Heat Pump Payback in Ardmore, OK
Ardmore, OK: the heat pump payback math
The payback math works in Ardmore on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $217 saved annually, for a payback of roughly 25.3 years. That's a technicality, not a recommendation, for anyone actually living in Ardmore.

How cold Ardmore actually gets
Degree days tell the story here: Ardmore racks up 2343 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2414 cooling degree days on the cooling side. 10.2°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 5.2°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.94 on the cold-climate unit fit for this climate. Mild on average, but the occasional cold snap is what sizes the equipment: at a 10.2°F design temperature Ardmore falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe.

The yearly running costs in Ardmore
A 2000-square-foot house here would pull roughly 2,018 heating kilowatt-hours annually on top of cooling, totalling about $534 a year on electricity. That compares with roughly 24 Mcf a year of gas at Ardmore's $13.99 per-Mcf rate, about $751 a year with the old AC included, against a local electricity rate of 13.10¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $2,241 behind.
How sensitive Ardmore's result is to prices
Gas would only overtake the heat pump in Ardmore if electricity rose past 36.0¢/kWh from 13.10¢, or gas fell under $5.09 per Mcf from $13.99. A useful quote test for Ardmore: the heat pump is worth it within a decade if it costs less than $2,170 more than replacing the furnace and AC, and within 7 years if the gap is under $1,519.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Ardmore, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Ardmore ranks in this dataset
Ardmore lands at position 2260 out of 3206 cities on heating severity (coldest is 1), and 1603 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Ardmore's figure comes from
Every constant behind this page, the 2.94 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Ardmore's 10.2°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
