Heat Pump Payback in Palos Heights, IL
Is a heat pump worth it in Palos Heights?
Here in Palos Heights, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Palos Heights 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 $151 a year here, so the extra spend stays unrecovered. There's no spin on that: Palos Heights's numbers say wait.

Why Palos Heights's climate drives this number
Degree days tell the story here: Palos Heights 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. A cold-climate unit is the right call in Palos Heights, 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 Chicago Midway International Airport, the closest NOAA station, 8.8 miles out.
The yearly running costs in Palos Heights
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,183 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,016 a year. That compares with roughly 47 Mcf a year of gas at Palos Heights's $11.25 per-Mcf rate, about $865 a year with the old AC included, against a local electricity rate of 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 $7,767 behind.
What would change Palos Heights's answer
The heat pump would become the cheaper option in Palos Heights if electricity fell to 14.8¢/kWh (from 19.06¢) or gas rose above $14.44 per Mcf (from $11.25). At today's prices a cheaper quote cannot rescue the gas comparison in Palos Heights, since there is no yearly saving to recover it from.
The other scenario: no gas furnace to begin with
Plenty of homes in Palos Heights heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Palos Heights's answer improves. About $1,509 a year comes back this way, enough that the 6.6-year payback clears the $10,000 premium comfortably within the equipment's life.
