Is a heat pump worth it in Macomb?

Macomb is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Macomb 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. Running costs here land $294 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Macomb's own climate and rates talking, not a hedge or a caveat.

How cold Macomb actually gets

Degree days tell the story here: Macomb racks up 4967 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 982 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -8.5°F here (record low -16.2°F), which works out to a seasonal COP of 2.5 for the cold-climate class of unit this climate calls for. Macomb 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.

The month-to-month numbers for Macomb

Modelled on a typical 2000-square-foot house, the heat pump draws about 5,031 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,118 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 11.25 per Mcf here, for a running cost near $825 a year (electricity here runs 19.06¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,909 behind.

Electric resistance heat in Macomb, compared

Not every home in Macomb 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. Switching saves about $1,521 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 5.3 years.

Macomb against the rest of the country

Among 3206 cities, Macomb's winter puts it at rank 791 for severity, while its size puts it at rank 2416 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 Macomb

Macomb, Illinois is home to about 14,765 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 Macomb, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built

Nothing above is a black box: the methodology guide shows the full arithmetic behind Macomb's 2.5 seasonal COP and payback figure. Macomb's -8.5°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
