How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do you need for an AC expansion valve replacement?

Your car’s AC consists of a condenser, an expansion valve, an evaporator core, and a compressor, among other parts. Tubes containing pressurized refrigerant connect every part of the system. When the refrigerant is at its coldest (around the evaporator), it absorbs moisture from the air being blown into the cabin, and when it’s at its warmest, it’s already on its way back to the compressor and condenser.
If your AC unit is on the fritz, the total parts bill could include:
  1. New
    air conditioning expansion valve or orifice tube
    ($2-$270): The AC expansion valve (or orifice tube) removes pressure from the cool, liquid refrigerant before it passes to the evaporator. Recommended brands are UAC (Universal Air Conditioner), Four Seasons, and AC Delco.
  2. Replacement air conditioning evaporator core ($2-$415): Relieved of pressure, the cooled refrigerant can now expand into a gas and absorb all the heat from the air passing through the evaporator on its way to the vents in the cabin. It then makes its way to the compressor. We recommend brands like UAC (Universal Air Conditioner), Four Seasons, and TYC.
  3. New
    air conditioning compressor
    ($30-$4,100): At the next stop in the cycle, the warm cloud of refrigerant flows into the compressor to be pressurized and forced back into a liquid state. Recommended brands include Denso, Four Seasons, and UAC (Universal Air Conditioner).
  4. New
    air conditioning condenser
    ($70-$880): The condenser looks like a miniature radiator. The warm, liquid refrigerant passing through its coils sheds its heat against the outside air before moving through the expansion valve or orifice tube. Recommended brands include Spectra Premium, TYC, and Four Seasons.
You can buy expansion valve replacement parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.m
Keep in mind: While an orifice tube replacement requires only a single part, you might also require a new condenser or evaporator to repair your car’s AC.
Original Equipment Manufacturer (OEM) parts cost more than aftermarket parts, but they often include better warranties. For example, asking a Toyota mechanic to install a genuine expansion valve will net you a 24-month/25,000-mile warranty. That being said, some aftermarket performance parts manufacturers are very competitive with the quality of OEM parts.
You can buy replacement parts at automotive body shops, parts shops like NAPA Auto Parts, Advance Auto Parts and AutoZone, dealerships, or online stores like Amazon and RockAuto. If you prefer OEM parts, you can also try your vehicle manufacturer’s official website. Ford, Nissan, and just about every other car maker sell OEM parts online. Check your owner’s manual for any crucial specifications so you don’t buy the wrong part.

How will a mechanic replace my car’s expansion valve?

An expansion valve replacement requires special equipment, training, and caution. Your mechanic will have to:
  1. Unseal the AC unit of your car
  2. Evacuate the refrigerant and test it to see if it’s recoverable or too contaminated for re-use
  3. Locate the expansion valve (or orifice tube), disconnect the AC hoses, and cap them
  4. Unfasten and remove the expansion valve or orifice tube
  5. Install the new expansion valve or orifice tube
  6. Replace the O-rings that seal the valve or tube and the refrigerant lines
  7. Reconnect the refrigerant lines
  8. Recharge the cooling system with recovered or fresh refrigerant
The refrigerant in your car is a regulated substance (not to mention toxic), so you shouldn’t replace the expansion valve on your own. Leave it for a professional.

What happens when an expansion valve goes bad?

An expansion valve (orifice valve) in your car's air conditioning system serves as a bottleneck. It receives high-pressure refrigerant and depressurizes it into gas for the compressor. If the valve is clogged, the compressor may overheat. The AC high-pressure hose could also burst, spraying corrosive refrigerant into the other components.

What is an expansion valve (orifice tube) replacement?

Refrigerant is the lifeblood of your car’s air conditioning unit. The expansion valve or orifice tube controls the pressure and amount of refrigerant entering the evaporator. An expansion valve (or orifice tube) replacement involves removing the valve and installing a new one.

When should I replace the expansion valve in my car?

The expansion valve converts refrigerant from liquid to gas for use in the evaporator core. Without a properly functioning expansion valve, your car’s air conditioner will begin to malfunction. 
A broken valve could cause too much refrigerant to flood the system, causing the AC unit to freeze, but not emit cold air. At the other extreme, too little refrigerant will cause the condenser to simply stop working, resulting in a cabin full of hot air. 

How long does an AC expansion valve last?

There is no generally-accepted life expectancy for a car expansion valve or orifice tube. It should last for the lifetime of the car, but it can be affected by wear and tear over time. You will probably have to replace your expansion valve at some point if you live in a hotter climate, especially if you don’t take your car in for routine maintenance.

Is it easy to replace a car expansion valve yourself?

Replacing an AC orifice tube isn’t a great DIY project. It requires specialist equipment to evacuate and replace the refrigerant in the lines, and it could be dangerous. The refrigerant in your car is toxic, flammable, and corrosive. If it gets contaminated before it gets back in the lines, it could affect other parts of the cooling system.


The most common causes of expansion valve and orifice tube failure are age, wear, moisture, or contaminants like dust and dirt. Age and wear are self-explanatory; all the components in your AC (especially those containing high-pressure liquid) will thin and loosen over time. But you can prevent moisture and contaminants from entering your car's cooling system by
cleaning the AC condenser
and replacing the HVAC
car air filter
Depending on the vehicle, the expansion valve can be located under the hood, under the dashboard, or near the firewall. You’ll have to check your model’s repair manual to be sure. If you can't find the expansion valve, your car might use an orifice tube, which is located within the AC high-pressure hose to the evaporator.
Yes, a bad expansion valve might cause a refrigerant leak. An expansion valve is comprised of several small valves and chambers that regulate how much refrigerant enters the evaporator. A clog or a malfunction, in combination with high pressure, can easily cause the unit to leak.
