Nine months of heat, two of cooling, and winters that test the whole system
Your furnace in Sheboygan County works from September through May. Winter nights average 15°F from December through February, and on those nights the burner is cycling on and off most of the day to keep up. Summers are short and mild by comparison, with afternoons averaging 78°F through July and August, but the system still needs to switch over and handle those two months without trouble.
Most homes here heat with gas, and a new furnace has to be sized for those 15°F nights, not just an average day. The county has seen 19 winter storms and 46 damaging wind events over the past ten years, and power loss is common enough that it's worth asking how your new system handles an outage, since most furnaces and thermostats need electricity to run even when the fuel is gas.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state, nothing more. Nobody tests the contractor's work before they hand you that registration number, and no state agency is checking their installs after the fact. Wisconsin also keeps counties and cities from layering on their own HVAC license, so this registration is the only state-level record that exists anywhere in the state, whether you're in a city or out in the townships.
For a job like this, the protection that matters comes from the permit, not the registration. Installing a furnace or an air conditioner in most cities and counties means the contractor pulls a permit from the local building office, and someone comes out to inspect the work once it's done. That inspection is what catches a bad gas connection or a flue that's not vented right, the part of the job that can actually hurt someone. Whether that permit and inspection happen depends on the building office where the house sits.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is past 15 years old and starting to need repairs more than once a year, replacement usually makes more sense than another fix. Watch for weaker airflow, rooms that won't hold temperature, and a jump in energy bills without a reason. Homes here run their furnace nine months out of the year, September through May, so a system on its last legs gets tested hard and often. If it's failing now, in the middle of that stretch, waiting for spring isn't worth the risk.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at different times can end up mismatched, and that mismatch can mean the system never runs quite right, even after a repair fixes the immediate problem. Replacing both together also means one installation instead of two separate ones down the road. If only one is actually failing and the other is still young, a contractor can tell you whether it's worth pairing them or waiting.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, gas line or electrical, and condensate drain. They'll check the ducts themselves for leaks or sizing problems, since a new system connected to bad ductwork won't perform the way it should. Once it's running, they test it, check refrigerant charge or gas pressure, and walk you through the thermostat and any new controls. The exact steps depend on what you're replacing and what your house already has, so a contractor will walk you through what applies to your setup.
