The overall performance of your refrigerating or air conditioning is based at the circumstance of the expansion valve. It controls the quantity of refrigerant that enters the evaporator coil to cool the device successfully. But when it starts failing, it can cause multiple problems.
When you recognize the symptoms of a deficient expansion valve, you can save yourself from expensive damage and lack of cooling comfort. If you need an expansion valve issue consultation, visit https://www.socool.sg/expansion-valve-replacement/ for professional replacement services provided to you.
Following are the Symptoms of a failing Expansion Valve:
1. Inconsistent Cooling
One of the most common issues is inconsistent cooling in your space. Moreover, since some regions of the room may feel warmer than others, this hinders the system from maintaining a steady temperature. This leads to inefficient cooling and is bound to discomfort your office or house. If you face these issues, consult experts at https://www.socool.sg/, which offers diagnostics and solutions to your expansion valve issues.
2. Ice Accumulation on Coils
An evaporator coil can experience freezing due to an expansion valve malfunction. If the valve does not balance properly, the refrigerant feeding to the coil will be useless. Lookout for the following:
- Ice Formation around the Vents: Ice building around the coils or vents indicates that the refrigerant isn’t flowing correctly.
- Reduced Performance: As the system’s coils become frozen, the system’s ability to cool the air is reduced, reducing the overall efficiency and comfort.
- Increased Water Damage: Excess water melting from ice can collect around the system, threatening severe water damage.
3. Reduced Airflow
A symptom that accompanies a faulty expansion valve is the reduction of the airflow. Since the valve is responsible for the amount of refrigerant the system receives while clockwise turning, it increases the flow into the system. Check the expansion valve to see if your AC and refrigerator cooling unit blows cool air but feels weak.
4. Increased Bills of Energy
If you have noticed increased energy bills recently, there may be a refrigerant flow problem. An issue with the flow can cause the unit to run perpetually, leading to the higher energy costs. It is best to address the issue promptly to avoid the unnecessary expenses.
5. Noises Out Of Order
There are some other cases where you may need to pay attention, such as strange hissing and gurgling sounds emitted from your air conditioning unit. These sounds may very well indicate that the expansion valve is not working correctly. Often, these sounds are triggered by the abnormal flow of refrigerant.
6. Insufficient Air Flow
The lack of proper airflow may also indicate an issue with the expansion valve. Whenever the valve cannot control the refrigerant flow, it may result in insufficient airflow. This is because the evaporator coil will have heat absorption and release limitations. It is wise to check the expansion valve for weak airflow.
7. Defective Compressor
An excess or insufficient amount of refrigerant gets to the evaporator coil. The evaporator coils may get damaged which may lead to compressor damage if the expansion valve does not work properly. If the refrigerant reaches the compressor and the system is in an abnormal state, the compressor would too. If the workstation has abnormal conditions, it may become too hot and burn out this critical component.
8. Expansion Valve Replacement
The above conditions indicate some immediate action. Many professionals guarantee restoration of expansion valve replacement and heating, ventilation, refrigeration, and air conditioning systems. A replacement can be made easily, and the damaged expansion valve can be installed without any issues.
