Heat pumps in Arizona
Arizona is ninth in the country at 26.4% of homes, which surprises people who think of heat pumps as a cold-climate technology. It is the opposite: Phoenix averages a 106°F high in the warmest month, every home needs cooling, and a heat pump is simply the air conditioner that also handles the mild winter.

What Arizona pays toward one
Efficiency Arizona
The state's federally funded rebate programme for efficient HVAC and appliances. It was warning of significant changes to its guidelines following federal action — applications were still open but under revised rules, so check the current terms first.

The IRA rebate programs (HEAR and HOMES) survived the 2025 tax changes — they were grants to states, not tax credits. Each state runs its own, and they are at different stages: some open, some already out of money, some yet to launch. Check where Arizona stands before you count on it.

The federal 25C tax credit — 30% back, up to $2,000 on a heat pump — ended for systems placed in service after 31 December 2025. If you had one installed in 2025 or earlier you can still claim it; there is no successor credit. Incentives move fast, so check DSIRE for what is current in Arizona. Last checked September 2026.

What a heat pump here has to cover

Cooling is the load that sizes the system here, and heating is the easy part — a heat pump covers it without breaking a sweat. The efficiency question is mostly about how hard the unit works in August, not January.
