Stay cool.
Without the AC bill.
Hawaii pays the highest electric rates in the country. We're the only QuietCool Platinum Dealer in Hawaii pairing whole house fans with solar attic fans as a single ventilation system — cutting A/C costs 50–90%, with rebate and tax credit help included.
At ~$0.43 per kWh on O‘ahu, every hour of A/C adds up fast.
A whole house fan uses roughly the energy of a couple of light bulbs. Run it instead of your A/C the hours you can — that's real money back on your bill, starting this month.

One Combined Ventilation System — Whole House Fan + Solar Attic Fan
Most Hawaii homes need two things working together: a way to pull cool air into the living space, and a way to pull built-up heat out of the attic. Island Cooling is the only QuietCool Platinum Dealer in Hawaii that offers both as a single, integrated system.
QuietCool Whole House Fan
Pulls cool outdoor air into your living space and flushes hot, stale indoor air out through the attic. A full-home air exchange happens every 2–3 minutes — at a fraction of the energy your A/C uses.
- Replaces or dramatically reduces A/C runtime
- Whisper-quiet — Stealth Pro is ~30 dB on low
- $100 Hawaii Energy rebate per qualifying whole house fan
- Works perfectly with Hawaii's open-window lifestyle
QuietCool Solar Attic Fan
Sun-powered ventilation that pulls trapped heat out of the attic before it can radiate down into your home. Runs on solar — no impact on your electric meter, day after day.
- Lowers attic temperatures by up to 40°F
- $75 Hawaii Energy rebate + state tax credit eligibility
- Pairs perfectly with whole house fans for whole-home performance
Why the combination matters: a whole house fan alone still has to fight the heat your attic radiates downward. A solar attic fan alone never moves the air inside your living space. Run together, the two cool every part of your home — and it costs you almost nothing to operate.
The Math Works in Your Favor
A QuietCool fan typically pays for itself in 1–3 years. After that, the savings keep coming for the life of the system.
50–90% off A/C costs
Run your fan in place of A/C during cooler hours and watch the kilowatt-hours drop. Most homes see the change on their very next bill.
1–3 year payback
Average return on investment for a QuietCool system in Hawaii. Every year after that is pure savings — for the life of the home.
Rebates & tax credits
We're the only active Hawaii dealer that helps you capture both Hawaii Energy rebates — $100 per whole house fan and $75 per solar attic fan — plus applicable state renewable-energy tax credits. We handle the paperwork as part of your project.
How a Whole House Fan Saves You Money
Three simple stages — no compressors, no refrigerants, no big bill.
Open Windows
Cool outdoor trade-wind air gets pulled inside through the windows you already have.
Circulate
A QuietCool fan moves a full home's worth of air every 2–3 minutes — silently.
Exhaust
Trapped hot attic air is pushed out through the roof vents instead of soaking back into your living space.
What We Offer
Three ways to cut your cooling costs — used together they stack.
Quieter than you remember.
Old whole house fans roared. The QuietCool Stealth Pro on low is ~30 dB — quieter than the inside of a library, and well below normal conversation. You hear the breeze, not the fan.

Common Questions
Straight answers about how the system works, what it costs, and how the rebates and tax credits stack up.
How does a whole house fan work?
A whole house fan is mounted in the ceiling between your living space and your attic. When you open windows and turn it on, it pulls cool outdoor air into the home and pushes hot indoor air up through the attic and out the roof vents. A typical Hawaii home gets a full air exchange every 2–3 minutes — for roughly the energy of a couple of light bulbs.
What's the difference between a whole house fan and a solar attic fan?
They solve two different problems. A whole house fan cools your living space by exchanging the air inside your home with cooler outdoor air. A solar attic fan cools your attic by pulling out the heat that builds up there during the day. Run together as one combined ventilation system — which Island Cooling is the only Hawaii dealer offering — they cool every part of your home for almost nothing in operating cost.
How much can a whole house fan save on my Hawaii electric bill?
Most homes see 50–90% lower A/C-related electric costs once the system is in place. Hawaii has the highest residential electricity rates in the country (~$0.43/kWh on O‘ahu as of May 2026), so the dollar savings here are larger than almost anywhere else in the U.S. The average return on investment for a QuietCool system in Hawaii is 1–3 years.
Are there rebates or tax credits for whole house fans and solar attic fans in Hawaii?
Yes — two from Hawaii Energy, plus state tax credits. Hawaii Energy currently offers a $100 rebate per qualifying whole house fan and a $75 rebate per qualifying solar attic fan. Solar attic fans may also qualify for state renewable-energy tax credits. Island Cooling is the only active Hawaii dealer that helps you capture all of these — we file the paperwork as part of your project.
Is QuietCool quiet enough for bedrooms?
Yes. The QuietCool Stealth Pro runs at roughly 30 dB on low — quieter than the inside of a library and well below normal conversation. Older attic fans you may remember from the 1980s ran 60+ dB; QuietCool's design is a different generation of technology entirely.
Do you serve every Hawaiian island?
Yes. Island Cooling has been serving every Hawaiian island since 2008 — from Hilo to Honolulu to Hanalei. We're the only QuietCool Platinum Dealer in Hawaii and have served over 8,000 Hawaii homes statewide.
