Common Solutions for AC Not Cooling

Resetting the AC Unit

  1. Turn Off the AC Unit: Start by turning off your AC unit to prevent any further damage. This step is crucial to ensure your safety and the longevity of your system.
  2. Turn Off the Breakers for 5 Minutes: Find your electrical panel and turn off both breakers for the AC unit, indoor and outdoor unit. This reset can help clear minor faults and restore normal operation. Wait for about 5 minutes before turning them back on. The outdoor unit should be turned on before the indoor unit.
  3. Restart the AC: Turn the breakers back on and restart your AC. First, turn on the condensing unit and wait at least 3 minutes, then turn on the air handler. Observe the outdoor unit’s fan. It should be blowing out air hotter than the surrounding temperature. If it isn’t, it’s time to turn off the unit and call for professional service.

Further Troubleshooting Steps

  1. Flow Switch Check: The flow switch monitors water flow within your AC system. Check for any water around the flow switch, which could indicate a problem requiring professional attention.
  2. Check the Filter and Coil: Remove the filter and inspect the coil for any signs of freezing (ice). A frozen coil will affect your AC’s cooling capabilities. Ensure the filter is clean and the coil is not obstructed.
  3. Airflow Check: Place your hand on the AC grille to feel if the air is being blown out. Poor airflow can be a sign of various issues, from clogged filters to more serious mechanical or duct problems.
  4. Thermostat Battery Check: Ensure your thermostat has working batteries. Sometimes, a simple battery replacement can resolve the issue if your thermostat isn’t communicating properly with your AC unit.
