Generator Installation for Hilo homes and businesses

Booking generator installation in Hilo should not take three quotes and two weeks of waiting. Standby and portable generator hookups with a proper transfer switch so nothing backfeeds. We assess, quote flat, and schedule around you.

If you are buying or selling in Hilo, an electrical inspection before the offer closes is far cheaper than a renegotiation after it. We document what we find and give you a written scope you can hand to anyone.

Hawaii Island spreads power across long rural feeders, vog-exposed coastline and homes above 2,000 feet that were often owner-built. Corroded lugs and undersized services are the two things we find most.

What Hilo customers say

★★★★★

Whole house surge protection after we lost a TV and a router in one storm. Cheap insurance, installed in an afternoon.

Andrew V., Hilo
★★★★★

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.

Generator Installation in Hilo: frequently asked questions

What size generator do I need in Hilo?
It depends what you want running. A critical loads setup covering fridge, lights, fans and a well pump is far cheaper than whole home coverage. We size it from a load calculation.
Do I need a transfer switch in Hilo?
Yes. Running a generator through an extension cord or a backfed dryer outlet can energise the utility line and is genuinely dangerous. A transfer switch isolates you properly.
Automatic or manual transfer in Hilo?
Automatic starts and switches on its own within seconds, which matters if you are away or have medical equipment. Manual costs less and is fine if someone is usually home.
How long does generator installation take in Hilo?
A manual interlock or inlet box is often a single day. A standby unit with an automatic transfer switch typically takes one to two days plus inspection.
Can you service a generator already installed in Hilo?
Yes, including transfer switch testing, load testing and fixing installs that were not done correctly the first time.
Where does the generator go on a Hilo property?
On a level pad, clear of windows and vents, with the manufacturer's clearances respected. We will walk the property and show you the options.
How fast can an electrician get to me in Hilo?
Most Hilo calls booked before early afternoon are handled the same day. True emergencies on Hawaii Island are dispatched as soon as a crew clears, day or night. Call (888) 633-7804 and you will get a real arrival window, not a vague promise.
What should I do while I wait for an emergency electrician in Hilo?
If you smell burning or see sparking, switch off the affected breaker or the main if you can reach it safely, unplug what is on that circuit, and stay clear. Then call (888) 633-7804 and describe what you saw so the right crew and parts are sent.
