An air conditioner running continuously without producing chilled air is usually affected by one of several common mechanical failures. First, a severely dirty, clogged air filter restricts airflow, causing evaporator coils to freeze into solid ice. Second, low refrigerant levels from a hidden leak prevent the system from absorbing heat. Third, a dirty outdoor condenser coil stops heat dissipation. Fourth, a broken compressor capacitor prevents the compressor from pumping refrigerant. Verification: Hold your hand up to supply vents to check for chilled airflow and inspect the indoor air filter.
