Repairs are short term solutions and we highly recommend upgrading. System serving the main floor has a major leak in circuit. We charged unit up and system is now cooling well. We do not warranty freon or can guarantee how long unit will cool properly. Also found a very worn and pitted contactor which will fail soon and cause a breakdown. Wire was already starting to melt off. Dual capacitor is below specs and can cause unit to fail and damage other electrical components. Customer has declined those repairs at this time. Basement system condensate pump is not pumping properly. Customer is trying to do repair himself. If he needs any help he will call us back. System is currently cooling properly. Current refrigerant pressures: TXV COIL -Low= 125 -High= 325 -Super heat= 18' -Subcool= 14'
