Eleven months of work, most of it in the cold
In Beaver Dam, your heating and cooling system earns its keep. Homes here need heat from October through May, eight months a year, with winter nights averaging 14°F in December through February. Summer asks for three more months of cooling, with afternoons around 80°F. That leaves one month where the system gets to rest.
A furnace here has to hold up through a long, cold stretch, and the air conditioner still has to do real work in summer. Most homes in the area heat with gas, and a standing pilot keeps working without power, which matters here. Over the past ten years, the area has seen 18 winter storms and 79 damaging wind events, and statewide, 18% of households went at least 24 hours without power in 2024. Worth asking about when you're choosing a new system.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state, but nobody tests the work. Wisconsin also keeps counties and cities from layering on their own HVAC license, so the state record is the only one that exists here.
For a heating and cooling installation, the check that matters happens at the local building office. In most cities and counties, replacing a furnace, air conditioner or heat pump needs a permit, and the finished work gets inspected before it is signed off. That permit and inspection are what stand behind the installation itself, not the state registration.

- When should I replace my HVAC system?
- Replace it when repairs start piling up or the equipment is old enough that another repair just delays the next one. A furnace that short cycles, an air conditioner that can't keep up on an 80 degree afternoon, or a system needing a second repair in a year are signs the equipment is done, not just tired. Heat is needed here from October through May, so a furnace that fails mid-winter leaves you without options when you need them most. Waiting for a full breakdown to decide is riskier than replacing on your own timeline.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed years apart often weren't matched to begin with, and pairing a new one with an aging one can mean the newer unit never runs at its best. Replacing both together also means one visit instead of two, and one system built to work as a pair. If only one has actually failed, a contractor can tell you whether the other is worth pairing with or worth replacing now too.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, connecting it to your ductwork, gas line or electrical circuit, and the vent or exhaust it needs. They test the system once it's running, checking that it reaches the right temperature, cycles correctly, and holds steady. For a full system swap, expect the crew to be at the house most of the day. Wisconsin requires HVAC contractors to register with the Department of Safety and Professional Services, so ask to see that registration before work starts.
