HeatPumpPayback

Will a heat pump pay off in Flint, MI?

Here in Flint, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Flint would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Unfortunately the electric bill outweighs the gas bill it replaces by about $375 a year here, so the extra spend stays unrecovered. There's no spin on that: Flint's numbers say wait.

Why Flint's climate drives this number

Flint has a cold winter that leans hard on heating equipment — 5352 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 700 cooling degree days. Sizing runs off the design temperature, not the average day: -0.9°F here (record low -0.9°F), which works out to a seasonal COP of 2.68 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Flint — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 5,057 heating kilowatt-hours annually on top of cooling, totalling about $1,171 a year on electricity. The gas furnace it replaces burns roughly 56 Mcf a year at 10.92 per Mcf here, for a running cost near $797 a year (electricity here runs 20.72¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $9,122 behind.

If your home heats with electric baseboard instead of gas

Gas isn't universal in Flint — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $1,825 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.4 years.

Flint against the rest of the country

Ranked against the other 3206 cities covered, Flint comes in at 450 for heating severity — 1 would be the coldest place in the dataset — and 467 by population, where 1 is largest. 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 Flint

About 79,735 people live in Flint, Michigan, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
