RSD - Refrigeration Supplies Distributor

RSD , Refrigeration Supplies Distributor operates from a single Modesto location as part of a 80-branch network spanning 10 western states. Established to serve the commercial refrigeration and HVAC trade, the company holds a perfect 5-star average across 2 verified reviews. Contractor customers in the Central Valley and beyond draw from thousands of SKUs, with parts and equipment organized into 20 product categories. The distributor is open weekdays from 7 AM to 5 PM and remains closed on weekends, making same-day pickup runs a weekday morning errand for licensed technicians and maintenance staff.

RSD claims the distinction of largest independently owned refrigeration parts and HVAC equipment wholesaler in the western United States. Their product catalog includes name-brand compressors, refrigerants, controls, motors, and a dedicated tools-and-instruments section for field technicians. The company hosts a Refrigerant Suite portal as a central clearing house for regulatory information, while Total Control University offers online DDC training for building automation systems. Cooling tower inventory ranges from 5-ton to 500-ton models, serving commercial installation crews rather than residential homeowners. Contractor accounts access order history, balances, and online payment through the website portal.

John Rivara left the lone detailed review, describing RSD staff as super helpful, knowledgeable, and very friendly. He did not name a specific technician, but his endorsement arrived without prompting and suggests consistent counter-side interactions for contractors calling in part numbers. The company website does not surface case studies or named project writeups, so Rivara's brief testimonial carries more weight than typical click-through reviews because it names personal disposition rather than quoting pricing or turnaround speed.
