What Being an SRP Customer Means for Your HVAC Decisions
If your home is SRP territory, you're on the lucky side of the Valley's 2026 rebate map: SRP Cool Cash still pays $75–$225 per ton on qualifying AC and heat pump installs (up to $1,125 on a 5-ton variable-capacity system), duct test-and-repair is 75% covered up to $400, and smart thermostats earn ongoing bill credits — all verified against SRP's own program pages. The trade: SRP's time-of-day plans and demand charges make when you cool matter as much as how.
Which Valley homes are SRP homes?
SRP — Salt River Project — is the Valley's not-for-profit power utility, serving Tempe, Gilbert, most of Mesa, Fountain Hills, Apache Junction, and large parts of the split cities: south Scottsdale, roughly half of Phoenix, Glendale, Peoria, Chandler, Avondale east of the Agua Fria River, and the east side of Paradise Valley. The 1955 territorial line, not city limits, decides it — in Peoria and Glendale the utility can flip from one street to the next.
One special pocket: roughly 5.5 square miles around downtown Mesa is served by the City of Mesa's own municipal electric utility (since 1917) — SRP rebates don't apply there even though the rest of Mesa qualifies. It's exactly the kind of detail that makes us confirm the utility from your address before a single rebate dollar lands on a quote.

Rate Reality
SRP's current lineup gives you a flat option, a prepaid option, and two time-based plans that reward moving your cooling out of the evening. (SRP is also applying a temporary price reduction of $0.0038/kWh for the May–October 2026 billing cycles.) What each one means for your AC:
How do SRP's time-of-day plans change the HVAC math?
Conserve 6–9 p.m. and Save (E-28)
Super off-peak 8 a.m.–3 p.m. · on-peak 6–9 p.m.The supercooling plan. Mid-day energy is the cheapest SRP sells — in July and August the spread runs roughly 40¢ per kWh on-peak against under 7¢ super off-peak, about a six-to-one difference on SRP's own rate sheet. Cool the house hard through the cheap afternoon window, coast through 6–9 p.m., and the plan pays you for the discipline.
Manage Demand 5–10 p.m. and Save (E-16)
Lower kWh prices + demand charge measured 5–10 p.m.Cheaper energy all day in exchange for a monthly demand charge set by your highest usage during the 5–10 p.m. window. The AC compressor is the biggest single load in a Phoenix home, so pre-cooling before 5 and staggering the oven, dryer, and pool pump directly shrinks the demand line on the bill.
SRP Time-of-Use (E-26) — legacy
On-peak 2–8 p.m. weekdays, May–Oct (closed to new enrollment)The classic 2–8 p.m. plan is closed to new sign-ups; existing households can stay on it until the November 2029 billing cycle. If you're still on it, your pre-cool deadline is 2 p.m. — the earliest and longest peak window in the Valley, and the reason SRP customers invented Phoenix supercooling culture in the first place.
Basic and M-Power
Flat prices · prepaid flat pricesSame price all day — no time pressure on the thermostat. If your household can't shift usage (home all evening, medical equipment, no smart thermostat), flat can honestly beat a badly-played time plan. The right answer is usage-dependent, and SRP lets you compare plans against your own history.
Supercooling: the SRP customer's home-field advantage
Every SRP time plan pays the same strategy: buy your cooling when it's cheap, coast when it's expensive. Pre-cool the house through the low-cost hours, let the thermostat ride up through the evening window, and the AC sits nearly idle during the only hours that hurt — on Conserve 6–9 p.m., mid-day energy costs about a sixth of evening peak in high summer.
How far to pre-cool, what your insulation has to hold, what it does to equipment runtime, and where the strategy honestly falls short — the full technique guide covers it.
