Common Causes For An AC Breaking

Several common causes can lead to an air conditioner breaking down:

Lack of maintenance: Regular maintenance, such as cleaning filters, coils, and checking refrigerant levels, is crucial for the proper functioning of an AC unit.

Neglecting maintenance can cause various issues over time.

Dirty filters: Dirty or clogged filters restrict airflow, reducing the efficiency of the system and potentially causing the evaporator coil to freeze.

Refrigerant leaks: Refrigerant is essential for cooling the air.

If there's a leak in the system, the AC won't be able to cool properly, and the compressor might get damaged due to overheating.

Electrical issues: Faulty wiring, worn-out contactors, or capacitors can cause electrical problems, leading to the AC not turning on or not cooling properly.

Thermostat issues: A malfunctioning thermostat can cause the AC to cycle incorrectly or not turn on at all.

Frozen evaporator coils: This can occur due to restricted airflow, low refrigerant levels, or other issues, resulting in reduced cooling capacity or complete system failure.

Dirty condenser coils: Dirt and debris on the condenser coils can hinder heat transfer, leading to inefficient cooling and potential system failure.

Fan problems: Issues with the fan motor or blades can prevent proper airflow, resulting in poor cooling performance or system overheating.

Drainage problems: Clogged condensate drains can lead to water backup, causing damage to the AC system and surrounding areas.

Age of the unit: Like any mechanical system, air conditioners have a lifespan.

Older units are more prone to breakdowns due to wear and tear.

Regular maintenance, timely repairs, and addressing issues promptly can help prevent many of these common causes of AC breakdowns.
