SRP Cool Cash 2026: Do You Qualify, and What Will It Actually Pay?

Every year the rebate landscape shifts, and every year someone gets quoted a "rebate" that no longer exists. Here's where things stand for 2026. We handle the paperwork on every qualifying install, but you should know what's real going in.

Do you qualify? Six checks before you sign anything

Most of what gets a Cool Cash claim rejected is decided before the install, not after. Run your own situation against these first.

1. SRP or APS? This one decides everything. SRP customers have Cool Cash. APS customers get $0 on equipment as of January 1, 2026. Your utility is on the top of your bill, not determined by your city — Phoenix is split between both.
2. Is the whole system being replaced? A new outdoor unit on your existing indoor coil does not qualify. Both halves, AHRI-matched, or nothing.
3. Is it rated 15.2 SEER2 or higher? Below that the system is ineligible no matter what else is true.
4. Where is it going? A casita or a finished addition qualifies. A garage, workshop or other non-habitable space does not — this is the one that catches mini-split buyers.
5. Is it replacing something? New construction does not qualify. A failed unit and a working one you are upgrading both do.
6. Single-stage system? Then a Manual J load calculation has to go in with the application. Two-stage and variable-capacity do not require it. We run one on every install either way.

Hit a disqualifier? Two of these are fixable before the install and change what we would quote you — tell us which one you ran into. If you are on APS, skip to what is actually left for APS customers, because the rebate is not the lever any more.

Federal 25C tax credit — expired

The Energy Efficient Home Improvement Credit (25C) — the one that gave up to $2,000 back on a qualifying heat pump — ended for equipment placed in service after December 31, 2025. If a contractor is still advertising a "federal tax credit" on a 2026 install, ask them to show you the code section. There isn't one. Source: IRS guidance on P.L. 119-21.

APS — residential AC rebate discontinued

APS ended its residential AC and heat pump equipment rebate as of January 1, 2026 (Arizona Corporation Commission Decision No. 81584). What's left from APS is Cool Rewards — a smart thermostat program that pays a small credit for letting APS adjust your thermostat during peak events. It doesn't help with equipment cost.

If you're an APS customer (most of Ahwatukee, Scottsdale, and parts of Phoenix): plan on no utility rebate for a replacement. Manufacturer promotions and financing are the levers. Full detail: APS AC rebate 2026: what's left.

SRP — Cool Cash is still running

SRP customers (most of Tempe, Mesa, Chandler, Gilbert, and much of Phoenix) still have Cool Cash, a per-ton rebate on qualifying high-efficiency systems:

• $75 per ton — single-stage
• $150 per ton — two-stage / multi-stage
• $225 per ton — variable-capacity, and inverter-driven mini-splits

On a 4-ton variable-speed heat pump, that's $900 back. Requirements, as of this writing:

• AHRI-matched system rated 15.2 SEER2 or higher
• Installed by a participating contractor (we are)
• Manual J load calculation on file — required for single-stage systems, and we do one on every install regardless
• Application submitted within 6 months of install; program covers systems installed before April 30, 2027

Amounts and rules change. We confirm the current program the week we quote. Source: SRP Cool Cash.

How much SRP Cool Cash you'll actually get

Cool Cash is paid per ton of the new system's rated cooling capacity, by compressor type. Here's the check for the common sizes:

Columns: single-stage ($75/ton), two-stage or multi-stage ($150/ton), variable-capacity ($225/ton). Inverter-driven mini-splits also get $225/ton. A two-system home can claim each system, up to five per customer.

The jump from single-stage to variable-capacity is $450 to $750 more rebate on a typical house. That doesn't cover the full price difference between tiers, but it closes part of the gap, and the variable-speed system also saves the most on summer bills.

The fine print that trips people up

• It has to replace (or supplement) an existing central AC or heat pump. New construction doesn't qualify.
• Both halves of a split system have to be new. A new outdoor unit on the old indoor coil doesn't qualify. The system has to be AHRI-matched.
• Garages and other non-habitable spaces don't qualify. A mini-split in a garage gets no Cool Cash; one in a casita or addition can.
• Mobile homes, condos and townhomes do qualify, as long as you're a permanent SRP residential customer.
• Failed or working, either counts. You can replace a dead unit or upgrade a working one.
• Six months to file. Miss it and the rebate's gone. SRP can also ask to inspect the install.
• Single-stage needs a Manual J load calculation with the application. Two-stage and variable-capacity don't, but we do one on every install anyway.

Why we file it for you

The application wants the AHRI reference number, both model numbers, the coil and furnace numbers, compressor type, tonnage, the paid invoice and a signed contractor agreement. Most of that comes from the installer, so we submit it on every qualifying install and show the expected rebate as its own line on your quote. If SRP's program changes between quote and install, we tell you before we start.

Manufacturer rebates

American Standard's fall 2026 offer (we're an American Standard dealer): up to $900 instant rebate plus 0% APR for 60 months (on approved credit) on qualifying AccuComfort Platinum 20, Platinum 18, Platinum 19 Low Profile and Gold 17 systems paired with an eligible air handler or furnace and smart thermostat. Runs October 1 through November 15, 2026, and stacks with SRP Cool Cash. Source: American Standard.

On a 4-ton variable-speed system in SRP territory, that's up to $900 from American Standard plus $900 from Cool Cash.

Manufacturer promotions change by season. We apply whatever's active at the time of your quote and show it as a line item.

What this means for your decision

• SRP customer: high-efficiency variable-speed makes more sense than it did — the rebate scales with the efficiency tier.
• APS customer: the decision is pure math on bill savings vs. up-front cost. Variable-speed still wins over 10 years for most homes, but the payback is longer without the rebate.
• Anyone: don't let a rebate drive the sizing. A right-sized single-stage that fits the budget beats an oversized variable-speed installed to chase $900.
