Hvac Expansion Valve Troubleshooting at Callum Winter-irving blog

Hvac Expansion Valve Troubleshooting. When it comes to a heating & cooling system, there are many parts that work together to keep our homes comfortable. Testing a thermal expansion valve (txv) can be done in just a few simple steps. If the superheat is well above 14° at the evaporator outlet, with the proper subcool and liquid pressure entering, then you have a failed closed (underfeeding valve). One of those critical components is the txv, or thermal. A bad thermostatic expansion valve (txv) can cause low superheat in an hvac system by allowing too much refrigerant to flow into the evaporator coil. Bryan gives a masterclass to kalos techs on why txv/tev valves are misdiagnosed, how to properly diagnose a failed txv, and how thermostatic expansion valves. The data includes indoor fan speed, coil temperatures, heat exchanger pressure, compressor speed, outdoor ambient.
