Dispatched our refrigeration technician to an office in Riverside, CA, to replace a manufacturer warrantied compressor on a cooler. While pumping down the system, our technician noted that there was little to no refrigerant. Used leak detector and bubble test but was not able to locate leak. Spoke to manufacturer to confirm status of additional warranties. Will quote leak search to customer, holding new compressor at site until secondary repairs can be made.

Inspected a break room refrigerator for an office in Riverside County. The technician tested all components, including motors, electrical components and refrigerant pressures. Determined that the compressor had failed and will need to be replaced. Compressor should be under warranty.

A retailer at the Galleria at Tyler in Riverside, California, was scheduled today for pre-approved HVAC repairs. Multiple air conditioners needed work done to bring them back up to spec. Our technician replaced the crankcase heaters on three units and troubleshooted a failed damper actuator. Unit #1 received a new economizer screen, and our tech troubleshooted another unit that was not communicating. #3 had a failed compressor that we will need to quote out. Unit #2 will require a new actuator for the damper. All other A/C units are up and running again except for the issues on #2 and #3.

Responded to a no-cooling request at a Riverside County commercial property. Our HVAC technician found no power going to the unit. Found the breaker in the electrical panel off, not tripped. Was told by the manager on duty that a sign technician had been out working on their light-up signage the day before. Labeled the breaker as RTU #1 to avoid issues like this in the future. Once powered on, system is working well with a 52 degree supply temperature.

A restaurant in Riverside California reported that the cooling drawer for the raw meet was not working properly. Our refrigerant technician arrived and inspected the unit. Found the cooling drawer operating as expected, no issues with the electrical or refrigeration parts. The drawers however are bent, wheels damaged and rails off-center. Will need to order new wheels and tracks for the drawers. Site will need to push hard on drawers in the meantime to make sure they shut correctly.
