Racine County asks a lot of a new system
Winter nights here average 17°F from December through February, and heat is running somewhere in the house from October through May. That's 8 months a year on the furnace side alone. Add the 3 summer months when afternoons average 80°F, and a system here works 11 months out of the year. There's little downtime to inspect or catch a problem before the next season leans on it again.
Most homes in the area heat with gas, so a new furnace has to be sized for real cold, not a mild winter. Whatever gets installed also has to meet the federal minimum efficiency rating in place at installation, which a licensed contractor will know for your equipment type. Power matters too. 18% of Wisconsin households went at least 24 hours without power in 2024, and the area has seen 23 winter storms and 48 damaging wind events over the past ten years. A new system should be set up with that in mind, not just the temperature outside.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state. Nobody tests the contractor's work, and nothing about the job itself is checked before they are allowed to take it on. Wisconsin also does not let Racine County or its cities add their own HVAC license on top of that, so this registration is the only state-level record that exists anywhere in the state.
For a job like this one, the protection comes from the permit process instead. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what catches a bad gas connection or a mistake in how the unit was installed, not the registration.

- When should I replace my HVAC system?
- Replace it when repairs are getting more frequent or a major part fails on a system that is old enough that fixing it again just delays the same decision. A furnace or air conditioner can limp along for a while on patched repairs, but once the cost of keeping it running starts stacking up, a new system is the better bet. Watch for signs like uneven heating, rooms that never cool down, or a system that runs constantly to keep up. With heat needed here from October through May, a furnace that fails mid-winter leaves you with 17°F nights and no time to shop around, so it is worth replacing an aging system before it quits rather than after.
- 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 the same time are matched to work with each other, and replacing only one can mean pairing a new unit with an aging one that was never designed to run alongside it. That said, if your air conditioner is only a few years newer than your furnace, there is no reason to replace a system that still has years left in it. A contractor can look at the age and condition of both and tell you honestly whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or whichever units are being replaced, and sets the new equipment in place. This includes connecting the new unit to the existing ductwork, running gas and electrical lines, and installing the refrigerant lines between the air conditioner and the indoor coil. Once everything is connected, the contractor tests the system, checks refrigerant charge and airflow, and confirms the thermostat is working with the new equipment. The exact scope depends on what condition the ductwork and electrical are in, and a contractor will walk you through what your specific house needs.
