Troubleshooting Checklist: No Cooling

If you’re having trouble with your air conditioner or cooling system, you can always call our offices for help and service. However, here are a few simple suggestions to try before setting up a service appointment.

  • Check to make sure that the thermostat is set in the COOL position.
  • Make sure that the temperature setting on the thermostat is set LOWER than the current indoor temperature.
  • Ensure that there’s power to the air conditioner/condenser:
    • Check the circuit breakers in the electrical panel and make sure they are all in the ON position.
    • Check the outdoor unit “disconnect switch” to make sure it is in the ON position. The disconnect switch is located near the outdoor unit and is normally within a gray 8” box mounted to the house.
  • Is there any air coming out of your vents?
    • Always make sure you routinely change out your filters as directed to ensure peak performance.
    • In addition, check all return air grilles and registers to make sure they are not blocked by furniture and are open and blowing air.
