Review of RESSAC Climate Control

Sergio services my entire market and I’m lucky to run into him every few months. He’s communicative and always let’s us know what service he is performing and always asks if there is anything else he can help us with While he is there. Jenny Craig Los Angeles/Ventura county is super lucky to have him!

Dispatched our technician to a pharmacy in LA County that reported a cooler not operating. Upon arrival our refrigeration tech inspected the unit and found the breaker tripped. Unit had a badly clogged condenser coil that needed to be cleaned and blown out. After wiping down the cabinet area and testing all components, our tech reset the system. Open air cooler back online and operating at 39 degrees.
