Heat pump vs. gas furnace in Wildwood, MO
In Wildwood, the extra upfront cost technically comes back, just not before the equipment wears out. 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. Lower bills claw that back: about $219 saved annually, for a payback of roughly 16 years. Wildwood's own numbers say this pencils out only in theory, not in practice.
The climate behind Wildwood's payback figure
Degree days tell the story here: Wildwood racks up 3990 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1370 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 0°F here (record low -8°F), which works out to a seasonal COP of 2.7 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Wildwood — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, SPIRIT OF ST LOUIS AIRPORT, 5.6 miles from Wildwood.
The month-to-month numbers for Wildwood
Electricity use for heating alone comes out to about 3,742 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $630 a year. The gas furnace it replaces burns roughly 42 Mcf a year at 14.94 per Mcf here, for a running cost near $849 a year (electricity here runs 12.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 61.7 years, for a 15-year net position $220 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Wildwood — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Wildwood's answer improves. The saving here runs about $894 a year, which recovers the extra $8,000 spent going electric in roughly 8.9 years.

About 35,082 people live in Wildwood, Missouri, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
