Three months of real heat, and hail besides
Summer here runs June through August, and afternoons average 83°F. That is not extreme heat, but it is steady, and a new system needs to hold that line every one of those days without strain.
Hancock County also sees its share of hard weather. Ten years of records show 24 hail events, one hailstone as large as 3.4 inches, and 53 damaging wind events. The outdoor unit sits through all of that, so the cabinet and coil fins matter as much as the size you choose. Any new central air conditioner installed today has to meet 13.4 SEER2, the federal efficiency minimum since 2023.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Hancock County sets its own rule, not the state, so whether this job needs a license depends on the city or county office where the house sits. Indiana keeps no record of its own. There is no state list of tested contractors to check against, because the state does not test anyone for this work.
For an air conditioner installation, the protection that exists here comes from the permit, not a license. In most cities and counties, putting in a new air conditioner needs a permit from the local building office and an inspection once the work is done, and that inspection is what catches a unit set up wrong or a line run badly. That check happens at the local level, the same place that decides whether a license is required at all.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have, and which way your house faces. A unit that's too big cools the air fast but shuts off before it pulls the moisture out, so rooms feel clammy. A unit that's too small runs constantly on your hottest days and still can't keep up. A contractor will do a load calculation on your actual house to get the number right, not just go off the size of the old unit.
- Should I replace the whole system or just the outdoor unit?
- If your outdoor unit is failing but your indoor coil and furnace are newer, replacing just the outdoor unit can make sense. But the indoor coil and outdoor unit are matched to work together, and pairing a new condenser with an old coil often means you don't get the efficiency or cooling the new unit is rated for. A contractor can check the age and condition of the indoor coil and tell you whether it's compatible with a new outdoor unit or whether replacing both makes more sense.
- Do HVAC contractors in Greenfield need a state license to work on my home?
- Indiana doesn't run a statewide HVAC license, so it comes down to what Hancock County and the city require. Check with Hancock County directly on their licensing rules before hiring, since requirements vary by county across the state.
