Should Fairview switch to a heat pump?
Fairview technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what Fairview 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. Fairview's residents would see roughly $136 a year back in running costs, putting the payback around 25.7 years. Fairview's own numbers say this pencils out only in theory, not in practice.
The climate behind Fairview's payback figure
Fairview has a mild winter by US standards — 2807 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2098 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 8.6°F, against a record low of -2.2°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. A cold-climate unit is the right call in Fairview — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, JOHN C TUNE, 19.2 miles from Fairview.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,443 kWh a year to keep it warm, plus cooling, for a combined electric bill near $587 a year. Fairview's gas rate of 11.84 per Mcf, applied to the 29 Mcf a year the furnace burns, puts its running cost near $723 a year, against 13.87¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 99 years; over 15 years the net position sits $1,454 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Fairview — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Fairview's answer improves. The saving here runs about $776 a year, which recovers the extra $8,000 spent going electric in roughly 10.3 years.
Where Fairview ranks in this dataset
Fairview lands at position 1995 out of 3206 cities on heating severity (coldest is 1), and 3082 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
