What we did
A malfunctioning TXV called for immediate attention at this Nicholasville job in July. The TXV, or thermostatic expansion valve, controls how much refrigerant flows into the evaporator coil, and when it is not working correctly, the whole system's performance suffers.
Our technician Ivan oversaw the entire repair. We replaced the TXV along with the reversing valves to restore proper function to the system. Reversing valves are what allow a heat pump to switch between heating and cooling modes, so they are a key part of how the system operates. With both components replaced, the system is set up to operate efficiently again.
In July, central Kentucky heat and humidity put cooling systems under steady load, and that is exactly when a valve problem becomes hard to ignore. Replacing these components restores the reliability the system needs to keep up. Valve work like this takes care and experience, because it involves the refrigerant circuit at the core of the system. Having one technician handle the entire process from start to finish helps make sure the repair is done correctly. If your system is not heating or cooling the way it should, valve problems are one of the things we check.
