    Brennan was one of the nicest and most helpful techs i've ever worked with for just about anything on the house. Sometimes it can be difficult when you don't know much about the systems that they're working on, but he seemed very trustworthy, and just wanted to help and do a good job without trying to give us a sales pitch. I would use John Lock again for anything hvac related, and I also would highly recommend them to anyone else. Very fair pricing and it was a great experience.
