Four months of real heat, and hail to think about
McCook gets four months of cooling season, June through September, with summer afternoons averaging 88°F. That is not a long season, but it is a demanding one, and a new system needs to be sized and installed to handle those afternoons without straining.
Red Willow County has also seen 95 hail events and 148 damaging wind events over the past ten years, with hail up to 4 inches recorded. An outdoor condenser sits outside through all of that, so how it is installed and protected matters. Any new central air conditioner installed today also has to meet the federal minimum of 13.4 SEER2, so the baseline efficiency is already set before you even start comparing units.

Nebraska requires contractors to register with the state.
That registration puts the business on file with the state, along with basic information about who owns it and how to reach them. Nobody tests the contractor's work to get on that list, and there's no license number tied to a trade exam standing behind the job.
Since there's no state license behind this installation, the check on the work comes from the local building office instead. Air conditioner installations typically need a permit there, with an inspection once the work is finished. That inspection is what confirms the unit was installed correctly here, not a state license.

- What size air conditioner does my house need?
- It depends on your house, not just its square footage. A contractor works out the size with a load calculation that accounts for your insulation, window area, ceiling height, and how much shade your house gets. An oversized unit cools the air fast but shuts off before it pulls the humidity down, and an undersized one runs constantly on your 88 degree summer afternoons without ever catching up. Get the load calculation done rather than going by the size of the unit you had before.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are more than a few years apart in age, replacing just the outdoor unit usually is not a good option. The coil and the outdoor unit are matched to work together, and pairing an old coil with a new outdoor unit can mean you never get the efficiency or the capacity the new unit is rated for. It can also void the manufacturer's warranty on the new equipment. A contractor can check whether your existing coil will actually match with new outdoor equipment before you decide.
- Do HVAC contractors in McCook need a state license to work on my home?
- Nebraska does not license HVAC contractors through a trade exam. The state requires them to register with the Department of Labor, which is a business record, not a test of skill. What does apply to your job is a local permit. Installing a new air conditioner in most cities and counties requires a permit from the local building office and an inspection once the work is finished, so ask that it's pulled for your installation.
