# Texas HVAC Replacement Cost

> What drives HVAC replacement cost in Texas in 2026: climate zone and load, heating after 2021, the 14.3 SEER2 Southeast rule, TDLR licensing and permits.

## Key facts

- Texas sits in the Department of Energy's Southeast region for central air conditioner standards, so a split-system air conditioner installed in Texas must meet 14.3 SEER2 under 45,000 Btu/h or 13.8 SEER2 at 45,000 Btu/h and above, against a national manufacturing minimum of 13.4 SEER2 (10 CFR 430.32(c)(5) and (c)(6)).
- A TDLR Class B environmental air conditioning endorsement covers systems up to 25 tons cooling capacity or 1.5 million Btu per hour heating output; a Class A endorsement has no size limit (Texas Department of Licensing and Regulation).
- Since September 1, 2021 Texas Occupations Code Section 1302.304 prohibits a municipality from charging registration fees to TDLR-licensed air conditioning and refrigeration contractors, but does not prevent municipalities from collecting building permit fees (TDLR ACR FAQs).

## Data

- What moves a Texas HVAC replacement quote, 2026. Methodology: Cost-driver table, not a price table. We publish no dollar range for Texas because an honest one does not exist across a state that runs from the Panhandle to the Gulf: tonnage, equipment type, duct condition and location, electrical work, permit costs and access dominate, and they differ by hundreds of miles. The regulatory drivers below are sourced to the EPA, 10 CFR 430.32 and Texas TDLR and were checked on 2026-08-14. Take the last column with you to every quote appointment.
