Like all other electrical appliances, the air conditioner experiences wear and tear over time. Regular maintenance is important to keep them functioning. Knowing the causes of air conditioner failure can help you make informed decisions, and more importantly, prevent them from happening.

So, What Causes Air Conditioner Failure?

Low Refrigerant

Refrigerant is one of the key components of an air conditioner as it removes the heat and humidity from the air in your home or office and keeps the room cool and comfortable. If there are leaks on the refrigerant lines, there won’t be enough refrigerant in the cooling system to cool the air effectively. However, an air conditioner won’t stop working suddenly. It will show some warning signs, and low cooling or not enough cooling is one of the signs that indicate there’s something wrong. You might have ignored the signs. Just replacing the refrigerant alone won’t help to resolve this issue. An HVAC technician needs to find the leaks and repair the holes in the lines, that’s time-consuming and expensive, especially when there are multiple leaks.

Fan Problems

Every air conditioner contains a fan that blows indoor air over the unit’s evaporator coil to cool the air. There’s another fan that blows the air over the outdoor unit’s condenser to remove the heat outside the building. If either of the fans stops working, it won’t be able to cool the air efficiently. It might be due to lack of lubrication, faulty motor, too much dirt and debris, and worn belts. When this problem is neglected, it can cause compress failure, resulting in air conditioner failure.

Frozen Evaporator Coil

Every air conditioner contains an evaporator coil that is filled with refrigerant, and it is responsible for absorbing heat from the air like a sponge. The coils require warm air to work properly. When the airflow is obstructed, and the evaporator coil gets too cold, a layer of ice can build up on the outside and affects the quality of cooling.

Dirty Condenser Coil

The condenser coil won’t work efficiently, if there is a lot of dirt, grime, and dust. When it happens, the unit has to work harder to cool the room, resulting in increased wear and tear on the system. When not addressed, it can lead to system failure.
