Kenosha County asks a lot of a furnace
Your furnace runs October through May here, eight months of the year. Winter nights average 18°F, so it has to hold a hard line most nights it runs.
75.3 percent of homes in the area heat with gas, and any non-weatherized gas furnace built after November 2015 has to reach at least 80 percent AFUE by federal rule. That is the floor, not a feature, and it applies whether you are replacing a furnace or putting one in for the first time. Wisconsin also saw 18 percent of households lose power for a day or more in 2024, and the county has logged 19 winter storms and 43 damaging wind events over the last ten years. A furnace installed here has to be sized and set up for nights that cold, for that many months, with the weather it will actually face.

Wisconsin requires contractors to register with the state.
Registration puts a contractor's business on file with the state and nothing more. There is no trade exam behind it, so it does not tell you the person working on your furnace was tested on the job. Wisconsin also keeps counties and cities from layering their own HVAC license on top, so the state record is the only one that exists here, for every contractor, in every county.
What actually covers a furnace installation is the permit process, not a license. Most cities and counties require a permit before the job starts and an inspection once it's done, and that inspection is what checks the gas connections and the venting, the parts of the job that can hurt someone if they're wrong. With most homes in Kenosha County heating with gas, that inspection is doing the job a license would do in a state that has one.

- What size furnace does my house need?
- The right size depends on your home's square footage, how well it's insulated, your window count, and your local climate, so there's no single number that fits every house. A furnace that's too big will short cycle, turning on and off before it evenly heats your home. One that's too small will run constantly during the coldest months and still struggle to keep up on an 18°F night. A contractor will measure your home and run a load calculation to size it correctly.
- How do I know it's time to replace my furnace?
- Age is the first sign, and an older furnace tends to need more repairs, each one costing more than the last. Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a rise in gas bills without a change in how you use it. Homes here need heat from October through May, so a furnace on its way out gets tested for eight months straight, and a breakdown in the middle of winter is harder to live with than one in warmer weather. If a repair keeps coming up or the furnace is old, a contractor can tell you whether it's worth fixing again or time to replace it.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you heat it. Every non-weatherized gas furnace sold new today has to reach at least 80 percent AFUE, so even a standard furnace wastes less fuel than older models did. High-efficiency units go beyond that minimum, which matters more in a place where the furnace runs eight months of the year and winter lows average 18°F. The tradeoff is a higher upfront cost against lower gas use over the furnace's life, and a contractor can walk through the numbers for your specific home.
