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 $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $217 saved annually, for a payback of roughly 16.1 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 record low of 5.2°F on file. Worked through the model, that's a seasonal COP of 2.94 on the cold-climate unit fit for this climate. Ardmore 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.

The month-to-month numbers for 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 — against a local electricity rate of 13.10¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 62.1 years, for a 15-year net position $241 behind.
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. About $653 a year comes back this way, enough that the 12.3-year payback clears the $8,000 premium comfortably within the equipment's life.
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.
Next step for 25,064 people in Ardmore
Ardmore, Oklahoma is home to about 25,064 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Ardmore, nothing is lost by holding off until the current equipment genuinely fails.

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.
