Air conditioning is the largest single consumer of electricity in your home this summer, accounting for as much as half of your entire energy bill. A thermal expansion valve is a feature that helps keep these costs down.
What is a thermal expansion valve?
This type of valve measures refrigerant flow through the system, automatically adjusting as cooling conditions change. When cooling demand is high, the thermal expansion valve opens wide. Likewise, when demand is low, the valve closes partway to reduce refrigerant flow.
The valve senses cooling load by measuring the refrigerant’s temperature when it exits the indoor coil. It senses that temperature increases indicate higher cooling load. In short, the thermal expansion valve creates a more efficient air conditioner.
