Your AC Appliance Won't Cool? 3 Signs Of A Defective Evaporator Coil

Posted on

The evaporator coil is vital to the air conditioner's cooling process. The evaporator coil has several components that aid its function. Understanding the parts and their responsibility in the cooling process will help you avoid many AC complications. Here are three top signs that probably the evaporator coil of your appliance is damaged and needs repairs. 

Warm Air Blows From Your AC Appliance's Vents

The evaporator coil is typically full of the evaporated refrigerant from contact with the warm air in the home. It absorbs all the heat from the air that blows over it. The air then returns to the room at a lower temperature. Therefore, when the evaporator coil of your appliance is working, the air that returns to the room from the vents should be cold. If the air returns while still warm, the part has failed. The problem could be something as simple as dirt covering the surface. The coating prevents air from blowing over the refrigerant effectively. A competent AC repair expert can assess your system to determine what needs cleaning or fixing to restore the function. 

The AC Won't Stay In Operation But Keeps Going Off 

Another indicator that you may need to have a technician check your evaporator unit is when the entire unit won't stay in operation but keeps going off frequently and doesn't cool the home as it should. The frequent cycling means that the system is working hard to try and remove heat from the house, but the evaporator is unable to absorb the heat. A technician will help determine the probable cause of the problem. If you ignore frequent cycling, a point comes when the system stops working altogether. It is best to speak to an AC repair expert and assess it before the unit stops working altogether. 

Leak Close to the Evaporator System

A leak close to the evaporator system also indicates the system is damaged. Often, leaks near the system's indoor part indicate a loss of refrigerant. The refrigerant is volatile, and its fumes are dangerous to inhale. A reduction in refrigerant levels compromises the efficiency of the AC appliance. It's advisable to have a competent technician assess and fix the leak immediately after the problem comes up.

The evaporator determines the efficiency at which your AC system operates. It is wise to speak to a competent AC repair technician about any issues with the appliance's evaporator coil for quick and effective repairs.
