No Cooling, but system running..

Problem:

Customer had no cooling but noticed everything was running.

Refrigerant and Leak Check

Solution:

After running a few tests the JDK technician found the system low on refrigerant.  A leak check was performed with an electronic leak detector and a refrigerant leak was found on a copper tube inside the condenser.  The remaining refrigerant was removed from the system using a reclaimer and the copper tube was repaired using an oxy/acetylene torch set and solder.  The system was pressure tested, which it held, evacuated to over 600 microns of vacuum and recharged with new refrigerant to factory specifications, per instructions on inside panel of condenser.

Result:

The system now has no leaks, a complete refrigerant charge and cools properly.

Time Required:

Twenty minutes to locate problem and one hour to fix problem. Total time required including system check: 2 hours 30 minutes.
