Went for a service call today. Changed the filter. Temp split between the supply and return duct passed. Evaporator coil has an excessive amount of rust and bacterial growth. Outside system is clean. Coil has some rust on it. Contactor has no burn marks. Control board has some burn marks. Condenser coil is rusted. Compressor and fan motor amperage passed. Capacitor failed as well. AC is up and running upon completion. Thank you for choosing LBA services!
