used them for my a/c repair and was very satisfied. Had another company come out and repair my a/c they said for another 90.00 they would go ahead and get the service done on it. three months later a/c went down again and the insurance sent this company out he took pictures of the inside and coils and it showed the other company never did a thing. I never feel like this guy is lying to me. seems like he goes out of his way to show you everything he has done. will continue to use them for my a/c needs.
