Before Calling

Quick checks that can help the service call.

Do not take apart equipment. These simple checks help describe the issue and may reveal a basic setup problem.

  • Confirm the thermostat is set to cooling and the temperature is below room temperature
  • Check whether the air filter is extremely dirty or blocked
  • Look for ice on the indoor/outdoor lines or coil area and turn cooling off if frozen
  • Check whether the breaker has tripped once; do not keep resetting a breaker that trips again
  • Keep the outdoor unit clear of obvious airflow blockage and call if the unit is not starting
