Will a heat pump pay off in East Lansing, MI?
In East Lansing, a heat pump would cost more to run each year than what you have now. 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $373 a year here, so the extra spend stays unrecovered. That's East Lansing's own climate and rates talking, not a hedge or a caveat.
East Lansing's weather, in the numbers that matter
East Lansing has a cold winter that leans hard on heating equipment — 5499 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 676 cooling degree days. Sizing runs off the design temperature, not the average day: 1°F here (record low -4°F), which works out to a seasonal COP of 2.72 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in East Lansing — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

East Lansing's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,119 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,180 a year. The gas furnace it replaces burns roughly 57 Mcf a year at 10.92 per Mcf here, for a running cost near $807 a year (electricity here runs 20.72¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $9,098 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in East Lansing heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and East Lansing's answer improves. The saving here runs about $1,886 a year, which recovers the extra $8,000 spent going electric in roughly 4.2 years.
East Lansing against the rest of the country
East Lansing lands at position 380 out of 3206 cities on heating severity (coldest is 1), and 836 out of 3206 by population size (biggest is 1). 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 East Lansing
East Lansing, Michigan is home to about 48,964 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 East Lansing, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page — the 2.72 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. East Lansing's 1°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
