Austin, Texas · New supply-and-return installation
Plan a new duct system for a home or addition that needs new distribution runs. Start with the room layout, supply and return paths, and written inclusions—not a citywide price per foot.
Budget reference, with its limits
Our existing national planning model gives about $5,900–$12,700 for a complete 2,000 sq ft system with attic routing, a standard layout, two return-air locations, and no finish-repair allowance. This is not an Austin market average or a local contractor quote. No Austin multiplier has been added. Smaller branch extensions and complex retrofits need their own scope.
Review the national model and adjust its assumptionsReviewed November 4, 2026. Clear HVAC Costs is an independent planning resource; we do not install ducts or operate a local Austin contracting office.

Keep a first duct system, a limited addition, and removal-and-replacement bids in separate comparisons. Cleaning, sealing an existing system, and repairing a disconnected run are different jobs.
Ask for the supply and return layout before routes are enclosed. Identify which rooms, registers, air handler, and return paths the price serves.
A small addition is not a whole-home system. Verify whether the existing equipment can serve the added rooms before agreeing to connect new branches.
Request a route plan showing attic or interior runs, access openings, supports, insulation, and where new returns will go.
Separate duct construction from HVAC equipment, electrical work, structural openings, and wall or ceiling restoration. They may require other trades.
List removal, disposal, reconnection, and any suspected hazardous materials separately from the new system.
This is a replacement scope. Use our replacement guide rather than treating a new-installation planning allowance as a removal-inclusive bid.
For existing ducts that must come out, review ductwork replacement costs. For equipment plus distribution, use the Austin HVAC cost guide and ask for separate equipment and duct totals.
Address and complete scope come first
Confirm the property’s permitting jurisdiction; an Austin mailing address or ZIP is not enough. The City’s Types of Permits page lists residential building permits for new construction and additions, alongside separate mechanical change-out and repair categories. A new duct design is not automatically a qualifying equipment change-out.
Use the City’s standalone permit guidance to ask whether the whole project qualifies for that route or belongs with a building permit. Have the responsible registered trade contractor identify the required mechanical permit, associated work by other trades, inspection stages, and who schedules them. Request the applicable permit record before work starts.
These official sources support the permit questions, not a dollar allowance. This guide does not set permit fees, decide exemptions, or promise an approval time. Confirm current requirements with the authority for the actual address.
The City’s contractor selection guidance recommends comparing at least three bids for the same work and checking trade credentials and permit status. Use identical rooms, routes, return locations, insulation, sealing, testing, and finish responsibilities in each request.
| Proposal | Written amounts | Comparable total? |
|---|---|---|
| A: low headline | $6,000 base; returns, testing, finish work, and permits unspecified | $6,000 is an incomplete subtotal. Do not treat unknowns as $0. |
| B: written allowances | $6,000 base + $800 insulation/sealing + $500 testing + $900 finish + $300 permit allowance | $8,500 illustrative subtotal. Confirm returns, taxes, allowance limits, and exclusions. |
| C: bundled proposal | $8,200 package; the same listed work confirmed included in writing | $8,200 only compares after the design and included work match B. |
The $300 above is a made-up allowance to demonstrate addition, not a City of Austin fee. None of these examples establishes a fair local market price or ranks an actual contractor.
Use the contractor’s amounts
Enter each charge once. For an add-on already included in the base, enter 0 only after the contractor confirms that in writing. Leave an unknown charge blank. This worksheet adds your figures; it does not estimate local labor rates, size ducts, or send your entries to a contractor.
New installation service fit
Current partner priority records reviewed November 4 include Install new ductwork for Austin ZIP examples 78701, 78702, 78703, 78704, and 78705. These examples are not a complete service map. A listed ZIP does not establish property eligibility, permitting jurisdiction, or guaranteed contractor availability; an unlisted ZIP here is not automatically excluded.
In Brief Description, specify whether this is a complete first-time supply-and-return system or new runs for an addition, the rooms served, approximate area, routing access, and whether equipment is already present. The form does not automatically select a new-duct subtask. If old ducts must be removed, say so and ask the partner to confirm that the replacement scope is accepted.

Ask for room loads, the selected equipment’s airflow needs, a duct layout, return paths, and written startup checks. ENERGY STAR’s HVAC designer resources describe load, equipment-selection, and duct-design documentation for its certification programs. They are a useful reference for questions; this page does not claim that every Austin project is required to be ENERGY STAR certified.
The opening range comes unchanged from our national installation calculator. Its underlying example is approximately $5,855–$12,693 before rounding to hundreds. Equipment, major electrical work, structural changes, hazardous-material work, and unselected finish repairs are outside that example. Neither the official sources nor the ZIP inventory validates those prices as Austin transaction data.
The quote worksheet adds amounts you enter. It does not apply the national model or a local multiplier. Resolve blank items, allowances, taxes, demolition, and any other exclusions with the contractor before comparing final totals.
There is no verified Austin completed-job average on this page. As an initial reference, our national model produces about $5,900–$12,700 for a complete 2,000 sq ft system with attic routing, a standard layout, two returns, and no finish-repair allowance. That is a model example, not an Austin contractor offer. Get a measured, itemized local quote before setting a project budget.
No. A branch extension must be assessed against the existing equipment, supply capacity, and return-air path. The complete-system model linked here has minimum allowances and does not price an isolated extension. Ask for an addition-specific design and scope.
No. Confirm the project address and permitting jurisdiction. The City of Austin lists residential building permits for new construction and additions and separate standalone mechanical categories for qualifying work. Ask the responsible contractor which building and trade permits apply to the complete project.
Our partner’s current priority records include new ductwork installation for Austin ZIP examples such as 78701, 78702, 78703, 78704, and 78705. Enter the actual project ZIP and describe the job as Install new ductwork. Availability and acceptance are determined by the partner; a listed ZIP is not a booking or a guarantee.
Only if its written scope says so. Confirm the number of return paths, insulation and sealing specification, testing and balancing, access openings, finish repairs, permit responsibility, and exclusions. A lower headline total with unpriced work cannot be compared directly with an inclusive proposal.
