APS Cool Rewards Smart Thermostat Guide for Arizona Homeowners

APS customers who already own — or plan to buy — a smart thermostat should check the Cool Rewards program before purchase or enrollment. The program can reduce upfront or annual costs, but the details depend on device eligibility, enrollment path, event season timing, and APS program availability.

What APS says to verify

APS describes Cool Rewards as a demand-response program for smart thermostats during high-demand summer periods. The official APS page says conservation events may occur during the June 1 through September 30 season, and that eligible participants may receive a one-time enrollment credit plus an annual participation credit while the program is available.

Questions to ask

1. Is this exact thermostat model eligible right now?

2. Will the one-time credit appear at purchase or on a later APS bill?

3. When is the annual participation credit paid?

4. How many thermostats at this service address can qualify?

5. Can I leave or override events without losing eligibility?
