How much does it cost to replace an AC expansion valve?

Usually, replacing your car’s A/C expansion valve will cost you around $150 to $350. The valve itself will set you back between $50 to $150 in most cases while the labor will run about $100 to $200, so it’s important to get a couple quotes first.

When should I replace my AC expansion valve?

How Long Does an Expansion Valve (Orifice Tube) Last?

If your expansion valve is cool and frosty, yet the air conditioning doesn’t seem to be blowing cold air out, there’s a good chance the valve needs to be replaced.
As a more basic symptom, it may be that cool air is blowing out but not cold enough.

Can you fix an AC expansion valve?

Replacing an expansion valve requires special equipment and there are a number of laws regarding handling refrigerants. So it is strongly recommended that you engage a professional to do this job. But if you want to tackle this job yourself, there may be ways to get help with the heavy equipment.

Why expansion valve is bad?

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. This will put an additional strain on the compressor and associated AC components, making them more susceptible to premature failure.

What happens when an AC expansion valve goes bad?

How much does it cost to replace an expansion valve?

But on average, car owners pay somewhere between $240 and $330 in most cases to do AC expansion valve replacement. That includes parts, which will run you right around $100, and labor, which will cost about twice that.

Do you need to replace expansion valve when replacing compressor?

You are supposed to replace the expansion valve and dryer with a new compressor because in cases of the compressor itself E36 M3ting the bed, the system will be full of trash, this is not your case by the sounds of it.

What happens when expansion valve sticks open?

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.

How does an expansion valve work?

An expansion valve, also called a TVX valve, regulates the flow of refrigerant inside of a cooling system . It uses a sensing bulb or disc that opens or closes the diaphragm to allow the refrigerant to pass through. If your air conditioner isn’t cooling your house or car properly, it may be low on refrigerant or it may have a faulty expansion valve.

How does an AC expansion valve work?

AC expansion valves work by controlling the amount of refrigerant flows to the evaporator coils. It acts as restriction to provide a specific amount of refrigerant flows into the evaporator coils. This is the basic principle behind any metering valves.

What is the expansion valve on a home AC condenser unit?

The expansion valve regulates the amount of refrigerant funneled to the evaporator from the condenser and compressor. This part also depressurizes the refrigerant until it becomes cold enough to cool down the warm air passing through.

What is an expansion valve in a car?

An expansion valve is an AC component that is commonly found on many road going vehicles. It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the vehicle’s AC system.

Why do I need to replace my expansion valve in my car?

AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system. Diagnosing your car’s air conditioning system may reveal that your expansion valve or the orifice tube needs to be replaced.

Why does my air conditioner have an expansion valve?

If your air conditioning (AC) has been less than helpful this summer, it may be the expansion valve (also known as an orifice tube). AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system.

Where is the a / C expansion valve located in a car?

The A/C 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.

What is the expansion valve on a home AC condenser unit?

Where is AC expansion Vale located?

The expansion valve is located on the AC piping which is in the evaporator box , under the dashboard. The entire evaporator box must be removed to gaiun access to the expansion valve. This is not an ‘easy’ job.

How does AC expansion valve system work?

How does an automotive AC expansion valve system work. Many car makers now use automotive AC expansion valve in their AC systems. An expansion valve is simply a refrigerant metering device to control the rate of flow of refrigerant into the evaporator located in your dash . In the illustration below, you’ll see that low pressure gas flows out of the evaporator coil and through the expansion valve.

What is block expansion valve?

A block style expansion valve uses a temperature sensing disc rather than a remote sensing bulb. A block expansion valve has both the liquid and vapor lines running through it. The sensing disc detect changes in exiting gas temperature and moves a tapered needle into or out of a metering port. How expansion valves fail.
