Is a heat pump worth it in Hazelwood?
Hazelwood sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. That premium is recovered through $242 of lower running costs every year, landing the payback clock at roughly 14.5 years. Whether that's worth it in Hazelwood depends on how many years you expect to own the place.
The climate behind Hazelwood's payback figure
Hazelwood has a real but manageable winter — 3396 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2013 cooling degree days. Sizing runs off the design temperature, not the average day: 1.9°F here (record low -7.1°F), which works out to a seasonal COP of 2.75 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Hazelwood sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from LAMBERT-ST LOUIS INTERNATIONA, the closest NOAA station, 3.1 miles out.
Hazelwood's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,127 kWh a year to keep it warm, plus cooling, for a combined electric bill near $621 a year. The gas furnace it replaces burns roughly 35 Mcf a year at 14.94 per Mcf here, for a running cost near $863 a year (electricity here runs 12.83¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 55.8 years, leaving the 15-year total $126 ahead.
The other scenario: no gas furnace to begin with
Not every home in Hazelwood 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 $817 a year comes back this way, enough that the 9.8-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Hazelwood ranks in this dataset

Nothing above is a black box: the methodology guide shows the full arithmetic behind Hazelwood's 2.75 seasonal COP and payback figure. Hazelwood's 1.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
