Can not say anything good about the ethics of this company after using them for an annual ac service that I won in the P.O.R.A. Vendors Fair Event in Sun City West several months back. Technician said I need some major work on my ac unit, duct cleaning. Got a second opinion, the second companies technician look at me after saying all was fine, and I said but another company recomended this and that. So let say I lost faith in Ron Brocks.
