Five months of hard running in Columbia heat
Your air conditioner runs May through September here, five months a year, with summer afternoons averaging 91°F. That is the load it carries every cooling season, month after month with little break.
A tune-up checks the parts that carry that load. The refrigerant charge, the condenser coil, the electrical connections that keep the compressor starting. Finding a weak connection or a dirty coil before the next stretch of hot afternoons means the unit is not running on a part that is already failing.

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 level, cleans the outdoor coil, and tests the capacitor and contactor in the condenser. 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 for any signs of wear. Every part gets checked because a weak capacitor or a clogged drain can take the system down just as fast as a low refrigerant charge.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts. Homes here run the AC from May through September, so having it checked in spring means it's ready before the first hot stretch hits. Summer afternoons here average 91°F, and that kind of heat means the system runs long hours with no room for a weak part to go unnoticed.
- Is AC maintenance worth it?
- Yes, because it catches small problems before they turn into a breakdown in the middle of summer. A technician checking refrigerant level and electrical connections once a year finds a failing capacitor or a dirty coil while it's still cheap to fix. This area also sees hail and high wind most years, so a yearly check is a good time to look over the outdoor unit for any damage those storms may have caused.
