Generator Installation FAQ for Honolulu Homeowners

How often should Honolulu homeowners get generator installation?
Given Honolulu's persistent trade winds carrying salt air corrosion throughout o'ahu, most homeowners benefit from generator installation at least once a year. Year-round salt air cleaning of metal fixtures, screens, and fasteners often makes spring or fall the optimal time to schedule service.
What home types in Honolulu most need generator installation?
Plantation-style homes with covered lanais (common throughout O'ahu) and Post-war concrete block homes in Honolulu proper are the most common home types in Honolulu and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How big of a generator do I need?
For whole-home coverage, 20–22kW handles most homes under 3,500 sq ft. Critical-circuit-only coverage can be achieved with 10–14kW. We calculate your exact load to right-size the unit.
How much does a whole-home generator cost?
Generac and comparable generators typically cost $5,000–$15,000 installed, including the unit, transfer switch, gas connections, electrical work, and permits. Larger homes or propane installs cost more.
Does a generator run on natural gas?
Yes. Standby generators connect to your existing natural gas line, so no fuel storage is needed. Propane is also an option for homes without gas service.
How long can a standby generator run?
Natural gas standby generators can run continuously for days or weeks as long as gas service is maintained. They're designed for extended outages, unlike portable units.
