An air conditioner expansion valve is a crucial component in the cooling process of an air conditioning system. It regulates the refrigerant flow between the evaporator and the compressor and the refrigerant pressure in your AC, allowing the air conditioner to cool the air in your The Colony, TX home or building. However, a faulty expansion valve can cause several issues with your AC system, including decreased cooling efficiency, increased energy consumption, and even complete system failure. There are several signs that you point to a damaged evaporator valve, as we shall explain below. If you notice either of the signs, it is important to call a professional for an AC repair as soon as possible to prevent further damage to your system.
Higher Energy Utility Bills
A faulty AC expansion valve can result in an increase in cooling energy bills for several reasons. When the expansion valve is not functioning properly, it can restrict the refrigerant flow to the evaporator coil. This means that the evaporator coil needs to receive the proper amount of refrigerant to absorb heat from the air. As a result, the air conditioner will have to work harder to cool the air, increasing the unit’s energy consumption. This also exposes the unit to wear and tear, prompting a need for an AC repair. Additionally, the evaporator coil may not reach the desired temperature, causing the compressor to run longer to try to reach it, which can also result in increased energy consumption.
Additionally, if the valve gets blocked and doesn’t allow refrigerant to flow, it will cause the compressor to keep running and not shut off. It will be trying to pump refrigerant that is not there, which will cause overconsumption of energy. Since the air conditioner cannot cool the air efficiently, it may also result in the unit running for longer periods, which can increase energy consumption and bills.
A faulty AC expansion valve can lead to decreased cooling efficiency, increased energy consumption, and prolonged operation time, resulting in higher cooling energy bills. Hence, if the cooling bills have been increasing lately, you should have an AC repair technician take a closer look. This is because the AC’s expansion valve may be faulty.
Inconsistent Airflow Via Vents
The other sign that the expansion valve may be faulty and requires the attention of an AC repair technician in The Colony, TX is inconsistent airflow. As mentioned above, the evaporator valve is a critical component regulating refrigerant flow into the evaporator coil. The evaporator coil is responsible for absorbing heat from the air, circulating through the vents to cool the space.
When the expansion valve is not functioning properly, it can restrict the refrigerant flow to the evaporator coil. This can lead to several issues, including inconsistent airflow through the vents. If the evaporator coils don’t receive the proper amount of refrigerant, they will not be able to absorb heat, causing the air conditioner to struggle to cool your home efficiently. As a result, the air coming out of the vents may be less cool or have a different temperature consistency than it should. This needs to be checked by an AC repair technician.
Another way that a faulty expansion valve can result in inconsistent airflow is if the valve is blocked, preventing refrigerant from flowing at all. This can cause the compressor to keep running and not shut off, leading to a lack of cool air coming through the vents. This can also cause the evaporator coils to freeze, blocking the airflow through the vents. Therefore, call an Ac repair technician whenever you notice an inconsistent airflow from the air vents.
When the AC Unit Is Performing Poorly
A malfunctioning expansion valve may cause your air conditioner’s poor performance during hot weather. This component plays a crucial role in regulating the flow of refrigerant, and when it’s not working correctly, it can greatly impact the performance of your entire AC system. The unit may struggle to reach the desired temperature or blow warm air, depending on the severity of the issue with the valve. If you have been experiencing issues with your air conditioner’s performance, it may be a sign that the expansion valve is blocked or damaged. This can be a serious problem that a professional AC repair technician must address to keep the system running properly.
Air Conditioner Blows Warm Air
When an air conditioner unit is blowing warm air instead of cold, it can be caused by various factors. One possible reason is a malfunctioning expansion valve. The expansion valve is a critical component that regulates refrigerant flow to the evaporator coil, which is responsible for absorbing heat from the air. If the valve is not working properly, it can restrict refrigerant flow and lead to poor cooling performance.
Different issues can cause a defective expansion valve, such as leaking valves or low refrigerant levels. If you suspect that your expansion valve is malfunctioning, it is important to pay attention to the operating pressure of your AC unit. If the gauge readings are below normal, it is a sign of a problem that a professional AC repair technician in The Colony, TX should address.
Low refrigerant levels can also cause warm air to blow from the vents instead of cool air. Refrigerant is responsible for absorbing heat from the air, and when there is not enough of it, the evaporator coil will not be able to cool the air properly. This issue is usually resolved by adding additional refrigerant to the AC unit, but it is a task that a trained AC repair technician should only handle.
Have you noticed either of the signs above? That could mean a problem with the air conditioning unit, and it may have a faulty expansion valve. If you have noticed either, contact us at One Hour Air Conditioning & Heating of Dallas for a closer look.
