Austin, Texas: HVAC Replacement Cost Calculator

Replacing an HVAC system in Austin typically runs $4,000 to $7,500 for a central air conditioner and $6,000 to $12,000 for a heat pump, installed. A matched AC and gas furnace changeout lands between $7,500 and $13,000, while a ductless mini-split system ranges from $3,500 to $10,000. Austin's labor costs sit about 9% below the national average, with HVAC technicians earning around $28.43 an hour, which keeps installed pricing a bit friendlier than in many large metros.

Worked example

Take a 1,900-square-foot single-story home in South Austin with original ductwork and a 15-year-old split system. The homeowner replaces both the condenser and the gas furnace with a matched, higher-efficiency pair sized for Austin's hot, cooling-dominant climate (Zone 2). Because the ducts are usable and no major electrical work is needed, the job lands near the middle of the $7,500 to $13,000 AC-plus-furnace range, call it roughly $9,500 to $10,500, plus a permit fee somewhere in the $75 to $300 window. Adding attic duct sealing or a full duct replacement would push the total toward the top of that range.

Frequently asked questions

How much does it cost to replace an AC unit in Austin?

A central air conditioner replacement in Austin generally costs $4,000 to $7,500 installed, covering both equipment and labor. Where you land depends on tonnage, efficiency rating, and whether your existing ductwork and electrical can be reused. If the indoor coil or air handler also needs replacing, expect to be in the upper half of that range.

Is a heat pump worth it in Austin instead of a gas furnace?

Austin sits in climate zone 2, where winters are mild and cooling dominates the year, so a heat pump can handle heating loads without much backup. A heat pump system runs $6,000 to $12,000 installed versus $7,500 to $13,000 for a new AC and gas furnace pair. If you are replacing both halves of an aging system anyway, a heat pump is worth pricing out side by side.

Are there HVAC rebates available in Austin?

Austin Energy offers home HVAC rebates with amounts that vary by system type and efficiency, and you can review current offers at savings.austinenergy.com/rebates. Oncor also runs residential HVAC incentives, but those are delivered through participating contractors rather than applied for directly. Ask any contractor you bid with whether they are enrolled in these programs before you sign.

Do I need a permit to replace an HVAC system in Austin?

Yes, HVAC changeouts in Austin require a permit, and fees typically fall between $75 and $300 depending on the scope of work. Your contractor should pull it as part of the job. Texas also requires HVAC contractors to hold a TACLA or TACLB license from the Texas Department of Licensing and Regulation, so verify the license number before hiring.
