Missouri & Kansas HVAC Cost Guides by City

Missouri had 6,191,814 residents and 2,508,227 occupied homes in the U.S. Census Bureau American Community Survey 2020–2024 5-year estimates. Half of those homes were built before 1978, 70% are single-family detached houses, and the heating fuel split is 49% utility gas, 39% electricity and 8% bottled gas or propane. Missouri sits between a heating market and a cooling market, which is why heat pumps show up next to gas furnaces in our guides there.

Kansas had 2,947,197 residents and 1,174,060 occupied homes in the U.S. Census Bureau American Community Survey 2020–2024 5-year estimates. Half of those homes were built before 1976, 72% are single-family detached houses, and the heating fuel split is 63% utility gas, 27% electricity and 8% bottled gas or propane. Kansas leans harder on gas than Missouri, and more of its homes are detached houses.

This hub lists every Missouri and Kansas city guide we have published. Most of them are in the Kansas City and St. Louis areas. Each guide covers furnace installation cost, AC replacement or heat-pump-versus-furnace questions for one city and pulls that city's own Census housing data. For metro-level labor rates, electricity and gas prices and degree days, see the Kansas City and St. Louis stats pages and the HVAC Cost Stats by Metro (2026).

How to read the numbers

The figures on this page and in every linked guide come from Census survey tables. Median year built (table B25035) is the year by which half of the homes standing today had been built. In Missouri and Kansas that year is 1978, 1976, so a typical home is old enough that its original furnace, air conditioner or ductwork may already have been replaced. House heating fuel (table B25040) counts occupied homes by their main heating fuel. It shows whether a city is mostly gas, electric or propane, and that decides which equipment types fit without fuel or venting changes. Every estimate has a margin of error, which is wider for small towns, so treat small-city figures as a guide rather than an exact count. Below we list 14 city cost guides, 26 city buying guides and 4 local pages for Missouri and Kansas, sorted alphabetically.
