HeatPumpPayback

Heat pump vs. gas furnace in Shawnee, KS

Shawnee technically pencils out, but only past the point the equipment would need replacing anyway. 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). Lower bills claw that back: about $129 saved annually, for a payback of roughly 27.1 years. Shawnee's own numbers say this pencils out only in theory, not in practice.

The climate behind Shawnee's payback figure

Shawnee has a real but manageable winter — 3996 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1475 cooling degree days. Sizing runs off the design temperature, not the average day: -4°F here (record low -9°F), which works out to a seasonal COP of 2.6 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Shawnee — 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, JOHNSON CO EXECUTIVE ARPT, 12.1 miles from Shawnee.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 3,892 heating kilowatt-hours annually on top of cooling, totalling about $775 a year on electricity. The gas furnace it replaces burns roughly 42 Mcf a year at 14.81 per Mcf here, for a running cost near $904 a year (electricity here runs 15.05¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 104.6 years, for a 15-year net position $1,564 behind.

Electric resistance heat in Shawnee, compared

Gas isn't universal in Shawnee — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,036 a year, which recovers the extra $8,000 spent going electric in roughly 7.7 years.

How Shawnee compares nationally

Shawnee lands at position 1509 out of 3206 cities on heating severity (coldest is 1), and 557 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Next step for 69,724 people in Shawnee

About 69,724 people live in Shawnee, Kansas, 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.

More on how this number was built

Every constant behind this page — the 2.6 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a -4°F design temperature, Shawnee sits in cold-climate territory; the guide to that class of unit explains why.
