Three months of real heat, and hail before that
Zionsville summers run June through August, with afternoons averaging 82°F. That is the stretch your air conditioner has to carry the house, and it needs to be sized and installed right to do it without straining.
Boone County has also logged 43 hail events and 41 damaging wind events over the past ten years, with hail as large as 2.5 inches. A new outdoor unit sits outside through all of that, so a sound installation matters as much as the equipment itself. Any new central air conditioner installed today has to meet the federal minimum of 13.4 SEER2.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Boone County sets its own rule for who can do this work, since Indiana leaves HVAC licensing to the counties and cities. Whether the installer needs a local license, and what that license required them to prove, depends on what Boone County has decided. There is no state record to check either way.
What covers this job here is the permit. Installing an air conditioner in most cities and counties calls for a permit from the local building office, and an inspection once the work is done. That inspection is what checks the installation, not a state license, since Indiana does not issue one.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated, so there's no number that applies to every home. A contractor works this out with a load calculation, not a chart based on square footage alone. Going bigger than what the calculation shows isn't a safety margin, it makes the unit cool the air fast without running long enough to pull humidity out, so the house feels clammy even at the right temperature. Summers here only run June through August, but the unit still needs to be sized for your house, not for the season.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed at the same time, replacing just the outdoor unit usually isn't a good idea. The two are matched to work together, and pairing a new outdoor unit with an old indoor coil can mean it never reaches the efficiency it's rated for, sometimes voiding the warranty outright. If the old coil has been leaking refrigerant or is corroded, that's another sign both need to go together. A contractor can check your coil's condition and tell you whether it's a real match for a new outdoor unit.
- Do HVAC contractors in Zionsville need a state license to work on my home?
- Indiana doesn't license HVAC work at the state level, it leaves that to the county and city. Zionsville sits in Boone County, so whether a license is required comes down to what Boone County has set up. Ask any contractor you're considering for their license or registration number and confirm it directly with Boone County before work starts.
