Received a report regarding a freezer running at high temperatures in Thousand Oaks, California. Upon arrival, our technician found the system had dropped to 0 and was not correctly coming in and out of defrost. Determined that the defrost timer was failing. Sourced the part from the local supply house and replaced it. Cycled unit and brought it back below freezing. System is back online.

A/C repair tech returned to a home goods store in Thousand Oaks, California, to complete approved repairs on the Trane package units. Two units needed new capacitors, RTU #1 needed a leak repair on the first stage, and unit #3 needed the condesner fan motor replaced. Our technician completed the repairs as quoted, confirmed that all units were up and running well again except for RTU #3. Will need to return with a guard for the condenser fan motor shaft, but store is cooling for now.

Thousand Oaks a/c tech arrived at a vitamin store to investigate one of the units making a loud noise. Unit had been powered down to stop the noise and would no longer turn back on. Our technician discovered that the transformer had failed, was able to source and replace. Also found that the drive belt had torn, which had caused the original noise complaint. Unit working again after transformer and belt replacement.

A gift shop on Hillcrest Drive in Thousand Oaks, CA, reported a pipe leaking that may be HVAC related. Tech arrived and found their unit frozen up and the blower not running. After troubleshooting, pinpointed the issue to a fan relay not correctly wired to the board. Defrosted unit, fixed wiring, adjusted air handler for better pitch. Unit up and running again.
