About Hwasung
Built by refrigeration engineers, run like a service company.
Hwasung Refrigeration started as a two-person repair crew and grew into a full-service commercial refrigeration and HVAC contractor. We work with restaurants, grocers, cold-storage warehouses, and property managers who can't afford a system going down.
Every technician we send out is factory-trained, background-checked, and equipped to diagnose the problem on the first visit — not the third.
