Four months of steady work in the heat

Your air conditioner in Greenwood runs June through September, and on the afternoons that hit 83°F it doesn't get much of a break. The condenser fan and compressor run long hours to keep up, and dirt on the coil or a low charge makes that work harder than it should.

Greenwood has also seen 26 hail events and 39 damaging wind events over the past ten years. Hail up to 2 inches can bend the thin fins on an outdoor coil without leaving a mark you'd notice from the ground. A tune-up gets someone looking at that coil and checking refrigerant levels before a bent fin or a slow leak turns into a system that won't cool the house.

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.

Johnson County sets its own rule for who can do this work, and that rule may or may not include a license test. Some counties and cities require one, others don't, so whether a contractor here has been tested by a licensing board depends on the local office, not on anything the state itself tracks.

What does apply everywhere, including here, is the EPA Section 608 certification. Air conditioner maintenance often means opening the refrigerant side of the system, whether to check the charge or service the coil, and any technician who does that is required to hold this federal certification no matter what county they work in.

What does AC maintenance include?
A technician checks the refrigerant charge, cleans the outdoor coil, tests the capacitor, and checks the electrical connections. They also change or check the filter and look at the condensate drain to make sure it isn't clogged. The coil matters most here since it sits outside through hail and wind all year and dirt or bent fins on it make the whole system work harder.
How often does an air conditioner need maintenance?
Once a year, ideally in spring before the heat sets in. Homes in Greenwood only run the AC from June through September, so a spring check catches anything that needs attention before those four months of 83°F afternoons arrive. Skipping a year isn't usually a problem, but skipping several lets small issues turn into bigger ones.
Is AC maintenance worth it?
Yes, mainly because it catches small problems while they're still small. A weak capacitor or a dirty coil won't stop your AC from running right away, but they make it work harder and can lead to a breakdown during the hottest part of summer. Given how often this area sees hail and high wind, having a technician look over the outdoor unit each year is worth the time.
