Customer had a major leak in home over the weekend from master bedroom hydro air handler causing damage to master bathroom, first floor kitchen, and basement ceiling, Sheetrock, insulation soaked, went to attic at air handler and found emergency pan completely full of water, emergency switch failed causing unit to not shut off when water was detected in pan, all thermostat wires going to master thermostat, boiler and condenser all under water, is most likely going to need new control board for furnace, emergency switch, new hot water coil for air handler, removal of water from emergency pan, system is going to need to be drained down to make repair and will need to be filled and purged with the addition of adding antifreeze to prevent systems from freezing over, and then system can be tested, air handler insulation is also soaked from hot water coil leaking, hot water coil more than likely froze over and burst when it was cold, customer had shut water off at boiler for that zone.
