What Hawaii Residents Should Know
Hawaii falls in IECC climate zone 1A with 0 heating degree days per year — well below the national average. With an average heating COP of 3.8, heat pumps in Hawaii operate at high efficiency, producing 3.8 units of heat for every unit of electricity consumed.
With natural gas at $3.50 per therm in Hawaii, a gas furnace may have lower operating costs in the coldest months. However, heat pumps provide both heating and cooling in one system, which can offset the difference when you factor in AC savings. In shoulder seasons (spring and fall), a heat pump is significantly more efficient, often making the overall annual cost competitive with gas.
While Hawaii does not currently offer state-level heat pump incentives, the federal 25C energy efficient home improvement tax credit covers up to $2,000 for qualifying heat pump systems. This credit, combined with long-term energy savings and the dual heating-cooling functionality, makes heat pumps an investment worth evaluating for most homeowners.
