Should Tulsa switch to a heat pump?
In Tulsa, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $203 saved annually, for a payback of roughly 17.3 years. Tulsa's own numbers say this pencils out only in theory, not in practice.
The climate behind Tulsa's payback figure
2787 heating degree days pile up here every year, so Tulsa has a mild winter by US standards; the cooling side runs to 2395 cooling degree days, where summers are hot enough that cooling matters as much as heating. 0°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -2.9°F on file. Worked through the model, that's a seasonal COP of 2.7 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Tulsa — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,614 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $610 a year. The gas furnace it replaces burns roughly 29 Mcf a year at 13.99 per Mcf here, for a running cost near $813 a year (electricity here runs 13.10¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 66.6 years, for a 15-year net position $458 behind.
Electric resistance heat in Tulsa, compared
Plenty of homes in Tulsa heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Tulsa's answer improves. About $721 a year comes back this way, enough that the 11.1-year payback clears the $8,000 premium comfortably within the equipment's life.
Tulsa against the rest of the country
Among 3206 cities, Tulsa's winter puts it at rank 2008 for severity, while its size puts it at rank 48 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Deciding what's next in Tulsa, OK
About 415,154 people live in Tulsa, Oklahoma, 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.
