Harrisonburg, VA: the heat pump payback math
The payback math works in Harrisonburg on paper, past the equipment's own working life. $3,500 is what Harrisonburg would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Harrisonburg's residents would see roughly $200 a year back in running costs, putting the payback around 17.5 years. Harrisonburg's own numbers say this pencils out only in theory, not in practice.
Why Harrisonburg's climate drives this number
Harrisonburg has a real but manageable winter — 4360 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 938 cooling degree days. 8.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 0.9°F on file. Worked through the model, that's a seasonal COP of 2.9 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Harrisonburg sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from SHENANDOAH VALLEY RGNL ART, the closest NOAA station, 12 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,807 heating kilowatt-hours annually on top of cooling, totalling about $764 a year on electricity. That compares with roughly 45 Mcf a year of gas at Harrisonburg's 16.79 per-Mcf rate — about $964 a year — against a local electricity rate of 16.58¢/kWh. Buy it outright, not incrementally, and payback stretches to 67.4 years; over 15 years the net position sits $498 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Harrisonburg heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,268 a year, which recovers the extra $8,000 spent going electric in roughly 6.3 years.
Harrisonburg against the rest of the country
Among 3206 cities, Harrisonburg's winter puts it at rank 1277 for severity, while its size puts it at rank 797 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Where Harrisonburg's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Harrisonburg's 2.9 seasonal COP and payback figure. Harrisonburg's 8.4°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.
