Should Caledonia switch to a heat pump?

In Caledonia, a heat pump would cost more to run each year than what you have now. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Unfortunately the electric bill outweighs the gas bill it replaces by about $278 a year here, so the extra spend stays unrecovered. That's Caledonia's own climate and rates talking, not a hedge or a caveat.

How cold Caledonia actually gets

Degree days tell the story here: Caledonia racks up 5287 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 796 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 0°F, against a record low of -9°F. That puts the seasonal coefficient of performance at 2.7 for the recommended cold-climate unit. Caledonia 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.

Caledonia's running-cost comparison, in dollars

A 2000-square-foot house here would pull roughly 4,958 heating kilowatt-hours annually on top of cooling, totalling about $1,064 a year on electricity. That compares with roughly 55 Mcf a year of gas at Caledonia's 10.74 per-Mcf rate — about $786 a year — against a local electricity rate of 18.87¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,665 behind.

Electric resistance heat in Caledonia, compared

Plenty of homes in Caledonia heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,657 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 4.8 years.

How Caledonia compares nationally

Ranked against the other 3206 cities covered, Caledonia comes in at 502 for heating severity — 1 would be the coldest place in the dataset — and 1590 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Deciding what's next in Caledonia, WI

Caledonia, Wisconsin is home to about 25,240 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 Caledonia, nothing is lost by holding off until the current equipment genuinely fails.

Ask a local HVAC contractor for a quote before committing either way.

Where Caledonia's figure comes from

Nothing above is a black box: the methodology guide shows the full arithmetic behind Caledonia's 2.7 seasonal COP and payback figure. Caledonia's 0°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.
