An underperforming air conditioning or refrigeration system may be caused by a malfunctioning expansion valve. At EKG M & E Sdn Bhd, we offer professional Faulty Expansion Valve Detection services in Kuala Lumpur (KL) to diagnose irregular cooling, fluctuating pressures, or inefficient refrigerant flow. Whether for residential split units or large commercial HVAC systems, our experienced technicians provide fast, accurate detection and effective solutions to restore your system’s performance.
Precise Diagnostic Testing
We perform temperature and pressure readings at key points in the refrigeration cycle to detect improper expansion valve operation—whether stuck open, stuck closed, or cycling erratically.
Superheat and Subcooling Analysis
By measuring superheat and subcooling levels, we determine whether the expansion valve is delivering the correct amount of refrigerant to the evaporator coil.
System Performance Assessment
Inconsistent cooling, frost buildup, or low airflow often indicate TXV (Thermostatic Expansion Valve) malfunction. We analyze overall system behavior to pinpoint the issue.
Component Inspection and Testing
Our technicians inspect the expansion valve’s bulb, capillary tube, and sensing components for signs of wear, blockage, or loss of calibration.
Applicable to All HVAC and Refrigeration Systems
Suitable for wall-mounted split units, inverter systems, ducted air conditioners, centralized chillers, and commercial refrigeration setups.
Leak and Contamination Detection
We check for internal blockages, oil contamination, and refrigerant leaks that may affect valve performance and refrigerant flow control.
