Common Evaporator Coil Repairs
The evaporator coil provides clean and fresh air. If it gets clogged, the air from the AC becomes dusty and dirty.
The evaporator coil is an integral part of the air conditioner. It provides cold air by absorbing and cooling down hot air. The coil must be clean and functional, essential for the AC unit. Various problems can occur with the evaporator coil, and it will need repairs.
Please keep reading about the most common evaporator coil repairs.
Dirty coil
The evaporator coil provides clean and fresh air. If it gets clogged, the air from the AC becomes dusty and dirty. This isn't just bad for the people and the environment but can also affect and damage other AC parts like condenser coils or compressors.
Keeping the evaporator coil clean is cost-efficient, and you won't need to replace AC parts. Keep in mind that the lifespan of the coil can be 6 to 30 years, but it needs cleaning every 10 to 15 years to prevent expensive fixes.
Frozen coil
Another common problem with the evaporator coil is ice accumulation on the outer tube. The AC and evaporator coil can't cool hot air if ice is in the tube. This occurs because the hot air can't be absorbed since the accumulated ice creates isolation. Furthermore, the AC won't work properly if something is blocking the airflow or the tube is damaged. This means one must clean dirt or debris from the outer tube to provide regular airflow.
Leaky air conditioner
The problem can usually be traced back to the refrigerant if the AC leaks. This affects the air conditioner unit's balance, making it work harder, eventually leading to more severe issues. The leaky refrigerants contain chemicals toxic to people and the environment. But besides this, the leak causes damage and corrosion to the air conditioner unit.
Faulty evaporator fan
When the fan isn't working correctly, the air won't reach the evaporator coil, which prevents it from cooling off. A working fan sends cool air through the ventilator and hot air to the coil to eliminate the heat. The AC can't provide cool air when the fan motor stops working completely.
Corrosion
One of the most common problems for the AC and the evaporator coil is corrosion. Apart from refrigerant leaks causing evaporator coil corrosion, this problem may occur in various situations. Corrosion can occur if the coil is too old, used for years without cleaning, or installed incorrectly.
Other issues
If AC provides warm air, it means there is accumulated ice in the outer tube of the evaporator coil.
The utility bills are higher than usual because the AC is working harder and with more pressure. A dirty coil is often the culprit.
Unusual noises coming from AC implies the refrigerant is leaky.
Maintain the evaporator coil
This integral part of the AC unit keeps the air cool. How well the evaporator coil works or whether it's repairable or replaceable will also depend on how old the device is and how often it is cleaned. If in need of a replacement, seek professional help.
