The technician was super friendly and seemed very knowledgeable. He got to the bottom of things in a few minutes whereas others had bumbled around and given me the run around. He spent all the time needed to thoroughly explain everything to me.
I also had my handyman over, who is very knowledgeable with a lot of mechanical things, and he was very impressed with the guy as well. I definitely feel comfortable with this guy being upfront and honest with me.
