What causes expansion valve failure?

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 valve is stuck open, too much refrigerant is allowed to pass through the system and into the compressor.

How do you know if your expansion valve is bad?

4 Symptoms of a Bad A/C Expansion Valve (& Replacement Cost)

1. #1 – Poor Air Conditioning Performance.
2. #2 – Inconsistent Airflow From Vents.
3. #3 – Air Conditioning Constantly Running.
4. #4 – Frost Forming on A/C Compressor or Vents.

Where is the expansion valve located?

TXV Location The thermostatic expansion valve is usually mounted inline with the tube that supplies liquid coolant to the air conditioner evaporator. The bulb of the expansion valve is mounted to the outside of the output line of the air conditioner evaporator.

What happens if expansion valve goes bad?

You will notice when the A/C expansion valve goes bad because your air conditioning system will ultimately stop functioning properly. It will either produce less cool air or it won’t produce any cool air at all.

How much does a AC expansion valve cost?

The average cost for air conditioning expansion valve replacement is between $267 and $308. Labor costs are estimated between $158 and $199 while parts are priced at $110. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

What does an expansion valve do on an AC unit?

The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm. This may be verified by feeling the liquid line at its connection to the expansion valve.

Does the expansion valve need to be replaced?

There isn’t a specific lifespan of the valve, it’s more just a wear and tear kind of situation. 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.

What causes an expansion valve to freeze?

If moisture enters the air conditioning system, it freezes at the system’s metering device. If the drier becomes saturated with moisture, it releases it at the hottest times of the day. This moisture freezes in the expansion valve and deprives the evaporator of refrigerant.
