Plan your purchase
A new air conditioner is a big purchase. Here is how Oahu homeowners bring the cost down: Hawaii Energy rebates, a written quote you can compare line by line, and phasing the work one zone at a time. If you need to spread out payments, ask when you request your quote.
Hawaii Energy Instant Rebate Per Split AC Outdoor Unit
Hawaii Energy instant rebates on qualifying high-efficiency split AC systems installed by a Clean Energy Ally contractor. Counted per outdoor unit, so separate single-zone systems can each earn one.
Code: REBATE550
Ask for a written quote that lists the equipment, the labor, any permits and any Hawaii Energy rebate line by line, so you can compare it with other bids. See typical Oahu installed ranges in our AC cost guide or answer a few questions in the instant estimate.
Hawaii Energy pays $400 to $550 per qualifying split AC or mini-split outdoor unit, set by size and SEER2 rating. A 9,000 or 12,000 BTU unit earns $450 if it is rated 17.2 SEER2 or better. The program also pays $1,250 for a qualifying central AC retrofit and $75 per qualifying AC tune-up, subject to program availability through June 30, 2027. Except for ENERGY STAR window units, the work must be done by a Hawaii Energy Clean Energy Ally contractor. See Hawaii Energy rebates for the full tier table.
Ductless split systems can be added one room at a time. You can start with the bedrooms or the hottest room and add zones later, which spreads the spending over more than one budget cycle. Rebates are counted per outdoor unit, so separate single-zone systems can each earn their own rebate, while one multi-zone system earns one.
Oahu residential electricity costs about 43¢ per kWh, roughly 2.3 times the U.S. average, so a high-efficiency system can noticeably lower your monthly bill. Our guide to lowering your AC electric bill shows where the savings come from.
