Went for a maintenance call today. Both system are passing for static pressure. Temp split passes for both system. Both evaporator coil have rust forming. As well upstairs unit txv has corrosion building. Did notify customer about concerns on coils.Upstairs capacitor outside is at max. Main floor capacitor is failing. Both need to be replaced. Amperage pass for both system. Did clean both condenser unit outside. No wear and tear on wires. Main floor refrigerant passes for specifications. Upstairs fluctuates on charge. Coil is undersized for upstairs. Did adjust blower speeds and charge is within range. System is up and running before leaving. Thank you for choosing LBA services-Johann
