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. The expansion valve, also known as an orifice tube in some designs, regulates the pressure of refrigerant that enters the evaporator. The tube is also where liquid refrigerant under pressure converts to a gaseous form. The gaseous refrigerant absorbs heat from air passing through the evaporator core and carries it to the condenser where the heat is removed.

In a situation where the orifice tube is either blocked or stuck open, the air conditioning will not cool properly. Too much refrigerant will cause frost on the core and prevent air from passing through to cool the air temperature. Too little refrigerant passing through the evaporator means not enough heat is absorbed and the interior is insufficiently cooled. In either situation, you may need to replace the expansion valve/orifice tube.

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.
It is possible for the expansion valve to become blocked by excessive moisture in the air conditioning system, which would indicate a receiver/drier problem.

How it's done:

The AC refrigerant is removed from the system
The defective expansion valve is removed
The new expansion valve is installed
The a/c system is recharged with refrigerant
The a/c system is tested for leaks and proper operation

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.

What common symptoms indicate you may need to replace the Expansion Valve (Orifice Tube)?

Air conditioning doesn’t cool sufficiently
Air conditioning expansion valve is frosty but the air conditioning isn’t blowing cold air

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.

Pontiac Grand Prix V6-3.8L Turbo - Brake System Flush - Englewood, Colorado

Started having braking issues on my 05 Pontiac Grand Prix. Brake pedal would get squishy and then go to the floor. ABS light, and traction control lights illuminated on the dash. Service ABS System, Service Traction Control System, and Service Stability Control System warnings flashing on the systems warnings console. Initial inspection under the hood revealed a bone dry brake fluid reservoir. Brake fluid leaking from the ABS pump. Replaced the ABS pump and the anti-lock control module. Topped off the brake fluid, and called in Robert from Yourmechanic.com to come out and do a brake system flush to bleed the air out of the lines and put in fresh new brake fluid. Second time hiring Robert to come out and do work for me. He arrived early for the appointment time, about 30 minutes, which was awesome. I knew he did great work, so I let him have at it. 90 minutes later I was driving down the road testing out the brakes without any issues, no idiot lights coming on, no warnings flashing me in the face. Yourmechanic.com is the best way in the universe to get low cost, quality auto repairs done right the first time. Thanks guys.
