Is a heat pump worth it in Dyersburg?
Dyersburg technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Dyersburg's residents would see roughly $120 a year back in running costs, putting the payback around 29.2 years. Dyersburg's own numbers say this pencils out only in theory, not in practice.
Why Dyersburg's climate drives this number
Degree days tell the story here: Dyersburg racks up 2295 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1913 cooling degree days on the cooling side. 7°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 2.87 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Dyersburg sits firmly in cold-climate territory, so that's the class of unit priced here.

Dyersburg's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,025 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $507 a year. The gas furnace it replaces burns roughly 24 Mcf a year at 11.84 per Mcf here, for a running cost near $627 a year (electricity here runs 13.87¢/kWh). Buy it outright, not incrementally, and payback stretches to 112.7 years; over 15 years the net position sits $1,703 behind.
The other scenario: no gas furnace to begin with
Not every home in Dyersburg has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $643 a year comes back this way, enough that the 12.4-year payback clears the $8,000 premium comfortably within the equipment's life.
Dyersburg against the rest of the country
Among 3206 cities, Dyersburg's winter puts it at rank 2278 for severity, while its size puts it at rank 2305 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
