Boone County asks a new system to work almost all year
Winter nights here average 21°F from December through February, and homes need heat from October through May, eight months of the year. Summer afternoons average 82°F, with cooling needed June through August. Add those up and it is eleven months where your furnace or your air conditioner is doing real work, not sitting idle.
Most homes here heat with gas, and whatever system goes in has to hold up through winters cold enough to run the burner hard, night after night. Storms are part of that picture too. Boone County has logged 10 winter storms and 41 damaging wind events over the past ten years, and 17% of Indiana households went at least a day without power in 2024. A new system here needs to be sized and set up for that kind of year, not a mild one.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Whether a contractor needs a license to work in Boone County depends on what the county and its cities require, since Indiana leaves that decision to them rather than setting a state rule. There is no state license to check and no state record of who is qualified for this kind of work. Anything Boone County requires of its contractors would come from the county or city itself, not from anywhere the state keeps track of.
For an installation, the protection that does exist comes from the permit process. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, along with an inspection once the work is done. That inspection is what catches a bad gas connection or a system installed wrong, not a license number. Where that permit is required, it stands as the record that the job was done and checked.

- When should I replace my HVAC system?
- Replace your furnace or air conditioner when it needs repairs more winters or summers than not, or when it's clearly old and struggling to keep up. A furnace that short-cycles, or an air conditioner that needs a refrigerant recharge every year, is telling you it's near the end. Age matters more here than in mild climates, since your system is working October through May for heat and June through August for cooling, 11 months out of the year. If it fails during a stretch of nights near 21°F, you don't want to be deciding then. A contractor can look at your system's age and repair history and tell you where it stands.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work as one system, and a mismatched pair, an old furnace paired with a new coil, for instance, can run less efficiently and wear out sooner. If your furnace is failing but your air conditioner is only a few years old, replacing just the furnace is reasonable. A contractor can look at the age and condition of both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment, and connects it to your ductwork, gas line or electrical circuit, and condensate drain. For an air conditioner, that includes connecting the refrigerant lines and the outdoor coil to the indoor unit. For a furnace, it includes venting for exhaust and hooking up the gas or electric supply. Once everything is connected, the contractor tests the system, checks refrigerant charge or gas pressure, and confirms it's heating or cooling correctly before leaving.
