Performed preventative cooling maintenance on outdoor Amana AC condenser unit. Changed indoor air filter. Swapped out of range capacitor. Checked the following: -Amperages on compressor and outdoor condenser fan motor. -Dual run start capacitor for the compressor and fan. -Contactor and proper voltage. -Refrigerant circuit for proper flow. -Thermostat functionality. -Proper air flow/temperature split from supply and return vents. System is cooling well at this time with a temp split of 23°.
