Heat Pump Payback in Lyons, IL
Is a heat pump worth it in Lyons?
Lyons is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $151 more a year to run than the furnace it replaces, a premium with no payback. That's Lyons's own climate and rates talking, not a hedge or a caveat.

Lyons's weather, in the numbers that matter
Degree days tell the story here: Lyons racks up 4543 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1348 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 1.9°F, and the coldest daily reading in the 2024 station record was -9°F. That puts the seasonal coefficient of performance at 2.75 for the recommended cold-climate unit. Lyons needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

Lyons's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,183 heating kilowatt-hours annually on top of cooling, totalling about $1,016 a year on electricity. The gas furnace it replaces burns roughly 47 Mcf a year at $11.25 per Mcf here, for a running cost near $865 a year including the old AC (electricity here runs 19.06¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $7,767 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Lyons's result is to prices
For the verdict in Lyons to flip, electricity would need to drop to about 14.8¢/kWh from 19.06¢, or gas climb past $14.44 per Mcf from $11.25. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Lyons; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Lyons, compared
Plenty of homes in Lyons heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Lyons's answer improves. The saving here runs about $1,509 a year, which recovers the extra $10,000 spent going electric in roughly 6.6 years.
How Lyons compares nationally
Among 3206 cities, Lyons's winter puts it at rank 1174 for severity, while its size puts it at rank 3099 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Where Lyons's figure comes from
Every constant behind this page, the 2.75 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Lyons's 1.9°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.
