Lennox 39W70 Expansion Valve

The Lennox 39W70 Expansion Valve made of brass is an essential control element intended for Lennox HVAC systems. This key part is crucial in its contribution to the enhancement of the system's efficiency and cooling capacity. This checks the temperature of the air within the evaporator coil. Using this information it can control the amount of refrigerant allowed into the coil at a given time. This makes certain that the coil has the right amount of refrigerant to do the required work of heating up and therefore giving out high and improved cooling results.
