Marion, OH: the heat pump payback math
Here in Marion, the honest answer is that a heat pump raises your annual running cost. 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. Running costs here land $0 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Marion's numbers say wait.
Why Marion's climate drives this number
Degree days tell the story here: Marion racks up 4647 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1060 cooling degree days on the cooling side. 6.8°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 1.9°F on file. Worked through the model, that's a seasonal COP of 2.86 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Marion sits firmly in cold-climate territory, so that's the class of unit priced here.

Marion's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 4,114 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $923 a year. Marion's gas rate of 13.85 per Mcf, applied to the 48 Mcf a year the furnace burns, puts its running cost near $923 a year, against 18.40¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $3,504 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Marion — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Marion's answer improves. About $1,495 a year comes back this way, enough that the 5.4-year payback clears the $8,000 premium comfortably within the equipment's life.
How Marion compares nationally
Ranked against the other 3206 cities covered, Marion comes in at 1054 for heating severity — 1 would be the coldest place in the dataset — and 1153 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Marion
About 35,576 people live in Marion, Ohio, 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.
