- Found faulty/failed thermostat for zone one/downstairs. - System currently draining properly and hasn’t retained water. - pulled common wire on zone board/ damper two…to finish diagnostics. - Checked filter/ 20x25x2 / clean / points correct direction - Checked all electrical components as well as refrigerant charge. - System currently functioning cooling properly, except for downstairs zone due thermostat needing to be replaced. Homeowner said he would replace his own thermostat. Instructed him that if he chooses to do this himself to turn off the main power in the attic to the indoor equipment so not blow any fuses or cause any other damage. - System cooling and draining functioning properly upon departure.
