  • Check your air filter and replace it if it’s dirty and clogged
  • Turn the fan setting to ‘On’ to run continuously
  • Monitor the thawing to make sure your condensate pan and condensate line don’t overflow or become clogged causing a water leak

This process can take up to 24 hours to complete but make sure your system is completely thawed and dried before you turn your AC on at the thermostat and put your fan setting back to ‘Auto’. When you turn your system back on, you want to monitor it for the next few days to ensure your system is cooling properly. If your indoor evaporator coil starts to freeze up again.
