Came out for a callback where the unit was leaking water. Discovered bad old condensate pump, recommended new one to customer and replaced with a new pro select condensate pump. Tied safety switch into the unit so that if ever the condensate pump over flows the unit will shut off. Tested pump for proper operation, unit and pump are both operating properly at this time.
