Several issues can cause an AC to stop working. Here are the most common:
Refrigerant Leaks: Low refrigerant levels due to leaks can prevent the AC from cooling effectively.
Frozen Coils: Dirty air filters or low refrigerant can cause coils to freeze, restricting airflow.
Clogged Filters: Dirty filters reduce airflow and strain the system.
Electrical Problems: Faulty wiring or tripped breakers can interrupt power to the unit.
Thermostat Malfunctions: Incorrect settings or broken thermostats can cause the AC to malfunction.
Drainage Issues: Clogged condensate drains can lead to water damage and stop the AC from working.
Regular maintenance can help prevent these issues.
