IECC 2021Zone 2A — Hot-Humid

Texas climate and heat pump sizing

Texas is classified as IECC 2021 Zone 2A — Hot-Humid. Typical winter design temperatures are 25°F to 40°F.

Mild winters mean a standard ASHP is efficient and cost-effective. Cold-climate units (rated to -13°F) are not required.

Most 150A+ panels handle a heat pump without an upgrade. An NEC 220.82 check confirms headroom for your specific load profile.

Frequently asked questions — Texas

How much does a heat pump cost in Texas?

In Texas, a whole-home air-source heat pump typically costs $5,000–$14,000 installed, depending on home size, system type, and contractor. Cold-climate models for zones like Zone 2A cost more but deliver lower operating costs. Combined rebates of up to $1,500 (state programs) can offset a significant portion of installed cost.

Is HEEHRA available in Texas?

Texas's HEEHRA program has not yet launched but is expected to open. Texas has not yet launched its HEEHRA program as of March 2026. Check with the Texas State Energy Conservation Office (SECO) for updates. IRA 25C tax credit expired Dec 31, 2025 — not available for 2026 installations. Check your state energy office for updates. Note: the federal IRA 25C tax credit expired December 31, 2025 and is not available for new 2026 installations.

What size heat pump do I need in Texas?

Texas falls in IECC 2021 Zone 2A — Hot-Humid. Typical winter design temperatures are 25°F to 40°F. Mild winters mean a standard ASHP is efficient and cost-effective. Cold-climate units (rated to -13°F) are not required. Sizing requires a Manual J load calculation — but as a rough rule, allow 20–30 BTU/h per square foot for older homes in Texas.

Do I need a panel upgrade for a heat pump in Texas?

Not necessarily. Most 200A panels in Texas have headroom for a heat pump under the NEC 220.82 Optional Method — which accounts for diversity of loads rather than peak simultaneous demand. A 100A panel is more likely to require an upgrade, especially if you also have an EV charger or electric range. Our free audit calculates your exact available capacity in 3 minutes using the same method your electrician would use.
