Is a heat pump worth it in Dearborn Heights?
Dearborn Heights is a place where a heat pump genuinely costs more to operate than the alternative. 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 $300 a year here, so the extra spend stays unrecovered. That's Dearborn Heights's own climate and rates talking, not a hedge or a caveat.
How cold Dearborn Heights actually gets
Dearborn Heights has a cold winter that leans hard on heating equipment — 5000 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 928 cooling degree days. 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 -2.9°F on file. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. Dearborn Heights 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.

Dearborn Heights's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 4,604 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,118 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 10.92 per Mcf here, for a running cost near $818 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 $8,000 behind.
Electric resistance heat in Dearborn Heights, compared
Plenty of homes in Dearborn Heights heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Dearborn Heights's answer improves. About $1,755 a year comes back this way, enough that the 4.6-year payback clears the $8,000 premium comfortably within the equipment's life.
How Dearborn Heights compares nationally
Among 3206 cities, Dearborn Heights's winter puts it at rank 695 for severity, while its size puts it at rank 654 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.
Next step for 61,040 people in Dearborn Heights
Dearborn Heights, Michigan is home to about 61,040 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 Dearborn Heights, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
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, Dearborn Heights sits in cold-climate territory; the guide to that class of unit explains why.
