Five months of Evansville heat, every year
Your air conditioner runs from May through September here, and on the afternoons that hit 87°F it doesn't get a break. That kind of steady load wears on the parts that keep it running, the capacitor, the contactor, the fan motor. A tune-up checks those parts before the heat finds the weak one for you.
Vanderburgh County has also seen 103 damaging wind events and 19 hail storms in the past ten years, with hail up to 2 inches. That kind of weather can bend the fins on your outdoor unit or knock it out of alignment without you knowing it happened. A yearly check catches that kind of damage before it turns into a summer with no cold air.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
In Indiana, HVAC licensing for homes is left to the counties and cities.
Vanderburgh County sets its own rule on top of that, so whether a contractor needs a local license here depends on whether the county or a city inside it has set one up. There is no state exam or state record to check either way. What exists, if anything, is whatever Vanderburgh County or the city the house sits in has put in place.
For a maintenance visit on an air conditioner, the part that is federal and constant is refrigerant. Anyone who opens the refrigerant side of the system to check charge or pressure during that visit has to hold EPA Section 608 certification, in Vanderburgh County or anywhere else in the country. That certification is not a local license and does not stand in for one. It is the one credential that applies no matter what the county has or has not set up.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the drain line, since a clogged drain can back up and leak into the house. They check the filter and replace it if needed, and check the thermostat calls the system correctly. On a system that has been through hail or high wind, they should also look at the condenser fins and cabinet for damage.
- How often does an air conditioner need maintenance?
- Once a year, in spring before the heat sets in. Evansville homes run the air conditioner May through September, so getting it checked before that stretch starts means it is not straining on the first 87°F afternoon. A system that ran all summer without a check is more likely to fail on the next hot day than one that was looked at in spring.
- Is AC maintenance worth it?
- Yes. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown in the middle of a hot stretch. It also means the system is not working harder than it has to through five months of cooling season, which is easier on every part of it. Skipping it does not damage anything by itself, but it means small problems go unnoticed until they become no-cool calls.
