Eleven months of work a year
A new system in Greenfield spends most of the year earning its keep. Heat runs October through May, eight months, with winter nights averaging 23°F. Summer only asks for three months of cooling, but those afternoons average 83°F. Eleven months a year, something in the house is either heating or cooling it.
Most homes here heat with gas, and whatever you install has to handle those 23°F nights without strain. Hancock County has logged 11 winter storms and 53 damaging wind events over the past ten years, and in 2024, 17 percent of Indiana households lost power for a day or more. A new system should be sized and installed to hold up through that, not just the mild stretches in between.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Hancock County sets its own rule for HVAC contractors, since Indiana leaves that decision to counties and cities rather than setting one statewide. Whether a license is required here, and what it takes to get one, depends on the local building office rather than any state board. Some places test contractors before licensing them, some just keep a list of who is registered, and some have no rule at all. None of it runs through the state.
For an installation like this one, the permit is what stands between the homeowner and unchecked work. Replacing a furnace, air conditioner or heat pump in most cities and counties needs a permit from the local building office, and an inspection once the work is done. That inspection is what catches a bad gas connection or a system put in wrong, not a state license, since Indiana does not issue one.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than you want to keep spending, or when the unit is old enough that the next breakdown could leave you without heat or air. Parts wear out and efficiency drops as a system ages. If your system needs a major repair like a new heat exchanger or compressor, that's usually the point where replacement makes more sense than fixing it again. With heat needed here from October through May, a furnace that struggles in December is a real problem, not just an inconvenience.
- Should I replace my furnace and air conditioner at the same time?
- If both are close in age, yes, it's worth doing together. They're often matched to work as a system, so pairing an old furnace with a new air conditioner, or the other way around, can mean the newer unit isn't running at its best. It also means the ducts and electrical connections get checked once instead of being reworked separately for each unit. If one unit is much newer than the other, a contractor can tell you whether replacing just one makes sense for your setup.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects them to your ducts, gas line or electrical circuit, and condensate drain. They'll check that the ductwork is sized right for the new equipment and seal any leaks they find. Once everything is connected, they test the system, check refrigerant levels if there's an air conditioner involved, and walk through the thermostat with you. A contractor can tell you what your specific installation will involve based on your home and equipment.
