What is an expansion valve?

Why replace or restore my expansion valve?

Most a/c technicians will automatically change out the expansion valve as it’s commonly a source of air conditioning failure. A good indication that your expansion valve has failed or is failing is a negative or high system gauge reading. This is either as a result of contaminants clogging the valve up or valve failure.

Because many valves are no longer made, Classic Auto Air offers testing and reconditioning services for your original. There is also a good chance that a NOS or NORS might be available. Please call or Message Us!

Expansion valve reconditioning consists of:

  • Test
  • Flush clean internally
  • Clean externally
  • Zinc plate.
