If you’ve been thinking about upgrading your AC system or improving your home's energy performance, now is the time to act. Hawaii Energy’s limited-time rebate program ends June 30, 2025 — and it could save you hundreds of dollars on energy-efficient upgrades for your home or business.

💸 What Are the Rebates?
Through this program, Hawaii Energy is offering increased rebates on qualified energy-efficient equipment, including:
Mini-Split Air Conditioning System – Increased by $100 across all tiers, now offering up to $550 per unit.
Solar Water Heater System Installation – Increased by $500 to $2,000 per installation.
Heat Pump Water Heater Tune-Ups – Increased by $100 to $200 per maintenance service.
These rebates are available to residential electric utility ratepayers on Hawai‘i Island, Lanai, Maui, Molokai, and Oahu. They are offered on a first-come, first-served basis and are subject to fund availability.
Hawaii Energy encourages residents to take advantage of the increased incentives before the June 30 deadline.

⚠️ Why Act Now?
Deadline is June 30, 2025 — No extensions have been announced.
These rebates are some of the highest ever offered for mini-split ACs.
New federal refrigerant regulations and rising energy prices are making older systems more expensive to maintain and operate.
If you wait until July, you could miss out on hundreds in savings — and face longer wait times as demand spikes near the end of the program.
🧰 Is Your System Eligible?
Chances are good if:
Your AC system is 10+ years old
You're still using window units or an inefficient central system
You want to switch to zoned cooling with a quiet, ductless mini-split
✅ Bundle and Save Even More
When you combine your already energy-efficient upgrade with our Preventive Maintenance Plan, you not only extend the life of your new system — you can also get our remote monitoring service for just $15/month (regularly $30/month). It’s the smartest way to protect your investment long-term.
