I called the tech refrigeration to fix a leak on a display fridge thinking they will do a better job than the previous technician. They came up, fixed the same leak as the previous technician and put in freon. They charged me $600 for a job I previously paid $150. Two weeks later it leaked again. I called them, they refused to come up and fix it claiming that they dont offer a warranty for their work. I have no idea what kind of business they are in. Stay away unless you wanna be ripped off by them like me. If I could give them less than one star I would.
