How do I know if my expansion valve is clogged?
One common symptom of a stuck expansion valve is when the air conditioning unit starts to run continuously, even when the car isn't being driven. This usually indicates that there is something blocking the flow of refrigerant which is causing the expansion valve to remain open.
Can you clean expansion valve?
It is very difficult to determine if a Thermostat Expansion Valve is clean. The only way to be sure the valve is clean is to put it back into operation and run a system performance test. If there is any malfunction, the unit must be disassembled again to change the valve.
What happens if expansion valve is stuck closed?
If the expansion valve is stuck open or clogged, the AC system will not cool properly. A clogged valve will lead to too little refrigerant, increasing the pressure in the system and causing the AC compressor to overheat.

What happens if expansion valve fails?
Whenever there is a faulty expansion valve, there will be fluctuations in its ability to control refrigerant flow in the unit. If this happens, the air from the vents will be too cold or warm. The air will constantly shift back and forth between various temperatures at different times.
What are troubles that comes in the expansion valve?
Problem. As the expansion valve operates under high pressures and is temperature sensitive, improper working conditions, as well as impurities inside the loop, can cause its deregulation and malfunction. If the expansion valve is stuck open or clogged, the AC system won't cool properly.
How much does it cost to replace expansion valve?
A TXV expansion valve manages the amount of liquid refrigerant flowing through the air conditioning system, so if it goes bad, you'll need to replace it to keep your AC functioning properly. Expect to pay an average of $400 to get the job done, but it may cost as little as $200 or as much as $700.
What is the Expansion Valve (Orifice Tube) all about?
The air conditioning system in your vehicle depends on the refrigerant that circulates in the A/C system. In particular, the evaporator core inside the passenger compartment requires a specific, metered amount of refrigerant in order to efficiently cool the interior.
Keep in mind
Air conditioning work needs to be completed by a trained and licensed professional in nearly all circumstances because refrigerants are regulated substances.
Our recommendation
Whenever air conditioning repairs or refrigerant recharges are performed, have the expansion valve inspected for proper operation. If the expansion valve is not opening or closing properly, you may need one of our expert technicians to replace the expansion valve or orifice tube.
How important is this service?
Air conditioning is a comfort item in a vehicle, not a safety issue. However, the air conditioning also removes moisture in the air for the defrost setting to clear your windows. If the air conditioning is not working properly, your vision may be impaired in humid or very cold weather.
