New Philadelphia, OH: the heat pump payback math
New Philadelphia technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what New Philadelphia 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. New Philadelphia's residents would see roughly $2 a year back in running costs, putting the payback around 2234.8 years. New Philadelphia's own numbers say this pencils out only in theory, not in practice.
Why New Philadelphia's climate drives this number
Degree days tell the story here: New Philadelphia racks up 4623 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 981 cooling degree days on the cooling side. 8.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 5°F on file. Worked through the model, that's a seasonal COP of 2.89 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in New Philadelphia — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for New Philadelphia
Electricity use for heating alone comes out to about 4,051 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $899 a year. New Philadelphia's gas rate of 13.85 per Mcf, applied to the 48 Mcf a year the furnace burns, puts its running cost near $901 a year, against 18.40¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 8619.8 years, for a 15-year net position $3,477 behind.
Electric resistance heat in New Philadelphia, compared
Gas isn't universal in New Philadelphia — 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 $1,489 a year, which recovers the extra $8,000 spent going electric in roughly 5.4 years.
New Philadelphia against the rest of the country
Ranked against the other 3206 cities covered, New Philadelphia comes in at 1067 for heating severity — 1 would be the coldest place in the dataset — and 2156 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

About 17,378 people live in New Philadelphia, Ohio, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
Where New Philadelphia's figure comes from
Every constant behind this page — the 2.89 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. New Philadelphia's 8.1°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
