Five months of Kentucky summer wears on a system
Your air conditioner works hardest from May through September here, with afternoons averaging 86°F. That is five straight months of long run times, and every hour the compressor runs adds wear to the parts that keep it cooling.
Hardin County also sees its share of rough weather. Ten years of storm records show 32 hail events and 74 damaging wind events in the area, with hail up to 2.75 inches. A tune-up is when a contractor checks the outdoor unit for bent fins, a cracked cabinet, or anything storm damage or a hard summer left behind, before it turns into a system that will not start.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Kentucky requires HVAC contractors to hold a state license.
Kentucky licenses through the Department of Housing, Buildings and Construction, and the license belongs to the contractor, not to any one job. That means the same license covers a maintenance visit, a repair, or a full installation, and it is on file with the state rather than just the county or city where you live.
For maintenance on your air conditioner, that state license is what stands behind the person working on your system. Maintenance usually includes checking the refrigerant charge and inspecting the coil, and any technician who opens that side of the system, anywhere in the country, has to hold EPA Section 608 certification. In Kentucky that federal certification applies on top of the state license, not in place of it.

- What does AC maintenance include?
- A technician checks refrigerant level, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Indoors, they check the evaporator coil, the blower, and the condensate drain to make sure it isn't clogged. They also check the thermostat settings and look at electrical connections for wear. Anyone opening the refrigerant lines has to hold EPA Section 608 certification, which is a federal requirement everywhere.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts. Homes in Elizabethtown run their AC from May through September, so getting it checked in spring gives a contractor time to catch a weak capacitor or a low refrigerant charge before the summer heat sets in. A unit that runs through five months of 86°F afternoons without a check going into the season is more likely to fail when you need it most.
- Is AC maintenance worth it?
- Yes. A yearly check catches the small failures, a failing capacitor, a dirty coil, a clogged drain, before they force a breakdown. It also means the system is running clean and cooling properly through the months it actually has to work. In Elizabethtown that's May through September, with summer afternoons averaging 86°F, so the unit doesn't get much of a break.
