Three months of real heat, then it stops
South Bend only asks a central air conditioner to work June through August. That is a short season, but summer afternoons average 81°F through all of it, so the unit runs hard while it runs.
St. Joseph County has also logged 159 damaging wind events and 51 hail events over the past ten years, including hail up to 2.5 inches. The outdoor unit sits outside through all of that, so the cabinet and the coil inside it take the weather along with the heat. Any new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2.

In Indiana, HVAC licensing for homes is left to the counties and cities.
St. Joseph County sets its own rule rather than following one from the state, so whether a contractor needs a local license depends on whether the county or the city the house sits in requires one. Where that kind of license exists, it means the contractor is on file with that office, not with the state.
For an air conditioner installation, the protection that reaches every county the same way is the permit. Most cities and counties require a permit from the local building office before the old unit comes out, and an inspection once the new one is in, and that inspection is what checks the work was done right, not a license number.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor factors in your insulation, your windows, how many rooms you have, and which way your house faces before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so rooms feel damp. An undersized one runs constantly through the summer and still can't keep up on the hottest afternoons. Have a contractor walk through your house and run the numbers rather than going by the size of the unit you had before.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if your outdoor unit is failing, the indoor coil should go with it. The two are matched to work together. Pairing a new outdoor unit with an old indoor coil can mean the system never runs at the efficiency it's rated for. Older systems also use a different refrigerant than new outdoor units are built to run on. A contractor can look at the age and condition of your indoor coil and tell you whether it's worth keeping.
- Do HVAC contractors in South Bend need a state license to work on my home?
- Indiana doesn't license HVAC contractors at the state level. That's left to counties and cities, so whether your contractor needs a license depends on St. Joseph County's own rules. It's worth asking your contractor directly which license or permit applies to the job before work starts.
