Eleven months of work for a Madison County system

Your furnace and your AC in Madison County only get a short break. Heat runs October through May, eight months a year, working against winter nights that average 15°F. Cooling picks up for June through August, when afternoons average 83°F. That leaves only about one month where the system sits idle in either direction.

A new system here has to be sized for both ends of that range, not just the cold. And it needs to keep running when the power does not. Nebraska saw 25% of households lose power for at least 24 hours in 2024, and the last ten years brought 23 winter storms and 71 damaging wind events to this area. Whatever gets installed should hold up through both kinds of weather, not just the mild months in between.

Nebraska requires contractors to register with the state.

That registration puts the business on file with the Department of Labor. Nobody tested the contractor's work to get on that list, and there's no trade exam behind it the way there would be in a state that licenses contractors. It tells you the business is on record. It doesn't tell you they know how to size a heat pump or run a gas line correctly.

For this installation, the permit does the work the registration doesn't. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and an inspection once the work is done. That inspection is what checks the gas connections and the wiring, the parts of the job that can hurt someone if they're done wrong.

When should I replace my HVAC system?
Replace it when repairs start happening every year, when the unit is old enough that parts are getting hard to find, or when it can't keep up on the coldest nights or hottest afternoons anymore. Norfolk winters push down to 15°F on average, and a furnace that's struggling to hold temperature on those nights is telling you something. If a contractor has been out more than once this year for the same system, that's usually the point where replacing costs less over time than continuing to fix it. Age matters too. Most furnaces and air conditioners are built to last a couple decades, and once a system passes that mark, a breakdown in the middle of winter is a real risk, not just an inconvenience.
Should I replace my furnace and air conditioner at the same time?
If both are old, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time are matched to work as one system, and pairing an old unit with a new one can mean the new one never runs at its rated efficiency. Homes in Norfolk need heat for 8 months and cooling for only 3, so the furnace does most of the work here and tends to wear out first. If your air conditioner is still young when the furnace fails, a contractor can tell you whether it's worth keeping for now or replacing both at once.
What happens during an HVAC installation?
A contractor removes the old furnace or air conditioner, sets the new equipment in place, and connects it to the ductwork, gas line or electrical circuit, and the vent or flue it needs. They check the ducts for leaks or sizing problems, since a new system connected to bad ductwork won't heat or cool the way it's rated to. Once it's running, they test it, check refrigerant levels or gas pressure depending on what was installed, and walk through the thermostat with you. Most cities and counties, including here, require a permit for this work and an inspection once it's done, so a licensed contractor will handle that as part of the job.
