Hawaiʻi Energy offers cool rebates for summer

Hawaiʻi residents have a cool way to get some money back for being energy efficient while staying cool during the summer through the state’s energy conservation program.

The Hawaiʻi Energy Residential Rebate Program is available through June 2025 to help lower energy bills when island residents invest in energy-efficient appliances and installations, including air conditioning equipment, whole house fans, pool pumps and more.

“We’re pleased to unveil Hawaiʻi Energy’s newest residential rebates that not only help residents save money, but also promote sustainable energy practices that benefit our environment,” said Hawaiʻi Energy Executive Director Caroline Carl. “Air conditioning alone can account for up to half of a household’s monthly energy consumption. This is a great opportunity for residents to make energy-efficient upgrades, save money and stay comfortable during the warm summer months.”

The rebate program offers a variety of incentives including:

Solar water heating: up to $1,500

Earn rebates for installing a new solar water heating system and maintenance, including:

• Solar Water Heater: $1,500
• Solar water heater tune up: $200

Heat pump: $500

Heat pump water heaters are twice as efficient as a conventional water heater, reducing water heating cost in half.

Cooling equipment: up to $1,000

Earn rebates for purchasing Energy Star or other efficiently-rated air conditioning systems, including:

• Central AC retrofit: $1,250
• Mini-split AC: up to $450
• Whole house fan: $100
• Solar attic fan: $75
• AC tune up: $75
• Window AC: $45

Refrigerator trade-up: $250

Earn $250 toward the purchase of a new Energy Star refrigerator when trading in an old, working model.

Pool pump: $150

Rebate given for the purchase and installation of a new Energy Star pool pump with a variable frequency drive.

“Rid-A-Fridge” recycling: $75

Earn cool cash just for getting rid of an old working refrigerator or freezer, no purchase necessary. Free haul-away and recycling included. Cannot be combined with trade-up offer.

To ensure all households can benefit from lower energy bills, Hawai‘i Energy also offers additional discounts on energy-efficient appliances and water heaters for eligible residents who identify as low income or in geographically remote areas.

Rebates are available to residential electric utility ratepayers on Hawaiʻi Island, Lāna‘i, Maui, Moloka‘i and O‘ahu only.

Kaua‘i residents are serviced by a utility cooperative and therefore not eligible for Hawai‘i Energy rebates.

The rebates are available on a first come, first serve basis and subject to availability of funds.
