I was not in trouble watching the technician fixing the problem for he's an expert in performing the task. He's a well-trained technician, thus he's not having difficulties in solving the issues that occurred in my unit. As I observed him, he was able to locate where the problems started, thus applying the best solutions was just quick for him. I was super happy that he's the one I hired for hvac air conditioning repair. He made an awesome repair. Our unit was working properly again.
