Kenosha summers are short, but they still test your AC
Cooling season here runs June through August, about three months a year, with summer afternoons averaging 80°F. Your air conditioner spends most of the year sitting idle, then has to work through those three months without trouble.
Kenosha County has also seen its share of hail and wind, 17 hail events and 43 damaging wind events over the past ten years, with hailstones up to 2.9 inches. An outdoor condenser sits exposed to that weather, so how it's installed and protected matters. Any new central air conditioner installed today has to meet a federal minimum efficiency of 13.4 SEER2.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the Department of Safety and Professional Services. Nobody is tested to get on that list, so it tells you the contractor exists in the state's records, not that anyone checked their work. Wisconsin also keeps counties and cities from adding their own HVAC license on top of it, so this registration is the only state-level record you will find anywhere in Wisconsin.
For an air conditioner installation, the protection that matters comes from the local building office. In most cities and counties the job needs a permit, and an inspection once the work is done, and that inspection is what checks the installation itself. That permit and inspection are what stand behind the work here, not the state registration.

- What size air conditioner does my house need?
- There's no single number for every house, it depends on your square footage, how much shade your house gets, how well it's insulated, and the layout of your rooms. A unit that's too big will cool the air fast but shut off before it pulls the humidity out, leaving the house feeling clammy. Too small and it will run constantly on those 80°F summer afternoons and still struggle to keep up. A contractor will measure your house and figure the load before recommending a size, so you're not guessing.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so swapping just one often means putting a new coil next to an old one that isn't built to work with it. That mismatch can cost you efficiency and put strain on the new equipment. If your indoor coil and ductwork are still in good shape and your system is younger, a contractor might be able to replace just the outdoor unit. A contractor can look at both halves of your system and tell you what actually pairs up.
- Do HVAC contractors in Kenosha need a state license to work on my home?
- Wisconsin doesn't issue a trade-specific HVAC license, but contractors are required to register with the state's Department of Safety and Professional Services. That registration is what to check for before letting anyone work on your system. It's worth asking to see it, since it's your way of knowing the contractor is on record with the state.
