Three months of real heat, and hail before that
Summers here run June through August, and afternoons average 83°F. That is not a long season, but it is a demanding one, and a new air conditioner needs to be sized and installed to handle those afternoons without straining.
Madison County has also seen 44 hail events and 71 damaging wind events over the past ten years, with hail up to 3.5 inches recorded. An outdoor unit sits exposed to that. Any new central air conditioner installed today has to meet a federal minimum efficiency of 13.4 SEER2.

Nebraska requires contractors to register with the state.
That registration puts the business on file with the state, nothing more. Nobody tested this contractor's work, and there's no exam behind the paperwork, so the registration tells you the business exists and is on record, not that the state checked their skill.
For an air conditioner install, the protection that matters here is local. Replacing an air conditioner in most cities and counties needs a permit from the local building office, and the work gets inspected once it's done. That inspection is what checks the refrigerant lines, the electrical hookup and the installation itself, not the state registration.

- What size air conditioner does my house need?
- There is no way to answer that without looking at your house. The right size depends on your square footage, how much insulation you have, how many windows you have and which way they face, your ceiling height, and even the layout of your ductwork. A unit that is too big will cool the house fast but shut off before it pulls the humidity out, so the air feels clammy. A unit that is too small will run constantly and still struggle on the hottest afternoons. A contractor works this out with a load calculation, not a guess based on the size of your old unit.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency ratings, replacing just the outdoor unit can cause problems. The two are matched at the factory to work together, and pairing a new condenser with an old coil often means you lose efficiency and put more strain on the new compressor. A contractor can check whether your indoor coil is compatible with a new outdoor unit before deciding. If both are old, replacing the system together usually makes more sense than mixing an old part with a new one.
- Do HVAC contractors in Norfolk need a state license to work on my home?
- Nebraska does not license HVAC contractors through a trade exam. Contractors register with the Department of Labor, which is a business record, not a test of skill. What you should check instead is whether the contractor is registered and whether they pull the local permit for the job. Most cities and counties require a permit and inspection when an air conditioner is installed, and that inspection is what confirms the work meets code.
