John was brought in as part of a team when we were having our kitchen redone. The other guys kept trying to get us to run the ducts the shortest route rather than where we wanted it to go. John found a creative way to get it done the way we wanted and still worked great. We've been super happy with it since then. He helps us out with a bunch of little things and went above and beyond what we asked. It was nice to meet someone that wasn't just there and gone, but wanted to make sure we were happy and it worked well. I would recommend him.
