Three hard months of cooling, with storms in between
Your air conditioner in Michigan City only has to carry the load from June through August. Summer afternoons average 81°F, and the unit runs hard to keep up on the hottest days, then sits idle most of the year. That start-stop pattern, packed into three months, puts real strain on the compressor and the capacitor that starts it.
LaPorte County has seen 32 hail events and 60 damaging wind storms over the past ten years, with hail up to 3.5 inches recorded. Hail dents the fins on the outdoor coil, and wind can knock the unit out of level or drive debris into it. If your AC is putting out weak or warm air, or the outdoor unit looks banged up after a storm, that damage is often why.

A new air conditioner would save little on running costs in LaPorte County, so the repair decision comes down to the unit's condition.
Estimates for a typical LaPorte County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Indiana fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana does not license HVAC contractors at the state level. That rule is left to the county and the city, so what exists here depends on where the house sits in LaPorte County, not on any statewide test or record. There is no state license to check because Indiana never created one.
For a repair on an air conditioner, the part that matters is the refrigerant line, and that is covered no matter what the local rule is. Any technician who opens that side of the system has to hold EPA Section 608 certification. That is a federal requirement, the same in every state, and it applies here regardless of what LaPorte County or its cities and townships do or do not license.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter choking off airflow across the coil, which can cause it to freeze up. Low refrigerant from a leak is another common reason, and that one needs a licensed contractor since it means opening the sealed system. Check the filter first. If it's clean and the air is still warm, the thermostat setting, the outdoor unit, or the refrigerant charge needs a closer look.
- Why is my AC leaking water?
- Your AC pulls moisture out of the air as it cools your home, and that water is supposed to drain out through a condensate line. When that line clogs with algae or dirt, the water backs up and finds another way out, usually around the indoor unit. A frozen coil that then thaws can cause the same thing, so check whether the airflow to the unit is restricted too. Either way, this is worth having looked at soon since standing water can damage the floor or ceiling around the unit.
- Why won't my AC turn on?
- Start with the thermostat. Make sure it's set to cool and a few degrees below the current room temperature, and check the batteries if it has a screen that looks dim or blank. If the thermostat looks fine, check your breaker panel for a tripped breaker, since summer afternoons here can push a strained system to shut off rather than run. If the breaker keeps tripping when you reset it, stop and call a contractor rather than resetting it again.
