Heat Pump Payback in Sterling, CO
Heat pump vs. gas furnace in Sterling, CO
Here in Sterling, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $210 a year here, so the extra spend stays unrecovered. That's Sterling's own climate and rates talking, not a hedge or a caveat.

Sterling's weather, in the numbers that matter
5817 heating degree days pile up here every year, so Sterling has a cold winter that leans hard on heating equipment; the cooling side runs to 875 cooling degree days, where summers add a moderate cooling load. -5.8°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -23.8°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.56 on the cold-climate unit fit for this climate. Sterling 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. Climate figures trace to the nearest NOAA station, Sterling Municipal Airport, 3.9 miles from Sterling.
Sterling's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,754 heating kilowatt-hours annually on top of cooling, totalling about $1,074 a year on electricity. The gas furnace it replaces burns roughly 61 Mcf a year at $11.17 per Mcf here, for a running cost near $864 a year including the old AC (electricity here runs 16.53¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $8,654 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Sterling
For the verdict in Sterling to flip, electricity would need to drop to about 12.6¢/kWh from 16.53¢, or gas climb past $14.64 per Mcf from $11.17. 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 Sterling; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Sterling, compared
Gas isn't universal in Sterling, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,548 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 6.5 years.
How Sterling compares nationally
Sterling lands at position 279 out of 3206 cities on heating severity (coldest is 1), and 2637 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
