After 15 years of good service and great technicians when it came to a warranty job on a refrigerated cooler Climate Master did not act on approval by Brivis to do the job demonstrating disregard for customer service. I then went directly through Brivis but it took FOUR months from the original diagnosis to finally be fixed, totally unsatisfactory and distressing over an extremely hot summer. Climate Master did not have the courtesy to reply to a letter I sent them either. I do NOT recommend Climate Master.
