What is a TXV valve on an air conditioner, and how does it affect performance? A thermostatic expansion valve (TXV) affects the performance of the cooling system by ensuring it runs as energy-efficiently as possible. If your system struggles to maintain a cool atmosphere, technicians offering HVAC services in Grapevine, TX will investigate the TXV’s performance and other aspects of the system.
What Does an Air Conditioner’s TXV Do?
What is a TXV valve on an air conditioner and how does it work? It manages the speed of refrigerant flow control into the evaporator coils of the central air cooling system.
The TXV system operation regulates the amount of refrigerant flowing through the system, allowing it to maintain appropriate pressure. This balance allows the air conditioner to run in an energy-efficient manner.
Although the TXV is a valuable component, its only job is to manage refrigerant flow. Don’t assume you can adjust the TXV and affect other aspects of the cooling system’s performance.
How Do I Recognize Signs of TXV Failure in My Home at Grapevine, TX?
Temperatures throughout spring, summer and autumn in the Grapevine, TX, region can be high, causing you to run your air conditioner regularly. You might notice higher-than-expected power bills when the air conditioner is not running efficiently during these times. If your AC cooling efficiency is lower than expected, a failing valve could be to blame.
Because the air conditioning refrigerant helps to reduce humidity levels in the home, you might also notice uncomfortable mugginess if the TXV is failing.
Grapevine, TX has a humid subtropical climate. Outdoor humidity levels can be high throughout the year in northeast Texas, meaning you might run your air conditioner more frequently. Summer humidity can be especially uncomfortable in Grapevine, TX so you might notice problems with the TXV more often during the hottest part of the year.
Will a Broken TXV Cause an Air Conditioning Refrigerant Leak?
What is a TXV valve on an air conditioner and can it cause a refrigerant leak if it fails? The diaphragm in the TXV could rupture or break down, creating a gap that allows refrigerant to leak. If the air conditioning system loses all its refrigerant, it will not be able to cool the home.
Because the TXV puts the refrigerant under pressure, the valve and its diaphragm are under significant stress. Even slight flaws in the TXV can break down faster because of the high levels of pressure in the cooling system.
You’ll need to call a professional cooling system technician to replace the refrigerant in your system. Grapevine, TX, building code regulations follow federal regulations for air conditioning refrigerants. Such regulations only allow certified HVAC technicians to put new refrigerant in a system.
Should I Work on the TXV Myself?
What is a TXV valve on an air conditioner and can you fix this component yourself? You should not try to repair or replace this valve as a DIY job.
Cooling system technicians have the equipment and experience to diagnose a faulty TXV. Technicians will conduct tests to measure the valve’s performance. They can also use an infrared scanner to identify areas that are leaking.
Technicians can replace the TXV with a minimal loss of refrigerant. If you try to fix this valve yourself, you could risk losing all the refrigerant in the system. You’d then have to call for help from technicians to replace the refrigerant in the system, so it’s smarter to call for help from the start.
The cost to replace a TXV valve typically ranges from a few hundred dollars to a few thousand dollars. However, due to the importance of this component to the cooling system, attempting to save money with DIY work is a dangerous idea. Having a professional technician work on the valve ensures it functions properly with your cooling system and maximizes the air conditioner’s longevity.
