Common Questions and Answers

What part does the Lennox 25W27 Thermal Expansion Valve/TXV play in the equipment's workflow?

The thermal expansion valve/TXV regulates the flow of refrigerant into the evaporator so the HVAC system can maintain proper pressure, temperature and cooling efficiency during operation. Its precise internal construction matters because accurate metering protects the heating and cooling equipment from poor heat transfer, coil freeze-ups and uneven performance.

What are possible warning signs that the Lennox 25W27 Thermal Expansion Valve/TXV may be failing?

The thermal expansion valve/TXV may be failing if the heating and cooling unit shows reduced cooling capacity, erratic temperatures or pressure imbalances that can affect overall system performance. Physical signs can include frosting near the evaporator, while environmental signs may include unusual hissing, longer run times or inconsistent airflow conditions around the system.
