Heat pump vs. gas furnace in Fairview Heights, IL
Fairview Heights is a place where a heat pump genuinely costs more to operate than the alternative. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Unfortunately the electric bill outweighs the gas bill it replaces by about $70 a year here, so the extra spend stays unrecovered. There's no spin on that: Fairview Heights's numbers say wait.
The climate behind Fairview Heights's payback figure
Degree days tell the story here: Fairview Heights racks up 3639 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1688 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, against a record low of -5.1°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 Fairview 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 ST LOUIS DOWNTOWN AIRPORT, the closest NOAA station, 8.4 miles out.
The month-to-month numbers for Fairview Heights
A 2000-square-foot house here would pull roughly 3,351 heating kilowatt-hours annually on top of cooling, totalling about $913 a year on electricity. The gas furnace it replaces burns roughly 38 Mcf a year at 11.25 per Mcf here, for a running cost near $843 a year (electricity here runs 19.06¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,545 behind.
Electric resistance heat in Fairview Heights, compared
Not every home in Fairview Heights has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,260 a year comes back this way, enough that the 6.3-year payback clears the $8,000 premium comfortably within the equipment's life.
