Which Arizona HVAC Rebates Are Available in 2026?
Arizona homeowners can still apply for qualifying Efficiency Arizona HVAC rebates under revised rules, but the former gas-to-electric reservation deadline has passed. New HVAC equipment placed in service in 2026 does not qualify for the federal Section 25C tax credit. Tucson Electric Power offers separate equipment rebates to eligible residential customers using participating contractors.
For Tucson homeowners comparing HVAC replacement options with Temco AC, the first step is to identify the rebate program, existing equipment and approval requirements that apply to the proposed work. A rebate reduces an eligible project cost; a tax credit reduces qualifying tax liability. Neither is an automatic discount on every new system.
| Program | Status for a new project | Main eligibility condition |
|---|---|---|
| Efficiency Arizona | Applications accepted under revised rules | Income, equipment, property and approval requirements apply. |
| TEP Efficient Home Program | Qualifying HVAC rebates listed | TEP customer eligibility and participating-contractor installation required. |
| Other Arizona utility programs | Provider-specific offers | Use the program for the electricity provider serving the home. |
| Federal Section 25C | Unavailable for equipment placed in service after December 31, 2025 | A qualifying 2025 installation may still support a 2025 tax claim. |

Efficiency Arizona Rebates Support Eligible HVAC Upgrades
Efficiency Arizona is a state-administered rebate program for eligible households. Its published household ceiling is $14,000 across eligible measures, subject to individual limits, income qualification and funding availability. That ceiling is not a $14,000 rebate for one heat pump.
Efficiency Arizona also publishes up to $1,750 for an eligible heat pump water heater and up to $1,600 for eligible insulation, air sealing and ventilation combined, subject to income, equipment and project approval requirements. Efficiency Arizona rebates of up to $4,000 for an electric panel and $2,500 for wiring must accompany an eligible appliance installation. Household and individual measure limits apply together.

Efficiency Arizona’s Former Rebate Deadlines Have Passed
Efficiency Arizona changed its rules for rebate reservations from September 1, 2026. The following dates concern access to the former guidelines, not the closure of the entire program.
| Date | Former-rule milestone | What the date means now |
|---|---|---|
| August 1, 2026 | Recommended application date | Allowed processing time for gas-to-electric projects under the former rules. Applying did not itself secure a reservation. |
| August 28, 2026 | Final reservation deadline | An approved application, any required assessment and approved contractor scope were needed to reserve under the former rules. |
| September 1, 2026 | Revised rules took effect | Reservations made on or after this date follow the new guidelines. |
A project with a qualifying reservation secured under the former rules can have installation, redemption and payment occur after August. Homeowners with an existing reservation should confirm its specific terms and completion requirements with the program administrator. New applicants cannot use the expired reservation pathway.

Household Income Determines Arizona Heat Pump Rebate Coverage
Efficiency Arizona uses area median income, or AMI, to determine income eligibility. AMI limits depend on county or area and household size. The program uses gross household income before taxes and deductions, and approved assistance-program participation may provide a categorical qualification route.
| Household income tier | Efficiency Arizona heat pump coverage |
|---|---|
| Below 80% of AMI | Up to 100% of eligible product cost, capped at $8,000, subject to program approval. |
| 80% through 150% of AMI | Up to 50% of eligible product cost, capped at $8,000, subject to program approval. |
| Above 150% of AMI | Not eligible under the program’s published income limits. |
The $8,000 cap does not mean every approved household receives $8,000 or a free installation. Ask for a written quote showing the approved rebate, covered costs and remaining balance, including any costs outside rebate coverage. Use the official screening tool and current income limits; screening is not final approval.

Adding a Heat Pump Differs From Replacing Gas Heating
Efficiency Arizona’s revised rules do not rebate replacing or removing a fossil-fuel heating appliance in favor of an electric heat pump. The program FAQ permits an eligible heat pump to be added alongside a fossil-fuel appliance when the fossil-fuel heat source remains in place; other program requirements still apply.
Qualifying electric HVAC upgrades can include replacing an electric furnace, electric baseboard heating or a less efficient heat pump. The new heat pump must meet the program’s ENERGY STAR requirements. Insulation or air sealing may also be required alongside a rebated heat pump project. A contractor must evaluate the actual equipment configuration before eligibility is assumed.

Efficiency Arizona Requires Approval Before Installation
Efficiency Arizona does not rebate completed HVAC projects. For the contractor pathway, apply and obtain the required program approval before installation; the rebated work must use an Efficiency Arizona Qualified Contractor.
- Check household and property eligibility using the official program tools.
- Submit the application with current required income, property and household documentation.
- Complete the eligibility review, assessment if required, and contractor scope review; confirm the rebate reservation before work starts.
- Review the contractor agreement and the written balance you will owe after the approved rebate.
- Have the qualified contractor complete the approved work and required verification. The rebate is applied to eligible contractor invoice costs.
The retail coupon pathway covers specified appliances such as heat pump water heaters, dryers and cooking equipment, rather than space-conditioning heat pumps. Retail coupons require approval before purchase and must be redeemed through a participating retailer; they cannot be applied retrospectively.

TEP Offers HVAC Rebates to Eligible Tucson Customers
TEP’s Efficient Home Program lists the following maximum rebates for qualifying residential work. Equipment installation rebates require a participating program contractor, and the applicable rebate is deducted from the project price. Confirm contractor participation and the specific amount before work begins.
| Qualifying work through a participating TEP contractor | TEP maximum subject to eligibility |
|---|---|
| High-efficiency heat pump quality installation | Up to $720 |
| High-efficiency air conditioner quality installation | Up to $600 |
| Mini-split heat pump or air conditioner | Up to $100 per ton |
| Duct sealing | Up to $300; depends on leakage reduced |
| Eligible A/C tune-up work | Up to $160 across qualifying charge repair and coil cleaning measures |
TEP also lists a $35 rebate for a new qualifying smart thermostat purchased and installed during its 2024–2026 program period, a $400 account credit for an eligible ENERGY STAR heat pump water heater, and up to $800 for eligible attic or roof insulation installed through a licensed insulation contractor. These are separate incentives with their own customer, model and installation rules.

Arizona Utility HVAC Rebates Depend on Your Electricity Provider
Utility rebates follow the home’s electricity service account. An SRP offer does not become available to a TEP customer simply because both homes are in Arizona. Check the provider shown on the electric bill and its current residential program.
| Electricity provider | Published HVAC offer | Key program condition |
|---|---|---|
| SRP | Cool Cash per ton: single-stage $75; multi-stage $150; variable-capacity and qualifying inverter mini-splits $225. | Minimum 15.2 SEER2 and listed qualifying equipment. Installation before April 30, 2027; submit within six months of installation. |
| UniSource | Up to $450 for qualifying heat pump quality installation; up to $375 for qualifying A/C quality installation. | Eligible work must use a participating Efficient Home Program contractor. |
SRP also requires an Arizona-licensed installer and applicable documentation, including Manual J calculations for single-stage systems. For APS, a cooperative or another provider, consult that provider’s current offers instead of relying on an old statewide rebate list. Utility participation does not replace Efficiency Arizona approval.

The Federal 25C HVAC Tax Credit Ended After 2025
The federal Energy Efficient Home Improvement Credit under Section 25C is unavailable for HVAC equipment placed in service after December 31, 2025. Buying equipment before that deadline did not make a later 2026 installation eligible. The former credits below are historical limits, not current rebates for new purchases.
| Historical equipment category | Former maximum for qualifying 2025 installations |
|---|---|
| Central air conditioning | Up to $600 per qualifying item |
| Qualifying heat pumps and heat pump water heaters | Up to $2,000 annually within the applicable category limit |
| Qualifying furnaces, boilers and supporting electrical components | Up to $600 per qualifying item, subject to category and annual limits |

Qualifying 2025 HVAC Installations May Support a Tax Claim
A homeowner with qualifying equipment placed in service in 2025 may claim the applicable credit for the 2025 tax year using Form 5695, subject to IRS requirements. Eligibility includes the applicable equipment efficiency standards and, for specified property, the required qualified manufacturer identification number. The credit is nonrefundable and unused credit cannot be carried forward.
Retain the dated invoice, installation records and manufacturer documentation. Some rebates and subsidies reduce the expenses used to calculate a historical tax credit; ask a tax professional about an unclaimed qualifying 2025 installation or an amended return.

Can Arizona Homeowners Combine HVAC Rebates?
Efficiency Arizona permits rebates and discounts to be combined when the other programs allow it, but total rebates and discounts must not exceed the project cost. Income eligibility for a state rebate does not automatically establish utility eligibility or determine the final combined amount.
Ask the program administrator and participating contractor to confirm each incentive in writing, including which costs are eligible and how each discount affects the remaining balance. Do not include a Section 25C credit in the savings estimate for equipment installed in 2026.

Check HVAC Rebate Eligibility Before Installation
Before authorizing an Arizona HVAC installation, verify the following details for the actual home and proposed equipment:
- Identify the electricity provider and the specific rebate programs you intend to use.
- Confirm household, property and existing-equipment eligibility under the rules in effect for the reservation.
- Check the proposed model, efficiency rating and required installation or weatherization work.
- Verify the contractor’s participation in each applicable program.
- Obtain required approval or reservation before work and record any installation or submission deadline.
- Keep a written quote that separates equipment, labor, approved incentives and your remaining balance.
