The worst experience of my life. They are not professional. They charge you for the time wasted by them. Lazy at work and unprofessional. In both visits, the guy stood in front of the heating system for hours to figure out what the problem was, then called his boss to tell him what to do. The worst part is that they also charge you one hour for the time taken from the company to my place to start the repair and one hour back. worst company ever
