How Missouri homes are heated
Gas is the default in Missouri, and propane is more common than in most states. The Census Bureau’s table B25117 for 2020-2024 shows 914,544 of 1,708,413 owner-occupied homes heated mainly by utility gas, 53.5%. Electricity heats 31.9%, and 176,549 owner homes, 10.3%, use bottled, tank or LP gas, which ranks 14th among the 50 states. Wood is the main fuel in another 54,452 owner homes.
| Heating fuel | Owner-occupied homes | Share | Source |
|---|---|---|---|
| Utility gas | 914,544 | 53.5% | ACS 2020-2024, B25117 |
| Electricity | 545,546 | 31.9% | ACS 2020-2024, B25117 |
| Bottled, tank or LP gas | 176,549 | 10.3% | ACS 2020-2024, B25117 |
| Wood | 54,452 | 3.2% | ACS 2020-2024, B25117 |
| Fuel oil, kerosene, coal, solar and other fuels | 12,452 | 0.7% | ACS 2020-2024, B25117 |
| No fuel used | 4,870 | 0.3% | ACS 2020-2024, B25117 |
With renters included, table B25040 (2020-2024 ACS) shows 49.3% of 2,508,227 occupied homes on utility gas and 38.8% on electricity. The fuel tells an HVAC buyer what a replacement looks like: a gas furnace with a matched air conditioner in most owner homes, a heat pump or electric furnace in about a third, and a propane furnace with its own tank in many rural ones. The table describes the housing and makes no claim about lead share.
Heating and cooling demand in Missouri
Missouri sits in the middle of the national range on both measures, which is what makes it a two-season HVAC state. The heating degree day series from NOAA NCEI recorded 4,678 for 2025, below the 1991-2020 average of 4,980 and 27th of the 48 states with a series.
Summers are hot enough to rank higher. The cooling degree day series shows 1,414 for 2025, above the 1991-2020 average of 1,265 and 15th of 48. A Missouri system works through a real winter and a real summer, so both the furnace and the air conditioner wear out on their own schedules. Compared with the 30-year average, 2025 came in 302 heating degree days lower and 149 cooling degree days higher: a milder winter and a warmer summer than usual in the same NCEI series.
About the numbers: NCEI subtracts each day’s mean temperature from 65°F (or the reverse, for cooling), totals the result for the calendar year, and the 1991-2020 figure averages the 30 annual totals from that statewide series.
Missouri owners and renters for HVAC buyers
The Census Bureau’s table B25003 counts 1,708,413 owner-occupied homes and 799,814 renter-occupied homes in Missouri for 2020-2024, out of 2,508,227 occupied. Owners decide on furnace and air conditioner replacements. A renter may call in a no-heat or no-cooling problem, but the owner of the building normally approves new equipment. Renters hold 31.9% of occupied Missouri homes in that table, so roughly two households in three own the home they live in; homeowner status is one of the filters further down this page.
Missouri’s housing age, home values and energy code status are on Missouri window replacement leads, so this page leaves them out.
Missouri counties by owner-occupied homes

| St. Louis city | 65,612 | 81.0% | 17.0% | ACS 2020-2024, B25003 and B25117 (county) |
| Boone | 44,178 | 56.5% | 32.0% | ACS 2020-2024, B25003 and B25117 (county) |
| Franklin | 32,930 | 15.9% | 64.3% | ACS 2020-2024, B25003 and B25117 (county) |
| Cass | 32,678 | 55.5% | 30.2% | ACS 2020-2024, B25003 and B25117 (county) |
The metro core is almost all gas: 83.6% of owner homes in St. Louis County, 81.0% in St. Louis city and 79.8% in Jackson County on the Kansas City side. Farther out the picture changes. Franklin County is 64.3% electric with 12.2% on propane, and Jefferson County is 53.6% electric, in the same county data (2020-2024 ACS).
Propane also stands out in Cass County, where 11.4% of owner homes use it, and in Boone County at 9.4%, both well above the 1.3% in St. Louis County. Propane does not have its own column in the table above, so those shares are given here from the B25117 county table (2020-2024 ACS).
Reading the Missouri numbers before choosing ZIP codes
Taken together, the Missouri figures describe a gas-heated metro core, an electric and propane fringe, and equipment that runs hard in both seasons. Three points for a buyer:
- Furnace work is concentrated. St. Louis County, St. Louis city, Jackson, Clay and St. Charles counties all have more than 70% of owner homes on utility gas in the ACS county table (2020-2024 ACS). A buyer with gas furnace installers can center its coverage on those two metro areas.
- Rural propane needs its own skills. Statewide, 10.3% of owner homes use bottled, tank or LP gas in table B25117 (2020-2024 ACS), and the share passes 11% in Franklin and Cass counties. Propane furnaces and tank connections are a different job from a utility gas hookup.
- Both seasons matter. The NCEI series logged 4,678 heating and 1,414 cooling degree days in 2025, so a Missouri buyer that quotes only one side of the system covers only part of the year.
These points are drawn from the official housing and climate data on this page. They do not estimate the number of leads in any Missouri county.
What Missouri HVAC buyers filter on
Missouri HVAC buyers filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary on the same kinds of fields as other home services buyers. How each one connects to the data above:
- Project type: for example install, replace or repair, for heating or cooling. With two full seasons, buyers often take both heating and cooling projects.
- Homeowner status: the state’s 1,708,413 owner-occupied homes are where replacement decisions are made (ACS 2020-2024, B25003).
- Timeframe: a no-heat call in January needs a faster response than a planned upgrade.
- ZIP code: a buyer chooses ZIP codes its crews can reach, such as the gas-heated St. Louis and Kansas City counties or the propane-heavy rural ones.
When HVAC opens, Missouri buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. The complete field list appears on the sample HVAC lead.
Where buyers filter in Missouri
Missouri’s two biggest HVAC markets straddle state lines: the St. Louis metro reaches into Illinois and the Kansas City metro into Kansas. Below are the six largest metro areas with Missouri counties in the Census Bureau’s July 1, 2025 estimates. Once HVAC opens, buyers will be able to set coverage on any ZIP code, inside these areas or outside them.
- St. Louis, MO-IL: 2,814,421 (July 1, 2025 estimate, whole metro area)
- Kansas City, MO-KS: 2,270,682 (July 1, 2025 estimate, whole metro area)
- Springfield: 500,694 (July 1, 2025 estimate)
- Columbia: 219,062 (July 1, 2025 estimate)
- Joplin, MO-KS: 208,796 (July 1, 2025 estimate, whole metro area)
- Jefferson City: 152,712 (July 1, 2025 estimate)
