Five months of Terre Haute summer adds up fast
Your air conditioner runs from May through September here, with summer afternoons averaging 85°F. That's five straight months of the compressor cycling on and off to keep up, day after day, with little rest between.
Vigo County has also seen 22 hail events and 49 damaging wind events over the past ten years, with hail as large as 1.75 inches. That kind of weather can bend the fins on your outdoor unit or knock it out of alignment without leaving damage you'd notice from a distance. A tune-up checks the coil and the cabinet for that kind of harm, along with the wear that five months of steady runtime puts on the parts that keep your system cooling.

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.
Vigo County sets its own rule on this, not the state. Some counties and cities in Indiana require HVAC contractors to hold a local license, and some do not, so whether this job requires one depends on whether Vigo County or the city within it has that requirement on the books. Where a local license exists, it means the county or city has tested and recorded that contractor. Where none exists, there is no such record at all.
For a maintenance visit on an air conditioner, the technician is going into the refrigerant side of the system to check charge and pressures, and federal law requires EPA Section 608 certification for that work in every state, Indiana included. That certification is not a local license and does not depend on where the house sits. It is the one credential that applies to this job no matter what Vigo County decides about the rest.

- What does AC maintenance include?
- A technician cleans the condenser coil outside and checks refrigerant pressure, since dirt on that coil is one of the main reasons a system loses cooling power. They check the capacitor and contactor, the electrical parts that get the compressor running, and test the thermostat's connection to the system. They also check the condensate drain, because a clogged one lets water back up into the house. If your system has a belt-driven blower, they check that too, though most residential systems today are direct-drive with no belt.
- How often does an air conditioner need maintenance?
- Once a year, before the season it works hardest. Here that means getting it looked at before May, so it is ready for the five months of cooling that follow. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown in the middle of a hot afternoon.
- Is AC maintenance worth it?
- Yes, because most of what shortens an air conditioner's life is the kind of thing a yearly check catches early. A dirty coil or a failing capacitor makes the compressor work harder than it should, and that wear adds up over a summer of 85°F afternoons. It also matters here because hail and wind are real risks, with 22 hail events and 49 damaging wind events recorded in the area over the last ten years. A maintenance visit is a good time to have the outdoor unit checked for storm damage that might not be obvious from a glance.
