how much conditioned air escapes from ducts, as Title 24 requires on alteration work. It is carried out before finishes cover the ducts, with HERS verification where triggered.
Duct-only work is a different scope from the renovation-supporting work described here, with its own licence, permit and system considerations. Duct-only work is handled as part of a remodel, not as a separate service.
