Heat Pump Payback in Pocatello, ID
Should Pocatello switch to a heat pump?
Here in Pocatello, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $187 more a year to run than the furnace it replaces, a premium with no payback. That's Pocatello's own climate and rates talking, not a hedge or a caveat.

Pocatello's weather, in the numbers that matter
Degree days tell the story here: Pocatello racks up 6470 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 638 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 3°F here (coldest 2024 reading -14.1°F), which works out to a seasonal COP of 2.77 for the cold-climate class of unit this climate calls for. Pocatello needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

Pocatello's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,914 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $809 a year. The gas furnace it replaces burns roughly 67 Mcf a year at $7.69 per Mcf here, for a running cost near $622 a year including the old AC (electricity here runs 12.52¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $8,303 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Pocatello
For the verdict in Pocatello to flip, electricity would need to drop to about 9.2¢/kWh from 12.52¢, or gas climb past $10.46 per Mcf from $7.69. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Pocatello; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Pocatello heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Pocatello's answer improves. The saving here runs about $1,346 a year, which recovers the extra $10,000 spent going electric in roughly 7.4 years.

Where Pocatello's figure comes from
Every constant behind this page, the 2.77 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Pocatello's 3°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
