Should Oak Creek switch to a heat pump?
In Oak Creek, 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. The heat pump would cost about $298 more a year to run than the furnace it replaces — a premium with no payback. That's Oak Creek's own climate and rates talking, not a hedge or a caveat.
Oak Creek's weather, in the numbers that matter
5229 heating degree days pile up here every year, so Oak Creek has a cold winter that leans hard on heating equipment; the cooling side runs to 806 cooling degree days, where summers add a moderate cooling load. -2.9°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 2.63 on the cold-climate unit fit for this climate. Oak Creek 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. These numbers come from GENERAL MITCHELL INTERNATIONA, the closest NOAA station, 5.3 miles out.
The month-to-month numbers for Oak Creek
A 2000-square-foot house here would pull roughly 5,034 heating kilowatt-hours annually on top of cooling, totalling about $1,080 a year on electricity. That compares with roughly 54 Mcf a year of gas at Oak Creek's 10.74 per-Mcf rate — about $782 a year — against a local electricity rate of 18.87¢/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 $7,965 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Oak Creek heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,616 a year comes back this way, enough that the 5-year payback clears the $8,000 premium comfortably within the equipment's life.
Oak Creek against the rest of the country
Ranked against the other 3206 cities covered, Oak Creek comes in at 540 for heating severity — 1 would be the coldest place in the dataset — and 1078 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 Oak Creek, WI
Oak Creek, Wisconsin is home to about 38,373 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 Oak Creek, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Every constant behind this page — the 2.63 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Oak Creek's -2.9°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.
