HVAC Replacement Cost in Texas (2026)

HVAC replacement in Texas typically runs $7,400–$17,200 for a complete 3-ton system replacement, with natural-gas furnaces with central AC as the dominant heating choice and roughly 1,900 heating degree days against 2,900 cooling degree days driving the seasonal load mix. The February 2021 Uri freeze event (and 2022 December storm) exposed widespread heat-pump-only systems lacking emergency backup heat strips — Texas now sees aggressive dual-fuel HP + electric resistance backup or HP + gas furnace adoption statewide; Gulf Coast latent load remains the bigger annual driver, with Houston and Corpus Christi dewpoints over 75°F May-October.

How HVAC replacement costs vary in Texas

State-specific code or insurance rule: Texas TDLR Class A and Class B Air Conditioning & Refrigeration licenses are mandated under Texas Occupations Code Chapter 1302 with strict scope limits — Class B caps at 25-ton single-system tonnage and 1.5 million BTU heating, prohibiting commercial work — and post-Winter-Storm-Uri (2021), TDLR added a new Endorsement A pathway recognizing emergency dual-fuel design experience.
