Heat Pump Cost in Missouri 2026
A whole-home ducted heat pump costs $7,000–$13,000 installed in Missouri in 2026, with a typical job landing near $9,500. Missouri gives a heat pump a fairer fight than almost any state in the middle of the country: electricity averages 14.0 cents a kilowatt-hour, the 12th cheapest in America, while gas is dearer than it looks once the fixed charges are counted, so a good heat pump actually beats a gas furnace on fuel — something it cannot claim in Tennessee. This guide prices every system from a single mini-split head to geothermal, compares St. Louis, Kansas City, Springfield, and Columbia, stacks the Ameren and Evergy rebates that are genuinely payable in 2026, and is blunt about the federal money that is not here: the tax credit is $0, and Missouri’s HEAR rebates may not arrive until 2027 or 2028.
