Eight months of heat, three of cooling
A new system in Lexington works most of the year. Heat runs October through May, and winter nights average 16°F across December through February, so the furnace or heat pump you install has to hold up through real cold. Summer asks less of it by comparison, three months of afternoons averaging 85°F, but it still has to keep up when it runs.
Almost half of homes here heat with electricity, so when the power goes out, heat goes with it. A quarter of Nebraska households lost power for at least 24 hours in 2024, and the last ten years brought 17 winter storms and 121 damaging wind events to this area. Whatever you install, it's worth asking how it holds up when the grid doesn't.

Nebraska requires contractors to register with the state.
That registration means the business is on file with the Department of Labor. It does not mean anyone tested the contractor's work or checked their trade knowledge. There is no state exam behind it and no license number tied to proven skill, just a record that the business exists.
For this installation, what stands between you and a bad job is the permit process. Putting in a new furnace, air conditioner or heat pump needs a permit from the local building office in most cities and counties, and the finished work gets inspected before it's signed off. That inspection is what catches a bad gas line or a refrigerant connection done wrong, the parts of the job that actually put a home at risk.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they used to, or the system can't keep the house warm through the winter or cool through the summer anymore. Age matters too. A furnace or air conditioner working past its expected life tends to fail at the worst time, usually the coldest night or the hottest week, because that's when it works hardest. If you're calling for the same repair again, that's the system telling you it's done, not a repair waiting to happen.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and it matters more here than in most places. Homes in this area need heat or cooling 11 months out of the year, so there's almost no stretch where one system sits idle while the other one might fail. A furnace and air conditioner installed years apart also wear at different rates, and pairing an old unit with a new one can keep the new one from running at its rated efficiency. A contractor can look at the age and condition of both and tell you whether replacing them together makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in place, then connects it to the ductwork, the gas line or electrical circuit, and the refrigerant lines. After that comes startup and testing, checking refrigerant charge, airflow, and that the thermostat is communicating with the system correctly. In most cities and counties this work needs a permit from the local building office, and an inspector checks it once the work is done. That inspection confirms the gas connections and electrical work were done to code before you're relying on the system through a Nebraska winter.
