Five months of hard running in Morristown heat

Your air conditioner works May through September here, with summer afternoons averaging 86°F. That is five straight months where the system runs long hours just to keep up, and every one of those hours puts wear on the same parts.

Hamblen County has also seen 59 damaging wind events and a few hail events over the past ten years, including hail over an inch across. Wind can knock the outdoor unit's fan out of balance or drive debris into the coil. A tune-up checks the coil, the refrigerant charge, and the electrical connections before a hot stretch finds the weak point for you.

5 months: May through September, your air conditioner is on duty
86°F: the average summer afternoon it cools against
3 hail events: in ten years, and hail bends the fins on outdoor coils
59 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 refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil, the blower motor, and the condensate drain for clogs. They also check the thermostat is calling for cooling correctly and look at electrical connections for wear. In Morristown, where the unit runs steady from May through September, a clean condenser coil and a clear condensate drain matter most, since both work hardest through those months.
How often does an air conditioner need maintenance?: Once a year, ideally in spring before the cooling season starts. That gives a technician time to catch a weak capacitor or a low refrigerant charge before the unit has to run through summer afternoons that average 86°F here. Waiting until the unit is already struggling means more strain on the compressor in the meantime.
Is AC maintenance worth it?: Yes. A yearly checkup catches small problems, a failing capacitor or a dirty coil, before they cause the compressor to work harder than it should or fail outright. Morristown's storm history includes 59 damaging wind events over the past ten years, and a maintenance visit is also a chance to check that the outdoor unit and its wiring came through weather like that undamaged. A contractor can look at the specific unit and say what condition it is in.
