Three months of hard running, then a long rest

Your air conditioner in Greenfield does most of its work in a short window. June through August, with afternoons averaging 83°F, it runs hard trying to keep up. Then it sits idle the rest of the year.

That pattern is what a tune-up checks for. Refrigerant charge that ran low over the summer. A capacitor weakened by a season of hard starts. A condenser coil coated in the dust and pollen it pulled in during those three months, cutting into how well it can shed heat. Hancock County has also logged 24 hail events and 53 damaging wind events over the past ten years, with hailstones as large as 3.4 inches, so a look at the outdoor unit's fins and cabinet is worth doing before the heat sets in again.

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.

Hancock County sets its own rule for who can do HVAC work on a house here, since Indiana leaves that decision to the counties and cities instead of running a state license itself. That means there's no state exam or state record to check. Whether a contractor needs a local license, and what that takes, depends on Hancock County's own requirements, not on anything Indianapolis sets.

For a maintenance visit on your air conditioner, the part of the job that's regulated everywhere is the refrigerant. Any technician who opens that side of the system, to check the charge or get to the coil, has to hold EPA Section 608 certification. That's a federal rule and it applies no matter what county you're in. It's not a license and it doesn't cover the rest of the visit, but it's the one credential every AC technician working on your system is required to have.

What does AC maintenance include?
A technician cleans the outdoor coil, checks the refrigerant charge, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the drain line that carries condensation away, since a clogged drain line can back up and leak into the house. They also check the thermostat and confirm the system cycles on and off the way it should. If your filter needs changing, that gets done too, since a dirty filter restricts airflow across the coil.
How often does an air conditioner need maintenance?
Once a year, ideally in spring before the cooling season starts. Around here that means getting it done before June, since homes need cooling for about three months and the afternoons average 83°F. A unit that sits idle for most of the year benefits from a check before it has to work hard every day.
Is AC maintenance worth it?
Yes, because it catches small problems while they are still small. A weak capacitor or a low refrigerant charge does not usually announce itself until the system stops cooling on a hot afternoon. Maintenance also matters more here than in some places, since the area sees frequent hail and wind storms, and a technician can spot coil damage or a bent fin before it turns into a bigger repair.
