Eight months of heat, and nights near 18°F
Plattsmouth homes need the furnace running from October through May, eight months of the year. On the coldest nights it's working against an average low of 18°F. A furnace sized and installed for this county gets to spend those eight months running the way it's supposed to, instead of straining to keep up.
Any new gas furnace installed now has to reach at least 80.0 percent AFUE, so most of the fuel it burns goes to heating the house rather than out the flue. Cass County has also seen 16 winter storms and 63 damaging wind events over the past ten years, and across Nebraska a quarter of households went at least a day without power in 2024. A furnace that comes back on by itself when the power returns matters here as much as one that runs efficiently every night in between.

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

Nebraska requires contractors to register with the state.
That registration puts the business on file with the state, nothing more. Nobody is tested on how to run gas line or set up a furnace correctly before their name goes on that list.
Most cities and counties require a permit for a furnace installation, along with an inspection once the work is done. That inspection is what checks the gas connection, which is the part of this job that can hurt someone if it's done wrong. In Cass County, 44% of homes heat with gas, and it's the permit and inspection that stand behind an installation like this, not the state registration.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows, and your home's layout, so there is no single number that fits every house. A contractor works this out with a load calculation, which looks at how your specific house loses heat rather than a rule of thumb. Going bigger than what the calculation shows is not a safety margin. An oversized furnace cycles on and off more often and does not run long enough to heat evenly, and an undersized one runs constantly and still falls behind on the coldest nights here.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, uneven heat between rooms, or a furnace that runs most of the day without keeping up. Age matters too. A furnace working eight months a year here, October through May, with winter nights averaging 18°F, has a lot more hours on it than one in a milder climate, so it can wear out sooner than the age alone suggests. If a contractor is telling you the same part is failing again, or the cost of fixing it keeps climbing, that is usually the point where replacing it makes more sense than repairing it again.
- Is a high-efficiency furnace worth it?
- Every non-weatherized gas furnace built new since November 2015 has to reach at least 80 percent AFUE, and high-efficiency models go higher than that. The difference matters more here than in a milder place, since homes need heat eight months of the year and winter nights average 18°F. A contractor can walk you through the actual efficiency ratings for the units they carry and what fits your home, since venting and installation differ between standard and high-efficiency furnaces.
