SERVICE HINTS FOR REFRIGERANT LEAK DETECTION

Page 1 of 3

Use of electronic leak detectors for checking A/C systems refrigerant leakage is the only
method approved by TMS. This type of leak detector is sensitive not only to refrigerant, but
also sensitive to numerous petrochemical substances (motor oil, gasoline, solvents, etc.)
commonly found in a repair shop environment. Because this sensitivity could diminish the leak
detector ’s capacity for accurate leak detection, some service hints have been provided to help
increase the accuracy of your diagnosis.

SERVICE HINTS:

1.

Visual Inspection: Do a quick visual inspection under the hood for signs of refrigerant
leakage. Check for areas of heavy oil leakage at block and piping joints. Many times
these areas have accumulated road dust and dirt.

2.

Inspection with leak detector: NOTE: Make sure the system is fully charged. Operate
the system to increase refrigerant pressure. Shut the system off before inspecting with
leak detector.

A.

Checking for leakage at a joint: Wipe the oil/dirt accumulation off the joint with a
clean rag. Do not use solvents to clean the joint. Refrigerant is heavier than air so
start checking for leaks with the detector wand about 1/4 in. below the joint. Move the

wand slowly across and around each joint (see illustration below).

Piping Joint

Move detector wand slowly across

and around each joint.
