A system built for both ends of the year in Cass County
Your new furnace and AC will work most of the year here, not just a few months. Heat runs October through May, eight months, with winter nights averaging 18°F from December through February. Cooling picks up June through September when afternoons average 85°F. Only two months sit outside one job or the other.
A furnace sized for those 18°F nights needs to hold up over a long stretch of cold starts and stops. The AC needs to handle real summer heat, not just take the edge off. Nebraska sees its share of power loss too, a quarter of households went at least a day without it in 2024, and Cass County has logged 16 winter storms and 63 damaging wind events over the past ten years. Whoever installs your system should plan for weather that does more than pass through.

Nebraska requires contractors to register with the state.
Registration puts the business name on file with the Department of Labor. Nobody tests the contractor's trade knowledge to get on that list, and nobody checks their work history. It tells you the business exists and is on record in Nebraska. It does not tell you they know how to size a heat pump or vent a furnace correctly.
For a job like this, in most cities and counties, replacing a furnace, air conditioner or heat pump needs a permit from the local building office, and the finished work gets an inspection when it's done. That permit and inspection are what checks the installation itself in most places, separate from anything the state registration covers.

- When should I replace my HVAC system?
- Replace it when repairs keep happening, when a breakdown catches you at a bad time, or when a contractor tells you the repair costs more than it's worth. Homes here need heat from October through May and cooling from June through September, so there is very little of the year when either system can sit broken for long. A furnace that struggles on an 18°F night or an air conditioner losing ground at 85°F is telling you something. If the same part has already been patched more than once, that is usually the sign to stop repairing and start planning the replacement.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work as one system, and replacing only one can leave new equipment paired with an aging part that wasn't built to run alongside it. It also means one visit from the contractor and one inspection instead of two separate jobs later. If one unit is much newer than the other, there's less reason to rush the second, and a contractor can look at both and tell you whether they're worth pairing or replacing separately.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or both, and sets the new equipment in place, connecting it to the ductwork, gas line or electrical circuit, and the refrigerant lines if it's a cooling system. They test the system, check refrigerant charge and airflow, and confirm it cycles correctly before calling the job done. In most cities and counties this work needs a permit from the local building office, with an inspection once the installation is finished. The exact steps depend on what's being replaced and how the current setup is configured, which the contractor sorts out for the specific house.
