Heat Pump Payback in Meridian, ID
Heat pump vs. gas furnace in Meridian, ID
Meridian is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Running costs here land $73 a year higher than the furnace it replaces, so that premium is never recovered. That's Meridian's own climate and rates talking, not a hedge or a caveat.

How cold Meridian actually gets
Degree days tell the story here: Meridian racks up 5262 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1152 cooling degree days on the cooling side. 12.2°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.99 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Meridian, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,456 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $681 a year. That compares with roughly 55 Mcf a year of gas at Meridian's $7.69 per-Mcf rate, about $608 a year with the old AC included, against a local electricity rate of 12.52¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $6,588 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Meridian's result is to prices
For the verdict in Meridian to flip, electricity would need to drop to about 10.7¢/kWh from 12.52¢, or gas climb past $9.01 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 Meridian; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Meridian, compared
Gas isn't universal in Meridian, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,174 a year, which recovers the extra $10,000 spent going electric in roughly 8.5 years.
Meridian against the rest of the country
Ranked against the other 3206 cities covered, Meridian comes in at 532 for heating severity, 1 would be the coldest place in the dataset, and 203 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Meridian's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Meridian's 2.99 seasonal COP and payback figure. Meridian's 12.2°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.
