Should Radcliff switch to a heat pump?
In Radcliff, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Radcliff's residents would see roughly $155 a year back in running costs, putting the payback around 22.6 years. Radcliff's own numbers say this pencils out only in theory, not in practice.
Why Radcliff's climate drives this number
Degree days tell the story here: Radcliff racks up 3554 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1370 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 5°F here (record low 0.1°F), which works out to a seasonal COP of 2.82 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Radcliff — 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
Electricity use for heating alone comes out to about 3,191 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $627 a year. Radcliff's gas rate of 14.23 per Mcf, applied to the 37 Mcf a year the furnace burns, puts its running cost near $782 a year, against 14.39¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 87.2 years, for a 15-year net position $1,177 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Radcliff heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Radcliff's answer improves. The saving here runs about $923 a year, which recovers the extra $8,000 spent going electric in roughly 8.7 years.
Where Radcliff ranks in this dataset
Radcliff lands at position 1756 out of 3206 cities on heating severity (coldest is 1), and 1737 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Radcliff
About 22,706 people live in Radcliff, Kentucky, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
Where Radcliff's figure comes from
Every constant behind this page — the 2.82 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 5°F design temperature, Radcliff sits in cold-climate territory; the guide to that class of unit explains why.
