A system built for nine months of heat and two of cooling
Winter nights here average 10°F from December through February. A furnace has to hold that line from September through May, nine months of the year. Summer is shorter work, with afternoons averaging 79°F through July and August, but a new system still has to handle that heat well when it comes.
That cold is what should drive the choice. A furnace sized for a milder winter runs longer and harder here, and the parts that start it up take the wear. Portage County has seen 27 winter storms and 44 damaging wind events over the past ten years, and across Wisconsin, 18% of households lost power for at least 24 hours in 2024. A system worth installing is sized and set up for the winters that actually happen here.

Wisconsin requires contractors to register with the state.
That registration puts the contractor's business on file with the Department of Safety and Professional Services. Nobody tests their work to get it, and the state does not grade or rank contractors against each other, so it is a record of who is in business, not a mark of skill. Wisconsin also does not let counties or cities add their own HVAC license on top of it, so this registration is what exists at the state level for a contractor in Portage County.
For an installation like this one, the protection comes from the permit process instead. In most cities and counties, replacing a furnace, air conditioner or heat pump needs a permit from the local building office, and an inspection once the work is done. That inspection is what puts someone else's eyes on the finished job, including the gas connections if the system burns gas, before it is called complete.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth or when your equipment can no longer keep up on the coldest nights. A furnace that's cycling on and off constantly, making new noises, or needing a repair call every winter is telling you something. Age matters too. Your furnace here works nine months a year, September through May, so it puts in more hours than furnaces in milder places, and that shortens its useful life. If your system is old and a repair estimate is climbing, replacement is usually the better move.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's worth doing together. Your furnace and air conditioner share the same blower and often the same coil, so a mismatched pair, one new and one worn out, can run less efficiently than a matched set. It also means one visit instead of two, and one system installed and tested at the same time by the same contractor. If your air conditioner is still young and only the furnace is failing, there's no need to replace both.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects it to your ductwork, gas line or electrical, and the vent or flue. They'll check that the ducts are sized right for the new equipment, since a system that's too big or too small for your ducts won't heat or cool evenly. Once it's connected, they test it, running it through a full cycle to check the temperature rise, airflow, and controls. A contractor can walk you through what your specific house will need before the work starts.
