Five months of Terre Haute summer wears on your AC
Your air conditioner runs from May through September here, with afternoons averaging 85°F. That is five straight months of the compressor cycling on and off all day trying to keep up. The run capacitor and the condenser fan motor take that same daily wear. When a capacitor weakens, the compressor struggles to start and you hear it hum or click without kicking on. When the condenser fan goes, the unit still runs but the air coming out stops feeling cold.
Vigo County has also logged 22 hail events and 49 damaging wind events over the past ten years, with hail as large as 1.75 inches. That kind of hail can bend the thin fins on your outdoor unit's coil, and a bent coil cuts down how well it sheds heat. If your AC has run weaker since a storm, or you can see dented or flattened fins on the outdoor unit, that is often why.

A new air conditioner would save little on running costs in Vigo County, so the repair decision comes down to the unit's condition.
Estimates for a typical Vigo 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.
Vigo County sets its own rule on top of that, so whether a contractor needs a local license here depends on the county or city office, not on any state list. Some Indiana counties require one. Some don't. A few leave it to the city instead. Nothing at the state level tracks who is doing this work or how well.
For an air conditioner repair, what actually applies everywhere is federal. Touching the refrigerant side of the system requires EPA Section 608 certification, and that holds true whether or not Vigo County has its own licensing rule. That certification means a technician was tested on handling refrigerant safely and legally. It is not a local license, and it does not cover the rest of the job, like wiring or airflow. It only covers the refrigerant work itself.

- Why is my AC not blowing cold air?
- Most of the time it is a dirty air filter choking off airflow, or the refrigerant charge running low from a slow leak. A clogged filter can freeze the coil, and once that happens the air coming out will feel weak or even warm until the ice melts. Check the filter first since that part you can do yourself. If it is clean and you still get warm air, the system needs a contractor to check the refrigerant and find where it is escaping.
- Why is my AC leaking water?
- Water around your unit usually means the condensate drain line is clogged. Warm, humid air passing over the coil creates a steady drip of water that is supposed to run out through that line, and algae or dirt can block it over time. When that happens the water backs up and spills out near the indoor unit instead. A frozen coil that is now thawing will cause the same thing, so if the airflow felt weak beforehand, that could be the cause instead.
- Why won't my AC turn on?
- Start with the thermostat. Check that it is set to cool, the temperature is actually below the room temperature, and the batteries are not dead. If the thermostat looks fine, check your breaker panel, since a tripped breaker will shut the whole system down with no warning. Summer storms here bring damaging wind often enough that a breaker trip or power blip is a common reason systems stop responding. If the breaker is fine and the thermostat is calling for cooling but nothing happens, the system needs a contractor to look at it.
