Homes and businesses can help people find comfort on a hot summer day thanks to central air conditioning systems. The central air conditioning system is among the great examples of modern engineering as it provides the indoors with cooler temperatures. To make the central air operate smoothly, there are many components to the central air conditioning system that are made up of smaller parts. The central air conditioning relies on these parts in order to remove the warm air and push it outside, and among them is the expansion valve. Without this vital component, air conditioning would not be possible. We at Air Supply Heating & Air Conditioning would like to take the opportunity to share the basics of the expansion valve to help you better know your air conditioner.

AC Expansion Valve Function

Your air conditioner functions by funneling refrigerant throughout the system and transforming that refrigerant from a liquid to a gas and back again. Moving inside your home or business is the cool, liquid refrigerant as the heat is absorbed. With the heat absorption, the refrigerant then turns into a gas. The gaseous refrigerant moves to the outdoor portion of the unit to allow the absorbed heat being released outside. The cycle repeats after the release transforms the refrigerant back to a liquid form. After the gaseous refrigerant releases the heat from the air into the outdoors, the refrigerant is still too warm to absorb more heat once back inside. To play its part in the air conditioning process, this is where the expansion valve steps in. The expansion valve removes pressure from the refrigerant, which permits the refrigerant to cool rapidly in preparation for more heat absorption.

Bad Expansion Valve Symptoms

With a number of problems an air conditioner can experience can be associated with a malfunctioning expansion valve. Some of the common examples include:
1) Frozen coils. The refrigerant gets too cold and starts freezing everything in its path since the expansion valve is valve is responsible for depressurizing the refrigerant to cool it. Frost gushing from the vents, frozen coils, or ice forming on the appliance’s exterior all indicate that something is going wrong with the refrigerant, and the expansion valve, paired with other symptoms, indicates the valve isn’t doing its job.
2) A/C continually runs. Should the expansion valve malfunction, the refrigerant continues feeding into the compressor. The compressor continues running nonstop to deal with the gas as a result. Without shutting down between cycles to let the system rest, this keeps your air conditioner will run continuously.
3) Air conditioning makes unusual noises. It is not strange for the air conditioners to protest with odd sounds when parts malfunction. Worsening over time, the clanging, squealing, or banging noises emit due to a faulty expansion valve.
4) The air conditioning is not producing cool air.
