Heat Pump Payback in El Reno, OK
El Reno, OK: the heat pump payback math
In El Reno, 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 $5,500 more up front here. Lower bills claw that back: about $220 saved annually, for a payback of roughly 25 years. That's a technicality, not a recommendation, for anyone actually living in El Reno.

El Reno's weather, in the numbers that matter
2789 heating degree days pile up here every year, so El Reno has a mild winter by US standards; the cooling side runs to 2271 cooling degree days, where summers are hot enough that cooling matters as much as heating. 8.6°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -0.4°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.91 on the cold-climate unit fit for this climate. Mild on average, but the occasional cold snap is what sizes the equipment: at a 8.6°F design temperature El Reno 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.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,427 kWh a year to keep it warm, plus cooling, for a combined electric bill near $572 a year. That compares with roughly 29 Mcf a year of gas at El Reno's $13.99 per-Mcf rate, about $792 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 $2,195 behind.
How sensitive El Reno's result is to prices
Gas would only overtake the heat pump in El Reno if electricity rose past 28.6¢/kWh from 13.10¢, or gas fell under $6.40 per Mcf from $13.99. A useful quote test for El Reno: the heat pump is worth it within a decade if it costs less than $2,200 more than replacing the furnace and AC, and within 7 years if the gap is under $1,540.
Electric resistance heat in El Reno, compared
Gas isn't universal in El Reno, 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 $739 a year, which recovers the extra $10,000 spent going electric in roughly 13.5 years.
El Reno against the rest of the country
El Reno lands at position 2006 out of 3206 cities on heating severity (coldest is 1), and 1919 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where El Reno's figure comes from
Every constant behind this page, the 2.91 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. El Reno's 8.6°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
