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 ...

Regularly inspect the fan blades for dust buildup, cracks, or imbalance, and clean them gently to maintain airflow efficiency. Ensure mounting hardware is tight and secure. Check for unusual vibrations or noise during operation. Always disconnect power before performing maintenance for safety.

• Fan blade imbalance causing vibration or noise.
• Reduced airflow due to dirt buildup or blade damage.
• Cracked or bent blades affecting performance.
• Loose mounting leading to wobbling during operation.
