How much does it cost to replace an AC system in Austin, TX?
Full AC system replacement in Austin, TX typically runs $6,500–$12,000 installed for a standard-efficiency system, including the outdoor unit, indoor coil, and labor.

What you can check yourself

- Compare like-for-like efficiency (SEER2 rating) across quotes.
- Ask about utility rebates and federal tax credits in the quote — good installers itemize them.
