Eight months of heat in Norfolk
Your furnace has work to do here from October through May. That is eight months a year, with winter nights averaging 15°F. A new furnace needs to hold up to that long a season, not just get through a cold snap.
More than half the homes here heat with gas, and any new gas furnace built today has to reach at least 80 percent AFUE. Nebraska has also seen its share of winter storms and damaging wind, and a quarter of households in the state went at least 24 hours without power in 2024. When the power goes out in the middle of a cold stretch, a furnace that starts back up on its own once it's restored matters.

A high-efficiency gas furnace would save about $90 a year to run in Madison County compared with a gas furnace.

Nebraska requires contractors to register with the state.
That registration puts the business on file with the state and nothing more. Nobody at the state tests the contractor's gas or furnace work before handing it out, and there's no exam behind the paperwork. It tells you the business exists on record. It doesn't tell you who's good at the job.
For a furnace install, the protection that matters comes from Madison County's building office, not the state. Replacing a furnace typically needs a permit, and the finished work gets an inspection before it's signed off. That inspection is what catches a bad gas connection or a venting mistake, the kind of error that makes a furnace dangerous rather than just broken. Over half the homes in Madison County heat with gas, so that check is doing real work here.

- What size furnace does my house need?
- There's no single number that fits every house. It depends on the square footage, how well the house holds heat, how many windows it has, and how the ductwork is laid out. A contractor will do a load calculation, room by room, to size it right. Guessing on size costs you either way. Too small and it can't keep up on a 15°F night. Too big and it short-cycles and wears out early.
- How do I know it's time to replace my furnace?
- Age is the first thing to check. Furnaces built after November 2015 have to reach at least 80 percent AFUE, so anything older than that is running on weaker efficiency rules and likely losing more heat than it should. Watch for other signs too, like the burner cycling more than it used to, rooms that won't hold a set temperature, or a repair bill that's creeping close to what a new unit runs. Homes here need heat from October through May, so a furnace on its way out doesn't get much of a break to fail quietly.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace runs and what you're paying to run it. Homes here need heat eight months of the year, with winter nights averaging 15°F, so a furnace here is working harder and longer than one in a milder climate. More than half of homes in this area heat with gas, and a high-efficiency model burns less of it to produce the same heat. A contractor can walk through the actual numbers for your house and tell you what makes sense for your setup.
