Heat Pump Payback in Lebanon, OH
Heat pump vs. gas furnace in Lebanon, OH
Lebanon technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Lower bills claw that back: about $8 saved annually, for a payback of roughly 667.5 years. That's a technicality, not a recommendation, for anyone actually living in Lebanon.

Lebanon's weather, in the numbers that matter
Lebanon has a real but manageable winter, 4083 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1300 cooling degree days. Sizing runs off the design temperature, not the average day: 3°F here (coldest 2024 reading 3°F), which works out to a seasonal COP of 2.77 for the cold-climate class of unit this climate calls for. Lebanon 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.

Lebanon's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,732 kWh a year to keep it warm, plus cooling, for a combined electric bill near $891 a year. Lebanon's gas rate of $13.85 per Mcf, applied to the 43 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $899 a year, against 18.40¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $5,376 behind.
What would change Lebanon's answer
Gas would only overtake the heat pump in Lebanon if electricity rose past 18.7¢/kWh from 18.40¢, or gas fell under $13.66 per Mcf from $13.85. A useful quote test for Lebanon: the heat pump is worth it within a decade if it costs less than $80 more than replacing the furnace and AC, and within 7 years if the gap is under $56.
If your home heats with electric baseboard instead of gas
Not every home in Lebanon has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,322 a year comes back this way, enough that the 7.6-year payback clears the $10,000 premium comfortably within the equipment's life.
How Lebanon compares nationally
Ranked against the other 3206 cities covered, Lebanon comes in at 1464 for heating severity, 1 would be the coldest place in the dataset, and 1783 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
Next step if you live in Lebanon
Lebanon, Ohio is home to about 21,995 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 Lebanon, nothing is lost by holding off until the current equipment genuinely fails.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Lebanon's 2.77 seasonal COP and payback figure. At a 3°F design temperature, Lebanon sits in cold-climate territory; the guide to that class of unit explains why.
