When does an expansion valve need to be replaced?
Unless the compressor failed internally, sending debris/burnt oil throughout the AC system, the expansion valve doesn’t require replacement.
How does the expansion valve in an air conditioner work?
This part also depressurizes the refrigerant until it becomes cold enough to cool down the warm air passing through. As you can see, the expansion valve plays a critical role in reducing the temperature in your home to a comfortable level, and the whole system can go haywire if just this one part malfunctions.
Can a broken expansion valve cause an air conditioner to make noise?
It’s not unusual for air conditioners to make noise when parts malfunction. As such, a broken expansion valve will cause your machine to make squealing, banging, or clanging noises that worsen over time.
Do you have to take frigin dash off to replace expansion valve?
You have to take the frigin dash off in order to replace it!!! So, since it appears that there is nothing internally wrong with the a/c, do I really need to replace the expansion valve? NO !!! you do not. There are ways to troubleshoot expansion valves, look on youtube.
Where is the expansion valve on an AC unit?
The AC expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Whenever there is an abundance of refrigerant, the core of the evaporator will get too cold and eventually freeze.
Unless the compressor failed internally, sending debris/burnt oil throughout the AC system, the expansion valve doesn’t require replacement.
Can a condenser and evaporator coil be replaced?
Well, it’s not always that easy. In some situations, replacing just the evaporator coil means it will “mismatch” your condenser (the outside unit). And if the condenser and evaporator mismatch in either age, SEER or refrigerant, you’re going to run into problems like:
How can you tell if your AC has a bad expansion valve?
Warm Air – The most recognizable symptom of a bad AC expansion valve is when you turn on your air conditioner and warm air starts blowing out of the vents. This would obviously mean that not enough refrigerant is making its way to the core of the evaporator.

What are the symptoms of a bad expansion valve?
Inconsistent Airflow – Sometimes a bad AC expansion valve will provide an inconsistent performance in its ability to regulate the flow of refrigerant throughout the system. If this were to occur, the air coming out of the vent may be too cold or too warm.

What happens when an expansion valve goes bad?
When the expansion valve fails or has any issues, it can cause problems with the functionality and performance of the AC system. Usually a bad or failing AC expansion valve or orifice tube will produce a few symptoms that can alert the driver of a potential issue.
How to replace the expansion valve on a refrigera?
1. DISCHARGE REFRIGERANT FROM REFRIGERA– 2. REMOVE BLOWER UNIT 3. REMOVE EVAPORATOR COVER (a) Remove 2 bolts for the liquid and suction tube. (b) Remove 8 screws and evaporator cover. the evaporator and expansion valve.
Can a bad expansion valve cause an AC compressor to run?
AC compressor constantly running. A constantly running compressor is another symptom of a possible problem with the AC expansion valve. If the AC expansion valve fails or sticks open, it will cause the compressor to pump refrigerant through the vehicle’s AC system, even when it may be undesirable for it to do so.
