Potential Problems Your AC's Evaporator Coil Could Experience

Air conditioning is crucial in maintaining comfortable indoor temperatures, and they are especially valuable during the sweltering summer months. However, issues can arise within air conditioning systems, causing performance issues and discomfort. The evaporator coil is a critical component that transfers heat from the air and is essential for effective cooling. When this coil malfunctions, it can lead to numerous air conditioning problems.

Inadequate Maintenance Of The Evaporator Coils Can Cause A Failure

Overlooking maintenance can result in various problems, including evaporator coil failures. One frequent issue stemming from insufficient maintenance is a dirty air filter. Blocked air filters restrict airflow, causing the evaporator coil to freeze. Consequently, the coil may crack or rupture, resulting in expensive repairs.

Moreover, failing to clean the evaporator coil can lead to decreased efficiency and eventual failure. Accumulations of dust on the coil diminish its heat absorption capacity. This can cause the coil to overheat and ultimately fail. Scheduling regular maintenance appointments with a certified HVAC technician is crucial to maintaining your air conditioning system's performance.

A Minor Or Major Refrigerant Leak

Refrigerant is vital for the efficient functioning of an air conditioning system. It transfers heat to the external condenser unit. When refrigerant leaks occur, they can cause significant evaporator coil issues. As the refrigerant level decreases, the coil may lose pressure, preventing it from working correctly.

Unfortunately, homeowners may assume that it is normal for them to have to add more refrigerant to their AC systems at periodic intervals. However, this should not be the case, and if it is needed, it indicates a leak in the refrigerant lines that must be patched.

Performance Issues Due To Electrical Complications

The evaporator coil is integral to the air conditioning system's electrical network. Electrical issues can lead to coil failure. A common electrical problem associated with evaporator coil failure is a defective capacitor. The capacitor supplies the energy needed to start and maintain the compressor's operation. A malfunctioning capacitor can cause the compressor to malfunction, leading to evaporator coil failure.

Another electrical issue that can result in evaporator coil failure is a faulty contactor. This component connects the evaporator coil to the electrical system. A failed contactor can cause the evaporator coil to malfunction, leading to diminished cooling capacity and other issues. If you suspect an electrical problem with your AC system, it is crucial to contact a professional HVAC technician for prompt diagnosis and repair. Rapid repairs can limit the risk of further damage occurring to the AC system.
