A health center in Riverside County requested service on their Traulsen freezer that was spiking high temperatures. Upon arrival, our technician found the unit low on refrigerant with a dirty condenser coil. Cleaned the coil, repaired the discharge service valve and recharged the system. Freezer back to -5 degrees and functional. Job complete.

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.

Responded to an urgent refrigeration call for a commercial customer in Riverside California. Our service tech found their Traulsen freezer running at 40 degrees and repeatedly tripping the breaker. Diagnosed the problem, found a potential relay burnt and a failed capacitor. A short circuit caused the electrical outlet to burnout as well. Sourced necessary parts from the local supplier, return and replaced the electrical outlet, relay and capacitor. Tested system and waited for it to return to correct freezing temperatures. Job complete.
