Is Your Air Conditioner & Heat Pump Ready for Winter?

In winter, frost buildup on the outdoor unit of your air conditioner can significantly affect its efficiency and overall performance. To address this, LG’s HVAC systems are equipped with an automatic defrost function, which plays a vital role in preventing frost accumulation. This feature ensures that the system maintains optimal operation, allowing it to continue running efficiently even during cold weather conditions. By automatically activating defrost cycles as needed, it safeguards the system from performance issues and reduces the risk of energy waste, ultimately enhancing the reliability and longevity of your HVAC equipment.

LG air conditioners feature an automatic defrost system that relies on sensors to monitor the temperature of the outdoor unit. When these sensors detect a temperature drop to a point where frost formation is likely, the system initiates the defrost cycle automatically. During this cycle, the refrigerant flow is reversed, directing warm refrigerant through the coils to efficiently melt any accumulated frost. Once the frost is eliminated, the system seamlessly returns to normal operation, maintaining optimal performance and efficiency.

STEP 1: Temperature Monitoring
The sensors in the LG air conditioners continuously monitor the temperature of the outdoor unit.

STEP 2: Temperature Detection
When the sensors detect that the temperature has dropped to a level where frost is likely to form, they trigger the defrost cycle.
