The evaporator plays a critical role in your air conditioner's operations. Problems that affect the evaporator coil affect the efficiency of the AC. Read on for an overview of such problems so that you understand why you should have a technician inspect and repair your evaporator coil.
Your AC has a blower that blows inside (warm) air over the evaporator coil. The evaporator coil has tubes that contain cold refrigerant in its liquid state. As the warm air blows over the refrigerant coil, the refrigerant absorbs the heat and cools your home.
If your evaporator coil leaks a significant volume of refrigerant, the remaining refrigerant won't absorb an adequate amount of heat. As a result, your AC efficiency will drop, and your home won't cool properly. Reduced cooling efficiency causes the AC to overwork. The increased run time increases your AC's risk of damage, so expect to deal with frequent breakdowns.
Reduced cooling is not the only effect of a refrigerant leak. The refrigerant is a poisonous chemical that no one should breathe, but that is what will happen if the refrigerant leaks. Respiratory and skin problems may follow. The refrigerant is also harmful to the environment; it contributes to the depletion of the ozone layer.
Here are some of the problems that can cause refrigerant leaks from the evaporator coil:
● Corrosion on the coils — the presence of acidic compounds in the air, such as household cleaners, increases the risk of corrosion.
● Wear and tear — an old coil is likely to suffer damage since everything eventually ages.
● Vibrations — the presence of vibrations in the vicinity of the coils, such as earth-moving equipment, increases the risk of damage to the coils.
● Accidental damage — a tree fall, for example, can damage the coils and trigger refrigerant leaks.
Guard against the above problems to reduce the risk of a refrigerant leak.
