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 $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $220 saved annually, for a payback of roughly 15.9 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 record low of -0.4°F on file. Worked through the model, that's a seasonal COP of 2.91 on the cold-climate unit fit for this climate. El Reno 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
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 — 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 61.3 years, for a 15-year net position $195 behind.
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 $8,000 spent going electric in roughly 10.8 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.
Deciding what's next in El Reno, OK
El Reno, Oklahoma is home to about 20,041 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 El Reno, nothing is lost by holding off until the current equipment genuinely fails.

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.
