SRP Heat Pump Rebates for Phoenix Homes

Salt River Project (SRP) serves about a million customers across Phoenix Metro, with strong concentrations in Tempe, Mesa, Chandler, Gilbert, and parts of Paradise Valley. SRP’s residential efficiency rebates have shifted in recent years to favor electrification, and the heat pump rebate is now the headline incentive at $225 per ton for qualifying systems plus an additional cooling rebate when the SEER2 tier is met.

For a typical 4-ton Phoenix replacement, that’s $900 from SRP alone, before stacking the federal 25C credit and HEEHRA. This article walks through what SRP pays in 2026, the eligibility checklist, and how to layer state and federal incentives on top.

SRP’s 2026 heat pump and cooling rebate structure

SRP’s 2026 program splits residential HVAC rebates into two parallel tracks: equipment rebates (paid after install) and demand response enrollments (paid as ongoing bill credits).

On the equipment side, the heat pump rebate is $225 per ton for systems meeting SEER2 16 / HSPF2 8.1 minimums, with bonus tiers for higher efficiency. A 3-ton qualifying system earns $675; a 4-ton earns $900; a 5-ton earns $1,125. Variable-speed inverter heat pumps from Carrier, Trane, Lennox, Mitsubishi, and Daikin frequently qualify for the bonus tier, which can push per-ton amounts to $300+ depending on the program window.

For homeowners who choose a high-efficiency AC instead of a heat pump (because they already have a working gas furnace and aren’t ready to electrify), SRP runs a separate cooling rebate at $200 to $400 per system depending on SEER2 rating. SRP also offers smart thermostat rebates ($50 to $100) for ENERGY STAR thermostats enrolled in the SRP Bring Your Own Thermostat (BYOT) demand response program.

Stacking SRP with HEEHRA and the federal 25C credit

The big numbers come from stacking. A heat pump install in Mesa or Gilbert (both SRP territory for most addresses) can layer four incentives.

First, the SRP equipment rebate at $225 to $300+ per ton. Second, the federal Inflation Reduction Act 25C tax credit, which pays 30% of qualifying heat pump costs up to a $2,000 cap per year for any taxpayer (no income limit). Third, the HEEHRA rebate for income-eligible households: up to 100% of the install for households at or below 80% of area median income, and up to 50% for households at 80% to 150% AMI. For a 4-person household in Maricopa County, 80% AMI is around $80,000 in 2026. Fourth, sometimes a manufacturer rebate or contractor seasonal promotion in the $300 to $1,500 range.

Real numbers for a 4-ton variable-speed Carrier or Trane heat pump in Tempe at $16,500 installed: SRP rebate $900 to $1,200, federal 25C credit $2,000, manufacturer rebate $500, net out of pocket $12,400 to $13,100. For a HEEHRA-qualifying household, the federal rebate can cover an additional $4,000 to $8,000, sometimes bringing net out of pocket under $5,000 for a fully variable-speed system.

Eligibility rules that catch homeowners

SRP rebates are for residential customers with active service inside SRP territory installing equipment in their primary or secondary residence. Renters need the property owner to apply.

Three rules trip up applicants regularly. First, the contractor has to be an SRP Trade Ally (the SRP equivalent of a Qualified Contractor). The Trade Ally list is at savewithsrpbiz.com (or via the Cool Cash portal) and is updated monthly. Second, the equipment AHRI certificate has to be submitted with the application, and the AHRI number on the certificate has to match the model and serial on the invoice. Third, the installation date has to fall within the active program year window, and applications must be submitted within 60 days of install (sometimes 90, check the current rules).

A common denial: homeowner installed a system in late December that the contractor didn’t submit until February of the new program year. The new program year had different tier amounts, the rebate dropped by $300, and the homeowner had to eat the difference. Confirming submission timing in writing avoids this.

Why heat pumps make sense in Phoenix in 2026

Phoenix used to be a “AC + gas furnace” market because winter heating loads are minimal and gas was cheap. Three things have shifted that calculus.

First, the federal R-454B refrigerant transition that took effect in 2025 has compressed equipment options and pricing. New AC-only systems and new heat pumps are now sold side by side at similar price points, which makes the heat pump’s secondary benefit (heating without a separate furnace) close to free. Second, modern variable-speed heat pumps maintain rated capacity down to 17 degrees F, well below any winter low Phoenix sees, so the historical “heat pumps don’t work in cold” objection is gone. Third, SRP and APS rebates plus federal incentives now favor heat pumps over cooling-only replacements by $500 to $1,500.

The cases where a traditional AC installation plus furnace combo still wins: homes with very recent (under 5 years old) gas furnaces in good condition, homes outside utility rebate territory, and homes with constrained electrical service where an electrical panel upgrade would push the heat pump project past budget. In every other case, the heat pump math wins in 2026.

Common questions about SRP rebates

Can I apply for the SRP rebate myself?

The application is filed by the contractor under most program tracks, with the homeowner co-signing the W-9. A few smaller rebates (smart thermostat enrollments, audit-based incentives) can be filed homeowner-direct through the SRP customer portal. Always confirm with the contractor before assuming who files.

What if I’m in SRP territory but my contractor only works with APS?

Contractors generally hold both SRP Trade Ally and APS Qualified Contractor status because Phoenix Metro is split between the two utilities. If your chosen contractor is APS-only, ask whether they can complete SRP Trade Ally onboarding before your install (it takes 2 to 4 weeks). Otherwise, swap to a contractor who’s already in both networks.

How is the $225 per ton calculated?

By the equipment’s nominal cooling tonnage on the AHRI certificate, not the home’s actual heat load. A 3.5-ton system pays $787.50 (3.5 x $225). Tier bonuses for variable-speed inverter systems can raise the per-ton amount to $275 to $325 depending on the program window.
