Kevin did a great job installing the remote compressor for our pastry case. We only had good experiences with this company, they get back to you right away when you request a service call and can fix most things right away if they have the parts.

Dispatched our LA County refrigeration technician to a restaurant for their kitchen line reach-in not operating. After acquiring equipment data for the first inspection, our technician found the evaporator coils iced over. Determined that a previous contractor had set the temperature settings too low at 26 degrees. Adjusted the settings and tested the defrost clock. Unit back down to 37 degrees and dropping. No more items to report.

Dispatched our Glendale California area technician back to a retailer to continue troubleshooting their A/C unit. Upon inspection, our tech found the Trane split system with an over-amping blower motor. Will need to quote a replacement to the customer, and will need a second technician to remove/replace.

Dispatched our Glendale CA commercial HVAC technician to a bakery in need of water chiller repairs. The system needed a new compressor per customer report. Upon arrival, our technician recovered the refrigerant and installed the new compressor, filter drier and access valves. Pressurized system to test for leaks and found none. After hooking up all electrical components, found the agitator pump was not functional. Customer stated they would take care of that repair themselves. System is off until agitator motor is replaced, but otherwise functional and ready for use once that is complete.

Dispatched one of our commercial refrigeration service techs to a customer in Glendale, CA, to inspect their sandwich case that had been previously repaired by the customer. Found the unit cycling off prematurely after customer replaced the temperature control themselves. Inspected the sensing bulb and found ice build up inside the“well” ( where the sensing bulb of temp control reads the evap temp). The “well” has ice inside of the pipe, causing the refrigerator temperature control to shut off prematurely. This was due to necessary putty on end of well missing, allowing moisture into the pipe and freezing. Tech relocated sensing bulb of temp control and monitored operations. Unit was cycled on and off multiple times. Temperatures are now at 38 degrees and box is functional again. Unit is cycling off correctly at 34 degrees, and turning on again at 40 degrees. Job complete.

An international retailer in Glendale, California, reported a strong odor coming from the AC vent. Upon arrival, technician inspected equipment. Minor issues resolved including loose belt and old filters. Noted that the fresh air vent for the unit was located in an alley near where the trash bins were kept. Added deodorizer to the system. Was unable to notice any smell while onsite, will monitor but deodorizer and new filters should assist with intermittent issue.
