Seven months of heat, and winters that can knock the power out
Joplin homes need heat from October through April. That's seven months a year of a furnace cycling on and off, on winter nights that average 27°F. A new furnace has to hold up to that kind of use, year after year.
Jasper County has seen 9 winter storms and 124 damaging wind events over the past ten years. In Missouri, 19% of households went at least 24 hours without power in 2024. Almost half of homes here heat with electricity, so an outage can mean no heat at all, which is worth weighing when you decide what to install. Any new gas furnace put in today has to reach at least 80 percent AFUE, the federal minimum since 2015.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, so there's no single number that works for every house. A contractor sizes a furnace by doing a load calculation on the actual house, not just a walkthrough. Going too big wastes fuel and cycles the furnace on and off more than it should. Too small, and it will run constantly through those 27°F nights and still struggle to keep up.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a rising number of repair calls. With heat needed here from October through April, a furnace that's already struggling in fall is a warning sign, not something to wait out. If a repair estimate is getting close to what a new furnace would run, that's usually the point to stop patching it. A contractor can tell you whether what you're seeing is normal wear or the furnace nearing the end of its life.
- Is a high-efficiency furnace worth it?
- It depends on how many months you're running the furnace and what you're paying for fuel now. Homes here need heat for 7 months of the year, which is long enough that efficiency differences show up on a winter's worth of bills. Every furnace made since November 2015 has to hit at least 80 percent AFUE, so the real choice is between that baseline and higher-efficiency models above it. A contractor can walk through the actual models and what each one would cost installed, since that's not something to guess at.
