A customer comes into my shop and says can you make me a hose?

As told to MACS Staff by Marks Air

We received this story from MACS member Gordon Marks at Marks Air in Tampa, FL. Gordon is a frequent contributor to the MACS blog.
A customer came in with his farm tractor on a trailer and said,  “Leroy told him that we could make a hose for his A/C system and that the discharge service valve was leaking.”


This is a picture of what Marks Air found. Service professionals will appreciate this, if you don’t get it you need to become a MACS member.


He unloaded the tractor and left it with Marks Air.

In addition, to the hose, the clutch was intermittent and they found that the wiring on the switch (it was an electronic control so the wires were very small) was broken and had to be re-soldered.

There was still low voltage (11.5VDC) so they put a relay in the circuit rather than chasing it.

Oh, we also made a hose, replaced the drier, evacuated and  recharged it. This is a good example of why professional service is important.

    Not surprising Gordon I could write a book on some the things I’ve seen.
