Every component of an air conditioner is important. However, they all have different functions. During the summer season, an air conditioner that is properly maintained will properly cool your Flower Mound, TX home to ensure that it is comfortable. Normally, an air conditioner uses a chemical coolant that changes in state between gas and liquid to dehumidify and cool your home. An expansion valve plays a critical role in this process. However, sometimes, this critical component of your air conditioner malfunctions. Knowing how to establish that the expansion valve has malfunctioned is critical so you can call an AC repair technician. How quickly the AC is repaired determines how fast you can return to comfort. What are the common signs that the expansion valve is faulty? Below are some signs to watch out for and how a professional deals with them.
Common Signs That the Expansion Valve Is Faulty
Air Conditioner Is Constantly Running
If the AC does not turn off at the temperature setting, there is likely a problem with the temperature sensor or the expansion valve. You should have an AC repair technician in Flower Mound, TX check the system to determine the underlying problem. The expansion valve, also known as the thermal expansion valve, is a device that regulates the flow of refrigerant into the evaporator coil. It works by opening or closing based on the temperature of the refrigerant, allowing the right amount of refrigerant to enter the evaporator coil to cool the air. If the expansion valve is faulty or broken, it can cause the AC to malfunction, leading to issues with temperature detection.
If you are experiencing problems with your AC not turning off at the temperature setting, you must contact a professional AC repair technician for help. An experienced technician can diagnose the issue and repair or replace any faulty parts, ensuring that your AC works properly. They can also perform regular maintenance and cleaning, which will extend the lifespan of your AC and improve its performance.
The Air Conditioning Unit Has Frozen Coils
The expansion valve is an integral part of an air conditioning system. Its main function is to depressurize the refrigerant, which is responsible for cooling the air inside the building. However, when this process is disrupted or cannot occur properly, it can lead to several problems that need AC repair, one of which is frozen coils. Frozen coils appear when the refrigerant gets too cold due to the expansion valve not functioning properly. The refrigerant is supposed to flow through the coils and absorb heat, but it can freeze and build up ice on the coils when it cannot do so.
This can not only affect the performance of the AC but also can cause damage to the unit, which can lead to costly repairs. When you notice that your AC coils are frozen, the expansion valve is not doing its job as it should. The problem should be taken seriously, as it can lead to more significant issues if addressed promptly. It’s strongly recommended that you refrain from attempting to fix issues with refrigerant levels on your own. Handling refrigerant can be dangerous, and it is essential that only trained AC repair technicians perform such work.
The AC Compressor Doesn’t Turn Off
A properly functioning expansion valve is crucial to operating an air conditioning system. It’s the component responsible for regulating refrigerant flow into the evaporator coil, allowing the right amount of refrigerant to enter and cool the air inside the building. However, if the expansion valve fails to shut off properly, it can lead to several problems that require the attention of an AC repair professional.
One of the most obvious symptoms of a malfunctioning expansion valve is that the AC will operate continuously without turning off. The refrigerant will continue to feed into the compressor, causing it to run nonstop. This can lead to the compressor wearing out faster, which may require repairs or replacement. Additionally, the internal temperature of your house may be too low for comfort and will cause high energy bills.
Compared to replacing a compressor, it is cheaper to have an AC repair technician in Flower Mound, TX replace the expansion valve. Hence, routine maintenance is the best way to protect the compressor. While it may be tempting to put off repairs, fixing the expansion valve sooner rather than later can help save money in the long run. It’s recommended to schedule an air conditioning repair service as soon as possible when this problem occurs, to avoid bigger issues and extra costs.
Odd Noises When the AC Is Running
The other telltale sign of a malfunctioning expansion valve is unusual noises from your air conditioning unit. These noises can include clanging, squealing, or banging, and may worsen over time. These sounds indicate that your expansion valve may be faulty if you notice these sounds. Act quickly; the longer you wait, the more severe the issue becomes and the costlier the repair may be. But fixing the expansion valve can be relatively affordable if you catch it early.
Therefore, if your AC starts producing odd noises, it’s best to reach out to a professional AC repair technician for help as soon as possible. In summary, Unusual noises like whistling from your air conditioning unit indicate that the expansion valve may be faulty. Acting quickly is recommended as this can prevent further damage, and the fixing is relatively affordable. An AC repair pro can diagnose the issue and replace faulty parts.
