Will a heat pump pay off in Wyoming, MI?

In Wyoming, 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 $349 a year here, so the extra spend stays unrecovered. That's Wyoming's own climate and rates talking, not a hedge or a caveat.

How cold Wyoming actually gets

Degree days tell the story here: Wyoming racks up 5372 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 712 cooling degree days on the cooling side. 1.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -5.1°F on file. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. Wyoming 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. Climate figures trace to the nearest NOAA station, GERALD R FORD INTERNATIONAL A, 9.3 miles from Wyoming.

The month-to-month numbers for Wyoming

Electricity use for heating alone comes out to about 4,946 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,151 a year. Wyoming's gas rate of 10.92 per Mcf, applied to the 56 Mcf a year the furnace burns, puts its running cost near $802 a year, against 20.72¢ 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 $8,728 behind.

The other scenario: no gas furnace to begin with

Not every home in Wyoming has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,859 a year, which recovers the extra $8,000 spent going electric in roughly 4.3 years.

Wyoming against the rest of the country

Among 3206 cities, Wyoming's winter puts it at rank 440 for severity, while its size puts it at rank 476 for population — 1 in both cases being the extreme. 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 Wyoming

Wyoming, Michigan is home to about 78,559 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 Wyoming, nothing is lost by holding off until the current equipment genuinely fails.

Where Wyoming's figure comes from

Every constant behind this page — the 2.75 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 1.9°F design temperature, Wyoming sits in cold-climate territory; the guide to that class of unit explains why.
