Desmond Lopez was fantastic. He was knowledgeable, courteous, and very informative about our AC issues. Really, I can not say enough things about him. Our issue was resolved quickly and we were very happy with the resolution of the service experience.

Henry is very professional. I also really appreciate his integrity. During his work on my AC unit he accidentally broke part of my system that was only needed for heating. I would have never known until cold weather set in and maybe not even then. The result would have been another service call and more fees. Instead, he came back another day with the correct part and fixed it at no charge. I like working with people and firms that have those kind of ethical standards. In a second visit from McCullough to fix my intermittently non-working air conditioner, Dillon promptly fixed the issue, explained what was wrong, and showed me how to restore my system if the same problem occurred again. Once again saving me additional service future service fees.
