A system built for nine months of heat and three of cooling
Winter nights here average 9°F, and homes in Eau Claire County need the furnace running from September through May. That's nine months of the year the heating has to work, not just a few cold snaps. Whatever you install has to be sized to hold a house steady when it's near zero outside, night after night.
Summer only asks for three months of cooling, with afternoons averaging 79°F, but the same equipment has to handle both jobs well since the two seasons run back to back almost all year. Power is worth planning around too. Close to a fifth of Wisconsin households lost power for a day or more in 2024, and the county has seen 27 winter storms and 35 damaging wind events over the past ten years. A new furnace or air conditioner is only as reliable as the power feeding it during the storm that knocks it out.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state and nothing more. Nobody tests the contractor's work before they hand over that record, so it is not a credential you can lean on the way you would a trade license. Wisconsin also does not let counties or cities step in with their own HVAC licensing, so this registration is the only state-level record that exists here, for this contractor or any other.
For a job installing a heating and cooling system, the protection you actually get comes from the permit. In most cities and counties here, that kind of installation needs a permit from the local building office, and an inspector checks the work once it is done. That inspection is where the gas connections and the rest of the installation get looked at by someone other than the person who installed them.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they should, or when the furnace or air conditioner is old enough that another breakdown feels like a matter of time. A furnace or air conditioner working harder each year to do the same job is telling you something, even if it still runs. Winters here mean nine months of heating, so a furnace that struggles in December is a bigger problem than the same furnace acting up in June. If a contractor is telling you the repair bill is close to what a new system would run, that is usually the sign to replace it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and here is why. A furnace and air conditioner installed years apart often were not matched to begin with, and pairing a new unit with one that is wearing out means paying for labor now and again soon after, instead of once. They also share the blower and ductwork, so replacing both at once lets a contractor size the whole system correctly instead of working around what is already there. If one unit is new and the other is failing, replacing just the one that failed still makes sense.
- 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 refrigerant lines, and electrical. For a furnace, that includes venting and a check of the gas connection. For an air conditioner, the outdoor unit gets set on a pad and connected to the indoor coil, then the system is charged with refrigerant to the right level. Once everything is connected, the contractor tests the system and checks airflow and temperature to confirm it is running the way it should before calling the job done.
