Should Woodbury switch to a heat pump?
Woodbury is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Woodbury 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 $197 a year here, so the extra spend stays unrecovered. That's Woodbury's own climate and rates talking, not a hedge or a caveat.
How cold Woodbury actually gets
6060 heating degree days pile up here every year, so Woodbury has a cold winter that leans hard on heating equipment; the cooling side runs to 712 cooling degree days, where summers add a moderate cooling load. -5.8°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -8.3°F on file. Worked through the model, that's a seasonal COP of 2.56 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Woodbury — 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 5,994 heating kilowatt-hours annually on top of cooling, totalling about $1,034 a year on electricity. That compares with roughly 63 Mcf a year of gas at Woodbury's 10.98 per-Mcf rate — about $838 a year — against a local electricity rate of 15.67¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $6,452 behind.
The other scenario: no gas furnace to begin with
Not every home in Woodbury 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 $1,515 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.
How Woodbury compares nationally
Ranked against the other 3206 cities covered, Woodbury comes in at 192 for heating severity — 1 would be the coldest place in the dataset — and 460 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
Next step for 80,596 people in Woodbury
Woodbury, Minnesota is home to about 80,596 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 Woodbury, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Woodbury's 2.56 seasonal COP and payback figure. Woodbury's -5.8°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.
