Lennox 14W94 Outdoor Thermal Expansion Valve

The Lennox 14W94 Outdoor Thermal Expansion Valve is an essentialcomponent of the Lennox air conditioning system. It has the function of regulating the CF and having the highest operation of the system. This valve is used for the change of temperature in the evaporator coil, the part that is expected to absorb heat from your home. E time the temperature drops the valve leads to the refrigerant expanding and allowing more of it through to take more heat up. On the other hand when the temperature increases, it cooks the valve in a way that narrows and reduces the flow of the refrigerant thus avoiding over-cooling.
