HeatPumpPayback

Heat pump vs. gas furnace in Lyndon, KY

The payback math works in Lyndon on paper, past the equipment's own working life. $3,500 is what Lyndon 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. Lower bills claw that back: about $162 saved annually, for a payback of roughly 21.6 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, against a record low of 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 — against a local electricity rate of 14.39¢/kWh. Buy it outright, not incrementally, and payback stretches to 83.3 years; over 15 years the net position sits $1,068 behind.

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 $8,000 spent up front comes back in about 8.4 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 for 11,221 people 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.
