A short cooling season, but the unit still sits outside all year

Ellsworth doesn't ask much of an air conditioner. Summer afternoons average 76°F, and cooling season here runs about a month. The compressor isn't working hard, and it isn't working long.

But the outdoor unit sits outside through everything else too. Hancock County has recorded 75 damaging wind events and 9 hail events over the past ten years, with hail as large as 1.75 inches. A tune-up is when a contractor checks the cabinet and fins for that kind of damage, along with the wiring and connections, before the unit is asked to start up again.

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 charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain line is one of the most common reasons an AC stops cooling. They also check the thermostat and confirm the system cycles on and off the way it should. The filter gets checked too, since a dirty filter restricts airflow across the coil.
How often does an air conditioner need maintenance?
Once a year is standard for a home air conditioner. A checkup before the cooling season starts catches problems while there's still time to fix them without losing cooling on a hot day. Waiting until the unit is already running hard means a small issue, like a low refrigerant charge or a weak capacitor, gets found only after it causes a breakdown.
Is AC maintenance worth it?
Yes, because most AC breakdowns trace back to something a checkup would have caught, like a failing capacitor or a coil coated in dirt. Ellsworth also sees real storm activity, with 75 damaging wind events and hail up to 1.75 inches over the past ten years, and an outdoor condenser sitting exposed to that weather benefits from someone checking the coil fins and refrigerant lines for damage. A yearly visit costs far less than a system that fails in the middle of a hot afternoon.
