What Mililani customers 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., Mililani
★★★★★

Tesla Wall Connector install. Clean conduit run, nothing sloppy, and they did a load calc first instead of just hoping it would hold.

Electrical Panel Upgrade in Mililani: frequently asked questions

How do I know my Mililani 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 Mililani?
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 Mililani?
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 Mililani?
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 Mililani?
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 Mililani?
Not usually all day. We plan the outage window with you in advance so you can move anything temperature sensitive first.
Can you upgrade my panel and add an EV charger at the same time in Mililani?
That is usually the cheapest way to do it. One mobilisation, one load calculation, one inspection. We size the service for the charger plus anything else you are planning, such as a mini split or induction range.
My breaker keeps tripping in Mililani. Is that an emergency?
A breaker that trips occasionally under heavy load is a capacity problem. A breaker that trips immediately every time you reset it is a fault, and that one needs attention now. If there is heat, buzzing or a burning smell, call (888) 633-7804 straight away.
