This comprehensive guide provides HVAC professionals with an in-depth technical overview of current energy rebate programs available in Arizona. Understanding these incentives is crucial for advising clients, optimizing project costs, and ensuring compliance with program requirements. This document details programs from Efficiency Arizona, Salt River Project (SRP), and Arizona Public Service (APS), focusing on eligibility, qualifying equipment, and application processes.
Efficiency Arizona: Household Energy Efficiency Rebates
Efficiency Arizona is a state-backed program designed to help qualified households improve energy efficiency through the installation of high-efficiency appliances and HVAC equipment. The program aims to enhance home comfort and reduce energy bills for Arizonans. Rebate availability and amounts are contingent upon eligibility criteria, primarily income level.
Qualified Products and Rebate Amounts
| Product Category | Maximum Rebate Amount |
|---|---|
| Heat Pump for Space Heating/Cooling | Up to $8,000 |
| Heat Pump Water Heater | Up to $1,750 |
| Insulation, Air Sealing, Ventilation | Up to $1,600 |
Note: All electrical services are only eligible with the installation of a qualified appliance. The rebate amount may not cover the full cost of the product; the applicant is responsible for the balance, taxes, and installation fees.
Application Pathways
- Contractor Pathway: This option is for applicants utilizing an Efficiency Arizona-qualified contractor for installations such as heat pumps, heat pump water heaters, insulation, air sealing, and electrical upgrades. The process involves homeowner application submission, eligibility determination by the Efficiency Arizona team, assessment scheduling, contractor assignment, agreement signing, homeowner payment to the contractor, work completion, and a post-inspection.
- Retail Pathway: This pathway is available for rebates on heat pump water heaters, heat pump dryers, and electric cooking appliances purchased through qualified rebate retailers. It involves applying online, application review, completing a retail interest form, receiving a coupon via email, and redeeming it at a participating retailer.
For detailed eligibility criteria and to apply, HVAC professionals should direct clients to the Efficiency Arizona website.
Salt River Project (SRP) Cool Cash™ Rebate Program
SRP offers the Cool Cash™ Rebate program to its residential electric customers for upgrading to energy-efficient air conditioning, heat pump, or mini-split systems. This program is designed to reduce energy consumption and provide financial incentives for high-efficiency HVAC installations.

- The applicant must be a permanent SRP residential electric customer residing in a single-family detached home, single-family attached home, mobile home, or apartment/condo.
- The qualified system must be installed by a contractor licensed in Arizona to install residential air-conditioning systems before April 30, 2026.
- The installation must replace or supplement an existing central heat pump or AC with a new high-efficiency system meeting minimum efficiency ratings.
- Manual J load calculations are required for single-stage systems. Failure to submit these can delay or deny the application. Load calculations are not required for multi-stage or variable-capacity systems.
- SRP or its agent may inspect the installed unit to verify compliance.
- Rebate applications must be submitted within six months of installation.
Note: New construction homes, window units, and installations in non-habitable spaces do not qualify. Both indoor air handler and condensing units must be replaced on split central systems.
Qualifying AC Units and Rebate Amounts
All qualifying equipment must be listed in the AHRI Verified Directories as meeting or exceeding the specified efficiency minimums (SEER2 15.2 or higher). Rebate amounts are per ton of cooling capacity:

Estimated Annual Savings
Upgrading to a higher SEER2 system can lead to significant energy savings. The following table provides estimated annual and 15-year savings based on compressor type and system size (assuming replacement of an existing 11 SEER system, $0.11/kWh, and 2,141 cooling hours):
| Compressor Type | Size (Tons) | 1-Year Savings Estimate | 15-Year Savings Estimate |
