Will a heat pump pay off in Florence, KY?
Florence technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what Florence 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. Florence's residents would see roughly $159 a year back in running costs, putting the payback around 22 years. That's a technicality, not a recommendation, for anyone actually living in Florence.
How cold Florence actually gets
4009 heating degree days pile up here every year, so Florence has a real but manageable winter; the cooling side runs to 1384 cooling degree days, where summers are hot enough that cooling matters as much as heating. 3.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -2°F on file. Worked through the model, that's a seasonal COP of 2.79 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Florence sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from CINCINNATI/NORTHERN KENTUCKY, the closest NOAA station, 3.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,638 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $693 a year. That compares with roughly 42 Mcf a year of gas at Florence's 14.23 per-Mcf rate — about $852 a year — against a local electricity rate of 14.39¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 85 years, leaving the 15-year total $1,117 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Florence heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Florence's answer improves. About $1,026 a year comes back this way, enough that the 7.8-year payback clears the $8,000 premium comfortably within the equipment's life.
Florence against the rest of the country
Ranked against the other 3206 cities covered, Florence comes in at 1498 for heating severity — 1 would be the coldest place in the dataset — and 1218 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
What to do with this number in Florence
Florence, Kentucky is home to about 33,763 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 Florence, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 2.79 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Florence's 3.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
