Five months of hard running in Franklin heat

Your air conditioner works from May through September here, and on the afternoons that hit 88°F it runs long stretches just to hold the house steady. That kind of run time wears on the parts that keep it going, the capacitor, the contactor, the condenser coil. A tune-up checks those before one of them quits on the hottest day of the year.

Williamson County has also seen 60 hail events and 205 damaging wind events over the past ten years. Hail up to 3 inches can bend the fins on an outdoor unit or dent the cabinet, and a service visit is a chance to catch that kind of damage before it cuts into how well the unit cools.

60 hail events: in ten years, and hail bends the fins on outdoor coils
205 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in April, before homes here start needing cooling in May.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.

What does AC maintenance include?: A technician checks the refrigerant level, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, 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 over the electrical connections, since loose wiring is a common cause of breakdowns. The filter gets checked too, since a dirty filter makes the whole system work harder.
How often does an air conditioner need maintenance?: Once a year, ideally before the cooling season starts. Homes here run their AC from May through September, so getting it checked in spring gives a technician time to catch problems before the unit has to run every day.
Is AC maintenance worth it?: Yes, because most breakdowns come from problems that build up slowly, like a dirty coil or a weak capacitor, and those show up during a routine check before they cause a failure. A system that isn't maintained also loses efficiency over time, so it runs longer to cool the same space. This area sees hail and damaging wind often enough that a yearly check is also a chance to catch storm damage to the outdoor unit early.
