Arrived to home Set thermostat to cool Checked unit Found no clean out installed and hard plug in drain line (unable to clear with water or CO2 without clean out) Cleaned condenser coil System within MFG specs at this time Installed clean out and cleared drain line Due to drain not draining and vent being higher than system pan there is a potential for foreign growth inside unit. We will be able to assess further this fall during the fall maintenance.
