Attention: Mr. Nathan Vasquez, Supervisor
Subject: Locate and Repair Refrigerant Leak in Community Center, Data Cabinet A/C System.
Dear Vasquez,
Thermal Mechanical Service was dispatched to the Community Center, Data Area to check the A/C Unit
as it was not cooling. Our previous response about 2 to 3 months earlier we had located a small
refrigerant leak at the Schrader Access Port. That was repaired, tested, and placed back into operation.
We are clear that the earlier leak repair wasn't the only loss of line integrity that was causing additional
refrigerant lose. This is a difficult system to gain access to. Our approach was to remove the remaining
refrigerant charge, isolate the (3) major components and pressure test them independently to pin point the
area of concern. Having completed that process, we now know that there is a small leak somewhere in
the interconnecting refrigerant line set. The (2) lines will have to be replaced.
The Failed Line Sets are about 50' long running from the Condensing Unit to the Air Handler Unit. They
weave through the ceiling over offices and hallways.
For a Project Price of$9,827.74 we can complete the needed repairs. As a Good Faith attempt to help
cover this unusual failure Thermal Mechanical will Not charge any fees for the refrigerant required in the
recharging process.
Our Service Repair will also be warranted for a period of one year from the date of completion. Should
you have any questions please contact Our Service Department Offices. We are sorry for the disruption
this repair has caused.
