There are a variety of different components, mechanisms, and materials that comprise your Avon, OH air conditioning system. While you may be familiar with the indoor unit, which comprises the evaporator coil and air handler, and the outdoor unit, which comprises the condenser coil and compressor, you may be less familiar with an equally important, but largely overlooked device known as the expansion valve. This relatively small device is incredibly important to the effectiveness and efficiency of your air conditioner, and the refrigerant cycle cannot work without it. We’d like to explain the basics of what the expansion valve is and what it does, so that you can stay informed about the inner workings of your home cooling system.

- What it is: The expansion valve is a metered orifice that controls the flow of liquid refrigerant. Refrigerant enters the input and is restricted by an aperture, whose tension and diameter is adjusted according to the specific needs of your cooling system. It is a relatively simple device, although it must be calibrated according to the pressure conditions of the rest of the system.
- What it does: The expansion valve is located between the condenser coils and the evaporator coils. While the condenser turns the hot gas refrigerant into a liquid, this liquid still contains a lot of pressure. In order to cool the air extracted from your home, the evaporator needs a low-pressure liquid, and this is exactly what the expansion valve does. By metering and controlling the flow of refrigerant, it creates a low-pressure liquid that also decreases its temperature.
- Why it’s important: Quite simply, you wouldn’t have any cool air without the expansion valve. The evaporator coil cannot remove the pressure (and temperature) from the liquid refrigerant that emerges from your condenser coil. The expansion valve is thus a necessary component designed to create cool, liquid refrigerant.
We hope you found this brief guide helpful. If you feel warm air blowing through your ductwork, or think that your AC is under-performing, your expansion valve may be faulty. Call Pompeii’s Plumbing & Heating today for excellent Avon, OH air conditioning services!
