What customers across Hawaii say

★★★★★

Called at 11pm with a burning smell in the hallway. Someone answered, someone showed up, and I slept that night. Hard to overstate how much that was worth.

Dave R.
★★★★★

Sparking outlet in the kitchen on a Sunday. Answered, quoted, fixed. No weekend runaround.

Curtis M.
★★★★★

Half the house went dark on a holiday weekend. They picked up, came out, found a failed main lug.

Frequently asked questions

How do I know my Hawaii panel needs upgrading?
Full breaker slots, double-tapped breakers, a fuse box, frequent tripping, a warm cover, scorch marks, or a plan to add an EV charger, AC or a range. Any one of those is a reason to look.
How long does a panel upgrade take in Hawaii?
Most residential upgrades are a one day job, with power off for part of it. Utility coordination and inspection can add scheduling time, and we handle that for you.
What size service should I get in Hawaii?
200 amp is standard for most homes now, especially with an EV or a heat pump in the plan. We run a load calculation rather than guessing.
Can you replace just the breaker box in Hawaii?
Sometimes, if the service and meter are in good condition. If the service entrance cable is undersized or corroded, replacing only the box leaves the real bottleneck in place.
Do I need a permit for a panel upgrade in Hawaii?
Service work is permitted and inspected. We take care of the paperwork and the inspection appointment as part of the job.
Will my power be off all day in Hawaii?
Not usually all day. We plan the outage window with you in advance so you can move anything temperature sensitive first.
