McCook asks a lot of a furnace for eight months straight
October through May, your furnace is the thing standing between you and a house that drops to 17°F on a winter night. That is eight months of work, more than half the year, with the burner cycling on and off through nights that stay cold for a long stretch.
More than half the homes in this area heat with gas, and a new furnace installed today has to hit at least 80 percent AFUE, the federal minimum for a non-weatherized gas furnace. Nebraska has seen 18 winter storms and 148 damaging wind events over the past ten years, and a quarter of households in the state lost power for at least 24 hours in 2024. A furnace that starts reliably matters most on the night the power just came back on and the house has already gone cold.

Nebraska requires contractors to register with the state.
Registration puts the business on file with the state, nothing more. Nobody tested this contractor on how to size a furnace or vent it correctly, and there is no state exam behind the paperwork. It tells you the business exists on record. It does not tell you the work will be done right.
What actually stands between you and a bad furnace install here is the local building office. A furnace replacement in most cities and counties needs a permit and an inspection once the work is done, and that inspection is what checks the gas connection and the vent, the parts where a mistake actually turns dangerous. More than half the homes in Red Willow County heat with gas, so that inspection matters here as much as anywhere.

- What size furnace does my house need?
- A contractor needs to work this out with a load calculation, not a chart based on square footage. That calculation looks at your insulation, your windows, your ceiling height, and how the house is oriented, then figures out how much heat it loses on a cold night. Here that means a night down around 17°F, so the math matters more than it would somewhere milder. A furnace that's too big will short cycle and wear out early. One that's too small will run constantly and still not keep the house warm.
- How do I know it's time to replace my furnace?
- Age is the first thing to check, along with how often it's needed a repair tech out this season. Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a gas bill that's climbed without a clear reason. If the same problem keeps coming back, that's usually the point where replacing costs less over time than fixing it again. Heat is needed here from October through May, so a furnace struggling early in that stretch is only going to have more work ahead of it.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're paying for gas now. Every furnace sold today has to hit at least 80 percent AFUE, so the real choice is between that baseline and a higher-efficiency model above it. That difference matters more here, where the furnace runs for 8 months of the year and over half of homes in Red Willow County heat with gas. A contractor can run the numbers on your gas rate and usage to say whether the higher-efficiency model pays for itself in your case.
