Utilities in Arizona with nothing to claim

We check these and they pay nothing toward a heat pump today. They are listed rather than dropped, because if you are here looking for one of these names then this is your answer, and an empty page would read as an oversight instead of a result.

APS (Arizona Public Service)

Program ended

APS discontinued its residential efficiency heat pump rebates on 1 January 2026, so there is nothing here to claim from APS itself. Heat pump money in this market comes from the other Arizona programs your address qualifies for, and your quote prices only what you can actually get.

Utility programs in Arizona

These are the named utility and ratepayer rebates on file for Arizona. You claim the one that serves your address, not the total. Each card carries the program’s own terms: what equipment qualifies, who is eligible, what the cap actually is, and whether it stacks.

$720

maximum

Instant, taken off the priceTiered by efficiency

This one is already inside your quoted price. A participating contractor takes it off at the point of sale, so do not budget for it a second time as money arriving later.

Who qualifies, and the cap: TEP residential customers (Tucson). Must use a participating Efficient Home Program contractor; retire an older working or non-working unit.
Stacking: Instant rebate off purchase price; HPWH $400 and duct sealing are separate measures. Income-eligible Efficiency Arizona pathway up to $14,000 is a separate track.

What your system should be sized for

A heat pump in Arizona should carry the house on the coldest design day, not the average one. These are the winter design temperatures our engine sizes against, in AHRI heating region II (1,100 heating degree days at the Phoenix reference metro).

City	Design temp	Climate zone	Basis
Phoenix	37°F	2B	estimated
Tucson	31°F	2B	estimated
Flagstaff	3°F	5B	estimated
Prescott	15°F	4B	estimated

Rebate amounts are estimates and subject to change. Verify current program terms and eligibility before quoting a final net price.
Eligibility varies by income, equipment efficiency, utility territory, and program funding availability.
State and utility programs only. Federal 25C/25D tax credits expired 12/31/2025 and the DOE HEAR/HOMES rebate programs ended 5/29/2026; neither is included.
After-install rebates are claimed by the homeowner after installation and are not guaranteed at the point of sale.
