Should East Ridge switch to a heat pump?
In East Ridge, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $151 saved annually, for a payback of roughly 23.2 years. East Ridge's own numbers say this pencils out only in theory, not in practice.
The climate behind East Ridge's payback figure
2547 heating degree days pile up here every year, so East Ridge has a mild winter by US standards; the cooling side runs to 2181 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 12.9°F here (record low 10.9°F), which works out to a seasonal COP of 3.01 for the cold-climate class of unit this climate calls for. East Ridge 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.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 2,143 heating kilowatt-hours annually on top of cooling, totalling about $555 a year on electricity. That compares with roughly 27 Mcf a year of gas at East Ridge's 11.84 per-Mcf rate — about $706 a year — against a local electricity rate of 13.87¢/kWh. Buy it outright, not incrementally, and payback stretches to 89.4 years; over 15 years the net position sits $1,235 behind.
If your home heats with electric baseboard instead of gas
Not every home in East Ridge has gas service. Swap the comparison to resistance heat instead of gas, and East Ridge's answer improves. The saving here runs about $731 a year, which recovers the extra $8,000 spent going electric in roughly 10.9 years.
Where East Ridge ranks in this dataset
Ranked against the other 3206 cities covered, East Ridge comes in at 2132 for heating severity — 1 would be the coldest place in the dataset — and 1785 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Where East Ridge's figure comes from
Every constant behind this page — the 3.01 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 12.9°F design temperature, East Ridge sits in cold-climate territory; the guide to that class of unit explains why.
