York S1-363-90016-705 6-Tube Heat Exchanger

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Inspect the heat exchanger regularly for cracks, corrosion, soot buildup, or restricted airflow that may affect furnace efficiency and safety. Clean surrounding burner compartments and verify proper combustion during routine heating inspections. Periodically check for unusual odors or carbon monoxide concerns and disconnect power before servicing.

• Reduced heat transfer due to fouling.
• Refrigerant or pressure leakage at joints.
• Uneven heating or temperature fluctuations.
• Tube blockage or corrosion.
• Scaling inside tubes restricting flow.
• Loss of thermal efficiency over time.
