Hawaii Energy AC Rebates for July 2026 to June 2027: What Qualifies and How They're Paid

Hawaii Energy's 2026–27 rebate program runs through June 30, 2027, or until the money runs out. The headline amounts are easy to find: $400 to $550 per split AC outdoor unit ($450 for the 9,000 and 12,000 BTU units in most bedrooms), $1,250 for a central retrofit and $75 for a tune-up. The details that decide whether you actually get the money are harder to pin down.

At Universal Air Hawaii, the rebate is its own line on every quote we write, so we checked the fine print against Hawaii Energy's own applications and contractor guidelines. This guide covers which split systems qualify, why the rebate shows up on your invoice and never in your mailbox, what you'll need from your electric bill, and how the central AC, tune-up and business rebates work.

01What's on offer this program year

Hawaii Energy announced its 2026–27 rebates in July. These are the cooling rebates most Oahu homes and businesses will care about, with the conditions taken from the program's contractor guidelines and applications:

There are also smaller rebates for whole-house fans ($100) and solar attic fans ($75).

02The split AC tiers, and why a bedroom unit can miss out

Split AC rebates are set by the outdoor unit's cooling capacity and its SEER2 efficiency rating. These are the tiers on the 2026–27 application:

Look at where the 15.3 SEER2 tier starts. It begins at 14,000 BTU, which means the 9,000 and 12,000 BTU units that go into most Oahu bedrooms need a rating of 17.2 or higher to earn anything. A budget 12,000 BTU unit at 16 SEER2 gets no rebate at all.

The rating has to be verifiable in the AHRI Directory, which lists certified efficiency for matched indoor and outdoor combinations. Ask your contractor for the AHRI reference number before you commit, especially if the equipment is close to a tier cutoff.

The application asks for the model and serial number of each outdoor unit, and the capacity tiers apply to each one. So a home with three single-zone systems can claim three rebates. A multi-zone system that runs three rooms off one outdoor unit gets one.

03How the instant rebate is paid

You won't get a check. Under the application's terms, Hawaii Energy pays the rebate to the contractor, and the contractor applies it to your invoice. The process runs like this:

1. Your contractor confirms the equipment meets the capacity and SEER2 requirements before you buy.
2. You provide the Electric Contract ID from the top right corner of your Hawaiian Electric bill, along with the name on the account.
3. The invoice lists the rebate, plus the brand, model and serial number of each outdoor unit and the cost per unit.
4. You sign the application to confirm you received the instant rebate, and the contractor sends it with the invoice to Hawaii Energy within 30 days of purchase.
5. Hawaii Energy may inspect the installation at any point up to five years after paying.

If someone tells you a split AC rebate check is coming in the mail, that isn't how this program pays out.

04Who qualifies

The residential rebates are for account holders on Oahu, Maui, Hawaii Island, Molokai and Lanai whose electric bills pay into the Public Benefits Fund. Kauai isn't covered.

Newly constructed homes don't qualify. Homes you've recently bought do. Renters can apply too, as long as the landlord signs the waiver on the back of the application.

Funding is first-come, first-served, and Hawaii Energy can change terms or end a rebate early if the money runs out. Don't count on it still being there in June.

05Central AC retrofit: get preapproval first

The $1,250 rebate is for replacing an existing central system with a more efficient one. The old outdoor unit must be rated 13.0 SEER or lower, and the new indoor and outdoor units must both be 15.2 SEER2 or better. The invoice has to show both units.

Hawaii Energy also requires preapproval before the work is done. Skipping that step is the easiest way to lose this rebate, so make sure your contractor submits for it before scheduling the install. Our central AC page covers retrofits, and the best AC for Hawaii can help if you're unsure whether to keep the ducts at all.

06The $75 tune-up rebate

The tune-up application covers central and split systems, not window units. You can claim one per condenser per year, up to two per location, and only if the system hasn't been tuned in the past year. A Clean Energy Ally has to do the work.

The application also shows what Hawaii Energy expects a tune-up to include. The technician records refrigerant pressures and supply air temperature before and after, cleans the outdoor and indoor coils, checks drains and pans for biological growth, tightens wiring connections and confirms the fans turn freely. A quick filter rinse and a look around wouldn't pass that checklist, which makes it a useful yardstick when you're comparing maintenance offers. Our mini-split cleaning guide covers how often Oahu systems need it.

07Businesses, condos and AOAOs

Commercial accounts can get up to $275 per ton for package or split AC and for VRF systems. Hawaii Energy's business HVAC page says packaged and split units must be at least 10% more efficient than the current energy code, and its eligibility worksheet lists the requirements by equipment type. A 20-ton system at the full rate would come to $5,500.

Condo owners who pay their own Hawaiian Electric bill apply as residential customers for equipment in their unit. Building-wide equipment on the association's account goes through the business side, and Hawaii Energy has a page for multifamily and AOAO properties. If you're adding AC to a condo, our AOAO approval guide covers the board's side of things.

08eHale is a separate program

Hawaii Energy rebates are available now. eHale, the state's version of the federal heat pump rebates, is run by a different agency, hasn't opened yet and has its own income rules. Our eHale guide explains who it's likely to help and whether it's worth waiting for.

09Getting the rebate on your install

Every quote we write lists the Hawaii Energy rebate as its own line, so you can see the price before and after. If you're close to a tier cutoff, we can price two models side by side to show what the higher-efficiency unit really costs once the rebate comes off.
