What a new system has to handle here
Madison County asks a lot out of a heating and cooling system. Winter nights average 22°F from December through February, and the furnace or heat pump you install needs to hold up against that for eight months, October through May. Summer afternoons average 83°F, so the same system has three months of real cooling load on top of that. Eleven months out of the year, one or the other is running.
Most homes here heat with gas, and any new gas furnace has to meet the federal minimum efficiency rating. Sizing matters too. A system too small struggles on the coldest nights, and one too large cycles more than it should. Storms are part of the picture as well. Madison County has seen 68 damaging wind events and 13 winter storms over the past ten years, and across Indiana 17% of households lost power for 24 hours or more in 2024. Whatever gets installed should be able to come back on and run when the power does.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Madison County sets whatever rule applies here, because Indiana leaves this to cities and counties instead of a state licensing board. There is no state exam behind this work and no state license number to check, since the state keeps no record of who is qualified to do it. Whatever Madison County requires, if anything, is the only local checkpoint on this job.
For a new heating and cooling system, what protects the reader here is the permit and inspection most cities and counties require for this kind of installation. That means someone from the local building office looks at the finished job, rather than a licensing board vouching for the contractor beforehand. The inspection is where a bad gas or electrical connection gets caught, since that is the dangerous part of putting in a new system. Whether that inspection happens at all depends on what Madison County's building office requires.

- When should I replace my HVAC system?
- Once your system is old enough that repairs keep coming, or a repair is priced close to what a new unit costs, replacement usually makes more sense than another patch. Age matters here because your furnace runs eight months a year, October through May, so it logs more hours than it would somewhere milder. Watch for signs like short cycling, uneven heat between rooms, or a furnace that struggles to keep up when it's 22°F outside. A contractor can look at the actual unit and tell you whether it's worth fixing again.
- Should I replace my furnace and air conditioner at the same time?
- If both units are close in age, replacing them together often makes sense, but it isn't required. Your furnace and air conditioner share a blower and the same ductwork, so a mismatched pairing can mean one part working harder than it should. If your air conditioner is only a few years old and your furnace is failing, a contractor can size a new furnace to work with what's already there. The right call depends on the condition of each unit, not just its age.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both, and connects them to your existing ductwork, gas line, and electrical. They'll check that the ducts are sized right for the new equipment, since a duct system built for an old furnace doesn't always suit a new one without some adjustment. Once everything's connected, they test the system, check for gas or refrigerant leaks, and confirm it's heating or cooling the way it should. The exact steps depend on what's being replaced and the condition of what's already in the house, so a contractor can walk you through what your job will involve.
