Installer landscape

Hawaii (Pacific islands) is a propane or electric first standby market. Utility gas heats only 3.7% of homes (ACS 2024). Expect propane tank sizing and refill logistics, or an electric-first conversation, more often than a simple gas tap. In 2024, Hawaii electricity customers averaged 5.3 hours without power (near the 10.2-hour U.S. average; EIA Electric Power Annual Table 11.3). Dominant drivers in this research pass: island grid, wind, volcanic. This directory lists 24 researched installers with website generator signal (13 with a dedicated generator page, 2 with repeated signal, 9 with at least one clear mention). That is a very thin market by national listing volume, ranking #50 of 50. Top city clusters in the directory: Honolulu (7), Hilo (3), Kailua-Kona (2), Princeville (2).

Fuel, codes, and cost context

Budget for propane tank, pad, and refill logistics in addition to the electrical package; gas-line savings rarely apply. NEC edition in effect in this research pass (verified as of August 2026): 2020. We do not publish fabricated statewide average install prices.

Before you call

Hawaii has almost no utility-gas heating (3.7%). Island logistics, limited installer density, and electric-dominant housing change both fuel and lead-time conversations versus mainland gas markets. Use the 24 researched listings below as a starting point, not an endorsement. Verify licensing, insurance, references, and recent standby work yourself.

Fuel and outage figures sourced from ACS 2024 and EIA 2024; NEC and licensing notes verified as of 2026-08-07. Not legal advice. Confirm with your AHJ.
