Heat Pump Payback in Plano, IL
Plano, IL: the heat pump payback math
In Plano, a heat pump would cost more to run each year than what you have now. 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 $339 more a year to run than the furnace it replaces, a premium with no payback. There's no spin on that: Plano's numbers say wait.

The climate behind Plano's payback figure
5330 heating degree days pile up here every year, so Plano has a cold winter that leans hard on heating equipment; the cooling side runs to 868 cooling degree days, where summers add a moderate cooling load. -9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -15°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.48 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Plano, 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 Aurora Municipal Airport, the closest NOAA station, 6.8 miles out.
The yearly running costs in Plano
Electricity use for heating alone comes out to about 5,442 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,178 a year. The gas furnace it replaces burns roughly 56 Mcf a year at $11.25 per Mcf here, for a running cost near $839 a year including the old AC (electricity here runs 19.06¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $10,591 behind.
What would change Plano's answer
The heat pump would become the cheaper option in Plano if electricity fell to 12.3¢/kWh (from 19.06¢) or gas rose above $17.36 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Plano, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Plenty of homes in Plano heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,608 a year, which recovers the extra $10,000 spent going electric in roughly 6.2 years.
How Plano compares nationally
Ranked against the other 3206 cities covered, Plano comes in at 459 for heating severity, 1 would be the coldest place in the dataset, and 2701 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Plano's figure comes from
Every constant behind this page, the 2.48 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Plano's -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.
