Condenser coil was extremely dirty causing lack of airflow to the outdoor unit, resulting in heightened refrigerant pressures. After washing the outdoor coil with water hose, pressures settled to acceptable levels for r22 (75/180). Airflow in the house is poor. Supply registers are crushed, haunting airflow even more. Compressor and fan motor on outdoor unit both sound very rough, but unit is now producing cool air. With age and condition of equipment I highly recommend replacing the system soon.
