Bill came out today with another gentleman, John I believe, and concluded that the problem was NOT with cracks in the slab but something related to my A/C compressor. Bill was a real gentleman, professional, kind, informative, gracious. I wanted to leave this review because even though I will not be working with your company to fix the problem I am having, I wanted to register my great appreciation for the time you folks took to help me out with this. Thanks and kind regards, David Hertzberg
