What Commercial Rebates Are Available Through AES Indiana in 2026?
AES Indiana offers prescriptive and custom rebates for qualifying commercial energy-efficiency projects.
Prescriptive rebates provide established incentive amounts for specific equipment and improvements. AES Indiana publishes applications covering HVAC and mechanical equipment, lighting and controls, commercial kitchen equipment, refrigeration, and vending controls.
Custom incentives provide a separate option for projects that generate measurable energy savings but do not fit the specifications of a prescriptive measure. Funding for these programs is limited and available on a first-come, first-served basis.
HVAC Rebates Lead the 2026 Incentive Opportunities
AES Indiana’s HVAC and mechanical equipment application covers central air-conditioning systems, heat pumps, HVAC controls, ventilation equipment, heat pump water heaters, and variable-frequency drives.
Several HVAC measures are also eligible for a temporary bonus, making this category especially important for businesses planning equipment replacements in 2026.
AES Indiana’s Limited-Time HVAC Rebate Offer
Through September 30, 2026, AES Indiana is offering a 15% bonus on qualifying HVAC rebates through its Midstream and Prescriptive programs.
The AES Indiana limited-time rebate offer applies to eligible:
- Air-source heat pumps
- Ductless heat pumps
- Water-source heat pumps
- Air-conditioning equipment
- Variable-frequency drives on compressors.
The bonus is added to the qualifying standard rebate. Equipment must still satisfy the program’s efficiency, capacity, installation, and documentation requirements.
Businesses considering an HVAC project should evaluate potential rebates before selecting or installing equipment. Waiting until installation is complete could make it difficult to correct equipment eligibility or documentation issues before the September deadline.
High-Value HVAC and Mechanical Rebates
AES Indiana highlights the following five HVAC measures as examples that may qualify for the limited-time bonus.
| HVAC or mechanical measure | Rebate Amount |
| Qualifying water-source or geothermal heat pump | $300 per 12,000 BTUh of cooling capacity |
| Variable-frequency drive on a compressor | $118.75 per controlled horsepower |
| Central air-conditioning system below 65,000 BTUh | $100 per 12,000 BTUh of cooling capacity |
| Air-source heat pump | $75 per 12,000 BTUh of cooling capacity |
| Ductless mini-split heat pump | $50 per 12,000 BTUh of cooling capacity |
These figures represent standard example incentives from the 2026 application. Qualifying projects may receive the additional 15% bonus through September 30, 2026.
HVAC Requirements That Can Affect Eligibility
AES Indiana determines HVAC eligibility based on equipment type, capacity, and efficiency. The program uses applicable ratings such as SEER2, HSPF2, EER, IEER, and COP to determine whether equipment meets program thresholds.
For split systems, the indoor coil and outdoor condenser generally must be a matched set. Eligible cooling systems may also need to operate for at least 1,500 hours annually.
Variable-frequency drives on compressors have separate conditions. A drive cannot replace an existing or failed VFD, and a second VFD compressor generally cannot be added to a system that already includes one. The compressor must be no more than 200 horsepower.

Product and Operating Rules for Lighting Projects
AES Indiana may require eligible lighting products to have ENERGY STAR certification or appear on the DesignLights Consortium Qualified Products List, depending on the measure.
Most lighting equipment must operate for at least 1,800 hours annually. LED-to-LED replacements do not qualify, and the new fixture’s wattage generally cannot exceed the existing fixture’s wattage. Completed projects must also provide appropriate light levels and comply with applicable electrical, safety, and energy codes.
Networked lighting controls have additional requirements. The system must appear on the DLC Networked Lighting Controls Qualified Products List and include capabilities such as individual fixture addressability, continuous dimming, scheduling, occupancy sensing, daylight harvesting, flexible zoning, and cybersecurity.
Commercial Kitchen Rebates Target High-Efficiency Equipment
AES Indiana offers rebates for qualifying commercial cooking, warewashing, and ice-making equipment. These incentives may benefit restaurants, schools, hospitals, hotels, grocery stores, and other facilities with commercial kitchens.
Five Notable Commercial Kitchen Incentives
AES Indiana includes the following five opportunities among the largest individual kitchen equipment rebates in its May 2026 application.
| Commercial kitchen equipment | Rebate Amount |
| Six-pan steam cooker | $2,500 per unit |
| Five-pan steam cooker | $2,000 per unit |
| Continuous ice machine producing 820–4,000 pounds per day | $1,875 per unit |
| High-temperature multi-tank conveyor dishwasher | $1,750 per unit |
| Four-pan steam cooker | $1,625 per unit |
Certification and Equipment Specifications
AES Indiana requires ENERGY STAR certification for kitchen equipment when specified in the application. The equipment must be new, and its make and model must match the invoice and manufacturer specification sheets submitted with the application.
Ice machine incentives depend on daily production capacity and whether the equipment uses a batch or continuous process. Dishwasher incentives vary depending on the machine configuration and operating temperature.
Refrigeration Rebates Cover Equipment and Efficiency Measures
AES Indiana commercial energy rebates include incentives for qualifying refrigerators, freezers, refrigeration controls, door equipment, and efficient motors.
Leading Refrigeration Rebate Examples
AES Indiana offers the following examples among its higher-value refrigeration rebates for qualifying commercial equipment and efficiency measures.
| Refrigeration measure | Rebate Amount |
| ENERGY STAR glass-door freezer larger than 50 cubic feet | $750 per unit |
| ENERGY STAR glass-door freezer from 30 to under 50 cubic feet | $531.25 per unit |

Vending Controls Offer Smaller, Targeted Rebates
Vending rebates support controls that reduce lighting or refrigeration energy use when equipment and surrounding areas are unoccupied. Because the application lists three vending measures, the table includes all available examples.
Available Vending Control Incentives
AES Indiana lists three prescriptive incentives for qualifying vending equipment controls.
| Vending control | Rebate Amount |
| Beverage reach-in controller | $43.75 per controller |
| Cold-drink vending equipment controller | $43.75 per controller |
| Snack machine motion controller | $25 per controller |
When Vending Controls Qualify
AES Indiana requires qualifying controls to be new additions to new or existing vending equipment. Replacing an existing control does not qualify.
Eligible systems must use passive infrared or dual sensing technology. Depending on the equipment, the control must switch off lights or reduce compressor operation when the surrounding area is unoccupied.
Custom Incentives Address Projects Outside Prescriptive Lists
AES Indiana custom incentives support energy-saving projects that do not fit a measure or specification in a prescriptive application. Potential projects may involve:
- Building automation systems
- Energy management systems
- Compressed-air improvements
- Process equipment
- HVAC systems
- Lighting systems
According to AES Indiana’s Custom Incentives fact sheet, eligible projects may earn up to $0.10 per kilowatt-hour saved above energy code. The projected first-year savings are determined through an energy model.
Custom incentives require preapproval, and the project must still be in the design phase. Businesses should not order equipment, begin installation, or make an irreversible project commitment before confirming program requirements.
Custom incentives are limited to 50% of total project costs and are subject to the program’s overall incentive caps.
Eligibility, Application Requirements, and 2026 Deadlines
Applicants must generally be active AES Indiana business customers with an eligible rate code at the time the equipment is installed. The 2026 applications list ISS, ISH, ISL, IPL, IPH, and IHL as qualifying rate codes.
New equipment must be more efficient than the existing equipment and satisfy the technical criteria established for the individual measure. Used, leased, rebuilt, rented, insurance-replacement, and warranty-replacement equipment generally does not qualify.
A complete prescriptive application typically requires:
- The AES Indiana account number and Service ID
- A completed and signed application
- An itemized invoice
- Manufacturer specification sheets
- Installing contractor information, when applicable
- The payee’s IRS Form W-9
- Any measure-specific supporting documents
Applications must generally be received within 90 calendar days of project installation or by December 31, 2026, whichever comes first. Equipment must be installed and operational by the applicable program deadline.
The limited-time 15% HVAC bonus has an earlier deadline of September 30, 2026.
Prescriptive rebates cannot exceed 50% of eligible material and external labor costs and are capped at $250,000 per project. Combined prescriptive and custom incentives are limited to $1 million per customer per calendar year. Funding is limited and available on a first-come, first-served basis.
