Heat Pump Payback in Lyndon, KY
Heat pump vs. gas furnace in Lyndon, KY
The payback math works in Lyndon on paper, past the equipment's own working life. $5,500 is what Lyndon would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $162 saved annually, for a payback of roughly 33.9 years. That's a technicality, not a recommendation, for anyone actually living in Lyndon.

How cold Lyndon actually gets
Degree days tell the story here: Lyndon racks up 3632 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1460 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 5°F, and the coldest daily reading in the 2024 station record was 1.9°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. A cold-climate unit is the right call in Lyndon, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Bowman Field Airport, the closest NOAA station, 4.8 miles out.
Lyndon's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,261 heating kilowatt-hours annually on top of cooling, totalling about $648 a year on electricity. That compares with roughly 38 Mcf a year of gas at Lyndon's $14.23 per-Mcf rate, about $811 a year with the old AC included, against a local electricity rate of 14.39¢/kWh. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $3,068 behind.
The break-even point in Lyndon
Gas would only overtake the heat pump in Lyndon if electricity rose past 20.6¢/kWh from 14.39¢, or gas fell under $9.94 per Mcf from $14.23. A useful quote test for Lyndon: the heat pump is worth it within a decade if it costs less than $1,620 more than replacing the furnace and AC, and within 7 years if the gap is under $1,134.
If your home heats with electric baseboard instead of gas
Not every home in Lyndon has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $947 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 10.6 years.
Where Lyndon ranks in this dataset
Lyndon lands at position 1730 out of 3206 cities on heating severity (coldest is 1), and 2940 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
Next step if you live in Lyndon
Lyndon, Kentucky is home to about 11,221 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 Lyndon, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Lyndon's 2.82 seasonal COP and payback figure. Lyndon's 5°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
