Two months of real heat, but it counts
Stevens Point only needs cooling in July and August, with afternoons averaging 79°F. That is a short season, but the storms here are not gentle. Portage County has logged 25 hail events and 44 damaging wind events over the past ten years, with hail up to 2 inches. An outdoor condenser sits outside through all of that, coil and fan exposed to whatever comes through.
Any new central air conditioner installed today has to meet 13.4 SEER2, the federal minimum since 2023. Whatever you put in will run efficiently for the two months it works hard, and needs to hold up through the rest of the year when it is just sitting outside.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the Department of Safety and Professional Services. Nobody tested the contractor's work and no license backs it, so the record only tells you the business exists and has a state number attached to it. Wisconsin also keeps counties and cities from layering their own HVAC license on top, so this registration is the only state-level record you get anywhere in Wisconsin.
What checks the work itself, on this job, comes from the local building office. In most cities and counties, putting in a new air conditioner needs a permit before the work starts and an inspection once it is done. That inspection is what looks at the installation, not the state registration.

- What size air conditioner does my house need?
- It depends on your square footage, your ceiling height, how many windows you have and which way they face, how much insulation is in your attic and walls, and how many people live in the house. A contractor works this out with a load calculation, not a chart based on square footage alone. Getting the size right matters more than most people think. Too big and it cools the air fast but never runs long enough to pull the moisture out, so the house feels clammy. Too small and it runs constantly all July and August trying to keep up.
- Should I replace the whole system or just the outdoor unit?
- If your outdoor unit is original to the house and the indoor coil is original too, replace both together. The two are matched to work as a pair, and putting a new condenser on an old coil often means it never runs quite right, and can shorten its life. If the indoor coil was already replaced recently or is in good shape, a contractor can tell you whether it will pair with a new outdoor unit. That is a judgment call that needs someone to look at what you actually have.
- Do HVAC contractors in Stevens Point need a state license to work on my home?
- Wisconsin requires HVAC contractors to register with the state, through the Department of Safety and Professional Services. Ask to see this before work starts on your home. It is a straightforward way to know the person working on your system meets the state's requirements.
