 "quick_answer": "As of November 2026, for a typical 1,800 sq ft gas-heated home on Tishomingo County E P A electricity rates in Mississippi that needs a new furnace and AC: It depends on your quotes. A heat pump saves about $260 a year to run, so it comes out ahead over 15 years if its quote is no more than $3,900 above the quote for a new furnace and AC.",
