What Texas Residents Should Know
Texas falls in IECC climate zone 2-3A with 1,800 heating degree days per year — well below the national average. With an average heating COP of 3.3, heat pumps in Texas operate at high efficiency, producing 3.3 units of heat for every unit of electricity consumed.
With natural gas at $0.85 per therm in Texas, a gas furnace may have lower operating costs in the coldest months. However, heat pumps provide both heating and cooling in one system, which can offset the difference when you factor in AC savings. In shoulder seasons (spring and fall), a heat pump is significantly more efficient, often making the overall annual cost competitive with gas.
A heat pump also replaces your air conditioner, and Texas's 2,800 cooling degree days make that dual-function value real: one system handles both seasons, so you retire a separate AC unit and its maintenance along with the furnace. For homes with an aging furnace-and-AC pair, replacing both at once is usually where a heat pump makes the strongest financial case in Texas.
Texas residents can access up to $1,550 in state rebates and incentives for heat pump installations. With the federal 25C credit having ended December 31, 2025, these state and utility programs are now the primary way to reduce the upfront installation cost, which typically ranges from $4,000 to $8,000 depending on system size and complexity.

Incentives in Texas
Federal clean energy tax credits ended in late 2025 under legislation passed in July 2025; they are shown below for reference since recent purchasers may still claim them. State programs are governed separately and many remain active — always verify current details with the program before purchasing.
| Incentive | Type | Amount | Description |
|---|---|---|---|
| Energy Efficient Home Improvement Credit (Heat Pump - 25C)Ended | tax credit | 30% | Federal tax credit of 30% up to $2,000 for qualifying heat pumps. Ended December 31, 2025 — systems placed in service after that date do not qualify. State and utility heat pump rebates remain available in many states. |
| CPS Energy Heat Pump Rebate (San Antonio) | rebate | $1,550 | Residential rebates of $90-$310 per ton for a qualifying heat pump based on efficiency. CPS Energy customers. |
Heat Pump Savings in Texas: Frequently Asked Questions
- Are heat pumps worth it in Texas?
- In Texas, low natural-gas prices mean a heat pump may not beat a gas furnace on heating cost alone, but its combined heating-and-cooling in one system, plus efficiency in mild months, can still make it the better long-term choice.
- Do heat pumps work in Texas's climate?
- Texas sits in IECC climate zone 2-3A with about 1,800 heating degree days per year. Modern heat pumps there average a heating COP of 3.3, meaning they deliver 3.3 units of heat per unit of electricity.
- Are there heat pump rebates in Texas?
- Yes. Texas residents can access CPS Energy Heat Pump Rebate (San Antonio), worth up to $1,550. The federal 25C credit ended December 31, 2025, so these state and utility programs are now the main way to cut installation cost.
