Two months of real work, then months of sitting still

Your air conditioner only earns its keep in July and August here. Summer afternoons average 75°F, mild compared to most places, so the compressor isn't pushed hard when it does run.

The bigger risk is what happens the other ten months. A unit that sits idle can seize up or leak refrigerant slowly without anyone noticing, and Lincoln County has seen its share of rough weather in that time. Nineteen damaging wind events and a few hail storms have hit the area over the past ten years, enough to bend fins, knock the unit out of level, or drive debris into the coil. A tune-up before summer catches that kind of damage while it's still a small fix, not a breakdown on the first hot day.

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 refrigerant pressure, cleans the outdoor coil, and tests the capacitor and contactor. They also check the indoor coil, change or check the filter, and confirm the thermostat is calling for cooling correctly. Part of the visit is looking for early wear, a weak capacitor or a coil that is starting to clog, before it causes a breakdown.
How often does an air conditioner need maintenance?
Once a year, before the season it will run in. Here that means getting it checked before July, since cooling season is really just July and August. A yearly check catches a weak part while it can still be replaced on a schedule, not during a heat wave.
Is AC maintenance worth it?
Yes, mainly because it catches small problems while they are still small. A dirty coil or a weak capacitor makes the unit work harder and fail sooner, and both are easy to spot during a maintenance visit. With only two months of real cooling need here, a unit that sits unused the rest of the year can hide a problem until the first hot week it runs.
