Review of RESSAC Climate Control

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 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.

RESSAC technician returned to surgery center in Glendale California, to turn the system back on after it had defrosted overnight. Brought filters to replace over recovery room, also spray cleaned the evap coil and adjusted the fan belt. Coil is getting a steady covering of fine dust from nearby remodel, may need another coil cleaning in near future.
