Heat Pump Payback in Streamwood, IL
Streamwood, IL: the heat pump payback math
Here in Streamwood, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Streamwood would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $295 a year here, so the extra spend stays unrecovered. That's Streamwood's own climate and rates talking, not a hedge or a caveat.

Streamwood's weather, in the numbers that matter
Degree days tell the story here: Streamwood racks up 5064 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 915 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 -7.1°F, and the coldest daily reading in the 2024 station record was -14.1°F. That puts the seasonal coefficient of performance at 2.53 for the recommended cold-climate unit. A cold-climate unit is the right call in Streamwood, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Streamwood's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,068 heating kilowatt-hours annually on top of cooling, totalling about $1,115 a year on electricity. That compares with roughly 53 Mcf a year of gas at Streamwood's $11.25 per-Mcf rate, about $819 a year with the old AC included, against a local electricity rate of 19.06¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $9,930 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Streamwood's answer
For the verdict in Streamwood to flip, electricity would need to drop to about 12.7¢/kWh from 19.06¢, or gas climb past $16.85 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 Streamwood; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Streamwood heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Switching saves about $1,555 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 6.4 years.
Streamwood against the rest of the country
Among 3206 cities, Streamwood's winter puts it at rank 629 for severity, while its size puts it at rank 1079 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Streamwood
Streamwood, Illinois is home to about 38,360 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 Streamwood, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
