Sergio is the absolute best! Fair, honest, and just a really nice guy. He's not only shown me the problems when he's been here. But he also explains the issue, how to prevent the issues, and how to properly maintain your unit. The issues I had were small, and I had companies out before him that either misidentified the problem, or we're out for a larger payday, and didn't fix my problems. Sergio is, in my opinion, the best. He has earned a customer for life by doing his job, not taking advantage of his customers, and being the fair and honest person he is. He is the best of the best. Don't hesitate and call 1st Choice today if you have problems. You will not be disappointed. Thanks Sergio.
