In Charleston, Columbia and Greenville, an air conditioner has two jobs: drop the temperature and pull moisture out of the air. When it is low on refrigerant, undersized, or the coil is dirty, it may still move air but it stops doing the second job. The house reads 76 on the thermostat and feels like 82. That is not your imagination, and it is not the thermostat's fault.
A clogged filter starving the coil of airflow. A frozen evaporator coil that has turned into a block of ice. A failed capacitor so the outdoor fan or compressor will not start. A refrigerant leak that has slowly starved the system. A dirty outdoor coil that cannot reject heat on a 95-degree day. A stuck contactor. A thermostat set to 'fan on' instead of 'auto', which blows moisture back into the house between cycles.
Replace the filter. Set the fan to auto. Make sure the outdoor unit is running and the coil is not caked in dirt or pollen. Check the breaker. If you see ice anywhere, turn the system off so it can thaw. Anything past that requires gauges and a meter.
If the vents are blowing warm, ice is forming, the breaker keeps tripping or the house will not drop below 78, call for AC repair. We diagnose most not-cooling calls in under an hour and carry the parts to fix them the same visit.
