I liked Sevan's kindness and patience for he was able to handle the situation calmly. He's a crafty technician for he knew the best techniques on how to perform hvac furnace services expertly. He was quick to find the right solutions and was thorough in fixing up the problem. After the repair, I even tried to check it just to make sure if it was repaired well. I was overwhelmed for it was working perfectly. Great job, Sevan!
