Heat Pump Payback in Lancaster, OH
Heat pump vs. gas furnace in Lancaster, OH
Lancaster technically pencils out, but only past the point the equipment would need replacing anyway. 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 $1 saved annually, for a payback of roughly 5005.8 years. That's a technicality, not a recommendation, for anyone actually living in Lancaster.

How cold Lancaster actually gets
Lancaster has a real but manageable winter, 4461 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1003 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 7°F, and the coldest daily reading in the 2024 station record was 3°F. That puts the seasonal coefficient of performance at 2.87 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Lancaster sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Lancaster
Electricity use for heating alone comes out to about 3,936 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $882 a year. The gas furnace it replaces burns roughly 46 Mcf a year at $13.85 per Mcf here, for a running cost near $883 a year including the old AC (electricity here runs 18.40¢/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 $5,484 behind.
What would change Lancaster's answer
Gas would only overtake the heat pump in Lancaster if electricity rose past 18.4¢/kWh from 18.40¢, or gas fell under $13.83 per Mcf from $13.85. A useful quote test for Lancaster: the heat pump is worth it within a decade if it costs less than $10 more than replacing the furnace and AC, and within 7 years if the gap is under $7.
The other scenario: no gas furnace to begin with
Plenty of homes in Lancaster heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $1,436 a year comes back this way, enough that the 7-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Lancaster ranks in this dataset
Among 3206 cities, Lancaster's winter puts it at rank 1217 for severity, while its size puts it at rank 983 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Lancaster
Lancaster, Ohio is home to about 41,671 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 Lancaster, nothing is lost by holding off until the current equipment genuinely fails.

Where Lancaster's figure comes from
Every constant behind this page, the 2.87 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Lancaster's 7°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
