Nine months of heat, down to 15 above zero nights
Furnaces here run September through May. That is nine months the burner has to work, not just a few cold weeks. Winter nights average 15°F, and a furnace sized for that has to hold up night after night, not just get by.
Most homes in the county heat with gas, and any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE. That is the floor. A new installation is the chance to size the furnace and set up the venting right for what this place actually asks of it.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state, but nobody tested the contractor's work to get it. Wisconsin also blocks counties and cities from layering on their own HVAC license, so registration is the only state-level record that exists anywhere in Sheboygan County.
For a furnace install, the check that matters here is local. Most cities and counties require a permit for a furnace replacement, with an inspection once the work is done, and that inspection is what catches a bad gas connection or a venting mistake, the part of this job that can actually hurt someone. In Sheboygan County, 74.3% of homes heat with gas, so that inspection is doing real work here.

- What size furnace does my house need?
- It depends on your square footage, how well the house is insulated, your ceiling height, and how many windows you have facing north. A contractor sizes it by running a load calculation on your specific house, not by square footage alone. Two houses the same size can need different size furnaces if one has old windows and the other has new ones. Getting this right matters more here than in milder places, since your furnace runs from September through May and needs to keep up on nights averaging 15°F.
- How do I know it's time to replace my furnace?
- The clearest signs are your furnace struggling to keep the house warm, your gas bills climbing while it works harder, or a contractor telling you the heat exchanger is cracked. Age matters too. A furnace running fifteen years or more is working harder than it used to, even if it hasn't broken down yet. With heat needed here nine months a year, a furnace that's failing puts you in a tough spot fast, so it's worth having one looked at before a cold snap forces the issue rather than after.
- Is a high-efficiency furnace worth it?
- For a house here, it usually makes sense. Every new non-weatherized gas furnace sold today has to hit at least 80 percent AFUE, but high-efficiency models go higher than that, meaning less of the gas you burn goes to waste. With nine months of heating a year and winter nights averaging 15°F, that gap adds up over the season more than it would somewhere with a short, mild winter. A contractor can tell you what efficiency level makes sense for your specific house and furnace setup.
