Called them out 5 times for the same problem on the same unit within a month's time. After it went down the 6th time, I called another company that found out what the problem was. I refused to pay for the labor on the last bill due to their complete incompetence. They turned around and put my furnishings up for Sheriff sale. - Prompt service, but totally inept and shady. They do not stand by their work. Talked with several other Restaurant owners as well as the constable that served the execution sale and they all have had similar experiences with Williams. Use at your own risk.
