Heat Pump Savings Calculator in Idaho

What Idaho Residents Should Know

Idaho falls in IECC climate zone 5-6B with 6,200 heating degree days per year — well above the national average. Idaho's cold winters mean heat pump COP averages 2.3 during the heating season. While this is lower than milder states, modern cold-climate heat pumps with inverter compressors can still deliver meaningful savings over traditional heating systems, especially when paired with a backup for the coldest days.

With natural gas at $0.90 per therm in Idaho, 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 Idaho 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.
