 "quick_answer": "As of November 2026, for a typical 1,800 sq ft electrically heated home on Hawaiian Electric (Hawaii Island) electricity rates in Hawaii that needs a new furnace and AC: It depends on your quotes. A high-efficiency cold-climate heat pump saves about $480 a year to run, so it comes out ahead over 15 years if its quote is no more than $7,100 above the quote for a new furnace and AC.",
