What are some common problems with Goodman air conditioners? Common problems include evaporator coil refrigerant leaks due to formicary corrosion, especially in older copper coils before 2017, causing loss of cooling and need for coil replacement. Another common issue is capacitor failure, like all brands, causing compressor or fan not to start. Contactor failure and low refrigerant charge due to leaks at brazed joints. Some entry level models have loud operation due to single stage compressor and PSC fan motor. Drain line clogs causing water leaks. Sensor failures and control board issues in high efficiency variable speed models. Like other brands, Goodman can have compressor failure if airflow restricted by dirty filter or undersized ducts causing high static pressure. Some users report poor brazing quality leading to leaks if installer not careful. However many problems stem from poor installation, not manufacturing, such as incorrect Manual J sizing causing short cycling, improper refrigerant charge, and inadequate ductwork. Regular maintenance, filter changes, annual service, and proper installation by licensed contractor reduce common problems. Goodman warranty covers parts but not labor.
