APS HVAC Rebates in 2026 Explained

Arizona Public Service (APS) serves about 1.4 million customers across 11 counties, including most of east and west Phoenix, Glendale, Peoria, Surprise, Goodyear, and parts of Scottsdale. The utility’s residential efficiency rebates change every program year, and 2026 brings a few notable shifts: higher base amounts for variable-speed heat pumps, a tightened SEER2 floor, and a streamlined contractor-handled application process for most equipment categories.

This article walks through what APS will pay in 2026, the eligibility rules that catch homeowners off guard, and how to verify your contractor is on the qualified list before you sign a proposal.

What APS pays in 2026

APS organizes residential HVAC rebates into three main equipment buckets: high-efficiency air conditioners, heat pumps, and smart thermostats. Amounts shown below reflect APS published guidance for the 2026 program year. Always confirm at aps.com/rebates before signing because tiers and budgets adjust mid-year.

For central air conditioners, APS pays roughly $300 to $500 for SEER2 16+ split systems and $500 to $800 for SEER2 18+ variable-speed systems. Heat pumps qualify at higher amounts: roughly $400 to $600 at SEER2 16 / HSPF2 8.1 and up to $1,200 to $1,500 for variable-speed inverter systems with HSPF2 9.0 or better. ECM-blower-equipped systems and units paired with a qualifying duct sealing scope can stack additional incentives.

Smart thermostat rebates run $30 to $75 for ENERGY STAR-certified models like the Ecobee Premium, Nest Learning, or Honeywell T9. The thermostat must be enrolled in APS Cool Rewards, which lets the utility do brief setpoint adjustments during peak events in exchange for a bill credit. A homeowner can opt out of any individual event from the thermostat or app.

Who qualifies and what trips up applicants

APS rebates are for residential customers with active service on a qualifying rate plan, installing equipment in their primary or secondary residence within APS service territory. Rentals qualify if the property owner submits the rebate.

The catches: equipment must be installed by an APS Qualified Contractor (QC), the install date and invoice must align with the program year window, and the equipment AHRI certificate has to be submitted alongside the application. A surprising number of denials come from homeowners who pulled a permit themselves, used a non-QC contractor, or installed equipment that meets the manufacturer’s SEER spec but not SEER2 (the post-2023 testing standard). Always confirm SEER2 numbers, not legacy SEER.

Income-eligible households can stack APS rebates with the federal HEEHRA (Home Electrification and Appliance Rebate Act) program, which can cover up to 100% of a heat pump 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 runs roughly $80,000 in 2026. A licensed contractor handling heat pump installation can confirm whether your project is HEEHRA-eligible during the proposal stage.

How a real install looks with the rebate stacked

A homeowner in Glendale replacing a 14-year-old 4-ton AC and gas furnace with a Carrier Infinity variable-speed heat pump (SEER2 19, HSPF2 9.5) might see numbers like this in 2026.

Equipment + install: $14,500 to $17,500 depending on duct work, electrical service upgrades, and refrigerant line modifications for the R-454B transition. APS rebate for the heat pump tier: $1,200 to $1,500. Smart thermostat rebate (Ecobee Premium enrolled in Cool Rewards): $50 to $75. Federal Inflation Reduction Act 25C tax credit for heat pumps: 30% of qualifying costs up to $2,000. Net out of pocket lands in the $11,000 to $13,500 range, with monthly bill savings of $40 to $90 depending on prior usage.

If the same household qualifies for HEEHRA, the federal rebate can cover an additional $4,000 to $8,000 for income-qualified buyers, sometimes pushing net out of pocket below $5,000 for a fully variable-speed system. Stacking is allowed but requires careful documentation, and your contractor’s role in submitting the right forms in the right order matters. A good AC installation quote walks through the rebate stack line by line.

Making sure your contractor handles the paperwork right

The biggest source of unpaid rebates in the Valley is paperwork: missing AHRI certificates, missing model and serial numbers on the invoice, install dates that fall outside the program window, or applications submitted under the wrong rate plan. A qualified APS contractor handles this routinely and includes the rebate paperwork in the install package.

Before signing a proposal, ask the contractor to confirm three things in writing. First, that they’re an APS Qualified Contractor for the equipment category you’re buying. Second, that the equipment model carries SEER2 (not legacy SEER) certification at or above the rebate tier. Third, that they will submit the application on your behalf and provide copies of the submission and approval emails.

If your home also needs a smart thermostat upgrade, APS pays a separate rebate for ENERGY STAR thermostats enrolled in Cool Rewards. A licensed pro can handle thermostat installation at the same time as the AC or heat pump install for around $250 to $450 in labor, often net-zero after the rebate.

What changes if you’re outside APS territory

Roughly half of Phoenix Metro is served by SRP, not APS. Households in Tempe, Mesa, parts of Chandler, parts of Gilbert, and Paradise Valley are typically SRP customers, while west Phoenix, Glendale, Peoria, Goodyear, Surprise, and Avondale are typically APS. There’s no overlap; you have one utility per address. Check your bill or the utility lookup at srpnet.com or aps.com.

SRP runs a parallel but distinct rebate program with different tier amounts (currently $225 per ton for qualifying heat pumps, plus a separate cooling rebate for high-efficiency ACs). If you’re an SRP customer, the contractor selection and paperwork rules are similar but the application portal and qualified contractor list are separate. Federal HEEHRA and 25C credits work the same way regardless of utility.

Common questions about APS rebates

Can I apply for the rebate myself if my contractor isn’t an APS QC?

No. APS rebates are restricted to equipment installed by Qualified Contractors. The QC list is at aps.com and is updated monthly. Hiring a non-QC contractor disqualifies the install regardless of the equipment’s efficiency rating.

How long does the rebate take to arrive?

APS publishes a 6 to 8 week processing window from application submission to check. If the application is complete and the equipment matches a tier, most homeowners see the rebate within that window. Delays usually trace to missing AHRI certificates or invoice discrepancies.

Does the rebate apply to repairs or only replacements?

Replacements only. APS rebates are for new equipment installs that improve efficiency over existing equipment. Repair scopes (capacitor swaps, refrigerant top-offs, control board replacements) don’t qualify. If your existing system is at end of life, the contractor can include a written assessment with a replacement quote.
