"Fernie Guerrero mastered his customer service skills when he went out of his way to help us out. We had a slight problem when our unit was not working properly. Called and requested a technician to come out to observe the problem. Within an hour, Fernie went completely out of his way to assist us. He literally went far and beyond out of his schedule to fix the problem. I really appreciate his technical support to help us out in this situation. I highly recommend Fernie as an excellent technician for Total Air."
