Understanding Refrigerant Charging in HVAC Systems

At Lambert Heating & Air Conditioning, we often encounter issues related to improper refrigerant charging in HVAC systems. As a leading AC service company in Harrisburg, we believe it’s crucial for homeowners to understand the technical aspects of this important process.

What is Refrigerant Charging?

Refrigerant charging refers to the process of adding or removing refrigerant from an HVAC system to ensure it operates at peak efficiency. The correct amount of refrigerant is critical for optimal performance and energy efficiency.

Technical Aspects of Proper Charging

1. Superheat Method: This technique is used for fixed orifice systems and involves measuring the temperature difference between the evaporator coil outlet and the refrigerant’s saturation temperature.

2. Subcooling Method: Used for thermostatic expansion valve (TXV) systems, this method measures the temperature difference between the liquid line and the refrigerant’s condensing temperature.

3. Weigh-In Method: This precise approach involves evacuating the system and adding the exact amount of refrigerant specified by the manufacturer.

Consequences of Improper Charging

• Reduced cooling capacity
• Increased energy consumption
• Premature compressor failure
• Frozen evaporator coils
